Claim Rejections - 35 USC § 103
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Claim(s) 1, 5, 6, 7, 8, 13, 14, 15, 16, 18, 19, 20, 21, 22, 23, 24, and 25 is/are rejected under 35 U.S.C. 103 as being unpatentable over Qualcomm (Qualcomm Incorporated, “PDSCH and PUSCH enhancements for 52.6-71GHz band” cited in IDS received November 26, 2024) in view of WANG (US 20240023098 A1)
In regards to claim 1, Qualcomm (Qualcomm Incorporated, “PDSCH and PUSCH enhancements for 52.6-71GHz band” cited in IDS received November 26, 2024) teaches an information feedback method, performed by a terminal, comprising:
receiving at least one piece of downlink control information (DCI) (See [2.2.4 Multi-PDSCH/PUSCH with single grant] “The design of multi-PDSCH scheduling with single DCI can leverage Rel.16 multi-PUSCH grant as much as possible, such as the following…”);
dividing, into multiple physical downlink shared channel (PDSCH) subsets, a PDSCH set scheduled by each DCI, (See [2.2.4 Multi-PDSCH/PUSCH with single grant] “The design of multi-PDSCH scheduling with single DCI can leverage Rel.16 multi-PUSCH grant as much as possible, such as the following…”);
determining a downlink assignment index (DAI) corresponding to each of the PDSCH subsets (See [2.2.4 Multi-PDSCH/PUSCH with single grant] “…For multi-PDSCH grant, we need to define new way to indicate DAI, to avoid the misalignment of the dynamic feedback codebooks between the UE and gNB in the case of misdetection of one of the multi-PDSCH grants.…”); and feeding back a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the multiple PDSCH subsets according to the DAI corresponding to each of the PDSCH subsets (See [2.2.4 Multi-PDSCH/PUSCH with single grant] “…For multi-PDSCH grant, we need to define new way to indicate DAI, to avoid the misalignment of the dynamic feedback codebooks between the UE and gNB in the case of misdetection of one of the multi-PDSCH grants.…”);
The feedback feature of Qualcomm differs from that of claim 1 in the following manner: (1) Qualcomm is silent on wherein a PDSCH subset comprises more than one PDSCH , (2) Qualcomm is silent on wherein a counting granularity of the DAI is the PDSCH subset (3) Qualcomm is silent on where a quantity of PDSCHs in each PDSCH subset is determined based on information predefined by a protocol, (4) Qualcomm is silent on wherein the feeding back the HARQ-ACK for the multiple PDSCH subsets comprises performing HARQ-ACK feedback for the multiple PDSCH subsets at a single feedback position and (5) Qualcomm is further silent on wherein in a case that the HARQ-ACK feedback is performed for the multiple PDSCH subsets at the single feedback position, the DCI comprises a first DAI indication field, the first DAI indication filed is used to indicate a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets. Despite these differences similar features have been seen in other prior art involving feedback for a physical downlink shared channel (PDSCH).
WANG for example teaches a feature for feedback that involves dividing into multiple PDSCH subsets, PDSCH groups, a PDSCH set scheduled by DCI, wherein a PDSCH subset comprises more than one PDSCH. (“[0059] As shown in FIG. 4, the network device 120 may generate 410 DCI for scheduling multiple data channels. In some embodiments, the DCI may comprise slot information for the multiple data channels. In some embodiments, the DCI may comprise a new data indicator (NDI) field indicating a data transmission type. In some embodiments, the DCI may further comprise a redundancy version (RV) field. Of course, the DCI may further comprise any other suitable information. For example, the DCI may further comprise modulation and coding scheme (MCS) information. As another example, the DCI may further comprise HARQ process information. In another example, the DCI may further comprise a total number of the data channels scheduled by the DCI. [0060] According to embodiments of the present disclosure, the multiple data channels are divided into a plurality of groups, and one of bits in each of the NDI field and the RV field corresponds to one group among the plurality of groups. In other words, data channels within one group shares the same NDI and RV bits. In this way, the number of bits in DCI can be reduced significantly... [0068] FIG. 6 illustrates a schematic diagram 600 illustrating an example grouping of data channels scheduled by DCI according to embodiments of the present disclosure. In this example, C=8, and M=3. That is, there are 8 PDSCHs scheduled by one PDCCH, as shown by PDSCH #0 to #7 in FIG. 6, and there are 3 PDSCH groups in the DCI. With the above equations (1), (4) and (5), it is determined that PDSCH #0 and PDSCH #1 occupy Group #2 and PDSCH #3 occupy Group #1, and PDSCH #4, PDSCH #5, PDSCH #6 and PDSCH #7 occupy Group #2, as shown in FIG. 6…[0071] In these embodiments, the network device 120 may introduce one additional bit in the DCI to signal the number of data channels in each group (also referred to as a group size). DCI payload may be designed as below. [0072] DCI payload: [0073] multi-PDSCHs-grouping support—0 or 1 bit. [0074] 1 bit if the higher layer parameter multi-PDSCHs-Bundling-Flag is true. [0075] 0 bit otherwise. If multi-PDSCH-grouping support is 0, the network device 120 may set the group size=2, else if multi-PDSCH-grouping support is 1, the network device 120 may set the group size=4.”).
