Abstract
Control information communicating apparatus and method in Broadband Wireless Access (BWA) system are provided. A Base Station (BS) includes a manager for managing UL control region allocation information of adjacent BSs; a scheduler for scheduling resources and controlling periodic transmission of UL control region allocation information when a UL control region of the BS is the same as UL control regions of the adjacent BSs; and a control information generator for periodically generating the UL control region allocation information under the control of the scheduler.
Claims21
A Base Station (BS) in a Broadband Wireless Access (BWA) system, comprising:
- a manager for managing UpLink (UL) control region allocation information of adjacent BSs;
- a scheduler for scheduling resources and controlling periodic transmission of UL control region allocation information when a UL control region of the BS is the same as UL control regions of the adjacent BSs, and for controlling allocation information transmission of an initial ranging region in every frame and periodic transmission of UL control region allocation information of the remaining control regions when any one of the adjacent BSs has a different UL control region;
- and
- a control information generator for periodically generating UL control region allocation information under the control of the scheduler.
A Base Station (BS) in a Broadband Wireless Access (BWA) system, comprising:
- a manager for collecting UpLink (UL) control region allocation information from adjacent BSs and generating a broadcasting message which includes the UL control region allocation information of the adjacent BSs;
- and
- a transmitter for broadcasting the broadcasting message fed from the manager;
- a scheduler for controlling periodic transmission of UL control region allocation information of the BS when a UL control region of the BS is the same as UL control regions of the adjacent BSs, and for controlling allocation information transmission of an initial ranging region in every frame and periodic transmission of UL control region allocation information of the remaining control regions when any one of the adjacent BSs has a different UL control region;
- and
- a control information generator for periodically generating UL control region allocation information under the control of the scheduler.
A communicating method of a Base Station (BS) in a Broadband Wireless Access (BWA) system, the method comprising:
- collecting UpLink (UL) control region allocation information from adjacent BSs;
- and
- when a UL control region of the BS is the same as UL control regions of the adjacent BSs, periodically transmitting UL control region allocation information,
- when any one of the adjacent BSs has a different UL control region than the UL control region of the BS, controlling allocation information transmission of an initial ranging region in every frame and periodically transmitting UL control region allocation information of the remaining control regions.
A communicating method of a Base Station (BS) in a Broadband Wireless Access (BWA) system, the method comprising:
- collecting UpLink (UL) control region allocation information from adjacent BSs;
- generating a broadcasting message which includes the UL control region allocation information of the adjacent BSs;
- broadcasting the generated broadcasting message;
- controlling periodic transmission of UL control region allocation information of the BS when a UL control region of the BS is the same as UL control regions of the adjacent BSs;
- controlling allocation information transmission of an initial ranging region in every frame and periodic transmission of UL control region allocation information of the remaining control regions when any one of the adjacent BSs has a different UL control region;
- and
- periodically generating UL control region allocation information under the control of the scheduler.
