Embodiment Construction

[0046] figure 1It is a schematic diagram of data transmission between two devices that do not support multi-link simultaneous sending and receiving. Taking the establishment of two links between two devices as an example, they are the first link link1 between the first station STA1 and the first access point AP1, and the link link between the second station STA2 and the second access point AP2. The second link link2.

[0047] Such as figure 1 As shown, in the prior art, it is assumed that the first station STA1 is the holder of the transmission opportunity (Transmission Opportunity, TXOP) on the first link link1, that is, on the first link link1, the first station STA1 first sends An access point AP1 sends data.

[0048] Before the start time t0 of the TXOP, if the second station STA2 monitors that the channel corresponding to the second link link2 is idle, the second station STA2, as the holder of the TXOP on the second link link2, can Data transmission synchronized with ...

Abstract

The invention discloses a multi-link data transmission method, a station, an access point and a readable storage medium. The method is suitable for data transmission between two devices which do not support simultaneous transmission and reception of multiple links, and comprises the following steps: monitoring a channel state corresponding to a second link within the duration of a transmission opportunity TXOP on a first link; and when the channel corresponding to the second link is monitored to be in an idle state, starting data transmission synchronized with the first link on the second link. By applying the scheme, the channel utilization rate can be effectively improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-link data transmission method, a station, an access point and a readable storage medium. Background technique [0002] In a wireless local area network (Wireless Local Area Network, WLAN), the IEEE802.11be standard under discussion and formulation includes standard formulation of a multi-link system. One physical device may include multiple stations (stations, STAs), and the multiple STAs Corresponding to different physical layers (Physical Layer), but corresponding to the same media access control (Media Access Control Address, MAC) layer. One physical device may also include multiple access points (Access Point, AP), and the multiple APs respectively correspond to different physical layers, but correspond to the same MAC layer. Multiple links can be established between a physical device with multiple STAs and a physical device with multiple APs to implem...
