    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: A wireless device is configured to switch data rates to account for temporary channel conditions or device configuration errors. Pre-selected data rates, more likely to achieve maximum goodput, are stored in a data rate table. The data rate table contains candidate data rates for each pre-selected data rate in the data rate table. When probe transmissions using the preselected data rates fail, dynamic rate probing is utilized to determine a possible cause and extent of the problem. The dynamic rate probing scheme transmits probe transmissions using the candidate data rates and tracks success or failure of these probe transmissions. An analysis of the probe transmissions is used to indicate a possible cause and/or extent of the problematic condition and to determine whether there is a need to reconfigure the data rates in the data rate table.

    Abstract: Systems and methods are disclosed for coordinating operation on multiple frequency bands between two or more multiple concurrent band (MCB) devices. The band switch protocols may include sending information on a second band after a communications link has been established on a first band. The receiving device may treat the transmission of the frame on the new band as a message to switch bands, such that the transmitting and receiving devices may conduct subsequent communications on the new band. Further, the band switch protocols allow for seamless operation over the band switch event. As a result, a frequency band having desired performance characteristics may be selected dynamically.

    Abstract: Beacon-poll frames are transmitted from a station (STA) to a wireless AP in an opportunistic manner. In response to receiving a beacon-poll frame, the wireless AP transmits a unicast beacon frame to the STA, thereby eliminating the need for the STA to periodically wake up to receive broadcast beacon frames from the AP. The wireless AP may transmit the unicast beacon frame at a higher speed than a conventional broadcast beacon frame. As a result, the time that the STA must be awake to receive the unicast beacon frame is significantly less than the time that the STA must be awake to receive a conventional broadcast beacon frame, thereby resulting in significant power savings within the STA. The wireless AP may aggregate downlink (DL) data packets to be transmitted to the STA with the unicast beacon frame, resulting in further power savings within the STA.

    Abstract translation: 信标轮询帧以机会性的方式从站（STA）发送到无线AP。 响应于接收到信标轮询帧，无线AP向STA发送单播信标帧，从而不需要STA周期性地从AP接收广播信标帧。 无线AP可以以比常规广播信标帧更高的速度发送单播信标帧。 结果，STA必须醒来接收单播信标帧的时间明显小于STA必须唤醒以接收常规广播信标帧的时间，从而导致STA内的显着功率节省。 无线AP可以将要发送到STA的下行链路（DL）数据分组聚合到单播信标帧，导致STA内进一步的功率节省。

    Abstract: A method of providing aggregated MAC protocol data unit (AMPDU) duration control in a wireless communication device includes setting an AMPDU duration. Pass/fail statistics are collected for each MPDU of an AMPDU in a time window, W. A packet error rate (PER) difference is calculated between first and last sets of MPDUs for each AMPDU in the window. An average PER difference is calculated across all AMPDUs in the window. When the average PER difference is greater than a first threshold, then the AMPDU duration is decreased. When the difference is less than a second threshold, then the AMPDU duration is increased. When the difference is within the first and the second thresholds, then the method returns to the step of collecting for a next time window. The AMPDU duration can also be adjusted based on detected Doppler and line-of-sight transmissions.

    Abstract translation: 在无线通信设备中提供聚合MAC协议数据单元（AMPDU）持续时间控制的方法包括设置AMPDU持续时间。 在时间窗口W中收集AMPDU的每个MPDU的通过/失败统计信息。在窗口中的每个AMPDU的第一组和最后一组MPDU之间计算分组错误率（PER）差异。 在窗口中的所有AMPDU之间计算平均PER差异。 当平均PER差大于第一阈值时，AMPDU持续时间减小。 当差值小于第二阈值时，AMPDU持续时间增加。 当差异在第一和第二阈值内时，该方法返回到下一个时间窗口的收集步骤。 AMPDU持续时间也可以根据检测到的多普勒和视线传输进行调整。
