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.

Systems and methods are provided for using a light weight protocol (LWP) and protocol agent in a network communication system. A protocol agent receives a message in LWP from an end node. The message in LWP is directed to a destination network node that uses a network protocol that the end node is incapable of supporting, such as Hypertext Transfer Protocol (HTTP), Real Time Streaming Protocol (RTSP), Session Initiation Protocol (SIP) or other network protocols. The protocol agent determines a network protocol to map the message to, and generates a message in the determined network protocol based on the received LWP message. The protocol agent then sends the generated message to the destination network node.

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 transmission of MBMS data synchronously in multiple cells of the same single frequency network (SFN). The MBMS multi-cell coordination 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 controlling radio network controller (C-RNC) for use in radio resource management (RRM) functions includes a radio resource management function for managing radio resources. The RRM function uses data stored in a common database, including cell data and wireless transmit/receive unit (WTRU) data. The cell data includes resource assignment information for a cell, and the WTRU data includes WTRU capability and WTRU radio link information.

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. 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. The user is associated with a particular category of time slots based on the QoS information of the user.

A method for determining whether a data transmission rate in a wireless communication system is appropriate for current system conditions begins by calculating a frame error rate (FER) for a given period of time and obtaining a current data rate. If the current data rate is greater than a minimum data rate and the FER is a high value, then the system switches to a lower data rate. If the current data rate is greater than a minimum data rate and the FER is less than a high value, then the system maintains the current data rate. If the current data rate is less than a maximum data rate and the FER is a low value, then the system determines whether a higher data rate can be used.

A method and apparatus for managing common measurement gaps in multimedia broadcast multicast services (MBMS) cells are described. In one embodiment, a broadcast channel (BCH) common measurement gap is determined for use by a plurality of wireless transmit/receive units (WTRUs) in an MBMS cell. The BCH common measurement gap is assigned to the WTRUs, and the BCH common measurement gap is transmitted to the WTRUs. In another embodiment, a paging channel (PCH) common measurement gap is determined for use by a plurality of WTRUs in an MBMS cell. The PCH common measurement gap is assigned to the WTRUs, and the PCH common measurement gap is transmitted to the WTRUs.
摘要:
The present invention is related to a method and system for sending and reducing uplink feedback signaling by a wireless transmit/receive unit (WTRU) related to transmission of multimedia broadcast multicast service (MBMS) data over a high speed downlink packet access (HSDPA) channel. A Node B may pre-allocate a time/frequency region or a common channelization code for the feedback. A triggering criterion for reporting a channel quality indicator (CQI) is set and WTRUs send a CQI to a Node B only if the triggering criterion is satisfied. The triggering criterion may be a current operating CQI value at the Node B, or based on erroneous transport block reception statistics, or a predetermined time period. A feedback reduction method related to ACK/NACK includes the WTRU sending an indication of an average number of transmissions needed to successfully decode the data instead of sending an ACK/NACK for every transmission interval.
