Office Action

§112
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 . Response to Arguments Applicant’s arguments, see section II, with respect to claims 2-3, 12, 14, and 16 have been fully considered and are persuasive. The objection of claims 2-3, 12, 14, and 16 has been withdrawn. Applicant’s arguments, see section III, with respect to claims 1, 3, 8-10, 15, 18, and 20 have been fully considered and are persuasive. The double patenting rejection of claims 1, 3, 8-10, 15, 18, and 20 has been withdrawn. Applicant’s arguments, see section IV, with respect to claims 1, 3, 8-10, 13-15, and 20 have been fully considered and are persuasive. The rejection under 35 U.S.C. § 103 of claims 1, 3, 8-10, 13-15, and 20 has been withdrawn. Applicant’s arguments, see section V, with respect to claims 4-7, 9, 11-12, and 16-19 have been fully considered and are persuasive. The rejection under 35 U.S.C. § 103 of claims 4-7, 9, 11-12, and 16-19 has been withdrawn. Claim Objections Claim(s) 7 is/are objected to because of the following informalities: change “the received” in line 4 to “the one or more received”. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claim(s) 2, 5, and 16 is/are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Regarding claim 2, Applicant has amended claim 2 to now recite “the one or more reference signals are transmitted by the user equipment”. Applicant does not provide support for this amendment within the specification nor has the Examiner found support for this amendment within the specification. Regarding claim 5, Applicant has amended claim 5 to now recite “use the predicted future quality” “to adjust one or more radio links between the user equipment and a base node (apparently a base node is different from the base station)”. There is adjustment of the radio link between the user equipment and the base station and also adjustment of one or more radio links between the same user equipment and a base node, both of which depend on the predicted future quality. Applicant does not provide support for this amendment within the specification nor has the Examiner found support for this amendment within the specification. Regarding claim 16, in view of claim 15 reciting “modifying” “one or more characteristics of the radio link” (which is essentially adjusting the radio link), there is also additionally “…a node to adjust the radio link” (two adjustments/modification of the radio link done by apparently two different entities one of which is the node). Applicant does not provide support for this amendment within the specification nor has the Examiner found support for this amendment within the specification. Allowable Subject Matter Claim(s) 1, 3-4, 6-15, and 17-21 is/are allowed. The following is a statement of reasons for the indication of allowable subject matter: in view of Applicant’s arguments for the independent claims, the amendments made to the independent claims indicates the reason(s) the claims are patentable over the prior arts of record. Thus, examiner's statement of reason(s) for allowance is not necessary. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: US 20210376895 discloses a gNB sending reference signals to a UE, the UE predicts CSI at a future time using the received reference signals, and based on the predicted CSI adjust transmission parameters for transmission to the UE. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
