Multi-path operation in ue-to-nw sidelink relay

A processor of a user equipment (UE) configured to perform operations comprising:

• receiving a conditional path addition (CPA) command from a base station on a first path between the UE and the base station, wherein the CPA command indicates a CPA configuration containing CPA trigger conditions and a multi-path configuration;
• executing the CPA command in accordance with a determination that at least one of the CPA trigger conditions is fulfilled;
• and
• establishing a second path between the UE and the base station in accordance with the determination that the CPA is to be executed.

A processor of a base station (BS) configured to perform operations comprising:

• receiving from, a user equipment (UE), a measurement report on a first path between the UE and the base station, wherein the measurement report indicates channel quality information on one or more potential paths between the UE and the base station;
• determining a second path to be added from the one or more potential paths based on the measurement report;
• transmitting a path addition command to the UE, wherein the path addition command instructs the UE to add a second path;
• and
• assisting to establish the second path between the UE and the base station.
