Description

Indication method and device for determining PUCCH repeated transmission times

Technical Field

The present application relates to communications technologies, and in particular, to an indication method and an indication device for determining PUCCH retransmission times.

Background

In the current 5th generation New air interface (5G) mobile communication system, in the process of researching the coverage enhancement of the Physical Uplink Control Channel (PUCCH) of the 5G New air interface (New Radio, NR), a scheme for dynamically indicating the number of times of retransmission (retransmission number) of the PUCCH is proposed. Specifically, the dynamic indication of the repetition number of the PUCCH includes an implicit indication mode and an explicit indication mode. In the two schemes, after configuring the repetition number, the base station needs to transmit and receive the PUCCH according to the configured repetition number.

In the explicit indication method, the number of repeated transmissions of the PUCCH is configured independently. For example, when a PUCCH Resource Indication (PRI) field of 3bits and a PUCCH repetition number Indication field of 2bits are used, the base station may indicate a case of repeated transmission of 32 different PUCCH resources (that is, a combination including 8 PUCCH resources and 4 repeated transmission times).

In the implicit indication mode, since the same indication information carries more functions, the indication flexibility of the PUCCH resource is reduced when the repetition is turned on.

For example, when the PRI field needs to indicate the PUCCH resource and the number of retransmission times at the same time, if the base station configures 4 different numbers of retransmission times for the same PUCCH resource, the base station may indicate the case of retransmission of 8 different PUCCH resources (i.e., including a combination of 2 PUCCH resources and 4 numbers of retransmission times) by using a PUCCH resource of 3 bits. In this case, when the channel condition is good and the PUCCH does not need to be repeatedly transmitted, the terminal can select only one of two different PUCCH resources.

In summary, if the base station indicates that the terminal dynamically determines the number of times of PUCCH retransmission in an implicit manner, the flexibility of the base station indicating the PUCCH resource is severely limited.

Detailed Description

In order to make the technical solutions disclosed in the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the accompanying drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

In the current 5G mobile communication system, in the process of researching the PUCCH coverage enhancement of the 5G new air interface, after configuring the repetition number, the base station needs to transmit and receive the PUCCH according to the configured repetition number. Specifically, the dynamic indication of the repetition number of the PUCCH includes implicit and explicit indication modes.

In the explicit indication mode, both PUCCH resource selection and the number of repeated transmissions are configured independently. For example, when a PUCCH resource indication field of 3bits and a PUCCH repetition indication field of 2bits are used, the base station may indicate a case of 32 different PUCCH retransmission (i.e., a combination including 8 PUCCH resources and 4 retransmission times).

In the implicit indication mode, since the same indication information carries more functions, the indication flexibility is decreased in the case of starting repetition. For example, when the PRI field needs to indicate the PUCCH resource and the number of retransmission times at the same time, if the base station configures 4 different numbers of retransmission times for the same PUCCH resource, the base station may indicate the case of retransmission of 8 different PUCCH resources (i.e., including a combination of 2 PUCCH resources and 4 numbers of retransmission times) by using a PUCCH resource of 3 bits. In this case, when the channel condition is good and the PUCCH does not need to be repeatedly transmitted, the terminal can select only one of two different PUCCH resources, and thus, the flexibility of resource indication is severely limited.

For example, when the number of PUCCH retransmission times is dynamically indicated by an implicit indication manner, the higher layer signaling additionally configures a field for each PUCCH resource to indicate the number of dynamic retransmission times corresponding to the current PUCCH resource. Then, the number of repeated transmissions of the PUCCH is implicitly indicated by reusing an existing bit field in Downlink Control Information (DCI). For example, the transmission resource of the PUCCH and the corresponding number of repeated transmissions are simultaneously indicated using the PRI field. When the PRI domain is adopted, the terminal determines a PUCCH resource set (one resource set may include multiple PUCCH resources) according to the number of bits of the UCI to be transmitted, and then determines a specific PUCCH resource from the resource set through the PRI in the signaling. And meanwhile, determining the repeated transmission times of the PUCCH according to the PRI.

When the number of times of repeated transmission of the PUCCH is dynamically indicated by adopting an implicit indication mode of reusing the DCI domain, the configuration needs to be carried out through RRC parameters. After the configuration is completed, the base station and the terminal side need to transmit and receive the PUCCH according to the currently configured repeated transmission times. Since the same indication information carries more functions, the indication flexibility of the PUCCH resource is limited. When the channel condition is good and the number of times of PUCCH retransmission does not need to be dynamically indicated, or only a small number of times of PUCCH retransmission is needed, the number of available PUCCH resources is small, which results in severely limited flexibility of resource indication. Taking a 3-bit PRI field as an example, table 1 shows flexibility of PUCCH resource selection when the PRI field needs to indicate PUCCH retransmission times and does not indicate PUCCH retransmission times. When the PRI field is used to additionally indicate the number of PUCCH repetition transmissions, the number of selectable PUCCH resources is significantly reduced.

Table 1: PRI indicates flexibility contrast

Preferred embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.

In the embodiment of the present disclosure, the implementation of determining the number of times of PUCCH retransmission is mainly divided into a terminal side and a base station side, which are described below.

A terminal side: after receiving target information sent by a base station, determining the number of times of PUCCH repeated transmission in a dynamic mode or a semi-static mode, wherein the basis of the terminal for determining the number of times of PUCCH repeated transmission is the target information, and the target information specifically comprises first target information or second target information sent by the base station.

A base station side: and generating target information, specifically including the first target information or the second target information, so as to instruct the terminal to adopt a dynamic mode or a semi-static mode and determine the repeated transmission times of the PUCCH.

The following description is made first for the case where the terminal side determines the number of PUCCH retransmission times. Referring to fig. 1, in the embodiment of the present disclosure, a specific process for determining the number of times of PUCCH retransmission is as follows:

step 101: the terminal receives target information sent by the base station, wherein the target information comprises first target information or second target information.

In the embodiment of the present application, in order to enable the terminal to adopt a dynamic mode or a semi-static mode through an optional mode, and determine the number of times of PUCCH retransmission, the base station may configure a plurality of types of configuration information in a semi-static manner in advance through a high-level signaling and issue the configuration information to the terminal. It should be emphasized that the following configuration information is a plurality of parameters that can be selected in parallel, and the terminal can determine the number of PUCCH retransmission times by selecting one of them (for example, BWP configuration information) in implementation.

Specifically, the first target information includes any one of: search Space (SS) configuration information, COntrol REsource SET (CORESET) configuration information, or BandWidth Part (BWP) configuration information, or PDCCH candidate (PDCCH candidate) or detection timing (MO) grouping information. The target information is high-level signaling semi-static configuration.

Correspondingly, in order to enable the terminal to distinguish a dynamic mode or a semi-static mode through an optional mode and determine the number of times of repeated transmission of the PUCCH, the base station also sends various dynamic indications to the terminal in the communication process. Specifically, the second target information includes any one of: media Access Control (MAC) Control Element (CE) or Control information carried in DCI. In implementation, the terminal may determine the number of repeated PUCCH transmissions by simply selecting one of the two (e.g., control information carried in DCI).

