Claims 1, 3-4, 7-8, 13, 16 are rejected under 35 U.S.C. 103 as being unpatentable over Xu et al. (US# 2020/0235876 hereinafter referred to as Xu) in view of Hosseini et al. (US# 2021/0112574 hereinafter referred to as Hosseini).
RE Claim 1¸ Xu discloses a user device, UE, for a wireless communication network, wherein the UE is to act as a relaying entity so as to provide functionality to support connectivity between a transmitting entity and a receiving entity of the wireless communication network (See Xu [0041], [0100], [0108] – UE acting as a relay node, between source and destination node), and
wherein, responsive to receiving a transmission from the transmitting entity:
if the transmission is directed to the relaying entity, sending a first feedback to the transmitting entity, wherein the first feedback indicates successful or non-successful receipt of the transmission at the relaying entity (See Xu [0041], [0100], [0108] – UE determines if node itself is destination of packet; if it is determined that the UE is the destination of the packet, the destination node sends HARQ-ACK back to source), and
if the transmission is directed to the receiving entity:
relaying the transmission towards the receiving entity, transmitting a second feedback instead of the first feedback to the transmitting entity (See Xu [0041], [0100], [0108] – UE determines if node itself is destination of packet; if it is determined that the UE is not the destination of the packet, the UE forwards the packet to the destination node; the destination node sends HARQ-ACK back to source either directly or through intermediate nodes (i.e. relay nodes); the UE, acting as a relay node, forwards received HARQ-ACK messages back to the source node),
wherein the second feedback indicates a successful and/or non-successful receipt of the transmission at the receiving entity (See Xu [0041], [0100], [0108] – the UE, acting as a relay node, forwards received HARQ-ACK messages back to the source node),
wherein the UE is to transmit the feedback received from the receiving entity (See Xu [0041], [0100], [0108] – the UE, acting as a relay node, forwards received HARQ-ACK messages back to the source node), wherein the UE uses SL in case the transmitting entity is a UE or a relaying entity (See Xu FIGs 1, 4; [0103]-[0104] – if the destination of the transmission (i.e. original transmitting entity that is now receiving the feedback) is another UE, the transmission takes place over SL), and wherein the UE uses UL in the case the transmitting entity is a network entity (See Xu FIGs 1, 4; [0103]-[0104] – if the destination of the transmission (i.e. original transmitting entity that is now receiving the feedback) is a base station, the transmission takes place over UL).
Xu does not specifically disclose the UE transmitting the feedback in the physical, PHY, layer; or
wherein the UE uses PSFCH when transmitting feedback on the sidelink, and wherein the UE uses PUCCH or PUSCH when transmitting feedback on the uplink (emphasis added).
However, Hosseini teaches of wherein the UE is to transmit the feedback received from the receiving entity in the physical, PHY, layer (See Hosseini FIG 2; [0091] – UE sending feedback on PSFCH or PUCCH),
wherein the UE uses PSFCH when transmitting feedback on the sidelink (See Hosseini FIG 2; [0091] – if UE sends feedback to another UE on the sidelink, transmission is on PSFCH), and wherein the UE uses PUCCH or PUSCH when transmitting feedback on the uplink (See Hosseini FIG 2; [0091] – if UE sends feedback to base station on the uplink, transmission is on PUCCH).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to implement the wireless communication system, wherein the UE uses SL in case the transmitting entity is a UE or a relaying entity, and wherein the UE uses UL in the case the transmitting entity is a network entity, as disclosed in Xu, wherein the UE transmitting the feedback in the physical, PHY, layer; and
wherein the UE uses PSFCH when transmitting feedback on the sidelink, and wherein the UE uses PUCCH or PUSCH when transmitting feedback on the uplink, as taught in Hosseini.

