Abstract
An apparatus and method for uplink time synchronization in a communication system includes a first stepof receiving uplink data from a user equipment. A next stepincludes storing a time error of the uplink data along with a time stamp. A next stepincludes integrating the time error to provide an accumulated time error. A next stepincludes dumping the accumulated time error upon the time stamps of the accumulated data meeting a timing condition. A next stepincludes comparing the accumulated time error against a threshold. A next stepincludes scheduling a time advance with the user equipment if the accumulated time error exceeds the threshold.