Step 102: and the terminal determines the repeated transmission times of the PUCCH by adopting a dynamic mode or a semi-static mode based on the target information.

First, it should be noted that, if the terminal determines the number of PUCCH retransmission times in a semi-static manner based on the target information, the number of retransmission times is at least one. That is, the case where the terminal determines the number of times of retransmission of the PUCCH in the semi-static manner includes at least a case where the number of times of retransmission is one, that is, a case where retransmission is not performed.

In the implementation process, step 102 specifically includes the terminal determining the number of times of PUCCH retransmission in a dynamic manner or a semi-static manner based on the first target information; or the terminal determines the number of times of PUCCH repeated transmission by adopting a dynamic mode or a semi-static mode based on the second target information.

The first target information is any one of Search Space configuration information, core configuration information, BWP configuration information, PDCCH candidate packet information, and PDCCH MO packet information. The following is to describe in detail the determination of the number of times of PUCCH retransmission by selecting one of the information by the terminal in each case, and specifically includes:

in the first case: and if the target information is the Search Space configuration information in the first target information, the terminal determines the repeated transmission times of the PUCCH by adopting a dynamic mode or a semi-static mode based on the target information. The following detailed description is divided into two ways, which specifically include:

referring to fig. 2, the first method:

step 11: the terminal acquires the state information of PUCCH repetition enabling in the Search Space configuration information.

The base station configures the state information of the PUCCH repetition associating in advance in the Search Space configuration information, and configures an indication action for each type of state information. Therefore, in the implementation process, the terminal needs to first acquire the state information of the PUCCH repetition enabling in the Search Space configuration information corresponding to the received DCI.

Step 12: and if the state information is in an enabling state, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode.

Based on the pre-configuration of the base station, when the terminal determines that the received status information is in an enabled status (for example, when the enabled status is enabled), the terminal correspondingly determines the number of PUCCH retransmission times in a dynamic manner, for example, the number of PUCCH retransmission times may be determined in a manner indicated in the third column or the fourth column of table 1.

Step 13: and if the state information is in a non-enabled state, the terminal determines the repeated transmission times of the PUCCH in a semi-static mode.

Likewise, when the terminal determines that the received status information is in a non-enabled status (for example, when the enabled status is disabled) based on the configuration of the base station in advance, in this case, the terminal parses the information field in the DCI according to the definition in the existing Rel-15/16, that is, correspondingly determines the number of PUCCH retransmission times in a semi-static manner, for example, the number of PUCCH retransmission times may be determined in the manner indicated by the second column in table 1.

In addition, the first mode also includes the following cases: if the terminal does not acquire the state information of the PUCCH repetition enable in the Search Space configuration information, the terminal determines the number of times of PUCCH repeated transmission by adopting a semi-static mode because the base station does not configure the state information of the PUCCH repetition enable in the Search Space configuration information.

Referring to fig. 3, the second method:

step 11': the terminal receives the first configuration information, acquires a Search Space ID according to the Search Space configuration information, and determines a first association relation between the Search Space ID and the first configuration information, wherein the first configuration information at least comprises a Search Space ID set configured in PUCCH resources, and the Search Space ID set represents that the terminal is allowed to determine the number of times of PUCCH repeated transmission in a dynamic mode.

Because the base station generates the first configuration information in advance based on the Search Space ID set, and configures the indication action for the first configuration information correspondingly, so as to indicate the terminal to determine the number of times of PUCCH retransmission in a dynamic manner.

Therefore, in the implementation process, the terminal needs to first acquire the Search Space ID in the Search Space configuration information, and accordingly, the first configuration information representation acquired by the terminal determines the number of times of PUCCH retransmission in a dynamic manner.

In order to further judge a mode of determining the number of repeated transmissions corresponding to the associated Search Space ID additionally configured for the PUCCH resource indicated by the PRI field in the DCI, the terminal acquires a first association relationship between the Search Space ID and the first configuration information.

Step 12': and if the first association relationship represents that the first configuration information comprises the Search Space ID, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode.

In the implementation process, if the first configuration information includes the Search Space ID in the Search Space configuration information acquired by the terminal in advance, that is, the first association representation first configuration information includes the Search Space ID, the terminal determines the number of times of PUCCH retransmission in a dynamic manner.

Step 13': and if the first association relationship represents that the first configuration information does not include the Search Space ID, the terminal determines the repeated transmission times of the PUCCH in a semi-static mode.

In the implementation process, if the first configuration information does not include the Search Space ID in the Search Space configuration information acquired by the terminal in advance, that is, the first association relationship represents that the first configuration information does not include the Search Space ID, the terminal determines the number of times of PUCCH retransmission in a semi-static manner.

In addition, the second mode also includes the following cases: if the terminal does not receive the first configuration information, which is caused by the base station not configuring the first configuration information, the terminal determines the number of times of PUCCH retransmission in a semi-static manner.

In the second case: and if the target information is the CORESET configuration information in the first target information, the terminal determines the repeated transmission times of the PUCCH by adopting a dynamic mode or a semi-static mode based on the target information. The following detailed description is divided into two ways, which specifically include:

referring to fig. 4, the method (one):

step 21: the terminal acquires the state information of PUCCH repetition enabling in CORESET configuration information.

The base station configures the state information of the PUCCH repetition enabling in the CORESET configuration information in advance, and configures indication actions for each type of state information correspondingly. Therefore, in the implementation process, the terminal needs to first acquire the state information of the PUCCH repetition enabling in the CORESET configuration information corresponding to the received DCI.

Step 22: and if the state information is in an enabling state, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode.

Step 23: and if the state information is in a non-enabled state, the terminal determines the repeated transmission times of the PUCCH in a semi-static mode.

Similarly, when the terminal determines that the received status information is in a non-enabled status (for example, when the enabled status is disabled) based on the configuration of the base station in advance, in this case, the terminal parses the information field in the DCI according to the definition in the existing Rel-15/16, that is, correspondingly determines the number of PUCCH retransmission times in a semi-static manner, for example, the number of PUCCH retransmission times may be determined in the manner indicated in the second column of table 1.

The method (a) further includes the following cases: if the terminal does not acquire the state information of the PUCCH repetition attempt in the CORESET configuration information, which is caused by the fact that the base station does not configure the state information of the PUCCH repetition attempt in the CORESET configuration information, the terminal determines the number of times of PUCCH repeated transmission by adopting a semi-static mode.

Referring to fig. 5, the method (ii):

step 21': and the terminal receives the second configuration information, acquires a CORESET ID according to the CORESET configuration information, and determines a second association relationship between the CORESET ID and the second configuration information, wherein the second configuration information at least comprises a CORESET ID set configured in PUCCH resources, and the CORESET ID set representation allows the terminal to determine the PUCCH repeated transmission times in a dynamic mode.

The base station generates second configuration information in advance based on the CORESET ID set, and correspondingly configures an indication action for the second configuration information so as to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode.

