User terminal and radio communication method

A terminal comprising:

• a receiving section that receives configuration information regarding semi-persistent channel state information (SP-CSI) reporting using an uplink shared channel;
• and
• a control section that, upon detecting a downlink control information (DCI) for deactivation of the SP-CSI reporting, controls to constantly deactivate a single SP-CSI reporting out of one or more SP-CSI reporting corresponding to the configuration information,
• wherein the single SP-CSI reporting corresponds to a value of a CSI request field in the DCI.

A radio communication method for a terminal, comprising:

• receiving configuration information regarding semi-persistent channel state information (SP-CSI) reporting using an uplink shared channel;
• and
• controlling, upon detecting a downlink control information (DCI) for deactivation of the SP-CSI reporting, to constantly deactivate a single SP-CSI reporting out of one or more SP-CSI reporting corresponding to the configuration information,
• wherein the single SP-CSI reporting corresponds to a value of a CSI request field in the DCI.

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

• the base station comprises:
• a transmitting section that transmits configuration information;
• and
• a control section that controls to transmit a downlink control information (DCI), including a CSI request field, for deactivation of the SP-CSI reporting to constantly deactivate a single SP-CSI reporting out of one or more SP-CSI reporting corresponding to the configuration information, and
• the terminal comprises:
• a receiving section that receives the configuration information regarding semi-persistent channel state information (SP-CSI) reporting using an uplink shared channel;
• and
• a control section that, upon detecting the DCI, controls to constantly deactivate the single SP-CSI reporting out of the one or more SP-CSI reporting,
• wherein the single SP-CSI reporting corresponds to a value of the CSI request field in the DCI.
