Description

Information transmission method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information transmission method and apparatus.

Background

Currently, in a multi-point-to-TRP (multi-TRP) scenario, at least one base station transmits different Downlink Control Information (DCI) to the same terminal, and after the terminal receives the DCI, the terminal needs to determine at least one Transmission indication information (TCI) and further transmits a corresponding uplink channel to the at least one base station according to the at least one TCI.

In the related art, for example, when a terminal receives DCI 0 \ u 0 sent by one base station to indicate a Physical Uplink Shared Channel (PUSCH) sent by the terminal to one of the base stations, two TCIs may be determined through high-layer signaling, so that the middle terminal cannot determine which TCI of the two TCIs sends the Uplink Channel to the base station, which results in a communication failure between the terminal and the base station. For example, when receiving DCI sent by two base stations, a terminal instructs the terminal to send a Physical Uplink Control Channel (PUCCH) to the two base stations, and sends Uplink channels to the two base stations according to a default TCI, which causes the terminal to send the Uplink channels to the same base station, and if link conditions of the base station and the terminal are poor, transmission failure may be caused, and a gain for joint transmission of two TRPs may not be obtained.

Detailed Description

To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1 is a schematic view of an application scenario of the information transmission method provided in the present application. As shown in fig. 1, a multiple Transmission and Reception Point (multiple-TRP) communication scenario includes: a first base station 101, a second base station 102 and a terminal 103.

Wherein, a terminal 103 (e.g. a mobile phone) may interact with a first base station 101 and a second base station 102 respectively through a wireless network, and the first base station 101 may interact with the second base station 102 through the wireless network. Alternatively, the wireless network may be a 2G network, a 3G network, a 4G network, a 5G network, or the like.

Specifically, the first base station 101 and/or the second base station 102 may transmit DCI to the terminal 103, where the DCI is used to instruct the terminal 103 to transmit an uplink channel to the base station.

For example, when the first base station 101 and the second base station 102 interact with each other, any one of the first base station 101 and the second base station 102 sends DCI (the DCI includes control information sent by the first base station 101 and the second base station 102, respectively) to the terminal 103.

For example, the first base station 101 and the second base station 102 do not cross each other in time, the first base station 101 sends DCI (the DCI includes control information issued by the first base station 101) to the terminal 103, and the second base station 102 sends DCI (the DCI includes control information issued by the second base station 102) to the terminal 103.

It should be noted that fig. 1 exemplarily shows 2 base stations, and the specific number of the base stations is not particularly limited in the embodiment of the present application.

In practical applications, when any one of the first base station 101 and the second base station 102 transmits DCI to the terminal 103, the terminal 103 may determine a TCI according to the first higher layer configuration information received in advance, and transmit an uplink channel to the base station transmitting DCI according to the TCI. When the first base station 101 and the second base station 102 respectively send DCI to the terminal 103, the terminal 103 may determine two TCIs according to the second high-layer configuration information received in advance, send an uplink channel to the first base station 101 according to one of the TCIs, and send the uplink channel to the second base station 102 according to the other TCI. Therefore, the problem that the terminal cannot determine to send the uplink channel to the base station according to one of the two TCIs or cannot determine to send the uplink channel to the base station according to the TCI in the prior art is solved, and the communication reliability is improved.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a first flowchart illustrating an information transmission method provided in the present application. As shown in fig. 2, the information transmission method shown in this embodiment includes:

s201: the first base station sends high-level configuration information to the terminal.

Optionally, the higher layer configuration information sent to the terminal may also be any other base station in the multi-TRP communication scenario, for example, the second base station shown in fig. 1.

Alternatively, the higher layer configuration information may be first higher layer configuration information, or second higher layer configuration information.

The first higher layer configuration information includes: at least one Dedicated PUCCH identification (Dedicated PUCCH ID), wherein each Dedicated PUCCH identification corresponds to a TCI (Transmission configuration indication) of the PUCCH resource, and the TCI comprises the TCI identification.

The second higher layer configuration information includes: the method comprises the steps of identifying at least two different control resource set pools (Coreset Poolindex), at least one control resource set identification (Coreset ID) corresponding to each control resource set pool identification, and TCI of a control resource set where each control resource set identification is located, wherein the TCI comprises a TCI identification.

