Response to Arguments
Applicant's arguments filed 3/11/2026 have been fully considered but they are not persuasive.
Regarding claim 1, applicant argues that Gulati and Xiao, taken alone or in combination, fail to disclose each and every feature recited in amended claim 1. Examiner respectfully disagrees noting that, per 35 U.S.C. 103, a patent for a claimed invention may not be obtained if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains (see §MPEP 2141).
Applicant argues that Gulati and Xiao, taken together or in combination, fail to disclose "measur[ing] a channel characteristic for a plurality of resources of a communication channel", "identify[ing] one or more resources of the plurality of resources for which the channel characteristic fails to satisfy a threshold, wherein the one or more resources are identified based at least in part on a comparison of the channel characteristic to the threshold," and "interleav[ing] a plurality of coded bits to form a plurality of interleaved coded bits, the plurality of coded bits including a set of systematic bits and a set of parity bits, wherein a first subset of parity bits of the set of parity bits is mapped to the one or more resources” as recited in amended claim 1 because Xiao instead discloses measuring channel quality at a UE, comparing measured channel qualities to one another, and indicating in a bit map those RBs or RBGs whose measured channel quality exceeds a channel quality threshold, failing to disclose identifying one or more resources of a plurality of resources based at least in part on a comparison of a channel characteristic to a threshold such that a first subset of parity bits of the set of parity bits is mapped to the one or more resources. Examiner respectfully disagrees noting that [0037]-[0038] of Xiao disclose a UE that, in response to measuring a channel quality of one or more RBGs (i.e. a plurality or resources), indicates in a bit map a ‘0’ for each RBG whose channel quality is below a channel quality threshold (i.e. by comparing the measured channel quality to a channel quality threshold). Thus, Xiao teaches of "measur[ing] a channel characteristic for a plurality of resources of a communication channel", and "identify[ing] one or more resources of the plurality of resources for which the channel characteristic fails to satisfy a threshold, wherein the one or more resources are identified based at least in part on a comparison of the channel characteristic to the threshold,".
Applicants argues that Xiao fails to teach, "interleav[ing] a plurality of coded bits to form a plurality of interleaved coded bits, the plurality of coded bits including a set of systematic bits and a set of parity bits, wherein a first subset of parity bits of the set of parity bits is mapped to the one or more resources”, and Gulati fails to cure the deficiencies of Xiao. Examiner respectfully disagrees noting that Gulati discloses this limitation (e.g. see Figs 5-6 and [0119], [0144] & [0146]-[0150] and discussion for 35 USC 103 rejection of claim 1 in this action item below). Therefore, it would have been obvious to combine the teachings of Gulati and Xiao to disclose all the limitations of amended claim 1.
Based on the above discussion, examiner maintains rejection of claim 1 under 35 USC 103 based on Gulati in view of Xiao.
Regarding claims 18, 29 & 30, applicant submits that claims these claims are patentable based on similar amendments and arguments made for claim 1. Examiner respectfully disagrees and for the same reasons as discussed above maintains rejections of claims 18, 29 & 30 under 35 USC 103 based on Gulati in view of Xiao.
Regarding claims 2, 3, 5-17, 19, 20 & 22-28, applicant submits that claims these claims are patentable based amendments and arguments made for claims 1, 18, 29 & 30 and due to their dependency on claims 1, 18, 29 or 30. Examiner respectfully disagrees and for the same reasons as discussed above maintains rejections of these claims under 35 USC 103 based on Gulati in view of Xiao.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1, 2, 7, 9-14, 17-19, 24, 26 & 28-30 are rejected under 35 U.S.C. 103 as being unpatentable over Gulati et al. (US 20200266957)(herein after “Gulati”) in view of Xiao et al. (US 2009/0028260)(herein after “Xiao”).
