Abstract

The present invention discloses radio installation nodes, distributed radio communication base stations comprising the radio installation nodes and a communication method thereof, wherein, the radio installation nodes realize data transmitting to the radio installation control nodes in the adjacent radio base station by using different optical wavelengths. The radio installation nodes are positioned in the area covered by the distributed radio communication base station, the radio installation nodes in the edge of the covered area communicate with the radio installation control nodes of two or more adjacent distributed radio communication base stations, and the radio installation nodes are controlled and managed by the radio installation control nodes of the two or more adjacent distributed radio communication base stations. According to the present invention, communication between the radio installation nodes in a radio communication base station and the radio installation control nodes of the adjacent radio communication base stations is realized.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a radio equipment node, a distributed wireless communication base station and a communication method thereof. Background technique [0002] To improve network coverage, increase system capacity, and reduce costs, wireless operators are gradually adopting distributed base station architectures. Two organizations born in the 3G camp: Common Public Radio Interface (CPRI for short) and Open Base Station Architecture Initiative (OBSAI for short), specialize in the standardization of distributed base station architecture and promote The new generation of base stations is evolving towards distributed. The distributed base station realizes the separation of the baseband part and the radio frequency part, which can share the baseband processing resources of the base station, improve the flexibility of deployment, and reduce the cost of the base station system. [0003] CPRI is a ne...
