These terms are only used to distinguish information of the same type from each other.

[0045] First, the relevant technologies involved in the embodiments of this application are introduced:

[0046] 1) Type 3 / enhanced Type 3 HARQ-ACK codebook:

[0047] The New Radio (NR) system supports feedback of Type-3 HARQ-ACK codebook and enhanced Type-3 HARQ-ACK codebook.

[0048] After the terminal device is configured to support feedback of the Type-3 HARQ-ACK codebook, the downlink control information (DCI) includes a one-shot HARQ-ACK request (One-shot HARQ-ACK Request) information field. If the one-shot HARQ-ACK request information field in the DCI received by the terminal device is set to "1", the terminal device generates a Type-3 HARQ-ACK codebook. The codebook includes HARQ-ACK information corresponding to all HARQ processes in all downlink carriers configured for the terminal device. If the frequency domain resource allocation (FDRA) information field in the DCI received by the terminal device indicates a valid value, the DCI not only triggers the terminal device to feedback the Type-3 HARQ-ACK codebook but also schedules PDSCH transmission. If the FDRA information field in the received DCI indicates an invalid value (for example, set to all 1s or all 0s), the DCI is only used to trigger the terminal device to feedback the Type-3 HARQ-ACK codebook without scheduling PDSCH transmission.

[0049] After the terminal device is configured to support feedback of the enhanced Type-3 HARQ-ACK codebook, the base station pre-configures M carrier sets or M HARQ process sets to the terminal device through high-layer signaling, and dynamically indicates one of the M carrier sets or M HARQ process sets through DCI. The enhanced Type-3 HARQ-ACK codebook fed back by the terminal device includes the HARQ-ACK feedback information of all HARQ processes in the carrier corresponding to the indicated set, or the HARQ-ACK feedback information of all HARQ processes corresponding to the indicated set. The DCI also includes the One-shot HARQ-ACK request information field. The specific triggering mechanisms include two types:

[0050] (1) The DCI also includes an Enhanced Type 3 Codebook Indicator information field, the bit length of which is equal to log2(M).

[0051] When the one-time HARQ-ACK request information field in the DCI received by the terminal device is set to 1, the enhanced Type 3 codebook indicator information field is used to indicate one of the pre-configured M sets, and the terminal device feeds back the HARQ-ACK feedback information of all HARQ processes corresponding to the one set.

[0052] (2) The enhanced Type 3 codebook indicator information field is not included in the DCI.

[0053] If the FDRA information field in the DCI received by the terminal device indicates a valid value, that is, the DCI schedules PDSCH transmission, the terminal device feeds back HARQ-ACK feedback information of all HARQ processes corresponding to the first set of the pre-configured M sets.

[0054] If the FDRA information field in the DCI received by the terminal device indicates an invalid value, that is, the DCI does not schedule PDSCH transmission, the modulation and coding scheme (MCS) information field in the DCI is used to indicate one of the pre-configured M sets, and the terminal device feeds back the HARQ-ACK feedback information of all HARQ processes corresponding to the one set.

[0055] 2) HARQ-ACK codebook retransmission:

[0056] In related technologies, NR systems support retransmission of the HARQ-ACK codebook. A terminal device cannot be configured to simultaneously feedback Type 3 / enhanced Type 3 HARQ-ACK codebooks and HARQ-ACK codebook retransmission.

[0057] For a terminal device configured with HARQ-ACK retransmission, when a DCI is received in time slot or sub-time slot n, and the one-time HARQ-ACK request information field in the DCI is set to 1, the DCI is not used to schedule PDSCH transmission, but is only used to trigger HARQ-ACK codebook retransmission. The terminal device determines an integer l in the range of -7 to 24 based on the MCS information field in the DCI, and further determines the Type-1 HARQ-ACK codebook (i.e., semi-static HARQ-ACK codebook) or Type-2 HARQ-ACK codebook (i.e., dynamic HARQ-ACK codebook) in the retransmission time slot or sub-time slot s = ml.

[0058] 3) Multi-Carrier Scheduling:

[0059] In the "Multi-Carrier" project, the feature of supporting one DCI to schedule PDSCH / PUSCH of multiple cells is supported. Specifically, according to the pre-configured scheduling relationship, one DCI can be used to schedule PDSCH / PUSCH in up to N cells. According to actual scheduling requirements, one DCI can only schedule PDSCH / PUSCH transmission on part of the N cells at a time, instead of having to schedule all N cells. In related technologies, such DCI may include a common one-time HARQ-ACK request information field set based on the N cells, while other information fields, such as MCS information field, FDRA information field, Time Domain Resource Assignment (TDRA) information field, etc., can be independently set based on part of the N cells.