Regarding claims 1 & 29, Gulati discloses a transmitter wireless communication device for wireless communication ([0006] discloses a first wireless communication apparatus that may be a first device capable of transmitting a bit sequence to a second device.), and a method of wireless communication performed by a transmitter wireless communication device ([0005] discloses a method for wireless communication by a first device (i.e. a wireless communication device) capable of transmitting a bit sequence to a second device.), comprising:
one or more memories ([0006] discloses that the first wireless communication apparatus may include memory.); and
one or more processors, coupled to the one or more memories, individually or collectively configured to cause the transmitter wireless communication device to ([0006] discloses that the first wireless communication apparatus may include a processor, coupled to the memory, that may be configured to perform the functions in the disclosed inventions.):
identify one or more resources, of the plurality of resources, for which the channel characteristic is vulnerable ([0125] discloses that a transmitting device (i.e. first device) may determine one or more resources, for example one or more symbols, in a plurality of resources or symbols of a wireless communication system, which are less likely to be received correctly at a receiving device and are considered vulnerable. [0131] discloses that resource elements may not have the same quality (i.e. the same channel characteristics), and thus vulnerable symbols or resources may be identified as symbols or resources that experience interference from other traffic, or symbols or resources where a reference signal is not present and require interpolation of a channel.);
interleave a plurality of coded bits to form a plurality of interleaved coded bits, the plurality of coded bits including a set of systematic bits and a set of parity bits, wherein a first subset of parity bits of the set of parity bits is mapped to the one or more resources (Fig 5 & [0144] disclose interleaving of a plurality of coded bits including a set of higher priority coded bits and a set of not higher priority code bits (i.e. a set of lower priority bits such as parity bits). [0119] discloses that higher priority bits may include systematic bits. The set of higher priority systematic bits are shown in gray in fig 5 and the set of low priority parity bits are shown in white in fig 5. [0144] discloses that lower priority bits may be assigned to resources which are more likely to be unsuccessfully received (i.e. channel characteristic is vulnerable). Fig 6 & [0146]-[0150] disclose an example where a first subset of parity bits (i.e. white blocks in fig 6) from the set of parity bits is mapped to resources identified as vulnerable and labeled Er(v). Note that the white blocks interleaved in the Er(v) resources 635 represent a first subset of the low priority parity bits while a second subset of low priority parity bits are shown as white blocks interleaved in the Er(nv) resources 630.); and
transmit a communication including the plurality of interleaved coded bits (Fig 9 & [0173]-[0175] discloses at step 920 that a UE transmits a bit sequence that includes the plurality of interleaved coded bits.).
Gulati fails to disclose wherein the transmitter wireless communication device is caused to measure a channel characteristic for a plurality of resources of a communication channel; and wherein the identifying is for which a channel characteristic fails to satisfy a threshold, wherein the one or more resources are identified based at least in part on a comparison of the channel characteristics to the threshold.
However, Xiao teaches wherein the transmitter wireless communication device is caused to measure a channel characteristic for a plurality of resources of a communication channel ([0037]-[0038] disclose a UE that measures a channel quality of one or more RBGs (i.e. a plurality or resources). Fig 2 & [0017] disclose that the UE includes a transmitter (i.e. UE is a transmitter wireless communication device).); and
wherein the identifying is for which a channel characteristic fails to satisfy a threshold, wherein the one or more resources are identified based at least in part on a comparison of the channel characteristics to the threshold ([0037]-[0038] discloses identifying a resource block (RB) to have a channel quality below a channel quality threshold and indicating by a 0 in a bit map corresponding to RBs whose channel quality fails to exceed the channel quality threshold (i.e. by comparing the measured channel quality to a channel quality threshold).).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have a transmitter wireless communication device, or a method of wireless communication performed by a transmitter wireless communication device, identify when a channel characteristic is vulnerable, as disclosed by Gulati, and measure a channel characteristic for a plurality of resources of a communication channel; wherein the identifying is for which a channel characteristic fails to satisfy a threshold, wherein the one or more resources are identified based at least in part on a comparison of the channel characteristics to the threshold, as taught by Xiao. The motivation to do so would have been to have a transmitter UE, or a method for a transmitter UE to, measure the channel quality of a plurality of symbols or resource blocks of a communication channel and identify symbols or resource blocks as being vulnerable when the measured channel quality fails to be above a quality threshold so that the transmitter UE can perform interleaving that prioritizes lower priority parity bits to be transmitted on the symbols or during the resource blocks that fail to be above the quality threshold in order to improve decoding performance at a receiver.
Regarding claim 2, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 1.
Gulati fails to disclose wherein the one or more resources are identified at a per-resource-block (RB) resolution.
