摘要： A radio station, a radio terminal, and a method for transmission timing control in a radio communications system are provided that facilitate uplink-signal synchronization management in a plurality of cell groups. The radio station (10) calculates uplink-signal transmission timing adjustment values TA1 and TA2 for respective cell groups (1, 2), each of which includes at least one cell including an available uplink radio resource, and notifies the calculated uplink-signal transmission timing adjustment values TA1 and TA2 to the radio terminal (20) at a time.

摘要： Even when a radio terminal cannot receive content data from a base station to which the radio terminal serves, the radio terminal receives the content data from other base station. A wireless communication system (1) includes a plurality of radio base stations (21 to 23) and a radio terminal (40). The radio terminal (40) serves to a specific radio base station (serving radio base station) among the radio base stations (21 to 23). Moreover, the radio terminal (40) receives content data which is broadcasted or multicasted from a non-serving radio base station among the radio base stations (21 to 23) according to a gap pattern.

摘要： A wireless communication system is provided for reducing the probability that latency before data transmission increases when a mobile station that is actually in sync is judged to be out of sync. A base station causes the timing calculation part to calculate the timing advance (TA) of a transmit timing from the mth mobile station; causes the timer adaptive control part to obtain the traveling speed or the time variation in TA of the mth mobile station and, adaptively determines and outputs as the timer update information the length of the mth first timer within an M number in total of synchronization timers and the length of the second timer of the mth mobile station and update the length of the mth first timer; and transmits from the downlink transmission part a downlink signal which contains timer update information.
