Office Action

§103
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 1-5,12-16,24-26, and 31-34 are rejected under 35 U.S.C. 103 as being unpatentable over Ericsson Telefon ( WO 2020/225642) in view of CATT (Discussion on CSI enhancements for Rel-17). For claims 1-5,12-16,24-26, and 31-34, Ericsson Telefon ( WO 2020/225642 discloses a method in a network node configured to communicate with a wireless device, WD, the method comprising: (cf. [0032]) relates to overhead reduction in channel state information, CSI, reporting between a wireless device and a network node operating according to the 3GPP New Radio standard. It is noted that this scope is identical to the scope of the present application, receiving from the WD an indication of a channel state information, CSI, reporting capability for a codebook based CSI comprising information of at least one frequency domain, FD, basis vector; (cf. [0032-0033]) discloses CSI reporting based on codebooks with frequency domain basis vectors according to 3GPP Release 16. The fact that a wireless device signals its capability to operate with codebook types of a specific 3GPP Release is implicit since this is the case in any 3GPP Release; and configuring the WD to report the codebook based CSI in multiple CSI reporting groups with different priorities, the FD basis vector information being associated with CSI in a CSI reporting Group having a highest priority among the multiple CSI reporting groups; (cf. [0038], [0092-003]) discloses that the FD basis vector information is part of the CSI group with the highest priority. For independent claim 1, Ericsson Telefon ( WO 2020/225642) discloses all the subject matter of the claimed invention with the exception of the FD basis vector information being associated with CSI in a CSI reporting group of the multiple CSI reporting groups, a first CSI reporting group including first CSI grouped according to a priority criterion when a number of reported sub-band coefficients scales with bandwidth or according to a sub-band criterion when the number of reported sub-band coefficients does not scale with bandwidth in a communications network. CATT (Discussion on CSI enhancements for Rel-17) from the same or similar fields of endeavor teaches a provision of the FD basis vector information being associated with CSI in a CSI reporting group of the multiple CSI reporting groups, a first CSI reporting group including first CSI grouped according to a priority criterion when a number of reported sub-band coefficients scales with bandwidth or according to a sub-band criterion when the number of reported sub-band coefficients does not scale with bandwidth in a communications network . 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 the FD basis vector information being associated with CSI in a CSI reporting group of the multiple CSI reporting groups, a first CSI reporting group including first CSI grouped according to a priority criterion when a number of reported sub-band coefficients scales with bandwidth or according to a sub-band criterion when the number of reported sub-band coefficients does not scale with bandwidth in a communications network as taught by CATT (Discussion on CSI enhancements for Rel-17) in the communications network of Ericsson Telefon ( WO 2020/225642) for the purpose of reporting group including first CSI grouped according to a priority criterion when a number of reported sub-band coefficients scales with bandwidth or according to a sub-band criterion when the number of reported sub-band coefficients does not scale with bandwidth. For independent claims 12,23, and 31 are rejected for the same reason as in claim 1. For depending claims 2-5,13,14,15,16,2524,25,26,33,and 34, Ericsson Telefon ( WO 2020/225642) also discloses wherein a codebook of the codebook based CSI is a port selection codebook and the CSI further comprises indices of multiple selected CSI reference signal, CSI-RS, ports(cf. [0038], [0092-003]); wherein the port selection codebook is an enhanced type II port selection codebook defined in 3GPP New Radio Technical Release 17 and the WD is configured to report the FD basis vector information in CSI reporting Group 0(cf. [0038], [0092-003]); wherein the FD basis vector information includes an index indicating a set of selected FD basis vectors(cf. [0038], [0092-003]); and wherein the CSI further includes information of a plurality of layers and the FD basis vector information includes FD basis vector information for each layer of the plurality of layers. (cf. [0038], [0092-003]). Claims 6-11, 17-22,27-30, and 35-38 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. Zhang et al. (2024/0380442) and Petersson et al. (11,012,129) are all cited to show systems which are considered pertinent of the claimed invention.
