Title:
METHOD FOR DEMODULATING DATA, AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/228390
Kind Code:
A1
Abstract:
The present application provides a method for data modulation and a communication apparatus. The method comprises: a receiving end device receives indication information sent by a sending end device; the receiving end device determines a layer number k of a current transmission layer according to the indication information, k being an integer greater than or equal to 1; the receiving end device determines a transmission signal of a demodulation reference signal (DMRS) on the first k transmission layers; and the receiving end device demodulates k-th transmission layer data according to the transmission signal of the DMRS on the first k transmission layers. Embodiments of the present application can implement the data modulation performed by the receiving end device according to the DMRS under a condition that the DMRS and the data undergo different channels.
