Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of pre-AIA 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless -
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
Claims 53, 55-60, 65 and 67-72 are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Qualcomm Incorporated (R1-1911110 “Physical Layer Procedures for Sidelink”, of IDS, hereinafter ‘QUALCOMM’).
Regarding claim 53, QUALCOMM teaches a first apparatus (
Page 1 Section 2.1 PSFCH Resource Management
Paragraph 1:
UEs sending ACK feedbacks) comprising:
at least one processor; and at least one memory, the at least one memory storing instructions, that when executed by the at least one processor (
Page 1 Section 2.1 PSFCH Resource Management
Paragraph 1:
UEs sending ACK feedbacks), cause the first apparatus to:

Second sub-bullet:
….. different RX UEs for HARQ feedback of the same PSSCH transmission);
transmit a first feedback in response to the transmission (

Second sub-bullet:
For groupcast HARQ feedback Option 2, support CDM and FDM between PSFCH resources used by different RX UEs for HARQ feedback of the same PSSCH transmission);
wherein the first apparatus uses a plurality of resource blocks to form a Physical Sidelink Feedback Channel (PSFCH) transmission for the first feedback (
Page 1 Section 2.1
Paragraph 5:
A compromised implementation for Option 2 feedback multiplexing is FDM+CDM. Specifically, two HARQ feedback frequency resources are reserved for a data transmission, one for ACK and the other one for NACK; NACK (or ACK) feedbacks from multiple receivers are CDM multiplexed, e.g., different cyclic shifts can be applied to the NACK (or ACK) sequence. This further clarifies the following agreement concluded from in RAN1 email discussions.

Second sub-bullet cited above,
Page 2 Paragraph 3:
From PSFCH resource management perspective, to accommodate feedbacks from different UEs for different feedback options and cast types, a straightforward solution is to configure two HARQ resource sets with different frequency locations in a PSFCH slot. One of the resource sets is used for NACK transmission (NACK for both feedback options, as well as NACK for unicast transmission), the other resource set is used for ACK transmission (ACK for unicast and ACK for feedback Option 2). Take N=2, K=2, BW=100 RBs, Subchannel=10 RBs as an example.);
wherein the plurality of resource blocks comprises a first resource block, and at least one second resource block (

wherein a second resource block in the at least one second resource block is configured to be reusable for the first feedback, and for a second feedback of a second apparatus (

Specifically, two HARQ feedback frequency resources are reserved for a data transmission, one for ACK and the other one for NACK; NACK (or ACK) feedbacks from multiple receivers are CDM multiplexed, e.g., different cyclic shifts can be applied to the NACK (or ACK) sequence. This further clarifies the following agreement concluded from in RAN1 email discussions.

Second sub-bullet cited above,
Page 2 Proposal 1b:
For feedbacks acknowledging the same PSSCH transmission in Option 2: ACK and NACK are FDM multiplexed; multiple ACK (or NACK) from different receivers are CDM multiplexed.
(Construed one or second of the two resource block of PSFCH is shared or reused by different receivers or first UE apparatus and second UE apparatus for ACK or NACK feedback transmission, the respective feedback from each UE apparatus are having different cyclic shift for CDM multiplexing on the shared PSFCH)).
Regarding claim 65, the claim is interpreted mutatis mutandis of claim 53 and rejected for the same reason as set forth for claim 53.
Regarding claim 72, QUALCOMM teaches a third apparatus (
Page 1 Section 2.1 Paragraph 2:
transmitter UE to differentiate feedbacks from different receivers) comprising:
at least one processor; and at least one memory, the at least one memory storing instructions, that when executed by the at least one processor (
Page 1 Section 2.1 Paragraph 2:
transmitter UE).
Further claim 72 is interpreted mutatis mutandis of claim 53 and rejected for the same reason as set forth for claim 53.
Regarding claim 55, QUALCOMM teaches the first apparatus according to claim 53,
wherein the second feedback is transmitted by the second apparatus using a plurality of resource blocks comprising a third resource block, and at least one fourth resource block, wherein the first resource block for the first feedback is in a first PSFCH subchannel, wherein the second resource block for the first feedback is in a second PSFCH subchannel (
Page 2 Paragraph 3:
From PSFCH resource management perspective, to accommodate feedbacks from different UEs for different feedback options and cast types, a straightforward solution is to configure two HARQ resource sets with different frequency locations in a PSFCH slot. One of the resource sets is used for NACK transmission (NACK for both feedback options, as well as NACK for unicast transmission), the other resource set is used for ACK transmission (ACK for unicast and ACK for feedback Option 2). Take N=2, K=2, BW=100 RBs, Subchannel=10 RBs as an example. There would be totally 20 data transmissions in a feedback period (at most). Based on the discussed approach, 40 PSFCH resources are needed in a PSFCH slot; it is obvious that a feedback slot can provide sufficient resources for PSFCH given the 1 or 2 RBs PSFCH transmission bandwidth.
Proposal 1c: Two feedback resource sets are configured in PSFCH slots, one for NACK transmission, the other one for ACK transmission.

