[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202311017318.6 and application date August 11, 2023, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a method, device, and storage medium for determining PUCCH power control parameters. Background Art

[0004] In NR (New Radio) Rel-17 (Release 17), HARQ-ACK (Hybrid Automatic Repeat Request-Acknowledgement) codebook retransmission and SPS (Semi-Persistent Scheduling) delay are supported, but in both cases, codebook concatenation occurs. For example, when SPS delay is supported, if a HARQ-ACK codebook exists in the target time slot, the delayed SPS HARQ-ACK codebook is concatenated after the HARQ-ACK codebook in the target time slot, resulting in two codebooks concatenated in the target time slot: the initial codebook (the HARQ-ACK codebook in the target time slot) + the SPS delayed codebook. For another example, when HARQ-ACK codebook retransmission is supported, if a HARQ-ACK codebook exists in the target retransmission time slot, the HARQ-ACK retransmission codebook is concatenated after the HARQ-ACK codebook in the target retransmission time slot, thereby concatenating two codebooks in the target time slot: the initial codebook (the HARQ-ACK codebook in the target retransmission time slot) + the HARQ-ACK retransmission codebook.

[0005] In the related art, it is unclear how to determine the power of the PUCCH (Physical Uplink Control Channel) in the case of codebook concatenation. Therefore, it is necessary to study how to determine the power of the PUCCH in the case of codebook concatenation.

[0033] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0034] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] In the related art, NR Rel-17 supports SPS HARQ-ACK delay, and determines the initial time slot for SPS HARQ-ACK feedback based on K1. In the initial time slot of SPS HARQ-ACK, the UCI (Uplink Control Information) multiplexing process of Rel-16 is first performed. If the SPS HARQ-ACK after multiplexing is transmitted using the resources configured by SPS-PUCCH-AN-List-r16 or n1PUCCH-AN, and this resource is invalid, the SPS HARQ-ACK configured with SPS HARQ-ACK delay is delayed. Based on the conditions for delaying from the initial time slot, it is determined in sequence whether the next time slot / sub-time slot is the target time slot until the target time slot is found. The delayed SPS HARQ-ACK feedback bit is appended to the initial HARQ-ACK bit in the target time slot. This method is applicable to Type-1 codebook and Type-2 codebook.

[0037] NR Rel-17 also supports HARQ-ACK codebook retransmission, that is, triggering the retransmission of discarded HARQ-ACK on PUCCH resources through DCI (Downlink Control Information). Considering that there may be an initial Type-1 or Type-2 codebook in the target retransmission time slot where the HARQ-ACK retransmission codebook is located, the HARQ-ACK retransmission codebook is cascaded after the initial Type-1 or Type-2 codebook of the same priority.

[0038] If there is still a delayed SPS HARQ-ACK codebook in the target retransmission time slot, the delayed SPS HARQ-ACK codebook is appended to the HARQ-ACK retransmission codebook and the initial codebook, that is, there are three codebook information cascaded in this time slot, in the order of initial / new codebook, HARQ-ACK retransmission codebook, and SPS delayed codebook.

[0039] In NR, for PUCCH power control, the power adjustment value is calculated based on the UCI parameters carried by PUCCH. Specifically, for PUCCH format 2 / 3 / 4 and when the number of UCI bits is less than or equal to 11, the power adjustment value is calculated based on n HARQ-ACK Calculate the power adjustment value. For PUCCH format 2 / 3 / 4 and when the number of UCI bits is greater than 11, based on ACK Calculate the power adjustment value. Where n HARQ-ACK is the calculated number of HARQ-ACK bits, O ACK It is the number of HARQ-ACK bits carried on the PUCCH. However, for the case of codebook cascading, it is not clear how to determine the PUCCH power.

[0040] Therefore, an embodiment of the present application provides a PUCCH power control parameter determination method, device and storage medium for determining the PUCCH power control parameters based on the configuration of the terminal device and the codebook contained in the PUCCH, wherein the PUCCH power control parameters are used to determine the power of the PUCCH, thereby solving the technical problem in the related art that it is unclear how to determine the power of the PUCCH in the case of codebook cascading.

[0046] The following describes the PUCCH power control parameter determination method, device, and storage medium according to the embodiments of the present application with reference to the accompanying drawings.

[0047] FIG1 is a schematic flow chart of a method for determining PUCCH power control parameters according to the first embodiment of the present application.

[0048] It should be noted that the PUCCH power control parameter determination method of the embodiment of the present application can be performed by the PUCCH power control parameter determination device provided in the embodiment of the present application. The PUCCH power control parameter determination device can be an electronic device, or can be configured in an electronic device.

[0049] As shown in FIG1 , the method for determining the PUCCH power control parameter may include the following steps:

[0050] Step 101: Determine a PUCCH power control parameter based on the configuration of the terminal device and a codebook included in the physical uplink control channel PUCCH, wherein the PUCCH power control parameter is used to determine the power of the PUCCH.

[0051] The configuration of the terminal device includes at least one of SPS delay and HARQ-ACK retransmission.

[0052] The codebook included in the PUCCH includes at least one of an initial transmission codebook, an SPS delay codebook, and a HARQ-ACK retransmission codebook.

[0053] In some embodiments, the PUCCH power control parameter may be determined based on the configuration of the terminal device and the codebook included in the PUCCH. For example, in the case where the terminal device is configured with SPS delay and / or HARQ-ACK retransmission, in response to the HARQ-ACK being carried in PUCCH format 2 / 3 / 4 and the number of UCI feedback bits being greater than 2 and less than or equal to 11, the PUCCH power control parameter n may be determined based on the codebook transmission of the HARQ-ACK on the PUCCH. HARQ-ACK .

[0054] The PUCCH power control parameter determination method provided in the present application determines the PUCCH power control parameter by based on the configuration of the terminal device and the codebook contained in the physical uplink control channel PUCCH, wherein the PUCCH power control parameter is used to determine the power of the PUCCH, thereby solving the technical problem in the related art of not knowing how to determine the power of the PUCCH in the case of codebook cascading.

[0055] In order to clearly illustrate how the PUCCH power control parameters are determined in this application when the configuration of the terminal device includes SPS delay, an embodiment of the present application provides a possible implementation method of the PUCCH power control parameter determination method. Figure 2 is a flow chart of the PUCCH power control parameter determination method provided according to the second embodiment of the present application.

