DETAILED ACTION
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 .
Response to Amendment
Claims 1-2, 13-14, and 16-20 have been amended.
Claims 1-11, 13-14, and 16-21 are pending.
Response to Arguments
Applicant's arguments filed on 05/11/2026 have been fully considered but they are not persuasive.
In the remarks, the Applicant argues in substance that:
The Applicant argues that the cited references fail to disclose or suggest “wherein value 0 is used for the DRX HARQ RTT timer SL in case physical uplink control channel (PUCCH) configuration used for HARQ feedback reporting is not configured and the SL resource pool is not configured with physical sidelink feedback channel (PSFCH)" as recited in Applicant's claim 1, (see Remarks pgs. 1-6)
In response, Examiner respectfully disagrees. Applicant is reminded that claims must be given their broadest reasonable interpretation. The Applicant argued “InterDigital still allows non-zero values even under HARQ feedback disabled conditions” (See Remarks pg. 4). Based on the current language of the claimed limitation, the claim requires that value 0 is used, and does not require that only value 0 be used or that non-zero values be excluded. InterDigital (Section 2.1, pg. 1) discloses “When HARQ feedback is disabled, either zero value or non-zero value can be configured for the HARQ RTT timer”. InterDigital (Proposal 1, pg. 2) further discloses “Proposal 1: For HARQ feedback disabled or PSFCH not configured…Since the retransmission may come in the subsequent slot, and a HARQ RTT timer of zero should be possible”. Thus, under BRI, the cited references meet the scope of the claimed limitation as currently presented.
b. The Applicant further argues that InterDigital teaches away from the argued limitation stated above. (see Remarks pgs. 3-5)
In response, Examiner respectfully disagrees. Applicant states that “InterDigital teaches away from enforcing a fixed value of zero” (see Remarks pgs. 4-5). InterDigital (Section 2.1, pg. 1) discloses “When HARQ feedback is disabled, either zero value or non-zero value can be configured for the HARQ RTT timer”. InterDigital (Proposal 1, pg. 2) merely explains why separate timer configurations are used for different operating conditions. It does not discourage a zero-valued timer. Based on the current language of the argued limitation, the claim requires that value 0 is used, and does not require that only value 0 be used or that non-zero values be excluded. Thus, under BRI, the cited references meet the scope of the claimed limitation as currently presented. As such, the rejections of record are maintained.
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.
Claims 1-2, 8-11, 14, 16 are rejected under 35 U.S.C. 103 as being unpatentable over Tseng et al. (US 20230066448, hereinafter, “Tseng”) in view of “Remaining Aspects on SL DRX” published on January 2022 by InterDigital, hereinafter, “InterDigital”, provided in the IDS filed on 08/30/2023 by the applicant).
Claim 1. Tseng teaches: A method, comprising: - See Fig. 1, 3
obtaining, by a first device, a discontinuous reception (DRX) configuration - See Fig. 4, ¶ [0009], (“UE to receive at least one SL-Discontinuous Reception (SL-DRX) configuration and a plurality of SL resource pool configurations configured on the first UE”) for physical downlink control channel (PDCCH) monitoring, - See Fig. 4, ¶ [0034], (“the UE may be configured with a DRX functionality that controls the UE's Physical Downlink Control Channel (PDCCH) monitoring activity.”) including a DRX hybrid automatic repeat request (HARQ) round trip time (RTT) timer sidelink (SL); - in ¶ [0096], (“If SL-DRX is configured…the RRC entity may control the SL-DRX operation by configuring the following parameters:…¶ [0105] drx-HARQ-RTT-TimerSL_Rx (e.g., for each SL-HARQ reception process in which the UE needs to transmit SL-HARQ feedback information to the associated SL-Tx UE”)
obtaining, by the first device, configuration information of an SL resource pool; - in ¶ [0009], (“UE to receive at least one SL-Discontinuous Reception (SL-DRX) configuration and a plurality of SL resource pool configurations configured on the first UE”) and
starting, by the first device, a timer based on the DRX HARQ RTT timerSL, in ¶ [0111], (“when the SL-DRX is configured, the MAC entity may:… 2> start the drx-HARQ-RTT-TimerSL_Tx for the corresponding SL-HARQ process…1> if a drx-HARQ-RTT-TimerSL_Rx expires…3> start the drx-RetransmissionTimerSL_Rx for the corresponding SL- HARQ process”)
wherein the DRX HARQ RTT timer SL is a minimum duration before an SL retransmission grant is expected by the first device, - in ¶ [0106], (“drx-HARQ-RTT-TimerSL_Tx…this may be the minimum duration before an SL-HARQ retransmission grant is expected by the MAC entity.”) and
Tseng does not explicitly teach:
wherein, value 0 is used for the DRX HARQ RTT timer SL in case physical uplink control channel (PUCCH) configuration used for HARQ feedback reporting is not configured and the SL resource pool is not configured with physical sidelink feedback channel (PSFCH).
