The receiver can receive multiple RTS messages and in response, issue respective AFR messages, to thus perform RTS negotiation of resources for access by the stations. If the receiver fails to receive any further RTS messages due to, for example, collision of RTS messages sent by multiple stations or failure of any other stations to send an RTS message, the receiver can then issue a clear to send (CTS) message indicating to all stations that have sent an RTS message that they are clear to send to the receiver using the information contained in the AFR message. | 2010-02-04 |
| 20100027491 | UPLINK RESOURCE CONTROL - Apparatus for interference budgeting at base stations of a wireless network wherein mobile units communicate with a current base station but may cause interference to neighboring base stations, comprises: an extraction unit for extracting, from signals received at said current base station in relation to respective mobile units, an interference indication; and an uplink management unit for controlling the uplink to mobile units, wherein said management unit is connected to said extraction unit to obtain respective interference indications, thereby to use said respective interference indications as constraints when allocating said uplink resources. The resource may be uplink power or an uplink frequency channel that is allocated to different mobile stations and/or it may be interference budget that is allocated between base stations. | 2010-02-04 |
