Response to Arguments
Applicant's arguments filed August 26, 2026 have been fully considered but they are not persuasive.
The argument features Tripathi does not disclose wherein an LTM candidate NTN cell, of the one or more LTM candidate NTN cells, is associated with multiple beams, and the RRC reconfiguration message includes beam identifiers of the multiple beams. At least one beam identifier, of the beam identifiers, associated with a corresponding beam of the multiple beams of the LTM candidate NTN cell.
The examiner respectfully disagrees with the applicant’s statement and asserts that Tripathi discloses the features of the amended independent claims “The NTN type may include GEO, LEO with fixed-earth beams, or LEO with moving beams. The information regarding information classification may include cell/beam specific information…” (par. 87, lines 7-11) “The gNB/eNB makes a handover decision, gets the approval of the target gNB/eNB and sends a handover command to the UE…in the form of an RRC message such as RRC Reconfiguration.” (par. 142, lines 3-6) “the gNB…chooses a candidate set of triggering quantities, trigger-combining methods, reporting quantities, and the handover decision-making approach, which are optimal for a given NTN Type.” (par. 263, lines 1-5) “…the gNB may select a handover approach that makes a handover decision when the UE near the cell edge when the NTN Type is “Earth-moving cells with moving beams.” (par. 263, lines 16-18)
In view of the above, the rejection using Guo and Tripathi is maintained as repeated below.

It is an object of Guo’s invention to provide a method for inter-cell mobility. It is an object of Tripathi’s invention to provide a method for handover signaling. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of Guo by including NTN cells, as taught by Tripathi, for the purpose of enhancing a user’s experience in a telecommunications network.
Consider claim 17, as applied in claim 16; Tripathi discloses the RRC reconfiguration message indicates a plurality of groups associated with a plurality of LTM candidate NTN cells including the one or more LTM candidate NTN cells (par. 107; par. 129, lines 7-12; par. 142, lines 1-6; par. 259).
Consider claim 18, as applied in claim 16; Guo discloses the indication to perform LTM is specific to a user equipment (UE) (par. 434, lines 4-10), or the indication to perform LTM is associated with a plurality of UEs including the UE.
Consider claim 19, as applied in claim 18; Tripathi discloses the RRC reconfiguration message indicates a group identifier associated with the plurality of UEs [e.g. via the groupcast/multicast (par. 107)].
Consider claim 20, as applied in claim 18; Tripathi discloses the indication to perform LTM indicates a group identifier associated with the plurality of UEs [e.g. via the groupcast/multicast (par. 107; par. 141, lines 4-8)].
Conclusion
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. In the event a first reply is filed within
TWO MONTHS of the mailing date of this final action and the advisory action is not
