| 摘要 |
The invention relates to transmission and reception of clock synchronization data in a wireless communication system. According to the invention a device (12) for 5 transmitting clock synchronization data obtains at least one time reference (TR) of a wireless communication system clock (11), controls transmission of a frequency reference (FR) of the wireless communication system clock (11) via an air interface 10 (17) of the wireless communication system, and provides transmission of the time reference via a transport network (10) associated with the wireless communication system, while the base station (18) receives the frequency reference (FR), locks an own oscillator to 15 the frequency of the frequency reference, receives the time reference (TR) from the transport network (10) and adjusts timing that is controlled by the oscillator based on the time reference. |