WANG further teaches with respect to the PDSCH subsets/groups, where a counting granularity of a DAI is the PDSCH group/subset (See [Fig. 8A] where C-DAI counts the PDSCH group/subset), where a quantity of PDSCHs in each PDSCH subset is determined based on information predefined by a protocol (See [Fig. 2] which illustrates a predefined relationship indicating a relationship between a quantity of PDSCHs in a PDSCH subset (i.e. PDSCH group size) and a Modulation and Coding Scheme), wherein the feeding back the HARQ-ACK for the multiple PDSCH subsets comprises performing HARQ-ACK feedback for the multiple PDSCH subsets at a single feedback position (See in [Fig. 8A] where the feedback for the PDSCH group indicated by C-DAI = 1, the PDSCH group indicated by C-DAI = 2, and the PDSCH group indicated by C-DAI = 3, is indicated by a single PUCCH or PUSCH) and wherein in a case that the HARQ-ACK feedback is performed for the multiple PDSCH subsets at the single feedback position, the DCI comprises a first DAI indication field, the first DAI indication field is used to indicate a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets (See [Fig. 8A] where a first DAI indication field, C-DAI = 1, 2, or 3, indicates a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets, Also read where it recites “[0099] FIG. 8A illustrates a schematic diagram 800A illustrating an example generation of HARQ feedback during scheduling of multiple data channels by DCI in a CC according to embodiments of the present disclosure. In this example, in the whole group of downlink data channels scheduled by a single DCI, counter DAIs for each downlink data channel in the whole group keep the same value as signaled in the DCI. The terminal device 110 may generate 1 or 2 HARQ bits for each downlink data channel depending on the supported TB numbers in this cell. A HARQ codebook may be generated in ascending order of the counter DAIs. [0100] As shown in FIG. 8A, PDCCH 810 schedules four PDSCHs, i.e., PDSCH #0 to #3, and the c-DAI in PDCCH 810 of slot #0 is 1. PDCCH 820 schedules two PDSCHs, i.e., PDSCH #4 and #5, and the c-DAI in PDCCH 820 of slot #4 is 2. PDCCH 830 schedules two PDSCHs, i.e., PDSCH #6 and #7, and the c-DAI in PDCCH 830 of slot #6 is 3. Assuming that the downlink data is received correctly on PDSCH #0 to #7. In case that 1 TB is supported, a HARQ codebook 840 may be generated. In case that 2 TBs are supported, a HARQ codebook 850 may be generated.”). WANG suggests performing these features in order to reduce the number bits required for encoding the downlink control information (DCI) (“[0060] According to embodiments of the present disclosure, the multiple data channels are divided into a plurality of groups, and one of bits in each of the NDI field and the RV field corresponds to one group among the plurality of groups. In other words, data channels within one group shares the same NDI and RV bits. In this way, the number of bits in DCI can be reduced significantly”)
Thus, based upon the teachings of WANG it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the feedback feature of Qualcomm by incorporating the PDSCH subset/group feature suggested by WANG, to arrive at claim 1. A person of ordinary skill in the art before the effective filing date of the claimed invention would have been motivated to make such a modification in order to reduce the number of bits required for encoding downlink control information (DCI).
In regards to claim 5, The combination of Qualcomm in view of WANG teaches the method according to claim 1, wherein the first PDSCH subset is any one of the following scheduled by the DCI: the 1st PDSCH subset, the last PDSCH subset, or a PDSCH subset of a preset index. Qualcomm in view of WANG is believed to arrive at method of claim 1, for the reasons provided with respect to claim 1 above. With respect to the remaining feature(s) of claim 5, Qualcomm is silent on wherein the first PDSCH subset is any one of the following scheduled by the DCI: the 1st PDSCH subset, the last PDSCH subset, or a PDSCH subset of a preset index. Despite these differences similar features have been seen in other prior art involving feedback for a physical downlink shared channel (PDSCH).
WANG for example teaches a feature for feedback that involves dividing into multiple PDSCH subsets, PDSCH groups, a PDSCH set scheduled by DCI, wherein a PDSCH subset comprises more than one PDSCH.

