Abstract: One example discloses an IEEE 802.11 compliant wireless communications device, including: a processor configured to generate a hybrid-physical protocol data unit (hybrid-PPDU) that includes a set of sub-PPDUs; a first sub-PPDU in the set of sub-PPDUs includes a first preamble portion and a first data payload portion; a second sub-PPDU in the set of sub-PPDUs includes a second preamble portion and a second data payload portion; wherein an OFDMA communications signal includes a set of symbol tones divided into a set of resource units (RUs); wherein the processor is configured to map the first sub-PPDU to a first RU within the set of RUs, and map the second sub-PPDU to a second RU within the set of RUs; and wherein the first preamble portion corresponds to a first 802.11 packet format, and the second preamble portion corresponds to a second 802.11 packet format.
