摘要： Beacons may be grouped to facilitate neighbor discovery in a wireless network. For example, neighboring access devices such as IEEE 802.11 access points may cooperate to transmit beacons in a group. In this way, a wireless device seeking to discover the neighboring access devices may scan for the beacons for a shorter period of time. An indication may be provided to enable a wireless device to more efficiently scan the beacons. For example, the indication may indicate the channel the wireless device should scan to receive the next beacon that is to be transmitted. In addition, the indication may include information relating to the transmission time of the next beacon.

摘要： Techniques for selecting rates for data transmission on eigenmodes of a MIMO channel are described. An access point transmits an unsteered MIMO pilot via the downlink. A user terminal estimates the downlink channel quality based on the downlink unsteered MIMO pilot and transmits an unsteered MIMO pilot and feedback information via the uplink. The feedback information is indicative of the downlink channel quality. The access point estimates the uplink channel quality and obtains a channel response matrix based on the uplink unsteered MIMO pilot, decomposes the channel response matrix to obtain eigenvectors and channel gains for the eigenmodes of the downlink, and selects rates for the eigenmodes based on the estimated uplink channel quality, the channel gains for the eigenmodes, and the feedback information. The access point processes data based on the selected rates and transmits steered data and a steered MIMO pilot on the eigenmodes with the eigenvectors.

摘要： Techniques for controlling transmissions in wireless communication networks are described. In one aspect, transmission control for a mesh network may be achieved by ranking mesh points or stations in the mesh network. In one design, the rank of a first station in the mesh network may be determined. At least one station of lower rank than the first station in the mesh network may be identified. At least one transmission parameter for the at least one station of lower rank may be set by the first station. In another aspect, stations may be assigned different transmission parameter values to achieve the data requirements of each station. At least one transmission parameter value may be selected for each station based on the rank, QoS requirements, amount of traffic, and/or achievable data rate for that station and may be sent (e.g., via a probe response message) to the station.

摘要： To select a transmission mode to use for a data transmission via a MIMO channel from station A to station B, station A obtains channel information used for spatial processing and determines the age of this information. Station A selects one of multiple transmission modes based on the age of the channel information and possibly other information (e.g., the fading characteristic of the MIMO channel). To select rate(s) to use for the data transmission, station A obtains channel state information (CSI) indicative of the received signal quality for the MIMO channel, e.g., received SNRs or "initial" rates. Station A determines the age of the CSI and selects one or more "final" rates based on the CSI, the age of the CSI, the selected transmission mode, and possibly other information. Station A processes data in accordance with the selected transmission mode and final rate(s) and transmits the processed data to station B.

Both aspects involve having a node stop processing a data packet that is not destined for it so as to be able to reserve its resources to detect control and other packets. An apparatus for implementing the techniques are also disclosed.

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling a traffic stream between mesh points in a mesh network. SOLUTION: Data arriving from the mesh point are aggregated in packet queues (814). The packet queues segregate arriving data by the Quality of Service (QoS) requirement of the data. An appropriate communication channel is selected. The communication channel is accessed through a contention access schema (808). An M-Request-To-Send (MRTS) message is sent to a potential receiving mesh point, and a receiving mesh point responds with an M-Clear-to-Send (MCTS) message (812). Data from the packet queues are transmitted to the next mesh point (814). A mesh point power save mode makes a battery-operated mesh point sleep, thus preserving power. COPYRIGHT: (C)2011,JPO&INPIT