Further, after the first base station transmits the higher layer configuration information to the terminal, the terminal receives the higher layer configuration information.

S202: the first base station sends first downlink control information DCI to the terminal, and the first DCI is used for indicating the terminal to send an uplink channel.

Alternatively, the first DCI may be any one of DCI 0 \ u 0, DCI 1 \ u 1, DCI 1 \ u 2, and the like.

Optionally, the uplink channel may be a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH).

For example, when the first DCI is DCI 0 \ u 0, the uplink channel is PUSCH.

For example, when the first DCI is DCI 1 _u0, DCI 1 _u1, or DCI 1 _u2, the uplink channel is the PUCCH.

Further, after the first base station transmits the first DCI to the terminal, the terminal receives the first DCI.

S203: and the terminal determines first transmission indication information (TCI) of an uplink channel according to the high-level configuration information.

Specifically, when the uplink channel is the PUSCH, the first TCI is determined according to the first high-level configuration information, and when the uplink channel is the PUCCH, the first TCI is determined according to the second high-level configuration information.

It should be noted that, the specific method for determining the first TCI may refer to S303-S304 in fig. 3 and S405 in the embodiment of fig. 4. And will not be described in detail herein.

S204: and the first base station determines first transmission indication information (TCI) of an uplink channel according to the high-level configuration information.

Specifically, the process of the first base station performing S204 is the same as the process of the terminal performing S203, and the process of the first base station performing S204 is not described herein again.

It should be noted that the execution sequence of S201 to S204 may be adjusted. For example, the execution sequence of S201 to S204 may be: s201, S202, S204 and S203. For example, the execution sequence of S201 to S204 may also be: s204, S201, S202 and S203.

S205: and the terminal sends an uplink channel to the first base station according to the first TCI.

S206: the first base station receives an uplink channel from the terminal according to the first TCI.

The information transmission method provided by the embodiment comprises the following steps: the first base station sends high-level configuration information to the terminal; a first base station sends first Downlink Control Information (DCI) to a terminal, wherein the first DCI is used for indicating the terminal to send an uplink channel; the terminal determines first transmission indication information (TCI) of an uplink channel according to the high-level configuration information, and the first base station determines the first transmission indication information (TCI) of the uplink channel according to the high-level configuration information; the terminal sends an uplink channel to the first base station according to the first TCI; the first base station receives an uplink channel from the terminal according to the first TCI. In the method provided in this embodiment, the first transmission indication information TCI of the uplink channel is determined according to the high-layer configuration information, and a first TCI may be determined, so that the terminal can send the uplink channel according to the first TCI.

Next, a first technical problem of the prior art will be described.

The technical problems existing in the prior art are as follows: in the multi-TRP communication scenario shown in fig. 1, a terminal repeatedly transmits respective corresponding PUCCHs to a first base station and a second base station, for example, the terminal repeatedly transmits PUCCH-1 to the first base station and the terminal repeatedly transmits PUCCH-2 to the second base station. In the process that the terminal repeatedly sends PUCCH-1 to the first base station and repeatedly sends PUCCH-2 to the second base station, the terminal receives first DCI 0_0 sent by the first base station, and the first DCI 0_0 is used for indicating the terminal to send PUSCH to the first base station. In the existing communication protocol, the TCI of the PUCCH resource corresponding to the lowest dedicated PUCCH identifier in the dedicated PUCCH resources is determined as the TCI of the PUSCH. Because there may be two TCIs corresponding to the PUCCH resource in the lowest dedicated PUCCH identifier, two TCIs of the PUSCH may be determined according to the existing communication protocol, so that the terminal cannot determine to transmit the PUSCH to the base station according to one of the two TCIs, thereby causing communication failure.

To solve the first technical problem, the present application provides an information transmission method for solving the first technical problem, and specifically, please refer to the embodiment in fig. 3.

Fig. 3 is a schematic flow chart of an information transmission method provided in the present application. As shown in fig. 3, the information transmission method provided in this embodiment includes:

s301: the first base station sends first high-layer configuration information to the terminal, wherein the first high-layer configuration information comprises at least one special PUCCH identifier and TCI of PUCCH resources corresponding to each special PUCCH identifier, and the TCI comprises the TCI identifier.

