<p>An apparatus and method for uplink time synchronization in a communication system includes a first step 602 of receiving uplink data from a user equipment. A next step 604 includes storing a time error of the uplink data along with a time stamp. A next step 620 includes integrating the time error to provide an accumulated time error. A next step 606, 626 includes dumping the accumulated time error upon the time stamps of the accumulated data meeting a timing condition. A next step 610 includes comparing the accumulated time error against a threshold. A next step 616 includes scheduling a time advance with the user equipment if the accumulated time error exceeds the threshold.</p> |