[0060] However, since the number of bits required for DCI supporting multi-carrier scheduling is large, that is, the overhead required for DCI supporting multi-carrier scheduling is large, when using DCI supporting multi-carrier scheduling to trigger feedback Type 3 / enhanced Type 3 HARQ-ACK codebook or HARQ-ACK codebook retransmission, it is necessary to take into account issues such as control signaling overhead, scheduling efficiency, and triggering flexibility.

[0061] Therefore, the present application provides a method for determining feedback information, which determines the HARQ-ACK codebook to be fed back by using the target information field corresponding to the first unscheduled cell in the unscheduled cells, thereby effectively reducing the overhead required for DCI and improving scheduling flexibility and scheduling efficiency.

[0062] Fig. 1 shows a schematic diagram of a system for determining feedback information provided by an exemplary embodiment of the present application.

[0076] In some embodiments, the first DCI is used to schedule M cells out of N cells, the target information field is not used to indicate configuration information of the M cells, N is an integer greater than 1, and M is an integer.

For example, when the value of the first information field is 1, it indicates that the HARQ-ACK codebook is fed back; when the value of the first information field is 0, it indicates that the HARQ-ACK codebook is not fed back.

[0081] FIG3 is a flow chart of a method for determining feedback information provided by some exemplary embodiments of the present application. This method is illustrated by taking the terminal device 120 shown in FIG1 as an example. The method includes at least some of the following steps:

[0082] Step 310: Receive a first DCI, where the first DCI includes a first information field and a target information field;

[0083] In some embodiments, the first DCI is used to schedule a scheduled cell among N cells, where N is an integer greater than 1.

[0086] In some embodiments, the first DCI is used to schedule a scheduled cell among N cells, and the target information field corresponds to a first unscheduled cell among the unscheduled cells among the N cells.

[0087] In some embodiments, the first DCI is used to schedule M cells out of N cells, the target information field is not used to indicate configuration information of the M cells, N is an integer greater than 1, and M is an integer.

[0088] In some embodiments, the target information field is an information field corresponding to the first unscheduled cell; wherein the first unscheduled cell is a cell with the largest cell index or the smallest cell index among the unscheduled cells.

[0094] In some embodiments, the unscheduled cell is determined based on a second information field in the first DCI, where the second information field is used to indicate a scheduled cell among the N cells.

[0101] In some embodiments, when the first information field indicates a feedback enhanced type 3 HARQ-ACK codebook, a carrier set or a HARQ process set corresponding to the HARQ-ACK codebook to be fed back is determined based on the target information field.

[0102] In some embodiments, the carrier set or HARQ process set corresponding to the HARQ-ACK codebook to be fed back is one of K sets, where K is an integer greater than or equal to 1; the K sets are K carrier sets or K HARQ process sets configured by the network device.

[0104] In some embodiments, when the number of unscheduled cells is zero, that is, when there are no scheduled cells, the HARQ-ACK codebook to be fed back is determined based on the first set or the last set of the K sets, where K is an integer greater than or equal to 1; the K sets are K carrier sets or K HARQ process sets configured by the network device.

[0105] In summary, the method provided in this embodiment, when receiving the first DCI for scheduling a scheduled cell among N cells, determines the HARQ-ACK codebook to be fed back by the target information field corresponding to the first unscheduled cell among the unscheduled cells, thereby reducing the resource overhead of the first DCI when triggering the terminal device to feedback the HARQ-ACK codebook, and improving the scheduling efficiency of the first DCI.

[0113] In some embodiments, the target information field is an information field corresponding to the first unscheduled cell; wherein the first unscheduled cell is a cell with the largest cell index or the smallest cell index among the unscheduled cells.

[0114] In some embodiments, the target information field is an information field corresponding to the first unscheduled cell, and the information field corresponding to the first unscheduled cell includes at least one of the following information fields:

[0115] MCS domain;

[0116] ·TDRA domain;

[0117] ·FDRA domain;

[0118] The first unscheduled cell is a cell with the largest cell index or the smallest cell index among the unscheduled cells.

