    • A system and method for reducing the latency from timing deviation (TD) measurement to time advance (TA) adjustment. The invention uses a deterministic procedure to coordinate time advance (TA) commands and timing deviation (TD) measurements so that failed transmissions or mobile terminals signal propagation changes can be recognized and corrected much more rapidly. Radio resource efficiency is maximized by minimizing signalling overhead through effectively reducing the frequency of time advance commands. This is accomplished by using TA command signals which include a Connect Frame Number (CFN) to specify particular radio frames for time advance (TA) adjustment. The potential for timing deviation (TD) measurements to be incorrectly processed in conjunction with adjusting a physical reception window and calculating mobile termination location is minimized, without excessive command signaling requirements.
    • 一种用于将延迟从定时偏差(TD)测量减小到时间提前(TA)调整的系统和方法。 本发明使用确定性过程来协调时间提前(TA)命令和定时偏差(TD)测量,使得故障传输或移动终端信号传播变化可以被更快地识别和校正。 通过有效降低时间提前命令的频率,最大限度地减少信令开销,使无线电资源效率最大化。 这通过使用包括连接帧号(CFN)的TA命令信号来指定用于时间提前(TA)调整的特定无线电帧来实现。 在调整物理接收窗口和计算移动终端位置的情况下,不正确地处理定时偏差(TD)测量的可能性被最小化,而没有过多的命令信令要求。
