    • A method and apparatus of resource management for multimedia broadcast multicast services (MBMS) are disclosed. A wireless transmit/receive unit (WTRU) sends a measurement report and an MBMS reception performance report to a network. Single frequency network (SFN) area change may be made based on cell reselection information, WTRU macro-diversity MBMS reception performance, neighbor cell signal strength reported by a WTRU, interference level measured by the WTRU, a number of WTRUs in a cell, service priority, WTRU class, WTRU mobility trend, WTRU location to a cell center, WTRU MBMS reception interference level, etc. The MBMS service on/off decision and/or point-to-point (PTP) to point-to-multipoint (PTM) switching may be made based on a channel condition of a WTRU. The channel condition may be determined based on whether the WTRU is in in-sync or out-of-sync in MBMS reception, consecutive negative acknowledgements (NAKs) within a certain time window, measured pathloss from a reference channel, etc.

    • Methods and apparatus for performing efficient blind transport format (TF) detection in wireless communication systems are disclosed based on TF groups and efficient hybrid automatic repeat request (HARQ) assisted blind TF detection for retransmissions. When a receiver detects a failure for an initial transmission, a transmitter receives an HARQ negative acknowledgement (NACK) or no feedback from the receiver beyond a certain duration. The transmitter uses the same transport format combination (TFC) for a first retransmission as is used for the initial transmission for data detection, and if the first retransmission fails and after the transmitter gets the HARQ NACK or no feedback from the receiver beyond the certain duration, the transmitter uses a next more robust TFC for a second retransmission and the receiver should also to use next more robust TFC for data detection for the second retransmission from the transmitter. Alternatively, the transmitter uses the next robust TF for the first retransmission.

    • A method and system for performing handover in a third generation (3G) long term evolution (LTE) system are disclosed. A source evolved Node-B (eNode-B) makes a handover decision based on measurements and sends a handover request to a target eNode-B. The target eNode-B sends a handover response to the source eNode-B indicating that a handover should commence. The source eNode-B then sends a handover command to a wireless transmit/receive unit (WTRU). The handover command includes at least one of reconfiguration information, information regarding timing adjustment, relative timing difference between the source eNode-B and the target eNode-B, information regarding an initial scheduling procedure at the target eNode-B, and measurement information for the target eNode-B. The WTRU then accesses the target eNode-B and exchanges layer 1/2 signaling to perform downlink synchronization, timing adjustment, and uplink and downlink resource assignment based on information included in the handover command.
    • 公开了一种在第三代(3G)长期演进(LTE)系统中进行切换的方法和系统。 源演进节点B(eNode-B)基于测量进行切换决定,并向目标eNode-B发送切换请求。 目标eNode-B向源eNode-B发送指示切换应该开始的切换响应。 源eNode-B然后向无线发射/接收单元(WTRU)发送切换命令。 切换命令包括重新配置信息,关于定时调整的信息,源eNode-B和目标eNode-B之间的相对定时差异,关于目标eNode-B的初始调度过程的信息,以及用于 目标eNode-B。 然后,WTRU基于包括在切换命令中的信息来访问目标eNode-B并交换层1/2信令以执行下行链路同步,定时调整以及上行链路和下行链路资源分配。
