(note: media: a physical non-transitory computer-readable medium. Examples of suitable media include RAM, ROM, magnetic media such as a hard-drive or a floppy disk, or an optical medium such as a compact disk (CD) or DVD (digital versatile disk), flash memory, and the like, or any combination of such storage or transmission devices (par. 198).
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 08/11/2026 has been entered.
Response to Arguments
Applicant's arguments filed 07/13/2026 have been fully considered but they are not persuasive.
In response to applicant’s argument in pages 8-9, the applicant asserts that “Applicant respectfully submits that neither Park nor Tervo teaches or suggests, either alone or in combination with each other, at least the above-quoted features of Applicant's amended independent claim 24.” Examiner respectively disagrees.
The applicant further asserts in page 9 that “the cited art does not teach or suggest, at least: "separate PT-RS patterns for the initial transmission and the retransmission of the TB" as recited in Applicant's amended independent claim 24. (Emphasis added).: Examiner respectively disagrees.
As indicated by the office action, in fig. 4A, par. 78, 80 of PARK, the encoding of the signals or phase tracking reference signal as in par. 458, 459, 460, 501, 503 of PARK is prior to perform Fourier transform for transmission. Therefore, the precoding or encoding of the PT-RS samples of separate PT-RS patterns as being disclosed by par. 458, 459, 460,494-496, 501, 503 to insert the PT-RS samples is prior to discrete Fourier transform (DFT) operation. Therefore, PARK teaches “wherein the separate PT-RS patterns comprise multiple groups of PT-RS samples inserted prior to a discrete Fourier transform (DFT) operation” and the combination of the prior art would teach the claims.
The rejection is maintained.

(US 20230283429 with foreign app. KR 10-2020-0089182 filed on 07/17/2020, KR 10-2020-0091954 filed on 07/23/2020, KR 10-2020-0134692 filed on 10/16/2020, herein as PARK) in view of TERVO et al. (US 20230006794).
Regarding claim 24, PARK et al. (US 20230283429) teaches an apparatus comprising:
memory to store phase tracking reference signal (PT-RS) information for initial transmission and retransmission of a transport block (TB) within physical uplink shared channel (PUSCH) (par. 63, 64, 67, 458, 459, 460, 501, 503, storage…The base station maps the PT-RS to physical resources via the following procedures to transmit a PT-RS for a PDSCH during initial transmission or retransmission…First, for PT-RS mapping, the terminal assumes that the PT-RS exists only in a resource block used for the corresponding PDSCH (the same even for a PUSCH PT-RS); base station or terminal); and
processing circuitry, coupled with the memory (par. 63, 64, 67, 548, 459, 460, base station or terminal), to:
retrieve the PT-RS information from the memory (par. 63, 67, 548, 459, 460, base station or terminal);
determine a PT-RS pattern for the PUSCH utilizing MCS index based on the PT-RS information, wherein the PT-RS information includes separate PT-RS patterns for the initial transmission and the retransmission of the TB (par. 494-497, 499, When the UE is receiving a PDSCH for retransmission, in case that the UE is scheduled or configured with an MCS index greater than V, an MCS for PT-RS time density determination may be obtained based on DCI received for the same TB scheduled or configured with an MCS index equal to or smaller than V in initial transmission; par. 459, 460, The base station maps the PT-RS to physical resources via the following procedures to transmit a PT-RS for a PDSCH during initial transmission or retransmission… First, for PT-RS mapping, the terminal assumes that the PT-RS exists only in a resource block used for the corresponding PDSCH (the same even for a PUSCH PT-RS)), wherein the separate PT-RS patterns comprise multiple groups of PT-RS samples inserted prior to a discrete Fourier transform (DFT) operation (fig. 4A, par. 78, 80, 503, The encoding and modulation unit 402 performs channel encoding… The multiple transmission paths 406-1 to 406-N may convert a digital beamformed digital signal into an analog signal. To this end, each of the multiple transmission paths 406-1 to 406-N may include an inverse fast fourier transform (IFFT) operation unit, a cyclic prefix (CP) insertion unit, a DAC, and an up-conversion unit…PT-RS to be mapped to position m before transform precoding is generated as follows (wherein, m is a value dependent on the number N.sub.group.sup.PT-RS of PT-RS groups, the numbers M.sub.SC.sup.PUSCH and N.sub.samp.sup.group of samples per PT-RS group (Scheduled bandwidth for uplink transmission, expressed as a number of subcarriers)); par. 459, 460, 494-496, 499); and
encode the PUSCH based on the separate PT-RS patterns (par. 459, 460, The base station maps the PT-RS to physical resources via the following procedures to transmit a PT-RS for a PDSCH during initial transmission or retransmission… First, for PT-RS mapping, the terminal assumes that the PT-RS exists only in a resource block used for the corresponding PDSCH (the same even for a PUSCH PT-RS); par. 494-496, 499).
However, PARK does not teach determine a PT-RS pattern for the PDSCH utilizing a Discrete Fourier Transform- spread-OFDM (DFT-s-OFDM) waveform.
But, TERVO et al. (US 20230006794) in a similar or same field of endeavor teaches determine a PT-RS pattern for the PDSCH utilizing a Discrete Fourier Transform- spread-OFDM (DFT-s-OFDM) waveform (par. 45, 48, 50, 51, 52, DFT-s-OFDM is supported in UL, and the presence of a PTRS pattern is UE-specifically configurable (i.e., whether it exists or not), and multiple patterns/densities…receiver needs may be separately optimized for different patterns… several scenarios may be provided including, for example, physical downlink shared channel (PDSCH)/physical uplink shared channel (PUSCH)… the rank dependent PTRS configuration may be dependent upon the communication scenario. For example, PTRS configuration for rank-1 may be characterized by means of two parameters: M and N (M×N), where M represents the number of PTRS groups per DFT-s-OFDM symbol, and N is the number of PTRS samples (symbols) per group).
Thus, it would have been obvious to the person of ordinary skill in the art before the effectively filing date of the claimed invention to implement the system or method as taught by TERVO in the system of PARK to determine PR-RS pattern.
The motivation would have been to lower peak-to-average power ratio (PAPR) and provide better coverage and more robust for phase noise than frequency-domain PTRS.

