Office Action

§103 §112
DETAILED ACTION This office action is a response to an application filed on 12/19/2023. Claims 1- 20 are pending for examination. Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Information Disclosure Statement The information disclosure statement (IDS) was filed. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application. Drawings The Examiner contends that the drawings submitted on 12/19/2023 are acceptable for examination proceedings. 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 4,5, 11, 12, and 18 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. The term “at least part of characteristics of the first function” in claims 4,5,11,12 and 18 is a relative term which renders the claim indefinite. The term is not defined by the claim and it fails to specify which characteristics or how much of the characteristics of the function is specified. The specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. 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 (i.e., changing from AIA to pre-AIA ) 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, 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 non-obviousness. Claims 1- 20 are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. (US 20180262938 A1), hereinafter “Liu”; and in further view of Qi et al. (US 20210234662 A1), hereinafter “Qi”. Regarding claim 1, Liu teaches A first node for wireless communications, characterized in comprising [Liu: Abstract teaches method for signaling CSI and reference signals by UE]: a first processor, which receives a reference signal in a first reference signal resource sub-pool, the first reference signal resource sub-pool comprising at least one reference signal resource [Liu: Fig. 5; Par. 64- 70 teaches receive one or more values of CSI-RS resources where index indicated CQI report configurations], and determines a first function according to the receiving behavior in the first reference signal resource sub-pool [Liu: Par. 64- 68 teaches perform matching and generated reports based on the values of the indexes]; and a first transmitter, which transmits a first information block, the first information block being used to determine the first function [Liu: Fig. 6; Par. 666 teaches send CSI report]; the first processor, which receives a second information block, the second information block being used to determine whether a target reference signal resource is associated with the first function [Liu: Par. 64- 68 teaches of receiving and matching/ determining of CQI report values and transmitting CSI report with lowest value of collision and type of priority]; PNG media_image1.png 578 446 media_image1.png Greyscale However, Liu does not teach wherein the first transmitter, which transmits a third information block, the third information block indicating a first compressed CSI, the first compressed CSI being an input to the first function for generating a first CSI. Nevertheless, Qi, in the similar filed of endeavor, teaches the first transmitter, which transmits a third information block, the third information block indicating a first compressed CSI, the first compressed CSI being an input to the first function for generating a first CSI [Qi: Fig. 3A, 3B; Par. 72- 75 teaches of comparing compressed CSI reports, dividing into the groups/blocks and generating single CSI report based on that]. PNG media_image2.png 628 418 media_image2.png Greyscale Thus it would have been obvious to one of ordinary skill at the time the invention was made to utilize the teachings of QI for compressed CSI reporting with wireless devices. One of ordinary skill in the art would be motivated to utilize the teachings of QI in the Liu system in order to efficiently compressing CSI feedback signaling [Qi: Par. 7]. Regarding claim 2, the combined Liu in view of Qi teaches all the limitations in the parent claim 1. Liu in view of Qi further teaches characterized in that the first processor determines a second function according to the receiving behavior in the first reference signal resource sub-pool; wherein an output by the second function comprises the first compressed CSI [QI; par. 72 -75 further teaches comparing the compressed CSI reports based on the correlation and reporting ang generating of single CSI report out of different groups]. Regarding claim 3, the combined Liu in view of Qi teaches all the limitations in the parent claim 1. Liu in view of Qi further teaches characterized in that the first transmitter transmits a fourth information block, the fourth information block indicating a second compressed CSI, the second compressed CSI being an input to a first enhancement function for generating a second CSI; wherein the first function is used for generating the first enhancement function; the second information block is used to determine whether the target reference signal resource is associated with the first enhancement function [See Liu; Par. 64- 68 and QI Figs. 3A-3B]. Regarding claim 4, the combined Liu in view of Qi teaches all the limitations in the parent claim 1. Liu in view of Qi further teaches characterized in that the second information block indicates at least part of characteristics of the first function [Liu: Par. 64- 68 teaches indicating values of the indexes]. Regarding claim 5, the combined Liu in view of Qi teaches all the limitations in the parent claim 1. Liu in view of Qi further teaches characterized in that the second information block indicates at least part of characteristics of the first enhancement function [Liu: Fig. 5]. Regarding claim 6, the combined Liu in view of Qi teaches all the limitations in the parent claim 1. Liu in view of Qi further teaches characterized in that the second information block comprises a first transmission configuration state, the first transmission configuration state implicitly indicating whether the target reference signal resource is associated with the first function [Liu: Par. 64- 66 teaches measurements of values of each indexes indicating corresponding CSI-RS resources]. Regarding claim 7, the combined Liu in view of Qi teaches all the limitations in the parent claim 1. Liu in view of Qi further teaches characterized in that the first transmitter transmits a fifth information block, the fifth information block indicating whether the target reference signal resource is suitable to be associated with the first function [Liu: Par. 64- 66]. Regarding claim 8, Liu teaches A second node for wireless communications, characterized in comprising: [Liu: Abstract teaches method for signaling CSI and reference signals by UE]: a second transmitter, which transmits a reference signal in a first reference signal resource sub-pool, the first reference signal resource sub-pool comprising at least one reference signal resource [Liu: Fig. 5; Par. 64- 70 teaches receive one or more values of CSI-RS resources where index indicated CQI report configurations], and a target receiver of the first reference signal resource sub-pool determining a first function according to a receiving behavior in the first reference signal resource sub-pool [Liu: Par. 64- 68 teaches perform matching and generated reports based on the values of the indexes]; and a first receiver, which receives a first information block, the first information block being used to determine the first function [Liu: Fig. 6; Par. 666 teaches send CSI report]; the second transmitter, which transmits a second information block, the second information block being used to determine whether a target reference signal resource is associated with the first function [Liu: Par. 64- 68 teaches of receiving and matching/ determining of CQI report values and transmitting CSI report with lowest value of collision and type of priority]; PNG media_image1.png 578 446 media_image1.png Greyscale However, Liu does not teach the first receiver, which receives a third information block, the third information block indicating a first compressed CSI, the first compressed CSI being an input to the first function for generating a first CSI. Nevertheless, Qi, in the similar filed of endeavor, teaches the first receiver, which receives a third information block, the third information block indicating a first compressed CSI, the first compressed CSI being an input to the first function for generating a first CSI [Qi: Fig. 3A, 3B; Par. 72- 75 teaches of comparing compressed CSI reports, dividing into the groups/blocks and generating single CSI report based on that]. PNG media_image2.png 628 418 media_image2.png Greyscale Thus it would have been obvious to one of ordinary skill at the time the invention was made to utilize the teachings of QI for compressed CSI reporting with wireless devices. One of ordinary skill in the art would be motivated to utilize the teachings of QI in the Liu system in order to efficiently compressing CSI feedback signaling [Qi: Par. 7].
