Abstract:
1. A sensing aiding method for cognitive radio, comprising: a high level node transmitting configuration information to a base station; the high level node receiving a result of a sensing measurement from the base station, wherein the result of the sensing measurement is corresponding to the configuration information; wherein the configuration information comprises the information of White Spaces (WS) resources of the base station, co-channel, and adjacent-channel system information of the WS; the high level node formulating a corresponding WS allocation policy according to the received result of the sensing measurement; wherein formulating the corresponding WS allocation policy when the WS resources of the base station which are allocated are unavailable comprises: when the base station continues using the WS resources of the base station which are allocated, the high level node coordinating an interference source related by the frequency spectrum allocation policy formulated by the high level node according to the information of the interference source provided by the result of the sensing measurement; the high level node transmitting new information of the WS resources to the base station and when an interference on the WS is an unexpected interference and the information of the interference source indistinguishable, the high level node storing the information of the interference source and reducing a priority level for allocating resources on the base station in subsequent resources allocation.
