Relay communication management in response to cellular connection radio link failure (RLF)

Abstract

An initial relay user equipment (UE) device transmits a llu radio link failure (RLE) notification to a remote UE device when the Uu communication link from the initial relay UE device to the serving base station fails. The remote UE device refrains from sending signals to the serving base station through the initial relay UE device at least until receiving a Uu link reestablished notification indicating that the Uu communication link has been reestablished. In some situations, the remote UE device identifies a preferred candidate relay UE device after receiving the Uu RLF notification and selects the preferred candidate relay UE device for relay communication in response to receiving a Uu link reestablished notification indicating the Uu communication link could not be reestablished.