Therefore, in the implementation process, the terminal needs to first acquire the CORESET ID in the CORESET configuration information where the DCI is transmitted, and correspondingly, the second configuration information representation acquired by the terminal determines the PUCCH repetition transmission times in a dynamic manner.

In order to further judge the mode of determining the number of repeated transmissions corresponding to the CORESET ID associated with the PUCCH resource extra configuration indicated by the PRI field in the DCI, the terminal acquires a second association relationship between the CORESET ID and the first configuration information.

Step 22': and if the second association relationship represents that the second configuration information comprises the CORESET ID, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode.

In the implementation process, if the second configuration information includes a CORESET ID in the CORESET configuration information acquired by the terminal in advance, that is, the second association representation includes the CORESET ID in the second configuration information, the terminal determines the number of times of PUCCH retransmission in a dynamic manner.

Step 23': and if the second association relationship represents that the second configuration information does not comprise the CORESET ID, the terminal determines the repeated transmission times of the PUCCH in a semi-static mode.

In the implementation process, if the second configuration information does not include the CORESET ID in the CORESET configuration information acquired by the terminal in advance, that is, the first association relationship represents that the second configuration information does not include the CORESET ID, the terminal determines the number of times of PUCCH repeat transmission in a semi-static manner.

The method (a) further includes the following cases: and if the terminal does not receive the second configuration information, which is caused by the fact that the base station does not configure the second configuration information, the terminal determines the repeated transmission times of the PUCCH in a semi-static mode.

In the third case: and if the target information is the BWP configuration information in the first target information, the terminal determines the number of times of PUCCH repeated transmission by adopting a dynamic mode or a semi-static mode based on the target information. The following detailed description, referring to fig. 6, specifically includes:

step 31: the terminal acquires third configuration information according to the BWP configuration information, where the third configuration information is state information of a PUCCH repetition sounding in a BWP where a PUCCH channel is located, or state information of a PUCCH repetition sounding in the BWP corresponding to DCI.

Because the base station configures the state information of PUCCH repetition activation in advance in the BWP where the PUCCH channel is located, and correspondingly configures indication actions for each state information; or, the base station configures state information of PUCCH repetition enabling in the BWP corresponding to the DCI in advance, and configures an indication action for each type of state information. Therefore, in the implementation process, the terminal needs to first acquire the third configuration information, that is, the state information of the PUCCH repetition sounding in the BWP where the PUCCH channel is located, or the state information of the PUCCH repetition sounding in the BWP corresponding to the DCI.

Step 32: and if the state information is in an enabling state, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode.

Step 33: and if the state information is in a non-enabled state, the terminal determines the repeated transmission times of the PUCCH in a semi-static mode.

The method (a) further includes the following cases: if the terminal does not successfully acquire the third configuration information, which is caused by that the base station does not configure the state information of the PUCCH repetition sounding in the BWP where the PUCCH channel is located and the state information of the PUCCH repetition sounding in the BWP corresponding to the DCI, the terminal determines the number of PUCCH retransmission times in a semi-static manner.

In a fourth case: if the target information is the packet information of the PDCCH candidate or the PDCCH MO in the first target information, the terminal determines the number of times of PUCCH retransmission by using a dynamic method or a semi-static method based on the target information. The following detailed description, referring to fig. 7, specifically includes:

step 41: the terminal acquires the location information of the PDCCH candidate or PDCCH MO.

In the implementation, in order to match to which packet the PDCCH candidate group corresponding to the received DCI belongs, the terminal first acquires the location information of the PDCCH candidate or PDCCH MO from its own attribute, and the location information is usually represented in the form of an index.

Step 42: and the terminal acquires a first target packet and a second target packet according to the packet information, wherein the first target packet and the second target packet both comprise position packet information of PDCCH candidate or position packet information of PDCCH MO.

Since the base station configures the first target packet and the second target packet in advance based on the position packet information, and configures the indication action for each target packet correspondingly. Therefore, in the implementation process, the terminal needs to first obtain the first target packet and the second target packet according to the packet information.

The first target packet and the second target packet each include PDCCH candidate location packet information or PDCCH MO location packet information, that is, PDCCH candidate location packet information or PDCCH MO location packet information for dividing the first target packet and the second target packet.

In the implementation process, how to determine the number of times of PUCCH retransmission by using the PDCCH candidate group corresponding to DCI received by the terminal needs to match the location information with the first target packet or the second target packet one by one.

Step 43: and if the position information is matched with the first target group, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode, wherein the first target group is preset and indicates the terminal to determine a PDCCH candidate set or a PDCCH MO set of the repeated transmission times of the PUCCH in the dynamic mode.

Specifically, if the location information matches the first target packet, the terminal determines the number of times of PUCCH retransmission in a dynamic manner according to the preset of the base station regardless of whether the type of the first target packet is the PDCCH candidate set or the PDCCH MO set.

And step 44: and if the position information is matched with a second target group, the terminal determines the repeated transmission times of the PUCCH in a semi-static mode, wherein the second target group is preset and indicates the terminal to determine a PDCCH candidate set or a PDCCH MO set of the repeated transmission times of the PUCCH in the semi-static mode.

Specifically, if the location information is matched with the second target packet, the terminal determines the number of PUCCH retransmission times in a semi-static manner according to the preset of the base station regardless of whether the type of the second target packet is the PDCCH candidate set or the PDCCH MO set.

The method (a) further includes the following cases: and if the terminal does not receive the packet information, which is caused by the fact that the base station does not configure the packet information, the terminal determines the repeated transmission times of the PUCCH in a semi-static mode.

It should be added here that the packet information is acquired by any one of the following manners:

(1) And obtaining the configuration information of the Search Space. In this case, the terminal acquires the search space-related configuration information and determines a packet of PDCCH candidate or PDCCH MO according to packet information included in the related configuration information.

(2) And obtaining the PUCCH resource related configuration information indicated by the PRI domain in the DCI. In this case, the terminal identifies a PDCCH candidate or a PDCCH MO packet based on packet information included in PUCCH resource related configuration information indicated in the PRI field in the DCI.

(3) The acquisition is predefined according to the protocol. In this case, the terminal determines the packet of PDCCH candidate or PDCCH MO according to a packet mode predefined in the protocol.

It is considered that the indication in the second target information is any one of control information carried in the MAC CE or the DCI. The following is explained in detail in different cases, and specifically includes:

in the fifth case: and if the target information is the MAC CE in the second target information, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode based on the target information. The following detailed description, with reference to fig. 8, specifically includes:

step 51: and when the MAC CE takes effect, the terminal acquires the state information of the PUCCH repetition enabling carried in the MAC CE.

The base station configures the state information of the PUCCH repetition associating in advance in the MAC CE, and configures indication actions corresponding to each type of state information. Therefore, in the implementation process, the terminal needs to first acquire the state information of the PUCCH repetition enabling in the CORESET configuration information corresponding to the received DCI.

