1. A communication device, comprising:
a GPS receiver configured to receive a GPS signal from a satellite; and
circuitry configured to:
determine a random number sequence based on
information of a first terminal of a plurality of terminals, and
time information indicating a start time of a slot,
wherein the slot has a specific time length;
determine, based on the received GPS signal and the random number sequence, a common rule between a base station and the plurality of terminals; and
determine, based on the determined common rule between the base station and the plurality of terminals, a wireless resource for downlink communication for each terminal of the plurality of terminals,
wherein the wireless resource is in the slot.
 
10. A communication method, comprising:
receiving a GPS signal from a satellite;
determining a random number sequence based on
information of a terminal of a plurality of terminals, and
time information indicating a start time of a slot,
wherein the slot has a specific time length;
determining, based on the received GPS signal and the random number sequence, a common rule between a base station and the plurality of terminals;
determining, based on the determined common rule between the base station and the plurality of terminals, a wireless resource for downlink communication for each terminal of the plurality of terminals,
wherein the wireless resource is in the slot; and
performing, based on the determined wireless resource, a process corresponding to the downlink communication.
