[0050] The following description, in conjunction with the accompanying drawings, details a message processing method, apparatus, device, and storage medium provided in this application through some embodiments and application scenarios.

[0051] Please see Figure 2 , Figure 2 This is a flowchart of a method for determining a transmission mode provided in an embodiment of this application, such as... Figure 2 As shown, it includes the following steps:

[0052] Step 201: The terminal receives configuration information sent by the network-side device;

[0053] Step 202: The terminal selects the target transmission mode for transmitting the Physical Uplink Control Channel (PUCCH) from among multiple transmission modes according to the configuration information;

[0054] Among them, the transmission methods of the multiple transmission methods satisfy at least one of the following:

[0055] The PUCCH associated spatial relationship information;

[0056] The PUCCH associated power control parameter set.

[0057] The configuration information mentioned above can be static, dynamic, or semi-static configuration information provided to the terminal by network-side devices. It can be higher-layer parameters, such as configuration information provided to the terminal via radio resource control (RRC) signaling. The configuration information can explicitly or implicitly indicate the target transmission method.

[0058] The above-mentioned multiple transmission methods may include at least two of the following:

[0059] A transmission method that satisfies the requirement of PUCCH associating spatial relationship information;

[0060] The transmission method that satisfies the association of N spatial relationship information by PUCCH;

[0061] A transmission method that satisfies the requirement of associating a power control parameter set with the PUCCH;

[0062] It satisfies the transmission mode of PUCCH associated with N sets of power control parameters.

[0063] Furthermore, in some embodiments of this application, the following can be satisfied in some transmission methods: PUCCH is associated with N spatial relationship information and PUCCH is associated with N power control parameter sets; or, in some transmission methods, PUCCH is associated with N spatial relationship information and PUCCH is associated with one power control parameter set; or, in some transmission methods, PUCCH is associated with one spatial relationship information and PUCCH is associated with one power control parameter set; or, in some transmission methods, PUCCH is associated with one spatial relationship information and PUCCH is associated with N power control parameter sets; or, in some transmission methods, PUCCH is associated with one or N power control parameter sets. The specific method is not limited in this regard.

[0064] In this embodiment of the application, the spatial relationship information may include a reference signal indicating the beam. The beam corresponding to the spatial relationship information can be determined through the reference signal. Furthermore, the spatial relationship information may also instruct the terminal to calculate the power control parameters for transmitting power.

[0065] In this embodiment of the application, a spatial relationship information can be associated with a TRP. In this way, when the PUCCH is associated with multiple spatial relationship information in the transmission mode, the PUCCH can be transmitted to the corresponding multiple TRPs to improve the transmission reliability of the PUCCH.

[0066] In this embodiment of the application, the power control parameter set may include power control parameters for determining the PUCCH, including at least one of the following:

[0067] Target received power P0, path loss reference signal (PL-RS), and closed-loop power control adjustment state l.

[0068] For the transmission method of PUCCH associated with N power control parameter sets, this realizes the transmission of PUCCH based on N power control parameter sets, thereby improving the transmission reliability of PUCCH. For example, PUCCH is transmitted to N TRPs based on N power control parameter sets respectively.

[0069] In this embodiment of the application, the above steps enable the terminal to select the PUCCH transmission mode from the above multiple transmission modes according to the configuration information, thereby improving the flexibility of the terminal in transmitting PUCCH.

[0070] In some implementations, N is 2, but this is not a limitation. For example, in other implementations, N may be greater than 2, such as 3 or 4.

[0071] In this embodiment, after step 201, the terminal can transmit the PUCCH according to the above-described target transmission method. Furthermore, some transmission methods can improve the transmission reliability of the PUCCH. For example, the target transmission method satisfies the transmission method of PUCCH associating with N spatial relationship information, thus enabling the transmission of PUCCH to N TRPs / beams, thereby improving the transmission reliability of the PUCCH. As another example, the target transmission method satisfies the transmission method of PUCCH associating with N power control parameter sets, thus enabling the transmission of PUCCH based on N power control parameter sets, which also improves the transmission reliability of the PUCCH.

