  • Publication number: 20200305150
    Abstract: It is possible to solve the problem that a downstream control information amount is significantly increased if allocation information is periodically reported because no allocation method of a default E-DCH resource configuration is defined for a preamble signature. A base station and a mobile station decide a default resource configuration by using a total number of resource configurations or a value obtained from the total number.

  • Patent number: 10638454
    Abstract: Even when a radio terminal cannot receive contents data from a serving base station, the radio terminal can receive the contents data from other base station. A wireless communication system includes a radio terminal, a serving radio base station to which the radio terminal serves, and a non-serving radio base station to which the radio terminal does not serve. The serving radio base station receives, from the non-serving radio base station, contents-related information concerning contents data to be broadcasted or multicasted by said non-serving radio base station, and transmits the received contents-related information to the radio terminal.

  • Patent number: RE47721
    Abstract: 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.
