    Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a first user terminal. The first user terminal receives, on a first DL communication channel of multiple DL communication channels, a DL MU PPDU includes MPDUs transmitted from an access point to multiple user terminals including the first user terminal on the multiple DL communication channels. The first user terminal obtains an UL channel indication and a BA indication. The first user terminal transmits, on a first UL communication channel of multiple UL communication channels, a first BA to the access point based on the UL channel indication and the BA indication simultaneously or concurrently with a BA transmission from the rest of the multiple user terminals to the access point on the rest of the multiple UL communication channels. The first BA acknowledges one or more of the MPDUs.

    Abstract: A method of wireless communication by a first user terminal is described as well as the first user terminal. The method comprising receiving, from an access point, a downlink, DL, multi-user, MU, physical layer convergence protocol, PLCP, protocol data unit, PPDU (512), and a block acknowledgement, BA, trigger, wherein the DL MU PPDU (512) includes: a first aggregate medium access control, MAC, protocol data unit, A-MPDU (513), and an acknowledgement policy (526) that instructs the first user terminal when to transmit a BA to the access point, wherein the first A-MPDU (513) includes a plurality of MPDUs and transmitting, to the access point, a first BA (516) based on the BA trigger and the acknowledgement policy (526), wherein the first BA (516) acknowledges one or more MPDUs of the plurality of MPDUs.

    Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the example method may include receiving a data frame including a Medium Access Control, MAC, header or a physical layer, PHY, header, wherein the MAC header or the PHY header of the data frame includes transmit power related information corresponding to a second device. The transmit power related information includes at least one of a maximum transmit power, a power backoff per modulation and coding scheme, MCS, information, or an actual transmit power. The example method further includes selecting, by the first device based on the transmit power related information, a first modulation and coding scheme for scheduling an uplink transmission with the second device in accordance with the first modulation and coding scheme.

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for improving transmission opportunity (TxOP) truncation in wireless communication. In some implementations, a transmit opportunity (TxOP) period truncation or whether to update a network allocation vector (NAV) timing based on a message that includes transmitter and receiver information (such as a transmitter address (TA) and a receiver address (RA)) may be determined. For example, a station may receive a contention-free end (CF-End) frame and determine a TxOP period truncation based on comparing a TA and an RA included in the CF-End frame with a TA and an RA included in an earlier received message (e.g., an RTS). Such information may be compared to other TAs or RAs associated with NAV timing values and the NAV timing may be set, reset, updated, or canceled based on the comparison.

    Abstract: A method for wireless communication is provided. The method comprises transmitting a first wireless message comprising a request for a first user terminal to transmit uplink data and an indication of at least one requested operational parameter. The method also comprises receiving a second wireless message from an access point in response to the first wireless message, the second wireless message indicating whether a plurality of user terminals including the first user terminal is selected to transmit uplink data, the second wireless message indicating at least one operational parameter for transmission of uplink data based on the at least one requested operational parameter.
