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 .
Claims 1-20 are pending.
Claim Rejections - 35 USC § 103
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.
Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Paterson et al, application no. 2021/0259038, hereinafter known as Paterson in view of 3GPP TSG-RAN2 Meeting #120 R2-2212069 Toulouse, France, 14 - 18 November 2022 8.4.2.2 Agenda Item: Huawei, HiSilicon Source: Configuration of candidate target configurations (pre-configurations) for LTM hereinafter known as Huawei.
As to claim 1, Paterson discloses a first network node for wireless communication, comprising: a memory; and one or more processors, coupled to the memory (Paterson, figure 4, CU and DU of the art with controller and memory), configured to: receive, from a second network node, an indication of a reference layer 1/layer 2 triggered mobility (LTM) configuration (Paterson, [0093]-[0095], figure 7, step S701, triggered mobility determination at first node (CU), step S703, sending to first node (target DU) by second node (en-gNB-cu) UE context setup request); identify, based at least in part on the reference configuration, one or more candidate cell configurations associated with one or more candidate cells for an UE context setup procedure (Paterson, [0039]-[0040], target DU determining UE context for triggered mobility with delta or full configuration determination); and transmit, to the second network node, an indication of the one or more candidate cell configurations (Paterson, [0093]-[0095], S704, sending by first node (target DU) to second node (en-gNB-CU), UE context response with full or partial configuration). Paterson does not expressly disclose however Huawei disclose triggered mobility being layer 1/layer 2 triggered mobility (LTM) procedure (Huawei, section 2: layer 1/layer 2 triggered mobility setup procedure between CU and target DU with delta or full configurations).
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 teachings of Paterson to include the limitations of triggered mobility being layer 1/layer 2 triggered mobility (LTM) procedure as taught by Huawei. Use of LTM procedure allow faster setup communication context setup for UE with less signaling overhead.
As to claim 2, Paterson discloses wherein the first network node is a distributed unit of a network entity, and wherein the second network node is a centralized unit of a network entity (Paterson, figure 7 and 8, target DU as first node and en-gNB-CU are second node).
As to claim 3, Paterson and Huawei disclose the first network node of claim 1. Paterson does not disclose however Huawei discloses wherein the one or more processors are further configured to receive, from the second network node, an indication of source cell information associated with a source cell of a user equipment (UE), wherein identifying the one or more candidate cell configurations is further based at least in part on the source cell information (Huawei, page 2, section 2.2, delta configuration LTM, where UE configuration for target candidate cell uses pre-configuration information based on source cell information).
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 teachings of Paterson to include the limitations of wherein the one or more processors are further configured to receive, from the second network node, an indication of source cell information associated with a source cell of a user equipment (UE), wherein identifying the one or more candidate cell configurations is further based at least in part on the source cell information as taught by Huawei. Source cell information used for candidate cell configuration provides delta configuration information thereby speeding up bearer set up and reducing signaling overhead.
As to claim 4, Paterson discloses wherein the one or more candidate cell configurations are associated with a candidate cell group configuration (Paterson, [0039]-[0040], target DU (candidate cell) providing configurations information to CU).
As to claim 5, Paterson discloses wherein the one or more candidate cell configurations are associated with one or more delta configurations with respect to the reference LTM configuration (Paterson, [0039]-[0040], target DU (candidate cell) providing configurations information to CU, where the configuration is delta or full configuration).
As to claim 6, Paterson discloses wherein the one or more processors are further configured to transmit, to the second network node, an indication that the one or more candidate cell configurations are associated with the one or more delta configurations (Paterson, [0093]-[0095], S704, sending by first node target DU to second node en-gNB-CU, UE context response with full or partial configuration).
As to claim 7, Paterson discloses wherein the one or more candidate cell configurations are associated with one or more full configurations (Paterson, [0039]-[0040], target DU (candidate cell) providing configurations information to CU, where the configuration is delta or full configuration).
As to claim 8, Paterson discloses wherein the one or more processors are further configured to transmit, to the second network node, an indication that the one or more candidate cell configurations are associated with the one or more full configurations (Paterson, [0039]-[0040], target DU (candidate cell) providing configurations information to CU, where the configuration is delta or full configuration; [0093]-[0095], S704, sending by first node target DU to second node en-gNB-CU, UE context response with full or partial configuration).
As to claims 9-16, the claims are rejected as applied to claims 1-8 respectively above by Paterson in view of Huawei.
As to claims 17-20, the claims are rejected as applied to claims 1, 4, 5 and 7 respectively above by Paterson in view of Huawei.
