Abstract: Certain aspects of the present disclosure provide techniques that may allow a device participating in a setup procedure to efficiently propose a range of values for a negotiated parameter. The techniques may reduce setup time, for example, allowing a responder to accept a value within the proposed range which may eliminate overhead associated with some of the back and forth message exchange of typical negotiations.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for enabling a neighboring access point (AP) to reuse communication resources that are used by an existing spatial reuse group (SRG). In one aspect, an SR element including SR information can be generated. The SR information may indicate that a first group of STAs associated with a second AP may reuse resources of a wireless medium over which packets are transmitted by a second group of STAs associated with the first AP and may indicate a permitted OBSS threshold value for reuse of the resources over the first AP. In some implementations, a wireless apparatus may transmit the SR element that includes the SR information.

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: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for an AP. The AP determines a time duration associated with a validity of a first broadcast TWT parameter set associated with a broadcast TWT schedule identified by a first ID. The AP generates the first broadcast TWT parameter set to identify the determined time duration. The first broadcast TWT parameter set includes at least four bits identifying the determined time duration. The AP transmits a management frame including the generated first broadcast TWT parameter set. The time duration may indicate a number of intervals for which the first broadcast TWT parameter set is valid. Each interval of the intervals may be a beacon interval corresponding to a beacon frame, or may be a DTIM interval corresponding to a beacon frame that includes a DTIM.

Abstract: Features related to providing feedback corresponding to a portion of a data frame while another portion of the data frame is being received are described. In an aspect, a first device may transmit, to a second device, at least one MPDU of a plurality of MPDUs within the data frame via a data channel, and receive feedback corresponding to the at least one MPDU in a feedback channel while at least a first MPDU of the remaining MPDUs within the data frame is being transmitted. In another aspect, a first device, e.g., receiver of data frame, may receive, from a second device, at least one MPDU of a plurality of MPDUs within a data frame, and transmit feedback corresponding to the at least one MPDU while at least a first MPDU of the remaining MPDUs within the data frame is being received.

Abstract: Example methods, apparatuses, and computer-readable mediums for wireless communication are provided. In one example, a first device may be configured to determine whether to allow unscheduled access to the first device by a second device. The first device may be configured to transmit, based on the determination, first information to the second device. The first information may include a first indication indicative of whether the second device is allowed to transmit to the first device outside of a scheduled access period, or a second indication indicative of whether the second device is allowed to transmit to the first device without first receiving a trigger.

Abstract: Methods and apparatuses are provided that include counting devices for broadcast data services. The devices can be counted based on registrations received from the devices. This registration count can additionally or alternatively be used to determine whether further counting is desired. In addition, base stations can transmit counting requests to the devices using a paging message or other message such that idle mode devices can receive the counting requests. The idle mode devices can respond to the requests or send autonomous counting report by switching to an active mode for the purpose of responding or another purpose.
