Description

Technical Field

[0001] The present application relates to communication technology, and in particular to a method and device for determining the number of PUCCH retransmissions. Background Art

[0002] In the current 5th generation New Radio (5G) mobile communication system, during the research on 5G New Radio (NR) Physical Uplink Control Channel (PUCCH) coverage enhancement, a solution for dynamically indicating the number of PUCCH repetitions (repetition number) has been proposed. Specifically, there are two ways to dynamically indicate the PUCCH repetition number: implicit and explicit. In both of the above solutions, after configuring the repetition number, the base station needs to send and receive PUCCH according to the configured repetition number.

[0003] In the explicit indication mode, the number of PUCCH repetitions is independently configured. For example, using a 3-bit PUCCH Resource Indication (PRI) field and a 2-bit PUCCH repetition number field, the base station can indicate 32 different PUCCH resource repetitions (i.e., 8 PUCCH resource and 4 repetition number combinations).

[0004] In the implicit indication mode, since the same indication information carries more functions, the indication flexibility of the PUCCH resource is reduced when repetition is enabled.

[0005] For example, when the PRI domain needs to indicate both the PUCCH resource and the number of repetitions, if the base station configures four different repetitions for the same PUCCH resource, then the base station can use a 3-bit PUCCH resource to indicate eight different PUCCH resource repetitions (i.e., a combination of two PUCCH resources and four repetitions). In this case, when the channel conditions are good and PUCCH repetition is not required, the terminal can only select one of the two different PUCCH resources.

[0006] In summary, currently, if the base station instructs the terminal to dynamically determine the number of PUCCH repetition transmissions in an implicit manner, the flexibility of the base station in indicating PUCCH resources will be severely limited. Summary of the Invention

[0170] In order to enable ordinary people in the art to better understand the technical solutions disclosed in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0171] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0172] In current 5G mobile communication systems, and during research on PUCCH coverage enhancement for the 5G new air interface, after configuring the repetition number, the base station must transmit and receive PUCCH according to the configured repetition number. Specifically, there are two ways to dynamically indicate the PUCCH repetition number: implicit and explicit.

[0173] In the explicit indication mode, PUCCH resource selection and repetition number are configured independently. For example, when using a 3-bit PUCCH resource indication field and a 2-bit PUCCH repetition indication field, the base station can indicate 32 different PUCCH repetition transmission situations (i.e., including 8 PUCCH resource and 4 repetition number combinations).

[0174] In the implicit indication method, since the same indication information carries more functions, the indication flexibility is reduced when repetition is turned on. For example, when the PRI domain needs to indicate both the PUCCH resource and the number of repeated transmissions, if the base station configures four different numbers of repeated transmissions for the same PUCCH resource, then the base station can use a 3-bit PUCCH resource to indicate eight different PUCCH resource repeated transmission situations (i.e., a combination of two PUCCH resources and four numbers of repeated transmissions). In this case, when the channel conditions are good and PUCCH does not need to be transmitted repeatedly, the terminal can only select one of the two different PUCCH resources. In this way, the flexibility of resource indication is severely limited.

[0175] For example, when the number of PUCCH retransmissions is dynamically indicated by implicit indication, the high-level signaling configures an additional field for each PUCCH resource to indicate the dynamic number of retransmissions corresponding to the current PUCCH resource. Subsequently, the number of PUCCH retransmissions is implicitly indicated by reusing the existing bit field in the downlink control information (DCI). For example, the PRI field is used to simultaneously indicate the PUCCH transmission resource and the corresponding number of retransmissions. When the PRI field is used, the terminal first determines a PUCCH resource set based on the number of bits of the UCI to be transmitted (a resource set can contain multiple PUCCH resources), and then determines the specific PUCCH resource from the resource set through the PRI in the signaling. At the same time, the number of retransmissions of the PUCCH is determined based on the PRI.

