Abstract

Embodiments of the present invention provide a multi-channel contention method, communication equipment and a wireless network system. The present invention is applied to a communication device of a wireless network, and the communication device is an access point AP or a station STA; the communication device includes: a channel competition module for listening to at least two channels; determining the first channel that competes successfully, And, determine the second channel that is regarded as a successful competition; an interaction module, configured to exchange control frames with other communication devices in the wireless network through the first channel and the second channel to occupy channels, or exchange data frames . The embodiment of the present invention solves the problem that the success rate of multi-channel competition is low and a large amount of bandwidth is wasted.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a multi-channel contention method, communication equipment and a wireless network system. Background technique [0002] In the existing mechanism specified by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, the peak rate of data transmission is increased by increasing the transmission bandwidth by dividing channels into primary channels and secondary channels. This mechanism is similar to carrier aggregation (CarrierAggregation, CA for short), and communication devices need to first compete for access on the main channel. The order of priority for channel competition access is the main channel, the auxiliary 20 MHz (Mega Hertz, MHz) channel, the auxiliary 40 MHz channel, and the auxiliary 80 MHz channel. Only when the previous channel in the above sequence allows access, the communication device will compete for the latter ...
