摘要：A method of acquiring Channel State Information (CSI) in a wirelesscommunication system includes transmitting, from a Base Station (BS) to a UserEquipment (UE), a resource setting including time-domain behavior of CSI-ReferenceSignals (RSs) transmission that designates aperiodic, periodic, or semi-persistent; andtransmitting, from the BS to the UE, the CSI-RSs based on the designated aperiodic,periodic, or semi-persistent. The resource setting includes precoding information thatindicates whether precoders applied to the CSI-RSs is the same or different. The resourcesetting includes periodicity and a timing offset value of the CSI-RS transmission when theperiodic or the semi-persistent is designated. The resource setting includes frequency-domain information that designates a wideband or a partial band used for the CSI-RStransmission. The resource setting includes a transmission bandwidth of the CSI-RStransmission when the partial band is designated.
