[0051] The embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which like numerals indicate like elements throughout the several figures. The embodiments described below are exemplary and are intended to be illustrative of the present application, and are not to be understood as limiting of the present application.

[0052] This application addresses the problem in related technologies where repeated transmission of PUCCH resources can only support one PUCCH resource, and the number of transmissions needs to be configured according to the PUCCH format, resulting in all PUCCH resources corresponding to the same PUCCH format having the same configuration of the number of transmissions, making resource configuration inflexible. This application proposes a method for indicating the number of PUCCH transmissions.

[0053] The PUCCH transmission count indication method provided in this application determines multiple PUCCH resources indicated by the UE that support joint repeated transmission to multiple TRPs of the base station, identifies a target PUCCH resource from among the multiple PUCCH resources, and then determines the transmission count corresponding to the transmission timing of the PUCCH channel for joint repeated transmission of the target PUCCH resource based on the received indication signaling from the base station. Thus, by flexibly setting the transmission count of repeated PUCCH resource transmissions through the indication signaling from the base station, the flexibility of resource configuration is improved, and dynamic resource scheduling is achieved.

[0054] The following description, with reference to the accompanying drawings, details the method for indicating the number of PUCCH transmissions, the method for repeated transmissions, the apparatus, the UE, the base station, the storage medium, the computer program product, and the computer program provided in this application.

[0055] Figure 1 This is a flowchart illustrating a method for indicating the number of PUCCH transmissions provided in an embodiment of this application, applied to a UE.

[0056] like Figure 1 As shown, the method for indicating the number of PUCCH transmissions includes the following steps:

[0057] Step 101: Identify the multiple PUCCH resources indicated by the UE that support joint repeated transmission of multiple TRPs to the base station.

[0058] In all embodiments of this application, the method can also be applied to a technical solution involving joint transmission of multiple antenna panels. That is, step 101 is: determining multiple PUCCH resources indicated by the UE that support joint repeated transmission of multiple antenna panels to the base station.

[0059] In this embodiment, the base station may include multiple TRPs to utilize the cooperation between the multiple TRPs to transmit or receive data from multiple beams at multiple angles, thereby better overcoming various obstruction and blocking effects and ensuring the robustness of the link connection. Therefore, the UE can determine the number of TRPs in the base station based on the network configuration on the base station side, and determine the multiple PUCCH resources indicated by the UE to support joint repeated transmission to multiple TRPs of the base station.

[0060] Step 102, determining a PUCCH target resource from the plurality of PUCCH resources.

[0061] The PUCCH target resource can be a PUCCH resource that currently needs to be repeatedly transmitted.

[0062] The PUCCH target resource is one, and the PUCCH target resource corresponds to at least one beam supporting joint repetition transmission of multiple TRPs of the base station.

[0063] As a possible implementation, the PUCCH target resource can be configured by the base station. That is, in a possible implementation of the embodiment of the present application, the above step 102 can include:

[0064] Obtaining a downlink control information (DCI);

[0065] Determining the PUCCH target resource according to a field of PUCCH resource indication information contained in the DCI.

[0066] In the embodiment of the present application, the base station can configure the PUCCH target resource that needs to be repeatedly transmitted through the DCI, and indicate the PUCCH target resource through the field of PUCCH resource indication information contained in the DCI. Thus, the UE can determine the PUCCH resource corresponding to the value of the field of PUCCH resource indication information contained in the DCI as the PUCCH target resource when obtaining the DCI sent by the base station.

[0067] Step 103, receiving the indication signaling of the base station, and determining the transmission times corresponding to the transmission occasions of the PUCCH channel used for joint repetition transmission of the PUCCH target resource according to the indication signaling.

[0068] The indication signaling of the base station can be a radio resource control (RRC) signaling, and correspondingly, the RRC signaling can include the corresponding transmission times configured for the PUCCH target resource.

[0069] As a possible implementation, the base station can flexibly and dynamically configure the transmission times of the repetition transmission of the PUCCH target resource through the RRC signaling, so the UE can analyze and process the RRC signaling to determine the transmission times of the repetition transmission of the PUCCH target resource configured in the RRC signaling when receiving the RRC signaling of the base station.

[0070] Further, in response to the PUCCH target resource being one and the PUCCH target resource corresponding to at least one beam direction, the base station can configure a candidate set of transmission times for the PDCCH resource or the PDCCH format, so as to activate a responding transmission time from the candidate set of transmission times as the transmission time of the PDCCH target resource when repeated transmission of the PDCCH resource is required. That is, in a possible implementation manner of the embodiment of the present application, the step 103 can include:

[0071] obtaining, from RRC configuration information of the base station, a candidate set of transmission times respectively configured for a plurality of PUCCH resource optional sets or a plurality of PUCCH formats;

[0072] receiving a medium access control control element (MAC CE) of the base station, and determining, according to the MAC CE, an activated transmission time or a combination of transmission times configured for one PUCCH resource set or one PUCCH format from the candidate set of transmission times;

[0073] wherein the activated transmission time or the combination of transmission times is an activated transmission time or a combination of transmission times supporting PUCCH joint repeated transmission of the base station facing multiple TRPs.

[0074] As a possible implementation manner, the base station can configure a candidate set of transmission times according to the type of the PDCCH resource or the PDCCH format included in the PDCCH resource optional set through RRC signaling. Wherein, the candidate set of transmission times can include a plurality of transmission time values (such as {k1, k2, …, kn}). When repeated transmission of the PDCCH resource is required, the base station can activate one or more transmission times from the candidate set of transmission times for one PUCCH resource set or one PUCCH format through the MAC CE, so as to generate an activated transmission time or a combination of transmission times. And the activated transmission time or the combination of transmission times configured for one PUCCH resource set or one PUCCH format can be used for PUCCH joint repeated transmission of the base station facing multiple TRPs.

