Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling distributed frequency synchronization based on a fastest node clock rate. In one example, a first UE is equipped to determine that a fastest clock rate is faster than an internal clock rate of the first UE by more than a first positive offset, and adjust the internal clock rate based on the determined fastest clock rate. In an aspect, the fastest clock rate is associated with a second UE of one or more other UEs from which synchronization signals may be received. In another example, a UE is equipped to obtain GPS based timing information, adjust an internal clock rate based on the GPS based timing information, and transmit a synchronization signal at an artificially earlier time in comparison to a scheduled time of transmission associated with the adjusted internal clock rate.
