Abstract: An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random-access resource units (RUs) to only the selected BSS, and may transmit, for each of the selected BSSs, a respective frame indicating the random-access RUs allocated to that BSS. Wireless devices belonging to the selected BSS may contend for access to the random-access RUs allocated by the frame, and then transmit uplink data using the random-access RUs.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus obtain a signal from a remote wireless node. The apparatus may switch between a first mode and a second mode in response to the signal. The apparatus may sense the shared transmission medium and sense if an absence of traffic is detected. The apparatus may delay data transmission for a fixed time interval from detecting the absence of traffic. The apparatus may initiate the data transmission at the end of the fixed time interval if operating in the first mode or initiate the data transmission at the end of a random time interval following the fixed time interval if operation in the second mode.

Abstract: Methods and apparatus for managing reuse of a wireless medium are provided. One method of managing reuse of a wireless medium includes determining, at an access point, whether to allow reuse of the wireless medium by one or more stations in a basic service set (BSS). The method further includes transmitting, upon determining to allow reuse, an indication that reuse of the wireless medium can be permitted for stations meeting a criteria. The method further includes determining one or more reuse parameters. The method further includes transmitting the one or more reuse parameters.

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: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a hybrid automatic repeat request (HARQ) protocol in a wireless local area network (WLAN). A station (STA) may send a HARQ transmission to another STA. The HARQ protocol may support the use of different types of feedback from the receiving STA to control the HARQ retransmission process. This disclosure provides example message formats to support HARQ transmission and HARQ feedback in a WLAN.