In this step, the timing of acquiring the state information of the PUCCH repetition enabling needs to be emphasized that the acquired state information of the PUCCH repetition enabling is invalid if the MAC CE is valid. The effective moment of the MAC CE is the moment when the terminal sends HARQ-ACK feedback to the base station after receiving the MAC CE and the base station receives the HARQ-ACK feedback.

Step 52: and if the state information is in an enabling state, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode.

Step 53: and if the state information is in a non-enabled state, the terminal determines the number of times of PUCCH repeated transmission by adopting a semi-static mode.

The method (a) further includes the following cases: and if the MAC CE is not effective, which is caused by the fact that the base station does not receive HARQ-ACK feedback sent by the terminal, the terminal determines the repeated transmission times in a dynamic mode or a semi-static mode.

In the sixth case: and if the target information is the control information carried in the DCI in the second target information, the terminal determines the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode based on the target information. As described in detail below, referring to fig. 9, the method specifically includes:

step 61: and the terminal acquires the state value of the PUCCH repetition indication domain in the DCI from the control information.

Because the base station configures the state values of the PUCCH repetition indication fields in the DCI in advance in the control information, and configures an indication action for each state value. Therefore, in the implementation process, the terminal needs to first acquire the state value of the PUCCH repetition indication field in the received DCI.

Step 62: and if the state value of the PUCCH repetition enabling indication domain is a preset first state value, the terminal determines the PUCCH repeated transmission times in a dynamic mode, wherein the first state value is used for indicating the terminal to determine the PUCCH repeated transmission times in the dynamic mode.

Based on the first state value (e.g. 1) pre-configured by the base station, based on the configuration of the base station, the terminal correspondingly determines the number of PUCCH retransmission times in a dynamic manner, for example, the number of PUCCH retransmission times may be determined in a manner indicated in the third column or the fourth column of table 1.

And step 63: and if the state value of the PUCCH repetition enabling indication domain is a preset second state value, the terminal determines the PUCCH repeated transmission times in a semi-static mode, wherein the second state value is used for indicating the terminal to determine the PUCCH repeated transmission times in the semi-static mode.

Likewise, based on the second state value (e.g. 0) pre-configured by the base station, based on the above configuration, in this case, the terminal correspondingly determines the PUCCH retransmission times in a semi-static manner, for example, the PUCCH retransmission times may be determined in a manner indicated in the second column of table 1.

The method (a) further includes the following cases: if the terminal does not acquire the state value of the PUCCH repetition indication domain in the DCI from the control information, which is caused by the fact that the base station does not configure the state value of the PUCCH repetition indication domain, the terminal determines the number of times of PUCCH repeated transmission by adopting a semi-static mode.

The following describes the case of base station side, i.e. the base station determines the number of repeated transmissions to distinguish between dynamic and semi-static. Referring to fig. 10, in the embodiment of the present disclosure, a specific process executed by the base station is as follows:

step 201: the base station generates target information, wherein the target information comprises first target information or second target information.

In the embodiment of the present application, in order to enable the terminal to adopt a dynamic mode or a semi-static mode through an optional mode and determine the number of times of PUCCH retransmission, the base station may configure a plurality of types of configuration information in a semi-static manner in advance through a high-level signaling and issue the configuration information to the terminal. It is emphasized that the following configuration information is a plurality of parameters selectable in parallel, and the terminal selects one of them (for example, BWP configuration information) when implementing, i.e. determines the number of PUCCH retransmission times.

Specifically, the first target information includes any one of: search Space configuration information, core set configuration information, or BWP configuration information, or PDCCH candidate or PDCCH MO packet information. The target information is high-level signaling semi-static configuration.

Correspondingly, in order to enable the terminal to distinguish and adopt a dynamic mode or a semi-static mode through an optional mode and determine the repeated transmission times of the PUCCH, the base station also sends various dynamic instructions in the communication process and sends the dynamic instructions to the terminal. Specifically, the second target information includes any one of: control information carried in the MAC CE or the DCI, so that the terminal selects one of them (e.g., control information carried in the DCI) to determine the number of repeated PUCCH transmissions when implemented.

It should be noted that, if the terminal determines the number of PUCCH retransmission times in a semi-static manner based on the target information, the number of retransmission times is at least one. That is, the case where the terminal determines the number of times of retransmission of the PUCCH in the semi-static manner includes at least a case where the number of times of retransmission is one, that is, a case where retransmission is not performed.

In an implementation process, the step 201 specifically includes the base station generating first target information, so that the terminal determines the number of times of PUCCH retransmission in a dynamic manner or a semi-static manner based on the first target information; or the base station generates second target information so that the terminal determines the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode based on the second target information.

The first target information is any one of Search Space configuration information, core set configuration information, BWP configuration information, PDCCH candidate packet information, and PDCCH MO packet information. The following describes the generation process of the first target information in detail in different cases, and specifically includes:

in the first case: the base station generates target information, specifically including:

referring to fig. 11, the first method:

step 111: the base station configures state information of PUCCH repetition enabling in Search Space configuration information, wherein the state information is an enabled state or a non-enabled state.

In order to enable the terminal to obtain the state information of the PUCCH repetition enabling in the Search Space configuration information, the base station needs to configure the state information of the PUCCH repetition enabling in the Search Space configuration information, specifically, the state information is configured to be an enabled state or a disabled state, where the enabled state and the disabled state are distinguished by different values, and the enabled state and the disabled state are usually 1 and the disabled state is 0.

Step 112: and the base station configures the represented indication action for the state information, wherein the indication action for enabling the state representation is as follows: the indication terminal adopts a dynamic mode to determine the repeated transmission times of the PUCCH, and the indication action of the non-enabled state representation is as follows: and indicating the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

After configuring the state information, the base station is required to configure a corresponding indication action, so that the terminal performs the corresponding action after receiving the state information. In the implementation process, the base station configures the indication action corresponding to the enabling state into the indication terminal to determine the repeated transmission times of the PUCCH in a dynamic mode; and configuring an indication action corresponding to the non-enabled state to indicate the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

Of course, the base station may also configure the indication action corresponding to the enabled state to indicate the terminal to determine the number of PUCCH retransmission times in a semi-static manner; and configuring the indication action corresponding to the enabling state into an indication terminal to determine the repeated transmission times of the PUCCH in a dynamic mode, thereby realizing flexible configuration.

In the implementation process, the base station configures the indication action corresponding to the enabling state into the indication terminal to determine the repeated transmission times of the PUCCH in a dynamic mode; the following describes an example in which the indication operation corresponding to the disabled state is configured to instruct the terminal to determine the number of times of PUCCH retransmission in a semi-static manner.

Step 113: the base station generates first target information based on the state information and the indication action of the PUCCH repetition enabling configured in the Search Space configuration information.

After configuring the state information and the indication action of the PUCCH repetition enabling in the Search Space configuration information, the base station generates first target information based on the state information and the indication action, and sends the first target information to the terminal to indicate the terminal to determine the number of times of PUCCH repeated transmission by adopting a dynamic mode or a semi-static mode.