[0075] It should be noted that, in response to the PUCCH target resource corresponding to one beam direction, one transmission number can be activated, that is, one activated transmission number is generated for one PUCCH resource set or one PUCCH format, so as to perform repeated transmission through one beam direction corresponding to the PUCCH target resource according to the activated transmission number; and in response to the PUCCH target resource corresponding to multiple beam directions, the transmission number of the PDCCH resource repeated transmission for each beam direction can be uniformly configured or independently configured according to the number of beam directions.

[0076] As a possible implementation manner, in response to the beam direction being multiple, the base station can uniformly configure the transmission number of the PDCCH target resource repeated transmission for each beam direction through the MAC CE. That is, in a possible implementation manner of the embodiment of the present application, the activated transmission number corresponding to the PUCCH resource in the alternative set of transmission numbers is the first transmission number, and the transmission number of the activated PUCCH resource on each beam is determined according to the first transmission number in a preset manner.

[0077] For example, in response to the beam direction being two and the preset manner being "the transmission number of the activated PUCCH resource on each beam is the ratio of the first transmission number to the number of beam directions", the base station can configure the first transmission number as km from the alternative set of transmission numbers while activating the two beam directions through the MAC CE, and then it can be determined that the transmission number of the activated PUCCH resource on one beam can be k1=floor(km / 2), and the transmission number of the activated PUCCH resource on the other beam can be k2=km-k1.

[0078] As another possible implementation manner, in response to the beam direction being multiple, the base station can independently configure the transmission number of the PDCCH target resource repeated transmission for each beam direction through the MAC CE. That is, in a possible implementation manner of the embodiment of the present application, the activated transmission number or the combination of transmission numbers includes multiple second transmission numbers, each of which corresponds to the transmission number on the transmission occasion of the PUCCH resource mapped by one beam direction.

[0079] For example, in response to the beam direction being two, the base station can configure two second transmission numbers as k1 and k2 from the alternative set of transmission numbers while activating the two beam directions through the MAC CE, and the second transmission number k1 corresponds to the transmission number on the transmission occasion of the PUCCH resource mapped by one beam direction, and the second transmission number k2 corresponds to the transmission number on the transmission occasion of the PUCCH resource mapped by the other beam direction. That is, the total transmission number K_total=k1+k2.

[0080] The PUCCH transmission number indication method provided by the embodiments of the present application determines multiple PUCCH resources indicated for the UE to support joint repetition transmission of multiple TRPs of a base station, determines a PUCCH target resource from the multiple PUCCH resources, and then determines, according to received indication signaling of the base station, a transmission number corresponding to a transmission occasion of a PUCCH channel of the PUCCH target resource for joint repetition transmission. In this way, the transmission number of PUCCH resource repetition transmission is flexibly set through the indication signaling of the base station, thereby improving the flexibility of resource configuration and achieving dynamic scheduling of resources.

[0081] The embodiments of the present application will be further described below. Figure 2 Another PUCCH transmission number indication method provided by the embodiments of the present application will be further described.

[0082] Figure 2 The flowchart of another PUCCH transmission number indication method provided by the embodiments of the present application is applied to a UE.

[0083] As shown in the PUCCH transmission number indication method, the method comprises the following steps: Figure 2

[0084] Step 201, determining multiple PUCCH resources indicated for the UE to support joint repetition transmission of multiple TRPs of a base station.

[0085] In all embodiments of the present application, the method can also be applied to a technical solution of joint transmission of multiple antenna panels.That is, step 201 is: determining multiple PUCCH resources indicated for the UE to support joint repetition transmission of multiple antenna panels of a base station.

[0086] Step 202, determining a PUCCH target resource from the multiple PUCCH resources.

[0087] In the embodiments of the present application, steps 201-202 can be implemented in any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described again.

[0088] Step 203, receiving indication signaling of the base station, and determining, according to the indication signaling, a transmission number corresponding to a transmission occasion of a PUCCH channel of the PUCCH target resource for joint repetition transmission, wherein the PUCCH target resource is multiple.

[0089] As one possible implementation, in response to the presence of multiple PUCCH target resources, the base station can configure the transmission count of the multiple PUCCH target resources via RRC signaling according to the format of each resource. That is, in one possible implementation of this application embodiment, the aforementioned indication signaling can be RRC signaling, wherein when the transmission formats of the multiple PUCCH target resources are the same, the RRC signaling includes a third transmission count, wherein the third transmission count is used to indicate the transmission count of the multiple PUCCH target resources.

[0090] In this embodiment, in response to multiple PUCCH target resources having the same transmission format, the base station can configure a third transmission count for multiple PUCCH target resources in the RRC signaling according to the transmission format of the PUCCH target resources. That is, the transmission count for each PUCCH target resource is configured as the third transmission count. Therefore, in response to multiple PUCCH target resources having the same transmission format, the UE can determine the third transmission count contained in the RRC instruction when receiving the RRC instruction sent by the base station, and determine the transmission count for each PUCCH target resource as the third transmission count. For example, if the number of PUCCH target resources is 2, the third transmission count is k, and the total number of transmissions is K_total = 2 × k.

[0091] Accordingly, when the transmission formats of multiple PUCCH target resources are different, the base station can configure different transmission counts for each PUCCH target resource according to the transmission format of each PUCCH target resource. That is, in one possible implementation of the embodiments of this application, the above-mentioned indication signaling can be RRC signaling, wherein when the transmission formats of multiple PUCCH target resources are different, the RRC signaling includes multiple fourth transmission counts corresponding to the multiple PUCCH target resources respectively.