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 of this title, 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.
Claims 54, 61 and 66 are rejected under AIA 35 U.S.C. 103 as being unpatentable over Qualcomm Incorporated (R1-1911110 “Physical Layer Procedures for Sidelink”, of IDS, hereinafter ‘QUALCOMM’) in view of Wu et al. (US 20200351032 A1, hereinafter ‘WU’).
Regarding claim 54, QUALCOMM teaches the first apparatus according to claim 53,
wherein the transmission is a Physical Sidelink Shared Channel (PSSCH) transmission (
Page 2 Proposal 4
Second sub-bullet:
….. different RX UEs for HARQ feedback of the same PSSCH transmission);
wherein a resource location of the plurality of resource blocks is derived from a resource location of the PSSCH transmission and/or the PSCCH transmission (
Page 2 Paragraph 6:
in a feedback period, a PSFCH resource is uniquely determined by location of the PSSCH transmission; the location of a PSSCH transmission is determined by the ending slot location and starting subchannel location of the PSSCH.
Proposal 1d:
HARQ feedbacks acknowledging PSSCH transmissions having different locations (either frequency location or time location) are FDM multiplexed.).
QUALCOMM does not explicitly disclose wherein the transmission is a Physical Sidelink Shared Channel (PSSCH) transmission, together with a Physical Sidelink Control Channel (PSCCH) transmission.
In an analogous art, WU teaches wherein the transmission is a Physical Sidelink Shared Channel (PSSCH) transmission, together with a Physical Sidelink Control Channel (PSCCH) transmission (
Fig. 5, [0109] FIG. 5 illustrates a schematic diagram of a second HARQ feedback mode according to an embodiment of the disclosure.
[0110] The groupcast transmission in the sidelink communication system means that the sidelink transmission is received and decoded by a group of RX UEs, that is, the number of RX UEs is at least more than one. In the groupcast transmission, the Sidelink Control Information (SCI) carried by the PSCCH includes indication information of a destination group ID, and all UEs belonging to the destination group ID should receive and decode the PSSCH corresponding to the SCI.)
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to take the technique of sidelink HARQ feedback wireless communication system for a PSCCH with corresponding PSSCH reception of WU to physical layer procedures for sidelink of QUALCOMM for an advantage of a method providing improvement of the reliability and the transmission efficiency of sidelink data transmission according to determined feedback mode (WU: [0011, 0074]).
Regarding claim 66, the claim is interpreted and rejected for the same reason as set forth for claim 54.
Regarding claim 61, QUALCOMM teaches the first apparatus according to claim 53,
QUALCOMM does not explicitly disclose wherein a power of the at least one second resource block and/or a number of the at least one second resource block are controlled, based on at least one of:
a number of PSCCH/PSSCH transmissions detected by the first apparatus, and/or a power required by a HARQ transmission, and/or a resource pool occupancy level.
WU teaches wherein a power of the at least one second resource block and/or a number of the at least one second resource block are controlled, based on at least one of:
a number of PSCCH/PSSCH transmissions detected by the first apparatus, and/or a power required by a HARQ transmission, and/or a resource pool occupancy level (
[0082] In an NR V2X system, there are a plurality of sub-channels in one slot, and an RX UE attempts to receive and decode PSCCHs/PSSCHs on each sub-channel in one slot, that is, the RX UE may simultaneously receive and decode a plurality of unicast PSCCHs/PSSCHs and/or groupcast PSCCHs/PSSCHs from different TX UEs in one slot. When these unicast and/or groupcast transmissions are configured to use the HARQ feedback function, the RX UE may face a problem of simultaneously transmitting the plurality of PSFCHs in one slot. Resources of the plurality of PSFCHs may be Frequency Division Multiplexing (FDM) and/or Code Division Multiplexing (CDM), and simultaneously transmitting a plurality of PSFCHs has certain requirements on the hardware capabilities of the RX UE. In addition, simultaneously transmitting a plurality of PSFCHs also affects the transmission reliability of the PSFCH, since the maximum transmitting power of the RX UE is fixed, and when a plurality of PSFCHs are simultaneously transmitted, a maximum transmitting power for each PSFCH has to be reduced, and thus the reliability of PSFCH transmission is affected.
