ACTIVATION/DEACTIVATION OF DIRECT LINK IN DUAL/MULTI-CONNECTIVITY WITH UE RELAYS

Abstract:

A configuration utilising L1/L2 signaling to activate or deactivate a direct link in dual or multi-connectivity with relaying devices. The apparatus communicates with a base station using a direct link and using a relay link. The relay link comprises a side link between a first UE and a second UE and a second direct link between the second UE and the base station. The apparatus transmits or receives a request to deactivate the direct link based on a determination by at least one of the base station, the first UE, or the second UE that the direct link between the first UE and the base station is to be deactivated. The request to deactivate the direct link comprises L1 or L2 signaling. The apparatus receives a deactivation command to deactivate the direct link.
