Abstract: The present disclosure relates to a technique for radio link monitoring in a wireless communication system, and to operation procedures of the base station and user equipment and a method for radio link quality evaluation on the basis of the technique. In the method, the user equipment divides the downlink channel bandwidth into multiple frequency ranges, measures channel states for each frequency range, and evaluates the radio link quality based on channel state measurement results. Thereafter, the user equipment sends frequency range quality information to the base station, which may then utilize the same for downlink resource allocation. Hence, it is possible to solve the problem of the existing scheme wherein the user equipment enters the physical layer problem detection state or the radio link failure state although a frequency range usable for service provisioning is present within the downlink channel bandwidth.
