METHOD AND APPARATUS FOR DIRECTING A CHANNEL IN A WIRELESS LAN

摘要

The present invention relates to a method and apparatus for indicating a channel in a wireless local area network (WLAN). A transmitting station generates and transmits a physical protocol data unit (PPDU) including a preamble field and a data field, and a high efficiency signal field (HE-SIG-A) of the preamble field includes a bandwidth An identifier and a channel combination identifier, and the channel combination identifier is used to indicate whether the data transmission channel is continuous in the frequency domain. In the manner described above, discontinuous channels in the frequency domain are indicated in wireless local area networks, available data transmission channels are improved, and system throughput is increased.