[0056] As shown in FIG2 , the method for determining the PUCCH power control parameter may include the following steps:

[0057] Step 201: When the configuration of the terminal device includes a semi-persistent scheduling SPS delay, a PUCCH power control parameter is determined according to a first hybrid automatic repeat request-determined HARQ-ACK parameter and a second HARQ-ACK parameter.

[0058] It should be noted that when the configuration of the terminal device includes semi-persistent scheduling SPS delay, the codebook cascade situation of the codebook included in the PUCCH is that the PUCCH contains both the initial transmission codebook and the SPS delay codebook, wherein the initial transmission codebook is the initial codebook, which refers to the initial HARQ-ACK bit in the target time slot.

[0059] The inclusion of both the initial transmission codebook and the SPS delayed codebook in the PUCCH means that there is an initial HARQ-ACK bit in the target time slot, and the delayed SPS HARQ-ACK feedback bit needs to be appended after the initial HARQ-ACK bit in the target time slot.

[0060] In addition to the above codebook concatenation, the codebook transmission of HARQ-ACK on PUCCH may also have the following two situations:

[0061] Case 1: The PUCCH contains only the SPS delayed codebook, that is, there is no initial HARQ-ACK bit in the target time slot, and only the delayed SPS HARQ-ACK feedback bit needs to be transmitted in the target time slot;

[0062] Case 2: The PUCCH contains only the initial transmission codebook, that is, only the initial HARQ-ACK bits exist in the target time slot, and there is no delayed SPS HARQ-ACK feedback bit.

[0063] In which, when the PUCCH includes the initial transmission codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, and when the PUCCH does not include the initial transmission codebook, the first HARQ-ACK parameter is a first fixed value.

[0064] The first fixed value can be selected based on actual needs in the embodiment of the present application. Optionally, the first fixed value can be set based on manual experience, for example, the first fixed value can be set to 0, or the first fixed value can be dynamically adjusted based on actual application requirements. In the embodiment of the present application, the selection can be based on actual needs.

[0065] In which, when the SPS delay codebook is included in the PUCCH, the second HARQ-ACK parameter is determined based on the number of bits of the SPS delay codebook, and when the SPS delay codebook is not included in the PUCCH, the second HARQ-ACK parameter is a second fixed value. Optionally, if the SPS delay codebook is included in the PUCCH, the second HARQ-ACK parameter may be equal to the number of bits of the SPS delay codebook.

[0066] Similarly, the value of the second fixed value can be selected according to actual needs in the embodiment of the present application. Optionally, the second fixed value can be set based on manual experience, for example, the second fixed value can be set to 0, or the second fixed value can be dynamically adjusted according to actual application requirements. In the embodiment of the present application, the selection can be made according to actual needs.

[0067] In some embodiments, when the configuration of the terminal device includes SPS delay, the sum of the first HARQ-ACK parameter and the second HARQ-ACK parameter can be determined as the PUCCH power control parameter. Thus, through the description of the values ​​of the first HARQ-ACK parameter and the second HARQ-ACK parameter, it can be seen that for the above-mentioned codebook cascade, since PUCCH contains both the initial transmission codebook and the SPS delay codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, and the second HARQ-ACK parameter is determined based on the number of bits of the SPS delay codebook. At this time, the PUCCH power control parameter is the sum of the first HARQ-ACK parameter and the second HARQ-ACK parameter; for the above-mentioned case one, since PUCCH only contains SP S delayed codebook, the first HARQ-ACK parameter is a first fixed value, and the second HARQ-ACK parameter is determined based on the number of bits of the SPS delayed codebook. At this time, the PUCCH power control parameter is the sum of the first fixed value and the second HARQ-ACK parameter; for the above situation 2, since the PUCCH only contains the initial transmission codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, and the second HARQ-ACK parameter is a second fixed value. At this time, the PUCCH power control parameter is the sum of the first HARQ-ACK parameter and the second fixed value.

[0068] As an example, it is assumed that the first HARQ-ACK parameter is represented by nHARQ-ACK,0 and the second HARQ-ACK parameter is represented by 0 SPS Indicates that the PUCCH power control parameter is expressed as n HARQ-ACK Indicates that nHARQ-ACK, 0+0 SPS As n HARQ-ACK Determine the power of PUCCH. If the PUCCH contains the initial transmission codebook, nHARQ-ACK,0 is determined based on the initial transmission codebook, otherwise nHARQ-ACK,0 is equal to 0; if the PUCCH contains the SPS delay codebook, 0 SPS Equal to the number of bits in the SPS delay codebook, otherwise O SPS Equal to 0.

[0069] The PUCCH power control parameter determination method provided in the present application determines the PUCCH power control parameter by determining the HARQ-ACK parameter and the second HARQ-ACK parameter according to the first hybrid automatic repeat request when the configuration of the terminal device includes semi-persistent scheduling SPS delay, thereby solving the technical problem in the related art of not knowing how to determine the PUCCH power in the case of codebook cascading.

[0070] The previous embodiment describes a possible implementation method for determining PUCCH power control parameters when the configuration of the terminal device includes SPS delay. The embodiment of the present application provides another possible implementation method for determining PUCCH power control parameters when the configuration of the terminal device includes SPS delay. Figure 3 is a flow chart of the PUCCH power control parameter determination method provided according to the third embodiment of the present application.

[0071] As shown in FIG3 , the method for determining the PUCCH power control parameter may include the following steps 301 and 302 .

[0072] Step 301: When the configuration of the terminal device includes SPS delay and the PUCCH only includes an SPS delay codebook, determine a PUCCH power control parameter based on the number of bits of the SPS delay codebook.

[0073] In some embodiments, when the configuration of the terminal device includes SPS delay and the PUCCH only contains the SPS delay codebook, the number of bits of the SPS delay codebook can be determined as the PUCCH power control parameter, that is, the PUCCH power control parameter is equal to the number of bits of the SPS delay codebook.

