Communication device, communication method, and program for selectively switching between a first physical uplink channel and a second physical uplink channel

A communication device configured to operate as a base station by using a New Radio (NR);

• and comprising:
• communication circuitry configured to perform wireless communication with a terminal device and to receive a first Physical Uplink Control CHannel (PUCCH) or a second PUCCH transmitted by the terminal device,
• control circuitry configured to selectively switch between the first PUCCH and the second PUCCH in accordance with a type of PUCCH carried information, each of the first PUCCH and the second PUCCH being configured to receive control information from the terminal device,
• wherein a sub carrier spacing and a symbol length in a slot are changeable in the NR, and
• wherein a number of first symbols of the first PUCCH are different from a number of second symbols of the second PUCCH, the first PUCCH and the second PUCCH being allocated during the slot to receive control information from the terminal device.

A communication method performed by a communications device, the method comprising:

• performing wireless communication with a base station by using a New Radio (NR);
• and
• selectively switching between a first Physical Uplink Control CHannel (PUCCH) and a second PUCCH in accordance with a type of PUCCH carried information, each of the first PUCCH and the second PUCCH being configured to transmit control information from the communication device to the base station,
• wherein a sub carrier spacing and a symbol length in a slot are changeable in the NR, and
• wherein a number of first symbols of the first PUCCH are different from a number of second symbols of the second PUCCH, the first PUCCH and the second PUCCH being allocated during the slot to transmit control information to the base station.
