Title:
METHOD AND APPARATUS FOR PERFORMING CONFIGURED GRANT BASED SMALL DATA TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/106669
Kind Code:
A1
Abstract:
The present disclosure relates to a method for performing a configured grant (CG) based small data transmission (SDT) in a wireless communication system. In particular, the method includes the steps of: storing a reference Reference Signal Received Power (RSRP) upon a reception of Configured Grant based Small Data Transmission (CG-SDT) configuration via a Radio Resource Control (RRC) release message; measuring a current RSRP based on a SDT procedure being initiated; and based on a difference between the current RSRP and the reference RSRP being less than or equal to a threshold value, perform a CG-SDT procedure based on the CG-SDT configuration.