[0074] It should be noted that, for the embodiment shown in Figure 2, when the configuration of the terminal device includes SPS delay and the PUCCH only contains the SPS delay codebook, the first HARQ-ACK parameter is a first fixed value, so that the PUCCH power control parameter is the sum of the first fixed value and the second HARQ-ACK parameter, wherein the second HARQ-ACK parameter is determined based on the number of bits of the SPS delay codebook. At this time, if the first fixed value is 0, the PUCCH power control parameter is equal to 0 + the second HARQ-ACK parameter, that is, the PUCCH power control parameter is equal to the second HARQ-ACK parameter, that is, the PUCCH power control parameter is determined based on the number of bits of the SPS delay codebook, which is consistent with the scheme provided in this step; if the first fixed value is not 0, the PUCCH power control parameter is the sum of the first fixed value (non-zero value) and the second HARQ-ACK parameter, which is different from the scheme provided in this step.

[0075] Step 302: When the configuration of the terminal device includes SPS delay and the PUCCH includes an SPS delay codebook and an initial transmission codebook, determine a PUCCH power control parameter based on the initial transmission codebook.

[0076] In some embodiments, when the configuration of the terminal device includes SPS delay and the PUCCH includes an SPS delay codebook and an initial transmission codebook, the PUCCH power control parameters can be determined directly based on the initial transmission codebook without considering the SPS delay codebook.

[0077] It should be noted that in an embodiment of the present application, when the configuration of the terminal device includes SPS delay and the PUCCH contains an SPS delay codebook and an initial transmission codebook, in addition to being able to directly determine the PUCCH power control parameter based on the initial transmission codebook without considering the SPS delay codebook, the scheme provided by the embodiment shown in Figure 2 can be continued, that is, the first HARQ-ACK parameter is determined based on the initial transmission codebook, the second HARQ-ACK parameter is determined based on the number of bits of the SPS delay codebook, and then the PUCCH power control parameter is determined based on the first HARQ-ACK parameter and the second HARQ-ACK parameter.

[0078] As an example, it is assumed that the first HARQ-ACK parameter is represented by nHARQ-ACK,0 and the second HARQ-ACK parameter is represented by 0 SPS Indicates that the PUCCH power control parameter is expressed as n HARQ-ACK Indicates that n can be determined based on the codebook included in the PUCCH HARQ-ACK Specifically, if the PUCCH only contains the SPS delay codebook, then 0 SPS As n HARQ-ACK Determine the power of PUCCH, where O SPS Equal to the number of bits in the SPS delay codebook; if the PUCCH contains both the SPS delay codebook and the initial transmission codebook, n can be determined according to the initial transmission codebook HARQ-ACK , without considering the SPS delay codebook, or, nHARQ-ACK can be determined according to the initial transmission codebook, 0, O SPS Equal to the number of bits in the SPS delay codebook, nHARQ-ACK, 0+0 SPS As n HARQ-ACK Determine the power of PUCCH.

[0079] The present application provides a method for determining PUCCH power control parameters, which solves the technical problem in the related art of not knowing how to determine the PUCCH power in the case of codebook cascading by determining the PUCCH power control parameters based on the number of bits of the SPS delay codebook when the configuration of the terminal device includes SPS delay and the PUCCH only includes an SPS delay codebook, or by determining the PUCCH power control parameters based on the initial transmission codebook when the configuration of the terminal device includes SPS delay and the PUCCH includes an SPS delay codebook and an initial transmission codebook.

[0080] In order to clearly illustrate how to determine the PUCCH power control parameters when the configuration of the terminal device includes SPS delay, an example is given below to illustrate.

[0081] As an example, for the case where SPS HARQ-ACK delay is configured, when HARQ-ACK is carried on PUCCH format 2 / 3 / 4 and the number of UCI feedback bits is greater than 2 and less than or equal to 11, the PUCCH power control parameter n can be determined based on the codebook transmission of HARQ-ACK on PUCCH. HARQ-ACK , thereby determining the power of PUCCH. HARQ-ACK The determination method is as follows:

[0082] Solution 1: nHARQ-ACK, 0+0 SPS As n HARQ-ACK Determine the power of PUCCH.

[0083] If the PUCCH contains the initial transmission codebook, nHARQ-ACK,0 is determined based on the initial transmission codebook; otherwise, nHARQ-ACK,0 is equal to 0.

[0084] If the PUCCH contains the SPS delay codebook, SPS Equal to the number of bits in the SPS delay codebook, otherwise O SPS Equal to 0.

[0085] Solution 2: Determine n based on the codebook contained in the PUCCH HARQ-ACK , thereby determining the power of PUCCH. Specifically:

[0086] If the PUCCH only contains the SPS delay codebook, then n HARQ-ACK Equal to the number of bits in the SPS delay codebook;

[0087] If the PUCCH contains both the SPS delayed codebook and the initial transmission codebook, then:

[0088] Solution 2-1: Determine n according to the initial codebook HARQ-ACK , without considering the SPS delay codebook.

[0089] Solution 2-2: Determine nHARQ-ACK according to the initial codebook, 0, 0 SPS Equal to the number of bits in the SPS delay codebook, nHARQ-ACK, 0+0 SPS As n HARQ-ACK Determine the power of PUCCH.

[0090] Therefore, assuming that the UE is configured with SPS HARQ-ACK delay and uses PUCCH format 2 / 3 / 4 to carry HARQ-ACK for transmission, when the PUCCH carries 0 ACK +O SR +O CSIWhen ≤11, the UE can determine the number of HARQ-ACK information bits used for PUCCH transmission power determination based on the above two schemes, that is, the PUCCH power control parameter n HARQ-ACK , when PUCCH carries O ACK +O SR +O CSI When >11, the UE may determine the number of HARQ-ACK information bits used for PUCCH transmission power determination based on the total number of bits in the cascaded HARQ-ACK codebook. ACK .

[0091] It should be noted that in the above scheme, nHARQ-ACK is determined based on the initial transmission codebook, 0 or n HARQ-ACK If the initial codebook is Type-1 HARQ-ACK codebook, then nHARQ-ACK described here is 0 or n HARQ-ACK As defined in 3GPP TS 38.213 Section 9.1.2.1 or 16.5.1.1 HARQ-ACK ; If the initial codebook is Type-2 HARQ-ACK codebook, then nHARQ-ACK described here is 0 or n HARQ-ACK As defined in 3GPP TS38.213 Section 9.1.3.1 or 9.1.3.3 or 16.5.2.1 HARQ-ACK .

