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 § 103
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 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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 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.
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.
Claims 1-4, 11-14, 21-24 and 26-29 are rejected under 35 U.S.C. 103 as being unpatentable over KIM; Kyungjoong et al. US PGPUB 20230198702 A1, in view of LI; Yingyang et al. US PGPUB 20150098409 A1.

One situation is that the E-PDCCH and the PDSCH are multiplexed in one PRB pair, where because the reference signal of the E-PDCCH and the PDSCH are sent on a same PRB pair, the reference signal of the E-PDCCH may possibly be used to demodulate the PDSCH.)

The PDSCH may be transmitted after the control channel transmission interval, and scheduling information such as the detailed mapping location in the frequency domain and the modulation scheme is indicated by the DCI transmitted through the PDCCH.)

However, Molavian teaches
wherein to receive the DL signaling that indicates the MCS update, ([0354] In step 1310, a UE (such as the UE 116) is configured a number of sets of co-scheduled cells. In step 1320, the UE receives an indication for co-scheduling a first cell and a second cell from the number of configured sets of co-scheduled cells. [0366] In a sixth example, a modulation and coding scheme (MCS) parameter can be cell-common for a set of co-scheduled cells or can be provided by differential indication. In one example, the DCI format can provide a single MCS value that is applied to the set of co-scheduled cells,)
receive, at a time length prior to the data from the PDSCH transmission that is multiplexed with the PDCCH transmission, ([0307] In one example, the UE can be configured a parameter a that controls a maximum number of coded modulation symbols for M-DCIs in a PDSCH, in order to control a maximum number of time/frequency resources allocated to M-DCIs that are multiplexed on the PDSCH.) the DL signaling that indicates the MCS update via downlink control information (DCI). (Fig. 13, 1360 [0354] In step 1360, the UE receives the first and second PDSCHs or transmits the first and second PUSCHs respectively on the first and second co-scheduled cells based on the first value and the second value.)
in order to reduce control overhead by controlling a maximum number of resources allocated to DCI multiplexed on the PDSCH.
Kim and Molavian are analogous art in the same field of endeavor of wireless communication. It would have been obvious before the effective filing date of the claimed invention to a person with ordinary skill in the art to modify the method in Kim with the technique of M-DCI in order to reduce control overhead by controlling a maximum number of resources allocated to DCI multiplexed on the PDSCH.

However, Molavian teaches
wherein the at least one processor, individually or in any combination, is further configured to:
provide, for the network node and prior to the data from the PDSCH transmission multiplexed with the PDCCH transmission, an acknowledgement (ACK) indication for the DCI; ([0386] For example, when a DCI format for multi-cell scheduling of PDSCHs includes zero bits for PUCCH resource indication, the UE can determine a PUCCH resource for transmission of HARQ-ACK feedback corresponding to the co-scheduled PDSCHs in a PUCCH resource provided by higher layers) and
apply the MCS update for the PDSCH transmission multiplexed with the PDCCH transmission based on a time delay triggered by providing the ACK indication. ([0255] To account for a MAC CE processing delay, the UE can apply the multi-cell scheduling MAC CE in a first slot that is after slot k+3N.sub.slot.sup.subframe,μ where k is a slot where the UE would transmit a PUCCH with HARQ-ACK information for the PDSCH providing the MAC CE and μ is the SCS configuration for the PUCCH.)

Kim and Li does not teach receive, from the network node, a default PDSCH transmission that is multiplexed with a default PDCCH transmission based on the default MCS configuration and the default monitoring occasion periodicity.
However, Molavian teaches
receive, from the network node, a default PDSCH transmission that is multiplexed with a default PDCCH transmission based on the default MCS configuration and the default monitoring occasion periodicity. ([0408] In yet another example, a UE (such as the UE 116) determines information of operation level(s) corresponding to DCI fields with multi-cell mapping for scheduling a PDSCH/PUSCH on a cell from a set of co-scheduled cells based on predetermined or configured UE measurements.)

However, Molavian teaches wherein to provide the DL signaling that indicates the MCS update, ([0354] In step 1310, a UE (such as the UE 116) is configured a number of sets of co-scheduled cells. In step 1320, the UE receives an indication for co-scheduling a first cell and a second cell from the number of configured sets of co-scheduled cells.

But they do not teach wherein the at least one processor, individually or in any combination, is further configured to: receive, from the UE and prior to the modulated data associated with the PDSCH transmission multiplexed with the PDCCH transmission, an acknowledgement (ACK) indication for the DCI; the at least one processor, individually or in any combination, is configured to: provide the modulated data associated with the PDSCH transmission, after the beginning of the future time period, based on the MCS update and also based on a time delay triggered by reception of the ACK indication.
However, Molavian teaches