However, InterDigital teaches:
wherein, value 0 is used for the DRX HARQ RTT timer SL - See pg. 1, Section 2.1, (“20: The value(s) of the SL HARQ RTT Timer, when explicitly configured…is determined by UE or NW implementation…5: When HARQ feedback is disabled, either zero value or non-zero value can be configured for the HARQ RTT timer if the resource assignment information is not present.”) in case physical uplink control channel (PUCCH) configuration used for HARQ feedback reporting is not configured and the SL resource pool is not configured with physical sidelink feedback channel (PSFCH). - See pg. 2, Section 2.1, (“Proposal 1: For HARQ feedback disabled or PSFCH not configured…Since the retransmission may come in the subsequent slot, and a HARQ RTT timer of zero should be possible…Proposal 2: Two separate HARQ RTT timers are configured and used by the UE for HARQ enabled transmissions versus HARQ disabled/PSFCH not configured.”, HARQ RTT timer can be set to zero when both HARQ is disabled (PUCCH configuration used for HARQ feedback reporting is not configured) and PSFCH is not configured)
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Tseng with InterDigital to include value 0 is used for the DRX HARQ RTT timer SL when PUCCH configuration used for HARQ feedback reporting and SL resource pool configuration with a PSFCH are not configured, as taught by InterDigital. One of ordinary skill in the art would have been motivated to make this modification to avoid unnecessary deactivation of the HARQ RTT timer, as suggested by InterDigital, While the operation of the HARQ RTT timer is clear for HARQ enabled transmissions, the case of HARQ disabled transmissions (as well as for PSFCH not configured), the starting time has not been discussed. - See pg. 2, lines 3-4
Claim 2. Combination of Tseng and InterDigital teaches The method of claim 1, - refer to the indicated claim for reference(s).
Tseng teaches:
wherein the SL resource pool includes at least one of at least one first resource and at least one second resource, - in ¶ [0172], (“The available SL resources may include all of SL reception resource pools.”) wherein the at least one first resource includes at least one of at least configured grant (CG) type 1 resource and at least one CG type 2 resource, - in ¶ [0231], (“the SL resource pool configurations may include at least one of…an SL resource pool configuration for SL discovery message transmission, an SL dynamic grant (i.e. one or more SL dynamic grants), a Type-1 SL configured grant (i.e. one or more Type-1 SL configured grants), a Type-2 SL configured grant (i.e. one or more Type-2 SL configured grants)”) and wherein the at least one second resource includes at least one dynamic grant (DG) resource. - in ¶ [0231], (“the SL resource pool configurations may include at least one of…an SL resource pool configuration for SL discovery message transmission, an SL dynamic grant (i.e. one or more SL dynamic grants)”)
Claim 8. Combination of Tseng and InterDigital teaches The method of claim 1, - refer to the indicated claim for reference(s).