That is, there are 8 PDSCHs scheduled by one PDCCH, as shown by PDSCH #0 to #7 in FIG. 6, and there are 3 PDSCH groups in the DCI. With the above equations (1), (4) and (5), it is determined that PDSCH #0 and PDSCH #1 occupy Group #2 and PDSCH #3 occupy Group #1, and PDSCH #4, PDSCH #5, PDSCH #6 and PDSCH #7 occupy Group #2, as shown in FIG. 6…[0071] In these embodiments, the network device 120 may introduce one additional bit in the DCI to signal the number of data channels in each group (also referred to as a group size).

If multi-PDSCH-grouping support is 0, the network device 120 may set the group size=2, else if multi-PDSCH-grouping support is 1, the network device 120 may set the group size=4.”).
WANG further teaches with respect to the PDSCH subsets/groups, where a counting granularity of a DAI is the PDSCH group/subset (See [Fig. 8A] where C-DAI counts the PDSCH group/subset), wherein in a case that the HARQ-ACK feedback is performed for the multiple PDSCH subsets at the single feedback position, the DCI comprises a first DAI indication field, the first DAI indication field is used to indicate a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets, wherein the first PDSCH subset is any one of the following scheduled by the DCI: the 1st PDSCH subset (i.e. PDSCH subset with C-DAI = 1) , the last PDSCH subset (i.e. PDSCH subset with C-DAI = 3), or a PDSCH subset of a preset index (i.e. anyone of PDSCH subsets indicated by C-DAI = 1, 2, or 3),. (See [Fig. 8A] where a first DAI indication field, C-DAI = 1, 2, or 3, indicates a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets, Also read where it recites “[0099] FIG. 8A illustrates a schematic diagram 800A illustrating an example generation of HARQ feedback during scheduling of multiple data channels by DCI in a CC according to embodiments of the present disclosure.

PDCCH 820 schedules two PDSCHs, i.e., PDSCH #4 and #5, and the c-DAI in PDCCH 820 of slot #4 is 2. PDCCH 830 schedules two PDSCHs, i.e., PDSCH #6 and #7, and the c-DAI in PDCCH 830 of slot #6 is 3. Assuming that the downlink data is received correctly on PDSCH #0 to #7. In case that 1 TB is supported, a HARQ codebook 840 may be generated. In case that 2 TBs are supported, a HARQ codebook 850 may be generated.”). WANG suggests performing these features in order to reduce the number bits required for encoding the downlink control information (DCI) (“[0060] According to embodiments of the present disclosure, the multiple data channels are divided into a plurality of groups, and one of bits in each of the NDI field and the RV field corresponds to one group among the plurality of groups.