For example, the dedicated PUCCH identifier in the first higher layer configuration information and the TCI of the PUCCH resource corresponding to the dedicated PUCCH identifier have a correspondence relationship as shown in table 1 below.

TABLE 1

Dedicated PUCCH identification	Transmitting indication information
		2	TCI 3；TCI 2
3	TCI 4
		4	TCI 3；TCI 5
6	TCI 2
		7	TCI 1；TCI 4

In table 1, 2, 3, 4, 6, and 7 in the dedicated PUCCH identification column are all dedicated PUCCH identifications.

In table 1, the TCI 3, TCI 2, TCI4, TCI 5, and TCI 1 in the transmission indication information are all TCIs, where 1, 2, 3, 4, and 5 are TCI identifiers.

For example, the TCIs corresponding to the dedicated PUCCH identity 2 are TCI 3 and TCI 2.

For example, the TCI corresponding to the dedicated PUCCH identification 3 is TCI 4.

S302: the first base station sends first Downlink Control Information (DCI) to the terminal, wherein the first DCI is used for indicating the terminal to send a Physical Uplink Shared Channel (PUSCH).

S303: and the terminal determines an intermediate special PUCCH identifier according to the number of TCIs corresponding to the PUCCH resources by the special PUCCH identifier, and the number of TCIs corresponding to the PUCCH resources by the intermediate special PUCCH identifier is a first preset value.

Wherein each dedicated PUCCH identity corresponds to at least one TCI. The first preset value may be 1 or 2.

For example, in table 1, the number of TCIs corresponding to the dedicated PUCCH identifier 3 is 1 (i.e., TCI 4), and the number of TCIs corresponding to the dedicated PUCCH identifier 6 is 1 (i.e., TCI 2). Therefore, when the first preset value is 1, the middle dedicated PUCCH identifiers are 3 and 6, respectively.

For example, in table 1, the number of TCIs corresponding to the dedicated PUCCH identifier 2 is 2 (i.e., TCI 3 and TCI 2), the number of TCIs corresponding to the dedicated PUCCH identifier 4 is 2 (i.e., TCI 3 and TCI 5), and the number of TCIs corresponding to the dedicated PUCCH identifier 7 is 2 (i.e., TCI 1 and TCI 4). Therefore, when the first preset value is 2, the intermediate dedicated PUCCH identifiers are 2, 4, and 7, respectively.

S304: and the terminal determines the first TCI of the PUSCH according to the intermediate special PUCCH identifier.

In a possible embodiment, the first preset value is equal to 1; a target dedicated PUCCH identity may be determined among the intermediate dedicated PUCCH identities; and determining the TCI of the PUCCH resources corresponding to the target special PUCCH identification as a first TCI of an uplink channel (PUSCH), wherein the target special PUCCH identification is the minimum identification in the intermediate special PUCCH identifications.

For example, in table 1, when the first preset value is equal to 1, the target dedicated PUCCH identifier determined in the intermediate dedicated PUCCH identifiers is 3, and the TCI corresponding to the target dedicated PUCCH identifier 3 is TCI4, so that the TCI4 is determined as the first TCI.

In another possible embodiment, the first preset value is equal to 1; a target TCI may be determined in the TCI of the PUCCH resource corresponding to the intermediate dedicated PUCCH identity; determining a target TCI as a first TCI of an uplink channel (PUSCH); wherein, the TCI identifier of the target TCI is the minimum identifier or the maximum identifier in the TCI identifiers of the PUCCH resources corresponding to the intermediate dedicated PUCCH identifier.

For example, in table 1, when the first preset value is equal to 1, the TCI corresponding to the intermediate dedicated PUCCH identifier 3 is TCI4, and the TCI corresponding to the intermediate dedicated PUCCH identifier 6 is TCI 2. When the TCI identifier of the target TCI is the minimum identifier in the TCI identifiers of the PUCCH resources corresponding to the intermediate dedicated PUCCH identifier, determining the TCI 2 as the target TCI; and when the TCI identifier of the target TCI is the maximum identifier in the TCI identifiers of the PUCCH resources corresponding to the intermediate dedicated PUCCH identifier, determining the TCI4 as the target TCI.

