METHOD AND DEVICE FOR DETERMINING AND APPLYING TIMING ADVANCE IN COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18495349 titled 'METHOD AND DEVICE FOR DETERMINING AND APPLYING TIMING ADVANCE IN COMMUNICATION SYSTEM
Simplified Explanation
The method described in the abstract involves a terminal in a non-terrestrial network (NTN) system receiving system information from a base station, determining the distance between the terminal and the base station, calculating a specific timing advance (TA) offset for the terminal, determining a TA value based on the common TA offset and the specific TA offset, determining the transmission start time point of a preamble based on the TA value, and transmitting the preamble to the base station at the determined time.

Original Abstract Submitted
An example method performed by a terminal in a non-terrestrial network (NTN) system may include receiving, from a base station, system information including position information about the base station and information about a common timing advance (TA) offset; determining the distance between the terminal and the base station based on the position information about the base station and position information about the terminal; determining a specific TA offset for the terminal based on the determined distance; determining a TA value on the basis of the common TA offset and the specific TA offset; determining the transmission start time point of a preamble based on the determined TA value; and transmitting the preamble to the base station based on the determined transmission start time point.
