User terminal and radio communication method

A radio communication method comprising:

• receiving downlink control information (DCI) including information that indicates which code block group (CBG) of a transport block (TB) is present;
• and
• controlling, based on the information, reception or transmission of the CBG using a downlink shared channel or an uplink shared channel that is scheduled by the DCI,
• wherein the DCI includes a field that indicates a common redundancy version between CBGs of the TB, and
• one of 0, 1, 2 and 3 is applied, based on a value of the field, as a redundancy version value.

A base station comprising:

• a transmitter that transmits downlink control information (DCI) including information that indicates which code block group (CBG) of a transport block (TB) is present;
• and
• a processor that controls a scheduling of a downlink shared channel or an uplink shared channel by the DCI, to control reception or transmission of the CBG in a terminal,
• wherein the DCI includes a field that indicates a common redundancy version between CBGs of the TB, and
• one of 0, 1, 2 and 3 is applied, based on a value of the field, as a redundancy version value.

A system comprising a terminal and a base station, wherein:

• the terminal comprises:
• a receiver that receives downlink control information (DCI) including information that indicates which code block group (CBG) of a transport block (TB) is present;
• and
• a first processor that controls, based on the information, reception or transmission of the CBG using a downlink shared channel or an uplink shared channel that is scheduled by the DCI;
• and
• the base station comprises:
• a transmitter that transmits the DCI;
• and
• a second processor that controls a scheduling of the downlink shared channel or the uplink shared channel by the DCI, to control reception or transmission of the CBG in the terminal,
• wherein the DCI includes a field that indicates a common redundancy version between CBGs of the TB, and
• one of 0, 1, 2 and 3 is applied, based on a value of the field, as a redundancy version value.
