Description

technical field

[0001] This application relates to the technical field of wireless communication. Specifically, the present application describes a method and apparatus for enhancing user selection in a multi-user multiple-input multiple-output (MU-MIMO) communication system. A method and / or system is provided for enhancing a user selection process in MU-MIMO downlink transmission by determining an optimal number of users to serve based on system operating values. The present application can be used in Frequency Division Duplex (FDD) and Time Division Duplex (TDD) systems. Aspects of the present disclosure relate generally to wireless communication systems and, more particularly, to multi-antenna transmission techniques such as configured for MIMO precoding / beamforming. Certain embodiments of the present application relate to user group selection for MU-MIMO downlink transmission. Background technique

[0002] In radio, MIMO communication is a method of using multiple tra...
