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： 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 randomly generate 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 randomly 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.
摘要翻译：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。网络协调器可以随机生成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。网络协调器还可以随机地向一组客户端站分配至少一个GID，以最小化与被分配相同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。

摘要： System and method for improving channel efficiency in a wireless link between an access-point transceiver and a first transceiver. The first transceiver may have a first data throughput rate that is lower than the maximum possible data throughput rate of the wireless link. The first transceiver may include a first receive buffer. An indication of the first data throughput rate and a size of the first receive buffer may be received and stored by the access-point transceiver. A first size of a first data packet for transmission to the first transceiver may be determined by the access-point transceiver based on one or more of the first data throughput rate and/or the size of the first receive buffer. The first data packet of the first size may be transmitted to the first transceiver by the access-point transceiver at a data rate that is higher than the first data throughput rate.