In another possible embodiment, the first preset value is equal to 2; a target dedicated PUCCH identity may be determined among the intermediate dedicated PUCCH identities; determining a target TCI according to the target special PUCCH identifier; determining a target TCI as a first TCI of an uplink channel (PUSCH); and the target special PUCCH identification is the minimum identification in the middle special PUCCH identifications.

For example, in table 1, when the first preset value is equal to 2, the intermediate dedicated PUCCH identities are 2, 4, and 7, respectively. The target dedicated PUCCH identification determined in the intermediate dedicated PUCCH identification is 2.

Optionally, the target TCI may be determined according to the position of the TCI of the PUCCH resource corresponding to the target dedicated PUCCH identifier; and the target TCI is a TCI corresponding to a first position or a TCI corresponding to a second position in the positions of the TCI corresponding to the PUCCH resources.

It should be noted that the position of the TCI is the position of the TCI in the preset arrangement order.

For example, in table 1, the preset ordering of TCIs corresponding to the target dedicated PUCCH identifier 2 is TCI 3 and TCI 2. The first position is the position of a first TCI in the preset arrangement sequence, and the second position is the position of a second TCI in the preset arrangement sequence.

For example, when the target TCI is the TCI corresponding to the first location, the target TCI is TCI 3; when the target TCI is the TCI corresponding to the second position, the target TCI is TCI 2.

Optionally, the target TCI may be determined according to the TCI identifier of the PUCCH resource corresponding to the target dedicated PUCCH identifier; the TCI identifier of the target TCI is the minimum identifier or the maximum identifier in the TCI identifiers of the PUCCH resources corresponding to the target special PUCCH identifier.

For example, in table 1, when the target dedicated PUCCH identifier is 2, the corresponding TCIs are TCI 3 and TCI 2, respectively, and therefore when the TCI identifier of the target TCI is the minimum identifier in the TCI identifiers of the PUCCH resources corresponding to the target dedicated PUCCH identifier, the target TCI is TCI 2; and when the TCI identifier of the target TCI is the maximum identifier in the TCI identifiers of the PUCCH resources corresponding to the target special PUCCH identifier, the target TCI is TCI 3.

In another possible embodiment, the target TCI may also be determined according to the TCI identifier of the PUCCH resource corresponding to each dedicated PUCCH identifier; determining a target TCI as a first TCI of an uplink channel; the TCI identifier of the target TCI is the minimum identifier or the maximum identifier in the TCI identifiers of the PUCCH resources corresponding to the special PUCCH identifier.

For example, when the TCI identifier of the target TCI is the minimum identifier in the TCI identifiers of the PUCCH resources corresponding to the dedicated PUCCH identifier, the target TCI is TCI 1; and when the TCI identifier of the target TCI is the maximum identifier in the TCI identifiers of the PUCCH resources corresponding to the special PUCCH identifier, the target TCI is TCI 5.

S305: and the first base station determines an intermediate special PUCCH identifier according to the number of TCIs of the PUCCH resources corresponding to the special PUCCH identifier, and the number of TCIs of the PUCCH resources corresponding to the intermediate special PUCCH identifier is a first preset value.

Specifically, the process of the first base station performing S304 is the same as the process of the terminal performing S303, and the process of the first base station performing S305 is not described herein again.

S306: and the first base station determines a first TCI of the PUSCH according to the intermediate dedicated PUCCH identification.

Specifically, the process of the first base station performing S306 is the same as the process of the terminal performing S304, and the process of the first base station performing S306 is not described herein again.

It should be noted that the execution sequence of S303-S304 and the execution sequence of S305-S306 may be adjusted, that is, S303-S304 may be executed after S305-S306 are executed.

S307: and the terminal sends the PUSCH to the first base station according to the first TCI.

S308: the first base station receives a PUSCH from the terminal according to the first TCI.

