Abstract
A method in which a base station transmits a CSI (channel state information)-RS (reference signal) in a MIMO (multiple input multiple output) antenna system is provided. The base station periodically transmits a CSI-RS for first CSI to a terminal. The base station requests the terminal to transmit second CSI in a first subframe. When a CSI-RS occasion is configured, the base station transmits a CSI-RS for the second CSI to the terminal for a duration of the CSI-RS occasion from a second subframe or to the second subframe, which is a subframe after a first offset configured for CSI-RS transmission from the first subframe.