Thus, based upon the teachings of WANG it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the feedback feature of Qualcomm by incorporating the PDSCH subset/group feature suggested by WANG, to arrive at claim 5. A person of ordinary skill in the art before the effective filing date of the claimed invention would have been motivated to make such a modification in order to reduce the number of bits required for encoding downlink control information (DCI).
In regards to claim 6, The combination of Qualcomm in view of WANG teaches the method according to claim 1, wherein DAIs corresponding to other PDSCH subsets in the multiple PDSCH subsets except the first PDSCH subset are derived based on a predefined rule and the DAI corresponding to the first PDSCH subset. With respect to the method of claim 1, Qualcomm in view of WANG is believed to arrive at method of claim 1, for the reasons provided with respect to claim 1 above. With respect to the remaining feature(s) of claim 6, Qualcomm is silent on wherein DAIs corresponding to other PDSCH subsets in the multiple PDSCH subsets except the first PDSCH subset are derived based on a predefined rule and the DAI corresponding to the first PDSCH subset. Despite these differences similar features have been seen in other prior art involving feedback for a physical downlink shared channel (PDSCH).

WANG further teaches with respect to the PDSCH subsets/groups, where a counting granularity of a DAI is the PDSCH group/subset (See [Fig. 8A] where C-DAI counts the PDSCH group/subset), wherein in a case that the HARQ-ACK feedback is performed for the multiple PDSCH subsets at the single feedback position, wherein DAIs corresponding to other PDSCH subsets in the multiple PDSCH subsets except the first PDSCH subset ( see Fig. 8A, where PDSCH subset/group with C-DAI = 1 is regarded as first PDSCH subset) are derived based on a predefined rule (i.e. incremented based on the C-DAI of the first PDSCH subset/group being equal to 1, so the next PDSCH subset/group has a C-DAI = 2, and the following PDSCH subset/group has a C-DAI = 3, etc….) and the DAI corresponding to the first PDSCH subset. (See [Fig. 8A] where a first DAI indication field, C-DAI = 1, 2, or 3, indicates a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets, Also read where it recites “[0099] FIG. 8A illustrates a schematic diagram 800A illustrating an example generation of HARQ feedback during scheduling of multiple data channels by DCI in a CC according to embodiments of the present disclosure.

In regards to claim 7, The combination of Qualcomm in view of WANG teaches the method according to claim 1, wherein in a case that HARQ-ACK feedback is performed for the multiple PDSCH subsets at a single feedback position, the DCI comprises a second DAI indication field, and the second DAI indication field is used to indicate DAIs corresponding to at least two PDSCH subsets among the multiple PDSCH subsets. Qualcomm in view of WANG is believed to arrive at method of claim 1, for the reasons provided with respect to claim 1 above.

That is, there are 8 PDSCHs scheduled by one PDCCH, as shown by PDSCH #0 to #7 in FIG. 6, and there are 3 PDSCH groups in the DCI. With the above equations (1), (4) and (5), it is determined that PDSCH #0 and PDSCH #1 occupy Group #2 and PDSCH #3 occupy Group #1, and PDSCH #4, PDSCH #5, PDSCH #6 and PDSCH #7 occupy Group #2, as shown in FIG. 6…[0071] In these embodiments, the network device 120 may introduce one additional bit in the DCI to signal the number of data channels in each group (also referred to as a group size).

WANG further teaches with respect to the PDSCH subsets/groups, where a counting granularity of a DAI is the PDSCH group/subset (See [Fig. 12] where C-DAI counts the PDSCH group/subset), where the DCI comprises a second DAI indication field, and the second DAI indication field is used to indicate DAIs corresponding to at least two PDSCH subsets among the multiple PDSCH subsets.