[0092] In this embodiment, in response to the different transmission formats of multiple PUCCH target resources, the base station can configure a fourth transmission count for each PUCCH target resource in the RRC signaling according to the transmission format of each PUCCH target resource. That is, the fourth transmission count for each PUCCH target resource can be different. Therefore, in response to the different transmission formats of multiple PUCCH target resources, the UE can determine each fourth transmission count contained in the RRC instruction when receiving the RRC instruction sent by the base station, and determine each fourth transmission count as the transmission count for the corresponding PUCCH target resource. For example, if the number of PUCCH target resources is 2, the two third transmission counts are k1 and k2, and the total transmission count is K_total = k1 + k2.

[0093] As a possible implementation, in response to the PUCCH target resource being multiple, the base station can further be configured by RRC signaling to configure different transmission times for the multiple PUCCH target resources respectively. That is, in a possible implementation of the embodiment of the present application, the indication signaling is RRC signaling, wherein the RRC signaling includes a corresponding fifth transmission time configured for each PUCCH resource in the multiple PUCCH target resources.

[0094] In the embodiment of the present application, in response to the number of PUCCH target resources being multiple, the base station can further configure different transmission times for each PUCCH target resource respectively. Thus, in response to the PUCCH target resource being multiple, the UE can determine the respective fifth transmission times contained in the RRC instruction received from the base station, and determine the respective fifth transmission times as the transmission times of the corresponding PUCCH target resources respectively. For example, the number of PUCCH target resources is 2, and the two fifth transmission times are k1 and k2 respectively, and the total transmission time is K_total = k1 + k2.

[0095] Further, in response to the PUCCH target resource being multiple, the base station can configure a candidate set of transmission times for the PDCCH resource or PDCCH format, so as to activate the corresponding transmission time from the candidate set of transmission times as the transmission time of the PDCCH target resource when it is necessary to perform repeated transmission on the PDCCH resource. That is, in a possible implementation of the embodiment of the present application, the above step 203 can include:

[0096] obtaining a plurality of PUCCH resource optional sets or a candidate set of transmission times configured for a plurality of PUCCH formats from the RRC configuration information of the base station;

[0097] receiving the MAC CE of the base station, and determining the activated transmission time or the combination of transmission times configured for at least one PUCCH resource set or at least one PUCCH format from the candidate set of transmission times according to the MAC CE, wherein the activated transmission time or the combination of transmission times is: the activated transmission time or the combination of transmission times supporting the PUCCH joint repeated transmission of multiple TRPs of the base station.

[0098] As a possible implementation manner, the base station can configure a candidate set of transmission times for the multiple PDCCH resource optional sets or the multiple PDCCHs according to the types of PDCCH resources or the multiple PDCCH formats included in the multiple PDCCH resource optional sets respectively through RRC signaling. The candidate set of transmission times can include multiple values of transmission times (such as {k1, k2, …, kn}). When the multiple PDCCH resources need to be repeatedly transmitted, the base station can activate one or more transmission times from the corresponding candidate set of transmission times for the multiple PUCCH resource sets or the multiple PUCCH formats through a MAC CE to generate an activated transmission time or a combination of transmission times. The activated transmission time or the combination of transmission times configured for at least one PUCCH resource set or at least one PUCCH format can be used for the PUCCH joint repeated transmission of the multiple PUCCH target resources to multiple TRPs of the base station.

[0099] It should be noted that, in response to the PUCCH target resource being multiple and the PUCCH target resource corresponding to one beam direction, for each PUCCH target resource, one transmission time can be activated, that is, one activated transmission time is generated for one PUCCH resource set or one PUCCH format, so as to perform repeated transmission through the one beam direction corresponding to the PUCCH target resource according to the activated transmission time; in response to the PUCCH target resource corresponding to multiple beam directions, for each PDCCH target resource, the number of beam directions can be used to uniformly configure or independently configure the transmission times of the PDCCH target resource repeatedly transmitted by each beam direction.

[0100] As a possible implementation manner, in response to the beam direction being multiple, for each PDCCH target resource, the base station can uniformly configure the transmission times of the PDCCH target resource repeatedly transmitted by each beam direction through a MAC CE. That is, in a possible implementation manner of the embodiment of the present application, the activated transmission time of the PUCCH resource in the candidate set of transmission times is a first transmission time, and the transmission times of the PUCCH resource activated on each beam are determined according to the first transmission time in a preset manner.

[0101] For example, for a PUCCH target resource A, in response to the beam direction being two, the preset manner is "the transmission times of the PUCCH resource activated on each beam direction is the ratio of the first transmission times and the number of beam directions", the base station can configure the first transmission times as km from the candidate set of transmission times corresponding to the PUCCH target resource A while activating the two beam directions through the MAC CE, and then it can be determined that the transmission times of the PUCCH target resource A activated on one beam direction is k1 = floor(km / 2), and the transmission times of the PUCCH resource activated on the other beam direction is k2 = km-k1.

[0102] As another possible implementation, in response to the beam direction being multiple, for each PDCCH target resource, the base station can independently configure the transmission times of the PDCCH target resource for repeated transmission on each beam direction through the MAC CE. That is, in a possible implementation of the embodiment of the present application, the activated transmission times or the combination of transmission times include multiple second transmission times, and each second transmission time indicates the transmission times on the transmission occasion corresponding to one PUCCH resource.

[0103] For example, for a PUCCH target resource A, in response to the beam direction being two, the base station can configure two second transmission times as k1 and k2 from the candidate set of transmission times corresponding to the PUCCH target resource A while activating the two beam directions through the MAC CE, and the second transmission time k1 corresponds to the transmission times on the transmission occasion of the PUCCH target resource A mapped by one beam direction, and the second transmission time k2 corresponds to the transmission times on the transmission occasion of the PUCCH target resource A mapped by the other beam direction. That is, the total transmission times K_total = k1+k2.

