Wireless communications system, base station, and mobile station

摘要

A wireless communications system including a mobile station (MS) and base stations (BS1 and BS2), wherein one or both of the mobile station (MS) and the base stations (BS1 and BS2) is provided with a unit for notifying information of a frame position with the possibility of transmission of packets based on detection of deterioration of a reception quality and wherein the mobile station (MS) is provided with a unit for determining a frame position without the possibility of transmission of packets and shifting to a peripheral cell detection mode at this frame position based on information of a frame position with the possibility of transmission of packets, whereby it is possible to shift to a peripheral cell detection mode without lowering the transmission efficiency and without complicating the processing.