In addition, this mode further includes: if the base station does not configure the state information of the PUCCH repetition enabling in the Search Space configuration information, in the mode, the terminal can be indicated by high-level signaling to determine the repeated transmission times of the PUCCH in a semi-static mode.

Referring to fig. 12, a second method:

step 111': the base station generates first configuration information based on a Search Space ID set configured in PUCCH resources.

In the implementation process, the base station additionally configures associated Search Space IDs for PUCCH resources indicated by the PRI domain, so as to obtain a Search Space ID set, and based on the configured Search Space ID set, the base station generates first configuration information.

Step 112': the base station configures the represented indication action for the first configuration information, and the indication action is as follows: and instructing the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode.

After configuring the first configuration information, the base station is required to configure a corresponding indication action, so that the terminal performs the corresponding action after receiving the state information. In the implementation process, the base station configures the indication action corresponding to the first configuration information into an indication terminal to determine the repeated transmission times of the PUCCH in a dynamic mode.

Correspondingly, if the Search Space ID in the Search Space configuration information acquired by the terminal does not belong to the Search Space ID set, the terminal is instructed to determine the number of times of PUCCH retransmission in a semi-static manner.

Step 113': the base station generates first target information based on the first configuration information and the indication action.

After configuring the first configuration information and the indication action, the base station generates first target information based on the first configuration information and the indication action, and sends the first target information to the terminal to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode.

In the second case: the base station generates target information, specifically including:

referring to fig. 13, in a first mode:

step 211: the base station configures the state information of the PUCCH repetition enabling in CORESET configuration information, wherein the state information is an enabling state or a non-enabling state.

In order to enable the terminal to obtain the state information of the PUCCH repetition enabling in the CORESET configuration information, the base station needs to configure the state information of the PUCCH repetition enabling in the CORESET configuration information, specifically, the state information is configured to be an enabled state or a disabled state, where the enabled state and the disabled state are distinguished by different values, and the enabled state and the disabled state are usually 1 and the disabled state is 0.

Step 212: and the base station configures the represented indication action for the state information, wherein the indication action for enabling the state representation is as follows: the indication terminal adopts a dynamic mode to determine the repeated transmission times of the PUCCH, and the indication action of the non-enabled state representation is as follows: and indicating the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

After configuring the state information, the base station is required to configure a corresponding indication action, so that the terminal performs the corresponding action after receiving the state information. In the implementation process, the base station configures the indication action corresponding to the enabling state into the indication terminal to determine the repeated transmission times of the PUCCH in a dynamic mode; and configuring the indication action corresponding to the non-enabled state to indicate the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

Of course, the base station may also configure the indication action corresponding to the enable state to indicate the terminal to determine the number of times of PUCCH retransmission in a semi-static manner; and configuring the indication action corresponding to the enabling state into an indication terminal to determine the repeated transmission times of the PUCCH in a dynamic mode, thereby realizing flexible configuration.

Step 213: and the base station generates first target information based on the state information and the indication action of the PUCCH repetition mechanism configured in the CORESET configuration information.

After configuring the state information and the indication action of the PUCCH repetition in the CORESET configuration information, the base station generates first target information based on the state information and the indication action so as to send the first target information to the terminal to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode.

Further, in this case, the method further includes: if the base station does not configure the state information of the PUCCH retransmission mechanism in the CORESET configuration information, in the mode, the terminal can be indicated by high-level signaling to determine the repeated transmission times of the PUCCH in a semi-static mode.

Referring to fig. 14, the second method:

step 211', the base station generates second configuration information based on the set of CORESET IDs configured in the PUCCH resources.

In the implementation process, the base station additionally configures a correlated CORESET ID for the PUCCH resource indicated by the PRI field in the DCI, so as to obtain a CORESET ID set, and the base station generates second configuration information based on the configured CORESET ID set.

Step 212', the base station configures the characterized indication action for the second configuration information, where the indication action is: and indicating the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode.

After configuring the second configuration information, the base station is required to configure a corresponding indication action, so that the terminal performs the corresponding action after receiving the status information. In the implementation process, the base station configures the indication action corresponding to the second configuration information into an indication terminal to determine the number of times of repeated transmission of the PUCCH in a dynamic mode.

Correspondingly, if the CORESET ID in the CORESET configuration information corresponding to the DCI acquired by the terminal does not belong to the CORESET ID set, the terminal is instructed to determine the PUCCH repeated transmission times in a semi-static mode.

Step 213' the base station generates the first target information based on the second configuration information and the indication action.

After configuring the second configuration information and the indication action, the base station generates first target information based on the second configuration information and the indication action, and sends the first target information to the terminal to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode.

In the third case: the base station generates the target information, as shown in fig. 15, specifically including:

step 311: the base station generates third configuration information based on the state information of the PUCCH repetition enabling in the BWP configuration information where the PUCCH channel is located, or the state information of the PUCCH repetition enabling in the BWP corresponding to the DCI, wherein the state information is an enabling state or a non-enabling state.

In one embodiment, in order to enable the terminal to acquire the state information of the PUCCH repetition enabling in the BWP configuration information of the PUCCH channel, the base station needs to configure the state information of the PUCCH repetition enabling in the BWP configuration information of the PUCCH channel, specifically, the state information is configured to be an enabled state or a disabled state, and the enabled state and the disabled state are flexibly distinguished by different values.

In another embodiment, in order to enable the terminal to acquire the state information of the PUCCH repetition enabling in the BWP corresponding to the DCI, the base station needs to configure the state information of the PUCCH repetition enabling in the BWP corresponding to the DCI, specifically, the state information is configured to be an enabled state or a disabled state, and the enabled state and the disabled state may be flexibly distinguished by different values.

Step 312: and the base station configures the represented indication action for the state information, wherein the indication action for enabling the state representation is as follows: the indication terminal adopts a dynamic mode to determine the repeated transmission times of the PUCCH, and the indication action of the non-enabled state representation is as follows: and indicating the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

In the implementation process, the base station configures the indication action corresponding to the enabling state into the indication terminal to determine the number of times of PUCCH repeated transmission in a dynamic mode; the following describes an example in which the indication operation corresponding to the disabled state is configured to instruct the terminal to determine the number of times of PUCCH retransmission in a semi-static manner.

Step 313: the base station generates first target information based on the state information and the indication action.

After configuring the state information of the PUCCH repetition enhancement in the BWP configuration information where the PUCCH channel is located, or the state information of the PUCCH repetition enhancement in the BWP corresponding to the DCI and the corresponding indication action, the base station generates first target information based on the state information and the indication action, and sends the first target information to the terminal to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode.

Further, in this case, the method further includes: if the base station does not configure the state information of the PUCCH retransmission enabling in the BWP configuration information where the PUCCH channel is located, or does not configure the state information of the PUCCH retransmission enabling in the BWP configuration information corresponding to the DCI, that is, if scheme 1 is the state information of the PUCCH retransmission enabling in the BWP configuration information where the PUCCH channel is not located by the base station, that is, if scheme 2 is the state information of the PUCCH retransmission enabling in the BWP configuration information corresponding to the DCI not located by the base station, the base station instructs the terminal to determine the number of times of PUCCH retransmission transmission in a semi-static manner in scheme 1 or scheme 2.

