Abstract

The present application relates to the field of wireless communication, in particular to the channel detection technology in the wireless communication system. In a full-duplex channel detection method, an access point AP (Access Point) generates channel detection information, wherein the channel detection information includes at least: the identification information of the first station STA (Station) and the link status of the first STA , and, the identification information of the second STA and the 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 its own corresponding link state according to the channel detection information; further, the AP and the STA which knows its own link state respectively perform full-duplex channel detection and mutual interference channel detection. Through the solution provided in this application, full-duplex channel detection is realized, so as to eliminate self-interference and mutual interference, which is beneficial to improving system throughput and transmission efficiency.

Description

technical field [0001] The present application relates to the field of wireless communication, in particular to the channel detection technology in the wireless communication system. Background technique [0002] 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-duplex technology is one of the potential technologies of the next generation of WiFi. Due to the same frequency of sending and receiving at the same time, the difficulty in realizing the full-duplex technology is the self-interference eliminatio...
