1. A communication apparatus comprising:
circuitry, which, in operation, generates a physical layer protocol data unit (PPDU) comprising a signal field and a data field, the signal field comprising a resource unit (RU) allocation field and one or more user specific field and the data field comprising one or more physical layer service data unit (PSDU); and
a transmitter, which, in operation, transmits the generated PPDU, wherein a single PSDU of the one or more PSDU is transmitted over a RU combination, and whether two or more RUs of the RU combination share a single low density parity check (LDPC) tone mapper depends on a total size of the two or more RUs of the RU combination,
wherein the two or more RUs of the RU combination are non-adjacent RUs of RUs arranged in a frequency domain.
