Claims21
(canceled)
2:
- A communication device for communicating with a base station, the communication device comprising:
- circuitry configured to:
- receive a system frame number from the base station, the system frame number counting a number of system frames transmitted from the base station continuously with a predetermined interval;
- obtain an extension bit by counting a lapse of the predetermined interval;
- count a number of frames using the system frame number and the extension bit, each of the frames having a longer interval than the predetermined interval;
- and
- receive the frames from the base station.
