Abstract
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.

A method for transmitting Common Public Radio Interface (CPRI) data in a radio base station over CPRI links between a Radio Equipment Control (REC) and a Radio Equipment (RE), the method comprising:
- dividing, a single in-phase/quadrature phase (I/Q) data stream into multiple paths of I/Q data each of which carrying different content of the single I/Q data stream, wherein the REC and the RE serve as peer ends to one another, and wherein the multiple paths of I/Q data include at least a first path of I/Q data and a second path of I/Q data, the first path of I/Q data having different content than the second path of I/Q data;
- and
- transmitting, by a first one of the peer ends, the multiple paths of I/Q data to a second one of the peer ends over at least two CPRI links, wherein each path in the multiple paths of I/Q data is transmitted over a different one of the at least two CPRI links, wherein the REC supports multiple modes, wherein the at least two CPRI links include a first CPRI link extending between the RE and a first module supporting a first mode in the REC, and a second CPRI link extending between the RE and a second module supporting a second mode in the REC, the second mode being different than the first mode, and wherein a data link extends between the first module and the second module, and
- wherein transmitting the multiple paths of I/Q data to the second peer end over the at least two CPRI links comprises transmitting, by the RE, the first path of I/Q data to the first module in the REC over the first CPRI link, and transmitting the second path of I/Q data to the second module, wherein the second module transmits the second path of I/Q data to the first module over the data link.