[0104] As a possible implementation, the base station can also configure the association relationship table between the code points of the PUCCH resource information and the PUCCH target resources through the RRC signaling to configure the corresponding relationship between the PUCCH resource and the transmission times through the association relationship table. That is, in a possible implementation of the embodiment of the present application, the indication signaling is the RRC signaling, wherein the RRC instruction includes the association relationship table between the code points of the PUCCH resource information and the PUCCH target resources, and the association relationship table includes the PUCCH repeated transmission or the transmission times corresponding to the PUCCH target resource.

[0105] Optionally, in response to the transmission number corresponding to the PUCCH repetition transmission being included in the association table, the transmission number corresponding to each PUCCH target resource can be allocated according to the number of PUCCH target resources and the transmission number corresponding to the PUCCH repetition transmission in a preset manner. For example, the transmission number corresponding to the PUCCH repetition transmission is k, the number of PUCCH target resources is 2, and the preset manner is "allocate the transmission number to each PUCCH target resource equally", then the transmission number of each PUCCH target resource can be determined as k / 2.

[0106] Optionally, in response to the transmission number corresponding to the PUCCH target resource being included in the association table, the transmission number corresponding to each PUCCH target resource can be determined according to the code point corresponding to the PUCCH target resource.

[0107] Further, the base station can configure the code point of the PUCCH resource information through the DCI. That is, in one possible implementation manner of the embodiment of the application, the step 203 can include:

[0108] receiving the DCI;

[0109] querying the association table according to the field containing the PUCCH resource information corresponding to the DCI to determine the transmission number.

[0110] In the embodiment of the application, the base station can configure the corresponding code point of the PDCCH target resource through the DCI, so that after the UE obtains the DCI sent by the base station, the code point of the PUCCH target resource can be determined according to the field containing the PUCCH resource information in the DCI, then the association table is queried according to the code point of the PUCCH target resource, and the transmission number corresponding to the code point of the PUCCH target resource is determined as the transmission number corresponding to the PUCCH target resource.

[0111] Optionally, the total transmission number corresponding to the PUCCH target resource can also be included in the association table, that is, one DCI code point can correspond to one total transmission number. Thus, after the UE obtains the DCI sent by the base station, the code point corresponding to the total transmission number can be determined according to the field containing the PUCCH resource information in the DCI, then the association table is queried according to the code point corresponding to the total transmission number to determine the total transmission number corresponding to the PUCCH target resource. Further, the transmission number corresponding to each PUCCH target resource can be allocated according to the number of PUCCH target resources and the total transmission number. For example, the total transmission number is k, the number of PUCCH target resources is 2, then the transmission number corresponding to one PUCCH target resource can be k1=floor(k / 2), and the transmission number corresponding to the other PUCCH target resource can be k2=k-k1.

[0112] The PUCCH transmission count indication method provided in this application determines multiple PUCCH resources indicated by the UE that support joint repeated transmission to multiple TRPs of the base station, identifies a target PUCCH resource from among the multiple PUCCH resources, and then determines the transmission count corresponding to the transmission timing of the multiple target PUCCH resources for joint repeated transmission of the PUCCH channel based on the received indication signaling from the base station. Thus, by flexibly setting the transmission count of repeated PUCCH resource transmissions through the indication signaling from the base station, the flexibility of resource configuration is improved, and dynamic resource scheduling is achieved.

[0113] The following is combined Figure 3 The present application provides a method for repeated transmission.

[0114] Figure 3 This is a flowchart illustrating a method for repeated transmission provided in an embodiment of this application, applied to a UE.

[0115] like Figure 3 As shown, the method for repeated transmission includes the following steps:

[0116] Step 301: Identify the multiple PUCCH resources indicated by the UE that support joint repeated transmission of multiple TRPs to the base station.

[0117] In all embodiments of this application, the method can also be applied to a technical solution involving joint transmission of multiple antenna panels. That is, step 301 is: determining multiple PUCCH resources indicated by the UE that support joint repeated transmission of multiple antenna panels to the base station.

[0118] Step 302: Determine the target PUCCH resource from multiple PUCCH resources.

[0119] In the embodiments of this application, steps 301-302 can be implemented in any of the embodiments of this application. The embodiments of this application do not limit this and will not be described in detail.

[0120] Step 303: Determine the number of transmissions.

[0121] As one possible implementation, the number of times the PUCCH target resource is transmitted can be determined according to the PUCCH transmission number indication method described in any of the foregoing embodiments. The specific implementation process and principle can be referred to the detailed description of the foregoing embodiments, and will not be repeated here.

[0122] As another possible implementation, the number of times the PUCCH target resource is transmitted can be determined between the base station and the UE according to the protocol; or, the number of times the PUCCH target resource is transmitted can be determined according to the number of frequency hopping within the time slot.

[0123] Step 304: Repeat the transmission based on the number of transmissions.

[0124] In this embodiment of the application, after determining the number of times the PUCCH target resource will be transmitted, the PUCCH target resource can be repeatedly transmitted at the corresponding time through the corresponding TRP according to the number of transmissions.

[0125] The PUCCH transmission count indication method provided in this application determines multiple PUCCH resources that support joint repeated transmission to multiple TRPs of the base station, as indicated by the UE, and identifies the target PUCCH resource from among the multiple PUCCH resources. It then determines the transmission count and performs repeated transmission based on the transmission count. Therefore, by using the base station's indication signaling, the transmission count of repeated PUCCH resource transmissions can be flexibly set, thereby improving the flexibility of resource configuration and realizing dynamic resource scheduling.

[0126] The following is combined Figure 4 The present application provides a further explanation of another method for indicating the number of PUCCH transmissions.

[0127] The figure is a flowchart illustrating another method for indicating the number of PUCCH transmissions provided in this application embodiment, applied to a base station.