The HARQ codebook may be generated first in ascending order of received multiple PDSCHs and then in ascending order of serving cell index and finally in ascending order of PDCCH monitoring occasions. This will be described in detail with reference to FIG. 12. [0124] FIG. 12 illustrates a schematic diagram 1200 illustrating an example generation of HARQ feedback during scheduling of multiple data channels by DCI in CA according to embodiments of the present disclosure. In this example, in the whole group of downlink data channels scheduled by DCI, c-DAIs for each downlink data channel in the whole group keep the same value as signaled in the DCI, and the t-DAI is used to judge if there is any missing detection in some PDCCH monitoring occasions. The terminal device 110 may generate 1 or 2 HARQ bits for each downlink data channel depending on the supported TB numbers in this cell. [0125] As shown in FIG. 12, in PDCCH monitoring occasion #0, i.e., slot #0, each of PDCCH 1210 in Pcell, PDCCH 1220 in Scan and PDCCH 1230 in Scell2 schedules four PDSCHs. The HARQ codebook may be concluded based on Table 4...”). WANG suggests performing these features in order to reduce the number bits required for encoding the downlink control information (DCI) (“[0060] According to embodiments of the present disclosure, the multiple data channels are divided into a plurality of groups, and one of bits in each of the NDI field and the RV field corresponds to one group among the plurality of groups.

Thus, based upon the teachings of WANG it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the feedback feature of Qualcomm by incorporating the PDSCH subset/group feature suggested by WANG, to arrive at claim 7. A person of ordinary skill in the art before the effective filing date of the claimed invention would have been motivated to make such a modification in order to reduce the number of bits required for encoding downlink control information (DCI).
In regards to claim 8, The combination of Qualcomm (Qualcomm Incorporated, “PDSCH and PUSCH enhancements for 52.6-71GHz band” cited in IDS received November 26, 2024) in view of WANG suggest the method according to claim 7, wherein the second DAI indication field is used to indicate the DAI corresponding to each PDSCH subset among the multiple PDSCH subsets. Regarding the method of claim 7, Qualcomm in view of WANG is believed to arrive at method of claim 7, for the reasons provided with respect to claim 7 above. With respect to the remaining feature(s) of claim 8, Qualcomm is silent on wherein the second DAI indication field is used to indicate the DAI corresponding to each PDSCH subset among the multiple PDSCH subsets. Despite these differences similar features have been seen in other prior art involving feedback for a physical downlink shared channel (PDSCH).
WANG for example teaches a feature for feedback that involves dividing into multiple PDSCH subsets, PDSCH groups, a PDSCH set scheduled by DCI, wherein a PDSCH subset comprises more than one PDSCH.

The HARQ codebook may be generated first in ascending order of received multiple PDSCHs and then in ascending order of serving cell index and finally in ascending order of PDCCH monitoring occasions. This will be described in detail with reference to FIG. 12. [0124] FIG. 12 illustrates a schematic diagram 1200 illustrating an example generation of HARQ feedback during scheduling of multiple data channels by DCI in CA according to embodiments of the present disclosure. In this example, in the whole group of downlink data channels scheduled by DCI, c-DAIs for each downlink data channel in the whole group keep the same value as signaled in the DCI, and the t-DAI is used to judge if there is any missing detection in some PDCCH monitoring occasions. The terminal device 110 may generate 1 or 2 HARQ bits for each downlink data channel depending on the supported TB numbers in this cell.