[0176] When the implicit indication method of reusing the DCI field is used to dynamically indicate the number of PUCCH retransmissions, it is necessary to configure it through RRC parameters. After the configuration is completed, the base station and the terminal side need to send and receive PUCCH according to the currently configured number of retransmissions. Since the same indication information carries more functions, the flexibility of PUCCH resource indication is limited. When the channel conditions are good and there is no need to dynamically indicate the number of PUCCH retransmissions, or when only a small number of retransmissions are required, the available PUCCH resources are small, resulting in severe limitation of the flexibility of resource indication. Taking the 3-bit PRI field as an example, Table 1 gives the flexibility of PUCCH resource selection when the PRI field needs to indicate the number of PUCCH retransmissions and when it does not indicate the number of PUCCH retransmissions. When the PRI field is used to additionally indicate the number of PUCCH retransmissions, the number of optional PUCCH resources is significantly reduced.

[0180] The preferred embodiments of the present disclosure are further described in detail below with reference to the accompanying drawings.

[0181] In the embodiments of the present disclosure, the implementation of determining the number of PUCCH repetition transmissions is mainly divided into two aspects: the terminal side and the base station side, which are respectively introduced below.

[0182] Terminal side: After receiving the target information sent by the base station, the number of PUCCH retransmissions is determined dynamically or semi-statically. During the implementation process, the terminal determines the number of PUCCH retransmissions based on the target information, specifically the first target information or the second target information sent by the base station.

[0183] Base station side: Generate target information, specifically including first target information or second target information, to instruct the terminal to adopt a dynamic or semi-static method to determine the number of PUCCH repetition transmissions.

[0184] The following first introduces the situation where the terminal side determines the number of PUCCH repetition transmissions. Figure 1 As shown, in the embodiment of the present disclosure, the specific process of determining the number of PUCCH repetition transmissions is as follows:

[0185] Step 101: The terminal receives target information sent by a base station, where the target information includes first target information or second target information.

[0186] In the embodiments of the present application, in order to enable the terminal to determine the number of PUCCH retransmissions dynamically or semi-statically in an optional manner, the base station will pre-semi-statically configure multiple configuration information through high-layer signaling and send it to the terminal. It should be emphasized here that the following configuration information is a plurality of parameters that can be selected in parallel. During implementation, the terminal only needs to select one of them (for example, the BWP configuration information) to determine the number of PUCCH retransmissions.

[0187] Specifically, the first target information includes any one of the following: search space (SS) configuration information, control resource set (CORESET) configuration information or bandwidth slice (BandWidthPart, BWP) configuration information, or PDCCH candidate (PDCCH candidate) or monitoring occasion (MO) grouping information. The above target information is all semi-static configuration of high-layer signaling.

[0188] Accordingly, in order to enable the terminal to distinguish between dynamic and semi-static methods in an optional manner and determine the number of PUCCH retransmissions, the base station will also send multiple dynamic indications to the terminal during the communication process. Specifically, the second target information includes any one of the following: a Media Access Control (MAC) control element (CE) or control information carried in the DCI. During implementation, the terminal only needs to select one of the following (for example, the control information carried in the DCI) to determine the number of PUCCH retransmissions.

[0189] Step 102: The terminal determines the number of PUCCH repetition transmissions in a dynamic or semi-static manner based on the target information.

[0190] First, it should be noted that if the terminal semi-statically determines the number of PUCCH retransmissions based on target information, the number of retransmissions is at least one. That is, the case where the terminal semi-statically determines the number of PUCCH retransmissions includes at least one retransmission, i.e., no retransmissions are performed.

[0191] During implementation, the above step 102 specifically includes the terminal determining the number of PUCCH repetition transmissions dynamically or semi-statically based on the first target information; or, the terminal determining the number of PUCCH repetition transmissions dynamically or semi-statically based on the second target information.

[0192] Considering that the first target information is any one of Search Space configuration information, CORESET configuration information, BWP configuration information, PDCCH candidate grouping information, and PDCCH MO grouping information, the following details the terminal selecting one of the information to determine the number of PUCCH repetition transmissions, including:

[0193] Case 1: If the target information is the Search Space configuration information in the first target information, the terminal determines the number of PUCCH retransmissions dynamically or semi-statically based on the target information. The following two methods are described in detail, including:

[0194] See Figure 2 As shown, method one:

[0195] Step 11: The terminal obtains the status information of PUCCH repetition enabling in the Search Space configuration information.

[0196] Since the base station pre-configures PUCCH repetition enabling status information in the Search Space configuration information and configures an indication action for each status information, during implementation, the terminal needs to first obtain the PUCCH repetition enabling status information in the Search Space configuration information corresponding to the received DCI.

