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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 09/04/2026 has been entered. Remarks The present Office Action is in response to Applicant’s claim after final amendment filed on 08/11/2026.

Claims 41 and 42 recite, “A method performed by a User Equipment (UE), the method comprising: communicating with a communication apparatus; and receiving a first information element (IE) from the communication apparatus…” However, the current specification does not support the limitation. Claims 43 and 44 recite, “A User Equipment (UE) comprising: at least one memory; and at least one processor coupled to the at least one memory and configured to: receive a first information element (IE) from a communication apparatus…” However, the current specification does not support the limitation. Applicant is welcomed to point out to the part(s) of the specification that provides support for the limitation(s). Allowable Subject Matter Claim(s) 1-40 is/are allowed.

Therefore, claims 1-40 are considered novel and non-obvious, and allowed. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Response to Arguments Applicant’s arguments with respect to claim(s) 1-44 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion The prior art made of record and not relied upon is considered pertinent to Applicant’s disclosure. Dinan -US 20220110101 A1- disclose Secondary Cell In A Wireless Device And Wireless Network. Löhr et al. -US 20200053632 A1- disclose METHOD AND APPARATUS FOR APPLYING A CELL RESTRICTION CONFIGURATION. Dinan -US 20150373686 A1- disclose Carrier Grouping In Multicarrier Wireless Networks.