In regards to claim 16, Qualcomm teaches an information sending method, performed by a network side device, comprising:
sending at least one piece of downlink control information (DCI) to a terminal (See [2.2.4 Multi-PDSCH/PUSCH with single grant] “The design of multi-PDSCH scheduling with single DCI can leverage Rel.16 multi-PUSCH grant as much as possible, such as the following…”);
wherein the at least one piece of DCI is used by the terminal to divide, into multiple physical downlink shared channel (PDSCH) subsets, a PDSCH set scheduled by each DCI, determine a downlink assignment index (DAI) corresponding to each of the PDSCH subsets, and feed back a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the multiple PDSCH subsets according to the DAI corresponding to each of the PDSCH subsets, (See [2.2.4 Multi-PDSCH/PUSCH with single grant] “The design of multi-PDSCH scheduling with single DCI can leverage Rel.16 multi-PUSCH grant as much as possible, such as the following…”, “…For multi-PDSCH grant, we need to define new way to indicate DAI, to avoid the misalignment of the dynamic feedback codebooks between the UE and gNB in the case of misdetection of one of the multi-PDSCH grants.…”, “…For multi-PDSCH grant, we need to define new way to indicate DAI, to avoid the misalignment of the dynamic feedback codebooks between the UE and gNB in the case of misdetection of one of the multi-PDSCH grants.…”);
The feedback feature of Qualcomm differs from that of claim 16 in the following manner: (1) Qualcomm is silent on wherein a PDSCH subset comprises more than one PDSCH , (2) Qualcomm is silent on wherein a counting granularity of the DAI is the PDSCH subset (3) Qualcomm is silent on where a quantity of PDSCHs in each PDSCH subset is determined based on information predefined by a protocol, (4) Qualcomm is silent on wherein the feeding back the HARQ-ACK for the multiple PDSCH subsets comprises performing HARQ-ACK feedback for the multiple PDSCH subsets at a single feedback position and (5) Qualcomm is further silent on wherein the DCI satisfies that, in a case that the HARQ-ACK feedback is performed for the multiple PDSCH subsets at the single feedback position, the DCI comprises a first DAI indication field, the first DAI indication filed is used to indicate a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets. Despite these differences similar features have been seen in other prior art involving feedback for a physical downlink shared channel (PDSCH).
WANG for example teaches a feature for feedback that involves dividing into multiple PDSCH subsets, PDSCH groups, a PDSCH set scheduled by DCI, wherein a PDSCH subset comprises more than one PDSCH.

WANG further teaches with respect to the PDSCH subsets/groups, where a counting granularity of a DAI is the PDSCH group/subset (See [Fig. 8A] where C-DAI counts the PDSCH group/subset), where a quantity of PDSCHs in each PDSCH subset is determined based on information predefined by a protocol (See [Fig. 2] which illustrates a predefined relationship indicating a relationship between a quantity of PDSCHs in a PDSCH subset (i.e. PDSCH group size) and a Modulation and Coding Scheme), wherein the feeding back the HARQ-ACK for the multiple PDSCH subsets comprises performing HARQ-ACK feedback for the multiple PDSCH subsets at a single feedback position (See in [Fig. 8A] where the feedback for the PDSCH group indicated by C-DAI = 1, the PDSCH group indicated by C-DAI = 2, and the PDSCH group indicated by C-DAI = 3, is indicated by a single PUCCH or PUSCH) and wherein in a case that the HARQ-ACK feedback is performed for the multiple PDSCH subsets at the single feedback position, the DCI comprises a first DAI indication field, the first DAI indication field is used to indicate a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets (See [Fig. 8A] where a first DAI indication field, C-DAI = 1, 2, or 3,, indicates a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets, Also read where it recites “[0099] FIG. 8A illustrates a schematic diagram 800A illustrating an example generation of HARQ feedback during scheduling of multiple data channels by DCI in a CC according to embodiments of the present disclosure. In this example, in the whole group of downlink data channels scheduled by a single DCI, counter DAIs for each downlink data channel in the whole group keep the same value as signaled in the DCI. The terminal device 110 may generate 1 or 2 HARQ bits for each downlink data channel depending on the supported TB numbers in this cell.

