Question: What is the primary purpose of providing NTN payload ephemeris information to the gNB?
Option 1: To enable downlink beamforming and enhance signal quality.
Option 2: To facilitate handovers between different NTN Gateways.
Option 3: To support sidelink communication between UEs.
Option 4: To ensure uplink timing and frequency synchronization.
Explanation: The primary purpose of providing NTN payload ephemeris information to the gNB is to ensure accurate uplink timing and frequency synchronization. This information enables the gNB to adjust its transmission parameters to match the NTN's orbital trajectory, ensuring reliable communication between the UE and the network.
