Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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.
Response to Arguments
Applicant's arguments filed 01 April 2026 concerning the rejection in view of Yu have been fully considered but they are not persuasive. Applicant argued Yu fails to disclose a first time-domain resource block bounded in time by one or more boundaries that are based on DMRS symbols as claimed. However, Examiner disagrees.
The broadest reasonable interpretation of a time-domain resource block is a set of symbols (specification of the instant application, para. 108). The broadest reasonable interpretation of a boundary of a set of symbols (i.e., boundary of a time-domain resource block) is a DMRS symbol location (specification, paras. 116-117) and the start and end of a slot (para. 121). Yu discloses DRMS symbols that are boundaries for non-DMRS symbols within a slot (figs. 2-3, 6-7, 8A and 8D; note: shaded areas are DMRS symbols). Therefore, Yu fairly teaches the invention as claimed.
Applicant’s arguments concerning the interpretation under 35 U.S.C. 112(f) have been fully considered but are not persuasive. Applicant argued the claims should not be interpreted under 35 U.S.C. 112(f). However, Examiner disagrees and reiterates the claim interpretation under 35 U.S.C. 112(f) of the non-final rejection although the claim interpretation is not repeated in this Office action.
The broadest reasonable interpretation of a processing system not invoking 35 U.S.C. 112(f) includes software and firmware (specification of the instant application, para. 281; note: software configured to later perform actions when executed on a processor: note: the processing system “may” include hardware and therefore is not required to include hardware). With the broadest reasonable interpretation of a processing system not invoking 35 U.S.C. 112 (f), the broadest reasonable interpretation of a network entity includes software and firmware. Under 35 U.S.C. 112(f) the claims have been interpreted to have the corresponding structure of the specification. If Applicant desires the claims to not invoke 35 U.S.C. 112(f) and to avoid a rejection under 35 U.S.C. 112(b), Examiner suggests reciting the processing system comprising a processor or device configured to perform the functions of the claims.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Claim Rejections - 35 USC § 103
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.
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.
Claim 2-4 and 27-28 are rejected under 35 U.S.C. 103 as being obvious over Yu in view of Gu (WO 2022/265626).
Regarding claims 2-4, Yu discloses receiving data during the first time-domain resource block (fig. 4, step S401; paras. 90 and 109-110; fig. 6; note: scheduled time-frequency resources of a PDSCH message) but fails to disclose the network entity of claim 1, wherein the processing system is configured to: cache the data received during the first time-domain resource block for subsequent processing, wherein, to demodulate the data, the processing system is configured to demodulate the data after a temporally last OFDM symbol of the first time-domain resource block, and wherein the processing system is configured to: perform a channel estimation procedure after a temporally last OFDM symbol of the first time-domain resource block, wherein the channel estimation procedure is based on a portion of the data received during the first time-domain resource block. However, Gu discloses buffering (caching) received data of a PDSCH for subsequent demodulation, where the demodulation is based on a channel estimation of a portion of PDSCH symbols (fig. 2; fig. 6, step S606; para. 70; paras. 27-28; note: all PDSCH symbols of a slot; paras. 47-48; step S618 and paras. 76-77; note: the channel estimation and demodulation processes start or continue after the last symbol is received in the slot as a more efficient or alternatively less efficient (conventional manner) of channel estimation and demodulation).
Therefore, it would have been obvious to one skilled in the art before the effective filing date of the claimed invention to cache data received during the first time-domain resource block for subsequent processing, demodulate data after a temporally last OFDM symbol of the first time-domain resource block, and perform a channel estimation procedure after a temporally last OFDM symbol of the first time-domain resource block, wherein the channel estimation procedure is based on a portion of the data received during the first time-domain resource block in the invention of Yu. The motivation to have the modification and/or well-known benefits of the modification include, but are not limited to, processing received data according to reference signals and channel estimation as is known in the art (Gu, figs. 2 and 6; para. 27-28, 47-48 and 76-77; MPEP 2143(I)(A)(B)(C)(D) - note: e.g., applying known techniques having predictable results).
Regarding claims 27-28, these limitations are rejected on the same ground as claims 2-3, respectively.
Claims 5 and 30 are rejected under 35 U.S.C. 103 as being obvious over Yu in view of Morozov et al. (US 2021/0006443).
