[0008] discloses controller/processor coupled with memory) with one or more processors (see Fig. 2 (240 processor) para. [0008] discloses controller/processor coupled with memory).
Xu fails to disclose but Abedini teaches are further configured to cause the first network node to receive an inter-UE cross-link interference (CLI) report from the second network node, the inter-UE CLI report being associated with a second UE (see Fig. 7 (720, 740,745), para. [0032];[0099];[0103] discloses inter DU CLI; reception of UL communication from a UE (745), overlaps DL communication (740)).
Xu and Abedini are considered analogous to the claimed invention because both are in the field of wireless communication methods, apparatus and uplink transmission.
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify Xu to include the CLI for the second node as described by Abedini.
The motivation to combine both references would come from improving signaling during cross-link interference mitigation.
Regarding claim 16, Xu discloses a first network node (see Fig. 1 (110a)) with one or more processors (see Fig. 2 (240 processor) para. [0008] discloses controller/processor coupled with memory) with one or more processors (see Fig. 2 (240 processor) para. [0008] discloses controller/processor coupled with memory).
Xu fails to disclose but Abedini teaches are further configured to cause the first network node to receive, from a distributed unit (DU), an indication that the first UE has been configured with an inter-UE cross-link interference (CLI) configuration (see Fig. 7 (720, 740,745), para. [0032];[0099];[0103] discloses inter DU CLI; reception of UL communication from a UE (745), overlaps DL communication (740)).
Xu and Abedini are considered analogous to the claimed invention because both are in the field of wireless communication methods, apparatus and CLI.
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify Xu to include the distribute unit and CLI as described by Abedini.
The motivation to combine both references would come from improving signaling during cross-link interference mitigation.
