METHOD AND APPARATUS FOR CHANNEL ESTIMATION AND DETECTION IN MIMO SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for channel estimation and detection in a multiple-input multiple-output (MIMO) system.SOLUTION: A method includes: generating 10 a demodulation reference signal (DM-RS) pattern for an extended cyclic prefix (CP); and estimating and detecting 20 channel performance on the basis of the generated DM-RS signal pattern. The DM-RS pattern includes rank 5 to 8 patterns supporting 8-layer transmission. The DM-RS pattern also includes a staggered structure.
