SYNCHRONIZATION SIGNAL SELECTION ACROSS MULTIPLE TRANSCEIVER NODES

Abstract:

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to select a synchronization signal from multiple synchronization signals received at transceiver nodes of the UE based on configured selection rules. The UE may receive control signaling from another UE, a base station, or some other device indicating a rule for selecting between multiple synchronization signals received across transceiver nodes of the UE. The selection rule may indicate signal quality comparison metrics for selecting the synchronization signal, such as reference signal received power (RSRP) metrics, timing metrics, priority metrics, or a combination thereof. The UE may select a synchronization signal for deriving a timing at the UE based on the selection rule. The UE may forward the selected synchronization signal to one or more other UEs by transmitting the selected synchronization signal via each transceiver node at the UE.