[0119] In some embodiments, the unscheduled cell is determined based on a second information field in the first DCI, where the second information field is used to indicate a scheduled cell among the N cells.

[0120] In some embodiments, the second information field indicates that the number of scheduled cells in N cells is zero, that is, there are no scheduled cells in the N cells; or, the second information field indicates that the number of scheduled cells in N cells is greater than 0 and less than N, that is, greater than 0 and less than N cells are scheduled in the N cells; or, the second information field indicates that the number of scheduled cells in N cells is N, that is, all N cells are scheduled.

[0121] In some embodiments, the unscheduled cell is determined based on the second information field and the third information field in the first DCI; wherein the second information field is used to indicate the scheduled cell among the N cells, and the third information field is used to indicate the time domain resource allocation information and / or frequency domain resource allocation information of the scheduled cell.

[0122] In some embodiments, the third information field is different from the target information field.

[0123] In some embodiments, when the third information domain is used to indicate the time domain resource allocation information of the scheduled cell, the target information domain is not the TDRA domain, for example, the target information domain is the MCS domain and / or the FDRA domain; when the third information domain is used to indicate the frequency domain resource allocation information of the scheduled cell, the target information domain is not the FDRA domain, for example, the target information domain is the MCS domain and / or the TDRA domain; when the third information domain is used to indicate the time domain resource allocation information and the frequency domain resource allocation information of the scheduled cell, the target information domain is neither the TDRA domain nor the FDRA domain, for example, the target information domain is the MCS domain.

[0124] In some embodiments, the first information field is a one-time HARQ-ACK request information field.

[0125] In some embodiments, when the value of the first information field is a first value, it indicates that the HARQ-ACK codebook is retransmitted; when the value of the first information field is a second value, it indicates that the HARQ-ACK codebook is not retransmitted. For example, when the value of the first information field is 1, it indicates that the HARQ-ACK codebook is retransmitted; when the value of the first information field is 0, it indicates that the HARQ-ACK codebook is not retransmitted.

[0126] In some embodiments, when the first information field indicates a retransmission HARQ-ACK codebook, the HARQ-ACK codebook corresponding to the first time domain unit included in the HARQ-ACK codebook to be fed back is determined based on the target information field.

[0127] In some embodiments, the first time domain unit is determined based on the first DCI and the target information field.

[0128] In some embodiments, the first time domain unit is determined based on the time domain unit of receiving the first DCI and a value determined based on the target information field.

[0129] In some embodiments, the first time domain unit s is determined based on the difference between the time domain unit m and the value l, or the first time domain unit s is determined based on the sum of the time domain unit m and the value l. The time domain unit m is the time domain unit for receiving the first DCI, and m is an integer; the value l is determined based on the target information field, and l is an integer greater than or equal to -7 and less than or equal to 24, that is, -7≤l≤24.

[0130] In some embodiments, the HARQ-ACK codebook to be fed back further includes: HARQ-ACK information corresponding to a scheduled cell among the N cells; the scheduled cell is a cell among the N cells excluding an unscheduled cell.

[0131] In some embodiments, the time domain unit includes at least one of a time slot and a sub-time slot.

[0132] In summary, the method provided in this embodiment, when receiving the first DCI for scheduling a scheduled cell among N cells, determines the HARQ-ACK codebook corresponding to the first time domain unit included in the HARQ-ACK codebook to be fed back through the target information field corresponding to the first unscheduled cell among the unscheduled cells, thereby reducing the resource overhead of the first DCI when triggering the terminal device to feedback the HARQ-ACK codebook, and improving the scheduling efficiency of the first DCI. Moreover, compared with the related art, when the first DCI is used to trigger the retransmission of the HARQ-ACK codebook and the PDSCH cannot be scheduled, the method provided in this embodiment effectively improves the scheduling flexibility and scheduling efficiency of the first DCI.

[0133] FIG5 is a flow chart of a method for determining feedback information provided by some exemplary embodiments of the present application. The method is illustrated by taking the terminal device 120 shown in FIG1 as an example. The method includes at least some of the following steps:

[0134] Step 510: Receive a first DCI;

[0135] The first DCI is used to schedule a scheduled cell among N cells, where N is an integer greater than 1.

