Channel scheduling method and wireless communication device

Abstract

The invention discloses a channel scheduling method and a wireless communication device for distributing a master node in an ad hoc subnetwork. The method includes: in response to creating an ad hoc subnet, initially selecting a first wireless channel among multiple wireless channels as a working channel of the ad hoc subnet by a master node in the newly created ad hoc subnet, wherein the The multiple wireless channels include a priority wireless channel dedicated to transmitting priority data and non-priority wireless channels other than the priority wireless channel; the master node monitors and maintains co-channel interference indication values ​​of the multiple wireless channels; responding to The requirement for switching the working channel of the ad hoc subnet to the second wireless channel is that the master node performs the channel switching according to the maintained co-channel interference indication value, wherein the working channel of the ad hoc subnet is used for all communication of master nodes and / or slave nodes in the ad hoc subnet, wherein the ad hoc subnet is an area-restricted network defined by an area key.

Description

technical field [0001] The present invention relates to the field of wireless communication in general, and more specifically to a distributed channel scheduling method and wireless communication equipment in an ad hoc subnet environment. Background technique [0002] In the case of using dense wireless channels, in the WiFi802.11b / g or WiFi-Direct environment of 2.4G communication technology, the channels with non-overlapping frequency bands commonly used in office are the first channel (2412MHz), the sixth channel (2437MHz ), the eleventh channel (2462MHz), and in the developing 5G communication technology, there are 4 available channels from 5.725 to 5.825GHz. As the number of mobile devices sharing the same channel increases, the co-channel interference generated between these mobile devices also increases. Data transfer performance on this channel may not be guaranteed when important data needs to be transferred efficiently. [0003] In the U.S. patent application pub...

Problems solved by technology

[0006] However, the above existing technologies only involve the centralized channel scheduling of wireless channels by access point devices or independent devices, and none of them solve the needs of distributed channel scheduling in an ad hoc subnet environment, and need to A technology that uses existing resources as much as possible to perform distributed channel scheduling in the organization subnet environment
