METHOD AND APPARATUS FOR CHANNEL INFORMATION FEEDBACK WITH PRIOR INFORMATION IN MOBILE COMMUNICATIONS

Title:

METHOD AND APPARATUS FOR CHANNEL INFORMATION FEEDBACK WITH PRIOR INFORMATION IN MOBILE COMMUNICATIONS

Document Type and Number:

WIPO Patent Application WO/2023/179579

Kind Code:

A1

Abstract:

Various solutions for channel information feedback with prior information with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a reference signal transmitted by a network side including at least one network node. The apparatus may obtain at least one selected basis. The apparatus may derive a channel response information observed by a receiving domain of the apparatus according to the reference signal. The apparatus may decompose the channel response information into a preferred domain. The apparatus may determine a simplified linear combination coefficient representation of the channel response information in the preferred domain according to the selected basis. The apparatus may report a compressed channel information to the network side based on the simplified linear combination coefficient representation and the preferred domain.