[0136] In some embodiments, the first DCI schedules no cell, that is, the number of scheduled cells is 0, which can be understood as there is no scheduled cell; or, the first DCI schedules at least one cell, that is, the number of scheduled cells is at least one, which can be understood as there is at least one scheduled cell.

[0137] In some embodiments, the first DCI is used to schedule the PDSCH / PUSCH of a scheduled cell among N cells. This embodiment is schematically described by taking the example of the first DCI being used to schedule the PDSCH of a scheduled cell among N cells.

[0138] The first DCI includes a first information field, where the first information field is a one-time HARQ-ACK request information field.

[0139] In some embodiments, the first DCI further includes a second information field. The unscheduled cell is determined based on the second information field in the first DCI, and the second information field is used to indicate the scheduled cell among the N cells. The second information field may indicate 2 T -1 combination of scheduled cells, where T is the bit length of the second information field.

[0140] In some embodiments, the first DCI further includes a second information field and a third information field. The unscheduled cell is determined based on the second information field and the third information field in the first DCI; wherein the second information field is used to indicate the scheduled cell among the N cells, and the third information field is used to indicate the time domain resource allocation information and / or frequency domain resource allocation information of the scheduled cell. The second information field can indicate 2 T combinations of scheduled cells, where T is the bit length of the second information field.

[0141] Step 530: Determine the HARQ-ACK codebook to be fed back.

[0142] When the value of the first information field is the first value, it indicates that the terminal device feeds back a type 3 HARQ-ACK codebook.

[0143] Exemplarily, N is 4, that is, the first DCI is used to schedule the scheduled cell among the four cells: cell 0, cell 1, cell 2, and cell 3.

[0144] The first DCI includes a 1-bit first information field, and the value of the first information field is "1", indicating that the terminal device feeds back a type 3 HARQ-ACK codebook.

[0145] In some embodiments, the first DCI further includes a second information field.

[0146] For example, the second information field occupies 3 bits and is used to indicate that no cell is scheduled, that is, the number of scheduled cells is 0. Then the first DCI is used to trigger the feedback of the type 3 HARQ-ACK codebook, but is not used to schedule PDSCH transmission.

[0147] For another example, the second information field occupies 3 bits and is used to indicate scheduling of cell 1. Then, in addition to being used to trigger feedback of the type 3 HARQ-ACK codebook, the first DCI is also used to schedule PDSCH transmission of cell 1.

[0148] In some embodiments, the first DCI also includes a second information field and a third information field. The second information field is used to indicate the scheduled cell among the N cells and occupies 3 bits. As shown in Table 1, the third information field is used to indicate the frequency domain resource allocation information of the scheduled cell, that is, the third information field is the FDRA information field and occupies 4 bits.

[0149] Table 1 The third information field

[0150] Cell FDRA information field 0 FDRA information field 01 FDRA information field 12 FDRA information field 23 FDRA information field 3

[0151] For example, the second information field is used to indicate scheduling for cell 1. Based on the frequency domain resource allocation information shown in Table 1, the value of the FDRA information field 1 corresponding to cell 1 is invalid, for example, the value of the FDRA information field 1 corresponding to cell 1 is set to all 1s or all 0s. The first DCI is used to trigger feedback of the type 3 HARQ-ACK codebook but does not schedule PDSCH transmission.

[0152] For another example, the second information field is used to indicate scheduling of cell 0 and cell 1. Based on the frequency domain resource allocation information shown in Table 1, the value of FDRA information field 1 corresponding to cell 1 is an invalid value, and the value of FDRA information field 1 corresponding to cell 0 is a valid value. The first DCI is used to trigger feedback of the type 3 HARQ-ACK codebook and to schedule PDSCH transmission of cell 0.

[0153] In some embodiments, the first DCI also includes a second information field and a third information field. The second information field is used to indicate the scheduled cell among the N cells and occupies 3 bits. As shown in Table 2, the third information field is used to indicate the frequency domain resource allocation information of the scheduled cell, that is, the third information field is the FDRA information field and occupies 2 bits.

[0154] Table 2 The third information field

[0155]

[0156] For example, the second information field is used to indicate scheduling of cell 1. Based on the frequency domain resource allocation information shown in Table 2, the value of FDRA information field 0 corresponding to cell 1 is an invalid value. Then the first DCI is used to trigger feedback of the type 3 HARQ-ACK codebook, but does not schedule PDSCH transmission.

