    Abstract: Methods, systems, and devices are described for adapting blind reception duration for range and congestion. A wireless station may measure channel conditions (e.g., range to an access point (AP) and channel congestion), and adjust one or more sleep timers based on the conditions. The sleep timers may each be associated with a window for reception of an expected transmission. If the transmission is not received in the window, the station may enter a sleep state to conserve power. In one example, a beacon miss timer is adjusted, and the expected wireless transmission is a delivery traffic indication message (DTIM). In another example, a content after beacon (CAB) timer is adjusted and the expected wireless transmission is the CAB. In some cases, the station may measure a delay for a number of beacons and determine the adjustment based on the delays.

    Abstract translation: 描述了用于适应范围和拥塞的盲接收持续时间的方法，系统和设备。 无线站可以测量信道条件（例如，到接入点（AP）的范围和信道拥塞），并且基于条件来调整一个或多个睡眠定时器。 睡眠定时器可以各自与用于接收预期传输的窗口相关联。 如果窗口中没有接收到传输，则站可能进入睡眠状态以节省电力。 在一个示例中，调整信标缺失定时器，并且期望的无线传输是传送业务指示消息（DTIM）。 在另一示例中，调整了信标（CAB）定时器之后的内容，并且预期的无线传输是CAB。 在某些情况下，车站可以测量多个信标的延迟，并根据延迟确定调整。

    Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system through efficient transmissions and acknowledgements of information between an AP and a station. The time between a determination by a station to enter a power saving mode and entering network sleep mode by the station may be reduced through a transmission, by an AP, of an MPDU to the station successive to an SIFS after transmission of an acknowledgement to the station of a PS-Poll frame from the station. The time to enter a power saving mode by a station may also be reduced through transmission of A-MPDUs in which a last MPDU of the A-MPDU has an indicator bit cleared to indicate no additional data is to be transmitted. An AP may prevent a retransmission of an MPDU to the station in the absence of an acknowledgement from the station, to further enhance efficiency.

    Abstract translation: 描述了无线通信系统中的功率节省的方法，系统和设备，通过AP和站之间的有效传输和信息确认。 在站点确定进入节电模式并进入网络睡眠模式之间的时间可以通过AP向MPI发送确认之后的MPDU向连续的SIFS的站传输而减少 站点的PS-Poll帧。 由站点进入省电模式的时间也可以通过A-MPDU的传输来减少，其中A-MPDU的最后一个MPDU被清除以指示不发送附加数据。 在没有来自站的确认的情况下，AP可以阻止对站的MPDU的重传，以进一步提高效率。

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for low latency multicast wireless communication. In one aspect, multicast wireless communication may be used in a wireless local area network (WLAN) to distribute audio or video information from an access point to multiple stations. To maintain reliability and low latency, techniques of this disclosure include link training, link adaptation, and blind retries using different transmission rates. In some implementations, a station that detects a link deterioration (such as a loss of data or change in channel quality) can send an unsolicited action frame to the access point. Using the techniques in this disclosure, the access point and the station(s) may maintain the reliability of the multicast wireless communication.

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for wireless coexistence. In one aspect, an electronic device may have a first wireless interface associated with a first wireless communication technology (such as a wireless local area network, WLAN, technology). The first wireless interface may use measurements of raw energy detected on a wireless channel to determine that a second wireless communication technology (such as a wide area network, WAN, technology) is being used on the wireless channel by another device. In one aspect, the electronic device does not need to decode the coexisting communication signals to determine time alignment for the second wireless communication technology. The electronic device may modify a transmission schedule for the first wireless communication technology based on the coexisting second wireless communication technology.
