Distributed resource unit signaling

A wireless communication device comprising:

• one or more memories that store processor-executable code;
• and
• one or more processors coupled with the one or more memories and configured to, in association with executing the code, cause the wireless communication device to:
• receive a trigger frame soliciting a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU) from the wireless communication device, the trigger frame comprising a user information field indicating a resource unit (RU) allocation and a distributed transmission bit indicating a tone distribution information, the tone distribution information indicating whether a number of tones are allocated for a contiguous transmission or a distributed transmission;
• and
• transmit the TB PPDU over a wireless channel based on a mapping of the number of tones to subcarrier indices associated with the wireless channel according to a first tone plan or a second tone plan based on whether the number of tones are allocated for the contiguous transmission or the distributed transmission, respectively.

A method for wireless communication performed by a wireless communication device, comprising:

• receiving a physical layer convergence protocol (PLCP) protocol data unit (PPDU) having a physical layer preamble followed by a data payload, the physical layer preamble carrying bandwidth information indicating a bandwidth of a wireless channel associated with the PPDU and carrying distributed signaling information indicating whether the PPDU is transmitted as a contiguous transmission or a distributed transmission;
• demapping the PPDU from a number of subcarrier indices associated with the wireless channel according to a first tone plan or a second tone plan based on whether the PPDU is transmitted as the contiguous transmission or the distributed transmission, respectively, wherein the distributed signaling information comprises a bitmap, each bit of the bitmap indicating whether a respective subchannel of the wireless channel is associated with contiguous transmissions or distributed transmissions;
• and
• recovering the data payload based at least in part on demapping the PPDU.
