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 .
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.
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.
Claims 1,3,4, 21,and 23 are rejected under 35 U.S.C. 103 as being unpatentable over ZTE ( ON UE Adaptation to Maximum Number of MMO Layers) in view of Khoshnevisan et al. (2023/0344578).
For claims 1,3,4, 21,and 23 , ZTE ( ON UE Adaptation to Maximum Number of MMO Layers) discloses a method of wireless communication at a user equipment (UE) (sections 1-3): In this contribution, the aspects of CSI reporting when UE adapts to maximum number of MIMO layer are discussed. When adapting to DL maximum number of MIMO layers, UE can save considerable power consumption. If the rank indicator restriction is not properly configured, the UE might traverse several ranks to find a proper value for a CSI report (e.g., from rank one to rank two, then to rank three, then to rank four). This will not only consume more power, but also cause more computation complexity. An appropriate configuration on rank indicator restriction can further reduce power consumption for CSI measurement (corresponding to obtaining a channel state information (CSI) report configuration from a base station, wherein the CSI report configuration includes one or more measurement resource sets). From the power consumption perspective, it would be helpful to let UE turn off some antenna panels. However , in Rel-15 NR, the standard does not well support any scheme to enable UE to efficiently turn on-off or activate/deactivate any antenna ports. It lacks coordination between UE and gNB for antenna ports activation/deactivation. Therefore, to improve UE power efficiency, gNB can inform UE to activate or de-activate some non-useful panels through L1 or L2 signaling. Meanwhile, UE may need to report some
information so that gNB can make a proper decision considering performance, power consumption and latency. The mechanism of activating/de-activating some UE antenna ports for CSI/beam measurement is helpful for UE power saving (corresponding to sending a CSI report to the base station in response to a CSI measurement in the one or more measurement resource sets; supporting deactivation of antenna ports ( See sections 1-3) , wherein the one or more measurement resource sets each comprise a first resource subset and a plurality of second resource subsets, the second resource subsets each supporting the deactivation of base station antenna ports, the method further comprising: obtaining a message from the base station indicating at least one of the first resource subsets and the second resource subsets for the CSI measurement, wherein the message comprises a medium access control (MAC) control element (MAC-CE) or downlink control information (DCI) ( See sections 1-3), and
wherein the one or more measurement resource sets each comprise a first resource subset and a plurality of second resource subsets, the second resource subsets each supporting the deactivation of base station antenna ports, and the CSI report includes a resource identifier and a resource subset identifier associated with the CSI measurement in response to the CSI report configuration including the second resource subsets( See sections 1-3).
For independent and dependent claims 1,3,4,21,and 23, ZTE ( ON UE Adaptation to Maximum Number of MMO Layers) discloses all the subject matter of the claimed invention with the exception of one or more measurement resource sets supporting deactivation of base station antenna ports in a communications network. Khoshnevisan et al. (2023/0344578) from the same or similar fields of endeavor teaches a provision of one or more measurement resource sets supporting deactivation of base station antenna ports in a communications network ( See paragraphs 046 lines 1-15, 0049 lines 1-5, and details of claim 39). Thus, it would have been obvious to the person of ordinary skill in the art before the effective filing date of the claimed invention to use one or more measurement resource sets supporting deactivation of base station antenna ports in a communications network as taught by Khoshnevisan et al. (2023/0344578) in the communications of ZTE for the purpose of setting to support the activation/deactivation of the ports to save power.
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.
Claims 14,16, 17, 26, and 28 are rejected under 35 U.S.C. 103 as being unpatentable over ZTE ( ON UE Adaptation to Maximum Number of MMO Layers) in view of Khoshnevisan et al. ( 2023/0344578) and further in view of Nam (2016?0157218).
For claims 14,16, 17, 26, and 28 , ZTE ( ON UE Adaptation to Maximum Number of MMO Layers) discloses a method of wireless communication at a user equipment (UE) (sections 1-3): In this contribution, the aspects of CSI reporting when UE adapts to maximum number of MIMO layer are discussed.

For independent and dependent claims 14,16, 17, 26, and 28 , ZTE ( ON UE Adaptation to Maximum Number of MMO Layers) discloses all the subject matter of the claimed invention with the exception of one or more measurement resource sets supporting deactivation of base station antenna ports in a communications network. Khoshnevisan et al. (2023/0344578) from the same or similar fields of endeavor teaches a provision of one or more measurement resource sets supporting deactivation of base station antenna ports in a communications network ( See paragraphs 046 lines 1-15, 0049 lines 1-5, and details of claim 39). Thus, it would have been obvious to the person of ordinary skill in the art before the effective filing date of the claimed invention to use one or more measurement resource sets supporting deactivation of base station antenna ports in a communications network as taught by Khoshnevisan et al. (2023/0344578) in the communications of ZTE for the purpose of setting to support the activation/deactivation of the ports to save power.
For Claims 14,16, 17, 26,and 28, ZTE ( ON UE Adaptation to Maximum Number of MMO Layers) in view of Khoshnevisan et al. ( 2023/0344578) disclose all the subject matter of the claimed invention with the exception of memory and processor in a communications network. Nam et al. from the same or similar fields of endeavor teaches a provision of the memory and processor ( See paragraphs 0014 and 0052). Thus, it would have been obvious to the person of ordinary skill in the art at the time of the invention to use memory and processor as taught by Nam et al. in the communication network of , ZTE ( ON UE Adaptation to Maximum Number of MMO Layers) in view of Khoshnevisan et al. ( 2023/0344578) for the purpose of storing codes in the memory to execute the process by the processor.
Claims 2,5-13,15,18,19,20,22,24,25,27,29,and 30 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Zhou et al. (2023/0344592) and Abdelghaffar et al. (2023/015660) are all cited to show system which are considered pertinent to the claimed invention.
