Abstract

The present invention provides a user selection enhancing unit 300, an enhanced scheduling unit 501', a multi-user-multi-input-multi-output, MU-MIMO communication system 500 and a method 100 for enhanced user selection in a multi-user-multi-input- multi-output, MU-MIMO communication system 500, the method comprises the following steps: determining 101 at least one system operating value 302 that indicates the actual systems performance; calculating 102 a number K* of user's equipments, UE, to serve simultaneously in the system on the basis of a signal-to-interference-plus-noise- ratio, SINR, value, wherein the SINR value is determined based on the at least one system operating value 302; and providing 103 the calculated number K* of UEs to serve to a scheduling unit 501, 501' for selectingat least one user S.

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...
