1. A reception apparatus, comprising:
a receiver, which, in operation, receives an aggregate physical layer convergence protocol data unit (A-PPDU) including a first PPDU and a second PPDU, the first PPDU including a first portion and a second portion, wherein
the first portion of the first PPDU is duplicated in a frequency axis direction and transmitted on a primary channel and a secondary channel, each of the primary channel and the secondary channel having a standard channel bandwidth,
the second portion of the first PPDU is transmitted using a variable channel bandwidth that is N times the standard channel bandwidth, where N is an integer of 2 or greater,
the second PPDU includes a non-legacy header field and a data field, the second PPDU being transmitted using the variable channel bandwidth; and
a reception processor, which is coupled to the receiver and which, in operation, performs a reception process on the received A-PPDU, wherein in a case where the received A-PPDU is transmitted by a single carrier, the second PPDU includes N repetitions of data blocks, which consist of original data blocks and N−1 duplications of the original data blocks, in the non-legacy header field.
