Title:
A method and a device which transmit and receive the feedback information in a communications system
Document Type and Number:
Japanese Patent JP5969037
Kind Code:
B2
Abstract:
A method and apparatus for transmitting feedback information by a User Equipment (UE) in a mobile communication system are provided. The method includes receiving information about at least one Channel State Information Reference Signal (CSI-RS); performing channel estimation based on the information about at least one CSI-RS; receiving information about at least one feedback; and transmitting at least one feedback including a channel estimation result using the information about at least one feedback, wherein the information about at least one feedback includes information about a transmission timing and a feedback mode for at least one feedback.
