Office Action

§103
DETAILED ACTION Claims status In response to the application filed on 03/26/2024, claims 1-20 are currently pending for the examination. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Notice of Pre-AIA or AIA Status In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Information Disclosure Statement The information disclosure statement (IDS) submitted on 03/26/2024 has been placed in the application file, and the information referred therein has been considered as to the merits. Drawings Drawing figures submitted on 03/26/2024 have been reviewed and accepted. 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 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 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 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over SHARMA et al. (US 2021/0409932 A1) in view of SI et al. (US 2020/0029238 A1). Regarding claim 1; Sharma teaches a user equipment (UE) comprising: two transceivers configured to enable wireless communications with a first base station; and a processor, communicatively coupled to the two or more transceivers, and configured to: measure, using the two or more transceivers, a first reference signal (See Fig. 6: At step S3, the mobile communication device 3 not only measures the CRS of the component carrier (i.e., first reference signal) used for the primary cell 7. ¶ [0096]) and a second reference signal (See Fig. 6: Thus, the mobile communication device 3 measures a different type of reference signal (i.e., second reference signal)—the CSI-RS in this embodiment—for the extension carrier as S3. ¶ [0096]) during a measuring period to determine a first measuring result of the first reference signal and a second measuring result of the second reference signal (See Figs. 2 and 6: the measurement period for the measurement of the CSI-RS RSRP/RSRQ for the CSI-RS on the extension carrier is advantageously dependent on the timing parameter. ¶ [0083]); generate one or more reports that include the first measuring result and the second measuring result (See Fig. 6: @S4, reporting results of measurements performed on the reference signals of the first type for the first component carrier and results of measurements performed on the reference signals of the second type for the second component carrier; ¶ [0020] and ¶ [0096]), wherein the report indicate that the first measuring result is associated with the second measuring (See Fig. 6: @S4: the mobile device to generate and report an associated measurement report comprising the results of the measurements (in this embodiment values of RSRP and RSRQ) and send it to the base station 5-1 at S4. ¶ [0096]); and transmit, using the one transceiver, the one or more reports to the first base station (See Fig. 6: @S4 the mobile device to generate and send an associated measurement report comprising the results of the measurements (in this embodiment values of RSRP and RSRQ) to the base station 5-1 at S4. ¶ [0096]). Sharma doesn’t explicitly state the measurement results are associated in time (domain) and using the two transceivers. However, SI further provides the measurement results are associated in time (domain) (SI- See Fig. 13: the time domain configuration of the measurement window may contain all the RSs (i.e., Reference Signals) for DRS based RRM measurement, such that UE assumes all the RSs for DRS based RRM measurement are within the measurement window. ¶ [0257]) and using the two transceivers (SI- See Fig. 2: a UE can be configured at least two RMTCs for a cell, wherein a first RMTC is utilized for RSSI measurement of signals/channels from NR-U, and a second RMTC is utilized for RSSI measurement of signals/channels from co-existing RATs (i.e., Multi Transceivers). ¶ [0320]). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to provide the measurement results are associated in time (domain) and using the two transceivers as taught by SI to have incorporated in the system of Sharma, so that it would provide to enhance the configuration of RMTC to address the utilization scenario of flexible numerology for the RSSI samples. SI: ¶ [0310]. [Office’s Note: Because of the alternative claim language such as “one or more”, only one of the alternative limitations has been analyzed by the examiner]. Regarding claim 2; Sharma teaches the UE wherein to measure the first reference signal and the second reference signal during the measuring period, the processor is further configured to: receive the first reference signal based on a first resource set during the measuring period; and receive the second reference signal based on a second resource set during the measuring period (Sharma: to perform measurements on the reference signals of the first type for the first component carrier, for use in determining a signal strength of the first component carrier and operable to perform measurements on the reference signals of the second type for the second component carrier, for use in determining a signal strength of the second component carrier; ¶ [0045]).