[0084] As an example, the RX UE performs open-loop power control based on a sidelink pathloss and/or based on a downlink pathloss on a PSFCH, and the number of PSFCHs actually transmitted by the RX UE in the same slot is affected by a total transmitting power, and the RX UE calculates the open-loop transmitting power of each PSFCH based on a loop power control algorithm. If the total transmitting power of the plurality of PSFCHs does not exceed a maximum rated transmitting power of the RX UE, the RX UE may simultaneously transmit the plurality of PSFCHs in the same slot. and if the total transmitting power of the plurality of PSFCHs exceeds the maximum rated transmitting power of the RX UE, the RX UE may transmit the PSFCHs using at least one of the following methods:
See also [0085] ).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to take the technique of sidelink HARQ feedback wireless communication system for a PSCCH with corresponding PSSCH reception of WU to physical layer procedures for sidelink of QUALCOMM for an advantage of a method providing improvement of the reliability and the transmission efficiency of sidelink data transmission according to determined feedback mode (WU: [0011, 0074]).
Claim 62 are rejected under AIA 35 U.S.C. 103 as being unpatentable over Qualcomm Incorporated (R1-1911110 “Physical Layer Procedures for Sidelink”, of IDS, hereinafter ‘QUALCOMM’) in view of Hwang et al. (US 20220132471 A1, hereinafter ‘HWANG’).
Regarding claim 62, QUALCOMM teaches the first apparatus according to claim 53,
QUALCOMM does not explicitly disclose wherein a guard band is configured beside the second resource block.
In an analogous art, HWANG teaches wherein a guard band is configured beside the second resource block (
Fig. 16, [0160] Referring to FIG. 16, an interval N RBs may be secured between the unicast PSFCH and the common PSFCH, and thus the IBE problem between PSFCH resources may be alleviated.
[0164] Based on an embodiment of the present disclosure, if PSFCH resources are divided between PSSCH receiving UEs in groupcast, the transmitting UE may receive HARQ feedback through a plurality of PSFCH resources. In the PSFCH resource set, N RB intervals may exist between a PSFCH resource corresponding to unicast and a PSFCH resource corresponding to groupcast in which PSFCH resources are divided between a plurality of PSSCH receiving UEs. That is, the transmitting UE may receive or have different offsets between PSFCH resource sets based on a cast type and/or whether a PSFCH resource are shared.).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to take the technique for using RB interval or a guardband among PSFCH resources in NR V2X of HWANG to physical layer procedures for sidelink of QUALCOMM for an advantage of a method for alleviating an interference problem from inter-band emission (IBE) (HWANG: [0144, 0160]).
Claim 64 are rejected under AIA 35 U.S.C. 103 as being unpatentable over Qualcomm Incorporated (R1-1911110 “Physical Layer Procedures for Sidelink”, of IDS, hereinafter ‘QUALCOMM’) in view of Liu et al. (US 20250287401 A1 with priority of JP 2022-072435, hereinafter ‘LIU’).
Regarding claim 64, QUALCOMM teaches the first apparatus according to claim 53,
wherein the feedback is a Hybrid Acknowledge Request feedback; and/or wherein the first apparatus comprises a user equipment, UE (
Page 2 Proposal 4
For implicit mechanism for PSFCH resource determination,
…
For groupcast HARQ feedback Option 2, support CDM and FDM between PSFCH resources used by different RX UEs for HARQ feedback of the same PSSCH transmission).
QUALCOMM does not explicitly disclose wherein the first apparatus comprises a user equipment, UE, using a side link unlicensed resource.
In an analogous art, LIU teaches wherein the first apparatus comprises a user equipment, UE, using a side link unlicensed resource (
[0004] the present invention, supporting HARQ feedback transmission and reception on PSFCH over unlicensed spectrum, which may improve the communication flexibility and/or efficiency.
[0021] A communication method by a user equipment (UE) is described. The method includes transmitting, to another UE, a physical sidelink shared channel (PSSCH) with interlaced transmission, the PSSCH being allocated with one or more resource block (RB) sets and one or more interlaces in frequency domain; and determining, a physical sidelink feedback channel (PSFCH) resource for a HARQ feedback reception in response to the transmission of the PSSCH, wherein the PSFCH resource in frequency domain corresponds to an interlace and an RB set ).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to take the technique for HARQ feedback transmission and reception on PSFCH over unlicensed spectrum of LIU to physical layer procedures for sidelink of QUALCOMM for an advantage of a method for improving the communication flexibility and/or efficiency (LIU: [0004]).
