Abstract  Abstract

Technology for channel state information (CSI) feedback in a multiple-input multiple-output (MIMO) communication system is disclosed. A method comprises receiving at a mobile device a dynamic channel state information (CSI) feedback switch signal from a transmission station that identifies a selected CSI feedback state for the mobile device. A process for selecting a precoding matrix indicator (PMI) and a rank indicator is identified based on the CSI feedback switch signal as either a process configured for MU-MIMO reception or single-user (SU) MIMO reception of a downlink signal at the mobile device.
