First channel information is generated based on a first type CSI-RS and a second type CSI-RS, among the at least one first type CSI-RS and the at least one second type CSI-RS. The first channel information is reported by PUCCH-based periodic channel information feedback. If a PDCCH including an indicator is received, second channel information is generated based on the first type CSI-RS and the second type CSI-RS. The second channel information is reported through a PUSCH. The indicator triggers a channel information report associated with the first type CSI-RS and the second type CSI-RS, among the at least one first type CSI-RS and the at least one second type CSI-RS.
