Abstract:
The present invention relates to a method for receiving a reference CSI configuration information and a following CSI configuration information which is configured to report a same RI (Rank Indicator) as the reference CSI configuration information, receiving a first CSI-RS (Channel State Information-Resource Signal) configuration information associated with the reference CSI configuration and a second CSI-RS configuration information associated with the following CSI configuration, number of CSI-RS antenna ports according to the second CSI-RS configuration information is same as number of CSI-RS antenna ports according to the first CSI-RS configuration information; and transmitting CSI determined based on at least one of the first CSI-RS configuration information and the second CSI-RS configuration information.