[0072] As an optional implementation method, the above-mentioned multiple transmission methods include at least two of the following:

[0073] First transmission method, second transmission method, third transmission method;

[0074] Wherein, in the first transmission mode, the following conditions are met: the transmission timing of the PUCCH is associated with one spatial relationship information or N spatial relationship information, and / or, the transmission timing of the PUCCH is associated with one power control parameter set or N power control parameter sets, and one time slot includes one transmission timing;

[0075] In the second transmission mode, the following conditions are met: one transmission time of the PUCCH is associated with N spatial relationship information, and / or, one transmission time of the PUCCH is associated with N power control parameter sets;

[0076] Wherein, in the third transmission mode, the following conditions are met: the transmission timing of the PUCCH is associated with one spatial relationship information or N spatial relationship information, and / or, the transmission timing of the PUCCH is associated with one power control parameter set or N power control parameter sets, and a sub-slot includes one transmission timing;

[0077] N is an integer greater than 1.

[0078] The above-mentioned first transmission method satisfies: the transmission timing of the PUCCH is associated with one spatial relationship information or N spatial relationship information, and / or the transmission timing of the PUCCH is associated with one power control parameter set or N power control parameter sets. One time slot including one transmission timing can be understood as any of the following methods:

[0079] In the first transmission method, the transmission timing that satisfies the PUCCH is associated with one spatial relationship information or N spatial relationship information;

[0080] In the first transmission mode, the transmission timing that satisfies the PUCCH is associated with one power control parameter set or N power control parameter sets;

[0081] In the first transmission mode, the transmission timing that satisfies the PUCCH is associated with a spatial relationship information and with a power control parameter set or N power control parameter sets;

[0082] In the first transmission mode, the transmission timing that satisfies the PUCCH is associated with N spatial relationship information and with a power control parameter set or N power control parameter sets.

[0083] This allows the time-slot-based PUCCH to associate up to N spatial relationship information or up to N power control parameter sets in the first transmission mode.

[0084] The same applies to the third transmission method mentioned above, which will not be elaborated here. In the third transmission method, the PUCCH based on sub-time slots can be associated with up to N spatial relationship information, or up to N sets of power control parameters.

[0085] In this embodiment, one transmission opportunity corresponds to one repeated transmission. Multiple transmission opportunities of PUCCH can be multiple repeated transmissions of PUCCH. For example, in the first transmission mode, when multiple repeated transmissions of PUCCH are associated with N spatial relationship information, these multiple repeated transmissions can be transmitted to the TRP / beams corresponding to the N spatial relationship information respectively. For example, if N=2, these multiple repeated transmissions can be cyclically mapped to two TRP / beams, or these multiple repeated transmissions can be sequentially mapped to two TRP / beams.

[0086] The aforementioned time slot can include a transmission opportunity, with one transmission opportunity corresponding to one time slot, and different transmission opportunities corresponding to different time slots. This enables the first transmission method to be used for time slot-based PUCCH transmission.

[0087] The aforementioned sub-time slot can include a transmission opportunity, with one transmission opportunity corresponding to one sub-time slot, and different transmission opportunities corresponding to different sub-time slots. This enables a third transmission method for PUCCH transmission based on sub-time slots.

[0088] The above-mentioned second transmission mode satisfies that: one transmission time of the PUCCH is associated with N spatial relationship information, and / or, one transmission time of the PUCCH is associated with N power control parameter sets, which can be understood as any of the following:

[0089] In the second transmission method, a transmission timing that satisfies the PUCCH is associated with N spatial relationship information;

[0090] In the second transmission mode, a transmission timing that satisfies the PUCCH is associated with N sets of power control parameters;

[0091] In the second transmission mode, a transmission timing that satisfies the PUCCH is associated with N spatial relationship information and N sets of power control parameters.