However, Xiao teaches wherein the one or more resources are identified at a per-resource-block (RB) resolution ([0037]-[0038] discloses identifying a resource block (RB) to have a channel quality below a channel quality threshold and indicating by a 0 in a bit map corresponding to RBs whose channel quality fails to exceed the channel quality threshold.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the transmitter wireless communication device of claim 1, as disclosed by Gulati in view of Xiao, wherein the one or more resources are identified at a per-resource-block (RB) resolution, as taught by Xiao. The motivation to do so would have been to have a transmitter UE identify a resource block of a communication channel as being vulnerable by determining that the channel quality of the resource block fails to be above a quality threshold so that the transmitter UE can perform interleaving that prioritizes lower priority parity bits to be transmitted during the resource blocks that fail to be above the quality threshold in order to improve decoding performance at a receiver.
Regarding claim 7, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 1.
Gulati fails to disclose wherein the one or more processors are further configured to cause the transmitter wireless communication device to: receive a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold, and wherein the one or more processors, to cause the transmitter wireless communication device to identify the one or more resources, are configured to cause the transmitter wireless communication device to: identify the one or more resources using the communication.
However, Xiao teaches wherein the one or more processors are further configured to cause the transmitter wireless communication device to: receive a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold, and wherein the one or more processors, to cause the transmitter wireless communication device to identify the one or more resources, are configured to cause the transmitter wireless communication device to: identify the one or more resources using the communication ([0038]-[0040] discloses a UE receiving a channel assignment from a RAN that identifies an RBG, based on the received channel quality message that includes the bit map indicating which RBGs fail to exceed a channel quality threshold with a 0. A broadest reasonable assumption is that the RBG assignment by the RAN and received by the UE is an RBG indicated with a 0 in the bit map (i.e. one that fails to exceed the channel quality threshold), that causes the UE to identify, using the RBG assignment communication, the assigned RBG.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the transmitter wireless communication device of claim 1, as disclosed by Gulati in view of Xiao, wherein the one or more processors are further configured to cause the transmitter wireless communication device to: receive a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold, and wherein the one or more processors, to cause the transmitter wireless communication device to identify the one or more resources, are configured to cause the transmitter wireless communication device to: identify the one or more resources using the communication, as taught by Xiao. The motivation to do so would have been to have a transmitter UE be able to identify a vulnerable RBG by receiving a communication from a RAN indicating an RBG, of a plurality of RBGs, as being a vulnerable RBG that fails to be above a channel quality threshold so that the transmitter UE can perform interleaving that prioritizes lower priority parity bits to be transmitted on the communicated vulnerable RBG in order to improve decoding performance at a receiver.
Regarding claim 9, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 7.
Gulati discloses wherein the communication is received in at least one of radio resource control (RRC) signaling ([0168] discloses that configuration and parameters for the resource pool within which the resources are selected may use RRC signaling.), downlink control information (DCI) (optional), or uplink control information (UCI) (optional).
Regarding claim 10, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 1.
Gulati fails to disclose wherein the one or more processors are further configured to cause the transmitter wireless communication device to transmit a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold.
However, Xiao teaches wherein the one or more processors are further configured to cause the transmitter wireless communication device to transmit a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold (Fig 5 & [0033] disclose a UE reporting back to a RAN a channel quality message. [0037]-[0038] disclose that the reported channel quality message may contain a bitmap indicating RBs whose measured channel quality fail to exceed a channel quality threshold by a 0 in the bitmap.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the transmitter wireless communication device of claim 1, as disclosed by Gulati in view of Xiao, wherein the one or more processors are further configured to cause the transmitter wireless communication device to transmit a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold, as taught by Xiao. The motivation to do so would have been to have a transmitter UE be able to measure channel quality of RBs, compare the channel quality of the RBs to a channel quality threshold, identify vulnerable RBs as RBs that fail to exceed the channel quality threshold, and report a bitmap back to a RAN indicating RBs that fail to exceed the channel quality threshold by a 0 in the bitmap, so that the RAN can select vulnerable RBs to communicate back to the transmitter UE for which the transmitter UE should perform interleaving that prioritizes lower priority parity bits to be transmitted on the vulnerable RBs communicated by the RAN in order to improve decoding performance at a receiver.
Regarding claim 11, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 1.
Gulati discloses wherein the plurality of coded bits comprises a group of bits to which a linear code has been applied ([0081] discloses that the techniques to map higher priority coded bits to symbols more likely to be successfully decoded may be implemented using LDPC base graph selection (i.e. a linear code).).
