Application: Base station, method for base station, and computer readable medium (Patent ID: US20240106550A1)

The patent filed by NEC Corp. describes a base station, method, and program designed to enhance throughput in multi-user MIMO by selecting radio terminals for spatial multiplexing and MCS appropriately. The base station includes units for storing correction parameters for each radio terminal, selecting a correction parameter based on spatially multiplexed terminals, calculating correction values, adjusting SINR, and updating correction parameters based on data signal reception success. The method and program outlined in the patent involve similar steps of storing correction parameters, selecting based on spatial multiplexing, calculating correction values, adjusting SINR, and updating correction parameters based on data signal reception outcomes.

The base station's innovative approach involves storing multiple correction parameters for each radio terminal, selecting parameters based on spatial multiplexing combinations, and dynamically adjusting parameters based on data signal reception. By incorporating correction values into SINR estimates and updating parameters based on reception outcomes, the system aims to optimize spatial multiplexing and MCS selection for improved multi-user MIMO throughput. The method and program stored on a computer-readable medium mirror the base station's functionality, offering a comprehensive solution for enhancing performance in multi-user MIMO scenarios through intelligent parameter selection and adjustment based on real-time data signal reception feedback.
