    • An arrangement (900), method and unit for AFC in a communication system (100) having: a frequency estimator (980) producing a decision-directed frequency estimate from a received signal; and an AFC loop receiving the decision-directed frequency estimate and performing therewith frequency control. The AFC process may use a CRC-decision directed frequency estimate as the final stage in a multi-stage AFC process (preceded by SCH- and midamble-derived frequency estimate stages), such that a verified received data sequence is used to re-construct a local copy of the ideal received data symbols expected at the output of a detector. This local copy is then correlated with the actual detector output and the results used to estimate the frequency error present on the received signal. The AFC process is inherent suited for discontinuous receive (DRX) applications. This provides the advantage of allowing required frequency correction accuracy to have minimal impact on the error rate of the received data in various channel configurations.
    • 一种用于通信系统(100)中的AFC的装置(900),方法和单元,具有:频率估计器(980),从接收到的信号产生决策频率估计; 以及接收决策导频的频率估计并执行频率控制的AFC回路。 AFC过程可以使用基于CRC判决的频率估计作为多阶段AFC过程的最后阶段(先前由SCH和中间码导出的频率估计阶段),使得验证的接收数据序列被用于重构 在检测器的输出处期望的理想接收数据符号的本地副本。 然后将该本地拷贝与实际的检测器输出和用于估计接收信号上存在的频率误差的结果相关联。 AFC过程固有地适用于不连续接收(DRX)应用。 这提供了允许所需频率校正精度在各种信道配置中对接收到的数据的错误率具有最小影响的优点。

    • In a CDMA system (100), two chip rates in a TDD cell are supported by: transmitting signals in the system in a frame (400) having a plurality of timeslots; operating at least a first one (0-8) of the plurality of timeslots in the frame at a lower chip rate; and operating at least a second one (9-14) of the plurality of timeslots in the frame at a higher chip rate. This provides the following advantages: provides backwards compatibility of a network including higher chip rate functionality with existing lower chip rate user equipment; allows greater network capacity during the transition phase from a low chip rate network to a high chip rate network; and allows a network operator with a high chip rate network to provide service to roaming users from low chip rate networks.

    • An apparatus for use in allocating resource in a wireless communication system employing transfer communication protocol (TCP) based data transfer between a network and a wireless subscriber communication unit comprises a scheduler located in the network, wherein the scheduler buffers a TCP data segment for downlink (DL) transmission. A transmitter is arranged to transmit the buffered TCP data segment to the UE; wherein the message indicates an allocation of DL resources plus sufficient uplink resources to transfer a stand-alone ACK data segment. In this manner, for example in large bulk data transfer cases, a reduced latency may be achieved that may lead to improved throughput, due to the fact that the overall throughput may be limited by the window size (i.e. number of unacknowledged segments) rather than the throughput possible across the air interface.
    • 一种在网络与无线用户通信单元之间采用基于传输通信协议(TCP)的数据传输的无线通信系统中分配资源的装置包括位于网络中的调度器,其中调度器缓冲用于下行链路的TCP数据段( DL)传输。 发射机被布置为将缓冲的TCP数据段发送到UE; 其中所述消息指示DL资源的分配加上足够的上行链路资源以传送独立的ACK数据段。 以这种方式,例如在大批量数据传输情况下,可以实现降低的等待时间,这可能导致改进的吞吐量,这归因于总体吞吐量可能受到窗口大小(即未确认段的数量)的限制,而不是 通过空中接口的吞吐量。
