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： A method and apparatus for selecting a transport format combination (TFC) are disclosed. A TFC recovery and elimination unit generates an allowed transport format combination set (TFCS) subset by recovering supported TFCs and eliminating not supported TFCs based on allocated radio resources and parameters that are new. A multiplexing and transmission sequence number (TSN) setting unit generates a medium access control (MAC) protocol data unit (PDU) by multiplexing at least one higher layer PDU within a maximum supported MAC PDU size. A TFC selection and padding unit selects a TFC for the MAC PDU from the allowed TFCS subset and performs padding of the MAC PDU, if necessary, so that the MAC PDU fits into the selected TFC. For retransmission, a new allowed TFCS subset may be generated based on new radio resources and parameters and the MAC PDU may be fragmented.

摘要： A method and system for supporting multiple hybrid automatic repeat request (H-ARQ) processes per transmission time interval (TTI) are disclosed. A transmitter and a receiver include a plurality of H-ARQ processes to transmit and receive multiple transport blocks (TBs) simultaneously per TTI. The transmitter generates a plurality of TBs and assigns the TBs to multiple H-ARQ processes. The transmitter sends control information for the TBs and H-ARQ processes associated with the TBs to the receiver. The transmitter then sends the TBs using multiple H-ARQ processes simultaneously per TTI. After receiving the TBs, the receiver sends feedback to each of the TBs indicating successful or unsuccessful receipt of each of the TBs to the transmitter.

摘要： The present invention is a method and apparatus for resource allocation signaling for grouping user real time services. Uplink signaling for voice activity reporting of each user's transition between an active state and an inactive voice state is sent from a wireless transmit/receive unit to a Node B. Radio resource allocation to users of a wireless communication system varies based on user measurement reporting, a pre-determined pattern such as frequency hopping, or a pseudorandom function. Grouping methods are adjusted to better utilize the voice activity factor, so that statistical multiplexing can be used to more efficiently utilize physical resources.

摘要： Each of a plurality of packets in a particular flow is classified into one of a plurality of quality of service (QoS) classes based on information about each packet. Each packet is then adaptively processed based on the QoS class for each packet. The classification may be performed based on media information included in a session description protocol (SDP) messaging. The classification may also be performed based on a real-time transmit protocol (RTP) payload, an RTP header, a transmission control protocol (TCP) header, a user datagram protocol (UDP) header, and an Internet protocol (IP) header. The packets may be transmitted using multiple system architecture evolution (SAE) radio bearers each of which is used to deliver differentiated QoS requirements. The packets may be mapped to eigen-modes based on the QoS class of each packet such that a packet requiring a higher level of QoS is mapped to a stronger eigen-mode.

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 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.

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.
