Title:
MULTI-USER DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/014556
Kind Code:
A1
Abstract:
The present application discloses a multi-user data transmission method, comprising: by a target UE, receiving a CSI-RS configuration signaling from a base station and correspondingly measuring and reporting CSI information; by said target UE, receiving a scheduling signaling from the base station and correspondingly receiving a downlink data; and by said target UE, decoding, according to acquired control information of each interfering UE of a plurality of UEs other than said target UE, data of said each interfering UE, and decoding the downlink data of said target UE according to the decoding result of said each interfering UE. With the method of the present invention, the data transmission of multi-user multiplexing based on power domain can be effectively supported, and the system performance can be optimized.