Regarding claim 5, Yu discloses the network entity of claim 1, wherein the time-domain resource block pattern (fig. 5, step S501, DMRS pattern) defines a plurality of time-domain resource blocks (fig. 5, time units; fig. 6; paras. 72-73) that includes the first time-domain resource block, and wherein a resource block basis (figs. 2-3, 6-7 and 8A-8D; note: different amount of DMRS per slot; paras. 80, 148 and 151). However, Yu fails to disclose the DMRS as a codeword but Morozov discloses this feature (paras. 106 and 110; note: DMRS derived from a Gold code bit sequence). Therefore, it would have been obvious to one skilled in the art before the effective filing date of the claimed invention to have the DRMS as a codeword (Gold code) in the invention of Yu. The motivation to have the modification and/or well-known benefits of the modification include, but are not limited to, physically implementing reference signals as is known in the art (Morozov, paras. 106 and 110; MPEP 2143(I)(A)(B)(C)(D) - note: e.g., applying known techniques having predictable results).
Regarding claim 30, these limitations are rejected on the same ground as claim 5.
Claim 6-7 are rejected under 35 U.S.C. 103 as being obvious over Yu in view of Morozov as applied to claim 5 above, and in further view of Xiong et al. (US 2019/0053226).
Regarding claims 6-7, Yu fails to disclose the network entity of claim 5, wherein the mapping scheme is a time-first, frequency-second mapping scheme within each of the plurality of time-domain resource blocks and the network entity of claim 5, wherein the mapping scheme is a frequency-first, time-second mapping scheme within each of the plurality of time-domain resource blocks. However, Morozov discloses time-first and frequency-first DMRS mapping (para. 97, especially the third sentence) and Xiong discloses time-first and frequency-first mapping based on channel conditions (para. 63). Therefore, it would have been obvious to one skilled in the art before the effective filing date of the claimed invention to have the mapping scheme as a time-first, frequency-second mapping scheme within each of the plurality of time-domain resource blocks or the mapping scheme as a frequency-first, time-second mapping scheme within each of the plurality of time-domain resource blocks in the invention of Yu. The motivation to have the modification and/or well-known benefits of the modification include, but are not limited to, providing appropriate DMRS mapping as is known in the art (Morozov, para. 97 and Xiong, para. 63; MPEP 2143(I)(A)(B)(C)(D) - note: e.g., applying known techniques having predictable results).
Claim 8 is rejected under 35 U.S.C. 103 as being obvious over Yu in view of Morozov as applied to claim 5 above, and in further view of Zhang et al. (US 2021/0084623), Takeda et al. (US 2021/0410119) and Xiong et al. (US 2019/0053226).
Yu in view of Morozov fails to teach and make obvious the network entity of claim 5, wherein the plurality of time-domain resource blocks includes one or more time-domain resource blocks in each of multiple subbands. However, Zhang discloses time-domain resource block in multiple subbands (figs. 1a and 6; para. 172 and 199; note: DMRS for carriers assigned to a UE). Therefore, it would have been obvious to one skilled in the art before the effective filing date of the claimed invention to have the plurality of time-domain resource blocks include one or more time-domain resource blocks in each of multiple subbands in the invention of Yu in view of Morozov. The motivation to have the modification and/or well-known benefits of the modification include, but are not limited to, providing increased bandwidth or carrier aggregation for transmission as is well known in the art (Zhang, figs. 1a and 6, and paras. 3 (first sentence), 172 and 199; MPEP 2143(I)(A)(B)(C)(D) - note: e.g., applying known techniques having predictable results).
Further, Yu in view of the embodiment of Morozov and Zhang fails to teach and make obvious wherein the mapping scheme is a frequency-first, time-second mapping scheme within each of the plurality of time-domain resource blocks, and a subband-first, time-second mapping scheme between individual ones of the plurality of time-domain resource blocks. However, Morozov in another embodiment discloses frequency-first, time-second DMRS mapping for a time unit (para. 97, especially the third sentence; fig. 15a; paras. 159-160), Takeda discloses subband-first, time-second mapping for resources (fig. 6A and para 140, especially the last sentence) and Xiong discloses frequency-first mapping based on channel conditions (para. 63). Therefore, it would have been obvious to one skilled in the art before the effective filing date of the claimed invention to have the mapping scheme as a frequency-first, time-second mapping scheme within each of the plurality of time-domain resource blocks, and a subband-first (i.e., frequency-first over subbands of symbols of a time unit), time-second mapping scheme between individual ones of the plurality of time-domain resource blocks in the invention of Yu in view of the embodiment of Morozov and Zhang. The motivation to have the modification and/or well-known benefits of the modification include, but are not limited to, providing appropriate DMRS mapping as is known in the art (Morozov, para. 97; Takeda, fig. 6A and para 140; Xiong, para. 63; MPEP 2143(I)(A)(B)(C)(D) - note: e.g., applying known techniques having predictable results).
Claim 11 and 13-16 are rejected under 35 U.S.C. 103 as being obvious over Yu in view of Yang et al. (US 2016/0057753).
