Abstract
This disclosure provides methods, devices and systems for wireless communication, and particularly, for generating or receiving a multi-generation physical layer protocol data unit (PPDU). The multi-generation PPDU may concurrently include a first generation-specific preamble based on a first generation of a wireless communication specification (such as that defined by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards) and a second generation-specific preamble based on a second generation of the wireless communication specification in a same transmission. The generation-specific preambles may be generated based on bandwidth portions of a wireless channel that each generation-specific preamble will occupy in the multi-generation PPDU. One or more of the generation-specific preambles may be modified based on an aggregate bandwidth of the multi-generation PPDU. This disclosure includes several options for modifying one or more generation-specific preambles or data fields to accommodate their use in a multi-generation PPDU.
