METHODS AND APPARATUS FOR UPLINK FRAME SYNCHRONIZATION IN A SUBSCRIBER STATION

摘要

A method for uplink frame synchronization in a subscriber station may include recording a first time stamp corresponding to a first downlink frame and recording a second time stamp corresponding to a second downlink frame. The first time stamp and the second time stamp may be used to determine a propagation delay change. Uplink transmission timing may be adjusted based on the propagation delay change that is determined.
