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.
The factual inquiries for establishing a background for determining obviousness under 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1, 7, and 13 are rejected under 35 U.S.C. 103 as being unpatentable over (Samsung; "Discussion on numerology aspects of NR synchronization signal; 3GPP TSG RAN WG1 Meeting #86; R1-166795; Gothenburg, Sweden, 22nd – 26th August 2016", hereinafter Samsung), in view of Ryu et al. (US 20180092064 A1), hereinafter Ryu.
Regarding claim 1, Samsung discloses a method of enabling synchronization in a wireless communication network, the method comprising:
a base station of the wireless communication network applying one subcarrier spacing from a set of multiple subcarrier spacings, which are supported for transmission of synchronization signals, ([Introduction] “The design of synchronization signals for NR needs to consider various aspects and some are listed below: […] Information to be transmitted on synchronization signal(s), Design of synchronization signal(s) considering the support of multiple numerologies […] the support of multiple numerologies will allow NR to support different subcarrier spacings that will allow NR to be deployed in carrier frequencies not accessible to LTE.” […] NR specification to allow flexible support of multiple numerologies. More specifically, the end goal is for NR to flexibly apply multiple subcarrier spacings (ex: 15 kHz scaled by an integer)]”);
wherein the applied subcarrier spacing is included in a subset of one or more subcarrier spacings, which depend on a set of frequency ranges in which the base station is configured to transmit, ([Introduction] “RAN1 assumes that multiple (but not necessarily all) OFDM numerologies (equivalent to “subcarrier spacings”) can apply to the same frequency range […] For a NR carrier (from network perspective) using multiple numerologies, at least the following is for further study […] Multiple frequency/time portions using different numerologies share a synchronization signal […] The synchronization signal refers to the signal itself and the time-frequency resource used to transmit the synchronization signal”), and based on a mapping of the one or more subcarrier spacings to the frequency ranges, the base station transmitting synchronization signals based on the applied subcarrier spacing of the subset, ([3.1 Alternative 1:] “‘default’ subcarrier spacing for (equivalent to “mapping”) a given carrier frequency range. In this case, the subcarrier spacing for synchronization signal(s) shall be pre-defined in NR specification”).
However, Samsung does not disclose, wherein the base station communicates information about subcarrier spacings used by neighboring base stations, and wherein for each of the transmitted synchronization signals a length of a cyclic prefix of modulation symbols is based on the utilized subcarrier spacing.
In the same field of endeavor, Ryu discloses wherein the base station communicates information about subcarrier spacings used by neighboring base stations, ([0086] [0104] “the default numerology (equivalent to “subcarrier spacing” par. [0086]) used by cell A and the default numerology used by cell B may be different from each other. The terminal may acquire default numerology information of different cells through the synchronization channel. However, this may increase a blind detection frequency of the terminal for the numerology detection, thereby increasing power consumption of the terminal. Accordingly, a serving base station may transmit the cell ID of the neighboring base stations and the numerology information of the neighboring base stations to the serving base station through the system information (SIB, RMSI, or OSI) or the UE-specific RRC signaling”), wherein for each of the transmitted synchronization signals a length of a cyclic prefix of modulation symbols is based on the utilized subcarrier spacing, ([0092] [0086] “various cases described above, the synchronization channel may be transmitted using various numerologies. At this time, the numerology means at least one of a subcarrier spacing of the synchronization signal, a cyclic prefix (CP) length of the synchronization signal, a synchronization channel bandwidth of the synchronous channel, and a fast Fourier transform size of the synchronization signal”).
Therefore, it would have been obvious for one of ordinary skill in the art before
the effective filing date of the claimed invention to have modified the synchronization signals for NR, disclosed by Samsung ([Introduction]), to incorporate the serving base station, disclosed by Ryu. One of ordinary skill in the art would have been motivated to make this modification to enable a transmission of the cell ID of the neighboring base stations, Ryu ([0086] [0104]).
Regarding claim 7, Samsung discloses a base station, comprising:
a radio interface (not shown but inherent in all network devices such as the “eNB” discussed (Samsung [Introduction, 7th paragraph]); configured to connect to one or more wireless communication devices in a wireless communication network; and
at least one processor (not shown but inherent in all network devices such as “eNB” discussed [Samsung Introduction, 7th paragraph]);
the at least one processor being configured to:
apply one subcarrier spacing from a set of multiple subcarrier spacings, which
are supported for transmission of synchronization signals, ([Introduction] “The design of synchronization signals for NR needs to consider various aspects and some are listed below: […] Information to be transmitted on synchronization signal(s), Design of synchronization signal(s) considering the support of multiple numerologies […] the support of multiple numerologies will allow NR to support different subcarrier spacings that will allow NR to be deployed in carrier frequencies not accessible to LTE.” […] NR specification to allow flexible support of multiple numerologies. More specifically, the end goal is for NR to flexibly apply multiple subcarrier spacings (ex: 15 kHz scaled by an integer)]”);
wherein the applied subcarrier spacing is included in a subset of one or more subcarrier spacings, which depend on a set of frequency ranges in which the base station is configured to transmit, ([Introduction] “RAN1 assumes that multiple (but not necessarily all) OFDM numerologies (equivalent to “subcarrier spacings”) can apply to the same frequency range […] For a NR carrier (from network perspective) using multiple numerologies, at least the following is for further study […] Multiple frequency/time portions using different numerologies share a synchronization signal […] The synchronization signal refers to the signal itself and the time-frequency resource used to transmit the synchronization signal”);
and based on a mapping of the one or more subcarrier spacings to the frequency ranges, transmit synchronization signals based on the applied subcarrier spacing of the subset, ([3.1 Alternative 1:] “uses one ‘default’ subcarrier spacing for (equivalent to “mapping”) a given carrier frequency range. In this case, the subcarrier spacing for synchronization signal(s) shall be pre-defined in NR specification. Error! Reference source not found. shows an example of how this alternative could apply”);
However, Samsung does not disclose wherein the base station communicates information about subcarrier spacings used by neighboring base stations, and wherein for each of the transmitted synchronization signals a length of a cyclic prefix of modulation symbols is based on the utilized subcarrier spacing.
In the same field of endeavor, Ryu discloses wherein the base station communicates information about subcarrier spacings used by neighboring base stations, ([0086] [0104] “the default numerology (equivalent to “subcarrier spacing” par. [0086]) used by cell A and the default numerology used by cell B may be different from each other. The terminal may acquire default numerology information of different cells through the synchronization channel. However, this may increase a blind detection frequency of the terminal for the numerology detection, thereby increasing power consumption of the terminal. Accordingly, a serving base station may transmit the cell ID of the neighboring base stations and the numerology information of the neighboring base stations to the serving base station through the system information (SIB, RMSI, or OSI) or the UE-specific RRC signaling”), wherein for each of the transmitted synchronization signals a length of a cyclic prefix of modulation symbols is based on the utilized subcarrier spacing, ([0092] [0086] “various cases described above, the synchronization channel may be transmitted using various numerologies. At this time, the numerology means at least one of a subcarrier spacing of the synchronization signal, a cyclic prefix (CP) length of the synchronization signal, a synchronization channel bandwidth of the synchronous channel, and a fast Fourier transform size of the synchronization signal”).
Therefore, it would have been obvious for one of ordinary skill in the art before
the effective filing date of the claimed invention to have modified the synchronization signals for NR, disclosed by Samsung ([Introduction]), to incorporate the serving base station, disclosed by Ryu. One of ordinary skill in the art would have been motivated to make this modification to enable a transmission of the cell ID of the neighboring base stations, Ryu ([0086] [0104]).
Regarding claim 13, as applied to claim 7 above, Samsung discloses, and the one or more wireless communication devices, ([Introduction, 7th paragraph] “The design of synchronization signals for NR needs to consider various aspects and some are listed below: […] the support of multiple numerologies will allow NR to support different subcarrier spacings that will allow NR to be deployed in carrier frequencies not accessible to LTE.” “[…] details are provided on how it might impact the specification support and details on the relevant UE/eNB implementation implications”).

