Title:
METHOD AND APPARATUS FOR CSI REPORTING BASED ON A CODEBOOK
Document Type and Number:
WIPO Patent Application WO/2022/045804
Kind Code:
A1
Abstract:
The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for operating a user equipment (UE) comprises receiving configuration information about a channel state information (CSI) report based on a codebook, the codebook comprising components, and one of the components being a matrix W
f
comprising a first set of M
v
basis vectors; determining whether W
f
is turned ON or OFF; determining W
f
when W
f
is turned ON; determining remaining codebook components; determining the CSI report based on: the remaining codebook components, when W
f
is turned OFF, and the remaining codebook components and the determined W
f
, when W
f
is turned ON; and transmitting the determined CSI report.