[0157] For another example, the second information field is used to indicate the scheduling of cell 1 and cell 2. Based on the frequency domain resource allocation information shown in Table 2, the value of FDRA information field 0 corresponding to cell 1 is a valid value, and the value of FDRA information field 1 corresponding to cell 2 is an invalid value. The first DCI is used to trigger feedback of the type 3 HARQ-ACK codebook and to schedule PDSCH transmission of cell 1.

[0158] In summary, the method provided in this embodiment, when receiving a first DCI for scheduling a scheduled cell among N cells, determines the cell scheduled by the first DCI using the HARQ-ACK codebook to be fed back in the first information field; determines the cell scheduled by the first DCI using the second information field, or using the second information field and the third information field, thereby improving the scheduling efficiency of the first DCI. Since the triggering of HARQ-ACK codebook feedback does not need to be strongly related to cell scheduling, the scheduling flexibility of the first DCI is further improved.

[0159] FIG6 is a flow chart of a method for determining feedback information provided by some exemplary embodiments of the present application. This method is illustrated by taking the terminal device 120 shown in FIG1 as an example. The method includes at least some of the following steps:

[0160] Step 610: Receive configurations of K sets;

[0161] The K sets are K carrier sets or K HARQ process sets configured by the network device, where K is an integer greater than or equal to 1. In some embodiments, the set numbers in the K sets range from 0 to K-1, or from 1 to K.

[0162] Exemplarily, the terminal device receives a configuration of three HARQ process sets, for example, the three sets are HARQ process set 0, HARQ process set 1 and HARQ process set 2.

[0163] Step 630: Receive a first DCI;

[0164] The first DCI is used to schedule a scheduled cell among N cells, where N is an integer greater than 1.

[0165] In some embodiments, the first DCI schedules no cell, that is, the number of scheduled cells is 0, which can be understood as there is no scheduled cell; or, the first DCI schedules at least one cell, that is, the number of scheduled cells is at least one, which can be understood as there is at least one scheduled cell.

[0166] In some embodiments, the first DCI is used to schedule the PDSCH / PUSCH of a scheduled cell among N cells. This embodiment is schematically described by taking the example of the first DCI being used to schedule the PDSCH of a scheduled cell among N cells.

[0167] In some embodiments, the first DCI includes a first information field, wherein the first information field is a one-time HARQ-ACK request information field.

[0168] In some embodiments, the first DCI includes a first information field and a target information field, wherein the first information field is a one-time HARQ-ACK request information field.

[0169] In some embodiments, the target information field is a portion of the information field corresponding to the non-scheduled cells among the N cells.

[0170] In some embodiments, the target information field corresponds to a first unscheduled cell among the N unscheduled cells.

[0171] In some embodiments, the first DCI is used to schedule M cells out of N cells, the target information field is not used to indicate configuration information of the M cells, N is an integer greater than 1, and M is an integer.

[0172] In some embodiments, the unscheduled cells are determined based on the second information field in the first DCI, and the second information field is used to indicate the scheduled cells among the N cells. The second information field may indicate 2 T -1 combination of scheduled cells, where T is the bit length of the second information field.

[0173] In some embodiments, the unscheduled cell is determined based on the second information field and the third information field in the first DCI; wherein the second information field is used to indicate the scheduled cell among the N cells, and the third information field is used to indicate the time domain resource allocation information and / or frequency domain resource allocation information of the scheduled cell. The second information field may indicate 2 T combinations of scheduled cells, where T is the bit length of the second information field.

[0174] In some embodiments, the target information field is an information field corresponding to the first unscheduled cell, and the information field corresponding to the first unscheduled cell includes at least one of the following information fields:

[0175] MCS domain;

[0176] ·TDRA domain;

[0177] ·FDRA domain;

[0178] The first unscheduled cell is a cell with the largest cell index or the smallest cell index among the unscheduled cells.

[0179] In some embodiments, the third information field is different from the target information field.

[0180] Step 650: Determine the carrier set or HARQ process set corresponding to the HARQ-ACK codebook to be fed back.

[0181] When the value of the first information field is the first value, it indicates that the terminal device feeds back an enhanced type 3 HARQ-ACK codebook.

[0182] Exemplarily, N is 4, that is, the first DCI is used to schedule the scheduled cell among the four cells: cell 0, cell 1, cell 2, and cell 3.

