Abstract: Transmission power levels of uplink/downlink communication is controlled in a wireless communication system. A receiving station produces and provides to a transmitting station power control information based upon received signals from the transmitting station. A measured block error rate (BLERmsr) is obtained from the number of erroneous blocks in a sliding window of the last N received data blocks and SIR adjustments are set based upon the BLERmsr and a target BLER (BLERtarget). A target SIR of received signals is adjusted according to the SIR adjustments.

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 changing a channel in a wireless local area network (WLAN) to alleviate congestion and high interference levels, the WLAN having an access point (AP) and at least one station, begins by determining a list of candidate channels. A channel is selected from the candidate list and is evaluated against predetermined criteria. If the selected channel meets the predetermined criteria, then all of the stations communicating with the AP are disassociated and the AP is changed to the selected channel. If the selected channel does not meet the predetermined criteria, then the selected channel is removed from the candidate list and the selecting step is repeated if there are additional candidate channels.

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 wireless communication method and apparatus for controlling the power of signals (105) transmitted by downlink (DL) and/or uplink (UL) coded composite transport channels (CCTrCHs). A base station (110) transmits signals to a wireless transmit/receive unit (WTRU) (115) via at least one UL CCTrCH. The base station (110) determines whether or not discontinuous transmission (DTX) of a UL CCTrCH that controls the power of a DL CCTrCH is employed, and/or the WTRU determines whether or not DTX of a DL CCTrCH that controls the power of a UL CCTrCH is employed. The power of the CCTrCHs is incremented or decremented by a first step size when DTX is employed, and by a second step size when DTX is not employed.

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 for determining whether a connection event between a base station and a wireless transmit/receive unit (WTRU) should be accepted or rejected, comprises measuring the interference level I0 in a candidate timeslot; measuring the path loss L between the base station and the WTRU; measuring the total transmit power P0 of the base station; determining a thermal noise level &thetas;; determining a fading average signal-to-interference ratio (SIR); and calculating a ratio R, wherein if the ratio R is above a certain threshold the connection event will be accepted and if the call is below the threshold it will be rejected.

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.

Abstract: The present invention establishes a system on how to best use adaptive antennas at a base stations and optionally at wireless transmit receive units (WTRUs) to mitigate the interference due to conflicting slot assignments between two neighboring cells. This system will allow for a greater flexibility in slot-to-cell assignments, especially when conflicting slot assignments are for two cells or mobiles in the same vicinity, more specifically, one cell uses a slot assignment for an uplink while the other cell uses the same slot assignment for downlink.
