METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING FRAME ON THE BASIS OF FREQUENCY SELECTION TRANSMISSION
摘要
Provided is a method for transmitting a data frame through a channel including a plurality of sub-channels by a sender in a wireless local area network (WLAN) system. The method comprises the steps of: acquiring first channel state information on each of the plurality of sub-channels from a first receiver; allocating at least one first allocation sub-channel of the plurality of sub-channels to the first receiver on the basis of the first channel state information; acquiring second channel state information on each of the plurality of sub-channels from a second receiver if the at least one first allocation sub-channel corresponds to a portion of a plurality of channels; allocating at least one second allocation sub-channel of the plurality of sub-channels to the second receiver on the basis of the second channel state information; and transmitting a data unit to the first receiver and the second receiver. The data unit includes a first data frame and a second data frame, wherein the first data frame is transmitted through the at least one first allocation sub-channel, and the second data frame is transmitted through the at least one second allocation sub-channel.