Tseng teaches:
further comprising: starting a DRX retransmission timer after an expiry of the timer based on the DRX HARQ RTT timer SL, - in ¶ [0111], (“1> if a drx-HARQ-RTT-TimerSL_Rx expires:…3> start the drx-RetransmissionTimerSL_Rx for the corresponding SL-HARQ process in the first symbol after the expiry of drx-HARQ-RTT-TimerSL_Rx. 1>”) wherein the DRX configuration further includes information related to a DRX retransmission timer, - in ¶ [0096], (“If SL-DRX is configured…the RRC entity may control the SL-DRX operation by configuring the following parameters:…¶ [0100] drx-RetransmissionTimerSL_Rx”) and wherein the DRX retransmission timer is a maximum duration until the SL retransmission grant is received. - in ¶ [0100], (“drx-RetransmissionTimerSL_Rx…this may be the maximum duration until an SL retransmission is received;”)
Claim 9. Combination of Tseng and InterDigital teaches The method of claim 8, - refer to the indicated claim for reference(s).
Tseng teaches:
wherein the timer based on the DRX HARQ RTT timer SL and the DRX retransmission timer are timers configured per HARQ process. - in ¶ [0105 - 0106], (“drx-RetransmissionTimerSL_Rx (e.g., for each SL-HARQ reception process in which the UE needs to transmit SL-HARQ feedback information…drx-HARQ-RTT-TimerSL_Tx (e.g., per SL-HARQ transmission process in which the UE needs to re-transmit…”)
Claim 10. Combination of Tseng and InterDigital teaches The method of claim 1, - refer to the indicated claim for reference(s).
Tseng teaches:
wherein the SL retransmission grant is received on a PDCCH – in ¶ [0106], (“drx-RetransmissionTimerSL_Rx (e.g., for each SL-HARQ reception process in which the UE needs to transmit SL-HARQ feedback information to the associated SL-Tx UE): this may be the maximum duration until an SL retransmission is received… SL-HARQ retransmission grant is expected by the MAC entity.”); ¶ [0034], (“the UE may be configured with a DRX functionality that controls the UE's Physical Downlink Control Channel (PDCCH) monitoring activity.”) and wherein the SL retransmission grant is used to determine one or more SL resources for retransmission. – in ¶ [0106], (“drx-RetransmissionTimerSL_Rx…this may be the maximum duration until an SL retransmission is received… SL-HARQ retransmission grant is expected by the MAC entity.”); ¶ [0080], (“The UE may request SL resources from the eNB…The eNB schedules dedicated SL resource for the UE to transmit SCI and SL data.”)
Claim 11. Combination of Tseng and InterDigital teaches The method of claim 1, - refer to the indicated claim for reference(s).
InterDigital further teaches:
wherein, based on that the PUCCH configuration is not configured, the timer based on the DRX HARQ RTT timer SL is started. - See pg. 2, Section 2.1, (“Proposal 1: For HARQ feedback disabled or PSFCH not configured, the RX UE starts the HARQ RTT timer upon reception of SCI.”)
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Tseng with InterDigital to include the HARQ RTT timer is started based on the PUCCH configuration not being configured, as taught by InterDigital. One of ordinary skill in the art would have been motivated to make this modification to avoid unnecessary deactivation of the HARQ RTT timer, as suggested by InterDigital, While the operation of the HARQ RTT timer is clear for HARQ enabled transmissions, the case of HARQ disabled transmissions (as well as for PSFCH not configured), the starting time has not been discussed. - See pg. 2
Claim 14 is the apparatus claim corresponding to the method claim of Claim 1 and is rejected under the same rationale as Claim 1 since they recite nearly identical limitations.
Claim 16 is rejected under the same rationale as Claim 2 since they recite nearly identical limitations.
