Abstract
Methods and apparatus for transmission opportunity limits, backoff procedures, uplink random access related to uplink multi-user transmission in a High Efficiency WLAN (HEW) are described. An embodiment is a method for performing a frame exchange sequence including an uplink multi-user (UL MU) transmission by an access point (AP) in a wireless local area, the method including acquiring a transmission opportunity (TXOP) for initiating the frame exchange sequence; determining if a time required for the frame exchange sequence not including a control response frame exceeds a TXOP limit; and transmitting a trigger frame to one or more stations (STAs) when the time required for the frame exchange sequence not including the control response frame does not exceed the TXOP limit.