[0092] In summary, for the case where SPS HARQ-ACK delay is configured, when HARQ-ACK is carried on PUCCH format 2 / 3 / 4 and the number of UCI feedback bits is greater than 2 and less than or equal to 11, the PUCCH power control parameter n can be determined based on the codebook transmission of HARQ-ACK on PUCCH. HARQ-ACK , ensuring the PUCCH transmission performance in this case.

[0093] In order to clearly illustrate how the PUCCH power control parameters are determined in the present application when the configuration of the terminal device includes HARQ-ACK codebook retransmission, an embodiment of the present application provides a possible implementation method of a PUCCH power control parameter determination method. Figure 4 is a flow chart of the PUCCH power control parameter determination method provided according to the fourth embodiment of the present application.

[0094] As shown in FIG4 , the method for determining the PUCCH power control parameter may include the following steps:

[0095] Step 401: When the configuration of the terminal device includes HARQ-ACK retransmission, determine the PUCCH power control parameter according to the first HARQ-ACK parameter and the third HARQ-ACK parameter.

[0096] It should be noted that when the configuration of the terminal device includes HARQ-ACK retransmission, the codebook cascade situation of the codebook included in the PUCCH is that the PUCCH contains both the initial transmission codebook and the HARQ-ACK retransmission codebook, where the initial transmission codebook is the initial codebook.

[0097] The inclusion of both the initial transmission codebook and the HARQ-ACK retransmission codebook in the PUCCH means that an initial Type-1 or Type-2 codebook may exist in the target retransmission time slot where the HARQ-ACK retransmission codebook is located, and the HARQ-ACK retransmission codebook is cascaded after the initial Type-1 or Type-2 codebook of the same priority.

[0098] In addition to the above codebook concatenation, the codebook transmission of HARQ-ACK on PUCCH may also have the following two situations:

[0099] Case 1: The PUCCH contains only the HARQ-ACK retransmission codebook. That is, the target retransmission time slot where the HARQ-ACK retransmission codebook is located does not contain the initial Type-1 or Type-2 codebook. Therefore, it is sufficient to transmit the HARQ-ACK retransmission codebook in the target retransmission time slot.

[0100] Case 2: The PUCCH contains only the initial transmission codebook, that is, only the initial Type-1 or Type-2 codebook exists in the target retransmission time slot, and there is no HARQ-ACK retransmission codebook.

[0101] Among them, when the PUCCH includes the initial transmission codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, and when the PUCCH does not include the initial transmission codebook, the first HARQ-ACK parameter is a third fixed value.

[0102] The first fixed value can be selected based on actual needs in the embodiment of the present application. Optionally, the first fixed value can be set based on manual experience, for example, the first fixed value can be set to 0, or the first fixed value can be dynamically adjusted based on actual application requirements. In the embodiment of the present application, the selection can be based on actual needs.

[0103] In which, when the PUCCH includes a HARQ-ACK retransmission codebook, the third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook, and when the PUCCH does not include a HARQ-ACK retransmission codebook, the third HARQ-ACK parameter is a third fixed value. Optionally, if the PUCCH includes a HARQ-ACK retransmission codebook, the third HARQ-ACK parameter may be determined based on the HARQ-ACK retransmission codebook, or the third HARQ-ACK parameter may be equal to the number of bits of the HARQ-ACK retransmission codebook.

[0104] Similarly, the value of the third fixed value can be selected according to actual needs in the embodiment of the present application. Optionally, the third fixed value can be set based on manual experience, for example, the third fixed value can be set to 0, or the third fixed value can be dynamically adjusted according to actual application requirements. In the embodiment of the present application, the selection can be made according to actual needs.

[0105] In some embodiments, when the configuration of the terminal device includes a HARQ-ACK retransmission codebook, the sum of the first HARQ-ACK parameter and the third HARQ-ACK parameter can be determined as the PUCCH power control parameter. Thus, through the description of the values ​​of the first HARQ-ACK parameter and the third HARQ-ACK parameter, it can be seen that for the above-mentioned codebook cascade, since the PUCCH contains both the initial transmission codebook and the HARQ-ACK retransmission codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, and the third HARQ-ACK parameter is determined based on the number of bits of the HARQ-ACK retransmission codebook. At this time, the PUCCH power control parameter is the sum of the first HARQ-ACK parameter and the third HARQ-ACK parameter; for the above-mentioned case one, since the PUCCH only contains the HARQ-ACK retransmission codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, and the third HARQ-ACK parameter is determined based on the number of bits of the HARQ-ACK retransmission codebook. If the initial transmission codebook is not included in the PUCCH, the first HARQ-ACK parameter is a first fixed value, and the third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits in the HARQ-ACK retransmission codebook. At this time, the PUCCH power control parameter is the sum of the first fixed value and the third HARQ-ACK parameter. For the above situation 2, since the PUCCH only contains the initial transmission codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, and the third HARQ-ACK parameter is a third fixed value. At this time, the PUCCH power control parameter is the sum of the first HARQ-ACK parameter and the third fixed value.

[0106] As an example, it is assumed that the first HARQ-ACK parameter is represented by nHARQ-ACK, 0, and the third HARQ-ACK parameter is represented by nHARQ-ACK, 1 or 0. retranIndicates that the PUCCH power control parameter is expressed as n HARQ-ACK Indicates that nHARQ-ACK, 0+nHARQ-ACK, 1 or nHARQ-ACK, 0+0 can be used. retran As n HARQ-ACK Determine the power of PUCCH. If the PUCCH contains the initial transmission codebook, nHARQ-ACK,0 is determined based on the initial transmission codebook, otherwise nHARQ-ACK,0 is equal to 0; if the PUCCH contains the HARQ-ACK retransmission codebook, nHARQ-ACK,1 is determined based on the HARQ-ACK retransmission codebook or 0 retran Equal to the number of bits in the HARQ-ACK retransmission codebook, otherwise nHARQ-ACK, 1 or 0 retran Equal to 0.

[0107] The PUCCH power control parameter determination method provided in the present application determines the PUCCH power control parameter according to the first HARQ-ACK parameter and the third HARQ-ACK parameter when the configuration of the terminal device includes HARQ-ACK retransmission, thereby solving the technical problem in the related art of not knowing how to determine the PUCCH power in the case of codebook cascading.