[0183] The first DCI includes a 1-bit first information field, and the value of the first information field is "1", indicating that the terminal device feeds back an enhanced type 3 HARQ-ACK codebook.

[0184] The following discusses how to determine the carrier set or HARQ process set corresponding to the HARQ-ACK codebook to be fed back, divided into two cases.

[0185] Case 1: The first DCI does not schedule all of the N cells

[0186] In case 1, that is, when there is an unscheduled cell among the N cells, the carrier set or HARQ process set corresponding to the HARQ-ACK codebook to be fed back is determined based on the target information field.

[0187] In some embodiments, the first DCI further includes a 3-bit second information field, and the second information field indicates scheduled cell 1. The unscheduled cells are cell 0, cell 2, and cell 3. The first unscheduled cell is the cell with the smallest cell index among cell 0, cell 2, and cell 3, that is, cell 0; or the first unscheduled cell is the cell with the largest cell index among cell 0, cell 2, and cell 3, that is, cell 3.

[0188] The first DCI also includes a 2-bit third information field, as shown in Table 3. The third information field is a TDRA information field, which is used to indicate the TDRA information of cells 0, 1, 2, and 3. Based on the TDRA information shown in Table 3, the value of TDRA information field 0 corresponding to cell 1 is a valid value.

[0189] Table 3 The third information field

[0190]

[0191] Since the third information field is the TDRA information field, the target information field is the MCS information field of the first unscheduled cell and / or the FDRA information field of the first unscheduled cell. This embodiment is schematically described using the MCS information field of the first unscheduled cell as an example.

[0192] The first DCI also includes a 4-bit MCS information field, which is used to indicate the MCS information of cell 0, cell 1, cell 2, and cell 3, as shown in Table 4.

[0193] Table 4 Target information fields

[0194] Cell MCS Information Field 0 MCS Information Field 01 MCS Information Field 12 MCS Information Field 23 MCS Information Field 3

[0195] The target information field is the MCS information field 0 corresponding to cell 0, or the target information field is the MCS information field 3 corresponding to cell 3. This embodiment is schematically described by taking the MCS information field 0 corresponding to cell 0 as an example.

[0196] Based on the value of the target information field, one of the K sets configured for the network device is determined. Specifically, based on the value of MCS information field 0 corresponding to cell 0, one of the three HARQ process sets configured for the network device is determined. For example, based on the value of MCS information field 0 corresponding to cell 0, HARQ process set 1 is determined to be configured for the network device.

[0197] The first DCI is used to trigger feedback of an enhanced type 3 HARQ-ACK codebook, which includes HARQ-ACK information corresponding to all HARQ processes in HARQ process set 1, and the first DCI is used to schedule PDSCH transmission of cell 1.

[0198] Case 2: The first DCI schedules all N cells

[0199] In case 2, that is, when there is no scheduled cell in the N cells, the target information field corresponds to at least one scheduled cell in the N cells, and the carrier set or HARQ process set corresponding to the HARQ-ACK codebook to be fed back can be determined by the default rule.

[0200] In some embodiments, the terminal device generates an enhanced type 3 HARQ-ACK codebook according to HARQ-ACK information corresponding to the first set or the last set among the K sets.

[0201] In some embodiments, the first DCI further includes a 3-bit second information field, and the second information field indicates the scheduling of cell 0, cell 1, cell 2, and cell 3. Based on the TDRA information field shown in Table 3, the value of TDRA information field 0 corresponding to cell 0 and cell 1 is a valid value, and the value of TDRA information field 0 corresponding to cell 2 and cell 3 is a valid value. The indication result of the second information field and the third information field is that the first DCI indicates the scheduling of the PDSCH corresponding to cell 0, cell 1, cell 2, and cell 3, that is, the first DCI indicates the scheduling of all cells in N cells.

[0202] The first DCI is used to trigger feedback of an enhanced type 3 HARQ-ACK codebook, where the enhanced type 3 HARQ-ACK codebook includes HARQ-ACK information corresponding to all HARQ processes in HARQ process set 0 (i.e., the first set of K sets), or the enhanced type 3 HARQ-ACK codebook includes HARQ-ACK information corresponding to all HARQ processes in HARQ process set 2 (i.e., the last set of K sets). And the first DCI is used to schedule PDSCH transmission of cell 1.

