Abstract: A method for communicating a list of handover candidates in a wireless local area network from a station to a serving access point (AP) begins by determining a list of handover candidate APs at the station. The candidate list is sorted at the station and is sent to the serving AP. The sending step can include sending the candidate list to the serving AP upon the expiration of a predetermined period of time or upon receipt at the station of an event trigger. The method can also include the step of requesting a candidate list from the station by the serving AP.

Abstract: A method for radio resource management (RRM) in a wireless local area networ k (WLAN) having an access point and a station begins by obtaining a first grou p of parameters from a current traffic channel. Measurements from all availabl e 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 wireless communication method and apparatus for optimizing the performance of an access point (AP) for reliably communicating with at least one wireles s transmit/receive unit (WTRU) in a wireless communication system. In one embodiment, the coverage area of an AP is autonomously determined. In anothe r embodiment the loads of an AP are balanced. In yet another embodiment, the transmission power level of an AP is determined and/or controlled.

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 startup process of an access point (AP) includes a discovery phase and an announcement phase. During the discovery phase, the AP detects neighboring APs from its own extended service set (ESS), neighboring APs from different ESSs, and external sources of interference. During the announcement phase, the AP transmits its beacon signals at maximum power in order to accelerate recognition by neighboring APs running the discovery phase. An automatic initialization channel selection process of an AP scans channels the AP will use to communicate. Information of each scanned channel is recorded and a best performance channel is determined for use by the AP.

Abstract: A method and system wherein timeslots designated in a wireless communication system as Common Physical Channel (CPCH) timeslots may be reused for user traffic. A CPCH timeslot used in a first cell (102) may be reused by a secon d cell (104), assuming the first and second cells transmit control information in different CPCH timeslots, for user traffic. The second cell is permitted to reuse the timeslot in which the first cell is transmitting control informati on so long as the second cell's reuse of that timeslot does not degrade recepti on of control information in the first cell.

Abstract: A method and communication system (e.g., a time-division duplex (TDD) system) that uses adaptive antennas at the base stations to monitor metrics associated with the quality of one or more common physical channel (CPCH) timeslots, so as to determine whether to reuse some or all of the CPCH timeslots to transmit a dedicated physical channel (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.

Abstract: A METHOD AND APPARATUS FOR SENDING A CHANNEL QUALITY INDICATION, CQI (206) VIA A SHARED CHANNEL WHILE A WIRELESS TRANSMIT/RECEIVE UNIT, WTRU (100) IS IN A CELL_FACH STATE WITHOUT HAVING A DEDICATED CHANNEL ALLOCATED FOR THE WTRU (100) ARE DISCLOSED. A WTRU (100) PERFORMS A MEASUREMENT OF AT LEAST ONE PARAMETER AND GENERATES A CQI (206) BASED ON THE MEASUREMENT. THE WTRU (100) THEN TRANSMITS THE CQI (206) VIA A RANDOM ACCESS CHANNEL, RACH. THE CQI (206) MAY BE TRANSMITTED USING AN RACH PREAMBLE. A PLURALITY OF SIGNATURE SEQUENCES MAY BE DIVIDED INTO A PLURALITY OF GROUPS. THE WTRU (100) MAY SELECT ONE GROUP BASED ON THE CQI (206) AND RANDOMLY SELECT A SIGNATURE SEQUENCE AMONG SIGNATURE SEQUENCES IN THE SELECTED GROUP FOR TRANSMITTING THE RACH PREAMBLE. THE CQI (206) MAY BE APPENDED TO THE RACH PREAMBLE. THE CQI (206) MAY BE TRANSMITTED VIA A CONTROL PART OR A DATA PART OF THE RACH MESSAGE. THE MOST ILLUSTRATIVE DRAWING:

Abstract: A method for taking measurements with a smart antenna in a wireless communication system having a plurality of STAs begins by sending a measurement request from a first STA to a second STA. At least two measurement packets are transmitted from the second STA to the first STA. Each measurement packet is received at the first STA using a different antenna beam. The first STA performs measurements on each measurement packet and selects an antenna beam direction based on the measurement results.
