Claims 1-2,4,6,9-10,12 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over YEO et al. (US 2020/0106566 A1; hereinafter “YEO”), in view of Ganesan et al. (US 2023/0231654 A1; hereinafter “Ganesan”), and further in view of HWANG et al. (US 2022/0216975 A1; hereinafter “HWANG”).
Regarding claim 1, YEO teaches a method performed by a first terminal (FIG. 19 a terminal 1900) in a wireless communication system ([0009] a method of a terminal in a communication system), the method comprising:
receiving, from a base station (FIG. 19 TRP 1 1910), hybrid automatic repeat request (HARQ) configuration information ([0064] DCI including HARQ-related parameters (e.g., HARQ process number, new data indicator (NDI), redundancy version) is transferred from a base station to a terminal, [0137] the base station transfers configuration information required for transmission/reception to the terminal),
wherein the HARQ configuration information includes information on a mixed mode for applying both a HARQ feedback-based retransmission ([0135] HARQ-ACK feedback) and a blind retransmission ([0135] absence of HARQ-ACK feedback implies retransmission without feedback, i.e., blind retransmission) to a medium access control (MAC) protocol data unit (PDU) corresponding to a sidelink logical channel, a first configuration value for a number of transmissions of the HARQ feedback-based retransmission, and a second configuration value for a maximum number of transmissions ([0135] whether HARQ-ACK feedback transmission is performed is configured, thereby enabling HARQ feedback-based retransmission or blind retransmission, [0137] the base station configures the number of HARQ processes to be used for transmission/reception, [0138] wherein operation is determined based on configured HARQ process number);
based on the HARQ configuration information, determining that a MAC PDU to be transmitted is configured to the mixed mode ([0135] the terminal checks whether HARQ-ACK feedback is configured and determines operation based on the configuration, [0138] determines operation based on a configured HARQ process number);
identifying whether to retransmit the MAC PDU ([0229] the transmission device determines whether all of the CBs in the TB have been successfully decoded by the at least one reception device based on the feedback information received from the at least one reception device);
in case that the first terminal determines to retransmit the MAC PDU ([0230] if all of the CBs in the TB have not been successfully decoded, the transmission device determines, based on the feedback information received from the reception device, the number of PCBs to be transmitted, and transmits the determined number), determining a first retransmission mode for the MAC PDU ([0182] TB-related configuration information indicates a MCS, a NDI, and a redundancy version (RV), a HARQ process number, a PUCCH resource indicator, a PDSCH-to-HARQ feedback timing indicator, [0252] The SCI includes a NDI, a RV, HARQ process number/feedback indication)
retransmitting, to a second terminal, the MAC PDU by applying the first retransmission mode ([0225] the transmission device transmits data CBs and/or PCBs. The transmission of data step 2205 may be retransmission of data, [0226] the reception devices transmit feedback information, such as HARQ-ACK feedback, to the transmission device).
However, YEO does not teach identifying whether to retransmit the MAC PDU; in case that the first terminal determines to retransmit the MAC PDU, determining a second retransmission mode for the MAC PDU; and in response to the determination to retransmit the MAC PDU retransmitting the MAC PDU, to the second terminal, by applying the second retransmission mode, wherein incase that the first retransmission mode is the HARQ feedback-based retransmission, the second retransmission mode is the blind retransmission, and the first terminal performs the HARQ feedback-based retransmission for the first configuration value, the first terminal performs the blind retransmission until a cumulative number of transmissions reaches the second configuration value.
In an analogous art, Ganesan teaches identifying whether to retransmit the MAC PDU ([0205] determine whether to perform retransmission of the TB);
in case that the first terminal determines to retransmit the MAC PDU ([0205] determine whether to perform retransmissions, [0208] retransmission is performed based on the determination), determining a second retransmission mode for the MAC PDU ([0205] selecting a retransmission mode, [0180] selecting the retransmission mode based on a pattern of blind retransmissions and HARQ feedback-based transmissions); and
in response to the determination to retransmit the MAC PDU retransmitting the MAC PDU, to the second terminal, by applying the second retransmission mode ([0205] selecting a retransmission mode and selecting sidelink resources for retransmission of the TB based on the selected mode; [0208]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify a HARQ feedback as taught by Ganesan within the parameter of YEO. One would have been motivated to do so in order to avoid un-necessary blind re-transmission with conserving the system resource efficiently (Ganesan [0034]).