[0092] This allows the PUCCH to associate with N spatial relationship information or N sets of power control parameters in the second transmission mode.

[0093] In the above embodiments, the first transmission method, the second transmission method, and the third transmission method can enable the terminal to support more transmission methods, thereby further improving the flexibility of the terminal in transmitting PUCCH.

[0094] Optionally, the first transmission method or the third transmission method satisfies at least one of the following:

[0095] When the network-side device activates the PUCCH resource of the PUCCH or indicates N spatial relationship information, the multiple transmission opportunities of the PUCCH are respectively associated with the spatial relationship information in the N spatial relationship information;

[0096] When the network-side device activates or indicates a spatial relationship information for the PUCCH resource of the PUCCH, one or more transmission opportunities of the PUCCH are associated with the spatial relationship information.

[0097] When the network-side device activates the PUCCH resource for the PUCCH or indicates N power control parameter sets, the multiple transmission opportunities of the PUCCH are respectively associated with the power control parameter sets in the N power control parameter sets;

[0098] When the network-side device activates or indicates a power control parameter set for the PUCCH resource, one or more transmission events of the PUCCH are associated with the power control parameter set.

[0099] The spatial relationship information for activating or indicating the PUCCH resource can be activated or indicated through a Media Access Control Element (MAC CE). For example, the configuration information configures multiple spatial relationship information for the PUCCH resource, and N or one of these spatial relationship information is activated or indicated through the MAC CE. Of course, in some embodiments, the spatial relationship information of the PUCCH resource can also be activated or indicated directly by the above configuration information.

[0100] The power control parameter set activated or indicated by the PUCCH resource can also be activated or indicated via MAC CE. For example, the configuration information configures multiple power control parameter sets for the PUCCH resource, and N or one of these power control parameter sets are activated or indicated via MAC CE. Of course, in some implementations, the power control parameter set of the PUCCH resource can also be activated or indicated directly by the above configuration information.

[0101] The multiple transmission opportunities of the PUCCH can be associated with the spatial relationship information in the N spatial relationship information respectively. This can be achieved by: (1) when there are N transmission opportunities, each of the N transmission opportunities is associated with a different spatial relationship information in the N spatial relationship information; or (2) when there are more than N transmission opportunities, the multiple transmission opportunities are associated with the N spatial relationship information in a cyclic or sequential manner. For example, if N=2, the multiple transmission opportunities can be cyclically mapped to the TRP / beam corresponding to two spatial relationship information, or the multiple transmission opportunities can be sequentially mapped to the TRP / beam corresponding to two spatial relationship information.

[0102] For example: Figure 3 As shown, the four transmission opportunities correspond to time slots n, n+1, n+2, and n+3, respectively. When two spatial relationship information is activated, the transmission opportunities of time slots n and n+1 (i.e., Figure 3 The spatial relationship information corresponding to Rep#1 and Rep#2 in the data, and the transmission timing of time slot n+2 and time slot n+3 (i.e., Figure 3 The spatial relationship information corresponding to Rep#3 and Rep#4 in the image is associated with beam 2. Therefore, the transmission timing of time slot n and time slot n+1 is mapped to beam 1, and the transmission timing of time slot n+2 and time slot n+3 is mapped to beam 2.

[0103] When a spatial relationship is activated, the transmission timing of time slot n, time slot n+1, time slot n+2, and time slot n+3 (i.e., Figure 3 The spatial relationship information of Rep#1, Rep#2, Rep#3 and Rep#4 in the image is associated with beam 1. Therefore, the transmission timing of time slot n, time slot n+1, time slot n+2 and time slot n+3 is mapped to beam 1.