WANG further teaches with respect to the PDSCH subsets/groups, where a counting granularity of a DAI is the PDSCH group/subset (See [Fig. 8A] where C-DAI counts the PDSCH group/subset), where a quantity of PDSCHs in each PDSCH subset is determined based on information predefined by a protocol (See [Fig. 2] which illustrates a predefined relationship indicating a relationship between a quantity of PDSCHs in a PDSCH subset (i.e. PDSCH group size) and a Modulation and Coding Scheme), wherein the feeding back the HARQ-ACK for the multiple PDSCH subsets comprises performing HARQ-ACK feedback for the multiple PDSCH subsets at a single feedback position (See in [Fig. 8A] where the feedback for the PDSCH group indicated by C-DAI = 1, the PDSCH group indicated by C-DAI = 2, and the PDSCH group indicated by C-DAI = 3, is indicated by a single PUCCH or PUSCH) and wherein in a case that the HARQ-ACK feedback is performed for the multiple PDSCH subsets at the single feedback position, the DCI comprises a first DAI indication field, the first DAI indication field is used to indicate a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets (See [Fig. 8A] where a first DAI indication field, C-DAI = 1, 2, or 3,, indicates a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets, Also read where it recites “[0099] FIG. 8A illustrates a schematic diagram 800A illustrating an example generation of HARQ feedback during scheduling of multiple data channels by DCI in a CC according to embodiments of the present disclosure. In this example, in the whole group of downlink data channels scheduled by a single DCI, counter DAIs for each downlink data channel in the whole group keep the same value as signaled in the DCI. The terminal device 110 may generate 1 or 2 HARQ bits for each downlink data channel depending on the supported TB numbers in this cell. A HARQ codebook may be generated in ascending order of the counter DAIs. [0100] As shown in FIG. 8A, PDCCH 810 schedules four PDSCHs, i.e., PDSCH #0 to #3, and the c-DAI in PDCCH 810 of slot #0 is 1. PDCCH 820 schedules two PDSCHs, i.e., PDSCH #4 and #5, and the c-DAI in PDCCH 820 of slot #4 is 2. PDCCH 830 schedules two PDSCHs, i.e., PDSCH #6 and #7, and the c-DAI in PDCCH 830 of slot #6 is 3. Assuming that the downlink data is received correctly on PDSCH #0 to #7. In case that 1 TB is supported, a HARQ codebook 840 may be generated. In case that 2 TBs are supported, a HARQ codebook 850 may be generated.”). WANG suggests performing these features in order to reduce the number bits required for encoding the downlink control information (DCI) (“[0060] According to embodiments of the present disclosure, the multiple data channels are divided into a plurality of groups, and one of bits in each of the NDI field and the RV field corresponds to one group among the plurality of groups. In other words, data channels within one group shares the same NDI and RV bits. In this way, the number of bits in DCI can be reduced significantly”)

A person of ordinary skill in the art before the effective filing date of the claimed invention would have been motivated to make such a modification in order to reduce the number of bits required for encoding downlink control information (DCI).
In regards to claim 19, Qualcomm (Qualcomm Incorporated, “PDSCH and PUSCH enhancements for 52.6-71GHz band” cited in IDS received November 26, 2024) teaches an information feedback method, performed by a terminal, comprising: teaches a terminal, comprising

