摘要： In a method of determining an available channel bandwidth in a communication system, wherein the communication system utilizes i) a set of component channels for transmitting data streams and ii) a set of access control channels, and wherein each of at least some of the access control channels partially overlaps, in frequency, at least one of the component channels, whether a primary channel of the access control channels is idle is determined. The primary channel partially overlaps, in frequency, at least a first one of the component channels. That a composite channel includes one or more of the component channels is determined based at least on a determination of whether the primary channel is idle. A signal is caused to be transmitted via the composite channel after determining that the composite channel includes one or more of the component channels.

摘要： A method in a communication network includes an access point, using a multiple input multiple output antenna configuration, sending out a sounding packet to a plurality of client stations. The client stations determine a channel estimation of the sounding packet, but only a channel estimation of a portion of the entire sounding packet to avoid processing the entire packet. The resulting partial estimation is sent to the access point for using in transmit beamforming. In other examples, the client station sends a reverse link sounding packet over a portion a channel having a bandwidth less than the sounding packet, and from this the access point determines partial channel estimations and transmit beamforming conditions.
