CTNF 18/789,057 CTNF 91630 Detailed Action The office action is in response to the communications filed on 07/30/2024 . Notice of AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Claims Status Claims 1-20 are pending in this application. Response to Amendment Applicant’s preliminary amendment, filed 09/26/2024 , has been entered and considered. Information Disclosure Statement The information disclosure statement (IDS) submitted on 05/09/2025 and 10/03/2024 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Prior Art Made of Record 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Zhang et al. (Publication No. US 2020/0112994), the prior art relates to the preamble cyclic prefix 320 may be extended to a larger length or longer time period to enable the preamble portion 310 to be used as a DMRS for payload portion; see ¶ 133 . Allowable Subject Matter 07-43-02 AIA Claim s 2, 13-16, and 18 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. 12-151-08 AIA 07-43 12-51-08 Claim s 3-10 and 19-20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claims 2, 13-16, and 18 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. Regarding Claims 2, 13, and 18, the claim recites: (first limitation) “wherein the first cyclic prefix is the same as a first subset of the first transmit symbol”; (second limitation) “wherein a start location of the first subset is before a first reference point”; (third limitation) “wherein a first end location of the first subset is a second end location of the first transmit symbol”, or (fourth limitation) “wherein the first reference point is a location for intercepting the second cyclic prefix”. Based on the context of the claim is ambiguous the position of the different elements (e.g. subset or cyclic prefix) in the first transmit symbol. As a result, the claim is indefinite. Examiner suggest to describe the elements position relative to each other. For example, the first transmit symbol comprises the first cyclic prefix and a subset, wherein the first cyclic prefix is defined from a first reference point to a second reference point, wherein the subset is defined from the second reference point to a third reference point; and wherein the second transmit symbol comprises the second cyclic prefix, and wherein the third reference point is a location for intercepting the second cyclic prefix. Regarding Claim 14, the claim recites: the second transmit symbol comprises a first sequence, and an end location of the first sequence is an end location of the second transmit symbol; and the first sequence is an all-zero sequence; or the first sequence is the same as a third subset of the first transmit symbol, and an end location of the third subset is a location for intercepting the cyclic prefix in the first transmit symbol. Based on the context of the claim is ambiguous the position of the different elements (e.g. subset or cyclic prefix) in the first transmit symbol. As a result, the claim is indefinite. Regarding Claims 15-16, the claims are rejected as they inherited the deficiencies of the parent claim and have not resolved the deficiencies. Therefore, they are rejected based on the same rationale as applied to the parent claim above. Claim Rejections - 35 USC § 103 07-20-fti The following is a quotation of AIA 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. 07-23-aia AIA The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under AIA 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1, 11-12, and 17 are rejected under AIA 35 U.S.C. 103 as being unpatentable over Nam et al. (Publication No. US 2022/0070037, hereinafter referred as Nam) in view of Hung et al. (Publication No. US 2020/0287679, hereinafter referred as Hung). Regarding claim 1 and 17, Nam discloses a symbol processing method, comprising (A process flow supporting the generation of symbols for communication between a transmitting wireless device and a receiving wireless device; see figure 7.) : generating, by a transmitting end, a first transmit symbol and a second transmit symbol (The transmitting wireless device (e.g. UE) generate set of symbols [first/second symbol]; see figure 7 step 705.) , sending, by the transmitting end, the first transmit symbol and the second transmit symbol (The transmitting wireless device may transmit the set of symbols to the receiving wireless device; see figure 7 step 720.) , wherein the first transmit symbol and the second transmit symbol are consecutive in time domain (The transmitting wireless device may transmit the symbols [first/second symbol]; within the burst sequentially such that sequential symbols are positioned adjacent [consecutive] to one another in the time domain; see ¶ 178.) , and the first transmit symbol is located after the second transmit symbol in time domain (For example, the transmitting wireless device may transmit the second symbol immediately following the first symbol; see ¶ 178.) ; and wherein the first transmit symbol is a symbol that carries a reference signal, and the second transmit symbol is a symbol that carries a data signal (Resource allocation scheme that supports time-domain pattern comprising a DRMS signal follow by a data signal; see figure 6) . Nam discloses the generation of symbols by adding a cyclic prefix, but fails to explicitly disclose a length of a cyclic prefix of the first transmit symbol is greater than a length of a cyclic prefix that corresponds to a subcarrier spacing of the first transmit symbol. However, in analogous art, Hung discloses selecting a smaller numerology number (corresponding to a smaller subcarrier spacing), such that the length of the cyclic prefix is longer; see ¶ 65. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Nam with the cyclic prefix length of Hung in order to enable adjusting the cell coverage according to the actual condition of the radio resource. Regarding claim 11, Nam discloses a symbol processing method, comprising (A process flow supporting the generation of symbols for communication between a transmitting wireless device and a receiving wireless device; see figure 7.) : obtaining, by a receiving end, a first transmit symbol and a second transmit symbol (The transmitting wireless device (e.g. UE) generate set of symbols [first/second symbol]; see figure 7 step 705. The transmitting wireless device may transmit the set of symbols to the receiving wireless device; see figure 7 step 720.) , the first transmit symbol and the second transmit symbol are consecutive in time domain, and the first transmit symbol is located after the second transmit symbol in time domain (The transmitting wireless device may transmit the symbols [first/second symbol]; within the burst sequentially such that sequential symbols are positioned adjacent [consecutive] to one another in the time domain; see ¶ 178. For example, the transmitting wireless device may transmit the second symbol immediately following the first symbol; see ¶ 178.) ; and the first transmit symbol is a symbol that carries a reference signal, and the second transmit symbol is a symbol that carries a data signal (Resource allocation scheme that supports time-domain pattern comprising a DRMS signal follow by a data signal; see figure 6) ; and performing, by the receiving end, signal processing on the first transmit symbol and the second transmit symbol (The receiving wireless device receive [processing] the transmitted symbols; see figure 7 steps 720-735.). Nam discloses the generation of symbols by adding a cyclic prefix, but fails to explicitly disclose a length of a cyclic prefix of the first transmit symbol is greater than a length of a cyclic prefix that corresponds to a subcarrier spacing of the first transmit symbol. However, in analogous art, Hung discloses selecting a smaller numerology number (corresponding to a smaller subcarrier spacing), such that the length of the cyclic prefix is longer; see ¶ 65. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Nam with the cyclic prefix length of Hung in order to enable adjusting the cell coverage according to the actual condition of the radio resource. Claim 12 is rejected under AIA 35 U.S.C. 103 as being unpatentable over Nam et al. (Publication No. US 2022/0070037, hereinafter referred as Nam) in view of Hung et al. (Publication No. US 2020/0287679, hereinafter referred as Hung) and further in view of Zhang et al. (Publication No. US 2020/0068435, hereinafter referred as Zhang). Regarding claim 12, Nam discloses the generation of symbols by adding a cyclic prefix, but fails to explicitly disclose performing, by the receiving end, a cyclic prefix removal operation on the first transmit symbol and the second transmit symbol, wherein cyclic prefixes are cyclic prefixes that correspond to subcarrier spacings of the first transmit symbol and the second transmit symbol. However, in analogous art, Zhang discloses the BS or the UE may receive a signal in a transmission period and may process the received signal by discarding CPs based on the CP configuration; see ¶ 89. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Nam with the discarding mechanism of Hung in order to recover the original information data bits transmitted by the transmitter.
