METHOD FOR TRACKING AND CONTROLLING BEAM IN WIRELESS COMMUNICATION SYSTEM USING MMWAVE FREQUENCY BAND AND DEVICE THEREOF

摘要

Embodiments of the present invention relate to a method for efficiently transmitting changed tx beam information to a terminal for beam precise correction and beam switching, and performing a stable beam change operation between a base station and a terminal. The present invention provides a control message configuration related to a process of additionally updating base station tx beam-terminal rx beam for beam tracking according to the precise correction of a base station tx beam and a terminal rx beam or mobility of the terminal after completing a base station tx beam selection by using a fixed rx beam of the terminal in a mmWave-based base station/terminal system using a high directivity antenna.;COPYRIGHT KIPO 2017
