    • Techniques for mitigating temporary loss of synchronization in a wireless communication system are described. In an aspect, a cell may periodically broadcast a mode indicator to indicate synchronous operation or asynchronous operation by the cell. The cell may also broadcast its cell identity (ID), which may omit the mode indicator and would then remain unchanged when the cell switches between asynchronous and synchronous operation. In another aspect, the cell may send system time information indicative of its updated system time when switching from asynchronous operation to synchronous operation. The updated system time may be used for communication with terminals after the switch to synchronous operation. In yet another aspect, the cell may decrease its transmit power prior to switching synchronization mode, switch synchronization mode when its transmit power reaches a predetermined power level, and thereafter increase its transmit power.
    • 描述了用于减轻无线通信系统中的同步暂时丢失的技术。 在一方面,小区可以周期性地广播模式指示符以指示小区的同步操作或异步操作。 小区还可以广播其小区身份(ID),其可以省略模式指示符,并且在小区在异步和同步操作之间切换时将保持不变。 另一方面,当从异步操作切换到同步操作时,小区可以发送指示其更新的系统时间的系统时间信息。 在切换到同步操作之后,更新的系统时间可以用于与终端的通信。 在另一方面,小区可以在切换同步模式之前降低其发射功率,当其发射功率达到预定功率电平时,切换同步模式,然后增加其发射功率。