[0197] Step 12: If the status information indicates an enabled state, the terminal dynamically determines the number of PUCCH repetition transmissions.

[0198] Based on the pre-configuration of the base station, when the terminal determines that the received status information is an enabled state (for example, when the enabled state is enable), the number of PUCCH repeated transmissions is determined dynamically accordingly. For example, the number of PUCCH repeated transmissions can be determined according to the method indicated in the third or fourth column of Table 1.

[0199] Step 13: If the status information indicates a disabled state, the terminal determines the number of PUCCH repetition transmissions in a semi-static manner.

[0200] Similarly, based on the pre-configuration of the base station, when the terminal determines that the received status information is a non-enabled state (for example, when the enabled state is disable), in this case, the terminal parses the information field in the DCI according to the definition in the existing Rel-15 / 16, that is, the corresponding semi-static method is used to determine the number of PUCCH repeated transmissions. For example, the number of PUCCH repeated transmissions can be determined in the manner indicated in the second column of Table 1.

[0201] In addition, method 1 also includes the following situation: if the terminal does not obtain the status information of PUCCH repetition enabling in the Search Space configuration information, this situation is caused by the base station not configuring the status information of PUCCH repetition enabling in the Search Space configuration information. The terminal uses a semi-static method to determine the number of PUCCH repeated transmissions.

[0202] See Figure 3 As shown, method 2:

[0203] Step 11': The terminal receives the first configuration information, obtains a SearchSpace ID according to the SearchSpace configuration information, and determines a first association relationship between the SearchSpace ID and the first configuration information, wherein the first configuration information at least includes a SearchSpace ID set configured in the PUCCH resource, and the SearchSpace ID set indicates that the terminal is allowed to dynamically determine the number of PUCCH retransmissions.

[0204] Since the base station generates the first configuration information based on the Search Space ID set in advance, and configures an instruction action corresponding to the first configuration information, so as to instruct the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner.

[0205] Therefore, during implementation, the terminal needs to first obtain the Search Space ID in the Search Space configuration information. Accordingly, the first configuration information obtained by the terminal indicates that the number of PUCCH repetition transmissions is determined dynamically.

[0206] In order to further determine the method for 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 obtains a first association relationship between the Search Space ID and the first configuration information.

[0207] Step 12': If the first association relationship indicates that the first configuration information includes the Search Space ID, the terminal dynamically determines the number of PUCCH repetition transmissions.

[0208] During implementation, if the first configuration information includes the Search Space ID in the Search Space configuration information pre-acquired by the terminal, that is, the first association relationship indicates that the first configuration information includes the Search Space ID, then the terminal dynamically determines the number of PUCCH repetition transmissions.

[0209] Step 13': If the first association relationship indicates that the first configuration information does not include the Search Space ID, the terminal determines the number of PUCCH repetition transmissions in a semi-static manner.

[0210] During implementation, if the first configuration information does not include the Search Space ID in the Search Space configuration information pre-acquired by the terminal, that is, the first association relationship indicates that the first configuration information does not include the Search Space ID, then the terminal determines the number of PUCCH repetition transmissions in a semi-static manner.

[0211] In addition, the second method also includes the following situation: if the terminal does not receive the first configuration information, which is caused by the base station not configuring the above-mentioned first configuration information, the terminal uses a semi-static method to determine the number of PUCCH repetition transmissions.

[0212] The second case: If the target information is the CORESET configuration information in the first target information, the terminal determines the number of PUCCH retransmissions dynamically or semi-statically based on the target information. The following two methods are described in detail, including:

[0213] See Figure 4 As shown, method (1):

[0214] Step 21: The terminal obtains the status information of PUCCH repetition enabling in the CORESET configuration information.

[0215] Since the base station pre-configures the PUCCH repetition enabling status information in the CORESET configuration information and configures an indication action for each status information, during implementation, the terminal needs to first obtain the PUCCH repetition enabling status information in the CORESET configuration information corresponding to the received DCI.

[0216] Step 22: If the status information indicates an enabled state, the terminal dynamically determines the number of PUCCH repetition transmissions.

