FIELD: physics.
SUBSTANCE: invention relates to wireless communication. Transmission device includes a transmission signal generator, which, during operation, generates a transmission signal having an aggregated PPDU, which includes a legacy preamble, a legacy header, a non-inherited preamble, a plurality of non-inherited headers and a plurality of data fields; and a transmitter which, during operation, transmits the generated transmission signal, wherein the legacy preamble, the inherited header and the plurality of non-inherited headers are transmitted using the standard bandwidth, while the non-inherited preamble and a plurality of data fields are transmitted using a variable bandwidth, which is greater than the standard bandwidth, and multiple sets of non-inherited header and corresponding data field are transmitted in series in the time domain.
EFFECT: invention is intended for transfer of aggregated protocol data unit of physical level (aggregated PPDU).