Regarding claim 4; Sharma teaches the UE of claim 2, wherein the processor is further configured to: receive the first reference signal from the first base station; and receive the second reference signal from a second base station (See Fig. 6: a first cell using a first component carrier and a second cell using a second component carrier. See Abstract). Regarding claim 5; Sharma teaches the UE wherein the first reference signal includes a channel state information reference signal (CSI-RS) (Sharma: positioning reference signals ‘PRS’ and/or may comprise channel state information reference signals ‘CSI-RS’. ¶ [0032]), and wherein the second reference signal includes a synchronization signal block (SSB) signal (Sharma: the extension carrier or second carrier carrying second reference signal may include: a Primary Synchronization Signal (PSS); a Secondary Synchronization Signal SSS. ¶ [0060]). Regarding claim 6; Sharma teaches the UE wherein the first measuring result includes a reference signal received power (RSRP) or a signal-to-interference-plus-noise ratio (SINR) of the first reference signal (SI: this disclosure can be utilized for SINR calculation for NR-U DRS based radio link monitoring as well. ¶ [0132]), and wherein the second measuring result includes a RSRP or a SINR of the second reference signal (Sharma: to determine a reference signal received power ‘RSRP’ for the second component carrier. ¶ [0028]). [Office’s Note: Because of the alternative claim language such as “or”, only one of the alternative limitations has been analyzed by the examiner]. Regarding claim 7; Sharma in view of Si teaches the UE wherein to generate the one or more reports, the processor is further configured to: receive a configuration message from the first base station, wherein the configuration message configures the processor to generate a report that includes the first measuring result and the second measuring result (Sharma: the mobile communication device 3 not only measures the CRS of the component carrier used for the primary cell 7 but also measures a different type of reference signal—the CSI-RS in this embodiment—for the extension carrier as S3. ¶ [0096]), and wherein the report indicates that the first measuring result is associated with the second measuring result in time (SI- See Fig. 13: the time domain configuration of the measurement window may contain all the RS (i.e., Reference Signals) for DRS based RRM measurement, such that UE assumes all the RSs for DRS based RRM measurement are within the measurement window. ¶ [0257]). Regarding claim 8; Sharma in view of Si teaches the UE wherein to generate the one or more reports, the processor is further configured to: receive a configuration message from the first base station, wherein the configuration message configures the processor to: generate a first report that includes the first measuring result; and generate a second report that includes the second measuring result (Sharma: the mobile communication device 3 not only measures the CRS of the component carrier used for the primary cell 7 but also measures a different type of reference signal—the CSI-RS in this embodiment—for the extension carrier as S3. ¶ [0096]), wherein the first report or the second report indicates that the first measuring result is associated with the second measuring result in time (SI- See Fig. 13: the time domain configuration of the measurement window may contain all the RS (i.e., Reference Signals) for DRS based RRM measurement, such that UE assumes all the RSs for DRS based RRM measurement are within the measurement window. ¶ [0257]).

Regarding claim 10; Sharma teaches the UE wherein the processor is further configured to: transmit a capability report to the first base station, wherein the capability report indicates that the UE is capable of receiving the first reference signal and the second reference signal during the measuring period simultaneously (Sharma: a more advanced multi-carrier capable terminal would be able to simultaneously use the multiple component carriers. ¶ [0003]). Regarding claim 11; Sharma teaches a method of operating a user equipment (UE) comprising: measuring a first reference signal (See Fig. 6: At step S3, the mobile communication device 3 not only measures the CRS of the component carrier (i.e., first reference signal) used for the primary cell 7. ¶ [0096]) and a second reference signal (See Fig. 6: Thus, the mobile communication device 3 measures a different type of reference signal (i.e., second reference signal)—the CSI-RS in this embodiment—for the extension carrier as S3. ¶ [0096]) during a measuring period to determine a first measuring result of the first reference signal and a second measuring result of the second reference signal (See Figs. 2 and 6: the measurement period for the measurement of the CSI-RS RSRP/RSRQ for the CSI-RS on the extension carrier is advantageously dependent on the timing parameter. ¶ [0083]); generating one or more reports that include the first measuring result and the second measuring result (See Fig. 6: @S4, reporting results of measurements performed on the reference signals of the first type for the first component carrier and results of measurements performed on the reference signals of the second type for the second component carrier; ¶ [0020] and ¶ [0096]), wherein the report indicate that the first measuring result is associated with the second measuring (See Fig. 6: @S4: the mobile device to generate and report an associated measurement report comprising the results of the measurements (in this embodiment values of RSRP and RSRQ) and send it to the base station 5-1 at S4. ¶ [0096]); and transmitting the one report to the first base station (See Fig. 6: @S4 the mobile device to generate and send an associated measurement report comprising the results of the measurements (in this embodiment values of RSRP and RSRQ) to the base station 5-1 at S4. ¶ [0096]). Sharma doesn’t explicitly state the measurement results are associated in time (domain) and using the two transceivers. However, SI further provides the measurement results are associated in time (domain) (SI- See Fig. 13: the time domain configuration of the measurement window may contain all the RS (i.e., Reference Signals) for DRS based RRM measurement, such that UE assumes all the RSs for DRS based RRM measurement are within the measurement window. ¶ [0257]) and using the two transceivers (SI- See Fig. 2: a UE can be configured at least two RMTCs for a cell, wherein a first RMTC is utilized for RSSI measurement of signals/channels from NR-U, and a second RMTC is utilized for RSSI measurement of signals/channels from co-existing RATs (e.g., Wi-Fi). ¶ [0320]). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to provide the measurement results are associated in time (domain) and using the two transceivers as taught by SI to have incorporated in the system of Sharma, so that it would provide to enhance the configuration of RMTC to address the utilization scenario of flexible numerology for the RSSI samples. SI: ¶ [0310]. [Office’s Note: Because of the alternative claim language such as “one or more”, only one of the alternative limitations has been analyzed by the examiner].
