Claim Rejections - 35 USC § 103
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 1-5, 7-9 and 11-14 are rejected under 35 U.S.C. 103 as being unpatentable over FRENNE et al (USPGPUB 2014/0071934) in view of SAYANA et. al. (USPGPUB 20130308572; cited by Applicant on November 11, 2022.)
Regarding claim 1 and 19, Frenne disclose method for configuring a physical downlink control channel (PDCCH) (see abstract, para: 0013, 0015-0018, 0020, 0034, decoding/configuration of PDCCH), comprising:
determining a subset of aggregation levels from a first set of aggregation levels (see abstract, para: 0138-0140, subset from set of aggregation levels); and
transmitting configuration information of the subset of aggregation levels to a user equipment (UE) (see para: 0053, communicate subset data associated with aggregation levels.)
In addition, Frenne further disclose a memory, a processor; and a computer program stored on the memory and capable of running on the processor (see figs. 0029, 0030; para: 0149-0151.)
Although Frenne is not clear on teaching wherein the first set of aggregation levels is a complete set of aggregation levels configured for a first-type UE, a second set of aggregation levels is a complete set aggregation levels configured for a second-type UE; and aggregation levels in the first set of aggregation levels are not the same or not completely the same as aggregation levels in the second set of aggregation levels, in analogous art, SAYANA disclose wherein the first set of aggregation levels is a complete set of aggregation levels configured for a first-type UE, (see para: 0185, 0186, non-MTC type mapped to {1, 2, 4, 8}, and a second set of aggregation levels (see para: 0185, 0186, MTC type mapped to higher aggregation levels mapped to {eg. 1, 2, 4, 8…16} is a complete set aggregation levels configured for a second-type UE (see Fig. 4A, para: 0105-0186); and aggregation levels in the first set of
aggregation levels are not the same or not completely the same as aggregation levels in the second set of aggregation levels (see para: 0185, 0186.)

Therefore, it would have been obvious to one of ordinary skilled in the art at the
time of the invention to implement wherein the second set of aggregation levels is a subset of the first set of aggregation levels as taught by SAYANA with the teachings of Frenne for the purpose of enhancing service coverage that the PDCCH can reach with respect to UE specific type devices.
Regarding claim 4, Frenne further disclose wherein a maximum aggregation level in the first set of aggregation levels is greater than a maximum aggregation level in the second set of aggregation levels (see para: 0029-0032, 0131.)
Regarding claim 5, Frenne further disclose wherein the first set of aggregation levels comprises at least one aggregation level that is different from any aggregation level in the second set of aggregation levels, and the different aggregation level is less than a maximum aggregation level in the second set of aggregation levels (see para; 0029-0033, 0131)

Regarding claim 9, Frenne further disclose wherein the first set of aggregation levels comprises at least one aggregation level that is different from any aggregation level in the second set of aggregation levels (see para: 0140, first set AL different from second set AL);
wherein, the different aggregation level is configured for the user-specific search space of the first-type UE, and/or the different aggregation level is configured for a designated common search space used by the first-type UE (see para: 0015, 0019-0022, first-type UE utilize common search space.)
Regarding claim 11, Frenne further disclose wherein a capability of the first-type UE is different from a capability of the second-type UE;
and/or, the first-type UE and the second-type UE have different network requirements (see para: 0015-0018, 0029, 0079-0083.)
Regarding claim 12, although Frenne fail to teach wherein a maximum aggregation level in the first set of aggregation levels is a power of 2, where n is a positive integer greater than or equal to 5, in analogous art, SAYANA disclose wherein a maximum aggregation level in the first set of aggregation levels is a power of 2, where n is a positive integer greater than or equal to 5 (see abstract, table 8, fig. 5, para: 0016-0018.)
Therefore, it would have been obvious to one of ordinary skilled in the art at the
time of the invention to implement wherein a maximum aggregation level in the first set of aggregation levels is a power of 2, where n is a positive integer greater than or equal to 5 with the teachings of Frenne for the purpose of enhancing service coverage that the PDCCH can reach with respect to UE specific type devices.

Claim(s) 6, 15, 16 and 19-21 are rejected under 35 U.S.C. 103 as being unpatentable over FRENNE et al (USPGPUB 2014/0071934) in view of SAYANA et. al. (USPGPUB 20130308572) as applied to claims 1 and 19 above, and further in view of DOU (USPGPUB 20200076554.)
Regarding claim 6, Frenne and SAYANA fail to teach wherein the first set of aggregation levels comprises a first target aggregation level, and the first target aggregation level is determined based on a number of resources in a control resource set of the UE, in analogous art, DOU disclose wherein the first set of aggregation levels comprises a first target aggregation level (see fig. 2 & 4, Para: 0123, 0127, 0194, first DCI is target DCI and target DCI is a target aggregation level), and the first target aggregation level is determined based on a number of resources in a control resource set of the UE (see para: 0140-0142, 0145, target AL based on number of resources in a control resource set of a UE/terminal.)
Therefore, it would have been obvious to one of ordinary skilled in the art at the
time of the invention to implement wherein the first set of aggregation levels comprises a first target aggregation level, and the first target aggregation level is determined based on a number of resources in a control resource set of the UE as taught by DOU with the combined teachings of Frenne and SAYANA for the purpose of enhancing service coverage that the PDCCH can reach with respect to UE devices.
Regarding claim 15, Frenne and SAYANA fail to disclose wherein the subset of aggregation levels comprises a first target aggregation level, and the first target aggregation level is determined by:
obtaining configuration information of a control resource set;

Therefore, it would have been obvious to one of ordinary skilled in the art at the
time of the invention to implement wherein the subset of aggregation levels comprises a first target aggregation level, and the first target aggregation level is determined by:
obtaining configuration information of a control resource set;
determining a first aggregation level supported by the UE based on the configuration information of the control resource set;
