Abstract
The method for feedback of channel quality information in a wireless communication system, according to one embodiment of the present invention, is performed by a terminal and comprises the steps of: receiving feedback configuration information, including information on disjoint segmentation indicating the indexes of channel or beam quality-related parameters for broadcast or multicast services, from a base station; and according to the information on disjoint segmentation in the feedback configuration information, encoding the index of a channel or beam quality-related parameter to be reported and transmitting same to the base station, wherein the disjoint segmentation includes multiple subsets which do not overlap and which have different lengths, and the index of the channel or beam quality-related parameter, which is transmitted to the base station, may indicate a predetermined value in one subset among the multiple subsets.
