PROBLEM TO BE SOLVED: To provide a terminal device capable of reducing a band occupancy time of a wake-up signal and activating a radio base station accurately.SOLUTION: A terminal device 2 comprises a wake-up signal generation part 231. A hash calculator 2311 of the wake-up signal generation part 231 then calculates a hush value of identification information of a radio base station to output a bit string of n bits. A thinning-out calculator 2312 thins out a bit from the bit string of n bits to output a bit string of p(<n) bits. Coding means 2313 performs BCH coding to the bit string of p bits and outputs the coded bit string as a wake-up ID showing a radio base station that is wished to be woken up. The wake-up ID is then transmitted to the radio base station. |
