ABSTRACT:
A mobile apparatus and method of timing synchronization. The mobile apparatus comprises a timing synchronization controller, a frame detector, a decoder, and a clock generator. The timing synchronization controller determines a number of times of the mobile station clock switching from a first clock speed to a second clock speed, and compares the number of times of the mobile station clock switching the clock speed with a predetermined number of clock speed switch. The frame detector, coupled to the timing synchronization controller, receives a control channel block when the number of times of clock speed switch reaches the predetermined number of clock speed switch. The decoder, coupled to the frame detector, decodes the control channel block to compute a timing error between the base station clock and the mobile station clock. The clock generator, coupled to the decoder, receives the timing error to compensate for the mobile station clock.
