Office Action

§102
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 . Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1, 20 and 21 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Sebire et al. (US 2023/0276324 A1 with effective filing date of 8/6/2020 based on provisional 62/706253). Sebire teaches cell reselection-related Information associated with network slice (Figure 6). With respect to the claims, references to the prior art appear in parenthesis. Claims 1. (Currently Amended) A method for slice-based cell reselection (Sebire et al., US 2023/0276324 A1) , performed by user equipment, and comprising: obtaining network slice information (Figure 6, step 3. Cell reselection-related Information: Slice Information for frequency bands…) and slice-based cell reselection information (Figure 6, step 4. Cell reselection-related Information: RSRP/RSRQ offsets for network slices 1 and 2) ; deriving a first priority frequency for slice-based cell reselection according to the network slice information and the slice-based cell reselection information (Slice-specific cell reselection-related priority Information indicating a priority of a cell reselection of specific slices in paragraph 0109, where the specific slices corresponds to specific frequency bands in Figure 6, step 5) ; and performing cell reselection on the first priority frequency for slice-based cell reselection, and identifying a suitable cell for camping on the first priority frequency for slice-based cell reselection (Figure 6, step5. The UE performs cell reselection evaluation and uses RSRP/RSRQ offset for network slice 1 for freq. band 1…, where the UE camps on the particular frequency on the cell in paragraph 0103) . 20. (Currently Amended) An electronic device (Sebire et al., US 2023/0276324 A1), comprising: one or more processors; and a storage apparatus, configured to store one or more programs, wherein when the one or more programs are executed by the one or more processors, the one or more processors are directed to implement a method for slice-based cell reselection, comprising: obtaining network slice information (Figure 6, step 3. Cell reselection-related Information: Slice Information for frequency bands…) and slice-based cell reselection information (Figure 6, step 4. Cell reselection-related Information: RSRP/RSRQ offsets for network slices 1 and 2); deriving a first priority frequency for slice-based cell reselection according to the network slice information and the slice-based cell reselection information (Slice-specific cell reselection-related priority Information indicating a priority of a cell reselection of specific slices in paragraph 0109, where the specific slices corresponds to specific frequency bands in Figure 6, step 5); and performing cell reselection on the first priority frequency for slice-based cell reselection, and identifying a suitable cell for camping on the first priority frequency for slice-based cell reselection (Figure 6, step5. The UE performs cell reselection evaluation and uses RSRP/RSRQ offset for network slice 1 for freq. band 1…, where the UE camps on the particular frequency on the cell in paragraph 0103) . 21. (Currently Amended) A non-transitory computer-readable storage medium(Sebire et al., US 2023/0276324 A1), wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, a method for slice-based cell reselection is implemented, the method comprising: obtaining network slice information (Figure 6, step 3. Cell reselection-related Information: Slice Information for frequency bands…) and slice-based cell reselection information (Figure 6, step 4. Cell reselection-related Information: RSRP/RSRQ offsets for network slices 1 and 2) ; deriving a first priority frequency for slice-based cell reselection according to the network slice information and the slice-based cell reselection information (Slice-specific cell reselection-related priority Information indicating a priority of a cell reselection of specific slices in paragraph 0109, where the specific slices corresponds to specific frequency bands in Figure 6, step 5); and performing cell reselection on the first priority frequency for slice-based cell reselection, and identifying a suitable cell for camping on the first priority frequency for slice- based cell reselection (Figure 6, step5. The UE performs cell reselection evaluation and uses RSRP/RSRQ offset for network slice 1 for freq. band 1…, where the UE camps on the particular frequency on the cell in paragraph 0103) . Allowable Subject Matter Claims 2-18 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: the prior art of record do not further anticipate or make obvious the deriving of candidate frequencies and the selection of candidate frequencies based on the recited criteria.
