Title:
DEEP GENERATIVE MODELS FOR DOWNLINK CHANNEL ESTIMATION IN FDD MASSIVE MIMO SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2022/172198
Kind Code:
A9
Abstract:
Techniques for estimating channel characteristics for a channel between a first device having a plurality of antenna elements and a second device having at least one antenna element. An example method includes the steps of estimating (810) a first set of one or more parameters for the channel, based on training symbols transmitted from the second device to the first device, and estimating (820) a second set of one or more parameters for the channel, based on training symbols or reference signals transmitted from the first device to the second device and based on the first set of one or more parameters.
