Abstract

A user equipment generates information based on a plurality of values of joint coding of a Rank Index RI and a first Precoding Matrix Index W1 and transmits the information on a physical uplink control channel. The payload size of the information is 5 bits. The first Precoding Matrix Index W1 and a second Precoding Matrix Index W2 correspond to a precoding matrix and 16 values in the plurality of values correspond to the Rank Index RI of 1 or 2 where a part of values in the plurality of values except the 16 values in the plurality of values correspond to the Rank Index RI of more than 2.