[0128] like Figure 4 As shown, the method for indicating the number of PUCCH transmissions includes the following steps:

[0129] Step 401: Send an indication signaling message to the UE, wherein the indication signaling message is used to indicate the number of transmissions corresponding to the transmission timing of the PUCCH channel for joint repeated transmission of the PUCCH target resource.

[0130] In all embodiments of this application, the method can also be applied to technical solutions involving joint transmission of multiple antenna panels.

[0131] The PUCCH target resource can be a PUCCH resource that needs to be transmitted repeatedly.

[0132] There is one PUCCH target resource, and the PUCCH target resource corresponds to at least one beam that supports joint repeated transmission of multiple TRPs to the base station.

[0133] As a possible implementation manner, the PUCCH target resource can be configured by the base station. That is, in a possible implementation manner of the embodiment of the present application, the step 401 can include:

[0134] sending the DCI to the UE, so that the UE determines the PUCCH target resource according to the field of the PUCCH resource indication information contained in the DCI.

[0135] In the embodiment of the present application, the base station can configure the PUCCH target resource that needs to be repeatedly transmitted through the DCI, and indicate the PUCCH target resource through the field of the PUCCH resource indication information contained in the DCI. Thus, the base station can send the DCI to the UE, so that the UE can determine the PUCCH target resource corresponding to the value of the field of the PUCCH resource indication information contained in the DCI when obtaining the DCI sent by the base station.

[0136] Among them, the indication signaling of the base station can be RRC signaling; correspondingly, the RRC signaling can include the corresponding transmission times configured for the PUCCH target resource.

[0137] As a possible implementation manner, the base station can flexibly and dynamically configure the transmission times of the repeated transmission of the PUCCH target resource through the RRC signaling, and send it to the UE, so that the UE can analyze and process the RRC signaling when receiving the RRC signaling of the base station, to determine the transmission times of the repeated transmission of the PUCCH target resource configured in the RRC signaling.

[0138] Further, in response to the PUCCH target resource being one and the PUCCH target resource corresponding to at least one beam direction, the base station can configure a candidate set of transmission times for the PDCCH resource or the PDCCH format, so as to activate the corresponding transmission times from the candidate set of transmission times as the transmission times of the PDCCH target resource when the PDCCH resource needs to be repeatedly transmitted. That is, in a possible implementation manner of the embodiment of the present application, the step 401 can include:

[0139] sending the RRC configuration information of the base station to the UE, wherein the RRC configuration information includes the candidate set of transmission times respectively configured for the multiple PUCCH resource optional sets or the multiple PUCCH formats;

[0140] sending the MAC CE of the base station to the UE, and configuring the activated transmission times or the combination of transmission times for one PUCCH resource set or one PUCCH format according to the candidate set of transmission times in the MAC CE;

[0141] The activated transmission number or the combination of transmission numbers is: an activated transmission number or a combination of transmission numbers supporting PUCCH joint repetition transmission of multiple TRPs of a base station.

[0142] As a possible implementation, the base station can configure a candidate set of transmission numbers through RRC signaling according to the type or PDCCH format of the PDCCH resource included in the optional set of PDCCH resources. The candidate set of transmission numbers can include multiple values of transmission numbers (such as {k1, k2, …, kn}). When repetition transmission of the PDCCH resource is needed, the base station can activate one or more transmission numbers from the candidate set of transmission numbers for a PUCCH resource set or a PUCCH format through a MAC CE to generate an activated transmission number or a combination of transmission numbers. The activated transmission number or the combination of transmission numbers configured for a PUCCH resource set or a PUCCH format can be used for PUCCH joint repetition transmission of multiple TRPs of a base station for a PUCCH target resource.

[0143] It should be noted that in response to the PUCCH target resource corresponding to one beam direction, one transmission number can be activated, that is, one activated transmission number is generated for a PUCCH resource set or a PUCCH format to perform repetition transmission through one beam direction corresponding to the PUCCH target resource according to the activated transmission number; in response to the PUCCH target resource corresponding to multiple beam directions, the transmission number of the PDCCH target resource for repetition transmission can be uniformly configured or independently configured for each beam direction according to the number of beam directions.

[0144] As a possible implementation, in response to the beam direction being multiple, the base station can uniformly configure the transmission number of the PDCCH target resource for repetition transmission for each beam direction through a MAC CE. That is, in a possible implementation of the embodiment of the present application, the activated transmission number of the PUCCH resource in the candidate set of transmission numbers is a first transmission number, and the transmission number of the activated PUCCH resource on each beam is determined according to the first transmission number in a preset manner.

[0145] For example, in response to the beam direction being two and the preset manner being “the transmission number of the activated PUCCH resource on each beam is the ratio of the first transmission number to the number of beam directions”, the base station can configure the first transmission number km from the candidate set of transmission numbers while activating the two beam directions through a MAC CE, and then the transmission number of the activated PUCCH resource on each beam can be determined as k1 = floor(km / 2), and the other resource can be k2 = km-k1.

[0146] As another possible implementation, in response to the number of beam directions being multiple, the base station can configure the number of repetitions of the transmission of each beam direction PDCCH target resource independently by MAC CE. That is, in a possible implementation of the embodiment of the present application, the activated number of repetitions or the combination of the number of repetitions includes multiple second numbers of repetitions, each of which corresponds to the number of repetitions on the transmission occasion of the PUCCH resource mapped by one beam direction.

[0147] For example, in response to the number of beam directions being two, the base station can configure two second numbers of repetitions k1 and k2 from the candidate set of numbers of repetitions while activating the two beam directions by MAC CE, and the second number of repetitions k1 corresponds to the number of repetitions on the transmission occasion of the PUCCH resource mapped by one beam direction, and the second number of repetitions k2 corresponds to the number of repetitions on the transmission occasion of the PUCCH resource mapped by the other beam direction. That is, the total number of repetitions K_total = k1 + k2.