[0104] For example: Figure 4 As shown, the four transmission opportunities correspond to time slot n and time slot n+1, respectively (i.e., ... Figure 4 Rep#1, Rep#2, Rep#3, and Rep#4 in the table, each transmission opportunity corresponds to a sub-slot. When two spatial relationship information is activated, the two transmission opportunities in slot n (i.e., Figure 4 Rep#1 and Rep#2 in the table are associated with the spatial relationship information corresponding to beam 1 and beam 2, respectively, and the two transmission opportunities in time slot n+1 (i.e. Figure 4 Rep#3 and Rep#4 in the table are associated with the spatial relationship information corresponding to beam 1 and beam 2, respectively. Therefore, the transmission opportunities of the two time slots n are mapped to beam 1 and beam 3, respectively, and the two transmission opportunities of time slot n+1 are mapped to beam 1 and beam 2, respectively.

[0105] When a spatial relationship information is activated, the four transmission opportunities of time slot n and time slot n+1 (i.e. Figure 4 The spatial relationship information of Rep#1, Rep#2, Rep#3 and Rep#4 in the image is associated with beam 1. Therefore, the four transmission opportunities of time slot n and time slot n+1 are mapped to beam 1.

[0106] Associating the power control parameter sets in the N power control parameter sets during the multiple transmission opportunities of the above PUCCH can be as follows: when there are N transmission opportunities, these N transmission opportunities are associated with different power control parameter sets in the N power control parameter sets respectively; or when there are more than N transmission opportunities, these multiple transmission opportunities are associated with the above N power control parameter sets cyclically or sequentially. For example, if N=2, these multiple transmission opportunities are associated with two power control parameter sets cyclically, or these multiple transmission opportunities are associated with two power control parameter sets sequentially.

[0107] In this embodiment, in the first and third transmission modes, the spatial relationship information associated with the PUCCH transmission timing can be determined based on the actual activated or indicated spatial relationship information, and the power control parameter set associated with the PUCCH transmission timing can be determined based on the actual activated or indicated power control parameter set, thereby further improving the flexibility of PUCCH transmission.

[0108] Optionally, the second transmission method satisfies at least one of the following:

[0109] When a PUCCH transmission occurs in a manner that includes M frequency hopping resources, the PUCCH associates the spatial relationship information from the N spatial relationship information on each of the M frequency hopping resources.

[0110] When a transmission event of a PUCCH includes M frequency hopping resources, the PUCCH is associated with power control parameter sets from the N power control parameter sets on the M frequency hopping resources, where M is an integer greater than 1.

[0111] In some implementations, M is 2, but this is not a limitation; for example, in other implementations, M is 4.

[0112] The M frequency hopping resources mentioned above can be associated with the spatial relationship information in the N spatial relationship information respectively. When M equals N, the M frequency hopping resources can be associated with different spatial relationship information in the N spatial relationship information respectively. Alternatively, when M is greater than N, the M frequency hopping resources can be associated with the N spatial relationship information in a cyclical or sequential manner.

[0113] In the second transmission method, the PUCCH associated with the power control parameter sets in the N power control parameter sets in the M frequency hopping resources can be, when M equals N, that the M frequency hopping resources are associated with different power control parameter sets in the N power control parameter sets, or when M is greater than N, that the M frequency hopping resources are associated with the N power control parameter sets in a cyclic or sequential manner.

[0114] Taking M=2 as an example, such as Figure 5 As shown, a transmission opportunity includes two frequency hopping resources (i.e. Figure 5 As shown, Hop1 and Hop2 are two frequency hopping resources that are associated with the spatial relationship information of beam 1 and beam 2, respectively. Therefore, these two frequency hopping resources are mapped to beam 1 and beam 2, respectively.

[0115] In this implementation, PUCCH can be transmitted to TRP / beams corresponding to different spatial relationship information for the same transmission time, or PUCCH can be transmitted based on different power control parameter sets for the same transmission time, thereby improving the transmission reliability of PUCCH.

