1. A method for wireless communication by a wireless communication device of a wireless local area network, comprising:
generating a multi-generation physical layer protocol data unit (PPDU) that comprises a first generation-specific preamble formatted based at least in part on a first generation of a wireless communication specification and a second generation-specific preamble formatted based at least in part on a second generation of the wireless communication specification, wherein at least the first generation-specific preamble or the second generation-specific preamble is modified based at least in part on an aggregate bandwidth of the multi-generation PPDU; and
transmitting the multi-generation PPDU via a wireless channel, wherein a first subchannel of the wireless channel comprises the first generation-specific preamble of the multi-generation PPDU and a second subchannel of the wireless channel comprises the second generation-specific preamble of the multi-generation PPDU.
