Abstract: PROBLEM TO BE SOLVED: To allow an AP to initiate the re-association of a WTRU without loss of performance.SOLUTION: A transceiver of an access point (AP) according to the invention is configured to send a request message to a wireless transmit/receive unit (WTRU) using a first set of communication parameters and configured to receive a response message from the WTRU using the first set of communication parameters. The request message includes an identifier of a second AP, a second set of communication parameters, and a field that indicates whether disassociation of the WTRU from the AP is immediate. The response message indicates whether the WTRU accepts or rejects connection with the second AP.

Abstract: 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 (102) 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 (108), based on information extracted from the admission request (106). 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 (110); otherwise, the traffÊc stream is rejected (112).

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 apparatus for admission control and resource tracking in a wireless communication system (300) is disclosed. A wireless transmit/receive unit (WTRU) (305) and a base station (310) maintain parameters for admission control including parameters for the amount of time available for admission of traffic of each access category and for the amount of time available for admission of all access categories and parameters for admitted time and used time for the WTRU (305). Upon receipt of an admission request for a traffic stream from the WTRU(305), the base station (310) determines whether to accept or deny the request based on the medium time for the requested traffic stream and the available time for the access category and total available time. The base station tracks the actually transmitted time by the WTRU(305), reclaims the unused time (220) and returns the reclaimed time (240) to either a common pool or to the WTRU (305) as needed.

Abstract: An access point (14) operates in an 802.11 wireless communication network (10) communicating with a client station (12), and includes a smart antenna (16) for generating directional antenna beams (20) and an omni-directional antenna beam (22). An antenna steering algorithm (18) scans the directional antenna beams and the omni-directional antenna beam for receiving signals from the client station (12). The signals received via each scanned antenna beam are measured, and on of the antenna beams is selected based upon the measuring for communicating with the client station (12). The selected antenna beam is preferably a directional antenna beam. Once the directional antenna beam has been selected, there are several usage rules for exchanging data with the client station (12). The usage rules are directed to an active state of the access point (14), which includes a data transmission mode and a data reception mode.

Abstract: An improved method of network management, particularly in the context of standards IEEE802.11 and IEEE802.11k, through two new MAC measurements, with attendant advantages. The two new measurements include WTRU uplink traffic loading measurement, and an AP service loading measurement and is generally applicable at least to layers 1 and 2 as applied to a least 802.11k in the context of OFDM and CDMA 2000 systems, but is applicable to other scenarios as well. A Method for determining and advertising congestion is also provided for a Wireless Local Area Network (WLAN) system. The present invention also introduces a method for managing congestion when congestion is detected. This aspect of the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/ Collision Avoidance (CSMA/CA) mechanism. The methods are advantageously implemented in selectively configured WTRUs of various forms.

Abstract: A method for optimizing clear channel assessment (CCA) parameters in a wireless local area network having an access point (AP) and at least one station begins by receiving a trigger condition. An upper bound and a lower bound for an energy detect threshold (EDT) parameter are determined. A value of the EDT parameter is calculated and is bound by the upper bound and the lower bound. Lastly, the EDT parameter is updated. The method can be performed at each station or at the AP, with the updated CCA parameters being signaled to each station associated with the AP.
