摘要： This disclosure describes techniques for operating a client device to communicate with a wireless access point to validate data within a frame by comparing channel quality metrics and duration metrics to thresholds. Information received within a validity window may be treated as correctly received even if the frame fails a subsequent verification process or if reception of the frame is terminated prior to the end of the frame.

摘要： Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network. includes creating a shortened network identifier having a first length from a full network identifier having a second length. The first length is shorter than the second length. The method further includes generating a compressed beacon including the shortened network identifier. The method further includes transmitting, at an access point, the compressed beacon.

摘要： Circuits, methods, and apparatus that reduce overhead and channel bandwidth required for data reception acknowledgment. One such system uses an enhanced block acknowledgment that acknowledges frames received for different data streams. Another system sends an acknowledgment after the occurrence of a triggering event, such as the end of a duration, the reception of a number of frames, or the reception of a frame having a specific sequence number. Another removes the need for acknowledgment frames by including an acknowledgment field in a transmitted data frame. These block acknowledgments and acknowledgment fields may include an acknowledgement of frames received for each data stream having different traffic identifications, they may be for all received frames or for a specific class or groups of classes of traffic, for specific user priorities, or for other subgroups of received frames, and more that one acknowledgment may be included.

摘要： Methods, systems, and devices are described that enable a WLAN access point (AP) to schedule packet transmissions to (or from) a mobile device taking into consideration the schedule of various other coexisting transmission/reception (Tx/Rx) activities on the mobile device. Various approaches may increase throughput at the mobile device. Various approaches also may benefit other stations associated with the same AP.

摘要翻译： 通过AP和站之间的有效传输和确认信息来描述无线通信系统中的功率节省方法，系统和设备。 由站点确定进入省电模式和进入网络休眠模式之间的时间可以通过由AP发送到SIFS之后的站点的MPDU在发送确认到 来自电台的PS-Poll帧的电台。 站点进入省电模式的时间也可以通过发送A-MPDU来减少，其中A-MPDU的最后MPDU具有清除的指示符比特以指示不需要发送附加数据。 在没有来自站的确认的情况下，AP可以防止MPDU向站重传，以进一步提高效率。
