摘要：
A user device includes a RI generating unit that generates a rank indicator based on a channel condition of a downlink, and a transmitting unit that transmits an uplink signal including the rank indicator to a base station. When the rank indicator is reported to the base station prior to category information of the user device being reported, the RI generating unit generates the rank indicator of a number of bits that has already been known to the user device and the base station.