[0116] As an optional implementation, the terminal selects a target transmission mode for transmitting PUCCH from a variety of transmission modes based on the configuration information, including at least one of the following:

[0117] Under a first condition, the third transmission method is selected for the PUCCH among the multiple transmission methods, wherein the first condition includes: the configuration information includes the subslot length of the PUCCH resource of the PUCCH;

[0118] Under the second condition, the second transmission mode is selected for the PUCCH among the multiple transmission modes. The second condition includes at least one of the following: the number of repetitions is 1, the side configuration information does not include the sub-slot length of the PUCCH resource of the PUCCH, and the configuration information includes the intra-slot hopping information of the PUCCH resource.

[0119] If the first condition or the second condition is not met, the first transmission method is selected for the PUCCH among the multiple transmission methods.

[0120] The second transmission method mentioned above can be configured under the condition that frequency hopping within a time slot is configured in the PUCCH resource, and the third transmission method mentioned above can be configured under the condition that the sub-time slot length is configured.

[0121] The above repetition count of 1 could mean that the network side has not configured a repetition count, or that the configured repetition count is 1.

[0122] In this embodiment, when a sub-slot length is configured, the PUCCH is transmitted according to the third transmission method. When no sub-slot length is configured, no repetition count is configured, or the repetition count is 1, and intra-slot frequency hopping is configured, and the PUCCH resource is associated with N spatial relationship information or N power control parameter sets, the PUCCH is transmitted according to the second transmission method. In other cases, the PUCCH is transmitted according to the first transmission method.

[0123] In this implementation, the corresponding transmission method can be selected according to the first and second conditions mentioned above, so as to further improve the flexibility of PUCCH transmission.

[0124] Optionally, the terminal selects a target transmission mode for transmitting PUCCH from among multiple transmission modes based on the configuration information, including at least one of the following:

[0125] Under the third condition, the third transmission mode is selected for the PUCCH among the multiple transmission modes, and the third condition includes: the side configuration information includes the sub-slot length of the PUCCH resource of the PUCCH;

[0126] If the third condition is not met, the first transmission method is selected for the PUCCH among the multiple transmission methods.

[0127] In this implementation, when the sub-slot length is configured, the PUCCH is transmitted according to the third transmission method, while in other cases the PUCCH is transmitted according to the first transmission method, thereby further improving the flexibility of PUCCH transmission.

[0128] As an optional implementation, the terminal selects the target transmission mode of PUCCH from a variety of transmission modes based on the configuration information, including at least one of the following:

[0129] Under the fourth condition, the second transmission mode is selected for the PUCCH among the multiple transmission modes. The fourth condition includes at least one of the following: the repetition count is 1, the configuration information does not include the sub-slot length of the PUCCH resource of the PUCCH, and the configuration information includes the intra-slot frequency hopping information of the PUCCH resource.

[0130] If the fourth condition is not met, the first transmission method is selected for the PUCCH among the multiple transmission methods.

[0131] In some implementations, the PUCCH may be transmitted in the second transmission mode when no sub-slot length is configured, no repetition count is configured or the repetition count is 1, intra-slot frequency hopping is configured, and the PUCCH resource is associated with N spatial relationship information or N power control parameter sets; otherwise, the PUCCH may be transmitted in the first transmission mode.

[0132] In this embodiment, the transmission method of PUCCH can be flexibly selected according to the fourth condition mentioned above, so as to further improve the flexibility of PUCCH transmission.

[0133] As an optional implementation, the configuration information includes a transmission mode indication parameter, which is used to indicate the target transmission mode.

[0134] The transmission mode indication parameter mentioned above can be an RRC parameter, used to explicitly indicate the transmission mode of PUCCH.

[0135] Optionally, the transmission mode indication parameter is associated with the PUCCH resource.

[0136] The aforementioned transmission mode indication parameters can be included in the PUCCH resource configuration, and different transmission modes can be configured for different PUCCH resources.

