Methods of transmitting or receiving common public radio interface data at a wireless base station and an associated wireless base station

摘要

A radio base station, comprising a Radio Equipment Control, REC (1101), and a Radio Equipment, RE (1102), at least two Common Public Radio Interface, CPRI links, exist between the REC control ( 1101) and the RE team (1102); and phase / quadrature phase data, I / Q, which need to be transmitted in a divided manner between the REC control (1101) and the RE equipment (1102), are transmitted through the at least two CPRI links, characterized in that that, the REC control (1101) is a REC (1101) that supports multiple modes, a CPRI link exists between a port of the RE equipment (1102) and a port of a module that supports a first mode in the REC control (1101) , there is another CPRI link between the other port of the RE device (1102) and a port of a module that supports a second mode in the REC control (1101), and a data link exists between the module that supports the first mode and the module that supports the second mode; wherein the I / Q data that needs to be transmitted in a divided manner is divided into two I / Q data paths with different content via the REC control or through the RE equipment, a divided I / Q data path is transmitted through the CPRI link between the RE equipment and the module that supports the first mode and the other divided I / Q data path is transmitted between the RE equipment and the module that supports the first mode through the data link between the module that supports the first mode and the module that supports the second mode and the CPRI link between the RE equipment and the module that supports the second mode.
