Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus, and readable storage medium for determining or decoding a HARQ-ACK codebook. Background Technology

[0002] Type 1 codebook is a fixed-size HARQ-ACK feedback method that uses a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook. On a HARQ-ACK physical uplink control channel (PUCCH), it is necessary to feed back HARQ-ACKs for all valid candidate physical downlink shared channels (PDSCH) on all time slots within a fixed-size feedback window.

[0003] In the NR 52.6-71GHz range, a scenario will be introduced where multiple PDSCH slots are scheduled via the Physical Downlink Control channel (PDCCH), i.e., a multi-slot PDSCH scheduling scenario. Due to the introduction of multi-slot PDSCH scheduling, determining the Type 1 codebook feedback window solely based on the K1 set in a single-slot scheduling scenario may result in the Type 1 codebook not completely encompassing all PDSCH slots scheduled by the Downlink Control Information (DCI).

[0004] For multi-slot PDSCH scheduling, a HARQ-ACK bundling feedback method is proposed. That is, for N1 PDSCHs scheduled by a DCI, originally N1 HARQ-ACK messages would be fed back, but after HARQ-ACK bundling, only N2 HARQ-ACK messages need to be fed back, where N2 <N1。

[0005] How to determine the K1 set of the Type 1 codebook using the HARQ-ACK bundling feedback method is a technical problem that needs to be solved. Summary of the Invention

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0094] like Figure 1 As shown, Figure 1 This is a schematic diagram of a communication system according to an exemplary embodiment. The method for determining the HARQ-ACK codebook provided in this disclosure can be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. The user equipment 101 is configured to support carrier aggregation and can be connected to multiple carrier units of the network device 102, including a primary carrier unit and one or more secondary carrier units.

[0095] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios. Application scenarios for the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0096] The user equipment (UE) 101 shown above can be a terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication equipment, terminal agent, or user equipment, etc. The UE 101 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices in one or more communication systems and receive network services provided by the network devices. These network devices include, but are not limited to, the network device 102 shown in the figure.

[0097] User equipment 101 may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, user equipment in a future 5G network or user equipment in a future evolved PLMN network, etc.

[0098] Network device 102 can be an access network device (or access point). Access network device refers to equipment that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device 102 may include a base station (BS), or a base station and radio resource management equipment used to control the base station. Network device 102 may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations.

[0099] For example, network equipment 102 includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved nodeB, or home node B, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.

[0100] In a multi-slot PDSCH scheduling scenario, HARQ-ACKs for multiple PDSCHs scheduled by a single DCI are fed back within the same PUCCH. The PUCCH slot for HARQ-ACK feedback for these multiple PDSCHs is determined based on k1 in the scheduling DCI and the slot position of the last PDSCH. However, due to the introduction of multi-slot PDSCH scheduling, determining the Type1 codebook feedback window solely based on the K1 set in a single-slot scheduling scenario may result in the Type1 codebook not completely encompassing the slots containing all PDSCHs scheduled by the DCI.

[0101] When using multi-TTI PDSCH scheduling and HARQ-ACK bundling feedback methods simultaneously, it may not be guaranteed that regardless of any k1 value indicated by the scheduling DCI from the configured K1 set, multiple PDSCHs scheduled by the DCI will be able to feed back a Type 1 HARQ-ACK codebook on a single HARQ-ACK PUCCH resource.

[0102] This disclosure presents a method for determining the extended K1 set of the Type 1 HARQ-ACK codebook for multi-TTI PDSCH scheduling and HARQ-ACK bundling feedback. This method can obtain, under HARQ-ACK bundling feedback, the minimum extended K1 set (i.e., the extended K1 set with the fewest included k1 values) that guarantees that regardless of any k1 value indicated by the scheduling DCI from the configured K1 set, multiple PDSCHs scheduled by the DCI can provide feedback of the Type 1 HARQ-ACK codebook on a single HARQ-ACK PUCCH resource.

