Title:
METHOD AND APPARATUS FOR TRANSMISSION AND RECEPTION OF CHANNEL STATUS INFORMATION-REFERENCE SIGNAL IN FULL-ORDER MULTI-INPUT MULTI-OUTPUT WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/163797
Kind Code:
A1
Abstract:
The present invention relates to a method and an apparatus for transmitting or receiving a channel status information-reference signal (CSI-RS) in a wireless communication system supporting full-order multi-input multi-output. A method for transmitting a CSI-RS by means of a base station in a wireless communication system according to one aspect of the present invention may comprise: a step of transmitting, to a terminal, information indicating the number M (M≥2) of CSI-RS antenna ports and resource assignment information for each group of CSI-RS resources consisting of an aggregation of K (K≥2) groups; a step of mapping corresponding CSI-RS to the M CSI-RS antenna ports on the CSI-RS resources; and a step of transmitting the mapped CSI-RS to the terminal.
