Title:
METHOD FOR ACCESSING MILLIMETER WAVE CELL IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/052026
Kind Code:
A1
Abstract:
A method for accessing a millimeter wave cell by a terminal in a wireless communication system supporting a millimeter wave (mmWave) according to an embodiment of the present invention comprises the steps of: scanning a plurality of millimeter wave beams sequentially formed in different directions; estimating an ID of a millimeter wave beam to which the terminal belongs, according to the scanning result; and transmitting a random access preamble to a millimeter wave cell, wherein the random access preamble is transmitted through a terminal-specific resource area determined on the basis of the estimated ID of the millimeter wave beam and an identifier of the terminal.
