Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Arguments
Applicant's arguments filed 3/11/26 have been fully considered but they are not persuasive.
Regarding claims 6-8, applicant has not argued the rejection of the claims nor amended the claims, so the previous rejection still applies.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 6-8 are rejected under 35 U.S.C. 103 as being unpatentable over Kumar (11,159,355) in view of Yeh and Ko.
Regarding claim 6, Kumar discloses a method of a second communications node (wireless system consisting of a base station and user equipment) comprising, receiving from a first communications node, a signal consisting of modulations symbols generated by modulating a base sequence associated with a physical cell identity (Col. 15;55-60 or Col. 17;43-47), obtaining the physical cell identity from signal using base sequences (Col;35-55), and wherein each of the base sequences is generated based on sequences of a first through third binary sequence (Figure 4, 3 signals being generated for OFDM based on a Zadoff Chen sequence). Kumar does not disclose that use of 2M elements based on distributed concatenation or the second intermediate base sequence being generated by modifying the first base sequence.
Yeh teaches a method of a first communications node (transmitter)comprising: generating a first intermediate base sequence consisting of M elements based on first-third binary sequences (Fig 1a, first parallel path, abstract, para 26), generating a base sequence of M elements by modifying the first intermediate base sequence (Fig 1a, second parallel path which is the inverse, para 29). Yeh further discloses generating a base sequence based on distributed concatenation (i.e. combining signals) of the first and second signals (para 16-17) and mapping modulation symbols onto subcarriers (data to subcarrier mapper) and transmitting a signal consisting of the mapped modulation signals to a second communication node (para 16-20, signals are transmitted to be received by the OFDM receiver). Yeh does not explicitly disclose the base sequence consisting of 2M elements.
Ko, in an analogous art, teaches that in an OFDM system (para 117) the combination of 2 sets of signals that are length M to result in a concatenated signal which is 2M elements (Figure 55, para 383 – adding signals B/C to A which results in a pilot that is 2x the length of A alone). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to include a larger pilot and modify a second sequence based on the first sequence in order reduce errors in reception.
Regarding claims 7-8, Kumar further discloses that symbols are detected by the UE (Figs 10-11) and that the use of correlation values to determine the physical cell id (Col 7;49-56) as well as the use of the PSS as part of the signal process to detect the physical cell identity (Col. 15, lines 1-5).
Allowable Subject Matter
Claims 1-5, 9-13 are allowed.
The following is an examiner’s statement of reasons for allowance:
Claims 1 and 9 are directed to a communication node which generates multiple intermediate base sequences. The first intermediate sequence uses a physical cell identity as well as 3 binary sequences. None of the cited prior art teaches nor fairly suggests the transformation of these symbols such that a first intermediate base sequence is entirely different from the first to third binary sequences as recited in claims 1 and 9.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure
Rico Alvarino (2018/0220426) discloses binary sequences combined via pseudo-random generation and vectors.
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
