TRANSMISSION DEVICE AND METHOD FOR TRANSFER OF AN AGGREGATED PROTOCOL UNIT OF PHYSICAL LEVEL DATA

摘要

A transmission apparatus of the present disclosure includes a transmission signal generator which, in operation, generates a transmission signal having an aggregate Physical layer Protocol Data Unit (aggregate PPDU) that includes a legacy preamble, a legacy header, a non-legacy preamble, a plurality of non-legacy headers and a plurality of data fields; and a transmitter which, in operation, transmits the generated transmission signal, wherein the legacy preamble, the legacy header and the plurality of non-legacy headers are transmitted using a standard bandwidth, while the non-legacy preamble and the plurality of data fields are transmitted using a variable bandwidth that is larger than the standard bandwidth and wherein a plurality of sets of a non-legacy header and a corresponding data field are transmitted sequentially in a time domain.
