    • 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 also device 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.
    • 提供了一种在包括物理(PHY)层,介质访问控制(MAC)层和更高层的处理层的层次中处理通信数据的无线发射接收单元(WTRU)和方法。 MAC层传输格式选择设备基于从较高层接收的数据特性和从PHY层接收的物理资源信息,定义较高层传输数据到并行数据流的分配。 传输格式选择还可以为每个数据流生成传输格式参数。 复用器组件根据由传输格式选择装置产生的数据流分配和相应的传输格式参数,将传输数据复用到传输块中的并行数据流上,并将有选择地复用的传输数据输出到PHY层,以便在相应的 物理资源分区。 优选地,传输格式选择装置还生成诸如调制和编码率(MCR),每个传输时间间隔(TTI)的子帧数量,TTI的持续时间,传输功率和混合自动重传请求(HARQ)参数的物理传输属性。

    • A method and apparatus for uplink synchronization during handover are disclosed. A wireless transmit/receive unit (WTRU) measures a downlink receipt timing difference between a source Node-B and a target Node-B. The WTRU calculates a target Node-B timing advance value based on the downlink receipt timing difference, a source Node-B timing advance value, and a relative downlink transmit timing difference between the target Node-B and the source Node-B. The WTRU then applies the target Node-B timing advance value in transmission to the target Node-B. The source Node-B may calculate the relative downlink transmit timing difference between the target Node-B and the source Node-B, and send it to the WTRU. The source Node-B may provide the source Node-B timing advance value more frequently during handover. The WTRU may measure the downlink receipt timing difference by averaging multiple first significant paths (FSPs) over a certain time window.
    • 公开了一种在切换期间上行链路同步的方法和装置。 无线发射/接收单元(WTRU)测量源节点B和目标节点B之间的下行接收定时差。 WTRU基于目标节点B和源节点B之间的下行接收定时差,源节点B定时提前值和相对下行链路传输定时差来计算目标节点B定时提前值。 然后,WTRU将传输中的目标节点B定时提前值应用于目标节点B。 源节点B可以计算目标节点B和源节点B之间的相对下行链路传输定时差,并将其发送到WTRU。 源节点B可以在切换期间更频繁地提供源节点B定时提前值。 WTRU可以通过在特定时间窗口上平均多个第一有效路径(FSP)来测量下行链路接收定时差异。
