摘要:
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.; The method involves sending a measurement request message from a source node to an intermediate node. The measurement request message is forwarded to a next hop node, when the intermediate node receives the measurement request message. Measurements are conducted by the intermediate node, where the intermediate node sends a measurement report message back to the source node. The measurements are conducted by a final destination node, and a measurement report message is sent to the source node. An independent claim is also included for a communication system for collecting and reporting measurement results, comprising a source node for sending a measurement request message to an intermediate node.

A wireless communication system including at least one IEEE 802 multi-stack wireless transmt/receive unit (WTRU) and a plurality of technologically diversified acess networks, such as IEEE 802.X networks and Third Generation Partnership Project (3GPP) networks, that are concurrently deployed. Both the multi-stack WTRU and the technologically diversified networks includ a media indipendent handover (MIH) function. The WTRU is configured to read MIH information transmitted from one of the IEEE 802.X networks, trigger 3GPP authentication and atuhorization procedures based on the MIH information, obtain a local Internet Protocol (IP) address, establish a tunnel to a packet data gateway (PDG) un a 3GPP core network, constructed a care of address (CoA) and register the CoA with a home agent of the WTRU, whereby data destined for the WTRU is routed via the home agent through a new tunnel established between the home agent and a foreign agent based on the CoA.

The present invention relates to a method for confirming the delivery of a data packet in a mesh network by sending an acknowledgement (ACK) to an ingress mesh point (IMP). A mesh network comprises a plurality of mesh points that are wirelessly linked together. A data packet sent by a station (STA) is received by an IMP. A MAC frame is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (EMP) in order to provide a service by the mesh network. The MAC frame includes a field comprising an IMP address and an EMP address. When the EMP, (or optionally an intermediate mesh point), receives a data packet successfully, the EMP or the intermediate mesh point sends an ACK to the IMP or preceding mesh point.

The present invention is related to a method and system for multi-cell coordination for multimedia broadcast multicast services (MBMS) in a wireless communication system. An MBMS multi-cell coordination unit is provided to coordinate a plurality of evolved Node-Bs (eNodeBs) for transmisstion of MBMS data synchronously in multiple cells of the same single frequencty network (SFN). The MBMS multi-cell coorditaion unit may be located in an access gateway or in an eNodeB. An MBMS multi-cell scheduling scheme may be preconfigured for the eNodeBs for synchronization. Alternatively, the eNodeBs may be synchronized dynamically.

A wireless transmit/receive unit, WTRU, is disclosed comprising a transmitter configured to transmit a message from a radio resource controller, RRC, wherein the message is a RRC Codec Report message including AMR codec information in the WTRU, and a receiver configured to receive a message at the RRC upon triggering RRC codec rate control in a radio network controller, RNC, wherein the message is a RRC Codec Rate Control message that is incorporated into an existing RRC message and requests an adaptive multi-rate, AMR, change of the RRC codec rate. Furthermore, a radio network controller, RNC, is disclosed comprising a receiver configured to receive a message from a radio resource controller, RRC, in a wireless transmit/receive unit, WTRU, wherein the message is a RRC Codec Report message including AMR codec information in the WTRU, and a transmitter configured to transmit a message to the RRC in the WTRU upon triggering RRC codec rate control in the RRC of the RNC, wherein the message is a RRC Codec Rate Control message that is incorporated into an existing RRC message and requests an adaptive multi-rate, AMR, change of the RRC codec rate.

In a wireless communication system including an access point and at least one wireless transmit/receive unit (WTRU), a method for adaptive radio resource management begins by examining a frame error rate value of a WTRU. Then, a channel utilization value of the WTRU and a current data rate of the WTRU are examined. System parameters for the WTRU are adjusted based on the examined variables.
