Method for information transmission between baseband digital processing unit and radio frequency unit

Abstract

The invention provides a method for transferring information between a baseband digital processing unit and a radiofrequency unit. The method comprises the following steps: step 1: transferring the information between the baseband digital processing unit and the radiofrequency unit, wherein the information includes an information describing part containing the information type, the information length and the information content field; the information content field is composed of a plurality of information units, and each unit adopts the Type-Length-Value form to describe; the Type represents the concrete information type carried by the information unit; the Length represents the information content length carried by the information unit; and the Value represents the concrete content carried by the information unit. And Step 2: the baseband digital processing unit or the radiofrequency unit analyzes the received information and analyzes the information according to the information typefield and information length field. By adopting the method, better compatibility can be ensured between the new and the old radiofrequency units and the baseband digital processing unit.

Description

technical field [0001] The invention relates to a message communication method between two devices in the communication field, in particular to a method for information transfer between a baseband digital processing unit and a radio frequency unit. Background technique [0002] The structure of a typical cellular communication system is as follows figure 1 As shown, the user equipment (UE) communicates with the system side equipment through the propagation of wireless signals on the air interface. The system side equipment includes a base station (Node B), a radio network controller (RNC) and a core network equipment (CN). Among them, RNC and Node B form a radio network subsystem (RNS). The Node B can be divided into a baseband digital processing unit (BBU, Base Band Unit) and a radio frequency processing unit (RRU, Radio Remote Unit) according to functions. In the design of a new generation of base stations, Node B increasingly adopts a design in which the baseband digit...
