    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 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.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an AP that requests a plurality of STAs to jointly enable and disable an MRP based on at least one of that each STA of the STAs has uplink traffic with the AP or that each STA of a subset of the STAs has a hidden node. The AP receives, from the STAs, information indicating a communication metric while jointly enabling or disabling the MRP. The AP determines, based on the received information indicating the communication metric, whether the joint enablement of the medium reserving procedure improves communication for the plurality of STAs. The AP requests the STAs to jointly enable the medium reserving procedure for subsequent communication when the joint enablement of the medium reserving procedure improves communication for the plurality of STAs.

    Abstract: Aspects of the present disclosure provide various mechanisms for protection of MU transmissions, such as UL MU MIMO and UL OFDMA. The mechanisms may allow for various NAV setting options for UL MU MIMO or UL OFDMA. Aspects of the present invention relate to a processing system configured to generate a first frame configured to trigger multiple transmissions from multiple devices, wherein the first frame has a duration field set to a value corresponding to a duration that covers at least the multiple transmissions, and an interface configured to output the frame for transmission

    Abstract: Systems and methods for allowing group access to the wireless medium of a wireless network are disclosed. In one aspect, the method includes performing a backoff procedure for each of one or more certain classes. The method may further include receiving an indication that the backoff procedure for at least one of the one or more certain classes is complete. In some aspects, once the backoff procedure for a class is completed, performing one or more transmissions which are transmittable simultaneously with other transmissions in the class. Finally, the method may update the backoff procedures for the class based on the one or more transmissions. In some aspects, the backoff procedures may be updated based on certain fairness conditions.
