Title:
REFERENCE-SIGNAL TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/190361
Kind Code:
A1
Abstract:
The present application provides a reference-signal transmission method and device, used for solving the problem in the prior art of the relatively large resource overhead occupied by a reference signal transmitted in a communications system. The method is: a transmitting device configuring on the first time symbol a set of reference signals having a port, and configuring on each of the time symbols other than said time symbol a reference signal having said port. Thus while it is ensured that a receiving device may obtain the channel parameters of said port, the resource overhead occupied by the reference signal transmitted in a communications system is reduced, thereby improving transmission efficiency of service data.
