The base station (2) then calculates a reception error rate of the paging information, based on the statistic. When receiving the paging information, the mobile station (8) transmits a response signal to the base station (8).

Abstract: When an RG received from a base station is UP, a mobile station compares E-TFC currently used by a HARQ process for transmitting a signal to the base station from the mobile station with E-TFC previously used for transmission by the same HARQ process. When they are identical, the accumulation information is incremented by one. When selecting E-TFC used for transmission, the HARQ process of the mobile station tales the accumulation information into consideration. Thus, when the accumulation is incremented, the HARQ process selects E-TFC of a level incremented by one and accordingly, the transfer rate of the mobile station is increased and the user throughput is improved.