[0108] The previous embodiment describes a possible implementation method for determining PUCCH power control parameters when the configuration of the terminal device includes HARQ-ACK retransmission. The embodiment of the present application provides another possible implementation method for determining PUCCH power control parameters when the configuration of the terminal device includes HARQ-ACK retransmission. Figure 5 is a flow chart of the PUCCH power control parameter determination method provided according to the fifth embodiment of the present application.

[0109] As shown in FIG5 , the method for determining the PUCCH power control parameter may include the following steps 501 and 502 .

[0110] Step 501: When the configuration of the terminal device includes HARQ-ACK retransmission and the PUCCH only contains the HARQ-ACK retransmission codebook, determine the PUCCH power control parameter based on the HARQ-ACK retransmission codebook or the number of bits in the HARQ-ACK retransmission codebook.

[0111] In some embodiments, when the configuration of the terminal device includes HARQ-ACK retransmission and the PUCCH only contains a HARQ-ACK retransmission codebook, the PUCCH power control parameter can be determined based on the HARQ-ACK retransmission codebook, or the number of bits of the HARQ-ACK retransmission codebook can be determined as the PUCCH power control parameter, that is, the PUCCH power control parameter is equal to the number of bits of the HARQ-ACK retransmission codebook.

[0112] It should be noted that, for the embodiment shown in Figure 4, when the configuration of the terminal device includes HARQ-ACK retransmission and the PUCCH only contains a HARQ-ACK retransmission codebook, since the first HARQ-ACK parameter is a first fixed value, the PUCCH power control parameter is the sum of the first fixed value and the third HARQ-ACK parameter, wherein the third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook. At this time, if the first fixed value is 0, the PUCCH power control parameter is equal to 0+the third HARQ-ACK parameter, that is, the PUCCH power control parameter is equal to the third HARQ-ACK parameter, that is, the PUCCH power control parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook, which is consistent with the scheme provided in this step; if the first fixed value is not 0, the PUCCH power control parameter is the sum of the first fixed value (non-zero value) and the third HARQ-ACK parameter, which is different from the scheme provided in this step.

[0113] Step 502: When the configuration of the terminal device includes HARQ-ACK retransmission and the PUCCH includes a HARQ-ACK retransmission codebook and an initial transmission codebook, determine a PUCCH power control parameter based on the initial transmission codebook.

[0114] In some embodiments, when the configuration of the terminal device includes HARQ-ACK retransmission and the PUCCH contains a HARQ-ACK retransmission codebook and an initial transmission codebook, the PUCCH power control parameters can be determined directly based on the initial transmission codebook without considering the HARQ-ACK retransmission codebook.

[0115] It should be noted that in an embodiment of the present application, when the configuration of the terminal device includes HARQ-ACK retransmission and the PUCCH contains a HARQ-ACK retransmission codebook and an initial transmission codebook, in addition to directly determining the PUCCH power control parameter based on the initial transmission codebook without considering the HARQ-ACK retransmission codebook, the scheme provided by the embodiment shown in Figure 4 can be continued, that is, the first HARQ-ACK parameter is determined based on the initial transmission codebook, the third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook, and then the PUCCH power control parameter is determined based on the first HARQ-ACK parameter and the third HARQ-ACK parameter.

[0116] As an example, it is assumed that the first HARQ-ACK parameter is represented by nHARQ-ACK, 0, and the third HARQ-ACK parameter is represented by nHARQ-ACK, 1 or 0. retran Indicates that the PUCCH power control parameter is expressed as n HARQ-ACKIndicates that n can be determined based on the codebook included in the PUCCH HARQ-ACK Specifically, if the PUCCH only contains the HARQ-ACK retransmission codebook, nHARQ-ACK can be set to 1 or 0. retran As n HARQ-ACK Determine the power of PUCCH, where 0 SPS As n HARQ-ACK Determine the power of PUCCH, where O SPS Equal to the number of bits in the SPS delay codebook; if the PUCCH contains both the HARQ-ACK retransmission codebook and the initial transmission codebook, n can be determined according to the initial transmission codebook HARQ-ACK , regardless of the HARQ-ACK retransmission codebook, or nHARQ-ACK can be determined according to the initial transmission codebook, 0, and nHARQ-ACK can be determined according to the HARQ-ACK retransmission codebook, 1 or 0 retran Equal to the number of bits in the HARQ-ACK retransmission codebook, nHARQ-ACK, 0 + nHARQ-ACK, 1 or nHARQ-ACK, 0 + 0 retran As n HARQ-ACK Determine the power of PUCCH.

[0117] The PUCCH power control parameter determination method provided in the present application determines the PUCCH power control parameter based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook when the configuration of the terminal device includes HARQ-ACK retransmission and the PUCCH only contains the HARQ-ACK retransmission codebook, or determines the PUCCH power control parameter based on the initial transmission codebook when the configuration of the terminal device includes HARQ-ACK retransmission and the PUCCH contains the HARQ-ACK retransmission codebook and the initial transmission codebook, thereby solving the technical problem in the related art that it is unclear how to determine the PUCCH power in the case of codebook cascading.

[0118] In order to clearly illustrate how to determine the PUCCH power control parameters when the configuration of the terminal device includes HARQ-ACK retransmission, an example is given below to illustrate.

[0119] As an example, for the case where HARQ-ACK codebook retransmission is configured, when HARQ-ACK is carried on PUCCH format 2 / 3 / 4 and the number of UCI feedback bits is greater than 2 and less than or equal to 11, the PUCCH power control parameter n can be determined based on the codebook transmission of HARQ-ACK on PUCCH. HARQ-ACK , thereby determining the power of PUCCH. HARQ-ACK The determination method is as follows:

[0120] Solution 1: nHARQ-ACK,0+nHARQ-ACK,1 or nHARQ-ACK,0+0 retran As n HARQ-ACK Determine the power of PUCCH.

[0121] If the PUCCH contains the initial transmission codebook, nHARQ-ACK,0 is determined based on the initial transmission codebook; otherwise, nHARQ-ACK,0 is equal to 0.

[0122] If the PUCCH contains the HARQ-ACK retransmission codebook, nHARQ-ACK, 1 is determined based on the HARQ-ACK retransmission or 0 retran Equal to the number of bits in the HARQ-ACK retransmission codebook, otherwise nHARQ-ACK, 1 or 0 retran Equal to 0.