[0103] This disclosure provides a method for feeding back a HARQ-ACK codebook, applied to a communication system 100. (Refer to...) Figure 2 , Figure 2 This is a flowchart illustrating a method for determining a HARQ-ACK codebook according to an exemplary embodiment, such as... Figure 2 As shown, this method includes:

[0106] Step S23, User Equipment 101 determines the HARQ-ACK codebook based on the second K1 set;

[0107] Step S24, User Equipment 101 determines the feedback window of the HARQ-ACK codebook based on the second K1 set;

[0108] Step S25, user equipment 101 feeds back the HARQ-ACK codebook based on the feedback window.

[0109] in,

[0110] The k1 value in the first K1 set is used to indicate the number of time units offset between the time unit where the Physical Downlink Shared Channel (PDSCH) is located and the time unit where the uplink channel corresponding to the HARQ-ACK of the PDSCH is located.

[0111] The k0 value in the K0 set is used to indicate the number of time units offset between the time unit where the Physical Downlink Shared Channel (PDSCH) is located and the time unit where the uplink control channel corresponding to the PDSCH is located.

[0112] The first scheduling method is to schedule one physical downlink shared channel (PDSCH) with one downlink control information (DCI), and the second scheduling method is to schedule multiple PDSCHs with one DCI.

[0113] In this embodiment of the disclosure, under the HARQ-ACK bundling feedback method, it is possible to ensure that regardless of any k1 value indicated by the scheduling DCI from the configured K1 set, the multiple PDSCHs scheduled by the DCI can feed back the minimum extended K1 set of the Type 1 HARQ-ACK codebook on a HARQ-ACK PUCCH resource (i.e., the extended K1 set with the fewest k1 values).

[0114] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. (Refer to...)

In one example, the second configuration information includes a Time Domain Resource Allocation (TDRA) table, the TDRA table including the K0 set under the second scheduling mode.

[0122] In one possible implementation, the method further includes: receiving third configuration information from a network device, the third configuration information including information for indicating the HARQ feedback binding value N, or determining the HARQ feedback binding value N based on a communication protocol.

[0123] In this embodiment of the disclosure, under the HARQ-ACK bundling feedback method, it is possible to ensure that regardless of any k1 value indicated by the scheduling DCI from the configured K1 set, the multiple PDSCHs scheduled by the DCI can feed back the minimum extended K1 set of the Type 1 HARQ-ACK codebook on a HARQ-ACK PUCCH resource (i.e., the extended K1 set with the fewest k1 values).

[0124] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. The method includes:

[0125] Step S31: Based on the first K1 set under the first scheduling mode, the K0 set under the second scheduling mode, and the HARQ feedback binding value N, determine the second K1 set under the second scheduling mode;

[0126] Step S32: Determine the HARQ-ACK codebook based on the second K1 set.

[0127] Wherein, the k1 value in the first K1 set is used to indicate the number of time units offset between the time unit where the physical downlink shared channel PDSCH is located and the time unit where the uplink channel corresponding to the HARQ-ACK of the PDSCH is located.

[0128] The k0 value in the K0 set is used to indicate the number of time units offset between the time unit where the Physical Downlink Shared Channel (PDSCH) is located and the time unit where the uplink control channel corresponding to the PDSCH is located. The K0 set includes at least one K0 subset, and each K0 subset includes more than one k0 value. Each k0 value corresponds to the time interval between the time units where multiple PDSCHs are located and the time unit where the DCI is located in multiple PDSCHs scheduled by a DCI under the second scheduling mode.

[0129] The first scheduling method is to schedule one physical downlink shared channel (PDSCH) with one downlink control information (DCI), and the second scheduling method is to schedule multiple PDSCHs with one DCI.

[0130] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. (Refer to...) Figure 4 , Figure 4 This is a flowchart illustrating a method for determining a HARQ-ACK codebook according to an exemplary embodiment, such as... Figure 4 As shown, this method includes:

[0131] Step S30: Receive the Time Domain Resource Allocation (TDRA) table from the network device.

