Office Action

§103
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 . Art Unit- Location The Art Unit location of your application in the USPTO has changed. To aid in correlating any papers for this application, all further correspondence regarding this application should be directed to Art Unit 2642. 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 12/22/2025 has been entered. Claim Rejections - 35 USC § 103 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. 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 of this title, 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(a) 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 under 35 U.S.C. 103(a), the examiner presumes that the subject matter of the various claims was commonly owned at the time any inventions covered therein were made absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and invention dates of each claim that was not commonly owned at the time a later invention was made in order for the examiner to consider the applicability of 35 U.S.C. 103(c) and potential 35 U.S.C. 102(e), (f) or (g) prior art under 35 U.S.C. 103(a) Claims 1, 3-4, 8-10, 12-13 and 17-18 are rejected under 35 U.S.C. 103 as being un-patentable over BI et al Patent Application No. :( US 2021/0289463 A1) hereinafter referred as BI, in view of Lin et al US Patent Application No.:( US 2020/0059847 A1) hereinafter referred as Lin. For claim 1, BI teaches a wireless communication method, comprising: sending, by a wireless communication device to a wireless communication node, a message to update a downlink reference signal (paragraph [0034], lines 1-10), wherein the downlink reference signal is configured to position a user equipment (UE) (paragraph [0035], lines 1-10). However , BI discloses all the subject matter of the claimed invention with the exemption of the requesting, by the wireless communication device, to terminate a transmission of an on going downlink reference signal as recited in claim 1. LIn from the same or analogous art teaches the terminal device may stop measuring the downlink reference signal, that is, cancel measurement on the downlink reference signal, to reduce operations and computation of the terminal device by terminating the measurement process. Alternatively, the terminal device continues measuring the downlink reference signal even if the terminal device receives the handover command sent by the base station (paragraph [0151], lines 1-13). Therefore, it would have been obvious for the person of ordinary skill in the art at the time of filling to use the requesting, by the wireless communication device, to terminate a transmission of an on going downlink reference signal as taught by LIn into the uplink signal transmission method and apparatus of BI. The requesting, by the wireless communication device, to terminate a transmission of an on going downlink reference signal can be modify/implemented by combining the requesting, by the wireless communication device, to terminate a transmission of an on going downlink reference signal with the device. This process is implemented as a hardware solution or as firmware solutions of LIn into the uplink signal transmission method and apparatus of BI. As disclosed in LIn, the motivation for the combination would be to use the requesting, by the wireless communication device, to terminate a transmission of an on going downlink reference signal to manage more efficiently the communication, becoming more efficient and reliable. For claim 3, BI teaches a wireless communication method, wherein the message further indicates at least one of: (i) one or more positioning node IDs; or ( ii) one or more downlink positioning reference signal resource set IDs (paragraph [0017], lines 13-23) and (paragraph [0171], lines 1-10). For claim 4, BI teaches a wireless communication method, wherein sending the message further comprises: requesting, by the wireless communication device, to be activated or triggered by the wireless communication node to semi-persistently receive the downlink reference signal that has been configured (301-304 fig. 3) (paragraph [0044]-[0045], lines 1-19); and indicating, by the wireless communication device in the message, which duration is selected for receiving the downlink reference signal (paragraph [0020], lines 1-16) and (paragraph [0085], lines 1-17). For claim 8, BI teaches a wireless communication device, comprising: at least one processor configured to: send, via a transmitter to a wireless communication node, a message to update a downlink reference signal (paragraph [0034], lines 1-10), wherein the downlink reference signal is configured to position a user equipment (UE) (paragraph [0035], lines 1-10). For claim 9, BI teaches a wireless communication node, comprising: at least one processor configured to:receive, via a receiver from a wireless communication device, a message to update a downlink reference signal (paragraph [0034], lines 1-10), wherein the downlink reference signal is configured to position a user equipment (UE) (paragraph [0035], lines 1-10). However , BI discloses all the subject matter of the claimed invention with the exemption of the request to terminate a transmission of an on-going downlink reference signal as recited in claim 9. LIn from the same or analogous art teaches the terminal device may stop measuring the downlink reference signal, that is, cancel measurement on the downlink reference signal, to reduce operations and computation of the terminal device by terminating the measurement process. Alternatively, the terminal device continues measuring the downlink reference signal even if the terminal device receives the handover command sent by the base station (paragraph [0151], lines 1-13). Therefore, it would have been obvious for the person of ordinary skill in the art at the time of filling to use the request to terminate a transmission of an on-going downlink reference signal as taught by LIn into the uplink signal transmission method and apparatus of BI. The request to terminate a transmission of an on-going downlink reference signal can be modify/implemented by combining the request to terminate a transmission of an on-going downlink reference signal with the device. This process is implemented as a hardware solution or as firmware solutions of LIn into the uplink signal transmission method and apparatus of BI. As disclosed in LIn, the motivation for the combination would be to use the requesting, by the wireless communication device, to terminate a transmission of an on going downlink reference signal to manage more efficiently the communication, becoming more efficient and reliable. For claim 10, BI teaches a wireless communication method, comprising: receiving, by a wireless communication node from a wireless communication device, a message to update a downlink reference signal (paragraph [0034], lines 1-10), wherein the downlink reference signal is configured to position a user equipment (UE) (paragraph [0035], lines 1-10). However , BI discloses all the subject matter of the claimed invention with the exemption of the receiving a request from the wireless communication device to terminate a transmission of an on-going downlink reference signal as recited in claim 10. LIn from the same or analogous art teaches the terminal device may stop measuring the downlink reference signal, that is, cancel measurement on the downlink reference signal, to reduce operations and computation of the terminal device by terminating the measurement process. Alternatively, the terminal device continues measuring the downlink reference signal even if the terminal device receives the handover command sent by the base station (paragraph [0151], lines 1-13). Therefore, it would have been obvious for the person of ordinary skill in the art at the time of filling to use the receiving a request from the wireless communication device to terminate a transmission of an on-going downlink reference signal as taught by LIn into the uplink signal transmission method and apparatus of BI. The receiving a request from the wireless communication device to terminate a transmission of an on-going downlink reference signal can be modify/implemented by combining the receiving a request from the wireless communication device to terminate a transmission of an on-going downlink reference signal with the device. This process is implemented as a hardware solution or as firmware solutions of LIn into the uplink signal transmission method and apparatus of BI. As disclosed in LIn, the motivation for the combination would be to use the requesting, by the wireless communication device, to terminate a transmission of an on going downlink reference signal to manage more efficiently the communication, becoming more efficient and reliable. For claim 12, BI teaches a wireless communication method, wherein the message further indicates at least one of: (i) one or more positioning node IDs; or (ii )one or more downlink positioning reference signal resource set IDs (paragraph [0017], lines 13-23) and (paragraph [0171], lines 1-10).