[0203] To summarize, the method provided in this embodiment, when receiving the first DCI for scheduling a scheduled cell among N cells, determines the carrier set or HARQ process set corresponding to the HARQ-ACK codebook to be fed back through the target information field corresponding to the first unscheduled cell among the unscheduled cells, thereby reducing the resource overhead of the first DCI when triggering the terminal device to feedback the HARQ-ACK codebook, and improving the scheduling efficiency and scheduling flexibility of the first DCI.

[0204] FIG7 is a flow chart showing a method for determining feedback information provided by some exemplary embodiments of the present application. The method is illustrated by taking the terminal device 120 shown in FIG1 as an example. The method includes at least some of the following steps:

[0205] Step 710: Receive a first DCI;

[0206] The first DCI is used to schedule a scheduled cell among N cells, where N is an integer greater than 1.

[0207] In some embodiments, the first DCI schedules no cell, that is, the number of scheduled cells is 0, which can be understood as there is no scheduled cell; or, the first DCI schedules at least one cell, that is, the number of scheduled cells is at least one, which can be understood as there is at least one scheduled cell.

[0208] In some embodiments, the terminal device receives the first DCI in time slot m. Exemplarily, m is an integer.

[0209] In some embodiments, the terminal device starts receiving the first DCI at time slot m, and / or the terminal device ends receiving the first DCI at time slot m.

[0210] In some embodiments, the first DCI is used to schedule the PDSCH / PUSCH of at least one cell among the N cells. This embodiment is schematically described by taking the example of the first DCI being used to schedule the PDSCH of at least one cell among the N cells.

[0211] In some embodiments, the unscheduled cells are determined based on the second information field in the first DCI, and the terminal device does not expect that the scheduled cells indicated by the second information field are all of the N cells, that is, the number of scheduled cells indicated by the second information field is less than N.

[0212] In some embodiments, the unscheduled cells are determined based on the second information field and the third information field in the first DCI, and the terminal device does not expect the indication result of the second information field and the third information field to be that the scheduled cells are all of the N cells, that is, the number of scheduled cells jointly indicated by the second information field and the third information field is less than N.

[0213] In some embodiments, the first DCI includes a first information field and a target information field, wherein the first information field is a one-time HARQ-ACK request information field.

[0214] In some embodiments, the target information field is a portion of the information field corresponding to the non-scheduled cells among the N cells.

[0215] In some embodiments, the target information field corresponds to a first unscheduled cell among the N unscheduled cells.

[0216] In some embodiments, the first DCI is used to schedule M cells out of N cells, the target information field is not used to indicate configuration information of the M cells, N is an integer greater than 1, and M is an integer.

[0217] In some embodiments, the unscheduled cells are determined based on the second information field in the first DCI, and the second information field is used to indicate the scheduled cells among the N cells. The second information field may indicate 2 T -1 combination of scheduled cells, where T is the bit length of the second information field.

[0218] In some embodiments, the unscheduled cell is determined based on the second information field and the third information field in the first DCI; wherein the second information field is used to indicate the scheduled cell among the N cells, and the third information field is used to indicate the time domain resource allocation information and / or frequency domain resource allocation information of the scheduled cell. The second information field may indicate 2 T -1 combination of scheduled cells, where T is the bit length of the second information field.

[0219] In some embodiments, the target information field is an information field corresponding to the first unscheduled cell, and the information field corresponding to the first unscheduled cell includes at least one of the following information fields:

[0220] MCS domain;

[0221] ·TDRA domain;

[0222] ·FDRA domain;

[0223] The first unscheduled cell is a cell with the largest cell index or the smallest cell index among the unscheduled cells.

[0224] In some embodiments, the third information field is different from the target information field.

[0225] Step 730: Based on the target information field, determine the HARQ-ACK codebook corresponding to the first time domain unit included in the HARQ-ACK codebook to be fed back.

[0226] When the value of the first information field is the first value, it instructs the terminal device to retransmit the HARQ-ACK codebook.

[0227] Exemplarily, N is 4, that is, the first DCI is used to schedule at least one of the four cells: cell 0, cell 1, cell 2, and cell 3.

[0228] The first DCI includes a 1-bit first information field, and the value of the first information field is "1", indicating that the terminal device retransmits the HARQ-ACK codebook.

