Embodiment Construction

[0157] The present application provides an FD transmission method and related equipment, which are used for the first network equipment to accurately acquire the state information of the self-interference channel before performing FD transmission.

[0158] First, before introducing this application in detail, first introduce the network device with FD capability involved in this application.

[0159] In traditional network equipment, half-duplex (half duplex, HD) technology is generally used, that is, network equipment with HD capabilities can only perform one-way transmission at the same time, and cannot send signals when it is in the receiving state, or when sending Cannot receive signal while in state.

[0160] In the proposed or adopted FD technology, network equipment with FD capability can realize two-way transmission at the same time and at the same frequency, and can also send signals when in the receiving state, or receive signals when in the sending state. signal, t...

Abstract

The embodiment of the present application discloses a full-duplex FD transmission method and related equipment, which are used for the first network equipment to accurately acquire the status information of the self-interference channel before performing FD transmission. A full-duplex FD transmission method provided by an embodiment of the present application includes: the first network device obtains the state information of the self-interference channel according to the first signal and the second signal, wherein the first signal is training for self-interference channel estimation sequence, the second signal is a signal received by the first network device through the self-interference channel of the first signal; the first network device performs FD transmission.

Description

technical field [0001] The present application relates to the field of data transmission, in particular to a full-duplex FD transmission method and related equipment. Background technique [0002] A full duplex (full duplex, FD) technology enables a network device to simultaneously receive and send data on network resources such as the same time or frequency. For example, in a wireless local area network (wireless local area network, WLAN), an access point (access point, AP) or station (station) with FD capability often simultaneously transmits a physical layer protocol data unit (physical protocol data unit, PPDU) data packet receiving and sending. [0003] Network equipment often has self-interference problems in FD transmission, that is, the PPDU data packets sent by the network equipment to the outside world will return to the network equipment through the self-interference channel, thereby forming interference signals, and the PPDU data packets received by the network ...