[0132] Step S31: Based on the first K1 set under the first scheduling mode, the K0 set under the second scheduling mode, and the HARQ feedback binding value N, determine the second K1 set under the second scheduling mode;

[0133] Step S32: Determine the HARQ-ACK codebook based on the second K1 set.

[0134] Wherein, the k1 value in the first K1 set is used to indicate the number of time units offset between the time unit where the physical downlink shared channel PDSCH is located and the time unit where the uplink channel corresponding to the HARQ-ACK of the PDSCH is located.

[0135] The k0 value in the K0 set is used to indicate the number of time units offset between the time unit where the Physical Downlink Shared Channel (PDSCH) is located and the time unit where the uplink control channel corresponding to the PDSCH is located; the K0 set includes at least one K0 subset, which is the set of k0 values ​​contained in the r-th element of the TDRA table that contains multiple k0 values.

[0136] The first scheduling method is to schedule one physical downlink shared channel (PDSCH) with one downlink control information (DCI), and the second scheduling method is to schedule multiple PDSCHs with one DCI.

[0137] In one possible implementation, the TDRA table is shown in Table 1:

[0138] Table 1 TDRA Table

[0139]

[0140]

[0141] Here, DMRS stands for Demodulation Reference Signal.

[0142] In this TDRA table, each row corresponds to a time-domain resource scheduling mode. The time-domain resource scheduling modes identified by row indices 2 and 3 each correspond to multiple k0s. Therefore, row indices 2 and 3 correspond to (0,1,1,2) and (1,2,3,4,5,6,7,8) respectively. In this case, the set of K0s under the second scheduling mode includes (0,1,1,2) and (1,2,3,4,5,6,7,8).

[0143] It is understood that each element in Table 1 exists independently. These elements are listed in the same table as an example, but this does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values ​​of any other element in Table 1. Therefore, those skilled in the art will understand that the value of each element in Table 1 is an independent embodiment.

[0144] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. The method includes:

[0145] Step S30: Receive the Time Domain Resource Allocation (TDRA) table from the network device.

[0146] Step S31a, determine the second K1 set based on the following formula (1):

[0147]

[0148] {K1'} is the second K1 set, {K1} is the first K1 set, and k1 i It is the i-th k1 value contained in the first K1 set {K1}, k0 r,m It is {S r The m-th k0 value in}, {S r} is {P r A subset of}, {P r} is the set of k0 values ​​contained in the r-th element of the TDRA table, which contains multiple k0 values. r For {S rThe number of k0 values ​​contained in}, T r The value is M r The minimum value among N and M r It is {P r The number of k0 values ​​contained in}, min{S r} is {S r Let ∪ denote the smallest k0 value in}, where ∪ represents the union of sets.

[0149] Step S32: Determine the HARQ-ACK codebook based on the second K1 set.

[0150] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. The method includes:

[0151] Step S30: Receive the Time Domain Resource Allocation (TDRA) table from the network device.

[0152] Step S31b: Determine that the third K1 set is the first K1 set, the value of i is 0, the value of r is 0, and the value of m is 0. Execute an incrementing loop based on i, r, and m. After the loop termination condition is met, use the third K1 set as the second K1 set.

[0153] The execution content in the incremental loop based on i, r, and m includes: determining the union of the third K1 set and the combined value, and determining the union as the third K1 set;

[0154] Wherein, the combined value is k1 i +k0 r,m -min{S r};{S r} is {P r A subset of}, {P r} is the set of k0 values ​​contained in the r-th element of the TDRA table, which contains multiple k0 values. r For {S r The number of k0 values ​​contained in}, T r The value is M r The minimum value among N and M r It is {P r The number of k0 values ​​included; min{S r} is {S r The smallest k0 value in};

[0155] The loop terminates when the value of i is L-1, the value of r is R-1, and the value of m is T. r -1; The loop termination condition is that the value of i reaches L-1, the value of r reaches R-1, and the value of m reaches T. rL is the number of k1 values ​​included in the first K1 set, and R is the number of elements in the TDRA table that contain multiple k0 values.

