Drawings 06-37 AIA The drawings were received on April 26, 2024 . These drawings are acceptable . Claim Objections 07-29-01 AIA Claim 10 is objected to because of the following informalities: Line 1 of claim 1 recites “A network node for wireless communication, comprising, comprising:” It should be corrected as - - A network node for wireless communication, comprising: - - Appropriate correction is required. Claim Rejections - 35 USC § 103 07-20-aia AIA 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. 07-21-aia AIA Claim (s) 1-2, 10-11, 19-20, and 25-26 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ren et al. (hereinafter “Ren”, US 2023/0299821) in view of Rahman et al. (hereinafter “Rahman”, US 2016/0142117) . Regarding claims 1, and 19 , Ren discloses a user equipment (UE) for wireless communication (i.e., terminal 1200 as shown in Fig. 12) , and a method for wireless communication by a UE, comprising: a processing system that includes one or more processors (i.e., processor 1210) and one or more memories (i.e., memory 1209) coupled with the one or more processors (i.e., memory 1209 coupled to processor 1210) , the processing system configured to cause the UE to: select, a first spatial domain (SD) basis for a first layer (i.e., a valid orthogonal basis as described in paragraph 0043) ; select, beams that are orthogonal to the first SD basis, one or more additional SD bases for one or more additional layers (i.e., the valid orthogonal basis includes a spatial domain orthogonal basis as described in paragraph 0043) ; and transmit, to a network node, information that indicates the first SD basis selected for the first layer, the one or more additional SD bases selected for the one or more additional layers, and a co-phase coefficient associated with the first SD basis and the one or more additional SD bases (i.e., sending information for determining a position of a valid orthogonal basis including a spatial domain orthogonal basis, and a coefficient of the valid orthogonal basis to a network side as described in paragraphs 0042-0043) . Ren, however, does not expressly disclose select, from a set and/or a subset of candidate beams in a codebook. In a similar endeavor, Rahman discloses methods to calculate linear combination pre-coders for MIMO wireless communication systems. Rahman also discloses select, from a set and/or a subset of candidate beams in a codebook (i.e., basis beam vectors selected from a master beam set or retrieved from memory, a codebook enables selection of a linear combination of at least a subset of the beams as described in Abstract) . Therefore, it would have been obvious to one of ordinary skilled in the art to modify the teachings of the cited references, and arrive at the present invention. The motivation/suggestion for doing so would have been to enable the UE to feedback with the best beam selection and reduce overhead. Regarding claims 10, and 25 , Ren discloses network node for wireless communication (i.e., network-side device 1300 as shown in Fig. 13) , and a method for wireless communication by a network node, comprising: a processing system that includes one or more processors (i.e., processor 1304) and one or more memories (i.e., memory 1305) coupled with the one or more processors (i.e., memory 1305 coupled to processor 1304) , the processing system configured to cause the network node to: transmit, to a user equipment (UE), one or more reference signals (i.e., the network side uses signaling to trigger the terminal to send a sounding reference signal (SRS) as described in paragraph 0108) ; and receive, from the UE, information that indicates a first spatial domain (SD) basis selected for a first layer, one or more additional SD bases selected for one or more additional layers from a subset of the candidate beams in the codebook that are orthogonal to the first SD basis, and a co-phase coefficient associated with the first SD basis and the one or more additional SD bases (i.e., sending information for determining a position of a valid orthogonal basis including a spatial domain orthogonal basis, and a coefficient of the valid orthogonal basis to a network side as described in paragraphs 0042-0043) . Ren, however, does not expressly disclose information selected for a first layer, from a set and/or a subset of candidate beams in a codebook. In a similar endeavor, Rahman discloses methods to calculate linear combination pre-coders for MIMO wireless communication systems. Rahman also discloses information selected for a first layer, from a set and/or a subset of candidate beams in a codebook (i.e., basis beam vectors selected from a master beam set or retrieved from memory, a codebook enables selection of a linear combination of at least a subset of the beams as described in Abstract) . Therefore, it would have been obvious to one of ordinary skilled in the art to modify the teachings of the cited references, and arrive at the present invention. The motivation/suggestion for doing so would have been to enable the UE to feedback with the best beam selection and reduce overhead. Regarding claims 2, 11, 20, and 26 , Ren and Rahman disclose all limitations recited within claims as described above. Rahman also discloses wherein the co-phase coefficient has an identical value for the first SD basis and the one or more additional SD bases (i.e., selected beams are partitioned into groups such that beams in the same group share common SB co-phase and coefficient as described in paragraph 0288) . 07-21-aia AIA Claim (s) 3-4, 6, 12-13, 15, 21-22, 24, 27-28, and 30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ren in view of Rahman and further in view of Jeon et al.
