1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
generate an Aggregated Media Access Control (MAC) Protocol Data Unit (AMPDU) payload having an AMPDU payload size associated with a number of bits;
omit pre-Forward Error Correction (FEC) padding of the AMPDU payload at a MAC layer by indicating the AMPDU payload size in a physical layer (PHY)-specific preamble;
generate the PHY-specific preamble comprising the AMPDU payload size without the pre-FEC padding;
calculate a number of Orthogonal Frequency Division Multiplexing (OFDM) symbols for containing the number of bits; and
cause to send the PHY-specific preamble and the number of OFDM symbols to a station device.