[0217] Based on the pre-configuration of the base station, when the terminal determines that the received status information is an enabled state (for example, when the enabled state is enable), the number of PUCCH repeated transmissions is determined dynamically accordingly. For example, the number of PUCCH repeated transmissions can be determined according to the method indicated in the third or fourth column of Table 1.

[0218] Step 23: If the status information indicates a disabled state, the terminal determines the number of PUCCH repetition transmissions in a semi-static manner.

[0219] Similarly, based on the pre-configuration of the base station, when the terminal determines that the received status information is a non-enabled state (for example, when the enabled state is disable), in this case, the terminal parses the information field in the DCI according to the definition in the existing Rel-15 / 16, that is, the corresponding semi-static method is used to determine the number of PUCCH repeated transmissions. For example, the number of PUCCH repeated transmissions can be determined in the manner indicated in the second column of Table 1.

[0220] In addition, method (1) also includes the following situation: if the terminal does not obtain the status information of PUCCH repetition enabling in the CORESET configuration information, this situation is caused by the base station not configuring the status information of PUCCH repetition enabling in the CORESET configuration information, then the terminal uses a semi-static method to determine the number of PUCCH repeated transmissions.

[0221] See Figure 5 As shown, method (2):

[0222] Step 21': The terminal receives the second configuration information, obtains 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 includes a CORESET ID set configured in the PUCCH resource, and the CORESET ID set indicates that the terminal is allowed to determine the number of PUCCH retransmissions in a dynamic manner.

[0223] Since the base station generates the second configuration information based on the CORESET ID set in advance, and configures an instruction action corresponding to the second configuration information, so as to instruct the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner.

[0224] Therefore, during implementation, the terminal needs to first obtain the CORESETID in the CORESET configuration information where the DCI is transmitted. Correspondingly, the second configuration information obtained by the terminal represents that the number of PUCCH repetition transmissions is determined in a dynamic manner.

[0225] In order to further determine the method for determining the number of repeated transmissions corresponding to the associated CORESET ID additionally configured for the PUCCH resource indicated by the PRI field in the DCI, the terminal obtains a second association relationship between the CORESET ID and the first configuration information.

[0226] Step 22 ′: If the second association relationship indicates that the second configuration information includes a CORESET ID, the terminal determines the number of PUCCH repetition transmissions in a dynamic manner.

[0227] During implementation, if the second configuration information includes the CORESET ID in the CORESET configuration information pre-acquired by the terminal, that is, the second association relationship indicates that the second configuration information includes the CORESET ID, then the terminal determines the number of PUCCH repetition transmissions in a dynamic manner.

[0228] Step 23 ′: If the second association relationship indicates that the second configuration information does not include a CORESET ID, the terminal determines the number of PUCCH repetition transmissions in a semi-static manner.

[0229] During implementation, if the second configuration information does not include the CORESET ID in the CORESET configuration information pre-acquired by the terminal, that is, the first association relationship indicates that the second configuration information does not include the CORESET ID, then the terminal determines the number of PUCCH repetition transmissions in a semi-static manner.

[0230] In addition, method (1) also includes the following situation: if the terminal does not receive the second configuration information, which is caused by the base station not configuring the above-mentioned second configuration information, the terminal uses a semi-static method to determine the number of PUCCH retransmissions.

[0231] The third case: If the target information is the BWP configuration information in the first target information, the terminal determines the number of PUCCH retransmissions dynamically or semi-statically based on the target information. Figure 6 As shown, specifically including:

[0232] Step 31: The terminal obtains third configuration information according to the BWP configuration information, wherein the third configuration information is status information of PUCCH repetition enabling in the BWP where the PUCCH channel is located, or status information of PUCCH repetition enabling in the BWP corresponding to the DCI.

[0233] Since the base station has pre-configured the PUCCH repetition enabling status information in the BWP where the PUCCH channel is located and configured an indication action for each status information; or the base station has pre-configured the PUCCH repetition enabling status information in the BWP corresponding to the DCI and configured an indication action for each status information. Therefore, during implementation, the terminal needs to first obtain the third configuration information, that is, the PUCCH repetition enabling status information in the BWP where the PUCCH channel is located, or the PUCCH repetition enabling status information in the BWP corresponding to the DCI.

[0234] Step 32: If the status information indicates an enabled state, the terminal dynamically determines the number of PUCCH repetition transmissions.

