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: A wireless device (e.g., a station (STA)) may receive a transmission soliciting a control transmission (e.g., a soliciting transmission). The STA may identify a transmission parameter indicator, which may indicate a change in one or more parameters in a control response transmission parameter set (e.g., a set of parameters used for control transmissions in response to the soliciting transmission). The STA may transmit the control transmission in response to the soliciting transmission based on the identified transmission parameter indicator. The control response transmission parameter set may include a frame format, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) format, a bandwidth, a modulation scheme, an encoding scheme, a modulation and coding scheme (MCS), a number of spatial streams (NSS), and/or a PPDU duration. In some cases, the transmission parameter indicator may indicate disabling or resumption of extended range (ER) single user (SU) PPDU format usage.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for using a shortened block acknowledgement (BlockAck) frame capable of acknowledging fragments. Such a shortened BlockAck frame may include a bitmap field having a shorter length than that of a basic BlockAck frame in the IEEE 802.11 standard (i.e., <128 octets). One example method for wireless communications generally includes receiving a plurality of protocol data units (PDUs) (e.g., media access control (MAC) protocol data units (MPDUs)); determining whether each of the PDUs was successfully received and whether each of the PDUs is associated with a non-fragmented service data unit (SDU) (e.g., MAC service data unit (MSDU)) or a fragmented SDU; and outputting for transmission a shortened BlockAck frame comprising a bitmap field indicating a receive status for the non-fragmented and fragmented SDUs based on the determination.

Abstract: A method for wireless communication may include receiving a communication and determining an acknowledgement signature for an acknowledgment in response to the communication. The acknowledgment signature may allow for authentication with the transmitting wireless device. The acknowledgment signature may be based on a key shared with the wireless device. An acknowledgement frame (e.g., acknowledging reception of the communication) may then be sent to the transmitting wireless device. The content of the acknowledgement may be based on the acknowledgement signature. For example, the signature may be included in a frame control, duration, or address field. Determining the acknowledgement signature may include determining a unique signature based on information from the received communication (e.g., a cyclic redundancy check (CRC)), the shared key, and/or a hash function.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may win access to an unlicensed frequency channel for a transmission opportunity. For the transmission opportunity, the AP may dynamically schedule a duration of time to be used for uplink transmissions and a duration of time to be used for downlink transmissions. The schedule may be based on a comparison of values for a parameter monitored by the AP. The parameter may be monitored for uplink traffic and for downlink traffic. The parameter may indicate the latency experienced by each direction of traffic, or an intolerance of each direction of traffic to delay. The AP may schedule the uplink and downlink durations to compensate for the discrepancy in latency between the two directions of traffic.

Abstract: Disclosed herein are techniques for range measurement between one or more wireless stations (STAs) and a first access point (AP). In various embodiments, the first AP may synchronize a clock of the first AP with clocks of one or more synchronized APs. The first AP may perform a synchronization session with the one or more STAs. The first AP may also transmit one or more Broadcast time-of-departure (TOD) frames to the one or more STAs. Each of the one or more Broadcast TOD frames may include a time of departure of a Broadcast TOD frame from the first AP. A second AP and a third AP of the one or more synchronized APs may also transmit one or more Broadcast TOD frames to the one or more STAs for range and/or position determination.

Abstract: System and method for improving channel efficiency in a wireless link between an access-point transceiver and a first transceiver. The first transceiver may have a first data throughput rate that is lower than the maximum possible data throughput rate of the wireless link. The first transceiver may include a first receive buffer. An indication of the first data throughput rate and a size of the first receive buffer may be received and stored by the access-point transceiver. A first size of a first data packet for transmission to the first transceiver may be determined by the access-point transceiver based on one or more of the first data throughput rate and/or the size of the first receive buffer. The first data packet of the first size may be transmitted to the first transceiver by the access-point transceiver at a data rate that is higher than the first data throughput rate.
