Abstract
A method for communication in a wireless local area network comprises receiving, at a first device, a control frame from a second device. The method further comprises determining, by the first device using the control frame, a channel state information (CSI) for each of a plurality of sub bands of a bandwidth of the control frame, and allocating, by the first device to the second device, one or more sub bands from the plurality of sub bands based on the determination, the one or more sub bands to be allocated to the second device for transmitting data to the second device from the first device via an Orthogonal Frequency Division Multiple Access (OFDMA) frame.