[0235] Based on the pre-configuration of the base station, when the terminal determines that the received status information is an enabled state (for example, when the enabled state is enable), the number of PUCCH repeated transmissions is determined dynamically accordingly. For example, the number of PUCCH repeated transmissions can be determined according to the method indicated in the third or fourth column of Table 1.

[0236] Step 33: If the status information indicates a disabled state, the terminal determines the number of PUCCH repetition transmissions in a semi-static manner.

[0237] Similarly, based on the pre-configuration of the base station, when the terminal determines that the received status information is a non-enabled state (for example, when the enabled state is disable), in this case, the terminal parses the information field in the DCI according to the definition in the existing Rel-15 / 16, that is, the corresponding semi-static method is used to determine the number of PUCCH repeated transmissions. For example, the number of PUCCH repeated transmissions can be determined in the manner indicated in the second column of Table 1.

[0238] In addition, method (1) also includes the following situation: if the terminal fails to successfully obtain the third configuration information, this situation is because the base station has not configured the status information of PUCCH repetition enabling in the BWP where the above-mentioned PUCCH channel is located, and the status information of PUCCH repetition enabling in the BWP corresponding to the DCI, then the terminal uses a semi-static method to determine the number of PUCCH repeated transmissions.

[0239] Fourth case: If the target information is the grouping information of the PDCCH candidate or PDCCH MO in the first target information, the terminal determines the number of PUCCH repetition transmissions dynamically or semi-statically based on the target information. Figure 7 As shown, specifically including:

[0240] Step 41: The terminal obtains the location information of the PDCCH candidate or PDCCH MO.

[0241] During implementation, in order to match the PDCCH candidate group corresponding to the received DCI to which group it belongs, the terminal first needs to obtain the position information of the PDCCH candidate or PDCCH MO from its own attributes. Generally, the above position information is represented in the form of an index.

[0242] Step 42: The terminal obtains the first target group and the second target group according to the grouping information, wherein the first target group and the second target group both include the position grouping information of the PDCCH candidates or the position grouping information of the PDCCH MO.

[0243] Since the base station pre-configures the first target group and the second target group based on the location group information and configures an instruction action for each target group, during implementation, the terminal needs to first obtain the first target group and the second target group based on the group information.

[0244] It should be noted that the above-mentioned first target group and second target group both include the position grouping information of the PDCCH candidate or the position grouping information of the PDCCH MO, that is, the basis for dividing the first target group and the second target group can be the position grouping information of the PDCCH candidate or the position grouping information of the PDCCH MO.

[0245] During implementation, how to determine the number of PUCCH repetition transmissions based on the PDCCH candidate group corresponding to the DCI received by the terminal requires matching the position information with the first target group or the second target group one by one.

[0246] Step 43: If the location information matches the first target group, the terminal dynamically determines the number of PUCCH retransmissions, where the first target group is pre-set, indicating that the terminal dynamically determines the PDCCH candidate set or PDCCH MO set for the number of PUCCH retransmissions.

[0247] Specifically, if the above position information matches the first target group, no matter the type of the first target group is a PDCCH candidate set or a PDCCH MO set, the terminal will dynamically determine the number of PUCCH repetition transmissions according to the preset setting of the base station.

[0248] Step 44: If the location information matches the second target group, the terminal uses a semi-static method to determine the number of PUCCH repetition transmissions, where the second target group is pre-set, indicating that the terminal uses a semi-static method to determine the PDCCH candidate set or PDCCH MO set for the number of PUCCH repetition transmissions.

[0249] Specifically, if the above position information matches the second target group, no matter the type of the second target group is a PDCCH candidate set or a PDCCH MO set, the terminal will determine the number of PUCCH repetition transmissions in a semi-static manner according to the preset of the base station.

[0250] In addition, mode (1) also includes the following situation: if the terminal does not receive the grouping information, which is caused by the base station not configuring the grouping information, the terminal uses a semi-static method to determine the number of PUCCH retransmissions.

[0251] It should be noted that the grouping information is obtained in any of the following ways:

[0252] (1) Obtained from Search Space configuration information. In this case, the terminal obtains the search space configuration information and determines the grouping of PDCCH candidates or PDCCH MOs based on the grouping information included in the relevant configuration information.

