    摘要： Certain aspects of the present disclosure generally relate to apparatus and methods for switching operating bandwidth and/or operating channel in a wireless communications network. A transmitting STA may send an announcement of a switch to a particular bandwidth in a frame, wherein the presence of absence of a Secondary Channel Offset Element and a Wide Bandwidth Channel Switch Element in the frame indicates whether the particular bandwidth belongs to a first or second set of operating bandwidths. The presence of the Secondary Channel Offset Element and a Wide Bandwidth Channel Switch Element in the frame may indicate a switch to the first set of operating bandwidths. The first set of operating bandwidths may include VHT channels including 80 MHz only, 80+80 MHz and 160 MHz channels. The absence of the Secondary Channel Offset Element and a Wide Bandwidth Channel Switch Element in the frame may indicate a switch to the second set of operating bandwidths. The second set of operating bandwidths may include 20 MHz and 40 MHz channels.

    摘要： A method for transmitting information in a wireless system is provided. In this method, the traffic on a plurality of channels can be determined. A bandwidth for a packet can be selected based on the traffic and available channel bandwidths. A modulation and a coding rate can be selected from a plurality of modulations and associated coding rates. The modulation and coding rate can be applied to a segment of the packet, wherein each segment includes one or more bandwidth units. The packet including the selected modulation and coding rate therein can be transmitted on at least one channel.

    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： The position of a target wireless device in a wireless communication network can be calculated relative to a predetermined number of reference wireless devices in the wireless communication network to preclude the need for fixed/absolute reference points. The reference wireless devices can be selected based, at least in part, on comparing one or more performance measurements associated with each wireless device against one or more corresponding threshold performance measurements. The position of each of the reference wireless network devices relative to each other is determined based, at least in part, on a distance between each pair of the reference wireless network devices. The relative position of the target wireless network device is determined based, at least in part, on the position of each of the reference wireless network devices relative to each other and a distance between the target wireless network device and each of the reference wireless network devices.
