Abstract: Reduced numbers of encoded bits obtained by encoding input bits by a polar code are incrementally output, for transmission for example. The polar code comprises bit indices for placing bit values before encoding. The bit indices include a first set of bit indices for placing values of the input bits and a second set of bit indices for placing a predetermined bit value. A first reduced number of the encoded bits start from a first starting position, and a second reduced number of the encoded bits start from a second starting position different from the first starting position. The second reduced number of the encoded bits include one or more of the encoded bits not included in the first reduced number of the encoded bits. The reduced numbers of encoded bits may be output from continuous positions, in a circular buffer for example, or may include repeated bits.