[0148] The PUCCH transmission number indication method provided by the embodiment of the present application sends indication signaling to the UE by the base station, wherein the indication signaling is used to indicate the number of repetitions of the transmission occasion of the PUCCH channel of the PUCCH target resource used for joint repetition transmission. Therefore, through the indication signaling of the base station, the number of repetitions of the PUCCH resource repetition transmission is flexibly set, thereby improving the flexibility of resource configuration and realizing dynamic scheduling of resources.

[0149] The PUCCH transmission number indication method provided by the embodiment of the present application will be further described below. Figure 5 The PUCCH transmission number indication method provided by the embodiment of the present application will be further described below.

[0150] Figure 5 The flowchart of another PUCCH transmission number indication method provided by the embodiment of the present application is applied to a base station.

[0151] As Figure 5 indicated, the PUCCH transmission number indication method includes the following steps:

[0152] Step 501, send indication signaling to the UE, wherein the indication signaling is used to indicate the number of repetitions of the transmission occasion of the PUCCH channel of the PUCCH target resource used for joint repetition transmission, and the PUCCH target resource is multiple.

[0153] In all embodiments of the present application, the method can also be applied to the technical solution of multiple antenna panels panel joint transmission.

[0154] As a possible implementation, in response to the PUCCH target resource being multiple, the base station can configure the number of transmissions of the multiple PUCCH target resources according to the format of each resource in the PUCCH target resource through RRC signaling. That is, in a possible implementation of the embodiment of the present application, the indication signaling can be RRC signaling, wherein when the transmission formats of the multiple PUCCH target resources are the same, the RRC signaling includes a third number of transmissions, wherein the third number of transmissions is used to indicate the number of transmissions of the multiple PUCCH target resources.

[0155] In the embodiment of the present application, in response to the transmission formats of the multiple PUCCH target resources being the same, the base station can configure a third number of transmissions for the multiple PUCCH target resources in the RRC signaling according to the transmission format of the PUCCH target resource, that is, the number of transmissions of each PUCCH target resource is configured as the third number of transmissions. Therefore, in response to the transmission formats of the multiple PUCCH target resources being the same, the base station can send RRC signaling to the UE, so that the UE can determine the third number of transmissions contained in the RRC instruction when receiving the RRC instruction sent by the base station, and determine the number of transmissions of each PUCCH target resource as the third number of transmissions. For example, the number of PUCCH target resources is 2, the third number of transmissions is k, and the total number of transmissions is K_total = 2 x k.

[0156] Correspondingly, in response to the transmission formats of the multiple PUCCH target resources being different, the base station can configure different numbers of transmissions for each PUCCH target resource according to the transmission format of each PUCCH target resource. That is, in a possible implementation of the embodiment of the present application, the indication signaling can be RRC signaling, wherein when the transmission formats of the multiple PUCCH target resources are different, the RRC signaling includes multiple fourth numbers of transmissions corresponding to the multiple PUCCH target resources respectively.

[0157] In the embodiment of the present application, in response to the transmission formats of the multiple PUCCH target resources being different, the base station can configure a fourth number of transmissions for the multiple PUCCH target resources in the RRC signaling according to the transmission format of each PUCCH target resource, that is, the fourth numbers of transmissions of each PUCCH target resource can be different. Therefore, in response to the transmission formats of the multiple PUCCH target resources being different, the base station can send RRC signaling to the UE, so that the UE can determine each fourth number of transmissions contained in the RRC instruction when receiving the RRC instruction sent by the base station, and determine each fourth number of transmissions as the number of transmissions of the corresponding PUCCH target resource respectively. For example, the number of PUCCH target resources is 2, the two third numbers of transmissions are k1 and k2 respectively, and the total number of transmissions is K_total = k1 + k2.

[0158] As a possible implementation, in response to the PUCCH target resource being multiple, the base station can further be configured by RRC signaling to configure different transmission times for the multiple PUCCH target resources respectively. That is, in a possible implementation of the embodiment of the present application, the indication signaling is RRC signaling, wherein the RRC signaling includes a corresponding fifth transmission time configured for each PUCCH resource in the multiple PUCCH target resources.

[0159] In the embodiment of the present application, in response to the number of PUCCH target resources being multiple, the base station can further configure different transmission times for each PUCCH target resource respectively. Thus, in response to the PUCCH target resource being multiple, the base station can send RRC signaling to the UE, so that the UE can determine the respective fifth transmission times contained in the RRC instruction received by the base station when receiving the RRC instruction sent by the base station, and determine the respective fifth transmission times as the transmission times of the corresponding PUCCH target resources respectively. For example, the number of PUCCH target resources is 2, and the two fifth transmission times are k1 and k2 respectively, and the total transmission time is K_total = k1 + k2.

[0160] Further, in response to the PUCCH target resource being multiple, the base station can configure a candidate set of transmission times for the PDCCH resource or the PDCCH format, so as to activate the corresponding transmission time from the candidate set of transmission times as the transmission time of the PDCCH target resource when it is necessary to perform repeated transmission on the PDCCH resource. That is, in a possible implementation of the embodiment of the present application, the above step 501 can include:

[0161] sending the RRC configuration information of the base station to the UE, wherein the RRC configuration information includes a candidate set of transmission times configured for the multiple PUCCH resource optional set or the multiple PUCCH format respectively;

[0162] sending the MAC CE of the base station to the UE, and configuring the activated transmission time or the combination of transmission times for one PUCCH resource set or one PUCCH format in the MAC CE according to the candidate set of transmission times;

[0163] wherein the activated transmission time or the combination of transmission times is an activated transmission time or a combination of transmission times supporting PUCCH joint repeated transmission of multiple TRPs of the base station.

