Abstract

The embodiment of the invention provides a full duplex data transmission method and device, and the method comprises the steps that an access point transmits a first signal to at least one first station, wherein the first signal comprises information for indicating at least one full duplex TXOP; the access point sends a first data frame to the first station according to the first signal; the access point receives a second data frame sent by at least one second station, wherein the transmission time interval of the first data frame and the second data frame is included in the same full duplex TXOP in the at least one full duplex TXOP, and a non-null intersection exists in the transmission time interval of the first data frame and the second data frame. Full-duplex transmission between the access point and the station is realized, the problem that the access point sends downlink data independently due to the fact that the station does not know that full-duplex transmission is about to becarried out between the access point and the station is avoided, and the problem of resource waste is avoided.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a full-duplex data transmission method and device. Background technique [0002] With the development of wireless communication technology, wireless communication equipment will penetrate into all aspects of production and life. With the exponential increase of wireless devices and the scarcity of wireless spectrum resources, it is very important to improve the efficiency of wireless spectrum utilization. A full duplex (full duplex, FD) wireless communication technology can enable users with different uplink and downlink transmission directions to transmit data simultaneously on the same wireless channel. The duplex wireless communication technology can provide spectrum efficiency, and is one of the potential technologies of next generation (next generation, NG) wireless broadband (wireless fidelity, WiFi). [0003] In the prior art, an access point (access ...
