摘要： In a base station using spatial division multiple access communications, different length transmissions directed from a base station to different multiple mobile devices substantially simultaneously may have their start times adjusted so that the transmissions end at approximately the same time. The mobile devices may then respond during a response period with acknowledgments at approximately the same time. Thus all the acknowledgments may be received within the same time period from the end of the transmissions, reducing the likelihood of missed acknowledgments in responses to the shorter transmissions.

摘要： A wireless local area network (WLAN) includes an access point (AP), which provides communications channels to a plurality of stations. The AP supports spatial-division, multiple-access (SDMA) and accordingly includes a plurality of antenna subsystems. In order to achieve zero-forcing downlink beamforming, internal calibration procedures are occasionally performed within the AP. An internal calibration procedure includes an antenna subsystem transmitting a calibration signal. Received signals are measured at other antenna subsystems, and from these measurements, the transmit and receive chain gains are calculated for each antenna subsystem. One or more of these gains are adjusted to satisfy a primary condition, which is that the ratio of the transmit chain gain and the receive chain gain for all of the antenna subsystems are approximately equal (i.e., all of these ratios are equal to a calibration constant).
摘要翻译：无线局域网（WLAN）包括向多个站提供通信信道的接入点（AP）。 AP支持空分多址（SDMA），相应地包括多个天线子系统。为了实现迫零下行链路波束形成，AP内部偶尔执行内部校准过程。内部校准程序包括发送校准信号的天线子系统。在其他天线子系统中测量接收信号，并从这些测量中计算每个天线子系统的发射和接收链增益。调整这些增益中的一个或多个以满足主要条件，即，所有天线子系统的发射链增益和接收链增益的比率近似相等（即，所有这些比率都等于校准不变）。

摘要： A physical layer protocol data unit (PPDU) may include legacy preamble fields followed by a universal signal field (U-SIG). For an extended range (ER) transmission, the U-SIG is encoded to indicate via a bit whether the PPDU is an ER PPDU or a non-ER PPDU. When the U-SIG is encoded to indicate that the PPDU is an ER PPDU, the PPDU may include ER preamble fields following the U-SIG and an ER data field following the ER preamble fields. The ER preamble fields may comprise pre-ER modulated fields followed by ER modulated fields. The pre-ER modulate fields may comprise an ER short training field (ER-STF) followed by an ER long training field (ER-LTF) followed by an ER signal field (ER-SIG). The ER modulated fields may comprise at least the ER data field.
