Abstract
A terminal capable of performing a random access procedure, the terminal includes a receiver, a controller, and a transmitter. The receiver configured to receive a first signal of the random access procedure from a base station. The controller configured to control a transmission timing at which a second signal of the random access procedure is transmitted according to configuration information associated with a transmission timing. The transmitter configured to transmit, to the base station, the second signal in an unlicensed band at the transmission timing.

A terminal capable of performing a random access procedure, the terminal comprising:
- a receiver configured to receive a first signal of the random access procedure from a base station;
- a controller configured to control a transmission timing at which a second signal of the random access procedure is transmitted according to configuration information associated with a transmission timing;
- and
- a transmitter configured to transmit, to the base station, the second signal in an unlicensed band at the transmission timing.
A base station capable of performing a random access procedure, the base station comprising:
- a transmitter configured to transmit a first signal of the random access procedure to a terminal;
- and
- a receiver configured to receive a second signal of the random access procedure transmitted in an unlicensed band from the terminal at a transmission timing controlled according to configuration information associated with a transmission timing.
A wireless communication system comprising:
- a base station configured to perform a random access procedure;
- and
- a terminal configured to perform the random access procedure, wherein
- the terminal includes:
- a first receiver configured to receive a first signal of the random access procedure from the base station,
- a controller configured to control a transmission timing at which a second signal of the random access procedure is transmitted according to configuration information associated with a transmission timing, and
- a first transmitter configured to transmit, to the base station, the second signal in an unlicensed band at the transmission timing, and
- the base station includes:
- a second transmitter configured to transmit the first signal to the terminal, and
