Classification: CPC H | IPC H

Claim 10:
11. A method performed by a base station configured to operate in a wireless communication system, the method comprising:
identifying a timing advance (TA) value for receiving an uplink signal from a user equipment (UE), wherein the TA value is based on a first value NTA, a second value NTA.common, and a third value NTA.UE-specific;
transmitting a first offset for an uplink transmission timing via higher layer signaling;
transmitting a downlink signal indicating a second offset for the uplink transmission timing; and
receiving the uplink signal associated with the uplink transmission timing, wherein the uplink transmission timing is based on a timing of the downlink signal, the first offset, the second offset, and the TA value,
wherein the first value NTA is associated with a random access response or a timing advance medium access control (MAC) control element (CE),
wherein the second value NTA,common is associated with higher layer parameters, and
wherein the third value NTA,uE-specific is obtained by the UE based on a position of the UE and information on a position of a satellite wirelessly connected to the UE.
