    Abstract: 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.

    Abstract: A method and apparatus for indicating a transmission status to a higher layer are disclosed. In the transmitting entity, a radio link control (RLC) entity sends a packet delivery notification regarding delivery status of a higher layer message to a higher layer entity based on hybrid automatic repeat request (HARQ) feedback information obtained from an HARQ entity. The RLC entity may send the packet delivery notification to the higher layer entity based on an RLC status report. Alternatively, the HARQ entity may send the packet delivery notification to the higher layer entity and/or the RLC entity based on HARQ feedback. The higher layer entity may update the higher layer message before retransmitting the higher layer message. If the RLC entity segments an RLC service data unit (SDU) and delivery of at least one segment of the RLC SDU fails, the RLC entity may discard the RLC SDU.

    Abstract: A method and apparatus for transmitting and receiving common logical channel and dedicated logical channel transmissions via a high speed downlink shared channel (HS-DSCH) are disclosed. A medium access control (MAC)-hs entity generates a MAC-hs protocol data unit (PDU) carrying a MAC-c/sh/m PDU and/or a MAC-d PDU. A UE-specific HS-DSCH radio network temporary identifier (H-RNTI) may be used for the MAC-d PDU, and a cell-specific H-RNTI may be used for the MAC-c/sh/b PDU. Alternatively, a cell-specific H-RNTI and one of a cell RNTI (C-RNTI) and a universal terrestrial radio access network RNTI (U-RNTI) may be used in a Cell_FACH state. The logical channel type and identity may be inserted in a MAC-hs PDU header or indicated by a distinct H-RNTI. A logical channel type for common logical channels may be identified in a MAC-c/sh/m PDU header. The logical channel type and identity may be identified by a queue identity.

    Abstract: A method and system for supporting voice over Internet protocol (VoIP) services over a wireless communication network are disclosed. Data is encoded at a coding rate specified by a controller for generating a VoIP packet. Among the encoded data, bits sensitive to errors and bits not sensitive to errors are identified and error protection is performed separately by a medium access control layer and/or physical layer. A header of the VoIP packet may be selectively compressed in accordance with an indication from the controller. A user datagram protocol (UDP)-Lite may be used for partial coverage of the sensitive bits. A comfort noise may be generated by a receiving end during a silence period without receiving a comfort noise packet from a transmitting end. If the VoIP packet is not fit into a currently assigned radio resource, the VoIP packet may be fragmented.

    Abstract: Urgent data is scheduled in a wireless communication system including at least one wireless transmit/receive unit (WTRU) and at least one Node-B. The WTRU includes a re-ordering release timer. The Node-B includes a buffer, a lifespan (or maximum allowed delay) timer and a high speed downlink packet access (HSDPA) scheduler. The HSDPA scheduler determines whether there is at least one protocol data unit (PDU) in the buffer whose lifespan (maximum allowed delay) timer or re-ordering release timer will expire if the PDU is not transmitted in a next N transmission timing interval (TTI), where N is a design parameter. If so, the PDU is treated as urgent data whereby a sequence of WTRUs , (i.e., users), scheduled to receive urgent data is arranged in an order of decreasing priority, and a more conservative modulation and coding scheme (MCS), multiple code transmission and a different redundancy reversion are considered for use.
