1. A radio base station comprising:
- an acquiring unit which acquires a pilot signal that is discretely included in a transmission signal to be transmitted from a mobile terminal and is referenced to adjust a transmission timing of the transmission signal in the mobile terminal;
an adjusting unit which adjusts the transmission timing of the transmission signal in the mobile terminal based on the pilot signal; and
a changing unit which changes an adjustment period in which the transmission timing is adjusted by the adjusting unit based on a transmission cycle of the pilot signal.

13. A communication method performed by a radio base station which communicates with a mobile terminal, the communication method comprising:
-
acquiring a pilot signal which is discretely included in a transmission signal to be transmitted from the mobile terminal and is reference to adjust a transmission timing of the transmission signal in the mobile terminal; adjusting the transmission timing of the transmission signal in the mobile terminal based on the pilot signal; and changing the adjustment period in which the transmission timing is adjusted in the adjusting operation based on a transmission cycle of the pilot signal.
