<p>There are included a receiver that receives an upstream signal from a first mobile station; a sync signal detection timing measuring means that measures a detection timing of an upstream sync signal included in the received upstream signal; and a reception tolerance control means that decides a reception tolerance of the sync signal of the sync signal detecting means, based on the measurement results of the latest detection timing and of a plurality of past detection timings. Thus, even when the distance between the base station and the mobile station increases due to a movement of the mobile station and hence the propagation delay of the radio signals increases, the communication can be performed with less erroneous detection of the sync signal and without any control of transmission timing at the mobile station.</p> |