[0253] (2) Obtained from the PUCCH resource-related configuration information indicated by the PRI field in the DCI. In this case, the terminal determines the grouping of PDCCH candidates or PDCCH MOs based on the grouping information included in the PUCCH resource-related configuration information indicated by the PRI field in the DCI.

[0254] (3) Acquired according to protocol pre-definition: In this case, the terminal determines the grouping of PDCCH candidates or PDCCH MOs according to the grouping method pre-defined in the protocol.

[0255] Considering that the indication in the second target information is any one of the control information carried in the MAC CE or the DCI, the following is a detailed description of each case, specifically including:

[0256] The fifth case: If the target information is the MAC CE in the second target information, the terminal determines the number of PUCCH retransmissions dynamically or semi-statically based on the target information. Figure 8 As shown, specifically including:

[0257] Step 51: When the MAC CE takes effect, the terminal obtains the status information of PUCCH repetition enabling carried in the MAC CE.

[0258] Since the base station pre-configures the PUCCH repetition enabling status information in the MAC CE and configures an indication action for each status information, during implementation, the terminal needs to first obtain the PUCCH repetition enabling status information in the CORESET configuration information corresponding to the received DCI.

[0259] In this step, it is important to emphasize that the timing for obtaining the above-mentioned PUCCH repetition enabling status information is when the MAC CE takes effect. Otherwise, the obtained PUCCH repetition enabling status information is invalid. The above-mentioned MAC CE takes effect 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.

[0260] Step 52: If the status information indicates an enabled state, the terminal dynamically determines the number of PUCCH repetition transmissions.

[0261] Based on the pre-configuration of the base station, when the terminal determines that the received status information is an enabled state (for example, when the enabled state is enable), the number of PUCCH repeated transmissions is determined dynamically accordingly. For example, the number of PUCCH repeated transmissions can be determined according to the method indicated in the third or fourth column of Table 1.

[0262] Step 53: If the status information indicates a disabled state, the terminal determines the number of PUCCH repetition transmissions in a semi-static manner.

[0263] Similarly, based on the pre-configuration of the base station, when the terminal determines that the received status information is a non-enabled state (for example, when the enabled state is disable), in this case, the terminal parses the information field in the DCI according to the definition in the existing Rel-15 / 16, that is, the corresponding semi-static method is used to determine the number of PUCCH repeated transmissions. For example, the number of PUCCH repeated transmissions can be determined in the manner indicated in the second column of Table 1.

[0264] In addition, method (1) also includes the following situation: if MAC CE is not effective, this situation is caused by the base station not receiving the HARQ-ACK feedback sent by the terminal, then the terminal uses a dynamic method or a semi-static method to determine the number of repeated transmissions.

[0265] The sixth case: If the target information is the control information carried in the DCI in the second target information, the terminal determines the number of PUCCH retransmissions dynamically or semi-statically based on the target information. Figure 9 As shown, specifically including:

[0266] Step 61: The terminal obtains the status value of the PUCCH repetition enabling indication field in the DCI from the control information.

[0267] Since the base station pre-configures the state value of the PUCCH repetition enabling indication field in the DCI in the control information and configures the indication action corresponding to each state value, during the implementation process, the terminal needs to first obtain the state value of the PUCCH repetition enabling indication field in the received DCI.

[0268] Step 62: If the state value of the PUCCH repetition enabling indication field is a preset first state value, the terminal dynamically determines the number of PUCCH repetition transmissions, wherein the first state value is used to instruct the terminal to dynamically determine the number of PUCCH repetition transmissions.

[0269] Based on the first state value (for example, 1) pre-configured by the base station and based on the configuration of the base station, the terminal dynamically determines the number of PUCCH retransmissions. For example, the number of PUCCH retransmissions can be determined in accordance with the method indicated in the third or fourth column of Table 1.

[0270] Step 63: If the state value of the PUCCH repetition enabling indication field is a preset second state value, the terminal determines the number of PUCCH repetition transmissions in a semi-static manner, wherein the second state value is used to instruct the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0271] Similarly, based on the second state value (for example, 0) pre-configured by the base station and based on the above configuration, in this case, the terminal correspondingly adopts a semi-static method to determine the number of PUCCH repeated transmissions. For example, the number of PUCCH repeated transmissions can be determined in accordance with the method indicated in the second column of Table 1.

