摘要： 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.

摘要： A method and apparatus for selecting multiple transport formats and transmitting multiple transport blocks (TBs) in a transmission time interval simultaneously with, multiple hybrid automatic repeat request (H-ARQ) processes in a wireless communication system are disclosed. Available physical resources and H-ARQ processes associated with the available physical resources are identified and channel quality of each of the available physical resources is determined. Quality of service (QoS) requirements of higher layer data to be transmitted are determined. The higher layer data is mapped to at least two H-ARQ processes. Physical transmission and H-ARQ configurations to support QoS requirements of the higher layer data mapped to each H-ARQ process are determined. TBs are generated from the mapped higher layer data in accordance with the physical transmission and H-ARQ configurations of each H-ARQ process, respectively. The TBs are transmitted via the H-ARQ processes simultaneously.

摘要： A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.
摘要翻译：节点B向无线发射/接收单元（WTRU）发送轮询消息。 WTRU响应于轮询消息发送上行链路同步突发，而没有竞争。节点B基于同步突发来估计上行链路时移，并向WTRU发送上行链路时序调整命令。 WTRU然后基于上行链路定时调整命令来调整上行链路定时。备选地，节点B可以向WTRU发送用于上行链路同步的调度消息。 WTRU可以基于调度消息发送同步突发。或者，WTRU可以在从节点B接收到同步请求之后执行基于竞争的上行链路同步。 WTRU可以进入空闲状态，而不是在WTRU移动到新小区时执行到新小区的切换。 WTRU的不连续接收（DRX）间隔可以基于WTRU的活动来设置。

摘要： A method and apparatus of adaptive sequence numbering in a wireless communication system includes determining whether or not a packet to be transmitted will be segmented. Based upon the segmentation determination, a determination as to whether or not to include a radio link controller (RLC) specific automatic repeat request (ARQ) sequence number (SN) to the packet is made. An indicator is added to indicate whether or not the RLC-specific ARQ SN is included in the packet. The packet is transmitted, and an acknowledgment (ACK) is received for the transmitted packet.

摘要： A wireless transmit receive unit (WTRU) and method are provided that process communication data in a hierarchy of processing layers including a physical (PHY) layer, a medium access control (MAC) layer and higher layers. A MAC layer transport format selection device defines an assignment of higher layer transmission data to parallel data streams based on data characteristics received from higher layers and physical resource information received from the PHY layer. The transport format selection device also generates transport format parameters for each data stream. A multiplexer component multiplexes the transmission data onto the parallel data streams in transport blocks in accordance with the data stream assignment and the respective transport format parameters generated by the transport format selection device and outputs the selectively multiplexed transmission data to the PHY layer for transmission over respective physical resource partitions. Preferably, the transport format selection device also generates physical transmission attributes such as modulation and coding rate (MCR), number of subframes per transmission time interval (TTI), duration of TTI, transmission power and hybrid automatic repeat request (HARQ) parameters.

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 variety of wireless communication methods and apparatus for supporting reconfiguration of radio link control (RLC) parameters are disclosed. A radio resource control (RRC) reconfiguration message is generated that indicates that an RLC unit in a wireless transmit/receive unit (WTRU) or a universal terrestrial radio access network (UTRAN) should be reconfigured from supporting flexible size RLC protocol data units (PDUs) to supporting fixed size RLC PDUs. If an information element (IE) "one sided RLC re-establishment" is present in the RRC reconfiguration message, only a receiving side subassembly in the RLC unit is re-established. Otherwise, both the receiving side subassembly and a transmitting side subassembly in the RLC unit are re-established. Flexible size RLC PDUs may be discarded and a message indicating the discarded flexible size RLC PDUs may be transmitted. The flexible size RLC PDUs may be modified such that they correspond to a set of pre-defined sizes.
