Problems solved by technology

When the 20MHz main channel is occupied, other secondary channels cannot be used even if they are idle
The heavy dependence on the main channel under large bandwidth transmission makes the channel utilization rate not high

Embodiment Construction

[0064] The "first", "second" and so on (if any) mentioned in the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence.

[0065] Access point (Access Point, AP): Based on the 802.11 protocol, it provides a wireless access function for the station (Station). It is a bridge between wireless and wired networks, and it can also be called a "hot spot".

[0066] The access point involved in this application has the capability of multi-band and multi-radio. The access point has multiple sets of independent 802.11 chips, that is, each set of 802.11 chips can include an independent baseband processing module and a radio frequency module, thereby supporting multi-radio (Multi-radio) capability. Different radio frequency modules can work on different channels on the same bandwidth (band), and can also work on different bandwidths (band). A radio frequency module of the access point can alw...

Abstract

The embodiment of the invention provides a wireless communication method and device. The wireless communication method comprises the steps that a first access point sends a first transmission allocation frame to a station on a public control channel, the first transmission allocation frame is used for indicating the station to communicate with the first access point in a first time period of a first data channel, and the station communicates with the first access point in the first time period of the first data channel. The embodiment of the invention can improve the channel utilization rate.

Description

technical field [0001] The embodiments of the present application relate to wireless communication technologies, and in particular, to a wireless communication method and device. Background technique [0002] IEEE 802.11 is a common standard for wireless local area networks today, and it is a wireless network communication standard defined by the International Institute of Electrical and Electronic Engineering (IEEE). IEEE 802.11 adopts a Carrier Sense Multiple Access / Collision Avoidance (CSMA / CA) protocol with collision avoidance to implement distributed channel access. [0003] When using CSMA / CA, if a station senses that the channel is busy, it will back off for a random amount of time after the channel becomes idle again. This practice of always backing off for a random amount of time after another station occupies the channel avoids collisions between stations. However, as the number of stations increases and the deployment of access points (Access Point, AP) becomes ...
