Claim 0:
1. A method performed by a user equipment (UE) configured to operate in a wireless communication system, the method comprising:
identifying a timing advance (TA) value for transmitting an uplink signal, wherein the TA value is identified based on a first value NTA, a second value NTA,common, and a third value NTA,UE-specific;
receiving a first offset for an uplink transmission timing via higher layer signaling:
receiving a downlink signal indicating a second offset for the uplink transmission timing; and
transmitting the uplink signal based on a timing of the downlink signal, the first offset, the second offset, and the TA value,
wherein the first value NTA is based on one of a random access response or a timing advance medium access control (MAC) control element (CE),
wherein the second value NTA,common is derived from 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.
