Patentability shall not be negatived by the manner in which the invention was made. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under pre-AIA 35 U.S.C. 103(a) 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. Claims 6-7 and 15 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over GOTOH et al. US 2021/0045092 Al in view of KIM et al.US 2023/0067370 A1 Regarding claims 6 and 15, GOTOH et al. US 2021/0045092 Al discloses all features with respect to claims 2 and 11, respectively GOTOH does not disclose wherein a time-frequency resource of the second channel is M control channel elements (CCEs), and wherein M is greater than or equal to 1. KIM et al.US 2023/0067370 Al discloses wherein a time-frequency resource of the second channel is M control channel elements (CCEs), and wherein M is greater than or equal to 1. [0089] Such DCI format is independently applicable per UE and PDCCHs of several UEs may be multiplexed within one subframe. The PDCCH is composed of an aggregate of one or several control channel elements (CCEs). The CCE is a logical allocation unit used to provide a PDCCH with a coding rate according to radio channel state. The CCE refers to a unit corresponding to 9 sets of REGs composed of four resource elements. The BS may use {1, 2, 4, 8} CCEs in order to configure one PDCCH signal and {1, 2, 4, 8} is referred to as a CCE aggregation level. [0090] The number of CCEs used to transmit a specific PDCCH is determined by the BS according to channel state. The PDCCH configured according to UE is interleaved and mapped to a control channel region of each subframe by a CCE-to-RE mapping rule. The location of the PDCCH may depend on the number of OFDM symbols for a control channel of each subframe. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify GOTOH by including wherein a time-frequency resource of the second channel is M control channel elements (CCEs), and wherein M is greater than or equal to 1, as taught by KIM in order to configure one PDCCH signal (see KIM i[0089]). Regarding claims 7, the combination of GOTOH and KIM discloses all features with respect to claim 6. GOTOH does not disclose wherein the M CCEs are consecutive CCEs. KIM et al.US 2023/0067370 Al discloses wherein the M CCEs are consecutive CCEs. [0089] Such DCI format is independently applicable per UE and PDCCHs of several UEs may be multiplexed within one subframe. The PDCCH is composed of an aggregate of one or several control channel elements (CCEs). The CCE is a logical allocation unit used to provide a PDCCH with a coding rate according to radio channel state. The CCE refers to a unit corresponding to 9 sets of REGs composed of four resource elements. The BS may use {1, 2, 4, 8} CCEs in order to configure one PDCCH signal and {1, 2, 4, 8} is referred to as a CCE aggregation level. [0090] The number of CCEs used to transmit a specific PDCCH is determined by the BS according to channel state. The PDCCH configured according to UE is interleaved and mapped to a control channel region of each subframe by a CCE-to-RE mapping rule. The location of the PDCCH may depend on the number of OFDM symbols for a control channel of each subframe. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify GOTOH by including wherein wherein the M CCEs are consecutive CCEs, as taught by KIM in order to configure one PDCCH signal (see KIM [0089]).
