Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling distributed frequency synchronization based on an average clock rate. In one example, a UE is equipped to receive a synchronization signal from each of one or more UEs, perform an averaging process to generate an average clock rate based at least on the received synchronization signals, and adjust an internal clock rate based on the average clock rate. In another example, a UE is equipped to adjust an internal clock rate of a UE based on timing information provided by a GPS, select a sequence to communicate a synchronization signal transmission from a subset of sequences reserved for GPS connected UEs, and transmit the synchronization signal based on the adjusted internal clock rate.