[0156] Step S32: Determine the HARQ-ACK codebook based on the second K1 set.

[0157] In one possible implementation, step S31b corresponds to the following execution code:

[0158]

[0159] The following two examples will illustrate this in detail.

[0160] Example 1:

[0161] The number of HARQ-ACK bundles, N, is 2.

[0162] K1 set={1,2,3},.

[0163] The TDRA table contains a total of 2 TDRA elements with multiple k0 values. The first TDRA element contains 4 k0 values, corresponding to the set P. 1＝ {0,1,2,3}, the second TDRA element contains 8 k0 values, corresponding to the set P. 2＝ {1,2,3,4,5,6,7,8}.

[0164] Based on the above premises, we can determine that L = 3, R = 2, M1 = 4, M2 = 8, and N = 2.

[0165] First, a subset selection is performed for TDRA elements that contain multiple k0 values.

[0166] For the first TDRA element, its corresponding set P1 contains 4 K0 values, which is greater than N (i.e., greater than 2). Therefore, the two largest K0 values ​​are selected from P1 to determine the new set S. 1＝ {2,3}. The minimum value in S1 is 2, min(S r =2.

[0167] For the second TDRA element, its corresponding set P1 contains 8 K0 values, which is greater than N (i.e., greater than 2). Therefore, the two largest K0 values ​​are selected from P2 to determine the new set S. 2＝ {7,8}. The minimum value in S2 is 7, min(S r =7.

[0168] Set {K1'} = {K1}, that is, {K1'} = {1,2,3}

[0169] When i = 0 and r = 0:

[0170] When m = 0, k1 i +k0 r,m -min(S r The value of ) is 1+2-2, which is 1. The union of {K1'} and this value is {1,2,3}. Therefore, {K1'} is updated to {1,2,3}.

[0171] When m=1, k1 i +k0 r,m -min(S r The value of ) is 1+3-2, which is 2. The union of {K1'} and this value is {1,2,3}. Therefore, {K1'} is updated to {1,2,3}.

[0172] When i = 0 and r = 1:

[0173] When m = 0, k1 i +k0 r,m -min(S r The value of ) is 1+7-7, which is 1. The union of {K1'} and this value is {1,2,3}. Update {K1'} to {1,2,3}.

[0174] When m=1, k1 i +k0 r,m -min(S r The value of ) is 1+8-7, which is 2. The union of {K1'} and this value is {1,2,3}. Therefore, {K1'} is updated to {1,2,3}.

[0175] When i = 1 and r = 0:

[0176] When m = 0, k1 i +k0 r,m -min(S r The value of ) is 2+2-2, which is 2. The union of {K1'} and this value is {1,2,3}. Therefore, {K1'} is updated to {1,2,3}.

[0177] When m=1, k1 i +k0 r,m -min(S r The value of ) is 2+3-2, which is 3. The union of {K1'} and this value is {1,2,3}. Therefore, {K1'} is updated to {1,2,3}.

[0178] When i = 1 and r = 1:

[0179] When m = 0, k1 i +k0 r,m -min(S r The value of ) is 2+7-7, which is 2. The union of {K1'} and this value is {1,2,3}. Therefore, {K1'} is updated to {1,2,3}.

[0180] When m=1, k1 i +k0 r,m -min(S r The value of ) is 2+8-7, which is 3. The union of {K1'} and this value is {1,2,3}. Therefore, {K1'} is updated to {1,2,3}.

[0181] When i = 2 and r = 0:

[0182] When m = 0, k1 i +k0 r,m -min(S r The value of ) is 3+2-2, which is 3. The union of {K1'} and this value is {1,2,3}. Therefore, {K1'} is updated to {1,2,3}.

