Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message that indicates terrestrial network (TN) mapping information that is associated with an artificial intelligence (AI) and/or machine learning (ML) model.

Abstract: Example embodiments of the present disclosure relate to timing adjustment for uplink transmission, particularly in a high-speed scenario. A first device receives, from a second device, offset information indicating a difference in propagation delays between the first device and a third device experienced by the second device.

The time shifting value is associated with a switch from a beam associated with the first device to a beam associated with the third device. The third device is different from the first device. The first device transmits, to the second device, timing information indicating an amount of timing advance for transmission from the second device to the third device. The timing information is determined based on the time shifting value. Through this solution. UL transmission will be timing aligned.
