Disclosed is a fifth generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a fourth generation (4G) communication system such as long term evolution (LTE). The purpose of the disclosure is to detect beam misalignment in a wireless communication system, and a terminal operation method comprises the steps of: receiving multiple reference signals for a first period; receiving multiple reference signals for a second period; and determining whether a beam is misaligned, on the basis of a first measurement value set for the multiple reference signals received for the first period and a second measurement value set for the multiple reference signals received for the second period. The study has been performed under the support of the 'Government-wide Giga KOREA Business' of the Ministry of Science, ICT and Future Planning.

Device and method for detecting beam misalignment in wireless communication system

This disclosure relates to a 5G or pre-5G communication system to support higher data transmission rate than a 4G communication system such as LTE. A method for controlling a terminal in a wireless communication system according to one embodiment of the present invention comprises: a step of performing beam training; and a first determining step of determining whether to stop a trigger for the beam training according to the result of performing the beam training, on the basis of whether or not a beam having a maximum channel gain is changed. This research was carried out with the support of the 'Cross-Ministry Giga Korea Project' of the Korean Government Ministry of Science, ICT and Future Planning.
