1. A method for wireless communication by an access point (AP) of a wireless local area network (WLAN), comprising:
obtaining first data for a first wireless station;
obtaining second data for a second wireless station; and
transmitting a wireless packet that includes a physical layer protocol data unit comprising both a first generation-specific preamble formatted according to a first generation of a wireless communication protocol via a first subchannel of a wireless channel and a second generation-specific preamble formatted according to a second generation of the wireless communication protocol via a second subchannel of the wireless channel, the physical layer protocol data unit further comprising the first data and the second data populated in respective portions of one or more data fields after both the first generation-specific preamble and the second generation-specific preamble, the first generation-specific preamble indicating a first resource unit (RU) allocation in the one or more data fields in accordance with the first generation of the wireless communication protocol and the second generation-specific preamble indicating a second RU allocation in the one or more data fields in accordance with the second generation of the wireless communication protocol, the second RU allocation allocating at least one RU within the first subchannel for the second data corresponding to the second generation of the wireless communication protocol.
