METHOD AND DEVICE FOR ALLOCATING CHANNEL RESOURCES OF WLAN AND WIRELESS LOCAL AREA NETWORK COMMUNICATION SYSTEM

摘要

The present invention provides a method and device for allocating WLAN channel resources and a wireless local area network communication system. The method includes: obtaining subcarrier allocation information, where the subcarrier allocation information is used to identify a subcarrier or a subcarrier group used to bear data, where channel quality of a subchannel where the subcarrier or the subcarrier group is located is greater than or equal to a judgment threshold; and sending data on the subcarrier according to the subcarrier allocation information. The present invention reduces a waste of transmit power of a station, and can increase a modulation order because no restriction is imposed by pull-down of a subchannel with very poor channel quality