[0123] That is, based on solution 1, the PUCCH power parameter n can be determined HARQ-ACK =nHARQ-ACK,0+nHARQ-ACK,1, or n HARQ-ACK =nHARQ-ACK, 0+0 retran , where nHARQ-ACK,0 is determined based on the initial transmission codebook, nHARQ-ACK,1 is determined based on the HARQ-ACK retransmission codebook, and O retran Equal to the number of bits in the HARQ-ACK retransmission codebook.

[0124] Solution 2: Determine n based on the codebook contained in the PUCCH HARQ-ACK , thereby determining the power of PUCCH. Specifically:

[0125] If the PUCCH only contains the HARQ-ACK retransmission codebook, then n HARQ-ACK Determined based on the HARQ-ACK retransmission codebook, or, n HARQ-ACK Equal to the number of bits in the HARQ-ACK retransmission codebook;

[0126] If the PUCCH contains both the HARQ-ACK retransmission codebook and the initial transmission codebook, then:

[0127] Solution 2-1: Determine n according to the initial codebook HARQ-ACK , without considering the HARQ-ACK retransmission codebook.

[0128] Solution 2-2: Determine nHARQ-ACK according to the initial transmission codebook, 0, and determine nHARQ-ACK according to the HARQ-ACK retransmission codebook, 1 or 0 retranEqual to the number of bits in the HARQ-ACK retransmission codebook, nHARQ-ACK, 0 + nHARQ-ACK, 1 or nHARQ-ACK, 0 + 0 retran As n HARQ-ACK Determine the power of PUCCH.

[0129] Therefore, assuming that the UE is configured with HARQ-ACK codebook retransmission and uses PUCCH format 2 / 3 / 4 to carry HARQ-ACK for transmission, when the PUCCH carries 0 ACK +O SR +O CSI When ≤11, the UE can determine the number of HARQ-ACK information bits used for PUCCH transmission power determination based on the above two schemes, that is, the PUCCH power control parameter n HARQ-ACK , when PUCCH carries O ACK +O SR +O CSI When >11, the UE may determine the number of HARQ-ACK information bits used for PUCCH transmission power determination based on the total number of bits in the cascaded HARQ-ACK codebook. ACK .

[0130] It should be noted that in the above scheme, nHARQ-ACK is determined based on the initial transmission codebook, 0 or n HARQ-ACK , and determine nHARQ-ACK based on the retransmission codebook, 1 or n HARQ-ACK If the initial codebook is a Type-1 HARQ-ACK codebook, then nHARQ-ACK,0, nHARQ-ACK,1 or n HARQ-ACK As defined in 3GPP TS 38.213 Section 9.1.2.1 or 16.5.1.1 HARQ-ACK ; If the initial codebook is Type-2 HARQ-ACK codebook, then nHARQ-ACK, 0, nHARQ-ACK, 1 or n HARQ-ACK As defined in 3GPP TS38.213 Section 9.1.3.1 or 9.1.3.3 or 16.5.2.1 HARQ-ACK .

[0131] In summary, for the case where HARQ-ACK codebook retransmission is configured, when HARQ-ACK is carried in PUCCH format 2 / 3 / 4 and the number of UCI feedback bits is greater than 2 and less than or equal to 11, the PUCCH power control parameter n can be determined based on the codebook transmission of HARQ-ACK on PUCCH. HARQ-ACK , ensuring the PUCCH transmission performance in this case.

[0132] In order to clearly illustrate how the PUCCH power control parameters are determined in this application when the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission, an embodiment of the present application provides a possible implementation method of the PUCCH power control parameter determination method. Figure 6 is a flow chart of the PUCCH power control parameter determination method provided according to the sixth embodiment of the present application.

[0133] As shown in FIG6 , the method for determining the PUCCH power control parameter may include the following steps:

[0134] Step 601: When the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission, determine the PUCCH power control parameter according to the first HARQ-ACK parameter, the second HARQ-ACK parameter and the third HARQ-ACK parameter.

[0135] It should be noted that when the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission, the codebook cascading conditions of the codebook included in the PUCCH include the following four cases:

[0136] Case 1: The PUCCH contains both the initial transmission codebook and the SPS delayed codebook, where the initial transmission codebook is the initial codebook, which refers to the initial HARQ-ACK bits in the target time slot.

[0137] The inclusion of both the initial transmission codebook and the SPS delayed codebook in the PUCCH means that there is an initial HARQ-ACK bit in the target time slot, and the delayed SPS HARQ-ACK feedback bit needs to be appended after the initial HARQ-ACK bit in the target time slot.

[0138] Case 2: The PUCCH contains both the initial transmission codebook and the HARQ-ACK retransmission codebook, where the initial transmission codebook is the initial codebook.

[0139] The inclusion of both the initial transmission codebook and the HARQ-ACK retransmission codebook in the PUCCH means that an initial Type-1 or Type-2 codebook may exist in the target retransmission time slot where the HARQ-ACK retransmission codebook is located, and the HARQ-ACK retransmission codebook is cascaded after the initial Type-1 or Type-2 codebook of the same priority.

[0140] It should be noted that, in case 2, there is no delayed SPS HARQ-ACK codebook in the target retransmission time slot.

[0141] Case 3: The PUCCH contains the initial transmission codebook, HARQ-ACK retransmission codebook and SPS delay codebook at the same time, among which the initial transmission codebook is the initial codebook.

[0142] The inclusion of the initial transmission codebook, the HARQ-ACK retransmission codebook, and the SPS delayed codebook in the PUCCH means that an initial Type-1 or Type-2 codebook may exist in the target retransmission time slot where the HARQ-ACK retransmission codebook is located. The HARQ-ACK retransmission codebook is cascaded after the initial Type-1 or Type-2 codebook of the same priority. However, since there is still a delayed SPS HARQ-ACK codebook in the target retransmission time slot at this time, the delayed SPS HARQ-ACK codebook needs to be attached to the HARQ-ACK retransmission codebook and the initial codebook, that is, there are three codebook information cascaded in this time slot, in the order of initial / new codebook, HARQ-ACK retransmission codebook, and SPS delayed codebook.