However, the combination of YEO and Ganesan does not teach wherein incase that the first retransmission mode is the HARQ feedback-based retransmission, the second retransmission mode is the blind retransmission, and the first terminal performs the HARQ feedback-based retransmission for the first configuration value, the first terminal performs the blind retransmission until a cumulative number of transmissions reaches the second configuration value.
In an analogous art, HWANG teaches wherein incase that the first retransmission mode is the HARQ feedback-based retransmission ([0123]-[0124] HARQ feedback-based retransmission based on ACK/NACK), the second retransmission mode is the blind retransmission ([0174]-[0175] blind retransmission of a TB or MAC PDU), and
the first terminal performs the HARQ feedback-based retransmission for the first configuration value, the first terminal performs the blind retransmission until a cumulative number of transmissions reaches the second configuration value ([0135]-[0137] bounded HARQ retransmission, [0174]-[0175] blind retransmission when HARQ feedback is not used, [0179]-[0180] disclose transmissions up to a pre-configured maximum number (TX_NUM)).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the retransmission as taught by HWANG within the parameter of YEO and Ganesan. One would have been motivated to do so in order to reduce data traffic with performing SL communication to enhance user experience (HWANG [0018]).
Regarding claim 2, the combination of YEO, Ganesan and HWANG, specifically Ganesan teaches wherein the HARQ configuration information further includes information on a maximum number of transmissions for the blind retransmission, information on a packet delay budget (PDB) requirement, and information on a latency requirement ([0153]-[0154] discloses that a total number of transmissions depends on latency boundary including packet delay budget (PDB), corresponding to a latency requirement, and that a number of blind retransmissions based on a given and remaining PDB, thereby defining a transmission count constraint corresponding to a maximum number of transmissions).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify a HARQ feedback as taught by Ganesan within the parameter of YEO. One would have been motivated to do so in order to avoid un-necessary blind re-transmission with conserving the system resource efficiently (Ganesan [0034]).
Regarding claim 4, the combination of YEO, Ganesan and HWANG, specifically Ganesan teaches wherein in case that the first retransmission mode is the HARQ feedback-based retransmission and the sidelink logical channel fails to satisfy the PDB requirement, the second retransmission mode is the blind retransmission ([0044] The Tx UE may be configured with one or more condition for switching from blind retransmission to HARQ feedback-based retransmission or vice versa—based on remaining PDB, [0164] for switching between blind retransmission to HARQ feedback-based retransmission is configurable at the Tx UE side based on the UE processing capability or priority of the packet transmission, or remaining PDB).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify a HARQ feedback as taught by Ganesan within the parameter of YEO. One would have been motivated to do so in order to avoid un-necessary blind re-transmission with conserving the system resource efficiently (Ganesan [0034]).
Regarding claim 6, the combination of YEO, Ganesan and HWANG, specifically HWANG teaches wherein in case that the first retransmission mode is the HARQ feedback-based retransmission and a resource for transmitting the MAC PDU is selected from a resource pool that does not include a physical sidelink feedback channel (PSFCH) resource, the second retransmission mode is the blind retransmission ([0175] performing, by the UE, blind retransmission may include: transmitting, by the UE, a TB or a MAC protocol data unit (PDU) by setting a predefined HARQ feedback request field value in a SCI to a “NOT REQUESTED” state, if at least one of the following conditions is satisfied, although the TB or the MAC PDU transmitted by the UE includes data related to HARQ ENABLED LCH(s)).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify a PSFCH resource as taught by HWANG within the parameter of YEO and Ganesan. One would have been motivated to do so in order to reduce data traffic with performing SL communication to enhance user experience (HWANG [0018]).

wherein in case that the first retransmission mode is the HARQ feedback-based retransmission and the sidelink logical channel is allowed to be multiplexed with a sidelink logical channel configured to the blind retransmission ([0440] The PSSCH is a physical channel used for shared data transmission for side link operation, one or more second DCI fields (e.g., auxiliary DCI fields for decoding the scheduled PSSCH transmission) in the second-stage DCI, [0556] the scheduled transmission is based on the information associated with the second-stage DCI, it comprises hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback associated with the data, The second-stage DCI is multiplexed with data scheduled by the first-stage DCI), the second retransmission mode is the blind retransmission ([0433] A base station may dynamically enable/disable acknowledgment feedback (e.g., HARQ-ACK feedback) from a wireless device. The base station attempts blind repetition in which acknowledgment feedback for each repetition may not be needed).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the DCI as taught by Yi within the parameter of YEO, Ganesan and HWANG. One would have been motivated to do so in order to reduce higher latency of data transmission with efficiently performing wireless network to enhance user experience (Yi [0349]).