The information transmission method provided by the embodiment comprises the following steps: a first base station sends first high-level configuration information to a terminal, wherein the first high-level configuration information comprises at least one special PUCCH identifier, TCI of PUCCH resources corresponding to each special PUCCH identifier, and the TCI comprises TCI identifiers; the terminal receives first Downlink Control Information (DCI) from a first base station, wherein the first DCI is used for indicating the terminal to send a Physical Uplink Shared Channel (PUSCH) to one of the base stations; the terminal determines an intermediate special PUCCH identifier according to the number of TCIs of PUCCH resources corresponding to each special PUCCH identifier, wherein the number of TCIs of PUCCH resources corresponding to the intermediate special PUCCH identifier is a first preset value; the terminal determines a first TCI of the PUSCH according to the intermediate special PUCCH identifier; the first base station determines an intermediate special PUCCH identifier according to the number of TCIs of the PUCCH resources corresponding to the special PUCCH identifier, wherein the number of TCIs of the PUCCH resources corresponding to the intermediate special PUCCH identifier is a first preset value; the first base station determines a first TCI of the PUSCH according to the intermediate special PUCCH identifier; the terminal sends PUSCH to the first base station according to the first TCI; the first base station receives a PUSCH from the terminal according to the first TCI. In the method, the terminal can determine the only first TCI of the PUSCH according to the intermediate special PUCCH identification, and normal communication between the terminal and the first base station is guaranteed. The problem that the terminal cannot determine whether to send the PUSCH to the base station according to one of the two TCIs in the technology, so that communication failure is caused is solved.

Next, a second technical problem of the prior art will be described.

The technical problems existing in the prior art are as follows: in the multi-TRP communication scenario shown in fig. 1, a first base station and a second base station each transmit DCI to a terminal, and the DCI is used to instruct the terminal to transmit a PUCCH to the first base station. For example, a first base station transmits a first DCI (e.g., DCI 1 \ u 0) to a terminal, and a second base station transmits a second DCI (e.g., DCI 1 \ u 0) to the terminal. In practical applications, after receiving the first DCI, the terminal needs to transmit a PUCCH (e.g., PUCCH-1) to the first base station according to one TCI, and after receiving the second DCI, the terminal needs to transmit a PUCCH (e.g., PUCCH-2) to the second base station according to another TCI. However, according to the existing communication protocol, two PUCCHs sent by the terminal do not have a TCI corresponding to each other, and at this time, the two PUCCHs are sent by adopting the default TCI, so that the PUCCHs sent by the terminal are oriented to the same base station, and if the link condition between the base station and the terminal is poor, transmission failure is caused, and the gain of joint transmission of two TRPs cannot be obtained.

In view of the second technical problem, the present application provides an information transmission method for solving the second technical problem, and specifically, please refer to the embodiment in fig. 4.

Fig. 4 is a third schematic flowchart of the information transmission method provided in the present application. As shown in fig. 4, the information transmission method provided in this embodiment includes:

s401: the first base station sends second high-level configuration information to the terminal, wherein the second high-level configuration information comprises at least two different control resource set pool identifications, at least one control resource set identification corresponding to each control resource set pool identification and TCI of a control resource set where each control resource set identification is located, and the at least two different control resource set pool identifications comprise a first control resource set pool identification and a second control resource set pool identification.

Optionally, the second base station may also send the second higher layer configuration information to the terminal.

For example, at least two different control resource set pool identifiers in the second high-level configuration information, at least one control resource set identifier corresponding to each control resource set pool identifier, and the TCI of the control resource set in which each control resource set identifier is located have the corresponding relationship shown in table 2 below.

TABLE 2

Controlling resource set identification	Control resource pool identification	Transmitting indication information
			0	1	TCI 3
1	0	TCI 2
			2	1	TCI 4
3	0	TCI 8

In table 2, the first control resource pool identifier is 0, and the second control resource pool identifier is 1. In practical application, the position of the control resource pool identifier which is not configured is set to 0.

For example, at least two different control resource set pool identifiers in the second high-level configuration information, at least one control resource set identifier corresponding to each control resource set pool identifier, and the TCI of the control resource set in which each control resource set identifier is located have the corresponding relationship as shown in table 3 below.

TABLE 3

Controlling resource set identification	Control resource pool identification	Transmitting indication information
			0	1	TCI 3
1	1	TCI 2
			2	1	TCI 4
3	0	TCI 8

S402: the first base station sends second high-level configuration information to the second base station.

S403: the first base station sends first Downlink Control Information (DCI) to the terminal, and the first DCI is used for indicating the terminal to send a first Physical Uplink Control Channel (PUCCH) to one of the base stations.

Alternatively, the first DCI may be DCI 1 \ u 0, DCI 1 \ u 1, DCI 1 \ u 2, or the like.

