  • Patent number: 10973010
    Abstract: A terminal apparatus communicates with a base station apparatus. The terminal apparatus includes: a determination unit that determines the number of modulation symbols for channel state information transmitted on a physical uplink shared channel based on a value of an offset; and a transmission unit that transmits the channel state information to the base station apparatus on the physical uplink shared channel. When two subframe sets are configured by higher layers, the value of the offset is determined depending on the subframe set to which subframes for transmission on the physical uplink shared channel belong. Thus, the communication can be performed efficiently in a radio communication system in which the channel state information is used.