[0272] In addition, method (1) also includes the following situation: if the terminal does not obtain the status value of the PUCCHrepetition enabling indication field in the DCI from the control information, this situation is caused by the base station not configuring the status value of the above-mentioned PUCCHrepetition enabling indication field, then the terminal uses a semi-static method to determine the number of PUCCH repetition transmissions.

[0273] The following describes the situation where the base station determines the number of repeated transmissions dynamically or semi-statically. Figure 10 As shown, in the embodiment of the present disclosure, the specific process executed by the base station is as follows:

[0274] Step 201: The base station generates target information, where the target information includes first target information or second target information.

[0275] In the embodiment of the present application, in order to enable the terminal to determine the number of PUCCH retransmissions in a dynamic or semi-static manner in an optional manner, the base station will pre-configure multiple configuration information semi-statically through high-layer signaling and send it to the terminal. It should be emphasized here that the following configuration information is a plurality of parameters that can be selected in parallel. The terminal can determine the number of PUCCH retransmissions by selecting one of them (for example, BWP configuration information) during implementation.

[0276] Specifically, the first target information includes any one of the following: Search Space configuration information, CORESET configuration information, or BWP configuration information, or grouping information of PDCCH candidates or PDCCH MO. The above target information is all semi-statically configured by high-layer signaling.

[0277] Accordingly, in order to enable the terminal to distinguish between a dynamic method and a semi-static method in an optional manner to determine the number of PUCCH retransmissions, the base station will also send multiple dynamic indications to the terminal during the communication process. Specifically, the second target information includes any one of the following: MAC CE or control information carried in DCI, so that the terminal selects one of them (for example, the control information carried in DCI) to determine the number of PUCCH retransmissions during implementation.

[0278] It should be noted that if the terminal determines the number of PUCCH retransmissions in a semi-static manner based on target information, the number of retransmissions is at least one. That is, the case where the terminal determines the number of PUCCH retransmissions in a semi-static manner includes at least one case where the number of retransmissions is one, i.e., no retransmissions are performed.

[0279] During the implementation process, the above-mentioned step 201 specifically includes the base station generating first target information so that the terminal determines the number of PUCCH repeated transmissions dynamically or semi-statically based on the first target information; or, the base station generates second target information so that the terminal determines the number of PUCCH repeated transmissions dynamically or semi-statically based on the second target information.

[0280] Considering that the first target information is any one of Search Space configuration information, CORESET configuration information, BWP configuration information, PDCCH candidate grouping information, and PDCCH MO grouping information, the following describes the generation process of the first target information in detail, specifically including:

[0281] Case 1: The base station generates target information, including:

[0282] See Figure 11 As shown, method one:

[0283] Step 111: The base station configures the state information of PUCCH repetition enabling in the Search Space configuration information, where the state information is an enabling state or a disabling state.

[0284] In order for the terminal to obtain the status information of PUCCH repetition enabling in the Search Space configuration information, the base station needs to first configure the status information of PUCCH repetition enabling in the Search Space configuration information. Specifically, the above status information is configured as an enabled state or a disabled state. The enabled state and disabled state here can be distinguished by different values. Commonly, the enabled state is 1 and the disabled state is 0.

[0285] Step 112: The base station configures an indication action for the status information characterization, wherein the indication action for enabling the status characterization is: instructing the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner, and the indication action for disabling the status characterization is: instructing the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0286] After configuring the status information, the base station needs to configure the corresponding instruction action so that the terminal can perform the corresponding action after receiving the status information. During implementation, the base station configures the instruction action corresponding to the enabled state to instruct the terminal to dynamically determine the number of PUCCH retransmissions; and configures the instruction action corresponding to the disabled state to instruct the terminal to semi-statically determine the number of PUCCH retransmissions.

[0287] Of course, the base station can also configure the indication action corresponding to the enabled state to instruct the terminal to determine the number of PUCCH repeated transmissions in a semi-static manner; configure the indication action corresponding to the enabled state to instruct the terminal to determine the number of PUCCH repeated transmissions in a dynamic manner, thereby achieving flexible configuration.

