Title:

DIGITAL FRONTHAUL DATA TRANSMISSION METHOD, DEVICE AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2017/024529

Kind Code:

A1

Abstract:

The invention relates to the field of communications. Disclosed are a digital fronthaul data transmission method, device and system capable of improving system performance of a distributed base station. Specifically, the solution comprises: receiving, by a first microwave equipment, digital fronthaul data, and acquiring from the digital fronthaul data general information and radio signal information therein; performing digital OAM on the general information to acquire I/Q data thereof; performing time division multiplexing on the radio signal information and the I/Q data of the general information to generate a microwave air frame; encapsulating the radio signal information and the I/Q data of the general information in a payload region of the microwave air frame, and arranging a pilot region in a microwave overhead and the payload region in an alternating manner at a predetermined interval; and transmitting the microwave air frame. The invention is used in a digital fronthaul data transmission process.