One or more of the following properties (or criteria) may be used to determine priority order and/or properties used in other systems (such as a type of information carried by a transmission): (i) a numerology parameter applicable to a numerology block or transmission (e.g., scaling may be applied to transmissions using a lower subcarrier spacing”).

Claims 6 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over (Samsung; "Discussion on numerology aspects of NR synchronization signal; 3GPP TSG RAN WG1 Meeting #86; R1-166795; Gothenburg, Sweden, 22nd – 26th August 2016", hereinafter Samsung), in view of Ryu et al. (US 20180092064 A1), hereinafter Ryu, further in view of Dinan et al. (US 8427976 B1), hereinafter Dinan.

One of ordinary skill in the art would have been motivated to make this modification to enable the serving BS to accurately make a handover decision, thus send a message to the target BS, Dinan ([page 32, column 37, line 22-28]).
Regarding claim 12, as applied to claim 7 above, Samsung as modified by Ryu does not disclose wherein the at least one processor is further configured to: receive information indicating one or more subcarrier spacings supported by a further base station; and depending on the received information, control handover of a wireless communication device between the base station and the further base station.

Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the synchronization signals for NR, disclosed by Samsung ([introduction]), as modified by Ryu to incorporate the measurement report disclosed by Dinan. One of ordinary skill in the art would have been motivated to make this modification to enable the serving BS to accurately make a handover decision, thus send a message to the target BS, Dinan ([page 32, column 37, line 22-28]).
Response to Arguments
Applicant’s arguments with respect to independent claims 1 and 7 have been
considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Applicant’s arguments with respect to dependent claims 6 and 12 have been considered, but they are not persuasive.
Applicant argues, (p. 3-4), that column 37, lines 15-20 and lines 22-28 of Dinan reference cited in the previous action dated 02/13/2026 does not disclose or suggest the recited subcarrier spacing recitation directed to ‘“the base station receiving information indicating one or more subcarrier spacings supported by a further base station” and then controlling handover based on that information”’. However, the Examiner respectfully disagrees for the reasons laid out below.
Regarding the limitation, “the base station receiving information indicating one or more subcarrier spacings supported by a further base station”, Dinan, (col. 2, line 32-34) discloses “[…] a typical multicarrier OFDM system may include more subcarriers in a carrier. For example, the number of subcarriers in a carrier may be in the range of 10 to 10,000 subcarriers […]”). Therefore, the said limitation is taught by Dinan (column 37, line 15-20] “the serving base station may receive at least one measurement report from the wireless device […] report may comprise signal quality information of at least one of the at least one carrier (equivalent to “subcarrier” see col. 2, line 32-34) of at least one of the at least one target base station”).
Regarding the limitation, “then controlling handover based on that information”. As an alternate to Dinan (column 37, line 22-28] cited in the previous action, Dinan (column 31, line 6 – 15) disclose “The first base station may receive at least one fourth message from the second base station […]”, line 24 - 26) “The first base station may operate a wireless device handover using the association and/or based, at least in part, on information in the at least one fourth message as shown in 1010”).
Therefore, Dinan clearly discloses the limitations of “the base station receiving information indicating one or more subcarrier spacings supported by a further base station; depending on the received information, the base station controlling handover of a wireless communication device between the base station and the further base station”, and the rejection is maintained by the Examiner.
