Classification: CPC H  Y | IPC H

Claim 9:
10. The base station operating in a wireless communication system, the base station comprising:
at least one transceiver for transmitting and receiving a wireless signal; and
at least one processor for controlling the at least one transceiver,
wherein the at least one processor configured to:
transmit, to a terminal, configuration information related to channel state information (CSI) reporting;
transmit, to the terminal, a CSI-reference signal (CSI-RS) on a CSI-RS resource set; and
receive, from the terminal, the CSI generated using the CSI-RS,
wherein the CSI-RS resource set is configured with N (N is a natural number) resource pairs,
wherein each of the N resource pairs includes one resource of each of the two resource groups,
wherein each of the N resource pairs is associated with one CSI-RS resource indicator (CRI) value,
wherein the CSI includes i) one of N CRI values associated with the N resource pairs and ii) X (X is a natural number) CRI values other than the N CRI values based on the X being configured by the configuration information, and
wherein each of the X CRI values corresponds to a single resource of the CSI-RS resource set.