Regarding claim 12, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 1.
Gulati discloses wherein the communication is a downlink communication (Fig 9 & [0173]-[0175] discloses at step 920 that a first UE 115-e transmits (i.e. communicates) a bit sequence that includes the plurality of interleaved coded bits to a second UE 115-f. [0164]-[0165] discloses that a first device and a second device may be configured for D2d communication and the first device may be a transmitting device and the second device may be a receiving device. A broadest reasonable interpretation is that the communication from UE 115-e to UE 115-f is a downlink transmission using D2D communication.).
Regarding claim 13, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 1.
Gulati discloses wherein the communication is an uplink communication (Fig 9 & [0173]-[0175] discloses at step 920 that a first device (i.e. UE 115-e) transmits (i.e. communicates) a bit sequence that includes the plurality of interleaved coded bits to a second device (i.e. UE 115-f). [0179] discloses that the second may be a base station, in which case the communication from the first device (i.e. a UE) to the second device (i.e. a base station) would be an uplink communication.).
Regarding claim 14, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 1.
Gulati fails to disclose wherein the threshold is pre-configured on the transmitter wireless communication device.
However, Xiao teaches wherein the threshold is pre-configured on the transmitter wireless communication device ([0037] discloses that the channel quality threshold may be a predetermined value.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the transmitter wireless communication device of claim 1, as disclosed by Gulati in view of Xiao, wherein the threshold is pre-configured on the transmitter wireless communication device, as taught by Xiao. The motivation to do so would have been to have a transmitter UE base a channel quality threshold on a predetermined value that may be defined by a standard so that the channel quality threshold does not need to be communicated to the transmitter UE which saves channel resources.
Regarding claim 17, Gulati in view of Xiao disclose the transmitter wireless communication device of claim 1.
Gulati discloses wherein the plurality of coded bits is interleaved such that the set of systematic bits and a second subset of parity bits from the set of parity bits are mapped to one or more resources, in the plurality of resources of the communication channel, for which the channel characteristic satisfies the threshold (Fig 5 & [0144] disclose interleaving of a plurality of coded bits including a set of higher priority coded bits and a set of not higher priority code bits (i.e. a set of lower priority bits such as parity bits). [0119] discloses that higher priority bits may include systematic bits. The set of higher priority systematic bits are shown in gray in fig 5 and the set of low priority parity bits are shown in white in fig 5. [0144] discloses that lower priority bits may be assigned to resources which are more likely to be unsuccessfully received (i.e. channel characteristic is vulnerable). Fig 6 & [0146]-[0150] disclose an example where a set of systematic bits (gray blocks in fig 6) and a second subset of parity bits (i.e. white blocks in fig 6) from the set of parity bits is mapped to resources identified as not vulnerable and labeled Er(nv). Note that the white blocks interleaved in the Er(nv) resources 630 represent a second subset of the low priority parity bits while a first subset of low priority parity bits are shown as white blocks interleaved in the Er(v) resources 635.).