[0183] When m=1, k1 i +k0 r,m -min(S r The value of ) is 3+3-2, which is 4. The union of {K1'} and this value is {1,2,3,4}. Therefore, {K1'} is updated to {1,2,3,4}.

[0184] When i = 2 and r = 1:

[0185] When m = 0, k1 i +k0 r,m -min(S r The value of ) is 3+7-7, which is 3. The union of {K1'} and this value is {1,2,3,4}. Update {K1'} to {1,2,3,4}.

[0186] When m=1, k1 i +k0 r,m -min(S r The value of ) is 3+8-7, which is 4. The union of {K1'} and this value is {1,2,3,4}. Therefore, {K1'} is updated to {1,2,3,4}.

[0187] Therefore, {K1'} is finally determined to be {1,2,3,4}.

[0188] Example 2:

[0189] The number of HARQ-ACK bundles, N, is 4.

[0190] K1 set={1,2,3},.

[0191] The TDRA table contains a total of 2 TDRA elements with multiple k0 values. The first TDRA element contains 3 k0 values, corresponding to the set P. 1＝ {0,1,2}, the second TDRA element contains 8 k0 values, corresponding to the set P. 2＝ {1,2,3,4,5,6,7,8}.

[0192] Based on the above premises, we can determine that L = 3, R = 2, M1 = 4, M2 = 8, and N = 4.

[0193] First, a subset selection is performed for TDRA elements that contain multiple k0 values.

[0194] For the first TDRA element, the set P1 contains 3 K0 values, which is less than N (i.e., less than 4). Therefore, P1 is determined as the new set S. 1＝ {0,1,2}. The minimum value in S1 is 0, min(S r ) = 0.

[0195] For the second TDRA element, its corresponding set P1 contains 8 K0 values, which is greater than N (i.e., greater than 4). Select the 4 largest K0 values ​​from P2 to determine the new set S. 2＝ {5,6,7,8}. The minimum value in S2 is 5, min(S r =5.

[0224] Therefore, {K1'} is finally determined to be {1,2,3,4,5,6}.

[0225] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. The method includes:

[0226] Step S30: Receive the Time Domain Resource Allocation (TDRA) table from the network device.

[0228] The fourth K1 set is determined based on the fourth K1 set, which is initially set to be empty, and the following two formulas:

[0229]

[0230] {K1”}={K1}∪{K1'} (3)

[0231] {K1”} is the second K1 set, {K1'} is the fourth K1 set, {K1} is the first K1 set, and k1 i It is the i-th k1 value contained in the first K1 set {K1}, k0 r,m It is {S r The m-th k0 value in}, {S r} is {P r A subset of}, {P r} is the set of k0 values ​​contained in the r-th element of the TDRA table, which contains multiple k0 values. r For {S r The number of k0 values ​​contained in}, T r The value is M r The minimum value among N and M r It is {P r The number of k0 values ​​contained in}, min{S r} is {S r Let ∪ denote the smallest k0 value in}, where ∪ represents the union of sets.

[0232] Step S32: Determine the HARQ-ACK codebook based on the second K1 set.

[0233] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. The method includes:

[0234] Step S30: Receive the Time Domain Resource Allocation (TDRA) table from the network device.

[0235] Step S31d-1: Based on the first K1 set under the first scheduling mode, the K0 set under the second scheduling mode, and the HARQ feedback binding value N, determine the fourth K1 set under the second scheduling mode;

[0236] Determine that the fourth K1 set is an empty set, the value of i is 0, the value of r is 0, and the value of m is 0, and execute an incrementing loop based on i, r, and m until the loop termination condition is met;

[0237] The execution content in the incremental loop based on i, r, and m includes: determining the union of the fourth K1 set and the combined value, and determining the union as the fourth K1 set;

[0238] Wherein, the combined value is k1 i +k0 r,m -min{S r};{S r} is {P r A subset of}, {P r} is the set of k0 values ​​contained in the r-th element of the TDRA table, which contains multiple k0 values. r For {S r The number of k0 values ​​contained in}, T r The value is less than or equal to N; min{S r} is {S r The smallest k0 value in};

[0239] The loop terminates when the value of i is L-1, the value of r is R-1, and the value of m is T. r -1; The loop termination condition is that the value of i reaches L-1, the value of r reaches R-1, and the value of m reaches T. r L is the number of k1 values ​​included in the first K1 set, and R is the number of elements in the TDRA table that contain multiple k0 values.

