Title:
APPARATUS AND METHOD FOR RANDOM ACCESS AND SMALL DATA TRANSMISSION USING CONFIGURED RESOURCES IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/029889
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system is provided. The method includes transmitting, to a base station, a message A of a 2-step random access based on a configured grant small data transmission (CG-SDT) procedure, wherein the message A includes a cell radio network temporary identifier (C-RNTI) medium access control (MAC) control element (CE), and receiving, from the base station, a physical downlink control channel (PDCCH) addressed to the C-RNTI, wherein a random access response reception of the 2-step random access is completed, in case that the CG-SDT procedure is ongoing, a CG-SDT time alignment timer for the CG-SDT procedure is running and the PDCCH includes an uplink grant.
