1. A communication device comprising:
circuitry configured to:
receive, from a non-terrestrial station device, information indicating a previous timing,
based on the information indicating a previous timing, 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
wherein the time previous to the PRACH preamble transmission is calculated based on position information of the communication device and/or movement trajectory information.
