Problems solved by technology

[0010] During the research and practice of the above-mentioned prior art, the inventor found that the downlink user data sent by the first interface unit to the second interface unit is a coded and modulated digital signal. , the data volume of the coded and modulated digital signal is much larger, so there is a problem in the above-mentioned prior art that the data flow between the interface unit of the indoor unit and the outdoor unit is too large, resulting in excessive consumption of line resources

Abstract

Embodiments of the invention relate to a base station technology and disclose a distributed base station. The distributed base station includes an indoor unit and an outdoor unit. The indoor unit includes a transmission layer treatment unit and a first interface unit. The outdoor unit includes a second interface unit, a physical layer treatment unit and a radiofrequency treatment unit. The embodiments in the invention also disclose the indoor unit and outdoor unit of the distributed base station correspondently. The embodiments in the invention can reduce consumption of line resource and can accelerate response speed of the physical layer to holes.

Description

technical field [0001] The invention relates to base station technology, in particular to a distributed base station, an indoor unit and an outdoor unit of the distributed base station. Background technique [0002] The base station is an important part of the mobile communication system. It mainly communicates with other network elements such as the base station controller through the ground interface, and communicates with the user terminal through the air interface. [0003] In the traditional base station, the base station is designed in a cabinet and connected to the antenna through the feeder cable; the loss of the feeder cable is relatively large, which easily leads to waste of resources, and the cabinet-type base station is usually large and heavy, and site selection and installation are difficult. complex. The emergence of distributed base stations can better solve the above problems. Distributed base stations are usually composed of a base band unit (Base Band Uni...
