    摘要： 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.

    摘要： A method and apparatus are disclosed relating to ciphering and de-ciphering of packet units in wireless devices during retransmission in wireless communications. The packet units are re-segmented with the ciphering done on the re-segmented packet unit or on a radio link control protocol data unit (RLC PDU) with or without segmentation. Alternatively, the re-segmentation is done on the radio link control service data unit (RLC SDU) with or without segmentation. Alternatively, the ciphering process and multiplexing of the RLC PDU is done in the medium access control (MAC) layer of a MAC PU before undergoing a hybrid automatic repeat request (HARQ) process for retransmission. Further, the ciphering process in the RLC is done on a packet data convergence protocol packet data unit (PDCP PDU).

    摘要： A method and apparatus are described for implementing a reset procedure for radio link control (RLC) using radio resource control (RRC) signaling. A wireless transmit/receive unit (WTRU) receives a request for RLC reset. A processor at the WTRU comprises a RRC entity and a RLC entity. The RRC entity receives the request for a RLC reset in a radio resource control message. The RLC entity reassembles RLC service data units (SDUs) from any protocol data units (PDUs) that are received out of sequence at a receiving side of the RLC entity. The reassembled SDUs are delivered in sequence to a packet data convergence protocol entity (PDCP). At the receiving side of the RLC entity, any remaining PDUs that are not able to be reassembled are discarded. At a transmitting side of the RLC entity, all SDUs and PDUs stored in transmit buffers are discarded.