Claims 3-7, 13, 17-20 are rejected under 35 U.S.C. 103 as being unpatentable over Tseng et al. (US 20230066448, hereinafter, “Tseng”) in view of “Remaining Aspects on SL DRX” published on January 2022 by InterDigital, hereinafter, “InterDigital”, provided in the IDS filed on 08/30/2023 by the applicant), and further in view of Freda et al. (US 20240163962, hereinafter, “Freda”).
Claim 3. Combination of Tseng and InterDigital teaches The method of claim 2, - refer to the indicated claim for reference(s).
Tseng teaches:
further comprising: receiving an SL grant for determining one or more SL resources through a PDCCH, - in ¶ [0176], (“the UE may still monitor the PDCCHs (or search spaces/CORESETs configured for SL configured grant(s) (de) activations) (e.g., for SL configured grant activation/de-activation from the serving RAN) during the (SL-DRX) Active Time”)
Tseng does not explicitly teach:
wherein, based on that the PUCCH configuration is not configured, the timer based on the DRX HARQ RTT timer SL is started after the one or more SL resources.
However, Freda teaches:
wherein, based on that the PUCCH configuration is not configured, - in ¶ [0132], (“For HARQ disabled transmissions, the RX WTRU (e.g., WTRU 102) may not transmit HARQ feedback on PSFCH.”) the timer based on the DRX HARQ RTT timer SL is started after the one or more SL resources.– See Fig. 4, ¶ [0138], (“A RX WTRU (e.g., WTRU 102) may start a HARQ RTT timer at some time instant (e.g., the slot following, or a number of specified slots following) relative to any of: [0139] the reception of SCI and/or data for that HARQ process…[0146] directly start the retransmission timer for the HARQ process.”); ¶ [0131], (“a single SCI may indicate resources for an additional transmission and/or further retransmissions for the HARQ process”)
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Tseng and InterDigital with Freda to include based on the PUCCH configuration is not configured, the timer based on the DRX HARQ RTT timer SL is started after the one or more SL resources, as taught by Freda. One of ordinary skill in the art would have been motivated to make this modification to result in reliable transmission by ensuring proper HARQ RTT timer operation, as suggested by Freda, in sidelink, In SL communication, there are a number of differences with Uu scheduling which may create problems with the approach of DRX concept…the WTRU may not (e.g., always) transmit PSFCH for different reasons (for example, HARQ disable. - ¶ [0130]
Claim 4. Combination of Tseng, InterDigital, and Freda teaches The method of claim 3, - refer to the indicated claim for reference(s).
Freda further teaches:
wherein, based on that (i) the PUCCH configuration is not configured, - in ¶ [0132], (“For HARQ disabled transmissions, the RX WTRU (e.g., WTRU 102) may not transmit HARQ feedback on PSFCH.”, Since HARQ is disabled, no uplink channel is used (eq. PUCCH configuration is not configured)) and (ii) the one or more SL resources are determined, - in ¶ [0131], (“Specifically, in SL, a single SCI may indicate resources for an additional transmission and/or further retransmissions for the HARQ process, where the transmission and/or the retransmissions can be non-contiguous in time.”) the timer based on the DRX HARQ RTT timer SL is started after the one or more SL resources. - in ¶ [0138], (“A RX WTRU (e.g., WTRU 102) may start a HARQ RTT timer…relative to any of: [0139] the reception of SCI and/or data for that HARQ process…[0144] a (pre)configured or pre-define time following the reception of SCI”); ¶ [0131], (“a single SCI may indicate resources for an additional transmission and/or further retransmissions for the HARQ process”, SCI determines one or more SL resources and the timer is started following reception of SCI.)

One of ordinary skill in the art would have been motivated to make this modification to result in reliable transmission by ensuring proper timer operation, as suggested by Freda, The TX WTRU (e.g., WTRU 102) may use a related (but different) value of such timers to compensate for the delay in performing transmission, and/or performing reliable transmission…the TX WTRU (e.g., WTRU 102) may be configured with…a HARQ RTT timer. - ¶ [0639 - 0640]
