Abstract: An information processing device (200, 300) includes a first encoding processing unit (212b), a second encoding processing unit (212d), and a communication unit (21, 41). The first encoding processing unit (212b) performs first error correction encoding processing in which a plurality of bit sequences are output from one or more bit sequences. The second encoding processing unit (212d) performs second error correction encoding processing in which one bit sequence is output from one bit sequence. The communication unit (21, 41) transmits at least one of a first transmission signal or a second transmission signal depending on a predetermined condition, the first transmission signal being obtained by performing the first error correction encoding processing and the second error correction encoding processing on transmission data sequences, and the second transmission signal being obtained by performing the second error correction encoding processing on the transmission data sequences.

Abstract: [Object] To provide a wireless link usable in a more stable manner in a situation where beam management is performed. A communication apparatus includes: a control unit that performs control such that a plurality of reference signals associated with pieces of antenna information different from each other is transmitted to a terminal apparatus; and an acquisition unit that acquires control information corresponding to at least any one of the plurality of reference signals from the terminal apparatus after a random access response in a random access procedure is transmitted to the terminal apparatus. The control unit controls following communication with the terminal apparatus on the basis of the antenna information corresponding to the acquired control information.
