Abstract: A method for transmitting a frame is provided by a device in a wireless communication network. The device compensates a carrier frequency using a value of carrier frequency offset (CFO), and transmits a frame with the compensated carrier frequency to a receiver. The value of the CFO is indicated in TXVECTOR. A method for transmitting a frame is provided by a device in a wireless communication network. The device allocates data tones for a last symbol based on a payload size, generates the last symbol having repeated waveforms and transmits a frame including at least one period waveform of the repeated waveforms in the last symbol.

Abstract: Disclosed herein is a method performed by a station (STA) in a wireless network to access a non-primary channel. The method includes determining a maximum supportable bandwidth of a primary transmission opportunity (TXOP) established in a primary channel, responsive to a determination that the maximum supportable bandwidth of the primary TXOP is smaller than a maximum supportable bandwidth of the STA, establishing a secondary TXOP in the non-primary channel, and transmitting a data frame to a second STA during the secondary TXOP in the non-primary channel.