[0137] In this embodiment, since the transmission mode indication parameter is associated with the PUCCH resource, the transmission mode can be configured at the PUCCH resource level, thereby further improving the flexibility of PUCCH transmission.

[0138] As an optional implementation, at least one of the following PUCCH resources of the PUCCH is indicated by the MAC CE:

[0139] The amount of associated spatial relationship information;

[0140] Number of associated power control parameter sets.

[0141] For example, MAC CE can be used to configure PUCCH resources to associate with one or more spatial relationship information, and MAC CE can also be used to configure PUCCH resources to associate with one or more power control parameter sets.

[0142] In this implementation, the number of spatial relationship information associated with PUCCH resources and the number of associated power control parameter sets can be flexibly configured through MAC CE to improve the flexibility of PUCCH transmission.

[0143] As an optional implementation, the configuration information includes configuration information for the PUCCH resource configuration of the PUCCH.

[0144] The PUCCH resource configuration mentioned above can configure relevant information about PUCCH resources, such as spatial relationship information associated with PUCCH resources and power control parameter sets.

[0145] As an optional implementation, the method further includes:

[0146] The terminal determines the number of times the PUCCH will be repeatedly transmitted based on the configuration information.

[0147] The above configuration information can be used to explicitly or implicitly indicate the number of times the PUCCH is repeatedly transmitted.

[0148] Optionally, the terminal determines the number of times the PUCCH is repeatedly transmitted based on the configuration information, including at least one of the following:

[0149] Under the fifth condition, the first number of repeated transmissions of the PUCCH is determined, the fifth condition including: the configuration information includes the first number of repeated transmissions, wherein the first number of repeated transmissions is associated with the PUCCH resource of the PUCCH, or the first number of repeated transmissions is associated with the PUCCH format associated with the PUCCH resource of the PUCCH;

[0150] Under the sixth condition, a second number of retransmissions of the PUCCH is determined, the sixth condition including: the configuration information includes the second number of retransmissions, wherein the second number of retransmissions is associated with the PUCCH format of the PUCCH;

[0151] If the fifth or sixth condition is not met, the number of times the PUCCH is repeatedly transmitted is determined to be 1.

[0152] For example: if the network side configures a first repeated transmission count, and the first repeated transmission count is associated with the PUCCH resource or the PUCCH format associated with the PUCCH resource, then the repeated transmission count of the PUCCH is the first repeated transmission count.

[0153] If no first repeat transmission count is configured, but a second repeat transmission count is configured, and the second repeat transmission count is associated with the PUCCH format, then the repeat transmission count of the PUCCH is the second repeat transmission count.

[0154] In all other cases besides the two mentioned above, the PUCCH is transmitted 1 time.

[0155] The above PUCCH format is the same as the above PUCCH format.

[0156] In this implementation, a predetermined number of PUCCH retransmissions can be associated with PUCCH resources or PUCCH format, thereby improving the reliability of PUCCH transmission.

[0157] As an optional implementation, the method further includes:

[0158] The terminal determines the power control parameters of the PUCCH, wherein the power control parameters include at least one of the following:

[0159] Target received power (P0), PL-RS, closed-loop power control adjustment status (l).

[0160] The power control parameters of the PUCCH can be determined by determining the power control parameters of the PUCCH based on the configuration information, or by determining them based on the spatial relationship information or the set of power control parameters corresponding to the PUCCH resources.

[0161] Optionally, the terminal determines the power control parameters of the PUCCH, including one of the following:

[0162] When the PUCCH resource is activated or spatial relationship information is indicated, the target reception power of the PUCCH is determined to be the target reception power associated with the spatial relationship information.

[0163] If the PUCCH resource of the PUCCH is not activated or does not indicate spatial relationship information, but is activated or indicates a set of power control parameters, the target received power of the PUCCH is determined to be the target received power associated with the set of power control parameters.

