Title:
METHOD AND APPARATUS FOR REPORTING CHANNEL STATE INFORMATION IN ADVANCED MIMO ANTENNA SYSTEMS FOR CELLULAR COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2024/096652
Kind Code:
A1
Abstract:
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). Methods for channel state information reporting comprises: receiving information for an analog beam and an R CSI-RS resources; constructing an analog beam codebook; deriving sets of PMIs corresponding to analog beams; identifying a set of digital beams corresponding to each of the analog beams; identifying a set of hybrid beams corresponding to each of the R CSI-RS resources, wherein the set of the hybrid beams comprises the set of digital beams and the analog beam, respectively; identifying a subset of the set of hybrid beams using an index to generate a PMI corresponding to the analog beams; and transmitting a CSI report including the PMI and the subset of the set of hybrid beams.
