Abstract
End-to-end latency measurements for synchronization are described. A first wireless device may determine an uplink latency associated with sending communications to a second wireless device. The first wireless device may determine a downlink latency associated with receiving communications from the second wireless device. Based on the uplink latency being different from the downlink latency, the first wireless device, the second wireless, and/or a base station may perform an alignment (e.g., time-based alignment, channel-based alignment) to modify and/or adjust one or more parameters to make the uplink latency equivalent to the downlink latency.
