Claim Rejections - 35 USC § 102
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.
Claims 1, 2, 12-14, 16, and 17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Rahman, et al., U.S. Pub. No. 2019/0280750 (hereinafter referred to as Rahman).
With regard to claim 1, Rahman discloses receiving configuration information of a second communication node (Rahman, [0005]-[0007]; Claim 1); and reporting channel state information to the second communication node according to the configuration information (Rahman, [0005]-[0007]; Claim 1); wherein the channel state information comprises a precoding matrix indicator, and the precoding matrix indicator comprises a strongest coefficient indicator (Rahman, [0179]-[0185]); and wherein a precoding matrix corresponding to the precoding matrix indicator is formed by combining first coefficients with a first group of vectors, or a precoding matrix corresponding to the precoding matrix indicator is formed by combining first coefficients with a first group of vectors and a second group of vectors, and the strongest coefficient indicator is used to indicate an index of a strongest coefficient in the first coefficients (Rahman, [0211]-[0218]).
With regard to claim 2, Rahman further discloses wherein the index of the strongest coefficient comprises an index of a first dimension and an index of a second dimension (Rahman, [0110]-[0114]); and wherein the index of the first dimension corresponds to the first group of vectors, and the index of the second dimension corresponds to the second group of vectors (Rahman, [0110]-[0114]).
With regard to claim 12, Rahman further discloses wherein the channel state information further comprises a first number indicator, wherein the first number indicator is used to indicate the number K of coefficients that need to be reported in the first coefficients, and the first number indicator is reported by using a field formed by A bits, and K denotes a value of the first number indicator plus 1, wherein the value of the first number indicator is a value of the field formed by the A bits, and A is a non-negative integer (Rahman, [0167]-[0170]).
With regard to claim 13, Rahman further discloses wherein the channel state information further comprises a first number indicator, wherein the first number indicator is used to indicate a number K of coefficients whose values are not 0 in the first coefficients, and the first number indicator is reported by a field formed by A bits, and K denotes a value of the first number indicator plus 1, wherein the value of the first number indicator is a value of the field formed by the A bits, and A is a non-negative integer (Rahman, [0167]-[0170]).
With regard to claim 14, Rahman discloses determining configuration information (Rahman, [0005]-[0007]; Claim 1); and sending the configuration information to a first communication node to enable the first communication node to report channel state information according to the configuration information (Rahman, [0005]-[0007]; Claim 1), wherein the channel state information comprises a precoding matrix indicator, and the precoding matrix indicator comprises a strongest coefficient indicator (Rahman, [0179]-[0185]); and wherein a precoding matrix corresponding to the precoding matrix indicator is formed by combining first coefficients with a first group of vectors, or a precoding matrix corresponding to the precoding matrix indicator is formed by combining first coefficients with a first group of vectors and a second group of vectors, and the strongest coefficient indicator is used to indicate index of a strongest coefficient in the first coefficients (Rahman, [0211]-[0218]).
With regard to claim 16, Rahman discloses a non-transitory storage medium storing a computer program which, when executed by a processor, causes the processor to perform (Rahman, [0010]) an information transmission method, wherein the method comprises: receiving configuration information of a second communication node (Rahman, [0005]-[0007]; Claim 1); and reporting channel state information to the second communication node according to the configuration information (Rahman, [0005]-[0007]; Claim 1); wherein the channel state information comprises a precoding matrix indicator, and the precoding matrix indicator comprises a strongest coefficient indicator (Rahman, [0179]-[0185]); and wherein a precoding matrix corresponding to the precoding matrix indicator is formed by combining first coefficients with a first group of vectors, or a precoding matrix corresponding to the precoding matrix indicator is formed by combining first coefficients with a first group of vectors and a second group of vectors, and the strongest coefficient indicator is used to indicate an index of a strongest coefficient in the first coefficients (Rahman, [0211]-[0218]).
With regard to claim 17, Rahman further discloses wherein the index of the strongest coefficient comprises an index of a first dimension and an index of a second dimension (Rahman, [0110]-[0114]); and wherein the index of the first dimension corresponds to the first group of vectors, and the index of the second dimension corresponds to the second group of vectors (Rahman, [0110]-[0114]).
Allowable Subject Matter
Claims 3-11 and 18-21 are objected to as being dependent upon a rejected base claims, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
