A method for measuring and reporting a beam by means of a terminal in a wireless communication system according to an embodiment of the present invention may comprise the steps of: measuring a plurality of transmission beams for a physical downlink control channel (PDCCH) via at least one reception beam; determining at least one transmission beam to be reported to a base station, according to a result of measuring the plurality of transmission beams; and transmitting, to the base station, a measurement report including information relating to the determined at least one transmission beam, wherein the terminal identifies a reception beam applied to each of the determined at least one transmission beam, and reports an index of a synchronization signal block available through the identified reception beam, to the base station via the measurement report. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, the base station or a network.