[0143] Case 4: The PUCCH contains both the HARQ-ACK retransmission codebook and the SPS delayed codebook. That is, the target retransmission time slot where the HARQ-ACK retransmission codebook is located does not contain the initial Type-1 or Type-2 codebook, and the HARQ-ACK retransmission codebook is transmitted directly in the target retransmission time slot. At this time, since the delayed SPS HARQ-ACK codebook still exists in the target retransmission time slot, the delayed SPS HARQ-ACK codebook needs to be appended to the HARQ-ACK retransmission codebook.

[0144] In addition to the above four codebook concatenation situations, the codebook transmission of HARQ-ACK on PUCCH may also have the following three situations:

[0145] Case 5: The PUCCH contains only the initial transmission codebook, that is, only the initial HARQ-ACK bits exist in the target time slot, and there is no delayed SPS HARQ-ACK codebook and / or HARQ-ACK retransmission codebook.

[0146] Case 6: The PUCCH contains only the SPS delayed codebook, that is, there is no initial HARQ-ACK bit in the target time slot. Only the delayed SPS HARQ-ACK feedback bits need to be transmitted in the target time slot.

[0147] Case 7: The PUCCH contains only the HARQ-ACK retransmission codebook. That is, the target retransmission time slot where the HARQ-ACK retransmission codebook is located does not contain the initial Type-1 or Type-2 codebook, nor does it contain the delayed SPS HARQ-ACK codebook. Therefore, the HARQ-ACK retransmission codebook only needs to be transmitted in the target retransmission time slot.

[0148] In which, when the PUCCH includes the initial transmission codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, and when the PUCCH does not include the initial transmission codebook, the first HARQ-ACK parameter is a first fixed value.

[0149] The first fixed value can be selected based on actual needs in the embodiment of the present application. Optionally, the first fixed value can be set based on manual experience, for example, the first fixed value can be set to 0, or the first fixed value can be dynamically adjusted based on actual application requirements. In the embodiment of the present application, the selection can be based on actual needs.

[0150] When the SPS delay codebook is included in the PUCCH, the second HARQ-ACK parameter is determined based on the number of bits of the SPS delay codebook. When the SPS delay codebook is not included in the PUCCH, the seventh HARQ-ACK parameter is a second fixed value.

[0151] Similarly, the value of the second fixed value can be selected according to actual needs in the embodiment of the present application. Optionally, the second fixed value can be set based on manual experience, for example, the second fixed value can be set to 0, or the second fixed value can be dynamically adjusted according to actual application requirements. In the embodiment of the present application, the selection can be made according to actual needs.

[0152] When the HARQ-ACK retransmission codebook is included in the PUCCH, the third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook. When the HARQ-ACK retransmission codebook is not included in the PUCCH, the third HARQ-ACK parameter is a third fixed value.

[0153] Similarly, the value of the third fixed value can be selected according to actual needs in the embodiment of the present application. Optionally, the third fixed value can be set based on manual experience, for example, the third fixed value can be set to 0, or the third fixed value can be dynamically adjusted according to actual application requirements. In the embodiment of the present application, the selection can be made according to actual needs.

[0154] In some embodiments, when the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission, the sum of the first HARQ-ACK parameter, the second HARQ-ACK parameter and the third HARQ-ACK parameter can be determined as the PUCCH power control parameter. Thus, through the description of the values ​​of the first HARQ-ACK parameter, the second HARQ-ACK parameter and the third HARQ-ACK parameter, it can be seen that for the above situation one, since the PUCCH contains both the initial transmission codebook and the SPS delay codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, the second HARQ-ACK parameter is determined based on the number of bits of the SPS delay codebook, and the third HARQ-ACK parameter is a third fixed value. At this time, the PUCCH power control parameter is the sum of the first HARQ-ACK parameter, the second HARQ-ACK parameter and the third fixed value; for the above situation two, since the PUCCH contains the same When the initial transmission codebook and the HARQ-ACK retransmission codebook are included, the first HARQ-ACK parameter is determined based on the initial transmission codebook, the second HARQ-ACK parameter is the second fixed value, and the third HARQ-ACK parameter is based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook. At this time, the PUCCH power control parameter is the sum of the first HARQ-ACK parameter, the second fixed value and the third HARQ-ACK parameter; for the above situation three, since the PUCCH contains the initial transmission codebook, the HARQ-ACK retransmission codebook and the SPS delay codebook at the same time, the first HARQ-ACK parameter is based on the initial transmission codebook Determine, the second HARQ-ACK parameter is determined based on the number of bits of the SPS delay codebook, and the third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook. At this time, the PUCCH power control parameter is the sum of the first HARQ-ACK parameter, the second HARQ-ACK parameter, and the third HARQ-ACK parameter; for the above situation four, since the PUCCH contains both the HARQ-ACK retransmission codebook and the SPS delay codebook, the first HARQ-ACK parameter is a first fixed value, and the second HARQ-ACK parameter is determined based on the number of bits of the SPS delay codebook. The third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook. At this time, the PUCCH power control parameter is the sum of the first fixed value, the second HARQ-ACK parameter, and the third HARQ-ACK parameter. For the above situation one, since the PUCCH only contains the initial transmission codebook, the first HARQ-ACK parameter is determined based on the initial transmission codebook, the second HARQ-ACK parameter is the second fixed value, and the third HARQ-ACK parameter is the third fixed value. At this time, the PUCCH power control parameter is the sum of the first HARQ-ACK parameter, the second fixed value, and the third fixed value.For the above situation six, since the PUCCH only includes the SPS delay codebook, the first HARQ-ACK parameter is the first fixed value, the second HARQ-ACK parameter is determined based on the number of bits in the SPS delay codebook, and the third HARQ-ACK parameter is the third fixed value. In this case, the PUCCH power control parameter is the sum of the first fixed value, the second HARQ-ACK parameter, and the third fixed value. For the above situation seven, since the PUCCH only includes the HARQ-ACK retransmission codebook, the first HARQ-ACK parameter is the first fixed value, the second HARQ-ACK parameter is the second fixed value, and the third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits in the HARQ-ACK retransmission codebook. In this case, the PUCCH power control parameter is the sum of the first fixed value, the second fixed value, and the third HARQ-ACK parameter.