Regarding claims 11 and 13-16, Yu discloses DMRS at different symbols of a slot among several slots (figs. 2 and 6) but fails to disclose the network entity of claim 10, wherein the ending boundary is defined by a temporally last OFDM symbol of the first time-domain resource block being a DMRS symbol, the network entity of claim 9, wherein the first time-domain resource block and a temporally first of the one or more second time-domain resource blocks that immediately follows the first time-domain resource block are defined by a DMRS symbol that is either a temporally last OFDM symbol of the first time-domain resource block or a temporally first OFDM symbol of the temporally first of the one or more second time-domain resource blocks, the network entity of claim 9, wherein at least one of the first time-domain resource block or the one or more second time-domain resource blocks is defined to include a DMRS symbol that is a channel estimation source for one or more OFDM symbols in an adjacent time-domain resource block of the one or more second time-domain resource blocks, the network entity of claim 14, wherein the adjacent time-domain resource block is one of a temporally first or last of the one or more second time-domain resource blocks, and the network entity of claim 9, wherein one or more temporally last time-domain resource blocks of the one or more second time-domain resource blocks do not include DMRSs.
Yang discloses a DMRS at a last symbol of a slot for channel estimation of two adjacent slots (fig. 2; para. 25; note: for claim 13, alternatively, the last sentence of para. 25 describes a first symbol of second slot). Therefore, it would have been obvious to one skilled in the art before the effective filing date of the claimed invention to have the ending boundary defined by a temporally last OFDM symbol of the first time-domain resource block being a DMRS symbol, wherein the first time-domain resource block and a temporally first of the one or more second time-domain resource blocks that immediately follows the first time-domain resource block are defined by a DMRS symbol that is either a temporally last OFDM symbol of the first time-domain resource block or a temporally first OFDM symbol of the temporally first of the one or more second time-domain resource blocks, wherein at least one of the first time-domain resource block or the one or more second time-domain resource blocks is defined to include a DMRS symbol that is a channel estimation source for one or more OFDM symbols in an adjacent time-domain resource block of the one or more second time-domain resource blocks, wherein the adjacent time-domain resource block is one of a temporally first or last of the one or more second time-domain resource blocks, wherein one or more temporally last time-domain resource blocks of the one or more second time-domain resource blocks do not include demodulation reference signals (DMRSs) in the invention of Yu. The motivation to have the modification and/or well-known benefits of the modification include, but are not limited to, using one DMRS symbol for channel estimation of two time units (slots) as is known in the art (Yang, fig. 2 and para. 25; MPEP 2143(I)(A)(B)(C)(D) - note: e.g., applying known techniques having predictable results).
Claim 17 is rejected under 35 U.S.C. 103 as being obvious over Yu in view of Yang as applied to claim 16 above, and in further view of Nam et al. (US 2024/0172197).
Yu in view of Yang teaches and makes obvious a slot with 14 symbols (Yu, figs. 2 and 6) but fails to teach and make obvious the network entity of claim 16, wherein the one or more temporally last time-domain resource blocks each include communication network parameters (i.e., carrier spacing, number of subcarriers per PRB, network capacities, etc.) as is known in the art (Nam, fig. 12 and paras. 3, 99, 116 and 126; MPEP 2143(I)(A)(B)(C)(D) - note: e.g., applying known techniques having predictable results).
Claims 19 and 25 are rejected under 35 U.S.C. 103 as being obvious over Yu in view of Liu (US 2024/0163135).
Regarding claim 19, Yu fails to disclose the network entity of claim 1, wherein the processing system is configured to: report channel estimation time window duration information, wherein the second control information is based on the channel estimation time window duration information. However, Liu discloses a UE reporting a channel estimation duration (fig. 3; para. 50; note: capability of DMRS bundling across a number of slots or time range; para. 102; fig. 6) and control information is based on the channel estimation duration (paras. 97-98; paras. 42-44 and 47; note: DMRS timing and other parameters based on the capability). Therefore, it would have been obvious to one skilled in the art before the effective filing date of the claimed invention to report channel estimation time window duration information, wherein the second control information is based on the channel estimation time window duration information in the invention of Yu. The motivation to have the modification and/or well-known benefits of the modification include, but are not limited to, performing DMRS channel estimation over time periods based on capability as is known in the art (Liu, figs. 3 and 6, and paras. 42-44, 47 and 97-98; MPEP 2143(I)(A)(B)(C)(D) - note: e.g., applying known techniques having predictable results).
Regarding claim 25, Yu fails to disclose the first network entity of claim 20, wherein the second control information includes a DMRS pattern
