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.

1. A wireless communications system for performing a packet communication between a plurality of mobile stations and a base station, the wireless communications system comprising:
a base station including a transmitting unit that transmits into notifying a specific mobile station among the plurality of mobile stations of a plurality of wireless frames with a possibility of a packet transmission toward the specific mobile station, and a mobile station including a determination unit that determines a frame as a first determined frame with the possibility of the packet transmission to the mobile station which is positioned from a frame that is notified as a frame with the possibility of start of transmission of packets to the mobile station and packet transmission to the mobile station is actually carried out to another frame which satisfies a predetermined condition, determines a frame, after satisfying the predetermined condition, as a second determined frame without the possibility of a packet transmission to the mobile station, and shifts to a peripheral cell detection mode at the second determined frame.
