- satellite communication due to a Satellites can cover a large area of the ground, and satellites can orbit the earth, so theoretically every corner of the earth can be covered by satellite communications.
- satellite communication has great social value.
- Satellite communication can be covered at a lower cost in remote mountainous areas, poor and backward countries or regions, so that people in these regions can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed regions and promoting development of these areas.
- the distance of satellite communication is long, and the cost of communication does not increase significantly with the increase of communication distance; finally, the stability of satellite communication is high, and it is not limited by natural disasters.

- the UE In the NTN system (such as NR-NTN system or Internet of Things NTN (Internet of Things NTN, IoT-NTN) system), like the NR system, UE needs to consider the impact of timing advance (Timing Advance, TA) when performing uplink transmission . Since the propagation delay in the system is relatively large, the range of the TA value is also relatively large.
- TA Timing Advance
- the UE When the UE is scheduled to perform uplink transmission in time unit (such as time slot or subframe) n, the UE considers the round-trip propagation delay and transmits in advance during uplink transmission, so that the uplink transmission on the network device side can be realized when the signal arrives at the network device side time unit n.

- Case 1 As shown in FIG. 2 , the downlink (downlink, DL) time unit and the uplink (uplink, UL) time unit on the network device side are aligned. Correspondingly, in order to make the uplink transmission of the UE arrive at the network device side aligned with the uplink time unit of the network device side, the UE needs to use a larger TA value. In some cases, the TA value corresponds to an offset value Koffset.
- Case 2 is shown in FIG. 3 , there is an offset value between the downlink time unit and the uplink time unit on the network device side.
- the UE if the uplink transmission of the UE is to be aligned with the uplink time unit of the network device when it arrives at the network device side, the UE only needs to use a smaller TA value.
