Office Action

§101 §102 §103
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. Information Disclosure Statement The information disclosure statement (IDS) submitted on 10 / 05 /202 3 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Rejections - 35 USC § 101 The claims 60 and 61 are drawn to a “computer-readable storage medium” comprising stored data. The Specification mentioned in paragraph [¶ 0251 and 0258] "the computer-readable storage medium may be a transitory or a non-transitory computer-readable storage medium". Thus, applying the broadest reasonable interpretation in light of the Specification and taking into account the meaning of the words in their ordinary usage as they would be understood by one of ordinary skill in the art (MPEP §2111.01), the claim as a whole covers a transitory signal , as such, does not fall within the definition of a process, machine, manufacture, or composition of matter (MPEP §2106.01). Therefore, claims 60 and 61 are directed towards non-statutory subject matter (See MPEP section 2106, Seventh Edition, Revision No. dated February 2000, at page 2100-10 and 2100-11). Other dependent claims, which are not specifically cited above are also rejected because of the deficiencies of their respective parent claims. Examiner’s comment : A claim drawn to such a computer readable medium that covers both transitory and non-transitory embodiments may be amended to narrow the claim to cover only statutory embodiments to avoid a rejection under 35 US.C. § 101 by adding the limitation “non-transitory” to the claim term ( Kappos memo dated January 26, 2010 available at http://www.uspto.gov/patents/law/notices/101_crm_20100127.pdf ). Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim s FILLIN "Insert the claim numbers which are under rejection." \d "[ 1 ]" 35-41, 43, 45-49, and 51-61 are rejected under 35 U.S.C. 102 (a)( 1 ) as being FILLIN "Insert either—clearly anticipated—or—anticipated—with an explanation at the end of the paragraph." \d "[ 3 ]" anticipated by FILLIN "Insert the prior art relied upon." \d "[ 4 ]" CAROLINE JACTAT ( GB-2574875-A ), hereinafter, Jactat .

Therefore, the node can propose to update the radio resources list mapping to DRB identity 2 (DRBI 2) instead of DRBI 1 and 5. The node includes DRBI 2 in the Confirmation message. If the node determines that none of the DRBI fulfils the target QoS of PDB=10 ms , then the Reject message is sent back to the sender of the QoS Topology Inquiry."

The reply sent at Step 3’a may comprise QoS information, e.g. a value of at least one QoS parameter. The QoS information may indicate the effect of IAB node 2 on the QoS budget. For example, if IAB node 2 incurs a PDB of 2ms, the QoS information sent at step 3’a may indicate that value , a remaining QoS budget after subtracting that value, or a cumulative total of the effect of IAB node 2 and preceding nodes along the path."

Applicant’s attention is directed to the rejection of claim 35 . Claim 60 is rejected under the same rational as claim 35 . Claim 61 (CRM) is exactly the same as Claim 45 (method second node) and is rejected above. Applicant’s attention is directed to the rejection of claim 45 . Claim 61 is rejected under the same rational as claim 45 . 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. Claim 42 is rejected under 35 U.S.C. 103 as being unpatentable over Jactat in view of 3GPP TSG-RAN WG2 Meeting #113e; R2-2100592; agenda Item: Probably 8.4.3; Source: Qualcomm Incorporated , 2021-01-13, hereinafter, R2-2100592 , disclosed in PCT report ). Regarding Claim 42, Jactat discloses, the method according to claim 40. Jactat doesn’t explicitly discloses, wherein performing the action comprises one or more of the following: initiating Inter central unit (CU) load sharing; identifying a potential new parent Integrated Access Backhaul (IAB) node under a different CU: selecting a CU or Cell to perform Load Sharing or migration. R2-2100592 in related art discloses, wherein performing the action comprises one or more of the following: initiating Inter central unit (CU) load sharing; identifying a potential new parent Integrated Access Backhaul (IAB) node under a different CU: selecting a CU or Cell to perform Load Sharing or migration (Target IAB DU may at least pre-configure the BH RLC channels with non GBR QoS requirements. For the BH RLC channels with GBR QoS requirement, target IAB DU may not accept all of them if they require a large data volume. For the intra-donor CU migration, the donor CU has full knowledge of the QoS requirement of the BH RLC channels/UE DRBs of the migration IAB node, descendant IAB nodes and UEs, it can also reconfigure the BH RLC channels after the migration IAB node completes the CHO procedure. [¶ Page 27]). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine the idea of Jactat with the idea of selecting a CU or Cell to perform Load Sharing or migration as disclosed by R2-2100592 . The rationale for performing this is to manage network traffic and optimize resource allocation within an IAB network. Claim s 44 , and 50 are rejected under 35 U.S.C. 103 as being unpatentable over Jactat in view of , Xu et al. (US 20230328625 A1, hereinafter, Xu). Regarding Claim 44, Jactat discloses, the method according to claim 35. Jactat doesn’t explicitly discloses, wherein the first radio network node is a first central unit and the second radio network node is a second central unit. Xu in related art relates, wherein the first radio network node is a first central unit and the second radio network node is a second central unit ( Fig, 2a, " At block 410, the first CU-CP 213 transmits, to a second CU-CP 214 , a request to transfer target traffic of an interface between a first IAB donor 210 and an JAB node 240 via a DU 222 of the second IAB donor 220. The request comprises first information of the target traffic." [¶ 0097], see also, " At block 510, the second CU-CP 223 receives, from a first CU-CP 213 , a request to transfer target traffic of an interface between a first IAB donor 210 and an JAB node 240 via a DU 222 of the second IAB donor 220. The request comprises first information of the target traffic." [¶ 0105]). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to combine the idea of Jactat with the idea of having first and second radio network node connected to two separate CU as disclosed by Xu . The rationale for having this multi-node setups, where a first network node (such as a first CU) may obtain congestion indications from a second node (like a second CU) to adjust data transmission rates for downlink congestion control. Claim 50 (method second node) is exactly the same as Claim 44 (method first node) and is rejected above. Applicant’s attention is directed to the rejection of claim 44 . Claim 50 is rejected under the same rational as claim 44 . Conclusion References cited but not used: LUO; Jianghong et al.
