1. A communication apparatus, comprising:
a transmitter, which, in operation, transmits a trigger frame comprising a user field that contains an association identifier 12 (AID12) subfield and a signaling indicating multiple resource units (RUs); and
a receiver, which, in operation, receives, from a station identified by the AID12 subfield, a trigger based (TB) physical layer protocol data unit (PPDU) transmitted using the multiple RUs,
wherein if first multiple contiguous RUs are as large as a single RU and fit into the single RU in a frequency domain, the first multiple contiguous RUs are not allocated to a station.
