Patent ID: 11929821
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 5:
6. A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
identify 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,
receive a first offset for an uplink transmission timing via higher layer signaling,
receive a downlink signal indicating a second offset for the uplink transmission timing, and
transmit 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.
