Title:
DOPPLER CHANNEL STATE INFORMATION (CSI) BASED ON A MODIFIED SLEPIAN BASIS
Document Type and Number:
WIPO Patent Application WO/2023/206373
Kind Code:
A1
Abstract:
Techniques related to channel measurement and precoding are disclosed. Some aspects of the disclosure relate to devices and methods for receiving a reference signal and generating a phase shift value v Dshift associated with a group of modified Slepian bases based on the reference signal. A channel measurement report sends the phase shift value v Dshift to a network node. The network node employs the phase shift value v Dshift for shifting a phase of Doppler basis as a time domain basis in a precoder for precoding a downlink transmission. Other aspects, embodiments, and features are also claimed and described.
