The present invention provides an energy detection and channel quality detection-based spectrum perception method and a base station. The method comprises the following steps: receiving a cognitive resource configuration message sent from a cognitive resource management center by the base station; detecting the energy of a to-be-sensed frequency band in the cognitive resource configuration message to obtain detected resources in the to-be-sensed frequency band; allocating the detected resources to a plurality of detection terminals; sending a paging message to each detection terminal, wherein the paging message contains the position information of the allocated detected resources corresponding to the above detection terminal in the to-be-sensed frequency band and the sending time information of at least one detection signal; at the sending time of the at least one detection signal, sending the detection signal to the plurality of detection terminals; receiving the reception quality information of the at least one detection signal reported by the plurality of detection terminals; according to the reception quality information of the at least one detection signal, making an availability decision on the detected resources by the base station. Therefore, an availability decision-making result for the detected resources is obtained.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a spectrum sensing method based on energy detection and channel quality detection and a base station. Background technique [0002] With the rapid development of wireless communication technology, spectrum resources are becoming increasingly tight. Especially with the development of wireless local area network (Wireless Local Area Networks, WLAN) technology and wireless personal area network (Wireless Personal Area Networks, WPAN) technology, more and more people access the Internet wirelessly through these technologies. Most of these network technologies work in unlicensed frequency bands. Due to the rapid development of WLAN and WRAN wireless communication services, the unlicensed frequency bands where these networks work have gradually become saturated. And some other communication services (such as TV broadcasting services, etc.) require a certain protection ...
