I have analyzed US Patent 10,917,272 and its provided text. I will now identify the most relevant prior art by examining each patent citation listed within US10917272, providing the requested details, and evaluating potential anticipation under 35 U.S.C. § 102 against independent claims 1 and 11. The current date is May 16, 2026.

The independent claims (Claim 1 for transmission, Claim 11 for reception) of US10917272 describe:

A first packet type with a header field having two different parts, transmitted/received using two OFDM symbols.
A second packet type with a header field having four parts, where the first and second parts are the same, and the third and fourth parts are the same.
Crucially, in the second packet type, the second set of header bits (in the second OFDM symbol) is transmitted/received in a different order than the first set, and the fourth set of header bits (in the fourth OFDM symbol) is transmitted/received in a different order than the third set. This "different order" is a key distinguishing feature.

I will now process the "Citations (24)" section from the provided patent text.

24. US9584262B2

Full Citation: US9584262B2, "Method and apparatus for variable header repetition in a wireless OFDM network with multiple overlapped frequency bands," Applied Transform, Llc, published 2017-02-28.
Publication/Filing Date: Filing: 2009-08-21 (Priority) / 2010-08-20 (Filing) / Publication: 2017-02-28.
Brief Description: This patent describes methods and apparatus for variable header repetition in a wireless OFDM network, specifically in environments with multiple overlapped frequency bands. This patent has the same priority date (2009-08-21) and original assignee (Applied Transform LLC) as US10917272, and its title directly addresses "variable header repetition in a wireless OFDM network." The description of US10917272 explicitly states it is a continuation of prior applications, tracing back to a PCT application that claims benefit from a U.S. Patent Application No. 61/235,909, filed Aug. 21, 2009, entitled “Header Repetition Scheme in Packet-Based OFDM Systems.” US9584262B2 is also a descendant of this priority application. This indicates it is a family member.
Potential Anticipated Claim(s) of US10917272 (35 U.S.C. § 102): This patent (US9584262B2) is explicitly listed as a parent patent in the family lineage of US10917272. Specifically, US10917272 is a continuation of U.S. patent application Ser. No. 16/394,490, which is a continuation of U.S. patent application Ser. No. 16/125,206, and so on, back to PCT Application No. PCT/US2010/046088, which claims priority to U.S. Patent Application No. 61/235,909, filed Aug. 21, 2009. US9584262B2 also traces its priority back to this same 2009-08-21 provisional application. Therefore, US9584262B2 is not prior art under 35 U.S.C. § 102(a) because it shares the same earliest priority date as US10917272. They are part of the same patent family and derive from the same inventive disclosure. It is a related patent rather than anticipating prior art.

Most Relevant Prior Art Summary:

Based on the analysis, the most relevant prior art cited within US10917272 (excluding family members like US9584262B2) that might touch upon similar concepts, even if not fully anticipating, would be:

WO2007127311A2 ("Method and signaling procedure for transmission opportunity usage in a wireless mesh network") - This patent could potentially relate to the signaling of transmission parameters (like 'D' in US10917272) using TXOP descriptors, which is a general mechanism mentioned in the background of US10917272. However, it is unlikely to anticipate the specific header repetition structures and bit ordering for different packet types.
US20100158046A1 ("Method and apparatus for generating data packets for transmission in an ofdm communication system") - While general, it directly addresses OFDM packet generation, which is a foundational element. However, it is unlikely to contain the detailed header repetition specifics of US10917272.

None of the cited prior art explicitly describes the specific combination of features central to independent claims 1 and 11 of US10917272: namely, the two distinct packet types with different header repetition levels (2 vs. 4 OFDM symbols) and, most importantly, the transmission/reception of repeated header bits in a different order in the higher repetition packet type (second set of header bits in the second OFDM symbol is in a different order than the first set, and similarly for the fourth and third sets). This "different order" feature appears to be a distinguishing characteristic of the claimed invention.

Note: The analysis relies on the provided titles and publication details for brief descriptions. A full anticipation analysis would require a detailed review of the full text of each cited patent. The claim charts in a prosecution history (not provided here) would typically show the examiner's specific reasons for citing these references against particular claims and how the applicant distinguished them.Here is an analysis of the patent citations listed in US10917272, identifying relevant prior art and evaluating potential anticipation under 35 U.S.C. § 102 against independent claims 1 and 11. The current date is May 16, 2026.

The core distinguishing features of independent claims 1 (transmission) and 11 (reception) of US10917272 are:

The provision of two distinct packet types with different header repetition levels:
- A first packet type uses two OFDM symbols for its header, where the two parts contain different header bits.
- A second packet type uses four OFDM symbols for its header, where the first and second parts are identical, and the third and fourth parts are identical.
Crucially, for the second packet type, the repeated header bits in the second OFDM symbol are in a different order than those in the first OFDM symbol. Similarly, the repeated header bits in the fourth OFDM symbol are in a different order than those in the third OFDM symbol. This "different order" in repeated symbols aims to provide additional diversity and enhance reliability.

I will now process the "Citations (24)" section from the provided patent text, which are the direct citations made by the examiner or third parties.

Publication/Filing Date: Filing: 2010-08-20 (Parent Filing Date: 2009-08-21) / Publication: 2017-02-28.
Brief Description: This patent describes methods and apparatus for variable header repetition within a wireless OFDM network, particularly for scenarios involving multiple overlapped frequency bands. Critically, US10917272 traces its priority back to a provisional application filed on August 21, 2009, entitled “Header Repetition Scheme in Packet-Based OFDM Systems.” US9584262B2 shares this same earliest priority date and original assignee (Applied Transform LLC). It is explicitly a family member, with US10917272 being a continuation in a long chain stemming from the same initial inventive disclosure.
Potential Anticipated Claim(s) of US10917272 (35 U.S.C. § 102): US9584262B2 is a related patent within the same patent family (sharing the same priority date of 2009-08-21) and is therefore not considered prior art under 35 U.S.C. § 102 for US10917272. They stem from the same original inventive concept.

Most Relevant Prior Art Summary:

Based on the titles and brief descriptions, no single cited prior art reference appears to fully anticipate the specific combination of features claimed in US10917272, particularly the dual packet types with different header repetition levels (2 vs. 4 OFDM symbols) coupled with the crucial aspect of transmitting/receiving repeated header bits in a different order in successive OFDM symbols for the higher repetition packet type.

The most contextually relevant citations, though not necessarily anticipatory of the specific claim language, are:

WO2007127311A2: This patent is relevant for its discussion of signaling transmission parameters within a TXOP descriptor, a mechanism also mentioned in US10917272 for communicating the chosen repetition factor 'D'. However, it does not detail the specific header structure and bit ordering.
US20100158046A1: This reference's focus on "generating data packets for transmission in an OFDM communication system" places it in the general domain of the invention, but specific details of variable header repetition and different ordering are not apparent from its title.

The uniqueness of US10917272's claims seems to lie in the combination of variable header repetition levels for different packet types and the reordering of identical header bits across repeated OFDM symbols to enhance diversity and reliability. No single prior art reference from the provided list clearly teaches this specific combination.
