摘要： A base station has a processor to generate a Code Division Multiple Access (“CDMA”) data frame. The CDMA data frame comprises a plurality of Basic Frames. At least one of the plurality of Basic Frames comprises a vendor-specific field. A modem transports the CDMA data frame over a Universal Mobile Telecommunications System (“UMTS”)-compatible link between the base station and a remote head having a transceiver.

摘要： A method and apparatus for performing time synchronization is provided. The method/apparatus includes, at a radio subsystem: receiving, from a digital subsystem, a first signal via the link, where the link not dedicated to timing synchronization; determining a time difference between the first signal and a second signal; converting the time difference to a time error, sending, via the link, the time error or time difference to the digital subsystem. The method further includes, at the digital subsystem, inputting the time error, received from the radio subsystem, to a phased locked loop (PLL) in order to adjust an oscillator frequency so as to reduce the amount of the time error and thus synchronizing the radio access network with the second signal received at the radio subsystem, without the need for an additional connection between the digital and radio subsystems.
摘要翻译：提供了一种用于执行时间同步的方法和装置。所述方法/装置包括：在无线电子系统处：经由所述链路从数字子系统接收第一信号，其中所述链路不专用于定时同步; 确定第一信号和第二信号之间的时间差; 将时差转换为时间误差，经由链路将时间误差或时差发送到数字子系统。该方法还包括在数字子系统中将从无线电子系统接收的时间误差输入到锁相环（PLL），以便调整振荡器频率，以便减少时间误差量，从而同步无线电接入网络，具有在无线电子系统处接收的第二信号，而不需要数字和无线电子系统之间的附加连接。
