Terminal apparatus, base station apparatus, integrated circuit, and radio communication method

A base station apparatus comprising:

• transmission circuitry configured to transmit a higher layer message configuring a set of values and transmits downlink control information on a physical downlink control channel;
• and
• reception circuitry configured to receive channel state information on a physical uplink shared channel, wherein
• an offset value is determined from the set of values based on a field value in the downlink control information, and
• a number of modulation coded symbols for the channel state information is determined based on the offset value.

A communication method for a terminal apparatus, comprising:
