    Abstract: A method of performing transmission from an access point (AP) in a wireless communication system provides transmission setting adjustment after sounding. In this method, stations associated with the AP and having transmission data can be identified. Transmission to those stations can be performed using a predetermined transmission setting. For a first transmission after a sounding, the predetermined transmission setting can be boosted. For any transmission other than the first transmission after the sounding, a current or adjusted transmission setting can be used based on a detected PER during transmission. An adjusted transmission setting can be an MCS rate, a user-level (SU-BF, 2U-MIMO, or 3U-MIMO), or an aggregated MAC protocol data unit (AMPDU) aggregation level. A single transmission setting or a combination of settings can be used. The method can be used with any transmission setting(s), including those mapped from the Signal to Interference and Noise Ratio (SINR).

    Abstract: An access point determines the buffered data for each station of a plurality of stations in a BSS and groups the stations with similar station characteristics. The transmission time to the stations in a group can be apportioned. The groups can be ordered based on station characteristics and a transmission history. A sounding for a group can be performed based on the order. The MU-MIMO transmission for the group can be performed until a first condition is met. If the first condition is met, then the sounding and the MU-MIMO transmission for a next group can be performed, according to the order, until a second condition is met. The first condition can include an apportioned transmission time having expired and/or the buffers for the group being flushed. The second condition can include new data having been buffered by the AP and/or all buffered data having been transmitted.

    Abstract: Methods, systems, and devices are described for wireless communication. An access point (AP) may determine a single user bias for a wireless device based on a feedback signal-to-noise ratio (SNR) and an SNR based on a modulation and coding scheme (MCS). The AP may also determine a multi-user SNR for the wireless device based on the feedback SNR, the single user bias, a multi user loss, and a group bias. The AP may then select an updated MCS based on the multi-user SNR. In some cases, the AP may transmit a reference signal to the wireless device and receive a compressed beamforming feedback report from the wireless device based on the reference signal. The feedback SNR may be based on the compressed beamforming feedback report. The AP may also maintain a blacklist of groups with channel correlation that satisfies a threshold, and refrain from scheduling those groups together.

    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).

    Abstract: Systems and methods are disclosed for scheduling SU and MU traffic in a MIMO communications system. Net goodput may be estimated for a station using a plurality of MIMO modes and a transmission to the station may be scheduled using one of the MIMO modes based, at least in part, on the estimated net goodput. Estimating net goodput may include determining a number of bits that may be successfully transmitted to the station using the MIMO mode divided by a time required to transmit the number of bits plus the sounding time. Further, the number of bits that may be successfully transmitted to the station may be based on the number of packets that may be delivered over the upcoming sounding interval and statistically determined goodput for each MIMO mode.

    Abstract: A method of performing MIMO wireless communication includes identifying a first wireless device that qualifies for inclusion in a multi-user (MU) group and identifying a set of one or more candidate wireless devices, distinct from the first wireless device, that qualify for inclusion in the MU group. The set includes a second wireless device. A determination is made that an estimated MU-mode net goodput for the first and second wireless devices is greater than an estimated average single-user-mode net goodput for the first and second wireless devices. The first and second wireless devices are included in the MU group based at least in part on the determination. A transmission is sent to the MU group. Net goodput corresponds to a number of bits that may be successfully transmitted divided by a sum of a time to transmit the number of bits and a time associated with network overhead.
