Abstract

The present invention discloses how to deploy small cell base stations in the DAS system and how to use the existing DAS system to realize the backhaul transmission method of the indoor small cell base stations. The implementation scheme of the present invention does not affect the wireless access communication in the existing DAS, and does not It is necessary to lay specific cables or optical fibers for the backhaul transmission, and it is not necessary to find a new location to install the small cell base station; thus, the implementation solution of the present invention has low cost and quick deployment.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more particularly, to a small cell base station backhaul transmission method and system based on distributed antennas in the field of wireless communication. Background technique [0002] The concept of small cells has been widely accepted by telecom operators and equipment manufacturers. Usually, multiple small cells can be deployed in a macro cell to form a heterogeneous network. In a heterogeneous network, the small cells will offload the business of the macro cell, thereby increasing the network capacity without adding macro cell sites. Higher cost performance meets the increasing coverage and capacity requirements of mobile networks. [0003] On the other hand, Distributed Antenna System (DAS) is still the main indoor coverage solution. In the DAS indoor coverage system, the downlink wireless signal of the macro base station or macro remote unit (RRH) is broadcast to the a...
