[0025] figure 1 The structure of the GSM distributed base station according to the first embodiment of the present invention is shown. The distributed base station in this embodiment includes an antenna 200, a remote radio device 100, and a connection device 300. In this embodiment, the GSM radio remote device 100 and the connection device 300 are connected via Ethernet. The remote radio device 100 is located at the far end, for example, installed on the antenna side, and the connection device 300 is located at the near end, for example, installed in a computer room.

[0026] The remote radio equipment 100 includes a transmission management module 11, a baseband module 12 and a radio frequency module 13.

[0027] Such as Figure 7 As shown, during the sending operation, the connecting device 300 transmits GSM data from the base station controller (not shown) to the transmission management module 11 via Ethernet, and the transmission management module 11 processes the GSM data into...

[0035] figure 2 The structure of the GSM distributed base station according to the second embodiment of the present invention is shown. The remote radio device 100 is located at the far end, for example, installed on the antenna side, and the connection device 300 is located at the near end, for example, installed in a computer room.

[0036] The second embodiment is different from the first embodiment in that, in the second embodiment, the remote radio device 100 is connected to the connection device 300 through a CPRI optical fiber. In this case, the transmission management module 11 in the remote radio equipment 100 includes: a TRE operation manager (TREO&M) 01, a CPRI operation manager (CPRI O&M) 02, and a CPRI interface 03.

[0037] During the sending operation, GSM data from the base station controller passes through the connecting device 300 and then reaches the CPRI interface 03 via the CPRI fiber, and then reaches the CPRI operation manager 02 through the CPRI interface 0...

[0041] image 3 The structure of a multi-standard distributed base station according to the third embodiment of the present invention is shown. The distributed base station of this embodiment is suitable for processing other standard data besides GSM data, such as LTE data and UMTS data. Similar to the first embodiment, in this embodiment, the distributed base station includes an antenna 200, a remote radio device 100, and a connection device 300. The GSM radio remote device 100 and the connecting device 300 are connected via Ethernet. The remote radio device 100 is located at the far end, for example, installed on the antenna side, and the connection device 300 is located at the near end, for example, installed in a computer room. The remote radio equipment 100 includes a transmission management module 11 and a radio frequency module 13.

[0042] The difference from the first embodiment is:

[0043] 1. Because this embodiment is for other standards, there is no need for a baseb...

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 field of mobile communication technology, in particular to a remote radio equipment used in a distributed base station and a distributed base station using the radio remote equipment. Background technique [0002] In the field of mobile communications, distributed base stations have today 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 restricted to the computer room environment. Compared with traditional solutions, network construction costs are greatly reduced, and network deployment time is greatly shortened, which represents a milestone in the development of mobile communication base station technology. At present, distributed base station solutions have been fully introduced in WCDMA, CDMA2000, GSM, TD-SCD...
