Title:
METHOD AND APPARATUS FOR DATA TRANSMISSION IN RRC_INACTIVE
Document Type and Number:
WIPO Patent Application WO/2023/191453
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 receiving a radio resource control (RRC) release message including suspend configuration information and configured grant-small data transmission (CG-SDT) configuration information, starting a timer related to a time alignment (TA) for CG-SDT based on the CG-SDT configuration information, identifying that criteria for a small data transmission (SDT) procedure is met, and in case that any configured grant (CG) occasion corresponding to a synchronization signal block (SSB) with a reference signal received strength (RSRP) above a threshold value is not available while the timer related to the TA for CG-SDT is running, and criteria for a random access-small data transmission (RA-SDT) procedure is met, performing the RA-SDT procedure.