RE Claim 13¸ Xu discloses a user device, UE, for a wireless communication network,
Wherein the UE is to act as a relaying entity so as to provide functionality to support connectivity between a transmitting entity and one or more receiving entities of the wireless communication network (See Xu [0041], [0100], [0108] – UE acting as a relay node, between source and destination node),
wherein responsive to receiving the transmission from the transmitting entity, the UE is to transmit a first feedback to the transmitting entity using a first feedback link between the transmitting entity and the UE, the first feedback indicating a successful and/or non-successful receipt of the transmission at the UE (See Xu [0041], [0100], [0108] – UE determines if node itself is destination of packet; if it is determined that the UE is the destination of the packet, the destination node sends HARQ-ACK back to source),
wherein, responsive to receiving a transmission from the transmitting entity and to relaying the transmission towards the receiving entity, the UE is to transmit a second feedback to the transmitting entity, the second feedback indicating a successful and/or non-successful receipt of the transmission at the receiving entity (See Xu [0041], [0100], [0108] – UE determines if node itself is destination of packet; if it is determined that the UE is not the destination of the packet, the UE forwards the packet to the destination node; the destination node sends HARQ-ACK back to source either directly or through intermediate nodes (i.e. relay nodes); the UE, acting as a relay node, forwards received HARQ-ACK messages back to the source node), and
the UE is to transmit the second feedback associated with the receiving entity using a second feedback link between the transmitting entity and the UE (See Xu [0041], [0100], [0108] – the UE, acting as a relay node, forwards received HARQ-ACK messages back to the source node);
wherein the UE is to transmit the second feedback received from the receiving entity (See Xu [0041], [0100], [0108] – the UE, acting as a relay node, forwards received HARQ-ACK messages back to the source node), wherein the UE uses SL in case the transmitting entity is a UE or a relaying entity (See Xu FIGs 1, 4; [0103]-[0104] – if the destination of the transmission (i.e. original transmitting entity that is now receiving the feedback) is another UE, the transmission takes place over SL), and wherein the UE uses UL in the case the transmitting entity is a network entity (See Xu FIGs 1, 4; [0103]-[0104] – if the destination of the transmission (i.e. original transmitting entity that is now receiving the feedback) is a base station, the transmission takes place over UL).
Xu does not specifically disclose the UE transmitting the feedback in the physical, PHY, layer; or
wherein the UE uses PSFCH when transmitting feedback on the sidelink, the PSFCH resources scheduled by the transmitting entity for the first feedback, and wherein the UE uses PUCCH or PUSCH when transmitting feedback on the uplink, the PUCCH or PUSCH resources scheduled by the transmitting entity for the first feedback (emphasis added).
However, Hosseini teaches of wherein the UE is to transmit the feedback received from the receiving entity in the physical, PHY, layer (See Hosseini FIG 2; [0091] – UE sending feedback on PSFCH or PUCCH), the PSFCH resources scheduled by the transmitting entity for the first feedback (See Hosseini [0111], [0125] – UE may schedule SL resources),

It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to implement the wireless communication system, wherein the UE uses SL in case the transmitting entity is a UE or a relaying entity, and wherein the UE uses UL in the case the transmitting entity is a network entity, as disclosed in Xu, wherein the UE transmitting the feedback in the physical, PHY, layer; and

One is motivated as such in order to improve transmission error detection and satisfy timing capabilities (See Hosseini Background; Summary).
RE Claim 16¸ Xu, modified by Hosseini, discloses a user device, UE, as set forth in claim 15 above, wherein the UE is to receive from the network entity the resources to be used for reporting the first feedback and the second feedback (See Hosseini [0052] – BS may schedule resources used for feedback).
Claims 42, 53 are rejected under 35 U.S.C. 103 as being unpatentable over Xu et al. (US# 2020/0235876 hereinafter referred to as Xu) in view of Back et al. (US# 2023/0199875 hereinafter referred to as Back).
RE Claim 42¸ Xu discloses a wireless communication network (See Xu FIGs 1, 4; Background; Summary – wireless communication network), comprising

wherein, responsive to sending a transmission to the relaying entity for relaying to the receiving entity, the transmitting entity is to receive from the relaying entity a feedback, the feedback indicating a successful and/or non-successful receipt of the transmission at the receiving entity (See Xu [0041], [0100], [0108] – relay UE determines if node itself is destination of packet; if it is determined that the relay UE is not the destination of the packet, the relay UE forwards the packet to the destination node (receiving entity); the destination node (receiving entity) sends HARQ-ACK back to source either directly or through intermediate nodes (i.e. relay nodes); the UE, acting as a relay node, forwards the received HARQ-ACK messages back to the source node),

Xu does not specifically disclose
wherein the relaying entity and the transmitting entity operate in Mode 1 so that the base station indicates the resources to be used by the transmitting entity and the relaying entity,
wherein the relaying entity is configured or preconfigured with resources via configured grants for the transmission of the data to the receiving entity, and
wherein if the base station determines that the resources in the configured grants are not sufficient for the transmission of the data from the relaying entity to the receiving entity, the base station provides to the relaying entity a control message indicating additional resources for the transmission to the relaying entity.
However, Back teaches of
wherein the relaying entity and the transmitting entity operate in Mode 1 (See Back [0107] – mode 1) so that the base station indicates the resources to be used by the transmitting entity and the relaying entity (See Back [0174], [0176], [0181] – base station allocates resources to be used by transmitting entity and relaying entity),
wherein the relaying entity is configured or preconfigured with resources via configured grants for the transmission of the data to the receiving entity (See Back [0174], [0181] – relaying UE configured/preconfigured with resources via CGs for transmission to remote UE), and
wherein if the base station determines that the resources in the configured grants are not sufficient for the transmission of the data from the relaying entity to the receiving entity, the base station provides to the relaying entity a control message indicating additional resources for the transmission to the relaying entity (See Back [0176] - The BS may determine whether to extend/reduce the default relay resource pool through a multiplexing value, for example, resources allocated to all remote UE(s) reported by the relay UE or the amount/period of necessary resources received from the remote UE. When it is determined that the default relay resource pool needs to be expanded/reduced, the BS may allocate additional resources to the relay UE by reflecting the result of determination or may transmit a control signal such as a signal for excluding a specific part from previously allocated resources).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to implement the wireless communication system, as disclosed in Xu, wherein the relaying entity and the transmitting entity operate in Mode 1 so that the base station indicates the resources to be used by the transmitting entity and the relaying entity,
wherein the relaying entity is configured or preconfigured with resources via configured grants for the transmission of the data to the receiving entity, and
wherein if the base station determines that the resources in the configured grants are not sufficient for the transmission of the data from the relaying entity to the receiving entity, the base station provides to the relaying entity a control message indicating additional resources for the transmission to the relaying entity, as taught in Back. One is motivated as such in order to help prevent QoS degradation while determining to utilize relay service (See Back Background; Summary).
RE Claim 53¸ Xu, modified by Back, discloses a wireless communication network, as set forth in claim 42 above, wherein the transmitting entity is the base station of the wireless communication network (See Xu [0041], [0100], [0108] – eNB).