[0240] Step S31d-2: Determine that the union of the fourth K1 set and the first K1 set is the second K1 set.

[0241] Step S32: Determine the HARQ-ACK codebook based on the second K1 set.

[0242] In one possible implementation, step S31b corresponds to the following execution code:

[0243]

[0244] In this embodiment of the present disclosure, setting the fourth K1 set to an empty set in step S31d-1 reduces the number of merge operations compared to setting the fourth K1 set to {K1}, thereby improving processing efficiency.

[0245] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. The method includes:

[0246] Step S30: Receive the Time Domain Resource Allocation (TDRA) table from the network device.

[0247] Steps S31a, S31b, S31c, or S31d1-2.

[0248] Wherein, if the {P r} contains more than N k0 values, from {P r Select N k0 values ​​as {S} r};

[0249] If the {P r If the number of K0s contained in {P} is less than or equal to N, then {P} r} as {S r}

[0251] First, from {P r Select the N largest k0 values ​​from the list;

[0252] Second, select the k0 values ​​corresponding to the last N PDSCHs in the time position among multiple PDSCHs scheduled in the same DCI;

[0253] Third, select the k0 value corresponding to the last PDSCH in the time position of multiple PDSCHs in the same DCI scheduling, as well as any other N-1 k0 values.

[0254] Step S32: Determine the HARQ-ACK codebook based on the second K1 set.

[0255] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. (Refer to...) Figure 5 , Figure 5 This is a flowchart illustrating a method for determining a HARQ-ACK codebook according to an exemplary embodiment, such as... Figure 5 As shown, this method includes:

[0256] Step S31: Based on the first K1 set under the first scheduling mode, the K0 set under the second scheduling mode, and the HARQ feedback binding value N, determine the second K1 set under the second scheduling mode;

[0257] Step S32: Determine the HARQ-ACK codebook based on the second K1 set.

[0258] Step S33: Determine the feedback window of the HARQ-ACK codebook based on the second K1 set; feed back the HARQ-ACK codebook based on the feedback window.

[0259] Wherein, the k1 value in the first K1 set is used to indicate the number of time units offset between the time unit where the physical downlink shared channel PDSCH is located and the time unit where the uplink channel of the HARQ-ACK corresponding to the PDSCH is located; the k0 value in the K0 set is used to indicate the number of time units offset between the time unit where the physical downlink shared channel PDSCH is located and the time unit where the uplink control channel corresponding to the PDSCH is located.

[0260] The first scheduling method is to schedule one physical downlink shared channel (PDSCH) with one downlink control information (DCI), and the second scheduling method is to schedule multiple PDSCHs with one DCI.

[0261] In this embodiment of the disclosure, under the HARQ-ACK bundling feedback method, it is possible to ensure that regardless of any k1 value indicated by the scheduling DCI from the configured K1 set, the multiple PDSCHs scheduled by the DCI can feed back the minimum extended K1 set of the Type 1 HARQ-ACK codebook on a HARQ-ACK PUCCH resource (i.e., the extended K1 set with the fewest k1 values).

[0262] This disclosure provides a method for determining a HARQ-ACK codebook, which is executed by user equipment 101. (Refer to...) Figure 6 , Figure 6 This is a flowchart illustrating a method for determining a HARQ-ACK codebook according to an exemplary embodiment, such as... Figure 6 As shown, this method includes:

[0263] Step S30: Receive configuration information from the network device. The configuration information may include first configuration information, second configuration information, and third configuration information.

[0264] The first configuration information includes information used to indicate the first K1 set under the first scheduling mode.