However, PARK does not teach determine phase tracking reference signal (PT-RS) information utilizing a Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) waveform.

(US 20230283429 with foreign app. KR 10-2020-0089182 filed on 07/17/2020, KR 10-2020-0091954 filed on 07/23/2020, KR 10-2020-0134692 filed on 10/16/2020, herein as PARK) and TERVO et al. (US 20230006794) as applied to claims 30, 38 above, and further in view of YE et al. (US 20210321403).
Regarding claim 37, PARK et al. (US 20230283429) does not teach the one or more computer-readable media of claim 33, wherein the first PT-RS pattern is in common with the second PT-RS pattern.
But, YE et al. (US 20210321403) in the same or similar field of endeavor teaches wherein the first PT-RS pattern is in common with the second PT-RS pattern (par. 39, the frequency density of PT-RS does not change between initial transmission and retransmissions).
Thus, it would have been obvious to the person of ordinary skill in the art before the effectively filing date of the claimed invention to implement the system or method as taught by YE in the system of PARK and TERVO to transmission PT-RS in pattern.
The motivation would have been to reduce the overhead signaling and storage.
Regarding claim 43, PARK et al. (US 20230283429) does not teach the one or more computer-readable media of claim 38, wherein the PT-RS information includes a PT-RS pattern to be used for both the initial transmission of the TB and retransmission of the TB.
But, YE et al. (US 20210321403) in the same or similar field of endeavor teaches wherein the PT-RS information includes a PT-RS pattern to be used for both the initial transmission of the TB and retransmission of the TB (par. 39, the frequency density of PT-RS does not change between initial transmission and retransmissions).
Thus, it would have been obvious to the person of ordinary skill in the art before the effectively filing date of the claimed invention to implement the system or method as taught by YE in the system of PARK and TERVO to transmission PT-RS in pattern.
The motivation would have been to reduce the overhead signaling and storage.
Claim(s) 40 is/are rejected under 35 U.S.C. 103 as being unpatentable over PARK et al. (US 20230283429 with foreign app. KR 10-2020-0089182 filed on 07/17/2020, KR 10-2020-0091954 filed on 07/23/2020, KR 10-2020-0134692 filed on 10/16/2020, herein as PARK) and TERVO et al. (US 20230006794) as applied to claims 39 above, and further in view of MATSUMURA et al. (WO 2020250360 herein MATSUMURA ‘360).
Regarding claim 40, PARK et al. (US 20230283429) teaches the one or more computer-readable media of claim 39, wherein the media further stores instructions to cause the gNB to encode a message for transmission to a UE that includes the MCS thresholds (par. 12, 459, 460, 478, PTRS-DownlinkConfig indicate thresholds ptrs-MCSi (i=1,2,3) and NRB,i (i=0,1)).
However, PARK does not teach wherein the message is encoded for transmission via minimum system information (MSI), remaining minimum system information (RMSI), other system information (OSI) or dedicated radio resource control (RRC) signaling.
But, MATSUMURA ‘360 in a similar or same field of endeavor teaches wherein the message is encoded for transmission via minimum system information (MSI), remaining minimum system information (RMSI), other system information (OSI) or dedicated radio resource control (RRC) signaling (XIAOLIN par. 30, The broadcast information includes, for example, a master information block (MIB: Master Information Block), a system information block (SIB: System Information Block), a minimum system information (RMSI: Remaining Minimum System Information), and other system information (OSI: Other). System Information) may be used).
Thus, it would have been obvious to the person of ordinary skill in the art before the effectively filing date of the claimed invention to implement the system or method as taught by MATSUMURA ‘360 in the system of PARK and TERVO to transmission PT-RS in pattern.
The motivation would have been to provide scalable to different technologies.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
CHOI et al. (US 20230189264) teaches a PT-RS sequence may be inserted in units of samples for each DFT-s-OFDM symbol before DFT precoding. The same number of samples may be defined as one group, and the number of groups per DFT-s-OFDM symbol and the number of samples in a group (par. 199).
