Abstract: A mobile relay generates a synchronization signal/physical broadcast channel block (SSB) for the mobile relay using at least one of a primary synchronization signal (PSS) for mobile relays that is different than a stationary base station PSS, a secondary synchronization signal (SSS) for mobile relays that is different than a stationary base station SSS, a physical broadcast channel (PBCH) that is different than a stationary base station PBCH, or a demodulation reference signal (DMRS) associated with the PBCH that is different than a stationary base station DMRS. After generating the SSB, the mobile relay broadcasts the SSB. A UE receiving the SSB determines that the SSB is from a mobile relay based, at least in part, on information comprised in the SSB.

Abstract: Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. In one aspect a wireless communication technique takes into account the load of a donor gNB before a relay decides to reselect from one donor gNB to another. In another aspect, a wireless communication technique ensures that relays are handed over to base stations that will be able to serve the relay as the mobile relay continues to follow its expected path (e.g. streets or tracks).
