Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a remote user equipment (UE) may communicate with a base station via a relay UE. For example, the relay UE may operate as a layer 2 (L2) UE-to-network relay supporting a PC5-to-Uu bearer mapping, such that the relay UE forwards messages between the PC5 bearer for the remote UE and the Uu bearer for the base station. If the remote UE determines a trigger event, the remote UE may transmit a measurement report to the base station (e.g., via the relay UE) indicating candidate relays. Based on the measurement report, the base station may determine to handover the UE from using a first relay UE to using a second relay UE. The base station may transmit a handover command to the UE, triggering the remote UE to communicate with the base station via the second relay UE.

In some cases, the base station may send to the UE, an explicit indication of the contingency bandwidth part. In some cases, the UE may identify the contingency bandwidth part based on a reference signal. Upon determining the contingency bandwidth part, the UE may perform the random access procedure using the contingency bandwidth part.
