Abstract

The invention provides radio frequency remote equipment and a distributed base station. In the distributed base station, while sending an operation, the radio frequency remote equipment receives first standard data and processes the first standard data into first transmission data, the first transmission data is subjected to base band processing to obtain second transmission data, and then the second transmission data is subjected to radio frequency processing to obtain an antenna signal; and while receiving the operation, the ratio frequency remote equipment carries out reverse radio frequency processing on the antenna signal received by an antenna to obtain the second transmission data, the obtained second transmission data is subjected to the reverse base band processing to obtain the first transmission data; and the first transmission data obtained by the reverse base band processing is processed into the first standard data.

Description

technical field

[0001] The present invention relates to the technical field of mobile communication, in particular to a remote radio equipment used in a distributed base station and a distributed base station using the remote radio equipment. Background technique

[0002] In the field of mobile communications, distributed base stations have become a key consideration for mobile operators worldwide in deploying mobile networks. The remote radio unit (RRH, RadioRemote Unit) is connected to the baseband unit (BBU, Base Band Unit) through optical fiber. , so that the radio frequency unit is no longer limited by the environment of the computer room. Compared with traditional solutions, the cost of network construction is greatly reduced, while the time for network deployment is greatly shortened, representing a milestone in the development of mobile communication base station technology. At present, distributed base station solutions have been fully introduced in WCDMA, CDMA2000...
