1. A terminal apparatus comprising:reception circuitry configured to receive a higher layer message configuring a set of offset values and to receive downlink control information including a field value on a physical downlink control channel, the field value indicating one of the offset values;
determination circuitry configured to select an offset value from the set of offset values, the offset value corresponding to the field value in the downlink control information and to determine a number of modulation coded symbols for channel state information based on the offset value; and
transmission circuitry configured to transmit the channel state information on a physical uplink shared channel.
