BEAM TRAINING METHOD AND DEVICE IN COMMUNICATION SYSTEM

摘要

The present invention relates to a beam training method and an apparatus in a communication system. A method of a network node for beam training in the communication system comprises the steps of: measuring at least one channel quality factor value indicating channel link performance with a corresponding network node; selecting the beam training scheme based on the measured channel quality factor value; and performing beam training with the corresponding network node by means of the selected beam training method, thereby finding an optimal beam for maintaining services through the most efficient method according to a channel state and minimizing the time consumed for beam training.
