Abstract: A method for neighbor scanning in a wireless local area network having a station, a first access point, AP, to which the station is associated, and a second AP, comprising the steps of generating timing information regarding a beacon signal sent by the second AP, reporting the timing information from the first AP to the station and scheduling at the station a time, based on the timing information, to listen for the beacon signal transmitted by the second AP. The timing information includes an indication of a time difference between a second beacon signal sent by the access point and the first beacon signal sent by the second AP and the time difference is an offset in timing units.

Abstract: A method and apparatus for use by a first transceiver, (e.g., wireless transmit/receive unit (WTRU), access point (AP), node) for adjusting the transmission rate of packets transmitted to a second transceiver based on signals the first transceiver receives from the second transceiver. In one embodiment, a transmission packet error rate (Tx PER) process is used to adjust the packet transmission rate. In another embodiment, a relative signal strength indicator (RSSI)-based process is used to determine the RSSI of packets received at the first transceiver from the second transceiver for adjusting the packet transmission rate. In another embodiment, transmission quality indicators are measured at the second transceiver and are sent to the first transceiver, which derives a new packet transmission rate therefrom. The Tx PER and RSSI-based processes may be used individually, in combination, or in conjunction with other processes.

Abstract: A multi-node communication system and method used to request, report and collect destination-node-based measurements and route-based measurements is disclosed. The communication system may be a mesh network including a plurality of mesh points (MPs). In one embodiment, a destination-node-based measurement request is sent to one or more destination nodes via destination-unicast, destination-multicast, or destination-broadcast, using routes specified via next-hop-unicast, next-hop-multicast, or next-hop-broadcast addressing. In another embodiment, a source node sends a measurement request message to a final destination node, whereby each node along the route individually sends a measurement report message to the source node. Alternatively, measurement results of each node are combined and appended to the measurement request message, and a measurement report message including the combined measurement results is sent to the source node.

Abstract: A wireless communication method and system for optimizing channel selection for an AP. The channel selection optimization process includes four sub-processes: 1) a measurement process; 2) a candidate channel determining process; 3) a channel selection process; and 4) a channel update process. Candidate channels used for supporting communication performed by the AP are determined. The candidate channels are chosen from an allowable channel set (ACS) if a detected interference of each candidate channel is less than an established maximum allowed interference.

Abstract: A method for seamless channel change in a wireless local area network having a station STA (204) and an access point AP (202) begins with sending a channel change intention message from the AP to STA (210). A channel change response message (212) is sent from STA to the AP, informing the AP whether the STA will follow the channel change. The AP determines whether to proceed with the channel change, and performs the change if the determination is positive.

Abstract: A method for radio resource management (RRM) in a wireless local area network (WLAN) having an access point and a station begins by obtaining a first group of parameters from a current traffic channel. Measurements from all available channels are taken for a second group of parameters. The radio resources of the WLAN are autonomously managed by selectively invoking at least one RRM algorithm that uses at least one parameter. A RRM algorithm may be invoked based upon results produced by a previously executed RRM algorithm, whereby RRM algorithms may be continuously invoked such that the radio resources are autonomously managed.

Abstract: A method and communication system (e.g., TDD system) that uses adaptive antennas at the base stations to monitor metrics associated with the quality of one or more CPCH timeslots, so as to determine whether to reuse some or all of the CPCH timeslots to transmit the DPCH. If it is determined to reuse some or all of the CPCH timeslots, an additional determination is made as to what limit to apply on the DPCH transmission powers. Adaptive antennas may be used at the base stations to allow the system to reuse some or all of the CPCH timeslots to transmit DPCH, thus improving the overall capacity of the system while maintaining the CPCH coverage and quality at a desired level throughout the system.
