Office Action

§103
DETAILED ACTION This office action is a response to an application filed on 01/18/2024. Claims 1- 12 are pending for examination. Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Information Disclosure Statement The information disclosure statement (IDS) was filed. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Drawings The Examiner contends that the drawings submitted on 01/18/2024 are acceptable for examination proceedings. 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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103(a) 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 non-obviousness. Claims 1-12 are rejected under 35 U.S.C. 103 as being unpatentable over Novlan et al. (US 20220407671 A1), hereinafter “Novlan”; and in further view of Akl et al. (US 20210212126 A1), hereinafter “Akl. Regarding claim 1, Novlan teaches A communication control apparatus comprising at least one processor that performs: by an interference detector, detecting interference between a dynamic communication cell provided by a dynamic communication station to a communication device around it, and a surrounding communication cell around the dynamic communication station [Novlan: Figs. 2A- 2G; Par. 13;31- 33; 40- 42 teaches of IAB configuring of dynamic scheduling basis]. PNG media_image1.png 576 688 media_image1.png Greyscale However, Novlan does not teach by an interference reducer, implementing an interference reduction measure to reduce interference between the dynamic communication cell and the surrounding communication cell, in at least one of the dynamic communication cell and the surrounding communication cell Nevertheless, Akl, in the similar filed of endeavor, teaches by an interference reducer, implementing an interference reduction measure to reduce interference between the dynamic communication cell and the surrounding communication cell, in at least one of the dynamic communication cell and the surrounding communication cell [Akl: Fig. 6C; Par. 70- 76 teaches IAB node using interference measurement to reduce interferences between nodes and UEs]. PNG media_image2.png 606 502 media_image2.png Greyscale Thus it would have been obvious to one of ordinary skill at the time the invention was made to utilize the teachings of Akl for reducing interference between cells. One of ordinary skill in the art would be motivated to utilize the teachings of Akl in the Novlan system in order to provide interference reducing procedure [Akl: Abstract]. Regarding claim 2, the combined Novlan in view of Akl teaches all the limitations in the parent claim 1. Novlan in view of Akl further teaches wherein the dynamic communication station is switchable between an active state in which the dynamic communication cell is provided and an inactive state in which the dynamic communication cell is not provided [Novlan: Fig. 2G; Par. 47 teaches of node can switch activation indication and deactivation indication]. Regarding claim 3, the combined Novlan in view of Akl teaches all the limitations in the parent claim 1. Novlan in view of Akl further teaches the dynamic communication station is a moving communication station, and the dynamic communication cell is a moving communication cell [Novlan: See Fig. 2E]. Regarding claim 4, the combined Novlan in view of Akl teaches all the limitations in the parent claim 1. Novlan in view of Akl further teaches wherein the dynamic communication station is attached to a movable object [Akl: Fig. 4; MT-DU]. Regarding claim 5, the combined Novlan in view of Akl teaches all the limitations in the parent claim 1. Novlan in view of Akl further teaches wherein the interference detector detects interference between the dynamic communication cell and the surrounding communication cell, based on the communication measurement result by the dynamic communication station [Novlan: Figs. 2A- 2G; Par. 13;31- 33; 40- 42 teaches of IAB configuring of dynamic scheduling basis]. Regarding claim 6, the combined Novlan in view of Akl teaches all the limitations in the parent claim 5. Novlan in view of Akl further teaches the dynamic communication station is the IAB (Integrated Access and Backhaul) node comprising the MT (Mobile Termination) that functions as a communication device to a parent base station and the DU (Distributed Unit) that functions as a child base station to a communication device and provides the dynamic communication cell [Novlan: Fig; 5A- 5E; Par. 39- 42 teaches of parent node providing indications and resources to child nodes], and the interference detector detects interference between the dynamic communication cell and the surrounding communication cell, based on the communication measurement result by the IAB node provided from the MT to the parent base station [Novlan: Figs. 2F-2G]. Regarding claim 7, the combined Novlan in view of Akl teaches all the limitations in the parent claim 1. Novlan in view of Akl further teaches wherein the interference detector detects interference between the dynamic communication cell and the surrounding communication cell, based on the communication measurement result by a sensor around the dynamic communication station [Akl: Fig. 6C; Par. 70- 76 teaches IAB node using interference measurement to reduce interferences between nodes and UEs]. Regarding claim 8, the combined Novlan in view of Akl teaches all the limitations in the parent claim 1. Novlan in view of Akl further teaches wherein the interference reduction measure includes at least one of the following: changing the provision direction; changing the beam to be used; changing the antenna to be used; changing the frequency band to be used; and applying the inter-cell interference coordination (ICIC), in at least one of the dynamic communication cell and the surrounding communication cell [Akl: Fig. 6C; Par. 70- 76 teaches IAB node using interference measurement to reduce interferences between nodes and UEs]. Regarding claim 9, the combined Novlan in view of Akl teaches all the limitations in the parent claim 1. Novlan in view of Akl further teaches wherein the interference reducer implements at least one of the following as the interference reduction measure: disconnecting at least a portion of the communication devices currently connected to at least one of the dynamic communication cell and the surrounding communication cell; switching at least a portion of either the dynamic communication cell or the surrounding communication cell to an inactive state; and transitioning at least a portion of the communication devices currently connected to one of the dynamic communication cell and the surrounding communication cell to the other communication cell [Akl: Par. 74 teaches of IAB nodes perform interference coordination by which nodes to yield when there is an interference in the communication system]. Regarding claim 10, the combined Novlan in view of Akl teaches all the limitations in the parent claim 1. Novlan in view of Akl further teaches wherein the interference reducer implements the interference reduction measure in the dynamic communication cell [Akl: Figs. 6A-6C; Par. 71- 78 teaches of different interference scenarios of IAB nodes/ interference reducer perform signal measurements to reduce interferences between nodes and UEs]. Regarding claim 11, the claims is interpreted and rejected for the same reason as set forth for claim 1. Regarding claim 12, Novlan teaches A computer-readable medium storing a communication control program causing a computer to perform [Novlan: Abstract]: detecting interference between a dynamic communication cell provided by a dynamic communication station to a communication device around it, and a surrounding communication cell around the dynamic communication station [Novlan: Figs. 2A- 2G; Par. 13;31- 33; 40- 42 teaches of IAB configuring of dynamic scheduling basis]. PNG media_image1.png 576 688 media_image1.png Greyscale However, Novlan does not teach implementing an interference reduction measure to reduce interference between the dynamic communication cell and the surrounding communication cell, in at least one of the dynamic communication cell and the surrounding communication cell. Nevertheless, Akl, in the similar filed of endeavor, teaches implementing an interference reduction measure to reduce interference between the dynamic communication cell and the surrounding communication cell, in at least one of the dynamic communication cell and the surrounding communication cell [Akl: Fig. 6C; Par. 70- 76 teaches IAB node using interference measurement to reduce interferences between nodes and UEs]. PNG media_image2.png 606 502 media_image2.png Greyscale Thus it would have been obvious to one of ordinary skill at the time the invention was made to utilize the teachings of Akl for reducing interference between cells. One of ordinary skill in the art would be motivated to utilize the teachings of Akl in the Novlan system in order to provide interference reducing procedure [Akl: Abstract].
