Abstract: In wireless communications, an access point may decrement multiple backoff counters. Each backoff counter may be associated with a respective access function. A first access function may be associated with downlink transmission of data of a first access category. A second access function may be associated with downlink transmission of a trigger frame for facilitating uplink multi-user transmission. The AP may transmit at least one of a first downlink frame or a trigger frame based at least on the decremented backoff timer associated with the first and second access functions. A station may receive the first downlink frame or the trigger frame. If the trigger frame is received, the station may transmit a second frame to the AP based on an indication of an access category contained in the trigger frame. Other methods, apparatus, and computer-readable media are also disclosed.

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.
