As to Claim 20. Hasanzadezonuzy discloses the control unit of claim 18, wherein the processor is further configured to [Sections 0091, 0199]: control handover of a UE between a first small cell radio access point and the macro base station. [See Claim 6 because both claims have similar subject matter therefore similar rejection applies herein].
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 for establishing a background for determining obviousness under 35 U.S.C. 103 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 nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
2. Claims 3, 10, and 17 are rejected under 35 U.S.C. 103 as being unpatentable over
HASANZADEZONUZY et al. US 20250008404 hereafter Hasanzadezonuzy in view of LEROUX et al. US 20180376380 hereafter Leroux.
As to Claim 3. Hasanzadezonuzy discloses the cellular communication system of claim 1 [i.e. 3GPP 4G LTE, 5G, or 6G, see 0049], wherein the CU is configured to coordinate between two or more of the small cell radio access points [i.e. Pico network nodes] with overlapping cell coverages to [Sections 0033, 0055, 0087: Multiple RAT/cells can have overlapping spectrum usage. Various different types of network nodes transmit at different power levels, serve different coverage areas, and/or have different impacts on interference in the wireless communication network; for example, macro network nodes have a high transmit power level whereas pico network nodes have lower transmit power levels. The CU perform network control and signaling]
Although Hasanzadezonuzy discloses interference between network nodes (i.e. small access point/Pico network node) in coverage areas, it is silent on ICIC thus does not explicitly state implement Inter-Cell Interference Coordination (ICIC) to reduce signal interference between the two or more small cell radio access points.
However, Leroux teaches implement Inter-Cell Interference Coordination (ICIC) [Sections 0120, 0145: Capabilities including inter-cell interference coordination (ICIC). At the CU, the interference information is centralized and the CU establishes a joint ICIC optimization strategy] to reduce signal interference between the two or more small cell radio access points [Figs. 2-6, Sections 0091, 0095, 0119, 0171: At least one of optimization capability, which supposes that the CU is in charge of managing and minimizing (i.e. reduce) interference. CU deal with mobility, in the same way that different cells connectivity take into account the type (pico/small/macro) or coverage region of a cell. Coverage information enable CU to evaluate interference. The eNB (CU, see 172) would control a number of possibly overlapping cells with different frequencies; small cell deployment with DC could enable handover UEs from small cell to small cell, while keeping a macro cell active].
Therefore it would have been obvious before the effective filing date of the invention to have combined the methods of Hasanzadezonuzy relating to CU performing network management/control, the pico/small cells/network nodes or small access points have overlapping coverages and impacts interference with the teaching of Leroux relating to the CU manage and evaluate interference of different small cells or coverage region and use ICIC strategy in order to minimize or reduce interference. By combining the methods/systems, the CU/control network node can manage interference in the network using ICIC thereby minimizing or reducing signal interference in the system in order to provide optimization in communication as suggested by Leroux.
As to Claim 10. The method of claim 8, wherein the CU coordinates between two or more of the small cell radio access points with overlapping cell coverage to implement Inter-Cell Interference Coordination (ICIC) to reduce signal interference between the two or more small cell radio access points [See Claim 3 because both claims have similar subject matter therefore similar rejection applies herein].
As to Claim 17. Hasanzadezonuzy discloses the control unit of claim 15, wherein the processor is further configured to [Sections 0091, 0199]: coordinate between two or more of the small cell radio access points with overlapping cell coverages to implement Inter-Cell Interference Coordination (ICIC) to reduce signal interference between the two or more small cell radio access points. [See Claim 3 because both claims have similar subject matter therefore similar rejection applies herein].
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Kim et al. US 20190342809 and Xu et al. US 20220232433
Furthermore, each additional prior arts cited on PTO-892 but not applied in rejection contains a disclosed description related to the claimed subject matter found either in the Figures, description summary and/or disclosure.
