Title:
METHOD AND APPARATUS FOR MULTIPLEXING AND OMITTING CHANNEL STATE INFORMATION
Document Type and Number:
WIPO Patent Application WO/2020/184971
Kind Code:
A1
Abstract:
The present 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 present 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 UE for CSI reporting in a wireless communication system is provided. The method comprises receiving, from a BS, configuration information for a CSI report, the CSI report comprising a first CSI part and a second CSI part, the second CSI part including a total of K
NZ non-zero coefficients across v layers, determining a priority value for each of the total of K
NZ non-zero coefficients, partitioning the second CSI part into Group 0, Group 1, and Group 2 such that, based on the determined priority values of the total of K
NZ non-zero coefficients, indicators to non-zero coefficients having higher priority values are included in Group 1 and indicators to non-zero coefficients having lower priority values are included in Group 2, and transmitting, to the BS over an uplink (UL) channel, UL control information (UCI) including Group 0 or (Group 0, Group 1) or (Group 0, Group 1, Group 2) of the second CSI part.
