Title:
通信システムで端末の接続制御方法
Document Type and Number:
Japanese Patent JP7440426
Kind Code:
B2
Abstract:
Provided is a method for controlling the access of a terminal in a communication system. An operation method of a terminal comprises the steps of: receiving, from a base station, configuration information for a two-step random access procedure; transmitting, to the base station, RA MSG-A including an RA preamble and an RA payload, on the basis of the configuration information; and receiving, from the base station, RA MSG-B, which is a response to the RA MSG-A. Therefore, communication system performance can be improved.