[0164] If the PUCCH resource of the PUCCH is not activated or does not indicate spatial relationship information, and if the power control parameter set is not activated or indicated, the target received power of the PUCCH is determined to be the target received power of the first preset index in the target received power set.

[0165] When the above-mentioned PUCCH resources are activated or indicate N spatial relationship information, the target received power corresponding to the PUCCH transmission of each spatial relationship information is the target received power associated with that space.

[0166] The target received power associated with the aforementioned spatial relationship information can be the target received power of the TRP / beam corresponding to the spatial relationship information. Alternatively, the target received power associated with the spatial relationship information can be the target received power indicated by the spatial relationship information.

[0167] When the aforementioned PUCCH resource is activated or indicates N sets of power control parameters, the target received power corresponding to the PUCCH transmission for each power control parameter set is its associated target received power. The target received power associated with a power control parameter set can be the target received power explicitly or implicitly indicated by the power control parameter set.

[0168] The aforementioned target received power set can be pre-configured, and the aforementioned first preset index can be the smallest index in the target received power set, or the default index.

[0169] In this implementation, if the PUCCH resource activates spatial relationship information, then the P0 associated with the spatial relationship information is used; if the spatial relationship information is not activated, but the power control parameter set is activated, then the P0 associated with the power control parameter set is used; otherwise, the first preset index P0 in the P0 set is used, so as to flexibly determine the target received power according to the situation of the PUCCH resource.

[0170] Optionally, the terminal determines the power control parameters of the PUCCH, including one of the following:

[0171] When the PUCCH resource is activated or spatial relationship information is indicated, the PL-RS of the PUCCH is determined to be the PL-RS associated with the spatial relationship information;

[0172] If the PUCCH resource of the PUCCH is not activated or does not indicate spatial relationship information, but is activated or indicates a set of power control parameters, the PL-RS of the PUCCH is determined to be the PL-RS associated with the set of power control parameters.

[0173] If the configuration information includes PL-RS sequences (pathlossReferenceRSs), the PL-RS of the PUCCH is determined to be the PL-RS with the second preset index in the PL-RS sequence;

[0174] If the configuration information includes an indication to enable DefaultBeamPL-ForPUCCH, the PL-RS of the PUCCH is determined as the target PL-RS. The target PL-RS includes: a preset type of periodic reference signal associated with the quasi-co-location (QCL) assumption of the control resource set (COREEST) of the third preset index, or a preset type of periodic reference signal associated with the transmission configuration indication (TCI) status of the control resource set (COREEST) of the third preset index.

[0175] When the above PUCCH resource is activated or indicates N spatial relationship information, the PL-RS corresponding to the PUCCH transmission of each spatial relationship information is its respective associated PL-RS.

[0176] The PL-RS associated with the aforementioned spatial relationship information can be the PL-RS of the TRP / beam corresponding to the spatial relationship information. Alternatively, the PL-RS associated with the spatial relationship information can be the PL-RS indicating the spatial relationship information.

[0177] When the aforementioned PUCCH resource is activated or indicates N power control parameter sets, the PL-RS corresponding to the PUCCH transmission for each power control parameter set is its respective associated PL-RS. The PL-RS associated with the power control parameter set can be the PL-RS explicitly or implicitly indicated by the power control parameter set.

[0178] The configuration information mentioned above, including the indication to enable default beam loss for PUCCH, can be understood as the network-side device configuring the aforementioned terminal with default beam loss enabled for PUCCH.

[0179] The second preset index mentioned above can be index 0 or other indexes. There are no restrictions on this, and it can be set according to the actual situation.

[0180] The aforementioned third preset index can be the minimum index in the COREEST set corresponding to the terminal, or other indexes. There are no restrictions on this, and it can be set according to the actual situation.

[0181] The aforementioned preset type of periodic reference signal can be the type D periodic reference signal defined in the protocol. There are no restrictions on this, and it can be set according to the actual situation.