Regarding claims 18 & 30, Gulati discloses a receiver wireless communication device for wireless communication ([0038] discloses a second wireless communication apparatus that may be a second device capable of receiving a bit sequence from a first device.), and a method of wireless communication performed by a receiver wireless communication device ([0037] discloses a method for wireless communication by a second device (i.e. a wireless communication device) capable of receiving a bit sequence from a first device.), comprising:
one or more memories ([0038] discloses that the second wireless communication apparatus may include memory.); and
one or more processors, coupled to the one or more memories, individually or collectively configured to cause the receiver wireless communication device to ([0038] discloses the second wireless communication apparatus may include a processor, coupled to the memory, that may be configured to perform the functions in the disclosed inventions.):
identify one or more resources, of the plurality of resources, for which the channel characteristic is vulnerable ([0121] discloses that the second device may determine, based on receiving a bit sequence from the first device, that a second set of resources has a lower priority than a first set of resources in a plurality of resources of a wireless communication system, which are less likely to be received correctly at a receiving device and are considered vulnerable. [0131] discloses that resource elements may not have the same quality (i.e. the same channel characteristics), and thus vulnerable symbols or resources may be identified as symbols or resources that experience interference from other traffic, or symbols or resources where a reference signal is not present and require interpolation of a channel.);
receive a communication including a plurality of interleaved coded bits ([0211] discloses the second device may receive a bit sequence based on a first set of resources having a high priority than a second set of resources. Fig 5 & [0144] disclose that the bit sequence may be a plurality of interleaved coded bits including a set of higher priority coded bits and a set of not higher priority code bits (i.e. a set of lower priority bits such as parity bits) that are used to form modulated symbols. [0144] discloses that lower priority bits may be assigned to resources (i.e. symbols) which are more likely to be unsuccessfully received (i.e. channel characteristic is vulnerable).); and
de-interleave the plurality of interleaved coded bits to obtain a plurality of coded bits, the plurality of coded bits including a set of systematic bits and a set of parity bits, wherein a first subset of parity bits of the set of parity bits is mapped to the one or more resources (Fig 12 & [0212] discloses that a bit sequence decoding component 1255 at the second device may receive, demodulate and de-interleave the modulated symbols to obtain a plurality of systematic bits and parity bits (i.e. coded bits). Fig 6 & [0146]-[0150] disclose an example where the received signal contains a first subset of parity bits (i.e. white blocks in fig 6) from the set of parity bits that is mapped to resources identified as vulnerable and labeled Er(v). Note that the white blocks interleaved in the Er(v) resources 635 represent a first subset of the low priority parity bits while a second subset of low priority parity bits are shown as white blocks interleaved in the Er(nv) resources 630. Thus, the de-interleaving at the second device would be based on a first subset of parity bits from the set of parity bits being mapped to the one or more resources for which the channel characteristic is vulnerable.).
Gulati fails to disclose wherein the receiver wireless communication device is caused to measure a channel characteristic for a plurality of resources of a communication channel; and wherein the identifying is for which a channel characteristic fails to satisfy a threshold, wherein the one or more resources are identified based at least in part on a comparison of the channel characteristics to the threshold.
However, Xiao teaches wherein the receiver wireless communication device is caused to measure a channel characteristic for a plurality of resources of a communication channel ([0037]-[0038] disclose a UE that measures a channel quality of one or more RBGs (i.e. a plurality or resources). Fig 2 & [0017] disclose that the UE includes a receiver (i.e. UE is a receiver wireless communication device); and
wherein the identifying is for which a channel characteristic fails to satisfy a threshold, wherein the one or more resources are identified based at least in part on a comparison of the channel characteristics to the threshold ([0037]-[0038] discloses identifying a resource block (RB) to have a channel quality below a channel quality threshold and indicating by a 0 in a bit map corresponding to RBs whose channel quality fails to exceed the channel quality threshold (i.e. by comparing the measured channel quality to a channel quality threshold).).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have a receiver wireless communication device, or a method of wireless communication performed by a receiver wireless communication device, identify when a channel characteristic is vulnerable, as disclosed by Gulati, and measure a channel characteristic for a plurality of resources of a communication channel; wherein the identifying is for which a channel characteristic fails to satisfy a threshold, wherein the one or more resources are identified based at least in part on a comparison of the channel characteristics to the threshold, as taught by Xiao. The motivation to do so would have been to have a receiver UE, or a method for a receiver UE to, measure the channel quality of a plurality of symbols or resource blocks of a communication channel and identify symbols or resource blocks as being vulnerable when the measured channel quality fails to be above a quality threshold so that the receiver UE can perform de-interleaving knowing that lower priority parity bits received have been prioritized to be on the symbols or during the resource blocks that fail to be above the quality threshold in order to improve decoding performance at a receiver.
Regarding claim 19, Gulati in view of Xiao disclose the receiver wireless communication device of claim 18.
Gulati fails to disclose wherein the one or more resources are identified at a per-resource-block (RB) resolution.
However, Xiao teaches wherein the one or more resources are identified at a per-resource-block (RB) resolution ([0037]-[0038] discloses identifying a resource block (RB) to have a channel quality below a channel quality threshold and indicating by a 0 in a bit map corresponding to RBs whose channel quality fails to exceed the channel quality threshold.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the receiver wireless communication device of claim 18, as disclosed by Gulati in view of Xiao, wherein the one or more resources are identified at a per-resource-block (RB) resolution, as taught by Xiao. The motivation to do so would have been to have a receiver UE identify a resource block of a communication channel as being vulnerable by determining that the channel quality of the resource block fails to be above a quality threshold so that the receiver UE can perform de-interleaving based on lower priority parity bits being received during the resource blocks that fail to be above the quality threshold in order to improve decoding performance at a receiver.