[0164] As a possible implementation manner, the base station can configure a candidate set of transmission times for the multiple PDCCH resource optional sets or the multiple PDCCHs according to the types of PDCCH resources or the multiple PDCCH formats included in the multiple PDCCH resource optional sets respectively through RRC signaling. The candidate set of transmission times can include multiple values of transmission times (such as {k1, k2, …, kn}). When the multiple PDCCH resources need to be repeatedly transmitted, the base station can activate one or more transmission times from the corresponding candidate set of transmission times for the multiple PUCCH resource sets or the multiple PUCCH formats through a MAC CE to generate an activated transmission time or a combination of transmission times. The activated transmission time or the combination of transmission times configured for at least one PUCCH resource set or at least one PUCCH format can be used for the base station multiple-TRP-oriented PUCCH joint repeated transmission of the multiple PUCCH target resources.

[0165] It should be noted that, in response to the PUCCH target resource being multiple and the PUCCH target resource corresponding to one beam direction, for each PUCCH target resource, one transmission time can be activated, that is, one activated transmission time is generated for one PUCCH resource set or one PUCCH format, so as to perform repeated transmission through the one beam direction corresponding to the PUCCH target resource according to the activated transmission time; in response to the PUCCH target resource corresponding to multiple beam directions, for each PDCCH target resource, the number of beam directions can be used to uniformly configure or independently configure the transmission times of repeated transmission of the PDCCH target resource for each beam direction.

[0166] As a possible implementation manner, in response to the beam direction being multiple, for each PDCCH target resource, the base station can uniformly configure the transmission times of repeated transmission of the PDCCH target resource for each beam direction through a MAC CE. That is, in a possible implementation manner of the embodiment of the present application, the activated transmission time of the PUCCH resource in the candidate set of transmission times is a first transmission time, and the transmission times of the activated PUCCH resource on each beam are determined according to the first transmission time in a preset manner.

[0167] For example, for a PUCCH target resource A, in response to the beam direction being two, the preset manner is "the transmission times of the PUCCH resource activated on each beam direction is the ratio of the first transmission times and the number of beam directions", the base station can configure the first transmission times as km from the candidate set of transmission times corresponding to the PUCCH target resource A while activating the two beam directions through the MAC CE, and then it can be determined that the transmission times of the PUCCH target resource A activated on one beam direction is k1 = floor(km / 2), and the transmission times of the PUCCH resource activated on the other beam direction is k2 = km-k1.

[0168] As another possible implementation, in response to the beam direction being multiple, the base station can independently configure the transmission times of each beam direction PDCCH target resource through the MAC CE for each PDCCH target resource. That is, in a possible implementation of the embodiment of the present application, the activated transmission times or the combination of transmission times include multiple second transmission times, and each second transmission time indicates the transmission times on the transmission occasion corresponding to one PUCCH resource.

[0169] For example, for a PUCCH target resource A, in response to the beam direction being two, the base station can configure two second transmission times as k1 and k2 from the candidate set of transmission times corresponding to the PUCCH target resource A while activating the two beam directions through the MAC CE, and the second transmission time k1 corresponds to the transmission times on the transmission occasion of the PUCCH target resource A mapped by one beam direction, and the second transmission time k2 corresponds to the transmission times on the transmission occasion of the PUCCH target resource A mapped by the other beam direction. That is, the total transmission times K_total = k1+k2.

[0170] As a possible implementation, the base station can also configure the association relationship table between the code points of the PUCCH resource information and the PUCCH target resources through the RRC signaling to configure the corresponding relationship between the PUCCH resource and the transmission times through the association relationship table. That is, in a possible implementation of the embodiment of the present application, the indication signaling is the RRC signaling, wherein the RRC instruction includes the association relationship table between the code points of the PUCCH resource information and the PUCCH target resources, and the association relationship table includes the transmission times corresponding to the PUCCH repetition transmission or the PUCCH target resource.

[0171] Optionally, in response to the transmission number corresponding to the PUCCH repetition transmission being included in the association table, the transmission number corresponding to each PUCCH target resource can be allocated according to the number of PUCCH target resources and the transmission number corresponding to the PUCCH repetition transmission in a preset manner. For example, the transmission number corresponding to the PUCCH repetition transmission is k, the number of PUCCH target resources is 2, and the preset manner is "allocate the transmission number equally to each PUCCH target resource", then the transmission number of each PUCCH target resource can be determined as k / 2.

[0172] Optionally, in response to the transmission number corresponding to the PUCCH target resource being included in the association table, the base station can configure the code point of the PUCCH resource information through the DCI, so that the base station can determine the transmission number corresponding to each PUCCH target resource according to the code point corresponding to the PUCCH target resource. That is, in one possible implementation of the embodiment of the application, the above step 501 can include:

[0173] sending the DCI to the UE, wherein the DCI contains the field of the PUCCH resource information.

[0174] In the embodiment of the application, the base station can configure the code point corresponding to the PUCCH target resource through the DCI, and send the DCI to the UE, so that the UE can determine the code point of the PUCCH target resource according to the field of the PUCCH resource information contained in the DCI after obtaining the DCI sent by the base station, and then query the association table according to the code point of the PUCCH target resource, and determine the transmission number corresponding to the code point of the PUCCH target resource as the transmission number corresponding to the PUCCH target resource.

[0175] Optionally, the association table can also include the total transmission number corresponding to the PUCCH target resource, that is, one DCI code point can correspond to one total transmission number. Therefore, the base station can configure the code point value corresponding to the total transmission number through the DCI, and send the DCI to the UE, so that the UE can determine the code point corresponding to the total transmission number according to the field of the PUCCH resource information contained in the DCI after obtaining the DCI sent by the base station, and then query the association table according to the code point corresponding to the total transmission number, and determine the total transmission number corresponding to the PUCCH target resource. Further, according to the number of PUCCH target resources, the transmission number corresponding to each PUCCH target resource can be allocated according to the total transmission number. For example, the total transmission number is k, and the number of PUCCH target resources is 2, then the transmission number corresponding to one PUCCH target resource can be k1=floor(k / 2), and the transmission number corresponding to the other PUCCH target resource can be k2=k-k1.

