Title:

DOWNLINK DATA TRANSMISSION METHOD, EQUIPMENT, AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2017/067379

Kind Code:

A1

Abstract:

Disclosed are a downlink data transmission method, equipment, and system, used for reducing the data transmission pressure of a data forward transmission interface. The method comprises: first equipment receives, by means of a forward transmission interface, data of a scheduled terminal sent by second equipment, the data of the scheduled terminal being data obtained after the second equipment performs first spatial preprocessing on baseband data of the scheduled terminal; the first equipment performs second spatial preprocessing on the data of the scheduled terminal; and the first equipment converts the data, obtained after second spatial preprocessing, into a radio-frequency signal, and sends the radio-frequency signal.