[0060] According to embodiments of the present disclosure, the multiple data channels are divided into a plurality of groups, and one of bits in each of the NDI field and the RV field corresponds to one group among the plurality of groups. In other words, data channels within one group shares the same NDI and RV bits. In this way, the number of bits in DCI can be reduced significantly... [0068] FIG. 6 illustrates a schematic diagram 600 illustrating an example grouping of data channels scheduled by DCI according to embodiments of the present disclosure. In this example, C=8, and M=3. That is, there are 8 PDSCHs scheduled by one PDCCH, as shown by PDSCH #0 to #7 in FIG. 6, and there are 3 PDSCH groups in the DCI. With the above equations (1), (4) and (5), it is determined that PDSCH #0 and PDSCH #1 occupy Group #2 and PDSCH #3 occupy Group #1, and PDSCH #4, PDSCH #5, PDSCH #6 and PDSCH #7 occupy Group #2, as shown in FIG. 6…[0071] In these embodiments, the network device 120 may introduce one additional bit in the DCI to signal the number of data channels in each group (also referred to as a group size). DCI payload may be designed as below. [0072] DCI payload: [0073] multi-PDSCHs-grouping support—0 or 1 bit. [0074] 1 bit if the higher layer parameter multi-PDSCHs-Bundling-Flag is true. [0075] 0 bit otherwise. If multi-PDSCH-grouping support is 0, the network device 120 may set the group size=2, else if multi-PDSCH-grouping support is 1, the network device 120 may set the group size=4.”).
WANG further teaches with respect to the PDSCH subsets/groups, where a counting granularity of a DAI is the PDSCH group/subset (See [Fig. 8A] where C-DAI counts the PDSCH group/subset), wherein in a case that the HARQ-ACK feedback is performed for the multiple PDSCH subsets at the single feedback position, wherein DAIs corresponding to other PDSCH subsets in the multiple PDSCH subsets except the first PDSCH subset ( see Fig. 8A, where PDSCH subset/group with C-DAI = 1 is regarded as first PDSCH subset) are derived based on a predefined rule (i.e. incremented based on the C-DAI of the first PDSCH subset/group being equal to 1, so the next PDSCH subset/group has a C-DAI = 2, and the following PDSCH subset/group has a C-DAI = 3, etc….) and the DAI corresponding to the first PDSCH subset. (See [Fig. 8A] where a first DAI indication field, C-DAI = 1, 2, or 3, indicates a DAI corresponding to a first PDSCH subset, and the first PDSCH subset is one of the multiple PDSCH subsets, Also read where it recites “[0099] FIG. 8A illustrates a schematic diagram 800A illustrating an example generation of HARQ feedback during scheduling of multiple data channels by DCI in a CC according to embodiments of the present disclosure. In this example, in the whole group of downlink data channels scheduled by a single DCI, counter DAIs for each downlink data channel in the whole group keep the same value as signaled in the DCI. The terminal device 110 may generate 1 or 2 HARQ bits for each downlink data channel depending on the supported TB numbers in this cell. A HARQ codebook may be generated in ascending order of the counter DAIs. [0100] As shown in FIG. 8A, PDCCH 810 schedules four PDSCHs, i.e., PDSCH #0 to #3, and the c-DAI in PDCCH 810 of slot #0 is 1. PDCCH 820 schedules two PDSCHs, i.e., PDSCH #4 and #5, and the c-DAI in PDCCH 820 of slot #4 is 2. PDCCH 830 schedules two PDSCHs, i.e., PDSCH #6 and #7, and the c-DAI in PDCCH 830 of slot #6 is 3. Assuming that the downlink data is received correctly on PDSCH #0 to #7. In case that 1 TB is supported, a HARQ codebook 840 may be generated. In case that 2 TBs are supported, a HARQ codebook 850 may be generated.”). WANG suggests performing these features in order to reduce the number bits required for encoding the downlink control information (DCI) (“[0060] According to embodiments of the present disclosure, the multiple data channels are divided into a plurality of groups, and one of bits in each of the NDI field and the RV field corresponds to one group among the plurality of groups. In other words, data channels within one group shares the same NDI and RV bits. In this way, the number of bits in DCI can be reduced significantly”)
Thus, based upon the teachings of WANG it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the feedback feature of Qualcomm by incorporating the PDSCH subset/group feature suggested by WANG, to arrive at claim 22. A person of ordinary skill in the art before the effective filing date of the claimed invention would have been motivated to make such a modification in order to reduce the number of bits required for encoding downlink control information (DCI).
In regards to claim 23, the combination of Qualcomm (Qualcomm Incorporated, “PDSCH and PUSCH enhancements for 52.6-71GHz band” cited in IDS received November 26, 2024) in view of Wang suggests the terminal according to claim 19, wherein in a case that HARQ- ACK feedback is performed for the multiple PDSCH subsets at a single feedback position, the DCI comprises a second DAI indication field, and the second DAI indication field is used to indicate DAIs corresponding to at least two PDSCH subsets among the multiple PDSCH subsets. Regarding the terminal of claim 19, Qualcomm in view of WANG is believed to arrive at the terminal of claim 19, for the reasons provided with respect to claim 19 above. With respect to the remaining feature(s) of claim 23, Qualcomm is silent on wherein in a case that HARQ-ACK feedback is performed for the multiple PDSCH subsets at a single feedback position, the DCI comprises a second DAI indication field, and the second DAI indication field is used to indicate DAIs corresponding to at least two PDSCH subsets among the multiple PDSCH subsets. Despite these differences similar features have been seen in other prior art involving feedback for a physical downlink shared channel (PDSCH).
WANG for example teaches a feature for feedback that involves dividing into multiple PDSCH subsets, PDSCH groups, a PDSCH set scheduled by DCI, wherein a PDSCH subset comprises more than one PDSCH.
