摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：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。

摘要： Certain aspects of the present disclosure generally apply to a wireless local area network (WLAN) where an access point (AP) has data to send to multiple stations (STAs). By using the Downlink Spatial Division Multiple Access (DL-SDMA) technique, the AP may send data at the same time towards multiple STAs. Certain aspects of the present disclosure provide techniques and apparatuses for detecting that a multiuser multiple-input multiple-output (MU-MIMO) transmission has suffered a collision and to adapting a contention window (CW) size for a backoff counter applied to a subsequent MU-MIMO transmission.

摘要： Methods and apparatus for network setup in wide channel WLANs are provided. Techniques for co-existence of 20 MHz and 40 MHz networks (e.g., as defined by IEEE 802.11n) may be extended to 80 MHz and 160 MHz networks. For example, a primary channel of an existing network may be designated as the primary channel of a new network. Further, a primary channel of the existing network may not be used as a secondary channel in the new network. Intolerance operation between networks may include a first network releasing one or more channels in response to an intolerance indication received from a second network. Furthermore, in response to the intolerance indication from the second network, the first network may utilize one or more channels for communicating in the first network using a first set of access parameters. The access parameters may depend on the intolerance indication.
