Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0029] figure 1 It is a schematic diagram of the structure of the basic service set. Such as figure 1 As shown, an AP and multiple STAs associated with the AP form a BSS. exist figure 1 Among them, there are three STAs associated with this AP: STA1, STA2 and STA3.

[0030] Figure 2A It is an architecture diagram of a wireless network currently used in joint transmission. Such as Figure 2A As shown, it is assumed that AP1 and STA1 form a BSS, and AP2 and STA2 form a BSS. AP1 and AP2 form a joint transmission group through negotiation or configuration. STA1 is within the overlappin...

Abstract

The invention provides a data transmission method and device and a storage medium, and the method comprises the steps that a first communication node transmits a wireless frame comprising indication information to a second communication node, wherein the second communication node is associated with a third communication node, the third communication node and the first communication node carry outthe joint transmission, the indication information is used for indicating a fourth communication node except the second communication node to determine whether to perform channel competition or not according to the indication information after receiving the wireless frame, sending the wireless frame including the indication information to the second communication node through the first communication node, and in a scene where the first communication node and the third communication node perform joint transmission, after the fourth communication node except the second communication node receives the wireless frame, determining whether channel competition is carried out according to the indication information, so that energy of the fourth communication node is saved, the second communicationnode is prevented from being interfered to receive the wireless frame, and the communication reliability of the second communication node is improved.

Description

technical field [0001] The present application relates to a wireless communication network, in particular to a data transmission method, device and storage medium. Background technique [0002] Currently, in the field of wireless networks, wireless local area networks (Wireless Local Area Networks, WLAN) develop rapidly. At the same time, users' demand for coverage is increasing day by day, their requirements for service quality are getting higher and higher, and their requirements for throughput are also getting higher and higher. An Access Point (abbreviated as AP) and multiple stations (abbreviated as STA) associated with the AP form a Basic Service Set (abbreviated as BSS). In order to provide more reliable and higher-speed services to users at the edge of coverage, multiple access points can simultaneously transmit jointly to the same site. [0003] Assume that AP1 and STA1 form a BSS, and AP2 and STA2 form a BSS. In order to allow the station STA1 at the coverage ed...