[0155] As an example, it is assumed that the first HARQ-ACK parameter is represented by nHARQ-ACK,0 and the second HARQ-ACK parameter is represented by 0 SPS Indicates that the third HARQ-ACK parameter is nHARQ-ACK, 1 or 0 retran Indicates that the PUCCH power control parameter is expressed as n HARQ-ACK Indicates that nHARQ-ACK, 0+0 SPS +nHARQ-ACK, 1 or nhARQ-ACK, 0+0 SPS +O retran As n HARQ-ACK Determine the power of PUCCH. If the PUCCH contains the initial transmission codebook, nHARQ-ACK,0 is determined based on the initial transmission codebook, otherwise nHARQ-ACK,0 is equal to 0; if the PUCCH contains the HARQ-ACK retransmission codebook, nHARQ-ACK,1 is determined based on the HARQ-ACK retransmission codebook or 0 retran Equal to the number of bits in the HARQ-ACK retransmission codebook, otherwise nHARQ-ACK, 1 or 0 retran Equal to 0; if PUCCH contains SPS delay codebook, 0 SPS Equal to the number of bits in the SPS delay codebook, otherwise O SPS Equal to 0.

[0156] The PUCCH power control parameter determination method provided in the present application determines the PUCCH power control parameter according to the first HARQ-ACK parameter, the second HARQ-ACK parameter and the third HARQ-ACK parameter when the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission, thereby solving the technical problem in the related art of how to determine the PUCCH power in the case of codebook cascading.

[0157] The previous embodiment described a possible implementation method for determining PUCCH power control parameters when the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission. The embodiment of the present application provides another possible implementation method for determining PUCCH power control parameters when the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission. Figure 7 is a flow chart of the PUCCH power control parameter determination method provided according to the seventh embodiment of the present application.

[0158] As shown in FIG7 , the method for determining the PUCCH power control parameter may include the following steps:

[0159] Step 701: When the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission, determine the PUCCH power control parameter based on the first HARQ-ACK parameter, the number of bits of the HARQ-ACK retransmission codebook, the number of bits of the SPS delay codebook, the first parameter, and the second parameter.

[0160] The first HARQ-ACK parameter is determined based on the initial transmission codebook when the PUCCH includes the initial transmission codebook.

[0161] The first parameter and the second parameter are predefined or configured by high-level parameters. Optionally, the value range of the first parameter and the second parameter is [0, 1].

[0162] In some embodiments, when the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission, the product of the number of bits of the HARQ-ACK retransmission codebook and the first parameter can be determined as the first intermediate value, and the product of the number of bits of the SPS delay codebook and the second parameter can be determined as the second intermediate value, thereby determining the sum of the first HARQ-ACK parameter, the first intermediate value and the second intermediate value as the PUCCH power control parameter.

[0163] As an example, it is assumed that the first HARQ-ACK parameter is represented by nHARQ-ACK,0, and the number of bits of the HARQ-ACK retransmission codebook is represented by 0. retran Indicates that the number of bits of the SPS delay codebook is O SPS The first parameter is represented by α, and the second parameter is represented by β, then the PUCCH power control parameter n is determined HARQ-ACK The calculation of is as follows:

At this time, if the first fixed value and the third fixed value are both 0, the PUCCH power control parameter is equal to 0+second HARQ-ACK parameter+0, that is, the PUCCH power control parameter is equal to the second HARQ-ACK parameter, that is, the PUCCH power control parameter is determined based on the number of bits of the SPS delay codebook, which is consistent with the scheme provided in this step; if the first fixed value and / or the third fixed value is not 0, the PUCCH power control parameter is the sum of the first fixed value (non-zero value), the second HARQ-ACK parameter, and the third fixed value (non-zero value), which is different from the scheme provided in this step.

[0175] It should be noted that, for the embodiment shown in Figure 6, when the configuration of the terminal device includes SPS delay and HARQ-ACK retransmission and the PUCCH only contains the HARQ-ACK retransmission codebook, the first HARQ-ACK parameter is a first fixed value, the second HARQ-ACK parameter is a second fixed value, the third HARQ-ACK parameter is determined based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook, and the PUCCH power control parameter is the sum of the first fixed value, the second fixed value and the third HARQ-ACK parameter. At this time, if the first fixed value and the second fixed value are both 0, the PUCCH power control parameter is equal to 0+0+the third HARQ-ACK parameter, that is, the PUCCH power control parameter is equal to the third HARQ-ACK parameter, that is, the PUCCH power control parameter is based on the HARQ-ACK retransmission codebook or the number of bits of the HARQ-ACK retransmission codebook, which is consistent with the scheme provided in this step; if the first fixed value and / or the second fixed value is not 0, the PUCCH power control parameter is the sum of the first fixed value (non-zero value), the second fixed value (non-zero value) and the third HARQ-ACK parameter, which is different from the scheme provided in this step.

[0250] Scheme 6-2: n HARQ-ACK Equal to the number of bits in the SPS delay codebook, ignoring the HARQ-ACK retransmission codebook;

[0252] Therefore, assuming that the UE is configured with HARQ-ACK codebook retransmission and uses PUCCH format 2 / 3 / 4 to carry HARQ-ACK for transmission, when the PUCCH carries 0 ACK +O SR +O CSI When ≤11, the UE can determine the number of HARQ-ACK information bits used for PUCCH transmission power determination based on the above three schemes, that is, the PUCCH power control parameter n HARQ-ACK , when PUCCH carries O ACK +O SR +OCSI When >11, the UE may determine the number of HARQ-ACK information bits used for PUCCH transmission power determination based on the total number of bits in the cascaded HARQ-ACK codebook. ACK .

[0253] It should be noted that in the above scheme, nHARQ-ACK is determined based on the initial transmission codebook, 0 or n HARQ-ACK , and determine nHARQ-ACK based on the retransmission codebook, 1 or n HARQ-ACK If the initial codebook is a Type-1 HARQ-ACK codebook, then nHARQ-ACK,0, nHARQ-ACK,1 or n HARQ-ACK As defined in 3GPP TS 38.213 Section 9.1.2.1 or 16.5.1.1 HARQ-ACK ; If the initial codebook is Type-2 HARQ-ACK codebook, then nHARQ-ACK, 0, nHARQ-ACK, 1 or n HARQ-ACK As defined in 3GPP TS38.213 Section 9.1.3.1 or 9.1.3.3 or 16.5.2.1 HARQ-ACK .