[0229] The first DCI also includes a 3-bit second information field, and the second information field indicates scheduled cell 1. The unscheduled cells are cell 0, cell 2, and cell 3. The first unscheduled cell is the cell with the smallest cell index among cells 0, cell 2, and cell 3, that is, cell 0; or the first unscheduled cell is the cell with the largest cell index among cells 0, cell 2, and cell 3, that is, cell 3.

[0230] The first DCI also includes a 2-bit third information field, as shown in Table 3. The third information field is a TDRA information field, which is used to indicate the TDRA information of cells 0, 1, 2, and 3. Based on the TDRA information shown in Table 3, the value of TDRA information field 0 corresponding to cell 1 is a valid value.

[0231] Since the third information field is the TDRA information field, the target information field is the MCS information field of the first unscheduled cell and / or the FDRA information field of the first unscheduled cell. This embodiment is schematically described using the MCS information field of the first unscheduled cell as an example.

[0232] The first DCI also includes a 4-bit MCS information field, which is used to indicate the MCS information of cell 0, cell 1, cell 2, and cell 3, as shown in Table 4.

[0233] The target information field is the MCS information field 0 corresponding to cell 0, or the target information field is the MCS information field 3 corresponding to cell 3. This embodiment is schematically described by taking the case where the target information field is the MCS information field 3 corresponding to cell 3 as an example.

[0234] According to the value of the target information field, that is, according to the value of the MCS information field 3 corresponding to the cell 3, an integer having a value of 1 is determined, where -7≤1≤24.

[0235] The first time domain unit s is determined based on the difference between the time domain unit m of the received first DCI and the value l. That is, s=ml, where s is an integer.

[0236] The first time domain unit s is determined based on the sum of the time domain unit m of the received first DCI and the value l. That is, s=m+l, where s is an integer.

[0237] The HARQ-ACK codebook to be fed back triggered by the first DCI includes the HARQ-ACK codebook corresponding to the first time domain unit s, and also includes the HARQ-ACK information corresponding to cell 1 scheduled by the first DCI. The first DCI is also used to schedule PDSCH transmission of cell 1.

[0238] In some embodiments, in the HARQ-ACK codebook to be fed back triggered by the first DCI, the bits occupied by the HARQ-ACK codebook corresponding to the first time domain unit s are after the bits occupied by the HARQ-ACK information corresponding to cell 1.

[0239] In some embodiments, the HARQ-ACK codebook corresponding to the first time domain unit s is a Type-1 HARQ-ACK codebook, i.e., a semi-static HARQ-ACK codebook; or a Type-2 HARQ-ACK codebook, i.e., a dynamic HARQ-ACK codebook.

[0240] In some embodiments, the time domain unit includes at least one of a time slot and a sub-time slot.

[0241] In summary, the method provided in this embodiment, when receiving the first DCI for scheduling a scheduled cell among N cells, determines the HARQ-ACK codebook corresponding to the first time domain unit included in the HARQ-ACK codebook to be fed back through the target information field corresponding to the first unscheduled cell among the unscheduled cells, thereby reducing the resource overhead of the first DCI when triggering the terminal device to feedback the HARQ-ACK codebook, and improving the scheduling efficiency of the first DCI. Moreover, compared with the related art, when the first DCI is used to trigger the retransmission of the HARQ-ACK codebook and the PDSCH cannot be scheduled, the method provided in this embodiment effectively improves the scheduling flexibility and scheduling efficiency of the first DCI.

[0242] FIG8 is a flow chart showing a method for determining feedback information provided by some exemplary embodiments of the present application. The method is illustrated by taking the network device 110 shown in FIG1 as an example. The method includes at least some of the following steps:

[0243] Step 810: Send a first DCI, where the first DCI includes a first information field and a target information field.

[0244] In some embodiments, the first DCI is used to schedule a scheduled cell among N cells, where N is an integer greater than 1.

[0245] In some embodiments, the first DCI schedules no cell, that is, the number of scheduled cells is 0, which can be understood as there is no scheduled cell; or, the first DCI schedules at least one cell, that is, the number of scheduled cells is at least one, which can be understood as there is at least one scheduled cell.

[0246] In some embodiments, the first DCI further includes a second information field for indicating a scheduled cell among the N cells.

[0247] In some embodiments, the first DCI further includes a second information field and a third information field, wherein the second information field is used to indicate a scheduled cell among the N cells, and the third information field is used to indicate time domain resource allocation information and / or frequency domain resource allocation information of the scheduled cell.
