摘要： A method and apparatus for efficiently processing packets from neighboring basic service sets (BSSs) to characterize the traffic within a wireless local area network (WLAN), mesh network, or similar wireless communication system is disclosed. The apparatus may be an access point (AP) in a BSS which includes a measurement period (MP) interval timer, a promiscuous measurement period (PMP) timer and a receiver filter. An interval of the MP interval timer is set while the receiver filter is enabled. During the interval, the AP only processes packets which originated from the AP's own BSS. When the MP interval timer expires, a value of the PMP timer is set to a predetermined time duration and the receiver filter is disabled. During the predetermined time duration, the AP processes all received packets irrespective of which BSS the packets originated from. The receiver filter is again enabled when the PMP timer expires.

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.
摘要翻译：一种用于加速在无线局域网中接入点（AP）的发现的方法，是通过除AP之外的信道以外的至少一个信道发送信标信号，由AP发送广告包开始的。广播包由站（STA）接收，该站然后确定是否与发送AP相关联。广告包可以包括重新关联信息，使得STA可以基于广告包中的信息或定时信息与AP相关联，使得STA可以调谐到AP并且接收AP的信标而不在AP上驻留一段较长的时间。

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： 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.

摘要： 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.

摘要： A silent measurement period (SMP) for a selected channel in an allowable channel set (ACS) of the access point (AP) is set. During the SMP, the AP does not serve wireless transmit/receive units (WTRUs) within its coverage area and reserves its channels for other BSSs. A normal operating channel of the AP is changed to the selected channel upon initialization of the SMP. Characteristics of the selected channel is measured during the SMP. The operating channel of the AP is changed back to the normal operating channel when the duration of the SMP expires.

摘要： 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.
