FIELD: radio engineering, communication.
SUBSTANCE: invention discloses a method for receiving configuration information of the supporting CSI and configuration information of the next CSI, which is configured to transmit the same RI (rank indicator) as configuration information of the supporting CSI, receiving information about the restrictions of the precoding codebook subset for the supporting CSI process and the next CSI process. The RI set (rank indicator) of the next CSI process is configured the same as the last reported RI of the supporting CSI process, the RI set, limited by restricting the codebook subset for the next CSI process, is the same as the RI set limited by restricting the codebook subset for the supporting CSI process, and is transmitted to the CSI, based on, at least, one of the restrictions of the codebook subset.
EFFECT: more effective transmitting the information about the channel state.
