8 Claims

1. A method performed by a user equipment (UE) in a non-terrestrial network (NTN), the method comprising:

receiving, from a base station via a satellite, first information associated with a first timing advance (TA) common for a cell;

determining a second TA based on a position of the UE;

performing, based on the first TA and the second TA, uplink transmission to the base station;

receiving, from the base station via the satellite, second information on a threshold for a channel quality indicator (CQI) report disabling mechanism; and

determining whether the CQI report is disabled or not based on a comparison between the threshold and a measured propagation delay between the UE and the satellite.
