Abstract: In wireless communications for multi-users, a station may generate a first frame and transmit the first frame to an access point. The first frame may include media access control protocol data units (MPDUs). Each MPDU is associated with a traffic identifier (TID). In one aspect, a TID of one of the MPDUs is different from a TID of another one of the MPDUs. In response to receiving the first frame, the access point may generate a second frame based on the first frame. The second frame may include an indication that all of the MPDUs having TIDs are received. The access point may transmit the second frame to the station. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: The embodiments provide a method implemented by a network device for transmitting link adaptation feedback in a Wireless Local Area Network (WLAN) that supports multi-user simultaneous transmission. The method generates and transmits a frame that includes one or more link adaptation feedback values associated with a wireless communications link between the network device and a second network device. In one aspect, the one or more link adaptation feedback values may include a link adaptation feedback value for an entire operation bandwidth of the wireless communications link and a link adaptation feedback value for a given subchannel within the operation bandwidth. In another aspect, link adaptation feedback values for one or more users of a multi-user simultaneous transmission are transmitted in a multi-user acknowledgment (ACK) frame. The embodiments allow for efficient link adaptation in a multi-user simultaneous transmission environment.
