Abstract

The invention relates to the field of wireless communication, in particular to a channel detection technology in a wireless communication system. In the full duplex channel detection method, an access point (AP) generates channel detection information, the channel detection information at least comprising: identification information of a first station (STA) and a link state of the first STA, and identification information of a second STA and a link state of the second STA; wherein the link state of the first STA is an uplink sending state, and the link state of the second STA is a downlink receiving state; the AP sends channel detection information; the STA determines a link state corresponding to the STA according to the channel detection information; furthermore, the AP and the STA which determines the link state of the AP carry out detection of a full-duplex channel and a mutual interference channel respectively. Through the scheme provided by the invention, the detection of the full-duplex channel is realized, so that the elimination of self-interference and mutual interference is facilitated, and the throughput and transmission efficiency of the system are improved.

Description

[0001] This application is a divisional application of a Chinese patent application with the application number 201711068596.9, the application date is November 03, 2017, and the invention title is "a method and device for channel detection". technical field [0002] The present application relates to the field of wireless communication, in particular to the channel detection technology in the wireless communication system. Background technique [0003] In recent years, due to the exponential increase of wireless devices and the scarcity of wireless spectrum resources, both academia and industry are looking for ways to improve the efficiency of wireless spectrum utilization. Full-duplex (Full Duplex, referred to as FD) wireless communication technology can enable users with different transmission directions in the uplink and downlink to transmit simultaneously on the same wireless channel. duplex mode, time-division duplex mode) to double the spectrum utilization, so full-du...
