Abstract
Methods and apparatuses are provided for transmitting channel information, by a User Equipment (UE). Information for at least one first type Channel Status Information Reference Signal (CSI-RS) and information for at least one second type CSI-RS from an eNB, are identified. First channel information is generated based on a first set of a first type CSI-RS and a second type CSI-RS. Second channel information is generated based on a second set of a first type CSI-RS and a second type CSI-RS. The first channel information is reported by Physical Uplink Control CHannel (PUCCH)-based periodic channel information feedback. The second channel information is reported by the PUCCH-based periodic channel information feedback.
