Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a system and method for providing timing synchronization in a wireless communication system.

SOLUTION: The uplink timing synchronization may be provided via a specific message sent from user equipment to a network access device or may be calculated based upon data received at the network access device from the user equipment. The method comprises: receiving an uplink timing reference signal transmission instruction message; determining a time interval to send a timing reference signal transmission in accordance with the timing reference signal transmission instruction message; evaluating if uplink data is to be sent in the time interval; and if there is data to be sent sending the data in the time interval and not sending the timing reference signal transmission in the time interval else sending the timing reference signal transmission in the time interval.
