Abstract

An embodiment of the present invention provides a method for selecting a channel and a sending end. The method includes: sorting a plurality of channels, and generating a backoff count value; starting from the initial time slot, in each time slot, according to the sorting order, and according to the busy / idle state of each channel, the backoff count value is sequentially decremented until the backoff count value is 0; according to the result of decrementing the backoff count value and the multiple The busy / idle state of at least one of the channels, and the channel used by the sender to send data is selected from the multiple channels. The method and the sending end can improve channel utilization.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a channel selection method and a sending end. Background technique [0002] A wireless fidelity (English: Wireless Fidelity, WiFi for short) system can work in a scenario of multiple channels / sub-channels. For the multi-channel scenario, a channel selection method for maintaining multiple backoff counters on multiple channels is currently proposed. Suppose the system has a total of N channels, and each channel corresponds to a backoff counter. When a station (English: station, referred to as: STA) or an access point (English: Access Point, referred to as: AP) has data to send, the STA or AP will Carry out the following process to select the channel for data transmission: randomly generate the backoff count value of the backoff counter on each channel, and simultaneously perform carrier sense multiple access (English: Carrier Sense Multiple Access, CSMA for short) on each c...
