DETAILED ACTION 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 . Claims 1-32 have been examined. Claim Objections Claim 3, 6, 15, 19, 22 and 31 are objected to because of the following informalities: Claim 3 line 2 “the control channel time offset” should read --the control channel signal time offset— Claim 6 line 1 “control channel is” should read --control channel signal is— Claim 6 line 2 “primary signal” should read –primary synchronization signal— Claim 6 line 3 “secondary signal” should read –secondary synchronization signal-- Claim 6 line 3-4 “the control channel comprises” should read --the control channel signal comprises— Claim 6 line 4 “the value” should read –the function value— Claim 6 line 5 “the value” should read –the function value— Claim 15 line 1 “channel reception” should read --channel signal reception— Claim 19 line 2-3 “the control channel time offset” should read --the control channel signal time offset— Claim 22 line 1 “control channel is” should read --control channel signal is— Claim 22 line 2 “primary signal” should read –primary synchronization signal— Claim 22 line 3 “secondary signal” should read –secondary synchronization signal-- Claim 22 line 4 “the control channel comprises” should read --the control channel signal comprises— Claim 22 line 5 “the value” should read –the function value— Claim 22 line 6 “the value” should read –the function value— Claim 31 line 1 “channel reception” should read --channel signal reception— Appropriate correction is required. 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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 2-3, 13, 18-19, and 28-29 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. In reference to claim 2 Claim 2 recites the limitation "the control channel transmission" in line 2. There is insufficient antecedent basis for this limitation in the claim. In reference to claim 3 Claim 3 recites the limitation "the control channel transmission" in line 3. There is insufficient antecedent basis for this limitation in the claim. In reference to claim 18 Claim 18 recites the limitation "the control channel transmission" in line 2-3. There is insufficient antecedent basis for this limitation in the claim. In reference to claim 19 Claim 19 recites the limitation "the control channel transmission" in line 3. There is insufficient antecedent basis for this limitation in the claim. In reference to claim 28 Claim 28 recites the limitation "the physical broadcast channel" in line 3. There is insufficient antecedent basis for this limitation in the claim. In reference to claim 13 and 29 Claims 13 and 29 is rejected because it depends on rejected parent claim. Allowable Subject Matter Claims 1, 4-5, 7-12, 14, 16-17, 20-21, 23-27, 30, and 32 are allowed. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure are: US 2024/0389037 pertains to receiving a single-carrier SSB structure from a radio access network. Here, the single-carrier SSB structure includes: a PSS portion comprising a PSS block mapped to a first set of time-domain symbols, a SSS portion comprising a SSS block mapped to a second set of time-domain symbols, and a PBCH portion comprising a plurality of PBCH blocks mapped to a third set of time-domain symbols. The method includes accessing a cell using a single-carrier waveform based on the received single-carrier SSB structure. US 12256441 pertains to a two-step random access channel (RACH) process, the base station determines a random access configuration to configure a user equipment (UE) with the two-step RACH process that includes a communication of a first message including a preamble portion and a payload portion, where the determining the random access configuration includes determining to exclude a demodulation reference signal (DMRS) from the payload portion based on satisfaction of conditions. The base station generates configuration information including the random access configuration indicating the two-step RACH process, the configuration information including a configuration for a transmission of the preamble portion and the payload portion without the DMRS based on the satisfaction of the conditions. Any inquiry concerning this communication or earlier communications from the examiner should be directed to BRIAN S ROBERTS whose telephone number is (571)272-3095.
