1. A method of a terminal for transmitting channel state information for one or more beams, the method comprising:
determining whether group-based beam reporting is configured based on channel state information (CSI) reporting configuration information;
measuring reference signal received power (RSRP) for one or more channel state information reference signals (CSI-RS) received through one or more CSI-RS resources; and
transmitting, to a base station, the channel state information including a value in a table configured in advance based on whether the group-based beam reporting is configured and one or more CSI-RS RSRP measurement results obtained by the measurement,
wherein the transmitting of the channel state information to the base station is performed such that in a case that it is determined that the group-based beam reporting is used, the channel state information is transmitted by including a value of 7 bits corresponding to a section in which a CSI-RS RSRP measurement result having a largest value of the CSI-RS RSRP measurement results is included, from the table configured in advance in which values in the range of [−140, -44] dBm are broken down and set at 1 dB intervals, and including remaining CSI-RS RSRP measurement results except for the CSI-RS RSRP measurement result having the largest value of the CSI-RS RSRP measurement results using a table for indicating a differential CSI-RS RSRP measurement result, and
wherein the CSI reporting configuration information includes at least one of a group-based beam reporting parameter indicating whether group-based beam reporting is used and a value indicating a number of the measured CSI-RS resources to be included in the channel state information, and
wherein the determining for whether the group-based beam reporting is configured is performed such that it is determined that the group-based beam reporting is used, in a case that the value indicating the number of the measured CSI-RS resources to be included in channel state information is set as a value exceeding 1.
