摘要： A method and apparatus for uplink synchronization during handover are disclosed. A wireless transmit/receive unit (WTRU) measures a downlink receipt timing difference between a source Node-B and a target Node-B. The WTRU calculates a target Node-B timing advance value based on the downlink receipt timing difference, a source Node-B timing advance value, and a relative downlink transmit timing difference between the target Node-B and the source Node-B. The WTRU then applies the target Node-B timing advance value in transmission to the target Node-B. The source Node-B may calculate the relative downlink transmit timing difference between the target Node-B and the source Node-B, and send it to the WTRU. The source Node-B may provide the source Node-B timing advance value more frequently during handover. The WTRU may measure the downlink receipt timing difference by averaging multiple first significant paths (FSPs) over a certain time window.

摘要： A method and apparatus of adaptive sequence numbering in a wireless communication system includes determining whether or not a packet to be transmitted will be segmented. Based upon the segmentation determination, a determination as to whether or not to include a radio link controller (RLC) specific automatic repeat request (ARQ) sequence number (SN) to the packet is made. An indicator is added to indicate whether or not the RLC-specific ARQ SN is included in the packet. The packet is transmitted, and an acknowledgment (ACK) is received for the transmitted packet.

摘要： A transmitter may instruct a receiver to move a receive window if the transmitter cannot retransmit a packet in response to an automatic repeat request (ARQ) status report and a hybrid ARQ (HARQ) feedback error report. The transmitter may advance a transmit window upon receipt of a local acknowledgement if the packet is in an ongoing flow and advance the transmit window when the packet is acknowledged by a status report if the packet is an isolated packet. The transmitter may perform a retransmission based on context in which the retransmission is requested. The transmitter may send an acknowledgement to the status report or the HARQ feedback error report. The transmitter may specify whether an HARQ feedback error report or a status report is allowed. The receiver may adjust the level of robustness and error protection for the HARQ feedback based on an indication from the transmitter.
摘要翻译：如果发射机响应于自动重发请求（ARQ）状态报告和混合ARQ（HARQ）反馈错误报告而不能重传分组，则发射机可以指示接收机移动接收窗口。如果分组处于正在进行的流中，则发送器可以在接收到本地确认时提前发送窗口，并且如果分组是孤立分组，则当分组被状态报告确认时，推进发送窗口。发射机可以基于请求重传的上下文来执行重传。发射机可以向状态报告或HARQ反馈错误报告发送确认。发射机可以指定是否允许HARQ反馈错误报告或状态报告。接收机可以基于来自发射机的指示来调整HARQ反馈的鲁棒性和错误保护级别。

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： 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.

摘要： 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).

摘要： A wireless communication method and apparatus for detecting and decoding enhanced dedicated channel (E-DCH) hybrid automatic repeat request (H-ARQ) indicator channel (E-HICH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-HICH transmissions and detects an H-ARQ indicator transmitted via the E-HICH by performing a binary hypothesis test. The WTRU then generates an acknowledgement (ACK) message or a non-acknowledgement (NACK) message based on the detected H-ARQ indicator. A reliability test may be further performed to improve performance, whereby the binary hypothesis test may be performed only if the reliability test is passed.

摘要： A method implemented in a wireless communication system including a wireless transmit/receive unit (WTRU), a Node-B and a radio network controller (RNC) for quantizing multiplexed data allowed by grants to closely match a selected enhanced uplink transport format combination (E-TFC) transport block size is disclosed. The amount of scheduled and non-scheduled data allowed to be transmitted is quantized so that the amount of data multiplexed into an enhanced uplink (EU) medium access control (MAC-e) protocol data unit (PDU) more closely matches the selected E-TFC transport block size. In an embodiment, the amount of buffered data allowed to be multiplexed by at least one grant, (a serving grant and/or a non-serving grant), is quantized so that the sum of scheduled and non-scheduled data including MAC header and control information multiplexed into a MAC-e PDU more closely matches the selected E-TFC transport block size.