In a fourth case: the base station generates the target information, which is shown in fig. 16 and specifically includes:

step 411: and the base station configures a first target packet and a second target packet based on the position packet information, wherein the first target packet and the second target packet comprise the position packet information of the PDCCH candidate or the PDCCH MO.

In order for the terminal to determine which packet it belongs to based on the PDCCH candidate or PDCCH MO location information during implementation, the base station first allocates the first target packet and the second target packet based on the location packet information.

Step 412: the base station configures a characterized indicating action for the first target group, wherein the indicating action is as follows: and instructing the terminal to determine the number of repeated transmission of the PUCCH in a dynamic mode, wherein the first target packet comprises a PDCCH candidate set or a PDCCH MO set.

After the first target packet is obtained, the base station is required to configure a corresponding indication action, so that the terminal performs the corresponding action after receiving the state information. In the implementation process, the base station configures the indication action characterized by the first target packet into an indication action for indicating the terminal to determine the number of times of PUCCH repeated transmission in a dynamic mode.

It should be noted that the first target packet is a PDCCH candidate set, or the first target packet is a PDCCH MO set.

Step 413: and the base station configures a characterized indicating action for the second target group, wherein the indicating action is as follows: and instructing the terminal to determine the number of times of PUCCH repeated transmission in a semi-static manner, wherein the second target packet comprises a PDCCH candidate set or a PDCCH MO set.

After the second target packet is obtained, the base station is required to configure a corresponding indication action, so that the terminal performs the corresponding action after receiving the state information. In the implementation process, the base station configures the indication action characterized by the second target packet into an indication that the terminal determines the number of times of repeated transmission of the PUCCH in a semi-static manner.

It should be added that the second target packet is a PDCCH candidate set, or the second target packet is a PDCCH MO set.

Step 414: the base station generates first target information based on the first target packet, the second target packet, and the indication action.

After configuring the first target packet and the indication action, the base station generates first target information based on the first target packet and the indication action, and after configuring the second target packet and the indication action, the base station generates second target information based on the second target packet and the indication action, so as to send the second target information to the terminal to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode.

Further, in this case, the method further includes: and if the base station does not configure the first target grouping and the second target grouping, indicating the terminal to adopt a semi-static mode to determine the number of times of PUCCH repeated transmission.

In the implementation process, the grouping information is configured by adopting any one of the following modes:

1) Configured in the Search Space configuration information. In this case, the base station arranges packet information of PDCCH candidate in the Search Space allocation information, or the base station arranges packet information of PDCCH MO in the Search Space allocation information.

2) Configured in the PUCCH resource-related configuration information indicated by the PRI field in the DCI. In this case, the base station arranges the packet information of PDCCH candidate in the PUCCH resource-related arrangement information indicated by the PRI field in the DCI, or the base station arranges the packet information of PDCCH MO in the PUCCH resource-related arrangement information indicated by the PRI field in the DCI.

3) Configured according to a protocol predefined. In this case, the base station configures the packet of PDCCH candidate or PDCCH MO according to a predefined manner in the protocol.

It is considered that the indication in the second target information is any one of control information carried in the MAC CE or the DCI. The following is detailed in cases including:

in the fifth case: the base station generates the target information, as shown in fig. 17, specifically including:

step 511: the base station generates state information of PUCCH repetition enabling carried in the MAC CE, wherein the state information is in an enabling state or a non-enabling state.

In order to enable the terminal to obtain the state information of the PUCCH repetition enhancement carried in the MAC CE, the base station needs to first generate the state information of the PUCCH repetition enhancement carried in the MAC CE, specifically, the state information is an enabled state or a disabled state, and the enabled state and the disabled state are flexibly distinguished by different values.

Step 512: and the base station generates a represented indication action for the state information, wherein the indication action for enabling the state representation is as follows: the indication terminal adopts a dynamic mode to determine the repeated transmission times of the PUCCH, and the indication action of the non-enabled state representation is as follows: and indicating the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

After the status information is generated, the base station is required to generate a corresponding indication action, so that the terminal executes the corresponding action after receiving the status information. In the implementation process, the base station generates an indication action corresponding to the enabling state to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode; and generating an indication action corresponding to the non-enabled state to indicate the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

Of course, the base station may also generate an indication action corresponding to the enabled state to indicate the terminal to determine the number of times of PUCCH retransmission in a semi-static manner; and generating the indication action corresponding to the enabling state as an indication terminal to determine the repeated transmission times of the PUCCH in a dynamic mode, thereby realizing the flexible generation of the indication action.

In the implementation process, the base station generates an indication action corresponding to the enabling state to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode; the generation of the indication operation corresponding to the disabled state is described as an example of indicating the terminal to determine the number of times of PUCCH retransmission in a semi-static manner.

Step 513: the base station generates second target information based on the state information and the instruction action.

After generating the state information and the indication action of the PUCCH repetition enabling carried in the MAC CE, the base station generates first target information based on the state information and the indication action so as to send the first target information to the terminal to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode.

It should be added here that the validation time of the MAC CE is a time after the terminal receives the MAC CE and then sends HARQ-ACK feedback to the base station, and the base station receives the HARQ-ACK feedback.

In the above step, it is necessary to emphasize that the timing of acquiring the state information of the PUCCH retransmission mechanism is when the MAC CE is valid, otherwise, the acquired state information of the PUCCH retransmission mechanism is invalid. If the MAC CE received by the terminal is not effective, the base station sets default configuration to indicate the terminal to adopt a dynamic mode or a semi-static mode to determine the repeated transmission times.

In the sixth case: the base station generates the target information, as shown in fig. 18, specifically including:

step 611: the base station presets a first state value or a second state value for the PUCCH repetition enabling indication domain.

In the implementation process, the base station generates the state value of the PUCCH repetition indicating field in the DCI in advance, specifically including the first state value or the second state value. In general, the base station generates the first state value or the second state value in control information.

Step 612: and the base station generates a characterized indicating action for the first state value, wherein the indicating action is as follows: and the indication terminal determines the repeated transmission times of the PUCCH in a dynamic mode, the base station generates a represented indication action for the second state value, and the indication action is as follows: and indicating the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

After the first state value or the second state value is preset, the base station is required to generate a corresponding indication action, so that the terminal executes the corresponding action after receiving the state information. In the implementation process, the base station generates an indication action corresponding to the first state value to indicate the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode; and generating an indication action corresponding to the second state value to indicate the terminal to determine the repeated transmission times of the PUCCH in a semi-static mode.

Of course, the base station may also generate an indication action corresponding to the first state value to indicate the terminal to determine the number of times of PUCCH retransmission in a semi-static manner; and generating an indication action corresponding to the second state value as an indication terminal to determine the repeated transmission times of the PUCCH in a dynamic mode, thereby achieving the purpose of flexibly generating the state value.

