摘要： 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 begins by generating timing information regarding a beacon signal sent by the second AP. The timing information is reported from the first AP to the station. The station schedules a time, based on the timing information, to listen for the beacon signal transmitted by the second AP.

摘要： 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.

摘要： When a wireless transmit receive unit (WTRU) is using a reduced dedicated physical control channel (DPCCH) frame, the WTRU may periodically send a normal DPCCH frame. The WTRU may periodically increase the transmit power or send a normal DPCCH frame if there is a transmit power control (TPC) error or a downlink quality is below a threshold. When the WTRU implements DPCCH transmission gating, the WTRU may set a gating period based on the number of received TPC commands. The WTRU or Node-B may restore to a normal mode, if the link quality is below a threshold. The WTRU may periodically increase a transmit power. When a reduced signal-to-interference ratio (SIR) target is used for TPC, the WTRU may increase a transmit power, if the downlink power is not responsive. The WTRU or the Node-B may restore a normal SIR target if the link quality is below a threshold.

摘要： A method for accelerating discovery of access points (APs) in a wireless local area network begins by transmitting an advertisement packet by an AP via at least one channel other than a channel on which the AP transmits beacon signals. The advertisement packet is received by a station (STA), which then determines whether to associate to the transmitting AP. The advertisement packet can include reassociation information, such that the STA can associate to the AP based on the information in the advertisement packet, or timing information, such that the STA can tune to the AP and receive the AP's beacon without dwelling on the AP for an extended period of time.

摘要： In a wireless local area network having an access point (AP) and at least one station, wherein data is prioritized by access categories, a method for admission control begins by calculating a transmission budget for each access category (AC) and a total transmission budget for all Acs requiring admission control. A traffic stream admission request is sent from a station to the AP. A medium time value for the traffic stream is calculated at the AP, based on information extracted from the admission request. The medium time value is compared to the transmission budget for the AC corresponding to the traffic stream and the total transmission budget. The traffic stream is accepted if the medium time value is not greater than both the transmission budget for the AC corresponding to the traffic stream and the total transmission budget; otherwise, the traffic stream is rejected.

摘要： A method for handover a mobile unit from a first base station to a second base station in a wireless communication systems employing smart antenna technology. Following trigger events of a handover, the mobile station generates a physical signal sounding pulse transmitted by an isotropic antenna. The sounding pulse may consist of a common sequence of symbols or a specific sequence of symbols that uniquely identifies the mobile station. A series of sounding pulses can be sent according to a power ramping procedure until a base station has focused a communications beam toward the mobile. Receiving base stations provide feedback information upon detection of the sounding pulse allowing the mobile unit and/or base station to form communication beams toward each other. A mapping protocol may also be utilized by the communication system.

摘要： A method for admission control of control [plane] channel signaling requests includes receiving a signaling request (12). Upon receipt of signaling connection request, a first determination is performed to determine to provide admission (14), to common resources. When the first determination is negative, a second determination is performed to determine whether admission to dedicated resources (15). When the second determination is negative, the signaling request is rejected (21). When the second determination is positive, the request is admitted to dedicated resources (22). When the first determination is positive, a third determination is performed to determine whether the quality of signaling request is high or low (16). If the quality of the request is high, the signaling request is admitted to common resources (20). When the quality is low, a fourth determination is performed (18) to determine whether to provide admission to dedicated resources (22). If the fourth determination is [positive] negative , the request is admitted to common resources (20).

摘要： This invention relates to wireless local area networks, and particularly to the IEEE 802.11 family of standards. It consists of a method and apparatus that can be implemented in access points (APs) and subscriber wireless transmit/receive units (WTRUs), in order to allow an AP to initiate re-association of a WTRU to itself or a different AP. The invention improves the robustness of the network by enabling more efficient load balancing, congestion control, and roaming, without compromising the user experience.
