Abstract
A base station sends to a target base station a switching request which contains a time slot used in communication with a mobile station. The base station allocates to the mobile station at least one idle communication channel included in time slots different from the time slot contained in the switching request received from the base station.
Claims7
A mobile communication system including a first base station device, a second base station device, and a mobile station device for carrying out simultaneous communication with the first base station device and the second base station device, in which at least one communication channel composed of a combination of any time
- slot according to time division multiple access and any subchannel according to orthogonal frequency division multiple access is used in the communication, wherein
- the first base station device comprises means for notifying the second base station device of a time slot used in the communication with the mobile station device, and
- the second base station device comprises means for allocating to the mobile station device at least one idle communication channel included in time slots different from the time slot notified by the first base station device.
A base station device for carrying out communication with a mobile station device, using at least one communication channel composed of a combination of any time slot according to time division multiple access and any subchannel according to orthogonal frequency division multiple access, comprising:
- means for receiving notification from another base station device of a time slot used by the other base station device in communication with the mobile station device;
- and
- means for allocating to the mobile station device at least one idle communication channel included in time slots other than the time slot notified by the other base station device.
A channel allocation method for a base station device for carrying out communication with a mobile station device, using at least one communication channel composed of a combination of any time slot according to time division multiple access and any subchannel according to orthogonal frequency division multiple access, the method comprising:
- a step of receiving notification from another base station device of a time slot used by the other base station device in communication with the mobile station device;
- and
- a step of allocating to the mobile station device at least one idle communication channel included in time slots other than the time slot notified by the other base station device.