[0176] The method for indicating the number of PUCCH transmissions provided in the embodiments of the present application comprises: a base station sending indication signaling to a UE, wherein the indication signaling is used to indicate the number of transmission occasions corresponding to the transmission of a PUCCH channel of a PUCCH target resource used for joint repeated transmission, and the PUCCH target resource is multiple. In this way, the number of transmission occasions of PUCCH resource repeated transmission is flexibly set through the indication signaling of the base station, thereby improving the flexibility of resource configuration and realizing dynamic scheduling of resources.

[0177] In order to realize the above-mentioned embodiments, the present application further provides a device for indicating the number of PUCCH transmissions.

[0182] A receiving module 62 is used to receive indication signaling of a base station and determine the number of transmission occasions corresponding to the transmission of a PUCCH channel of the PUCCH target resource used for joint repeated transmission according to the indication signaling.

[0183] In actual use, the device for indicating the number of PUCCH transmissions provided in the embodiments of the present application can be configured in any UE to execute the aforementioned method for indicating the number of PUCCH transmissions.

[0184] The device for indicating the number of PUCCH transmissions provided in the embodiments of the present application determines multiple PUCCH resources supporting joint repeated transmission of multiple TRPs of a base station indicated for the UE and determines the PUCCH target resource from the multiple PUCCH resources, and then determines the number of transmission occasions corresponding to the transmission of a PUCCH channel of the PUCCH target resource used for joint repeated transmission according to the received indication signaling of the base station. In this way, the number of transmission occasions of PUCCH resource repeated transmission is flexibly set through the indication signaling of the base station, thereby improving the flexibility of resource configuration and realizing dynamic scheduling of resources.

[0185] In a possible implementation form of the application, the PUCCH target resource is one, and the PUCCH target resource corresponds to at least one beam direction supporting joint transmission of the base station to multiple TRPs, the indication signaling is radio resource control (RRC) signaling, and the RRC signaling includes a corresponding number of transmissions configured for the PUCCH target resource.

[0186] Further, in another possible implementation form of the application, the determination module 61 is further configured to:

[0187] obtain downlink control information (DCI);

[0188] determine the PUCCH target resource according to a field of PUCCH resource indication information contained in the DCI.

[0189] Further, in another possible implementation form of the application, the PUCCH target resource is one, and the PUCCH target resource corresponds to at least one beam direction, and the receiving module 62 is specifically configured to:

[0190] obtain, from RRC configuration information of the base station, a candidate set of numbers of transmissions respectively configured for a plurality of PUCCH resource optional sets or a plurality of PUCCH formats;

[0191] receive a medium access control control element (MAC CE) of the base station, and determine, according to the MAC CE, an activated number of transmissions or a combination of numbers of transmissions configured for one PUCCH resource set or one PUCCH format from the candidate set of numbers of transmissions;

[0192] The activated number of transmissions or the combination of numbers of transmissions is an activated number of transmissions or a combination of numbers of transmissions supporting joint transmission of the base station to multiple TRPs.

[0193] Further, in another possible implementation form of the application, the activated number of transmissions or the combination of numbers of transmissions configured for one PUCCH resource set or one PUCCH format is used for joint transmission of the PUCCH target resource to multiple TRPs of the base station.

[0194] Further, in another possible implementation form of the application, the number of transmissions corresponding to the activated PUCCH resource in the candidate set of numbers of transmissions is a first number of transmissions, and the number of transmissions of the activated PUCCH resource on each beam is determined according to the first number of transmissions in a preset manner.

[0195] Further, in a possible implementation form of the application, the activated transmission number or the combination of transmission numbers comprises a plurality of second transmission numbers, each of which corresponds to a transmission number of a transmission occasion of a PUCCH resource mapped by a beam direction.

[0196] Further, in a possible implementation form of the application, the PUCCH target resource is a plurality of PUCCH target resources, and the indication signaling is RRC signaling, wherein,

[0197] When the transmission formats of the plurality of PUCCH target resources are the same, the RRC signaling comprises a third transmission number, wherein the third transmission number is used to indicate the transmission number of the plurality of PUCCH target resources.

[0198] Further, in a possible implementation form of the application, when the transmission formats of the plurality of PUCCH target resources are different, the RRC signaling comprises a plurality of fourth transmission numbers respectively corresponding to the plurality of PUCCH target resources.

[0199] Further, in a possible implementation form of the application, the PUCCH target resource is a plurality of PUCCH target resources, and the indication signaling is RRC signaling, wherein the RRC signaling comprises a corresponding fifth transmission number configured for each PUCCH target resource of the plurality of PUCCH target resources.

[0200] Further, in a possible implementation form of the application, the PUCCH target resource is a plurality of PUCCH target resources, and the receiving module 62 is further configured to:

[0203] Further, in a possible implementation form of the application, the activated transmission number or the combination of transmission numbers configured for at least one PUCCH resource set or at least one PUCCH format is used for PUCCH joint repeated transmission of the plurality of PUCCH target resources to the plurality of TRPs of the base station.

[0204] Furthermore, in another possible implementation of this application, among the candidate set of transmission counts, the transmission count corresponding to the activation of the PUCCH resource is the first transmission count, wherein the transmission count of the activation of the PUCCH resource on each beam is determined according to the first transmission count in a preset manner.

[0205] Furthermore, in yet another possible implementation of this application, the aforementioned activated transmission count or combination of transmission counts includes a plurality of second transmission counts, each second transmission count indicating the number of transmissions at a transmission time corresponding to a PUCCH resource.
