摘要： A method and system for scheduling uplink transmissions in a single carrier frequency division multiple access (SC-FDMA) system are disclosed. A Node-B receives a scheduling request from a wireless transmit/receive unit (WTRU). The Node-B selects at least one subcarrier block having a certain bandwidth for the WTRU based on quality of service (QoS) requirement of the WTRU. If the QoS requirement is high, the Node-B selects at least one subcarrier block having a large bandwidth and if the QoS requirement is low, the Node-B selects at least one subcarrier block having a small bandwidth. The Node-B then schedules uplink transmissions in a time domain and/or a frequency domain based on a predetermined factor. The Node-B may perform frequency and/or time hopping in scheduling the uplink transmissions.

摘要： A method and apparatus for random access in an evolved universal terrestrial radio access (E-UTRA) system are disclosed. For code division multiplexing (CDM), a basic preamble is generated using a constant amplitude zero auto-correlation (CAZAC) sequence. The basic preamble is repeated for M time for generating a random access channel (RACH) preamble. For time division multiplexing/frequency division multiplexing (TDM/FDM), an extended CAZAC sequence is used to generate the basic preamble. Alternatively, a hybrid RACH access period including at least one CDM random access slot and at least one TDM/FDM random access slot may be provided. For synchronized random access, a RACH burst including a preamble part, a message part, and two cyclic prefixes may be generated and transmitted

摘要： A lens cleaning kit includes an elongate front housing member. The front housing member has an open front end and a closed rear end. The front housing member defines an applicator receiving space therein. The lens cleaning kit also includes a cleaning liquid applicator formed as an elongate liquid absorbing block that absorbs and retains a liquid cleaning agent. The liquid applicator has a retaining portion fittingly disposed in the applicator receiving space and an applying end portion that extends out of the applicator receiving space through the open front end of the front housing member. The liquid applicator can apply liquid cleaning agent on a lens surface to be cleaned when the applying end portion of the liquid applicator is rubbed on the lens surface. The retaining portion of the liquid applicator can be drawn out of the applicator receiving space by pulling the applying end portion in the longitudinal direction to expose a section of the retaining portion, such that, when the applying end portion becomes soiled, the applying end portion can be cut off from the retaining portion. The section of the retaining portion exposed from the applicator receiving space can serve as a new applying end portion of the liquid applicator. A front cover member is removably mounted on the front housing member to cover the applying end portion of the liquid applicator.

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.

摘要翻译： 公开了一种在切换期间上行链路同步的方法和装置。 无线发射/接收单元（WTRU）测量源节点B和目标节点B之间的下行接收定时差。 WTRU基于目标节点B和源节点B之间的下行接收定时差，源节点B定时提前值和相对下行链路传输定时差来计算目标节点B定时提前值。 然后，WTRU将传输中的目标节点B定时提前值应用于目标节点B。 源节点B可以计算目标节点B和源节点B之间的相对下行链路传输定时差，并将其发送到WTRU。 源节点B可以在切换期间更频繁地提供源节点B定时提前值。 WTRU可以通过在特定时间窗口上平均多个第一有效路径（FSP）来测量下行链路接收定时差异。

摘要： A clamping tool includes a clamping member with a tubular body and resilient clamping jaws extending integrally from the tubular body and cooperatively defining a clamping hole. The clamping jaws have inclined outer surfaces which incline radially and outwardly in a direction away from the tubular body. An adjustment sleeve is sleeved on the tubular body, and has a depressing section disposed proximate to the clamping jaws, and a threaded section that is formed with an internal screw thread which engages an external screw thread on an outer surface of the tubular body. Due to the engagement between the internal screw thread and the external screw thread, the depressing section is moved along the inclined outer surfaces of the clamping jaws, and depresses the clamping jaws to permit adjustment of size of the clamping hole when the adjustment sleeve is rotated about the clamping member.
