  • Method and apparatus for performing timing synchronization in a wireless communication system
    Patent number: 8310983
    Abstract: 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.

  • Method and apparatus for transporting CDMA traffic over a UMTS-compatible CPRI interface
    Patent number: 7602751
    Abstract: 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.