Regarding claim 24, Gulati in view of Xiao disclose the receiver wireless communication device of claim 18.
Gulati fails to disclose wherein the one or more processors are further configured to cause the receiver wireless communication device to transmit a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold.
However, Xiao teaches wherein the one or more processors are further configured to cause the receiver wireless communication device to transmit a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold ([0038]-[0040] discloses a RAN transmitting a channel assignment to a UE that identifies an RBG, based on the received channel quality message that includes the bit map indicating which RBGs fail to exceed a channel quality threshold with a 0. A broadest reasonable assumption is that the RBG assignment by the RAN and transmitted to the UE is an RBG indicated with a 0 in the bit map (i.e. one that fails to exceed the channel quality threshold), that causes the UE to identify, using the RBG assignment communication, the assigned RBG.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the receiver wireless communication device of claim 18, as disclosed by Gulati in view of Xiao, wherein the one or more processors are further configured to cause the receiver wireless communication device to transmit a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold, as taught by Xiao. The motivation to do so would have been to have a receiver UE be able to identify a vulnerable RBG by receiving a communication transmitted from a RAN indicating an RBG, of a plurality of RBGs, as being a vulnerable RBG that fails to be above a channel quality threshold so that the receiver UE can perform interleaving that prioritizes lower priority parity bits to be transmitted on the communicated vulnerable RBG in order to improve decoding performance at a receiver.
Regarding claim 26, Gulati in view of Xiao disclose the receiver wireless communication device of claim 18.
Gulati fails to disclose wherein the one or more processors are further configured to cause the receiver wireless communication device to: receive a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold, and wherein the one or more processors, to cause the receiver wireless communication device to identify the one or more resources, are configured to cause the receiver wireless communication device to: identify the one or more resources using the information that identifies the one or more resources.
However, Xiao teaches wherein the one or more processors are further configured to cause the receiver wireless communication device to: receive a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold, and wherein the one or more processors, to cause the transmitter wireless communication device to identify the one or more resources, are configured to cause the receiver wireless communication device to: identify the one or more resources using the information that identifies the one or more resources (Fig 4 and [0025] & [0037]-[0038] discloses a RAN receiving reporting information concerning RB channel quality sent by a UE through a bit map that indicates a 1 when an RBG’s measured channel quality exceeds a threshold and a 0 when an RBG’s measured channel quality fails to exceed a threshold. [0040] discloses the RAN may then identify an RBG to assign to the UE using the bit map that identifies the RBG’s with measured quality failing to exceed a threshold by a 0 and RBG’s with measured quality exceeding a threshold by a 1.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the receiver wireless communication device of claim 18, as disclosed by Gulati in view of Xiao, wherein the one or more processors are further configured to cause the receiver wireless communication device to: receive a communication that includes information that identifies the one or more resources for which the channel characteristic fails to satisfy the threshold, and wherein the one or more processors, to cause the transmitter wireless communication device to identify the one or more resources, are configured to cause the receiver wireless communication device to: identify the one or more resources using the information that identifies the one or more resources, as taught by Xiao. The motivation to do so would have been to have a RAN be able to receive from a transmitter UE a bitmap indicating RBGs, of a plurality of RBGs, as being vulnerable RBGs in cases where the channel quality of the RBGs fail to be above a channel quality threshold so that the RAN can identify one or more RBGs using the bitmap as vulnerable and assign vulnerable RBGs to the transmitter UE so that the UE device can perform interleaving that prioritizes lower priority parity bits to be transmitted on the vulnerable RBGs that fail to be above the quality threshold in order to improve decoding performance at a receiver.
Regarding claim 28, Gulati in view of Xiao disclose the receiver wireless communication device of claim 18.

