Embodiment Construction

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] figure 1 Shows the application scenario of the BBU interconnection of the present invention, in figure 1 Among them, the base station cluster is composed of multiple BBUs placed in the same physical location, and each BBU includes a main control module, a switching module, a baseband processing module BPX, and the like. Each BBU can be connected to its corresponding RRU through an optical port provided on its switching module to form a BBU frame. The ABIS / IUB interfaces of all main control modules are connected to external Ethernet switches to transmit and schedule control...

Abstract

Disclosed are a method and device of data interaction among BBU frames in wireless soft base stations, and the method according to the present disclosure include: respective interconnected optical ports of multiple BBU frames are connected successively to form a BBU ring network; after each BBU frame in the BBU ring network performs forwarding and mapping processing on baseband downlink IQ data from an adjacent BBU frame, the baseband downlink IQ data are mapped to a corresponding logic channel of an optical port of an RRU of the BBU frame so that the RRU of the BBU frame performs downlink processing thereon; after each BBU frame performs forwarding and mapping processing on uplink IQ data of a logic channel of its RRU, the uplink IQ data are mapped to a corresponding logic channel of the interconnected optical port of the BBU frame, and mapped uplink IQ data are transmitted to the adjacent BBU frame for uplink processing.

Description

technical field [0001] The invention relates to the technical field of resource sharing between BBU (Bu¨ding Base band Unit, indoor baseband processing unit) frames of a soft base station in wireless communication, and in particular to a method and device for data interaction between BBU frames in a wireless soft base station. Background technique [0002] After years of development in wireless communication systems, based on remote radio frequency technology, soft base stations supporting multiple standards have become the mainstream of wireless base station development. However, in the existing soft base station layout, the BBU frames are separated from each other, and the baseband resources and processing capabilities in a single isolated BBU in each area are limited. [0003] With the increasing development of today's wireless communication services and the gradual enlargement of data volume, the base station system in a single area is required to handle more and more da...
