US 11,121,794 B2 · Configurable synchronization in next generation wireless networks

Abstract

Aspects of the present disclosure provide for the transmission of various synchronization signals with variable periodicity. For synchronization signals with long periodicity, in some aspects of the disclosure, the synchronization signals may be transmitted as single-frequency-network (SFN) synchronization signals and/or the synchronization signals may be repeated a number (N) of times within a synchronization burst to reduce user equipment (UE) search latency and improve UE measurement accuracy. In some examples, the synchronization signals may be repeated within a synchronization burst using a repetition pattern that may be configurable based on the periodicity of transmission or fixed for one or more periodicities of transmission.
