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 processing Common Public Radio Interface (CPRI) data in a radio base station with a plurality of CPRI links between a Radio Equipment Control (REC) and a Radio Equipment (RE), wherein the REC is an REC that supports multiple modes, wherein a first CPRI link exists between a first port of the RE and a port of a module supporting a first mode in the REC, wherein a second CPRI link exists between a second port of the RE and a port of a module supporting a second mode in the REC, and wherein a data link exists between the module supporting the first mode and the module supporting the second mode, the method comprising:
receiving, by a first peer end, multiple paths of I/Q data with different content transmitted by a second peer end, over the first CPRI link and the second CPRI link, wherein the multiple paths of I/Q data make up a set of I/Q data that needed to be transmitted by the second peer end to the first peer end in a divided manner; and combining, by the first peer end, the multiple paths of I/Q data into the set of I/Q data that needed to be transmitted by the second peer end to the first peer end in a divided manner; wherein the RE is the first peer end and the REC is the second peer end, or the REC is the first peer end and the RE is the second peer end.
