METHODS OF GENERATING CHANNEL STATE INFORMATION (CSI) AND USER EQUIPMENT (UE) IN WIRELESS COMMUNICATION SYSTEM Russian patent published in 2025 - IPC H04B7/02 H04W72/02 

FIELD: wireless communication.

SUBSTANCE: invention relates to wireless communication and more specifically to devices and methods for generating channel state information (CSI). From a base station of a wireless communication system, a set of reference signals CSI-RS is transmitted, wherein the set of CSI-RS comprises two or more sets of CSI-RS, and on the user device in the wireless communication system, selecting a predetermined number of CSI-RSs from the CSI-RS sets received from the base station, and generating the CSI based on the selected CSI-RS, wherein the CSI contains, for each of the selected CSI-RS, corresponding parameters, including the CSI-RS identifier.

EFFECT: providing flexible CSI generation and signalling in the context of hybrid downlink beamforming, with support for transmitting multiple CSI-RS sets (including using substantially different spatial beams) to user device(s) and support of possibility of one-time communication from user device to base station by means of CSI about several CSI-RS (including about CSI-RS from different sets of CSI-RS), which, in turn, provides more flexible scheduling of resources for downlink transmission on the side of the base station.
