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 .
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Claims 1-16 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1-16 of U.S. Patent No. US 12,308,918 B2 in view of Rahman et al (US 20210044340 A1).
Regarding claims 1, 9-13 and 16 (instant application), claims 1 and 11-16 (US 12,308,918 B2) substantially disclose the corresponding claim limitations, respectively (See mapping below).
However Claims 1 and 11-16 of the U.S Patent ( 12,308,918 B2) do not explicitly teach determining wherein the rank set comprises a first rank set and a second rank set, and the CSI report configuration information comprises at least one parameter DQ for indicating basis vectors for the first basis set for the first rank set and at least one parameter D1 for indicating D1 basis vectors for the first basis set for the second rank set (see mapping below).
Rahman et al teaches determining a precoding matrix based on the first indication information (see para [0196-0197] for…… he UE is configured with less than 32 channel state information reference signal (CSI-RS) antenna ports, or the UE is allowed to report the rank value ν>2, or the UE is configured with R=2 indicating that the UE is allowed to report up to 2 precoding matrices in each subband configured for the CSI feedback.
In one embodiment, the CSI feedback includes a set of M.sub.ν FD basis vectors, where M.sub.ν is determined based on the parameter p if the rank value ν belongs to the first rank set and based on the parameter ν.sub.0 if the rank value ν belongs to the second rank set.)
It would have been obvious to one of ordinary skill in the art, at the time of filing or before the effective filing date of the claimed invention, to modify the claims of the above US Patent to include a precoding matrix indicator (PMI) indicating a coefficient matrix C.sub.l, a spatial basis matrix A.sub.l, and a frequency domain basis matrix B.sub.l for each layer. Furthermore the precoding matrix would be generated from codebook with non-constant modulus precoding matrix having column vector of which amplitude values of elements are symmetrical or partially symmetrical. Such modification would facilitate a wireless network node to accurately adjust beam shape and subsequently enhance the performance of the wireless network node.