[0119] discloses that higher priority bits may include systematic bits. The set of higher priority systematic bits are shown in gray in fig 5 and the set of low priority parity bits are shown in white in fig 5. [0144] discloses that lower priority bits may be assigned to resources which are more likely to be unsuccessfully received (i.e. channel characteristic is vulnerable). Fig 6 & [0146]-[0150] disclose an example where a set of systematic bits (gray blocks in fig 6) and a second subset of parity bits (i.e. white blocks in fig 6) from the set of parity bits is mapped to resources identified as not vulnerable and labeled Er(nv). Note that the white blocks interleaved in the Er(nv) resources 630 represent a second subset of the low priority parity bits while a first subset of low priority parity bits are shown as white blocks interleaved in the Er(v) resources 635. Fig 12 & [0212] discloses a communications manager that supports the transmission methods to handle vulnerable resources discussed above including a decoding component 1255 that de-interleaves the interleaved plurality of coded bits discussed above.).

Gulati fails to disclose wherein the communication is transmitted according to a periodicity associated with the updating.

A broadest reasonable assumption is that the RBG assignment by the RAN and received by the UE is an RBG indicated with a 0 in the bit map (i.e. one that fails to exceed the channel quality threshold). By receiving the assigned RBGs from the RAN, the UE obtains a final bit string that indicates RGBs assigned by the RAN and are RBGs, in the plurality of RBGs, that fail to exceed the channel quality threshold.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the receiver wireless communication device of claim 18, as disclosed by Gulati in view of Xiao, wherein the one or more processors are further configured to cause the receiver wireless communication device to: generate an initial bit string that indicates whether each resource in the plurality of resources satisfies the threshold; and obtain a final bit string that indicates whether each resource in the plurality of resources satisfies the threshold, as taught by Xiao.

Regarding claim 23, Gulati in view of Xiao and Kim and Kwun disclose the receiver wireless communication device of claim 22.
Gulati fails to disclose wherein the set of CRC bits or parity bits is received in at least one of radio resource control (RRC) signaling, downlink control information (DCI), or uplink control information (UCI).
However, Wu further teaches wherein the set of CRC bits or parity bits is received in at least one of radio resource control (RRC) signaling (optional), downlink control information (DCI) ([0076] discloses transmitting a CRC as part of a DCI scrambled with a C-RNTI to a UE (i.e. UE receives the CRC as part of a DCI scrambled with a C-RNTI.), or uplink control information (UCI) (optional).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the receiver wireless communication device of claim 22, as disclosed by Gulati in view of Xiao and Kim and Kwun, wherein the set of CRC bits or parity bits is received in at least one of radio resource control (RRC) signaling, downlink control information (DCI), or uplink control information (UCI), as further taught by Wu. The motivation to do so would have been to have a receiver UE be able to receive a DCI with a bit string and CRC for the bit string in the payload of a DCI in order to detect and potentially correct errors in receiving the bit string to improve the likelihood of the receiver correctly receiving the bit string.
Claim 31 is rejected under 35 U.S.C. 103 as being unpatentable over Gulati et al. (US 20200266957)(herein after “Gulati”) in view of Xiao et al. (US 2009/0028260)(herein after “Xiao”), as applied to claim 30, and further in view of Kwon et al. (US 2021/0297139)(herein after “Kwon”).
Regarding claim 31, Gulati in view of Xiao disclose the method of claim 30.
Gulati fails to disclose but Kwon further teaches further comprising receiving a signal associated with the channel characteristic for the plurality of resources, wherein the signal is received on a periodic basis, and wherein identifying the one or more resources is based at least in part on the signal (Fig 8 & [0115]-[0116] discloses a UE receiving periodic CSI-RS signals that are used to monitor signal quality and determine when the signal quality is below a radio link quality threshold.).
Therefore, it would have been obvious to someone having ordinary skill in the art prior to the effective filing date of the claimed invention to have the receiver wireless communication device of claim 30, as disclosed by Gulati in view of Xiao, further comprising receiving a signal associated with the channel characteristic for the plurality of resources, wherein the signal is received on a periodic basis, and wherein identifying the one or more resources is based at least in part on the signal, as further taught by Kwon. The motivation to do so would have been to have a method for a receiver UE to periodically measure the channel quality of a plurality of symbols or resource blocks of consecutive slots of a communication channel and continually identify symbols or resource blocks of each slot as being vulnerable when the measured channel quality fails to be above a quality threshold so that the receiver UE can perform de-interleaving on each slot knowing that lower priority parity bits received have been prioritized to be on the symbols or during the resource blocks in each slot that fail to be above the quality threshold in order to continually improve decoding performance at a receiver across the consecutive slots.