S404: and the second base station transmits second DCI to the terminal, wherein the second DCI is used for indicating the terminal to transmit a second PUCCH.

Alternatively, the second DCI may be DCI 1_0, DCI 1_1, DCI 1_2, or the like.

Alternatively, the execution order of S403 and S404 may be changed. For example, the execution order may be: s404 and S403.

S405: and the terminal determines the first TCI of the first PUCCH in the second high-level configuration information according to the first control resource pool identifier.

For example, in table 2, at least one control resource set identifier corresponding to the first control resource set pool identifier 0 is 1 and 3, respectively. When the current first target control resource set identifier is the smallest identifier in the control resource set pool identifier corresponding to the at least one control resource set identifier, the first target control resource set identifier is 1, and thus, the TCI (i.e., TCI 2) of the control resource set where the first target control resource set identifier is located is determined as the first TCI of the first PUCCH. When the current first target control resource set identifier is the largest identifier in the at least one control resource set identifier corresponding to the first control resource set pool identifier, the first target control resource set identifier is 3, and thus, the TCI (i.e., TCI 8) of the control resource set where the first target control resource set identifier is located is determined to be the first TCI of the first PUCCH.

For example, in table 3, the first control resource set pool identifier 0 corresponds to only one control resource set identifier 3, so that the control resource set identifier 3 is determined as the first target control resource set identifier, and the TCI (i.e., TCI 8) of the control resource set where the first target control resource set identifier is located is determined as the first TCI of the first PUCCH.

S406: and the terminal determines a second TCI of a second PUCCH in second high-level configuration information according to the second control resource pool identifier.

In a possible implementation manner, a second target control resource set identifier may be determined in the second high-level configuration information according to the second control resource set pool identifier, where the second target control resource set identifier is a minimum identifier or a maximum identifier in at least one control resource set identifier corresponding to the second control resource set pool identifier; and determining the TCI of the control resource set in which the second target control resource set identification is positioned as the second TCI of the second PUCCH.

For example, in table 2, at least one control resource set identifier corresponding to the second control resource set pool identifier 1 is 0 and 2, respectively. When the current second target control resource set identifier is the minimum identifier in the at least one control resource set identifier corresponding to the second control resource set pool identifier, the second target control resource set identifier is 0, and thus, the TCI (i.e., TCI 3) of the control resource set where the second target control resource set identifier is located is determined as the second TCI of the second PUCCH. When the current second target control resource set identifier is the largest identifier in the at least one control resource set identifier corresponding to the second control resource set pool identifier, the second target control resource set identifier is 2, and thus, the TCI (i.e., TCI 4) of the control resource set in which the second target control resource set identifier is located is determined as the second TCI of the second PUCCH.

For example, in table 3, at least one control resource set identifier corresponding to the second control resource set pool identifier 1 is 0, 1, and 2, and when the current second target control resource set identifier is the minimum identifier in the at least one control resource set identifier corresponding to the second control resource set pool identifier, the second target control resource set identifier is 0, so that the TCI (i.e., TCI 3) of the control resource set where the second target control resource set identifier is located is determined as the second TCI of the second PUCCH. When the current second target control resource set identifier is the largest identifier in the at least one control resource set identifier corresponding to the second control resource set pool identifier, the second target control resource set identifier is 2, and thus, the TCI (i.e., TCI 4) of the control resource set in which the second target control resource set identifier is located is determined as the second TCI of the second PUCCH.

Alternatively, the execution sequence of S405 and S406 may be changed, or the execution methods in S405 and S406 may be executed simultaneously.

S407: and the first base station determines the first TCI of the first PUCCH in the second high-level configuration information according to the first control resource pool identification.

It should be noted that the process of the first base station performing S407 is the same as the process of the terminal performing S405, and the process of performing S407 is not described herein again.

S408: and the second base station determines a second TCI of a second PUCCH in the second high-level configuration information according to the second control resource pool identifier.

S411: and the terminal sends a second PUCCH to the second base station according to the second TCI.

S412: and the second base station receives a second PUCCH from the terminal according to the second TCI.

It should be noted that the execution sequence of S405-S412 may be performed in other execution sequences besides the execution sequence shown in fig. 4.
