Abstract: 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.

Abstract: Ciphering control and synchronization for both U-plane data and C-plane signaling messages in a wireless communication network are disclosed. Ciphering entities are located in a wireless transmit/receive unit (WTRU) and a network. The ciphering entities of the WTRU and the network perform ciphering control and ciphering parameter synchronization. The ciphering may be performed with a packet data convergence protocol (PDCP) layer sequence number (SN) for user plane data, a non-access stratum SN, a radio resource control SN, or an encryption SN for a control plane message. Alternatively, the ciphering control and ciphering parameter synchronization may be performed by PDCP entities of the WTRU and the network. For ciphering parameter synchronization, HFN and SN synchronization and counter check procedures are performed by the WTRU and the network based on a synchronization command message, sequence number window information, or a counter check message exchanged between the WTRU and the network.

Abstract: 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.

Abstract: 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.

Abstract: A method and system for adjusting uplink transmission timing when sending an initial transmission to a target cell/Node-B of an evolved universal terrestrial radio access network (E-UTRAN) immediately after handover from a source cell/Node-B of the E-UTRAN. In one embodiment, a user equipment (UE) autonomously computes and applies a timing advance (TA) value based on the current source cell/Node-B timing value, cell/Node-B beacon channel reference signal measurements and knowledge of the relative time difference, (if any), between the source and target cells/Node-Bs. In another embodiment, the UE sends a scheduling request message or real data packets with the computed TA value applied to the uplink transmission timing to the E-UTRAN via pre-allocated non-contention based uplink radio resources. In an alternate embodiment, the UE sends a scheduling request message with the new computed TA value applied to the UL transmission timing to an E-UTRAN via a synchronous random access channel (RACH).

Abstract: A method and apparatus for scheduling transmissions via an enhanced dedicated channel (E-DCH) are disclosed. A scheduled powe (240) is calculated for scheduled data flows. A remaining transmit power (265) is calculated for the E-DCH transmission.

Abstract: In a radio access network (300), novel system and methods reduce processing delay, and inprove integration with IP networks, by separating user data (325) from connection management and control data (329) at a node B (310) or at a base station. The user data are (325) routed to an IP(Internet Protocol) switch (309), whereas the connection management and control data (329) are routed to a centralized radio network controller (RNC) (303). Pursuant to a second embodiment of the invention, a centralized RNC provides improved radio resource management (RRM) functionality by handling all the connection management and control data for a plurality of the nodes B's, thereby simplifying the switching of the user data throughout the radio access network. Pursuant to a third embodiment of the invention, a smart IP swicth is equipped to swicth user data without core network (CN) involvement. Downlink user data are switched independently of uplink user data.