Xu, modified by Hosseini, does not specifically disclose if the UE receives no feedback from the receiving entity, the UE transmits the second feedback to indicate a non-successful receipt of the transmission at the receiving entity.
However, Fang teaches of if the UE receives no feedback from the receiving entity, the UE transmits the second feedback to indicate a non-successful receipt of the transmission at the receiving entity (See Fang [0130] – relay node sends NACK if it doesn’t receive response from next hop (loses backhaul link)).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to implement the wireless communication system, as disclosed in Xu, modified by Hosseini, wherein if the UE receives no feedback from the receiving entity, the UE transmits the second feedback to indicate a non-successful receipt of the transmission at the receiving entity, as taught in Fang.

Xu, modified by Hosseini, does not specifically disclose wherein, responsive to the one or more predefined events, the UE is to transmit to the transmitting entity the second feedback indicating a non-successful receipt of the transmission at the receiving entity, within a configured or pre-configured time window following the receipt of the feedback.
However, Fang teaches of wherein, responsive to the one or more predefined events, the UE is to transmit to the transmitting entity the second feedback indicating a non-successful receipt of the transmission at the receiving entity, within a configured or pre-configured time window following the receipt of the feedback (See Fang [0130] – if no ACK/NACK is received, relay node retransmitting packet up to a couple times and then sending NACK back to the transmitting entity at configured time window (e.g. at earliest possible opportunity)).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to implement the wireless communication system, as disclosed in Xu, modified by Hosseini, wherein, responsive to the one or more predefined events, the UE is to transmit to the transmitting entity the second feedback indicating a non-successful receipt of the transmission at the receiving entity, within a configured or pre-configured time window following the receipt of the feedback, as taught in Fang.

RE Claim 14¸ Xu, modified by Hosseini, discloses a user device, UE, as set forth in claim 13 above, wherein, if the transmitting entity is another UE or a relaying entity (See Xu [0041], [0100], [0108] – transmitting/receiving entity can be UE, relay UE, or network entity).
Xu, modified by Hosseini, does not specifically disclose wherein, if the transmitting entity is another UE or a relaying entity, the resources for transmitting the feedback received from the receiving entity is mapped:
implicitly by a relationship between the mapping on the PSFCH resources for a feedback transmission from the receiving entity to the UE and a feedback transmission from the UE to the transmitting entity, or
explicitly by the transmitting entity indicating to the UE which resources on the PSFCH are to be used for the reporting of feedback associated with the receiving entity.
However, ZTE teaches of wherein, if the transmitting entity is another UE or a relaying entity, the resources for transmitting the feedback received from the receiving entity is mapped:
implicitly by a relationship between the mapping on the PSFCH resources for a feedback transmission from the receiving entity to the UE and a feedback transmission from the UE to the transmitting entity, or
explicitly by the transmitting entity indicating to the UE which resources on the PSFCH are to be used for the reporting of feedback associated with the receiving entity (See ZTE Section 2.4 – remote UE selecting resources; resources used by the remote UE are received by the Relay UE).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to implement the wireless communication system, as disclosed in Xu, modified by Hosseini, wherein, if the transmitting entity is another UE or a relaying entity, the resources for transmitting the feedback received from the receiving entity is mapped:
implicitly by a relationship between the mapping on the PSFCH resources for a feedback transmission from the receiving entity to the UE and a feedback transmission from the UE to the transmitting entity, or
explicitly by the transmitting entity indicating to the UE which resources on the PSFCH are to be used for the reporting of feedback associated with the receiving entity, as taught in ZTE. One is motivated as such in order to reduce the incidence of resource selection and benefit the Relay UE detection (See ZTE Section 2.4).
