Which term describes the signal path from the ground station to the drone?

Explanation:
Sending signals from the ground station up to the drone is called the uplink. In UAS communications, the uplink carries the control commands, flight plans, and other instructions from the operator to the aircraft, setting its actions in flight. The opposite direction, from the drone back to the ground, is the downlink, which carries status and telemetry. The other terms aren’t used for this direction: crosslink usually refers to communication between aircraft or between aircraft and a relay, and interlink isn’t a standard term for this ground-to-air path.
