1. A method performed by a terminal supporting a narrowband internet of things (NB-IoT) in a wireless communication system, the method comprising:
receiving, from a base station, a system information block (SIB) including first information indicating a report of downlink channel quality;
generating a result of a downlink channel quality measurement performed based on the first information included in the SIB; and
transmitting, to the base station, a radio resource control (RRC) message which is a message 3 (MSG3) of a random access procedure, the RRC message including second information corresponding to the result,
wherein the second information includes information on a minimum NB-IoT physical downlink control channel (NPDCCH) repetition level which satisfies a predetermined block error rate (BLER), and
wherein the second information includes a value indicating that no information is reported for the downlink channel quality measurement.
