Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] The core of the present invention is to use the IQ data area in the basic frame of CPRI to construct a transmission container, form the sampling cell with the IQ data to be transmitted and the type field representing the IQ data system mode, and fill the transmission container in sequence according to the sampling sequence , after a transmission container is filled, it is sent out by the CPRI interface. If no new sampling cells are generated within the time corresponding to the transmission container, invalid cells may be filled and sent out. The receiving end sequentially receives and extracts the sample cells in the transmission container, obtains the corresponding system mode according to the value of the type field in the sample cell, and processes the ...

Abstract

The utility model relates to the communication field, disclosing a method and a system to transmit wireless business data through a common public radio interface (CPRI), enabling the IQ data of the different system modes to be transmitted by a CPRI frame. The utility model is characterized in that an IQ data area of a CPRI base frame is constructed as a transmission container, the transmitting IQ data and the type field for the IQ data of the system mode form a sampling signal unit, which are sent after being filled in the transmitting container based on the sampling order. The sampling signal unit is extracted in order from the transmitting container by a receiving end, and the timing information of the IQ data system mode in the sampling signal unit is resumed based on the value of the type field, and the subsequent process of the IQ data is finished. The basic information comprises the corresponding relationship of the style field value and the IQ data system mode, the frame number constructing the CPRI basic frame of the transmitting container and the IQ data bit of the different system modes.

Description

technical field [0001] The present invention relates to the communication field, in particular to the Common Public Radio Interface (CPRI for short) technology. Background technique [0002] CPRI is a specification about the key interface inside the mobile communication wireless base station that is publicly published by a number of companies in cooperation with the industry. The CPRI specification is a public specification on this key interface in the industry, providing a set of common standards for key internal interfaces of base stations. The CPRI is responsible for defining the key internal interface of the wireless base station between a radio equipment controller (Radio Equipment Controller, "REC" for short) and a radio equipment (Radio Equipment, "RE" for short). The goal of the standard is to create an open market for cellular base stations, thereby substantially reducing the large development effort and expensive costs that have long accompanied base station desig...
