Abstract: A method is provided for wirelessly transmitting from a transmitter to one or more receivers within a multi-user (MU) multiple-input and multiple-output (MIMO) communication system. A number of concurrent (spatial) streams are dynamically allocated in a MU-MIMO transmission to each of a plurality of served receivers to maximize total data transmitted on each transmission. Streams are allocated according to a corresponding transmission queue length for each receiver and the number of receive antennas used by each of the served receivers. A transmission timer is started upon sending the transmission. A random backoff counter is also started upon one of either: (a) expiration of the transmission timer or (b) receipt of data at a transmission queue. A new transmission is sent upon expiration of the random backoff counter if the transmission timer has expired. Otherwise, the random backoff counter is restarted one or more times until the transmission timer has expired.

Abstract: A method includes receiving, at a first wireless device from a second wireless device, a signal (SIG) unit including a first field. The method also includes determining whether the first field has a particular value that is indicative of a zero-length payload and decoding the SIG unit based at least in part on the determination.

Abstract: The deferral mechanism described herein may improve medium reuse in a wireless network with transmit power imbalances. For example, in one embodiment, an apparatus employing the deferral mechanism described herein may comprise a receiver to sense a data unit transmitted on a medium associated with the wireless network, wherein the data unit may comprise information indicating a transmit power associated therewith. Furthermore, the apparatus may comprise one or more processors to initiate a transmission on the medium associated with the wireless network if the apparatus is not an intended receiver of the sensed data unit, the transmit power associated with the data unit exceeds a transmit power associated with the apparatus, and a received power associated with the data unit does not equal or exceed a clear channel assessment threshold plus a difference between the transmit power associated with the data unit and the transmit power associated with the apparatus.

Abstract: Methods and apparatus are described which increase the probability and/or frequency that devices with comparatively faster clocks in a network than other devices in the network will transmit beacon signals are described. As a result, devices with faster clocks will tend to drive system synchronization to convergence faster than if all devices transmitted beacons at the same rate, thus facilitating more reliable maintenance of system synchronization since the devices with faster clocks will tend to transmit more frequently.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for transmitting, receiving, and acknowledging MAC protocol data units (MPDUs), allowing single bits in a Block Acknowledgment (BA) bitmap to acknowledge receipt of multiple MPDUs. As a result, a greater number of MPDUs may be acknowledged than if each bit acknowledged only a single MPDU. By reducing the overhead associated with a re-transmission bitmap, a greater number of MPDUs may be aggregated, thereby increasing overall throughput.

Abstract translation: 本公开的某些方面提供用于发送，接收和确认MAC协议数据单元（MPDU）的技术和装置，允许块确认（BA）位图中的单个比特确认多个MPDU的接收。 因此，如果每个位只确认一个MPDU，则可以确认更多数量的MPDU。 通过减少与重传位图相关联的开销，可以聚合更多数量的MPDU，从而增加总吞吐量。

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for using information in a Very High Throughput Signal B (VHT-SIG-B) field in the preamble of a null data packet (NDP). Retaining the VHT-SIG-B field in NDPs offers several advantages, such as maintaining a unified IEEE 802.11ac preamble structure, providing for 4 μs extra time to process beamforming feedback, and being able to use information in the VHT-SIG-B field to determine a level of interference in the NDP.

Abstract translation: 本公开的某些方面涉及在空数据分组（NDP）的前导码中的非常高吞吐量信号B（VHT-SIG-B）字段中使用信息的方法和装置。 保留NDP中的VHT-SIG-B字段提供了几个优点，例如保持统一的IEEE 802.11ac前导码结构，提供4μs的额外时间来处理波束成形反馈，并且能够使用VHT-SIG-B字段中的信息 以确定NDP中的干扰程度。
