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.
Claim(s) 1, 6-7, 13, 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over Khoshnevisan et al. (US 2020/0336239 A1) in view of SEO et al. (US 2016/0020875 A1), further in view of He et al. (US 2020/0404634 A1).
Regarding claims 1, 13 and 20, Khoshnevisan et al. discloses:
A method, comprising:
receiving, by a User Equipment (UE), a Downlink Control Information (DCI) scheduling:
a first Physical Downlink Shared Channel (PDSCH) in a first component carrier (CC), and
a second PDSCH in a second CC; ([0005]: “The method may include receiving a first downlink control information (DCI) message for a first downlink data transmission and a second DCI message for a second downlink data transmission.”), ([0061]: “a base station 105 may transmit multiple downlink control message (e.g., DCI messages) to a UE 115 (e.g., via a PDCCH) to schedule multiple corresponding downlink data messages (e.g., transmitted via a PDSCH).”);
calculating, by the UE, a comparison value for the DCI ([0022]:”if the UE determines that the DAI fields in the detected downlink control messages include different numbers of bits (e.g., do not include a same number of bits), the UE may order detected cDAIs across CCs and then across PDCCH monitoring occasions. The UE may compare consecutive cDAIs to detect any missing values, for example, by comparing cDAIs with the same bit size, without changing the bit size and by comparing cDAIs with different bit sizes using the smaller bit size”); and
transmitting one or more Acknowledgement/Negative Acknowledgement (A/N) bits based on the comparison value, ([0022]: “If the UE detects any missed downlink control messages, the UE may report a NACK to the base station in a feedback message corresponding to the missed downlink control message.”).

Although Khoshnevisan et al. fails to teach a Downlink Control Information (DCI) scheduling both: a first Physical Downlink Shared Channel (PDSCH) in a first component carrier (CC), and a second PDSCH in a second CC, this claimed feature is well known in the art and is disclosed in SEO et al.
SEO et al. teaches ([0097]: “Referring to FIG. 12, only one DCI is transmitted, and a separate PDSCH is defined for each carrier, such that one DCI can schedule two PDSCHs located in different carriers. That is, the same DCI content, for example, MCS (modulation and coding scheme), resource allocation information, RV (redundancy version), etc. may be applied to each of two carriers. Needless to say, data corresponding to PDSCH contents may be different from each other.”). See figures 9 and 12.

Therefore, it would have been obvious to those having ordinary skills in the art before the effective filing date of the claimed invention to implement one DCI can schedule two PDSCHs located in different carriers.
Khoshnevisan et al further fails to teach comprising
The calculating comprising performing a count over a plurality of received PDSCHs, each of the plurality of received PDSCHs having been received in a CC with a carrier index that is less than or equal to a carrier index of a reference CC.
HE et al. in the same field of invention, teaches this feature.
([0087]: “the UE 102 may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH). The PDSCH may be scheduled in a slot of a plurality of slots. The PDSCH may be further scheduled on a component carrier (CC) of a plurality of CCs. The PDCCH may include a downlink control information (DCI) that includes: a total downlink assignment index (DAI) for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH, wherein the total DAI indicates a total number of pairs of CCs and slots for the HARQ-ACK feedback; and a counter DAI based on an accumulative number of other PDCCHs. The UE 102 may attempt to decode the PDSCH received within the scheduled slot on the scheduled CC. The UE 102 may encoded the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI. A position of the bit within the HARQ-ACK feedback may be based on the counter DAI.”). See also abstract. In other words, the total DAI is indeed read as the reference index, while the number of HARQ is referred to as the carrier index. The total DAI indicates the total number of transmissions at the end of each time interval, and the HARQ index is used to identify the location of any missed transmission within that total.
Therefore, it would have been obvious to those having ordinary skills in the art before the effective filing date of the claimed invention to describe the relationship between the DAI and HARQ in the process of downlink data transmission.
Regarding claims 6 and 18, He et al. teaches wherein the performing of the count comprises counting PDSCHs. ([0250]: “The PDCCH may include a downlink control information (DCI) that includes: a total downlink assignment index (DAI) for hybrid automatic repeat request acknowledgement (HARQ-ACK0 feedback of the PDSCH)”). The total DAI indicates the total number of transmission (PDSCH).
Regarding claims 7 and 19, Khoshnevisan et al. teaches wherein the performing of the count comprises counting PDCCHs. ([0083]:”UE 115-a may use the largest tDAI value to detect missed downlink control message 205-b. For example, “10” may indicate that three DCI messages were transmitted in the monitoring occasion (e.g., depending on a counter value), while “110” may indicate that seven DCI messages were transmitted in the monitoring occasion (e.g., depending on the counter value).”).
Allowable Subject Matter
Claims 2-5, 8-12,14-17 are objected to as being dependent upon a rejected base
claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The prior art made of record: Choi et al. (US 11,653,353 B2), in the same field of invention, discloses method for downlink data reception and HARQ-ACK transmission in wireless communication system. See fig.23.

Choi et al. teaches performing a count over received PDSCHs of CCs with carrier indexes up to and including a carrier index of a reference CC.
Choi et al. teaches (“receives a first physical downlink control channel (PDCCH) for scheduling of a first physical downlink shared channel (PDSCH), the first PDCCH including a first counter downlink assignment indicator (DAI) indicating the number of PDSCHs scheduled up to a serving cell at a time point at which the first PDCCH is monitored and a first total DAI indicating the number of all PDSCHs scheduled in the serving cell until a time point at which a PDCCH is monitored, receives a second PDCCH for scheduling of a second PDSCH, the second PDCCH including a second counter DAI and a second total DAI, receives the first PDSCH based on the first PDCCH, receives the second PDSCH based on the second PDCCH, and transmits, to the base station, uplink control information (UCI) including hybrid automatic repeat request (HARQ)-acknowledge (ACK) codebook for the first PDSCH and the second PDSCH, a value of the second counter DAI being determined based on the number of bits of the first counter DAI is different from the number of bits of the second counter DAI.”), Col. 3, lines 50-67 and col. 4, lines 1-25).
