`
`Asserted Claims
`
`Claim 1
`A method of constructing a frame structure for data transmission, the method comprising:
`generating a first section comprising data configured in a first format compatible with a first communication system using symbols;
`generating a second section following the first section,
`the second section comprising data configured in a second format compatible with a second communication system using symbols,
`wherein the first communication system's symbols and the second communication system's symbols co-exist in one transmission
`scheme and
`wherein: the second format is compatible with the second communication system configured to support higher mobility than the first
`communication system,
`wherein each symbol in the second communication system has a shorter symbol period than that in the first communication system;
`generating at least one non-data section containing information describing an aspect of data in at least one of the first section and the
`second section; and
`combining the first section, the second section and the at least one non-data section to form the frame structure.
`
`Claim 3
`The method of claim 1, wherein the non-data section comprises at least one of a preamble, a frame control header (FCH), a burst, and
`a map of at least one of the first section and the second section.
`
`Claim 4
`The method of claim 3, wherein the second section follows the first section in at least one of time sequence and frequency spectrum.
`
`Claim 6
`The method of claim 1, wherein each of the first section and the second section carries at least one of uplink and downlink data.

`wherein the first communication system's symbols and the second communication system's symbols co-exist in one transmission
`scheme and
`wherein the second communication system has pilot symbols that are denser than those in the first communication system;
`generating at least one non-data section containing information describing an aspect of data in at least one of the first section and the
`second section; and
`combining the first section, the second section and the at least one non-data section to form the frame structure.

`presented both with respect to 802.11ac-2013 and 802.11-2016.
`
`IEEE 802.11ax (IEEE 802.11ax-Draft 8.0) currently exists as an approved draft amendment to the 802.11 standard, and the
`amendment contains changes to the 2020 release of the standard (IEEE 802.11-2020). Evidence of infringement will be
`presented both with respect to 802.11-2020 and 802.11ax-D8.0.
