    • 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.
    • 基于TF组和用于重发的有效混合自动重复请求(HARQ)辅助盲TF检测,公开了在无线通信系统中执行有效的盲传输格式(TF)检测的方法和装置。 当接收机检测到初始传输失败时,发射机接收到HARQ否定确认(NACK),或者没有接收机超过一定持续时间的反馈。 发射机对于用于初始传输用于数据检测的第一次重传使用相同的传输格式组合(TFC),并且如果第一重传失败并且在发射机获得HARQ NACK之后,或者在接收机之后没有来自超过该持续时间的反馈 ,发射机使用下一个更稳健的TFC进行第二次重传,并且接收机还应该使用下一个更稳健的TFC来进行来自发射机的第二次重传的数据检测。 或者,发射机使用下一个强大的TF进行第一次重传。
