    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 method for scheduling packets in a wireless local area network begins by mapping a packet to an access category (AC) based on a user priority of the packet (102). The packet is assigned to a traffic flow (TF) (104) in a station based on the AC of the packet. A packet from the TF is placed into a transmission queue (106) for the AC. A packet from the transmission queue is selected based on a quality of service-based contention resolution function (108), and the selected packet is transmitted (114).

    Abstract: A method and apparatus for alleviating congestion of a wireless medium used by an access point (AP) and a plurality of wireless transmit/receive units (WTRUs) is disclosed. If congestion is determined to exist on the wireless medium, a determination is then made as to whether there are any low priority traffic streams established between the AP and at least one of the WTRUs. If there are no low priority traffic streams established between the AP and at least one of the WTRUs, selected ones of the associated WTRUs are disassociated with the AP based on the amount of time spent by the WTRUs trying to transmit and retransmit unacknowledged packets or on a specific traffic stream access category. If low priority traffic streams have been established, the packet transmission delay associated with the low priority traffic streams is increased when congestion exists. Otherwise, the packet transmission delay is decreased.

    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: In a method for controlling channel access in wireless communications, an admitted time value is calculated for each access category in a station. The admitted time value is a maximum amount of medium time the station can use in a time period. A used time value is calculated for each access category in the station. The used time value is an amount of medium time used by the station. A determination is made whether the used time value is less than the admitted time value. If the used time value is less than the admitted time value, a frame with enhanced distributed channel access (EDCA) parameters is transmitted. If the used time value is not less than the admitted time value, a frame without the EDCA parameters is transmitted.