Step 613: and the base station generates second target information based on the preset state value and the indication action of the PUCCH repetition indication domain.

After the first state value or the second state value is generated, the base station generates second target information based on the first state value, the second state value and the corresponding indication action, and sends the second target information to the terminal to indicate the terminal to determine the number of times of PUCCH repeated transmission in a dynamic mode or a semi-static mode.

Further, in this case, it further includes: if the base station does not generate the PUCCH repetition indication domain, in the mode, the terminal can be indicated by the high-level signaling to determine the repeated transmission times of the PUCCH in a semi-static mode.

Step 202: and the base station sends the target information to the terminal so that the terminal determines the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode based on the target information.

In the implementation process, after the base station generates the first target information and the second target information (namely, the target information), the base station sends the target information to the terminal, so that the terminal can determine the repeated transmission times of the PUCCH in a dynamic mode or a semi-static mode based on the target information. That is, the terminal determines the number of PUCCH retransmission times in a dynamic manner or a semi-static manner based on the first target information, or determines the number of PUCCH retransmission times in a dynamic manner or a semi-static manner based on the second target information.

The above embodiments are further described in detail below using several specific application scenarios.

Application scenario 1:

the base station configures 3 search spaces { #1, #2, #3} for the terminal, wherein a PUCCH repetition enabling configured in the search space #1 is in an enable state; the PUCCH repetition enabling configured in the search space #2 is in a disable state; the search space #3 does not have PUCCH repetition associating information configured.

Meanwhile, the base station configures an indication action for the state information of which the PUCCH repetition enabling is enabled, namely, the base station indicates the terminal to determine the repeated transmission times of the PUCCH in a dynamic mode. Similarly, the base station configures an indication action for the state information that the PUCCH repetition enabling is disabled, that is, instructs the terminal to determine the number of times of PUCCH retransmission in a semi-static manner.

Since the terminal determines the number of repeated transmissions in different manners under different PUCCH repetition periods, the base station needs to configure PUCCH resource sets corresponding to different search spaces in advance for the terminal, assuming that the PUCCH resource sets are as shown in table 1.

If the terminal receives a DCI scheduling Physical Downlink Shared Channel (PDSCH) in the search space #1, the PRI field in the DCI indicates the PUCCH resource and also indicates the number of repeated transmissions of the PUCCH. For example, the PRI field may determine the resources of the PUCCH and the corresponding number of repeated transmissions according to the third or fourth column configuration of table 1. At this time, the PRI field may indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions.

If the terminal receives DCI scheduling PDSCH in search space #2, the PRI field in the DCI is only used to indicate PUCCH resource according to the definition in Rel-15/16, in this case, the number of times of repeated transmission of PUCCH is determined by nrofslot configured in the higher layer parameter PUCCH-Config. For example, the PRI domain determines resources of the PUCCH according to the second column configuration of table 1. At this time, the PRI field may indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is determined by semi-static configuration.

If the terminal receives the DCI-scheduled PDSCH in search space #3, the PRI field in the DCI is used only to indicate PUCCH resources by default, the number of repeated transmission of the PUCCH is determined by nrofshift configured in the PUCCH-Config. For example, the PRI domain determines PUCCH resources according to the second column configuration of table 1.

In addition, if the configured PUCCH retransmission enabling information of the search space where the DCI transmission of the two scheduled PDSCHs is located is different, HARQ-ACK feedback corresponding to the PDSCH needs to be transmitted in different slots/sub-slots, so that the situation that the finally determined PUCCH resources and PUCCH repeat transmission times are different due to different sets of PUCCH resources corresponding to the two search spaces can be avoided.

Application scenario 2:

the base station configures 3 search spaces { #1, #2, #3} for the terminal. Wherein, the PUCCH repetition enabling configured in the search space #1 is in an enable state; the PUCCH repetition enabling configured in the search space #2 is in a disable state; the search space #3 does not have PUCCH repetition associating information configured.

In addition, when configuring the PUCCH resources, the base station additionally configures a Search Space ID set, namely a Search Space ID list { Search Space #1, search Space #2} in the PUCCH-Config. The base station configures PUCCH resource sets corresponding to different search spaces for the terminal in advance, assuming that the PUCCH resource sets are shown in table 1.

If the terminal receives the DCI scheduling PDSCH in the search space #1 and the search space #2, the PRI field in the DCI needs to indicate the number of repeated transmissions of the PUCCH while indicating the PUCCH resource. For example, the PRI field may determine the resources of the PUCCH and the corresponding number of repeated transmissions according to the third or fourth column configuration of table 1. At this time, the PRI field may indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions.

If the terminal receives DCI scheduling PDSCH in search space #3, the PRI field in the DCI is only used for indicating PUCCH resources according to the definition in Rel-15/16, in this case, the repeated transmission times of the PUCCH are determined by nrofshift configured in a higher layer parameter PUCCH-Config. For example, the PRI domain determines resources of the PUCCH according to the second column configuration of table 1. At this time, the PRI field may indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is semi-statically configured to be determined.

Additionally, if the PUCCH resource sets configured by the search space where the DCI transmission of the two scheduled PDSCHs are located are different, HARQ-ACK feedback corresponding to the PDSCH needs to be transmitted in different slots/sub-slots, so that the situation that the finally determined PUCCH resources and PUCCH repeat transmission times are different due to the different PUCCH resource sets corresponding to the two search spaces can be avoided.

Application scenario 3:

the base station configures 3 BWPs { #1, #2, #3}, wherein a PUCCH repetition enabling configured in BWP #1 is in an enable state; the PUCCH repetition enabling configured in BWP #2 is in a disable state; BWP #3 does not have PUCCH repetition associating information configured.

Meanwhile, the base station configures an indication action for the state information of which the PUCCH repetition enabling configured in the BWP is enable, that is, instructs the terminal to determine the number of times of PUCCH retransmission in a dynamic manner. Similarly, the base station configures an indication action for the state information that the PUCCH repetition enabling is disabled, that is, instructs the terminal to determine the number of times of PUCCH retransmission in a semi-static manner.

Since the terminal indicates the number of times of retransmission in different manners under different PUCCH retransmission enabling state information, the base station needs to configure PUCCH resource sets corresponding to different BWPs to the terminal in advance, assuming that the PUCCH resource sets are shown in table 1.

If the terminal receives DCI scheduling PDSCH transmitted on BWP #1, the PRI field in the DCI indicates the repeated transmission times of PUCCH while indicating the PUCCH resource. For example, the PRI field may determine the resources of the PUCCH and the corresponding number of repeated transmissions according to the third or fourth column configuration of table 1. At this time, the PRI field may indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions.

If the terminal receives DCI scheduling PDSCH transmitted on BWP #2, the PRI field in the DCI is only used to indicate PUCCH resources according to the definition in Rel-15/16, in this case, the number of repeated transmission of PUCCH is determined by nroftlat configured in PUCCH-Config. For example, the PRI domain determines resources of the PUCCH according to the second column configuration of table 1. At this time, the PRI field may indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is determined by semi-static configuration.