[0182] The above implementation method can achieve the following: if the PUCCH resource activates the spatial relationship information, the PL-RS associated with the spatial relationship information is used; if the spatial relationship information is not activated, but the power control parameter set is activated, the PL-RS associated with the power control parameter set is used; if a path loss reference signal sequence (pathlossReferenceRSs) is configured, the PL-RS with the second preset index is used as the default PL-RS. This allows for flexible determination of the PL-RS based on the PUCCH resource or network-side configuration.

[0183] Optionally, when the configuration information includes an indication to enable default beam path loss for the PUCCH, determining the PL-RS of the PUCCH as the target PL-RS includes:

[0184] If the configuration information does not include a PL-RS sequence, the PUCCH resource of the PUCCH is not activated or does not indicate spatial relationship information, and the PUCCH resource is not activated or does not indicate a set of power control parameters, but the configuration information includes an indication to enable default beam path loss for the PUCCH, then the PL-RS of the PUCCH is determined to be the target PL-RS.

[0185] In this embodiment, it is possible to determine the PL-RS of the PUCCH as the target PL-RS even when there is no configured path loss reference signal sequence, no configured or activated spatial relationship information, no configured or activated power control parameter set, and the default beam path loss is enabled for the PUCCH. This can reduce configuration overhead.

[0186] Optionally, the terminal determines the power control parameters of the PUCCH, including at least one of the following:

[0187] When the PUCCH resource is activated or spatial relationship information is indicated, the closed-loop power control adjustment state of the PUCCH is determined to be the closed-loop power control adjustment state associated with the spatial relationship information.

[0188] If the PUCCH resource of the PUCCH is not activated or does not indicate spatial relationship information, but is activated or indicates a set of power control parameters, the closed-loop power control adjustment state of the PUCCH is determined to be the closed-loop power control adjustment state associated with the set of power control parameters.

[0189] If the PUCCH resource is not activated or does not indicate spatial relationship information, and if the power control parameter set is not activated or indicated, the closed-loop power control adjustment state of the PUCCH is determined to be the first preset value in the target received power set.

[0190] When the above-mentioned PUCCH resources are activated or there are N spatial relationship information, the closed-loop power control adjustment state corresponding to the PUCCH transmission of each spatial relationship information is the closed-loop power control adjustment state associated with it.

[0191] The closed-loop power control adjustment state associated with the aforementioned spatial relationship information can be the closed-loop power control adjustment state of the TRP / beam corresponding to the spatial relationship information. Alternatively, the closed-loop power control adjustment state associated with the spatial relationship information can be the closed-loop power control adjustment state indicated by the spatial relationship information.

[0192] When the aforementioned PUCCH resource is activated or indicates N power control parameter sets, the closed-loop power control adjustment state corresponding to the PUCCH transmission for each power control parameter set is its respective associated closed-loop power control adjustment state. The closed-loop power control adjustment state associated with the power control parameter set can be the closed-loop power control adjustment state explicitly or implicitly indicated by the power control parameter set.

[0193] The aforementioned target received power set can be pre-configured, and the aforementioned first preset value can be 0 or other values. There are no limitations on this, and it can be set according to the actual situation.

[0194] In this implementation, if the PUCCH resource activates spatial relationship information, the closed-loop power control adjustment state associated with the spatial relationship information is adopted; if the spatial relationship information is not activated, but the power control parameter set is activated, the closed-loop power control adjustment state associated with the power control parameter set is adopted; otherwise, the first preset value in the target received power set is adopted, so as to flexibly determine the closed-loop power control adjustment state according to the situation of the PUCCH resource.

[0195] In this embodiment, the terminal receives configuration information sent by the network-side device; based on the configuration information, the terminal selects a target transmission mode for transmitting the Physical Uplink Control Channel (PUCCH) from among multiple transmission modes; wherein, the transmission mode among the multiple transmission modes satisfies at least one of the following: the PUCCH is associated with spatial relationship information; the PUCCH is associated with a power control parameter set.
