  • This abstract for appeared for patent application number 18191447 Titled 'METHOD AND APPARATUS FOR DATA TRANSMISSION IN RRC_INACTIVE'

Simplified Explanation

This abstract describes a method used by a terminal in a wireless communication system to support high data transmission rates in a 5G or 6G network. The method involves receiving a message that includes information about suspending the system and configuring small data transmission. The terminal then starts a timer for time alignment based on the small data transmission configuration. If certain criteria for a small data transmission procedure are met and a configured grant occasion is not available, the terminal performs a random access-small data transmission procedure.


Original Abstract Submitted

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.
