METHOD AND APPARATUS FOR ACQUIRING CHANNEL STATE INFORMATION IN ANTENNA ARRAY

摘要

A method for transmitting channel state information by a terminal comprises the step of: receiving relation information on a CSI-RS and a physical antenna from a base station by the terminal, the relation information including information on a first CSI-RS and a first physical antenna transmitting the first CSI-RS and information on a second CSI-RS and a second physical antenna transmitting the second CSI-RS; and transmitting first channel state information and second channel state information to the base station on the basis of the relation information by the terminal

1. A method for transmitting channel state information by a terminal, the method comprising:
receiving, by the terminal, relation information related to a CSI-RS and a physical antenna from a base station, the relation information including information on a first CSI-RS and a first physical antenna transmitting the first CSI-RS and information on a second CSI-RS and a second physical antenna transmitting the second CSI-RS; and transmitting, by the terminal, first channel state information and second channel state information to the base station based on the relation information, wherein the first physical antenna and the second physical antenna are included in one antenna array, wherein the first channel state information is information related to a channel state between the terminal and the first physical antenna determined based on the first CSI-RS, and wherein the second channel state information is information related to a channel state between the terminal and the second physical antenna determined based on the second CSI-RS.
