    Abstract: An access point can include an array of antennas and a smart antenna selector. The smart antenna selector is configured to select a subset of antennas from the antenna array for use in multi-user multiple-input multiple-output (MU MIMO) data transmissions. Stations that are communicatively coupled to the access point can be selected for inclusion in a multi-user group based, at least in part, on performance measurements of the stations. Performance measurements are determined directly and indirectly from data transmissions sent in response to sounding packets. Antennas for use in MU MIMO data transmissions are selected for the antenna array based, at least in part, on previous antenna selections used for single user data transmissions.

    Abstract: A system and method are disclosed for performing ranging operations between two wireless devices without employing cyclic shift diversity (CSD) compensation techniques. For some embodiments, a first wireless device sends a negotiation request frame requesting the second wireless device to respond to subsequently received frames of a specified type using a selected one of the transmit chains in the second wireless device. Thereafter, the first wireless device sends a data frame to the second wireless device to initiate a ranging operation. The second wireless device sends a response frame of the specified type to the first wireless device using the selected one of the transmit chains.

    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may buffer uplink communications. However, such approaches may be improved. An access point (AP) may receive, from a station, uplink traffic of a traffic flow for forwarding to a backhaul network via a backhaul link. The AP may monitor a buffer of the AP to determine that a quantity of buffered uplink traffic received from the station exceeds a buffer quota, the buffer quota set for the traffic flow based on a traffic throughput capacity of the backhaul link and a throughput parameter for the traffic flow. The AP may modify, based on the quantity of buffered uplink traffic exceeding the buffer quota, an uplink communication scheme to reduce the quantity of uplink traffic from the station. The AP may communicate with the station based on the modified uplink communication scheme

    Abstract: Methods, systems, and devices are described for saving power in wireless communications. One aspect includes providing an indication of a sleep duration for transmission to a wireless node, communicating with the wireless node during a target wakeup time (TWT), wherein the communication comprises at least one of providing data for transmission to the wireless node or obtaining data received from the wireless node, and refraining from providing data for transmission to the wireless node for at least the indicated sleep duration based at least in part on timing of the communication. Another aspect includes receiving an indication of a sleep duration from a wireless node, communicating with the wireless node during a time slot of a TWT, and entering a sleep mode for the indicated sleep duration based at least in part on timing of the communication with the wireless node during the time slot of the TWT.

    Abstract: Methods, systems, and devices are described for wireless communication at a wireless device. A wireless device (e.g., station or access point) may adapt short inter-frame space (SIFS) burst parameters to improve the performance of the overall network while providing enriched user experience. A wireless device may monitor traffic conditions on the network and dynamically adapt the SIFS burst parameters associated with one or more stations based at least in part on detected variations on the traffic channel. In other examples, the wireless device may allocate a common SIFS burst parameter to be used by a plurality of wireless devices in the basic service set (BSS).
