Channel competition method and related device

Abstract

The invention provides a channel competition method for multi-link equipment and a related device. The method comprises the following steps: when a first station and a second station of the multi-link equipment perform channel competition according to a first EDCA parameter, the first station performs EDCA access, and the second station performs PIFS access, the first station and the second station generate a PIFS access counter. Before the PIFS access counter is withdrawn to 0, the first station and the second station perform channel competition according to the second EDCA parameter. Therefore, by designing the parameters in the second EDCA parameter set, the difficulty of successful access of the AP1 and the AP2 to the channel is increased, the probability of successful access of other network equipment to the channel is improved, and the fairness problem in the access process of multiple channels is improved. The embodiment of the invention can be applied to a wireless local area network system supporting an IEEE (Institute of Electrical and Electronic Engineers) 802.11 next-generation WiFi EHT (Wireless Fidelity EHT) protocol, such as 802.11 protocols such as 802.11 be.

Description

technical field [0001] The present application relates to the technical field of wireless local area networks, and in particular to a channel competition method and related devices. Background technique [0002] In order to improve data transmission efficiency, a wireless network device can transmit data through multiple channels. For example, a multi-link device (Multi-link device, MLD) can transmit data on multiple channels through multiple links. Or in the scenario of multi-main channel communication and multi-slice communication, a wireless network device can also transmit data on multiple channels. [0003] When a wireless network device needs to transmit data through multiple channels, it needs to compete for the multiple channels and obtain the right to use the multiple channels. [0004] A related art provides a channel contention scheme for multi-link devices performing multi-link communication. At least one AP of the multi-link device accesses the channel when t...

Problems solved by technology

However, wireless network devices that need to use channels in this frequency domain to transmit data and cannot transmit data on multiple channels at the same time still need to back off to 0 in the backoff window before they can access the channel.

In this way, in the process of channel competition, it is unfair to these wireless network devices that cannot transmit data on multiple channels at the same time
