METHOD AND APPARATUS FOR ALLOCATING TRANSMISSION CHANNEL IN WIRELESS LOCAL AREA NETWORK SYSTEM

摘要

According to one embodiment, a method for a wireless local area includes: generating a medium access control (MAC) protocol data unit (MPDU) to be transmitted to a target station; generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) by attaching a PLCP preamble to the MPDU; selecting a transmission channel; and transmitting the PPDU to the target station over the transmission channel. Selecting the transmission channel includes: performing clear channel assessment (CCA) on a first channel to determine whether the first channel is idle; and only after it is determined that the first channel is idle, selecting the first channel and at least one idle second channel as the transmission channel. The PLCP preamble includes channel allocation information indicating a bandwidth of the transmission channel.

1. A method for a wireless local area network, the method performed by a station comprising:
receiving a requesting frame from an access point (AP), the requesting frame including channel allocation information indicating a plurality of allocated channels to be used by the station to transmit a physical layer protocol data unit (PPDU) as a response to the requesting frame; performing clear channel assessment (CCA) on the plurality of allocated channels to determine whether the plurality of allocated channels are idle; and only if all of the plurality of allocated channels are idle, transmitting the PPDU to the AP as a response to the requesting frame through the plurality of allocated channels.
