Claim of US Patent No. 10,342,026

1. An apparatus for transmitting data in a wireless communication system employing time division duplex, the apparatus comprising:a memory, which, in operation, stores a data block, the memory being operated as a circular buffer;
a transmitter, which, in operation, transmits the data block in a plurality of subframes including special subframes, a special subframe containing an uplink portion and a downlink portion separated from each other by a switching portion; and
circuitry, which, in operation, maps the stored data block onto the plurality of subframes using the circular buffer, wherein mapping of bits onto a first special subframe starts from a first position in the circular buffer, mapping of bits onto a second special subframe subsequent to the first special subframe starts from a second position in the circular buffer, and the second position is determined based on the first position.
