Problems solved by technology

After NSTR MLD sends a physical layer protocol data unit (Physical Protocol Data Unit, PPDU) on one link, the sent PPDU will affect the channel monitoring on another link, so another link cannot transmit PPDU

Abstract

The embodiment of the invention discloses a channel interception method and a related device, which can avoid the influence of the sending action of other links on the channel interception result by adjusting the channel interception time, thereby realizing the link error recovery in a communication scene in which NSTR MLD (Non Short Term Rate Multilink Device) cannot be simultaneously transmitted and received. The method is applied to an NSTR MLD, the NSTR MLD comprises a first station STA and a second station STA, the first STA transmits a first frame on a first link, and the second STA transmits a second frame on a second link; the NSTR MLD determines transmission failure of at least one of the first frame and the second frame; the first STA performs channel interception at a first inter-frame interval after the first frame ends, the time length of the first inter-frame interval being less than or equal to the time length of a point coordination function inter-frame interval (PIFS), or the second STA performs channel interception at a second inter-frame interval after the second frame ends, and the time length of the first inter-frame interval is less than or equal to the time length of the point coordination function inter-frame interval (PIFS). The time length of the second inter-frame interval is greater than or equal to the time length of the short inter-frame spacing (SIFS) and less than or equal to the time length of the PIFS.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a channel sensing method and a related device. Background technique [0002] Wireless local area network (Wireless Local Area Network, WLAN), commonly known as wireless high-fidelity (Wireless-Fidelity, Wi-Fi) communication network, the standard adopted is the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11 series standard. The 802.11be has currently passed the definition of a multi-link device (Multi-link Device, MLD), that is, a device supporting multi-link communication. There are multiple access points (Access Point, AP) or stations (Station, STA) in each MLD device to form an AP MLD or a STA MLD, and the communication between the MLDs is multi-link communication. [0003] 802.11be defines that a multi-link device has a simultaneous transmitting and receiving (STR) capability, or a non-s...
