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： Urgent data is scheduled in a wireless communication system including at least one wireless transmit/receive unit (WTRU) and at least one Node-B. The WTRU includes a re-ordering release timer. The Node-B includes a buffer, a lifespan (or maximum allowed delay) timer and a high speed downlink packet access (HSDPA) scheduler. The HSDPA scheduler determines whether there is at least one protocol data unit (PDU) in the buffer whose lifespan (maximum allowed delay) timer or re-ordering release timer will expire if the PDU is not transmitted in a next N transmission timing interval (TTI), where N is a design parameter. If so, the PDU is treated as urgent data whereby a sequence of WTRUs , (i.e., users), scheduled to receive urgent data is arranged in an order of decreasing priority, and a more conservative modulation and coding scheme (MCS), multiple code transmission and a different redundancy reversion are considered for use.

摘要： A wireless communication method and apparatus for transferring buffered enhanced uplink (EU) data from a wireless transmit/receive unit (WTRU), i.e., a mobile station, to a Node-B. The EU data is generated and stored in a buffer of the WTRU. The WTRU transmits a message to the Node-B including a request for a desired transport format combination (TFC) or data traffic indicator. The Node-B schedules one or more allowed EU data transmissions between the WTRU and the Node-B by transmitting an EU data scheduling message to the WTRU. The WTRU transmits all of the EU data stored in the buffer to the Node-B if the allowed EU data transmissions are sufficient to support transmission of all of the EU data stored in the buffer. Otherwise, the WTRU transmits a portion of the EU data along with the desired TFC or detailed traffic volume measurement (TVM) information to the Node-B.

摘要： A method and apparatus for supporting an enhanced uplink soft handover (EU-SHO) operation for a wireless transmit/receive unit (WTRU) (115). The apparatus may be a multi-cell wireless communication system (200) including at least two EU-SHO Node-Bs (210) and a radio network controller (RNC) (205). The RNC (205) includes a medium access control (MAC) entity (215) that handles enhanced uplink dedicated channel (EU-DCH) functionalities. The RNC (205) is configured according to a first architecture when an EU-SHO operation for the WTRU (115) is not taking place, and the RNC (205) is configured according to a second architecture when the WTRU (115) is operating in an EU-SHO operation. According to the second architecture, the MAC entity (215) of the RNC (205) includes an ACK/NACK generator (225) which generates signals indicating whether or not an EU transmission originating from the WTRU (115) has been successfully received by the RNC (205) and an uplink scheduler for scheduling an EU transmission for the WTRU (115).

摘要： A method and apparatus for processing data blocks during soft handover. The apparatus may be a wireless communication system including at least two enhanced uplink soft handover (EU-SHO) Node-Bs and a radio network controller (RNC). Each Node-B decodes a received data block and forwards the decoded data block to the RNC. If the RNC receives at least one copy of a successfully decoded data block, the RNC uses a re-ordering function entity to process the copy of the successfully decoded data block to support in-sequence delivery to higher protocol layers. If the RNC receives more than one copy of a successfully decoded data block, the RNC discards the extra successfully decoded data block copies. The RNC is either a serving-RNC (S-RNC) or a controllingRNC (C-RNC). Each Node-B includes a medium access control (MAC) entity that handles enhanced uplink dedicated channel (EU-DCH) functionalities.

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 processing enhanced uplink scheduling grants are disclosed. A wireless transmit/receive unit (WTRU) detects an absolute grant (AG) and a relative grant (RG). Once the WTRU detects an AG or a RG, a new serving grant (SG) is generated and a hybrid automatic repeat request process may be activated or deactivated depending on whether the received AG is a primary AG or a secondary AG, whether a scheduling mode is a primary AG mode or a secondary AG mode, whether an AG value is set to "INACTIVE" and whether a transmission time interval is 2ms or 10ms. A Node-B may send a secondary AG to the WTRU before switching from a primary AG mode to a secondary AG mode and may send the secondary AG only if there is no out-of-date secondary AG exists, which may be detected by implementing a time threshold.

摘要： A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. An enhanced uplink medium access control (MAC-e/es) entity processes a received scheduling grant to calculate a serving grant. The MAC-e/es entity determines whether both a hybrid automatic repeat request (H-ARQ) process for scheduled data and scheduled data are available. If an H-ARQ process for scheduled data and scheduled data are available, the MAC-e/es entity determines whether a serving grant exists. The MAC-e/es entity calculates a remaining power based on maximum allowed power and restricts an E-DCH transport format combination (E-TFC) based on the remaining power. The MAC-e/es entity selects an E-TFC using the serving grant and generates a MAC-e protocol data unit. The MAC-e/es entity may process the received scheduled grant is at each transmission time interval or may store the received scheduled grant in a grant list until there is E-DCH data to transmit.

摘要： A method and apparatus for identifying and reporting a non-operational enhanced uplink (EU) signaling channel. A wireless transmit/receive unit (WTRU) sends a channel allocation request for an enhanced dedicated channel (E-DCH) to a Node-B through an uplink (UL) EU signaling channel. In response to the request, the Node-B sends channel allocation information to the WTRU through one or more downlink (DL) EU signaling channels. If the WTRU does not receive the channel allocation information before a predetermined time period established by a request response timer expires, the WTRU reports a non-operational EU signaling channel to a radio network controller (RNC) via the Node-B. The Node-B reports a non-operational EU signaling channel when the Node-B does not receive E-DCH data transmissions after sending the channel allocation information, or receives subsequent E-DCH data transmissions which are inconsistent with the channel allocation information.
