1. A communication device comprising:
circuitry configured to:
transmit a physical random access channel (PRACH) to a non-terrestrial station device at a time previous to a transmission time allocated to the PRACH, and
receive, from the non-terrestrial station device, information indicating the previous timing,
wherein the circuitry determines the time previous to the transmission time allocated to the MACH based on position information of the communication device and movement trajectory information of the non-terrestrial station device.
