Office Action

§103
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 . Claims 1, 13, 15, 29, 30, 35, 36 and 41 are pending in this office action. Response to Arguments Applicant’s arguments with respect to the amendment 02/25/2026 filed have been considered but are moot in view of new grounds of rejection. 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, 13, 15, 29, 30, 35, 36 and 41 are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al (US 2024/0049346 A1) in view of R2-2103175 (HARQ related issues, 3GPP TSG-RAN2 #113bise) (cited in newly submitted IDS). Regarding claim 1, Liu teaches a method for starting a discontinuous reception (DRX) timer, performed by a terminal, comprising: starting the DRX timer according to a transmission type of at least one of an uplink transmission and/or or a downlink transmission (Liu: [0346]-[0351], starting HARQ RTT timer based on UE receiving PUSCH/uplink transmission resource; see also Table 1 and [0319] for DRX), wherein the transmission type comprises one of: an uplink transmission based on configured grant (CG), an uplink transmission based on physical downlink control channel (PDCCH) dynamic scheduling or a downlink transmission based on configured downlink assignment; determining the transmission type of the uplink transmission is the uplink transmission based on CG (Liu: [0207]; [0247], uplink transmission indicated by a configured grant or DCI). Liu does not explicitly disclose increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration. R2-2103175 teaches increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration (R2-2103175: Section 2.1 on Page 1; Proposal 1: increasing drx-HARQ-RTT-TimerUL length by an offset). It would have been obvious to a person having an ordinary skill in the art before the effective filling date of the claimed invention to modify the system of Liu by increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration as disclosed by R2-2103175 to provide a system downlink and uplink HARQ procedure (R2-2103175, section 2). Regarding claim 29, Liu teaches a communication device, comprising: a memory storing computer-executable instructions; and a processor connected to the memory, and configured to start a discontinuous reception (DRX) timer according to a transmission type of at least one of an uplink transmission or a downlink transmission (Liu: [0346]-[0351], starting HARQ RTT timer based on UE receiving PUSCH/uplink transmission resource; see also Table 1 and [0319] for DRX), wherein the transmission type comprises one of: an uplink transmission based on configured grant (CG), an uplink transmission based on physical downlink control channel (PDCCH) dynamic scheduling or a downlink transmission based on configured downlink assignment; determining the transmission type of the uplink transmission is the uplink transmission based on CG (Liu: [0207]; [0247], uplink transmission indicated by a configured grant or DCI). Liu does not explicitly disclose increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration. R2-2103175 teaches increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration (R2-2103175: Section 2.1 on Page 1; Proposal 1: increasing drx-HARQ-RTT-TimerUL length by an offset). It would have been obvious to a person having an ordinary skill in the art before the effective filling date of the claimed invention to modify the system of Liu by increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration as disclosed by R2-2103175 to provide a system downlink and uplink HARQ procedure (R2-2103175, section 2). Regarding claim 30, Liu teaches a computer non-transitory computer-readable storage medium having stored thereon computer executable instructions that, when executed by a processor of a communication device, cause the communication device to perform a method for starting a discontinuous reception (DRX) timer, the method comprising: starting the DRX timer according to a transmission type of at least one of an uplink transmission or a downlink transmission (Liu: [0346]-[0351], starting HARQ RTT timer based on UE receiving PUSCH/uplink transmission resource; see also Table 1 and [0319] for DRX), wherein the transmission type comprises one of: an uplink transmission based on configured grant (CG), an uplink transmission based on physical downlink control channel (PDCCH) dynamic scheduling or a downlink transmission based on configured downlink assignment; determining the transmission type of the uplink transmission is the uplink transmission based on CG (Liu: [0207]; [0247], uplink transmission indicated by a configured grant or DCI). Liu does not explicitly disclose increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration. R2-2103175 teaches increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration (R2-2103175: Section 2.1 on Page 1; Proposal 1: increasing drx-HARQ-RTT-TimerUL length by an offset). It would have been obvious to a person having an ordinary skill in the art before the effective filling date of the claimed invention to modify the system of Liu by increasing a timing period of an uplink DRX hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer by a predetermined duration as disclosed by R2-2103175 to provide a system downlink and uplink HARQ procedure (R2-2103175, section 2). Regarding claims 13 and 41, Liu teaches determining the transmission type of the uplink transmission is the uplink transmission based on PDCCH dynamic scheduling; wherein starting the DRX timer comprises: starting an uplink DRX retransmission according to a predetermined processing pattern (Liu: [0164], [0169], starting retransmission timer; [0033], receiving DCI for uplink scheduling). Regarding claims 15 and 36, Liu teaches wherein the predetermined processing pattern comprises one of: a pattern of starting the uplink DRX retransmission timer after receiving data on the PDCCH; a pattern of starting the uplink DRX retransmission timer from a first orthogonal frequency division multiplexing (OFDM) symbol after the uplink transmission ends (Liu: [0039], [0342], retransmission based on PUSCH transmission); a pattern of starting the uplink DRX retransmission timer from an initial orthogonal frequency division multiplexing (OFDM) symbol of the uplink transmission; [[or]] a pattern of starting the uplink DRX retransmission timer from a first orthogonal frequency division multiplexing (OFDM) symbol after a first retransmission of the uplink transmission; a pattern of starting the uplink DRX retransmission timer after generating a corresponding physical uplink shared channel (PUSCH) data packet according to a PDCCH indication; or a pattern of starting the uplink DRX retransmission timer after a processing delay when data on the PDCCH are received. Regarding claim 35, Liu teaches wherein the processor is further configured to: determine the transmission type of the uplink transmission is the uplink transmission based on PDCCH dynamic scheduling; and start an uplink DRX retransmission timer according to a predetermined processing pattern (Liu: [0164], [0169], starting retransmission timer; [0033], receiving DCI for uplink scheduling). Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
