Radio Base Station and Method for Transmitting Common Public Radio Interface Data in Radio Base Station

摘要

A method for transmitting Common Public Radio Interface (CPRI) data in a radio base station is provided, which is applicable to the radio base station having at least two CPRI links between a Radio Equipment Control (REC) and a Radio Equipment (RE). The method includes: dividing, by the REC, in-phase/quadrature phase (I/Q) data that needs to be transmitted to the RE into multiple paths of I/Q data with different content, where the multiple paths of I/Q data with different content make up the I/Q data before being divided; transmitting, by the REC, all paths of divided I/Q data to the RE over the at least two CPRI links.

1. A method for transmitting Common Public Radio Interface (CPRI) data in a radio base station with at least two CPRI links between a Radio Equipment Control (REC) and a Radio Equipment (RE), the method comprising:
dividing, by either of the REC and the RE which serve as a peer end of each other, in-phase/quadrature phase (I/Q) data that needs to be transmitted to the peer end into multiple paths of I/Q data with different content; and transmitting, by the peer end, all paths of divided I/Q data to the peer end over the at least two CPRI links, wherein each path of divided I/Q data is transmitted over a different CPRI link.
