    • 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.
    • 公开了一种用于多媒体广播多播服务(MBMS)的资源管理方法和装置。 无线发射/接收单元(WTRU)向网络发送测量报告和MBMS接收性能报告。 可以基于小区重选信息,WTRU宏分集MBMS接收性能,由WTRU报告的相邻小区信号强度,由WTRU测量的干扰等级,小区中的WTRU数量,服务等级来进行单频网络(SFN)区域改变 优先级,WTRU级别,WTRU移动性趋势,到蜂窝中心的WTRU位置,WTRU MBMS接收干扰级别等。MBMS服务开/关决定和/或点到点(PTP)到点对多点(PTM )可以基于WTRU的信道状况进行切换。 可以基于WTRU在MBMS接收中是同步还是不同步,在特定时间窗内的连续否定确认(NAK),来自参考信道的测量路径损耗等来确定信道条件。
