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 1-3, 5, 8-10, 12 and 15-18 are rejected under 35 U.S.C. 103 as being unpatentable over Wang et al (US 2023/0413286 A1) in view of Lei (US 2024/0340117 A1).
Regarding claim 1, Wang teaches a method for communication, comprising:
determining, by a terminal device, that a first physical downlink control channel (PDCCH) is a group-common physical downlink control channel (GC-PDCCH) (Wang: Fig. 1; [0037], UE receiving PDCCH for group of UE, i.e. GC-PDCCH for multicast transmission on PDSCH using scrambling by G-RNTI); and
determining, by the terminal device, that data carried on a first physical downlink shared channel (PDSCH) scheduled by the first PDCCH is new multicast data initially transmitted (Wang: Fig. 1; [0053], [0066], [0100], determining whether a transmission is an initial/new transmission based on scrambling by G-RNTI).
Wang does not explicitly disclose after determining, by the terminal device, that the first PDCCH is the GC-PDCCH, receiving, by the terminal device, a third PDCCH, wherein the third PDCCH is a user equipment (UE)-specific PDCCH, and a third hybrid automatic repeat request (HARQ) process identifier (HPID) carried on the third PDCCH is the same with a first HPID; and determining, by the terminal device based on a third NDI carried on the third PDCCH and a first NDI, whether data carried on a third PDSCH scheduled by the third PDCCH is the multicast data retransmitted or new unicast data initially transmitted.
Lei teaches after determining, by the terminal device, that the first PDCCH is the GC-PDCCH, receiving, by the terminal device, a third PDCCH, wherein the third PDCCH is a user equipment (UE)-specific PDCCH, and a third hybrid automatic repeat request (HARQ) process identifier (HPID) carried on the third PDCCH is the same with a first HPID; and determining, by the terminal device based on a third NDI carried on the third PDCCH and a first NDI, whether data carried on a third PDSCH scheduled by the third PDCCH is the multicast data retransmitted or new unicast data initially transmitted (Lei: Fig. 2; [0031], a PTM is first transmitted with GC- PDCCH; then a PTP based retransmission, in which the cyclic redundancy check (CRC) of the DCI is scrambled by a UE-specific RNTI (e.g., C-RNTI), can be used for scheduling the retransmission of the TB, with the same HARQ process ID and an untoggled NDI).
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 Wang wherein after determining, by the terminal device, that the first PDCCH is the GC-PDCCH, receiving, by the terminal device, a third PDCCH, wherein the third PDCCH is a user equipment (UE)-specific PDCCH, and a third hybrid automatic repeat request (HARQ) process identifier (HPID) carried on the third PDCCH is the same with a first HPID; and determining, by the terminal device based on a third NDI carried on the third PDCCH and a first NDI, whether data carried on a third PDSCH scheduled by the third PDCCH is the multicast data retransmitted or new unicast data initially transmitted as disclosed by Lei to provide a system for error case handling during multicast HARQ retransmission (Lei: Abstract).
Regarding claim 8, Wang teaches a terminal device, comprising: a processor; and a memory for storing a program, wherein the processor is configured to invoke the program in the memory to:
determine that a first physical downlink control channel (PDCCH) is a group-common physical downlink control channel (GC-PDCCH) (Wang: Fig. 1; [0037], UE receiving PDCCH for group of UE, i.e. GC-PDCCH for multicast transmission on PDSCH using scrambling by G-RNTI); and
determine that data carried on a first physical downlink shared channel (PDSCH) scheduled by the first PDCCH is new multicast data initially transmitted (Wang: Fig. 1; [0053], [0066], [0100], determining whether a transmission is an initial/new transmission based on scrambling by G-RNTI).
Wang does not explicitly disclose wherein the terminal device further comprises :a transceiver, configured to receive a third PDCCH, wherein the third PDCCH is a user equipment (UE)-specific PDCCH, and a third hybrid automatic repeat request (HARQ) process identifier (HPID) carried on the third PDCCH is the same with a first HPID, wherein the processor is further configured to determine, based on a third NDI carried on the third PDCCH and a first NDI, whether data carried on a third PDSCH scheduled by the third PDCCH is the multicast data retransmitted or new unicast data initially transmitted.
Lei teaches wherein the terminal device further comprises :a transceiver, configured to receive a third PDCCH, wherein the third PDCCH is a user equipment (UE)-specific PDCCH, and a third hybrid automatic repeat request (HARQ) process identifier (HPID) carried on the third PDCCH is the same with a first HPID, wherein the processor is further configured to determine, based on a third NDI carried on the third PDCCH and a first NDI, whether data carried on a third PDSCH scheduled by the third PDCCH is the multicast data retransmitted or new unicast data initially transmitted (Lei: Fig. 2; [0031], a PTM is first transmitted with GC- PDCCH; then a PTP based retransmission, in which the cyclic redundancy check (CRC) of the DCI is scrambled by a UE-specific RNTI (e.g., C-RNTI), can be used for scheduling the retransmission of the TB, with the same HARQ process ID and an untoggled NDI).
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 Wang wherein the terminal device further comprises :a transceiver, configured to receive a third PDCCH, wherein the third PDCCH is a user equipment (UE)-specific PDCCH, and a third hybrid automatic repeat request (HARQ) process identifier (HPID) carried on the third PDCCH is the same with a first HPID, wherein the processor is further configured to determine, based on a third NDI carried on the third PDCCH and a first NDI, whether data carried on a third PDSCH scheduled by the third PDCCH is the multicast data retransmitted or new unicast data initially transmitted as disclosed by Lei to provide a system for error case handling during multicast HARQ retransmission (Lei: Abstract).
Regarding claim 15, Wang teaches a non-transitory computer-readable storage medium storing a program that causes a computer to:
determine that a first physical downlink control channel (PDCCH) is a group-common physical downlink control channel (GC-PDCCH) (Wang: Fig. 1; [0037], UE receiving PDCCH for group of UE, i.e. GC-PDCCH for multicast transmission on PDSCH using scrambling by G-RNTI); and
determine that data carried on a first physical downlink shared channel (PDSCH) scheduled by the first PDCCH is new multicast data initially transmitted (Wang: Fig. 1; [0051], [0053], [0066], [0100], determining whether a transmission is an initial/new transmission based on scrambling by G-RNTI).
Wang does not explicitly disclose wherein the program further causes the computer to: receive a third PDCCH, wherein the third PDCCH is a user equipment (UE)-specific PDCCH, and a third hybrid automatic repeat request (HARQ) process identifier (HPID) carried on the third PDCCH is the same with a first HPID, and determine, based on a third NDI carried on the third PDCCH and a first NDI, whether data carried on a third PDSCH scheduled by the third PDCCH is the multicast data retransmitted or new unicast data initially transmitted.
Lei teaches wherein the program further causes the computer to: receive a third PDCCH, wherein the third PDCCH is a user equipment (UE)-specific PDCCH, and a third hybrid automatic repeat request (HARQ) process identifier (HPID) carried on the third PDCCH is the same with a first HPID, and determine, based on a third NDI carried on the third PDCCH and a first NDI, whether data carried on a third PDSCH scheduled by the third PDCCH is the multicast data retransmitted or new unicast data initially transmitted (Lei: Fig. 2; [0031], a PTM is first transmitted with GC- PDCCH; then a PTP based retransmission, in which the cyclic redundancy check (CRC) of the DCI is scrambled by a UE-specific RNTI (e.g., C-RNTI), can be used for scheduling the retransmission of the TB, with the same HARQ process ID and an untoggled NDI).