If the terminal receives DCI scheduling PDSCH sent on BWP #3, the PRI field in the DCI is only used for indicating PUCCH resources by default, and the nroftlot configured in the PUCCH-Config of the repeated transmission times of the PUCCH is determined. For example, the PRI domain determines PUCCH resources according to the second column configuration of table 1.

Similarly, since the terminal supports the uplink and downlink to work in different BWPs, the terminal behavior can also be determined according to the BWP index where the PUCCH channel indicated by the DCI is transmitted. If the PUCCH channel is transmitted on BWP #1, the PRI field in the DCI indicates the PUCCH resource and also needs to indicate the repeated transmission times of the PUCCH.

For example, the PRI field may determine the resources of the PUCCH and the corresponding number of repeated transmissions according to the third or fourth column configuration of table 1. At this time, the PRI field may indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions. If the PUCCH channel is transmitted on BWP #2, according to the definition in Rel-15/16, the PRI field in the DCI is only used for indicating PUCCH resources, and the repeated transmission number of the PUCCH is determined by nroftlat configured in the PUCCH-Config. For example, the PRI domain determines resources of the PUCCH according to the second column configuration of table 1. At this time, the PRI field may indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is determined by the higher layer signaling semi-static configuration.

If the PUCCH channel is transmitted on BWP #3, the PRI field in the DCI is only used for indicating PUCCH resources by default, and the repeated transmission number of the PUCCH is determined by nrofshift configured in PUCCH-Config. In this case, the PRI domain determines PUCCH resources according to the second column configuration of table 1.

Application scenario 4:

assuming that there are 8 PDCCH candidates in a search space, including PDCCH candidates indexes #0 to #3 with aggregation level 2, PDCCH candidates indexes #0 and #1 with aggregation level 4, and PDCCH candidates indexes #0 and #1 with aggregation level 8, the base station may group the PDCCH candidates.

In order not to affect the reliability of DCI, each set of PDCCH candidates should contain as many aggregation levels as possible. For example, indexes #0 and #1 of aggregation level 2, index #0 of aggregation level 4, and PDCCH candidate of index #1 of aggregation level 8 are first target packets, and indexes #2 and #3 of aggregation level 2, index #2 of aggregation level 4, and PDCCH candidate of index #2 of aggregation level 8 are second target packets. The base station may configure the packet list in the search space, and may also configure the packet list in the PUCCH resource. The base station needs to allocate PUCCH resource sets corresponding to different PDCCH candidate groups to the terminal in advance, which is assumed to be shown in table 1.

If the terminal receives a DCI scheduling PDSCH transmitted on one PDCCH candidate in the first target packet PDCCH candidates, the PRI field in the DCI needs to indicate the repeated transmission times of the PUCCH while indicating the PUCCH resources. For example, the PRI field may determine the resources of the PUCCH and the corresponding number of repeated transmissions according to the third or fourth column configuration of table 1. At this time, the PRI field may indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions.

If the terminal receives DCI scheduling PDSCH transmitted on one PDCCH candidate in the second target packet PDCCH candidates, the PRI field in the DCI is only used for indicating PUCCH resources according to the definition in Rel-15/16, and the repeated transmission times of the PUCCH are determined by nrofslot configured in the PUCCH-Config. For example, the PRI domain determines resources of the PUCCH according to the second column configuration of table 1. At this time, the PRI field may indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is determined by the higher layer signaling semi-static configuration.

In addition, if the PDCCH candidate groups where the DCI transmission of the two scheduled PDSCHs are located are different, the HARQ-ACK feedback corresponding to the PDSCH needs to be transmitted in different time slots/sub-time slots. So as to avoid the difference of the finally determined PUCCH and PUCCH repeated transmission times caused by the difference of the PUCCH resource sets corresponding to the two groups. In the implementation process, the position of the PDCCH candidate is determined through the CCE index indication, so that the PUCCH set corresponding to the packet of the PDCCH candidate is determined. However, if the number of resources in the resource set for PUCCH format 0/1 configured by the base station for the terminal exceeds 8 entries, the CCE index also needs to be combined to determine the final PUCCH resource in the prior art. At this time, the CCE index may not satisfy both indication requirements at the same time. Therefore, in this embodiment, the terminal does not expect the PUCCH resource set configured by the higher layer to exceed 8 entries.

Application scenario 5:

since the terminal indicates the number of times of retransmission in different manners under different PUCCH retransmission configurations, the base station needs to configure a PUCCH resource set corresponding to different PUCCH retransmission configuration information to the terminal in advance, assuming that the PUCCH resource set is as shown in table 1.

And after receiving the MAC CE transmitted by the base station through the PDSCH, the terminal acquires PUCCH repetition enabling related configuration information and feeds HARQ-ACK back to the base station. If the PUCCH repetition enabling is in an enable state, after the MAC CE takes effect, the PRI domain in the DCI received by the terminal needs to indicate the PUCCH resources and the repeated transmission times of the PUCCH. For example, the PRI field may determine the resources of the PUCCH and the corresponding number of repeated transmissions according to the third or fourth column configuration of table 1. At this time, the PRI field may indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions.

If the PUCCH retransmission enabling is in a disabled state, according to the definition in Rel-15/16, the PRI field in the DCI received by the terminal after the MAC CE takes effect is only used for indicating PUCCH resources, and the repeated transmission times of the PUCCH are determined by nrofshift configured in a high-layer parameter PUCCH-Config. For example, the PRI domain determines resources of the PUCCH according to the second column configuration of table 1. At this time, the PRI field may indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is determined by semi-static configuration. In the implementation process, the effective time of the current MAC CE needs to be after the base station receives the ACK fed back by the terminal.

When the MAC CE is not effective, the default PUCCH repetition enabling related configuration information can be in an enable state or a disable state.

Application scenario 6:

The terminal receives non-fallback DCI for dispatching the PDSCH, analyzes the DCI, and if the DCI does not have a PUCCH repetition enabling field, the PRI field in the DCI is only used for indicating PUCCH resources by default, and the repeated transmission times of the PUCCH are determined by nrofshift configured in a high-level parameter PUCCH-Config. For example, the PRI domain determines resources of the PUCCH according to the second column configuration of table 1. At this time, the PRI field may indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is determined by the higher layer signaling semi-static configuration. If a PUCCH repetition associating field is configured in DCI, when the field value is 0, the PRI field in the DCI needs to indicate a PUCCH resource and also needs to indicate the number of times of repeated transmission of the PUCCH. For example, the PRI field may determine the resources of the PUCCH and the corresponding number of repeated transmissions according to the third or fourth column configuration of table 1. At this time, the PRI field may indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions. Otherwise, when the domain value is 1, according to the definition in Rel-15/16, the PRI domain in the DCI is only used for indicating PUCCH resources, and the repeated transmission times of the PUCCH are determined by nroftlat configured in a high-layer parameter PUCCH-Config.
