Abstract: A multi-node communication system and method used to request, report and collect destination-node-based measurements and route-based measurements is disclosed. The communication system may be a mesh network including a plurality of mesh points (MPs). In one embodiment, a destination-node-based measurement request is sent to one or more destination nodes via destination-unicast, destination-multicast, or destination-broadcast, using routes specified via next-hop-unicast, next-hop-multicast, or next-hop-broadcast addressing. In another embodiment, a source node sends a measurement request message to a final destination node, whereby each node along the route individually sends a measurement report message to the source node. Alternatively, measurement results of each node are combined and appended to the measurement request message, and a measurement report message including the combined measurement results is sent to the source node.

Abstract: In triggering a handoff by a wireless transmit/receive unit (WTRU) from a current basic service set (BSS) in a wireless local area network (WLAN), the following are performed. A highest class of traffic service and quality of service (QoS) is determined for the highest class from a basic service set (BSS) beacon. Handoff is terminated and communication is retained with a current BSS when the signal to noise ratio (SNR) or received signal strength (RSS) is greater than a high threshold of the highest class. Other criteria is evaluated to determine whether a handoff is desired when the SNR or RSS is less than the high threshold.

Abstract: A method for managing quality of service (QoS) in a wireless local area network begins by receiving a traffic flow (302). The traffic flow is mapped to a traffic class (TC), based on QoS requirements of the traffic flow (304). A transmission budget of an access class (AC) is calculated, each AC including at least one TC (306). A determination is made whether the traffic flow can be admitted, by calculating whether the transmission budget can support the traffic flow (308). If the traffic flow is admitted, the parameters of the TC are adjusted and collisions in the TC between existing traffic flows and the newly admitted traffic flow are managed (314).

Abstract: A method and apparatus for supporting data flow control in a wireless mesh network by reporting to a source mesh point (MP) in a particular path the allowed data rate that each MP in the path may support. The source MP sends, over the path, a data packet destined which includes a flow identification (ID) field and an available data rate field to a destination MP. An acknowledgement (ACK) packet including the same fields is sent in response to the data packet. The source MP adjusts a data rate in accordance with the available data rate field in the ACK packet. Alternatively, a congestion indication field may be used instead of the available data rate field to indicate that congestion exists on the path. Additionally, a quality of service (QoS) field indicating QoS parameters for the data flow may be included in the data and ACK packets.

Abstract: A temporary (temp) dedicated channel (DCH) is used to support communications. The temp-DCH channel is a channel that is assigned to a user having a set duration. After the duration expires, the channel is automatically released to the user. Embodiments of the invention relate to establishing the temp-DCH channel, determining the data rate and duration of the channel. Other embodiments relate to establishing back-to-back temp-DCH channels and the implementation details of these embodiments. Additionally, one embodiment relates to adding a start/stop function to the medium access controller which can be used in conjunction with temp-DCH as well as other applications.

Abstract: A method and system for managing radio resources in a time-slotted wireless communication system is based on the quality of service (QoS) information of a user. A plurality of time slots of a radio resource are sorted into a plurality of different categories, such as high QoS time slots, high capacity time slots, and balanced time slots (305). Each category is associated with a different level of QoS. QoS information with respect to a user is obtained in response to a radio resource request received from the user (310). The user is associated with a particular category of time slots based on the QoS information of the user (315).

Abstract: A method for congestion control in the uplink of a wireless communication system having a wireless transmit/receive unit (WTRU) and a radio network controller (RNC) begins by receiving an interference report for each user. The average noise rise for each user calculated and congestion relieving measures are implemented based upon the average noise rise and the WTRU battery level. A method for congestion control in the downlink of a wireless communication system having a WTRU and a RNC begins by receiving a transmission power report for each user. The transmission power for each user is calculated, and congestion relieving measures are implemented based upon the average transmission power and the WTRU battery level.

Abstract: A method for scheduling RRM procedures in a wireless communication system begins by receiving at least one trigger, each trigger being associated with at least one RRM procedure. A radio link is placed into a busy state, whereby the radio link is accessible only by a currently executing RRM procedure. The RRM procedure is performed on the radio link, and a set of predicted measurements is prepared for use by the other RRM procedures. The radio link is placed into an idle state, whereby the radio link is accessible by any RRM procedure.
