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

Claim 14:
15. A base station configured to operate in a wireless communication system, the base station comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
identify 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,
transmit a first offset for an uplink transmission timing via higher layer signaling,
transmit a downlink signal indicating a second offset for the uplink transmission timing, and
receive 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.
