Problems solved by technology

[0005] There are additional radio frequency channels in this interconnection method, that is, the channel from the output of the power divider to the RXM-OUT, and the channel from the RXD-IN to the processing unit, which increases the difficulty of PCB (Print Circuit Board, printed circuit board) layout, and in addition , additional connectors and external cables increase the cost of the RRU and the difficulty of installation

Embodiment Construction

[0021] An embodiment of the present invention provides an interconnection system of remote radio frequency units RRU, including a baseband unit and at least two remote radio frequency units, and at least one remote radio frequency unit is connected to the baseband unit. The at least two remote radio frequency units are used to receive the main antenna signal and the diversity antenna signal and send them to the baseband unit after direct intermediate frequency processing, and at least one main antenna signal or diversity antenna signal received by the remote radio unit The antenna signal includes a carrier carried by other remote radio frequency units; the baseband unit is configured to process the main antenna signal and diversity antenna signal sent by the remote radio frequency unit after intermediate frequency processing.

[0022] Taking two remote radio units as an example, the interconnection system includes a first remote radio unit 1, a second remote radio unit 2, and a...

Abstract

The embodiment of the invention discloses an interconnected system of a zoom out radio frequency unit and a method, comprising a base band unit and at least two zoom out radio frequency units, wherein at least one zoom out radio frequency unit is connected with the base band unit; the two zoom out radio frequency units are used for receiving the antenna signal of the master set and the antenna signal of the diversity and transmitting to the base band unit after direct medium frequency process; the antenna signal of the master set and the antenna signal of the diversity received by at least a zoom out radio frequency unit include the carrier loaded on the other zoom out radio frequency unit; a base unit is used for processing the antenna signal of the master set and the antenna signal of the diversity after the intermediate frequency processing transmitted by the zoom out radio frequency unit. According to the invention, the simple interconnection of the different zoom out radio frequency units is realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and system for interconnecting remote radio frequency units. Background technique [0002] The current general-purpose RRU (Remote Radio Unit, remote radio unit) carries a fixed number of carriers, which often cannot meet the capacity requirements of dense urban areas. In order to increase the capacity, an RRU interconnection method is proposed in the prior art, and the carrier expansion capacity can be increased through the interconnection of multiple RRUs. [0003] In the prior art solution, the interconnection of multiple RRUs is realized on the radio frequency, specifically adding a main radio frequency output port RXM-OUT and a diversity radio frequency input port RXD-IN on the RRU. Take RRU1 and RRU2 to implement 3 carriers as an example. If one RRU can only carry two carriers, RRU1 handles carrier 1 and carrier 2, and RRU2 handles carrier 3. When t...
