Title: BEAM TRANSMISSION-RECEPTION METHOD, BASE STATION, TERMINAL, AND WIRELESS COMMUNICATION SYSTEM
Abstract:
A beam transmission-reception method executed in a wireless communication system in which a terminal communicates with a base station using a beam has a step of receiving, at the base station, a random access signal transmitted as a connection request from the terminal, the step comprising grouping a plurality of beam directions by combining a main beam direction determined to be appropriate for receiving the random access signal with one or more beam directions adjacent to the main beam direction, and receiving the random access signal using the grouped plurality of beam directions.
