Claim 1. BAE teaches: A method performed by a Distributed Unit (DU) of a wireless communication node in a wireless network, the method comprising: - See Fig. 2-3, ¶ [0069], (“the DU 232 transmits…”)
transmitting a first transferring message to a Central Unit (CU) of the wireless communication node, - See Fig. 2B, ¶ [0069], (“in step S222, the DU 232 transmits the RRC message of the remote UE 210 to the CU 234 using the F1 or W1 message (e.g., INITIAL UL RELAY RRC MESSAGE TRANSFER message or UL RELAY RRC MESSAGE TRANSFER message).”)
wherein the first transferring message comprises an identifier (ID) of a remote user equipment (UE) - See Fig. 2B, ¶ [0069], (“The F1 or W1 message (e.g., INITIAL UL RELAY RRC MESSAGE TRANSFER message, UL RELAY RRC MESSAGE TRANSFER message) transmitted in step S222 may include remote UE identifier (e.g., remote UE identification) information...”) and a DU level relay UE ID that identifies a relay UE in the DU, - See Fig. 2, ¶ [0076], (“The F1 or W1 message (e.g., INITIAL UL RELAY RRC MESSAGE TRANSFER message, UL RELAY RRC MESSAGE TRANSFER message) transmitted in step S222…a UE identifier (e.g., gNB-CU UE F1AP ID and gNB-CU UE F1AP ID) in the F1 or W1 message…and a UE identifier configured to distinguish the relay UE”)

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 BAE and WANG’534 with WANG to include the ID of the remote UE comprises a local UE ID allocated by the CU, as taught by WANG. One of ordinary skill in the art would have been motivated to make this modification to result in efficient resource management, as suggested by WANG, In order to solve this problem, the base station needs to configure related resources for the relay terminal, so that the relay terminal can perform data transfer of other users on the configured resources. - ¶ [0293]

Claim 72. Combination of BAE, WANG’534, and WANG teaches The method of claim 12, - refer to the indicated claim for reference(s).
Luo further teaches:
wherein: the first F1 Application Protocol (F1AP) signaling triggers configuring a Uu RLC channel - See Fig. 6, ¶ [0111], (“A CU generates a UE context modification request message…used to request a DU to modify a context of relay UE”); ¶ [0114], (“the CU may request to add a DRB and an SRB for the relay UE.”, Adding SRB/DRB corresponds to configuring Uu channels and the DU receives this message from the CU.); ¶ [0124], (“UE context modification request message may be encapsulated in an F1 message”) between the DU and the relay UE; - in ¶ [0156], (“a logical channel that is between the relay UE and the DU and that corresponds to the SRB”) the second F1AP signaling triggers configuring PC5 RLC channel between the relay UE and the remote UE; - in ¶ [0111 – 0112], (“A CU generates a UE context modification request message…the logical channel between the remote UE and the relay UE is…a logical channel of a PC5 interface”); ¶ [0114], (“the CU may request to add a DRB and an SRB for the relay UE. Then, the CU may determine…an identifier of the logical channel between the relay UE and the remote UE”) and the Uu RLC channel and the PC5 RLC channel are used to deliver traffic destined to the remote UE, - in ¶ [0152 – 0153], (“if the adaptation information carries the identifier of the remote UE 2 and the LCID 4, the relay UE sends the downlink RRC information to the remote UE 2 through the logical channel LCID 4…an RLC layer of a PC5 interface between the relay UE and the remote UE 2.”) and wherein the relay UE serves as a relay between the remote UE and the wireless communication node. - See Fig. 1, 4, ¶ [0153], (“a Uu interface between the relay UE and the DU…a PC5 interface between the relay UE and the remote UE 2”)
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 BAE, WANG’534, and WANG with Luo to specify channels between DU and relay UE and between relay UE and remote UE, as taught by Luo. One of ordinary skill in the art would have been motivated to make this modification to improve wireless communication, as suggested by Luo, In this case, when the base station is deployed by using the CU-DU architecture, how to implement a user equipment-to-network relay (UE-to-Network relay) communication process becomes a problem. - ¶ [0004]
Claim 74 is rejected under the same rationale as Claim 71 since they recite nearly identical limitations.
Claim 75 is rejected under 35 U.S.C. 103 as being unpatentable over BAE et al (US 20240389181, hereinafter, “BAE”) in view of WANG et al. (WO 2022082534 A1, hereinafter, “WANG’534”), and further in view of WANG et al. (US 20220353784, hereinafter, “WANG”) and Masini et al. (US 20160127963, hereinafter, “Masini”).
Claim 75. Combination of BAE, WANG’534, and WANG teaches The method of claim 12, - refer to the indicated claim for reference(s).
BAE teaches:
further comprising transmitting a sixth message to the DU, the sixth message comprising sidelink communication authorization information for at least one of: - See Fig. 2, ¶ [0085], (“in step S237, the CU 234 transmits an F1 or W1 message (e.g., UE CONTEXT MODIFICATION REQUEST message) to the DU 232”)
Combination of BAE, WANG’534, and WANG does not explicitly teach:
further comprising transmitting a sixth message to the DU, the sixth message comprising sidelink communication authorization information for at least one of: the relay UE, or the remote UE, wherein the sidelink communication authorization information comprises at least one of: a 5G Proximity Service (ProSe) Layer-2 UE-to-Network Relay authorization for the relay UE; or a Layer-3 UE-to-Network Relay authorization for the relay UE; a 5G ProSe Layer-2 Remote UE authorization; or a ProSe Direct Discovery authorization.
However, Masini teaches:
further comprising transmitting a sixth message to the DU, the sixth message comprising sidelink communication authorization information for at least one of: the relay UE, or the remote UE, - in ¶ [0060] the ProSe Authorized IE (Information Element)…can be added to the UE CONTEXT MODIFICATION REQUEST message so that the ProSe authorizations for the UE can be modified”) wherein the sidelink communication authorization information comprises at least one of: a 5G Proximity Service (ProSe) Layer-2 UE-to-Network Relay authorization for the relay UE; or a Layer-3 UE-to-Network Relay authorization for the relay UE; a 5G ProSe Layer-2 Remote UE authorization; or a ProSe Direct Discovery authorization. - See Fig. 4, ¶ [0060], (“the ProSe Authorized IE (Information Element)…can be added to the UE CONTEXT MODIFICATION REQUEST message so that the ProSe authorizations for the UE can be modified”…¶ [0061], (“When receiving a ProSe Authorized IE as defined above, the eNB may know not only if the UE is authorized for ProSe, but also which services it is authorized to support…ProSe direct discovery…an in-network UE may act as a ProSe UE-to-Network Relay providing connection between an out-of-network remote UE (over a PC5 interface) and a…base station eNB (over a Uu interface).”)
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 BAE, WANG’534, and WANG with Masini to include authorization information, as taught by Masini. One of ordinary skill in the art would have been motivated to make this modification to improve wireless communication, as suggested by Masini, receiving the authorization may know not only if a UE is authorized for ProSe, but also which services the UE is authorized to support. Accordingly, the base station may be able to estimate an amount and type of resources that the UE may use according to the type of service. - ¶ [0012]
