Mobile station for transmitting reception quality information during handover

摘要

In a wireless communication system wherein mobile stations (7) to be transmitted to are selected successively from a plurality of transmission destination candidate mobile stations and data transport to the selected mobile station (7) is performed via a shared channel, each mobile station transmits reception quality information for signals received from the wireless base station and receives data which is transmitted via a downlink channel by the wireless base station based on the reception quality information. The mobile station (7) comprises a detection unit which detects that handover processing is being performed, and a control unit which, upon the detection, provides control such that reception quality information is not transmitted if its transmission timing is before changeover of the downlink channel due to the handover processing, but the transmission timing of the data transmitted via the downlink channel from the wireless base station based on the reception quality information is after the channel changeover. The occurrence of problematic data portions during handover is thus prevented.
