摘要： A method and apparatus for assigning automatic repeat request (ARQ)/hybrid-automatic repeat request (H-ARQ) processes in a wireless transmit/receive unit (WTRU) to support enhanced uplink (EU) data transmissions. After parameters associated with the ARQ/H-ARQ processes are configured, the WTRU assigns an ARQ/H-ARQ process for selected data. After transmitting the data, the WTRU determines whether feedback information for the data has been received. The WTRU releases the ARQ/H-ARQ process if an acknowledgement (ACK) message has been received, and retransmits the data if a non-acknowledgement (NACK) message or no feedback information has been received in a predetermined time period while incrementing a transmission counter in the WTRU. When an ARQ/H-ARQ transmission limit has been reached, the WTRU may discard the data or reinitiate the transmission. An ARQ/H-ARQ process assigned for transmission of lower priority data may be preempted for transmission of higher priority data when there is no available ARQ/H-ARQ process.
摘要翻译：一种用于在无线发射/接收单元（WTRU）中分配自动重复请求（ARQ）/混合自动重传请求（H-ARQ）过程以支持增强上行链路（EU）数据传输的方法和装置。在配置与ARQ / H-ARQ进程相关的参数后，WTRU为所选数据分配ARQ / H-ARQ进程。在发送数据之后，WTRU确定是否已经接收到用于数据的反馈信息。如果已经接收到确认（ACK）消息，则WTRU释放ARQ / H-ARQ过程，并且如果在预定时间段内已经接收到未确认（NACK）消息或没有反馈信息，同时递增传输，则重新发送数据计数器。当达到ARQ / H-ARQ传输限制时，WTRU可以丢弃数据或重新发送传输。当没有可用的ARQ / H-ARQ过程时，分配用于传输较低优先级数据的ARQ / H-ARQ进程可以被抢占用于传输较高优先级数据。

摘要： A wireless communication method and apparatus for coordinating Node-Bs during handover for enhanced uplink (EU) transmission. In one embodiment, a radio network controller (RNC) initiates an inter-Node-B soft handover. A wireless transmit/receive unit (WTRU) establishes communication connections with a plurality of Node-Bs. A particular one of the Node-Bs is designated as being a primary Node-B, and each of other Node-Bs are designated as being a non-primary Node-B. The RNC informs all of the Node-Bs that the particular Node-B is a primary Node-B. The primary Node-B schedules EU transmission and performs ACK/NACK during soft handover. In another embodiment, the RNC initiates a hard handover for a WTRU connected to a source Node-B. The RNC sends an activation timer to the source Node-B to set the time for handover. As many previously negatively acknowledged (NACKed) data packets as possible are prioritized for retransmission in the source Node-B before the activation timer expires.

摘要： 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.

摘要： A method and apparatus for implementing data security and automatic repeat request (ARQ) in a wireless communication system are disclosed. Cipher entities are included in a wireless transmit/receive unit (WTRU) and an access gateway (aGW), and outer ARQ, (or radio link control (RLC)), entities are included in the WTRU and an evolved Node-B (eNode-B). Each cipher entity is located on top of an outer ARQ entity. The cipher entities cipher and decipher a data block by using a generic sequence number (SN) assigned to the data block. The outer ARQ entities may segment the ciphered data block to multiple packet data units (PDUs), may concatenate multiple ciphered data blocks to a PDU, or may generate one PDU from one data block. The outer ARQ entities may segment or re-segment the PDU when a transmission failure occurs.

摘要： A wireless transmit/receive unit (WTRU) includes a control plane (C-plane) packet data convergence protocol (C-PDCP) layer which performs ciphering of a signaling message. The C-PDCP layer is activated upon power up of the WTRU and initial security parameters are loaded to the C-PDCP layer. An initial connection signaling message and a user identity are ciphered using the initial security parameters even before the WTRU is authenticated. The initial security parameters including a ciphering key (CK) may be generated from system information broadcast from the network. The CK may be a public key for asymmetric encryption, and may be selected from a public key set broadcast by or derived from the network system information. An index of the selected public key may be separately encoded. Alternatively, the index may be communicated by using a Diffie-Hellman key exchange method.

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.
