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： In a wireless communication system comprising at least one evolved Node-B (eNB) and a plurality of wireless transmit/receive units (WTRUs), a non-contention based (NCB) channel is established, maintained, and utilized. The NCB channel is allocated for use by one or more WTRUs in the system for utilization in a variety of functions, and the allocation is communicated to the WTRUs. The wireless communication system analyzes the allocation of the NCB channel as required, and the NCB channel is reallocated as required.

摘要： A receiver sends hybrid automatic repeat request (H-ARQ) feedback for a current packet and at least one previous packet, whereby an error is detected based on the H-ARQ feedback. The receiver sends H-ARQ feedback with an identification of the packet or a sequence number of a packet that the receiver expects to receive next. The receiver stores a packet in a memory before combining the packet with a previously received packet, and decodes the stored packet after failing to decode a combined packet to avoid a corruption error. The receiver may set a timer when sending a NACK. If the receiver fails to receive a packet until expiration of the timer, the receiver initiates a process for recovering the packet. Each H-ARQ feedback may be associated with other attributes. Some H-ARQ processes may operate in an asynchronous mode while others in a synchronous mode in the same direction.
摘要翻译：接收机为当前分组和至少一个先前分组发送混合自动重传请求（H-ARQ）反馈，由此基于H-ARQ反馈检测到错误。接收机发送H-ARQ反馈，其中包含分组的标识或者接收机期望接收的分组的序列号。在将分组与先前接收到的分组组合之前，接收机将分组存储在存储器中，并且在未组合分组解码之后对存储的分组进行解码以避免损坏错误。接收机可以在发送NACK时设置定时器。如果接收方在定时器到期之前无法接收到数据包，则接收方发起恢复数据包的过程。每个H-ARQ反馈可以与其他属性相关联。一些H-ARQ进程可以以异步模式工作，而其他H-ARQ进程可以在同步方向上工作。

摘要： A method and apparatus for dynamically configuring a memory for hybrid automatic repeat request (H-ARQ) processes in a receiving node to permit a more flexible H-ARQ memory configuration and improve the performance of H-ARQ processes. An H-ARQ memory in the receiving node is reserved for a plurality of H-ARQ processes. A transmitting node dynamically configures the H-ARQ memory in the receiving node for each H-ARQ transmission so that the memory requirement for a plurality of H-ARQ processes exceeds the H-ARQ memory capacity. If there is insufficient H-ARQ memory available to support H-ARQ transmissions, only a subset of the plurality of H-ARQ processes may be activated at a time. When there is insufficient H-ARQ memory for processing H-ARQ transmissions, a negative acknowledgement (NACK), an acknowledgement (ACK), nothing, and/or information indicating the reason for a failed transmission may be transmitted to a transmitting node.
摘要翻译：一种用于在接收节点中动态配置用于混合自动重传请求（H-ARQ）进程的存储器以允许更灵活的H-ARQ存储器配置并提高H-ARQ进程的性能的方法和装置。接收节点中的H-ARQ存储器被保留用于多个H-ARQ进程。发送节点为每个H-ARQ传输动态地配置接收节点中的H-ARQ存储器，使得多个H-ARQ过程的存储器需求超过H-ARQ存储器容量。如果没有足够的H-ARQ存储器来支持H-ARQ传输，则可以一次仅激活多个H-ARQ过程的一个子集。当用于处理H-ARQ传输的H-ARQ存储器不足时，可以向发送节点发送否定确认（NACK），确认（ACK），无和/或指示发送故障的原因的信息。

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.
摘要翻译：公开了一种用于选择传输格式组合（TFC）的方法和装置。 TFC恢复和消除单元通过恢复支持的TFC并基于分配的无线电资源和新的参数消除不支持的TFC来生成允许的传输格式组合集（TFCS）子集。复用和发送序列号（TSN）设置单元通过在最大支持的MAC PDU大小内复用至少一个较高层PDU来生成媒体访问控制（MAC）协议数据单元（PDU）。 TFC选择和填充单元从允许的TFCS子集中选择用于MAC PDU的TFC，并且如果需要，则执行MAC PDU的填充，使得MAC PDU适合于所选择的TFC。对于重传，可以基于新的无线电资源和参数来生成新的允许的TFCS子集，并且MAC PDU可能被分段。

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.
