Abstract:
1. A method for spectrum detection, comprising: receiving an intermediate spectrum detection result sent by a cooperative detection non-relay node and a cooperative detection relay node; and integrating the intermediate spectrum detection results to obtain a final spectrum detection result; wherein if the cooperative detection non-relay node performs spectrum detection and determines that the cooperative detection non-relay node is capable of reporting a detection result, the intermediate spectrum detection results comprise a first spectrum detection result of the cooperative detection non-relay node and a second spectrum detection result of the cooperative detection relay node; if the cooperative detection non-relay node performs spectrum detection, but is not capable of determining the detection result, and relays a detection signal to the cooperative detection relay node, the intermediate spectrum detection results comprise the second spectrum detection result of the cooperative detection relay node; and if the cooperative detection non-relay node performs spectrum detection, is capable of determining the detection result, but is not capable of reporting the detection result, the intermediate spectrum detection results comprise one of: the second spectrum detection result of the cooperative detection relay node; the first spectrum detection result relayed by the cooperative detection non-relay node and reported by the cooperative detection relay node; and the second spectrum detection result of the cooperative detection relay node and the first spectrum detection result relayed by the cooperative detection non-relay node.
