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 .
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.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim(s) 1, 7, and 8 is/are rejected under 35 U.S.C. 102(a)(1) and/or 102(a)(2) as being anticipated by Chen et al. (hereinafter referred to as “Chen”, US 2020/0274597).
As to claim 1, Chen teaches a channel information feedback method, comprising: performing channel estimation according to a first pilot signal sent by a first communication node, so as to acquire first channel information (paragraphs [0180]-[0181]); determining, according to the first channel information, a codebook set for quantized channel feedback (paragraph [0180]); selecting an optimal codeword from the codebook set, wherein the optimal codeword is used for quantitatively characterizing the first channel information (paragraph [0180]); and feeding back target indication information to the first communication node, wherein the target indication information is used for indicating the first communication node to determine the optimal codeword (paragraphs [0182] and [0193]-[0194]); wherein codewords in the codebook set conform to a model as follows: wherein W is a vector or matrix with Nt rows and r columns, Nt >= 2 and Nt is an integer, r>=1 and r is an integer, vi is a precoding vector or precoding matrix for array beam regulation, wherein W is a vector or matrix with Nt rows and r columns, Nt 2 and Nt is an integer, r>1 and r is an integer, vi is a precoding vector or precoding matrix for array beam regulation, α i is a complex number, and i ϵ {1,2,3,4} (paragraphs (0004], [0078], and [0193]-[0194]).
As to claim 7, Chen further teaches an electronic device, comprising: a processor; and a memory configured to store computer-executable instructions, wherein the executable instructions, when executed, enables the processor to perform the channel information feedback method according to claim 1 (paragraphs [0250]-[0252]).
As to claim 8, Chen further teaches a computer-readable medium, storing one or more programs, wherein the one or more programs, when executed by an electronic device comprising a plurality of application programs, enables the electronic device to perform the channel information feedback method according to claim 1 (paragraphs [0250]-[0252]).
Allowable Subject Matter
Claims 2-6 and 9-16 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.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
