Abstract: This disclosure includes systems and methods for determining the location of each of a plurality of STAs of a WLAN where an AP measures the round-trip time (RTT) and the angle of arrival (AOA) to each STA from implicit packet exchange, such as data frame and ACK frame. The AP may then report the RTT and AOA measurements to each STA using a dedicated beacon information element (IE) which multicasts RTT and AOA measurements to the STAs. By employing an additional parameter, namely, angle of arrival AOA, a single AP may compute the two-dimensional location of each associated STA. Further, another beacon IE may multicast mapping of the AIDs to MAC addresses so that the associated STAs can understand such mapping for STAs in a network so that one STA may know the location of other STAs. Encryption may be employed to achieve privacy.

Abstract translation: 本公开包括用于确定WLAN的多个STA中的每一个的位置的系统和方法，其中AP从隐式分组交换测量到每个STA的往返时间（RTT）和到达角（AOA），例如 数据帧和ACK帧。 然后，AP可以使用将RTT和AOA测量多播到STA的专用信标信息元素（IE）向每个STA报告RTT和AOA测量。 通过采用附加参数，即到达角AOA，单个AP可以计算每个相关STA的二维位置。 此外，另一个信标IE可以将AID多播到MAC地址，使得相关联的STA可以理解网络中的STA的这种映射，使得一个STA可以知道其他STA的位置。 可以采用加密来实现隐私。

Abstract: A communication device receives at least a portion of a packet. Power is reduced to a subset of components of a communication device. The subset of components for which power is reduced is determined based, at least in part, on a length of the packet. The power is reduced for a time period based, at least in part, on the length of the packet.

Abstract: Methods, systems, devices, and apparatuses are described for wireless communications in which first type of traffic may be transmitted from a gateway access point (AP) directly to a station. Beacon signals transmitted to the station are transmitted as part of the first type of traffic. A second type of traffic may be transmitted from the gateway AP to the station via at least one relay AP. The first type of traffic may include low-throughput traffic and may be transmitted over a long-range radio link (e.g., 2 GHz band link or sub-1 GHz band link). The second type of traffic may include high-throughput traffic and may be transmitted over at least one short-range radio link (e.g., 5 GHz band link). The gateway AP may receive low-throughput traffic directly from the station and high-throughput traffic from the station via the at least one relay AP.

Abstract: Systems and methods for dynamically adapting channel access or transmission parameters based upon an identified channel access parameter or previously used transmission parameter are disclosed. In an aspect, an electronic device for communication over a wireless network is disclosed. The electronic device comprises a processor configured to generate a message that identifies one rule of a plurality of rules. Each of the plurality of rules defines a process for adapting a value of a communication parameter based on an identified channel access parameter. Also, each of the plurality of rules provides a particular quality of service and a particular priority for communication with the electronic device. The electronic device further comprises a transceiver configured to transmit the message to a station.

Abstract: A network coordinator can assign an association identifier (AID) and/or a group identifier (GID) to identify a client station to which a packet is to be transmitted and to enable the client station to determine whether to receive an incoming packet. The network coordinator can determine a base AID that is representative of the network coordinator and can assign at least one AID to client stations to minimize the probability of client stations associated with proximate network coordinators being assigned the same AIDs. The network coordinator can also assign at least one GID to a group of client stations to minimize the probability of groups of client stations associated with the proximate network coordinators being assigned the same GID. The client station can analyze indications of a received AID and/or received GID to determine whether to receive the packet or whether to switch to an inactive power state.

Abstract translation: 网络协调器可以分配关联标识符（AID）和/或组标识符（GID）来标识要向其发送分组的客户端站，并使客户端站能够确定是否接收输入分组。 网络协调器可以确定代表网络协调器的基本AID，并且可以向客户站分配至少一个AID以最小化与被分配相同AID的邻近网络协调器相关联的客户站的概率。 网络协调器还可以向一组客户端站分配至少一个GID，以最小化与正在分配相同GID的邻近网络协调器相关联的客户端站组的概率。 客户端站可以分析所接收的AID和/或接收到的GID的指示，以确定是接收分组还是切换到无效功率状态。
