Patent ID: 7023835

Claim:
A communication system for supporting base station (BS)/mobile terminal (MT) wireless bi-directional communications via utilization of a radio frame format defined by radio frames that include a numeric identifying designation comprising: a BS having: a transmitter configured to transmit selectively formatted communication data to MTs within system radio frames, and a receiver configured to receive communication data from MTs within system radio frames; said BS receiver having an associated processor configured to measure timing deviation (TD) of received radio frames in which communication data is received from a selected MT; a timing advance (TA) signal generator associated with said BS configured to provide TA command signals for transmission by said BS to selected MTs; said TA command signal generator configured to generate TA command signals which include: TA data which is calculated based upon measured TD in a received radio frame for a selected MT, and a Connect Frame Number (CFN) specifying a particular radio frame for effectuating a timing adjustment by the selected MT; and said BS processor configured to measure the TD for communication data received from a selected MT to which a TA command signal had been transmitted in the frame specified in the CFN of the transmitted TA command signal.
