Abstract
The occurrence of problematic data portions during handover is prevented by a wireless base station in a wireless communication system wherein mobile stations to be transmitted to are selected successively from a plurality of transmission destination candidate mobile stations and data transport to the selected mobile station is performed via a shared channel, the wireless base station comprising a detection unit which detects mobile stations undergoing handover; and a control unit which provides control such that a mobile station detected by the detection unit becomes less likely to be selected as described above as compared to other mobile stations.
Claims7
A wireless base station in a wireless communication system wherein mobile stations to be transmitted to are selected in order from a plurality of transmission destination candidate mobile stations and data transport to the selected mobile stations is performed via a shared channel, the wireless base station comprising:
- a detection unit which detects a mobile station undergoing handover;
- and
- a control unit which provides control such that a mobile station detected by the detection unit becomes less likely to be selected as described above as compared to other mobile stations.
A mobile station which transmits reception quality information for signals received from a 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 comprising:
- a detection unit which detects that handover processing is being performed;
- and
- a control unit which, upon the detection, provides control such 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.
A mobile station which transmits reception quality information for signals received from a wireless base station, receives transmission alerts and corresponding data which are transmitted via a downlink channel bythe wireless base station based on the reception quality information, and transmits the reception result for the data, the mobile station comprising:
- a detection unit which detects that handover processing is being performed;
- and
- a control unit which, upon the detection, provides control such a reception result is not transmitted if its transmission timing is after changeover of the downlink channel due to the handover processing, but the transmission timing of the reception quality information used for transmitting data relating to the reception result indicated by the reception result is before the channel changeover.