[0288] During the implementation process, the base station configures the indication action corresponding to the enabled state to instruct the terminal to dynamically determine the number of PUCCH retransmissions; and configures the indication action corresponding to the disabled state to instruct the terminal to semi-statically determine the number of PUCCH retransmissions as an example for explanation.

[0289] Step 113: The base station generates first target information based on the state information and instruction action of PUCCH repetition enabling configured in the Search Space configuration information.

[0290] After configuring the status information and indication action of PUCCH repetition enabling in the Search Space configuration information, the base station generates first target information based on the above status information and indication action, and sends it to the terminal to instruct the terminal to determine the number of PUCCH repetition transmissions in a dynamic or semi-static manner.

[0291] In addition, this method also includes: if the base station does not configure the state information of PUCCH repetition enabling in the Search Space configuration information, in this method, the terminal can be instructed by high-layer signaling to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0292] See Figure 12 As shown, method 2:

[0293] Step 111 ′: The base station generates first configuration information based on the Search Space ID set configured in the PUCCH resources.

[0294] During implementation, the base station additionally configures an associated Search Space ID for the PUCCH resource indicated by the PRI domain, thereby obtaining a Search Space ID set. Based on the configured Search Space ID set, the base station generates first configuration information.

[0295] Step 112': the base station configures an indication action represented by the first configuration information, where the indication action is: instructing the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner.

[0296] After configuring the first configuration information, the base station needs to configure the corresponding instruction action so that the terminal can perform the corresponding action after receiving the status information. During implementation, the base station configures the instruction action corresponding to the first configuration information to instruct the terminal to dynamically determine the number of PUCCH retransmissions.

[0297] Correspondingly, if the Search Space ID in the Search Space configuration information acquired by the terminal does not belong to the above Search Space ID set, the terminal is instructed to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0298] Step 113 ′: The base station generates first target information based on the first configuration information and the instruction action.

[0299] After configuring the first configuration information and the instruction action, the base station generates first target information based on the first configuration information and the instruction action, and sends the first target information to the terminal to instruct the terminal to determine the number of PUCCH repetition transmissions in a dynamic or semi-static manner.

[0300] The second scenario: The base station generates target information, including:

[0301] See Figure 13 As shown, method one:

[0302] Step 211: The base station configures the state information of PUCCH repetition enabling in the CORESET configuration information, where the state information is an enabling state or a disabling state.

[0303] In order for the terminal to obtain the status information of PUCCH repetition enabling in the CORESET configuration information, the base station needs to first configure the status information of PUCCH repetition enabling in the CORESET configuration information. Specifically, the above status information is configured as an enabled state or a disabled state. The enabled state and disabled state are distinguished by different values. Commonly, the enabled state is 1 and the disabled state is 0.

[0304] Step 212: The base station configures an indication action for the status information characterization, wherein the indication action for enabling the status characterization is: instructing the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner, and the indication action for disabling the status characterization is: instructing the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0305] After configuring the status information, the base station needs to configure the corresponding instruction action so that the terminal can perform the corresponding action after receiving the status information. During implementation, the base station configures the instruction action corresponding to the enabled state to instruct the terminal to dynamically determine the number of PUCCH retransmissions; and configures the instruction action corresponding to the disabled state to instruct the terminal to semi-statically determine the number of PUCCH retransmissions.

[0306] Of course, the base station can also configure the indication action corresponding to the enabled state to instruct the terminal to determine the number of PUCCH repeated transmissions in a semi-static manner; configure the indication action corresponding to the enabled state to instruct the terminal to determine the number of PUCCH repeated transmissions in a dynamic manner, thereby achieving flexible configuration.

[0307] During the implementation process, the base station configures the indication action corresponding to the enabled state to instruct the terminal to dynamically determine the number of PUCCH retransmissions; and configures the indication action corresponding to the disabled state to instruct the terminal to semi-statically determine the number of PUCCH retransmissions as an example for explanation.

[0308] Step 213: The base station generates first target information based on the state information and instruction action of PUCCH repetition enabling configured in the CORESET configuration information.

[0309] After configuring the status information and indication action of PUCCH repetition enabling in the CORESET configuration information, the base station generates first target information based on the above status information and indication action, and sends it to the terminal to instruct the terminal to determine the number of PUCCH repetition transmissions in a dynamic or semi-static manner.

[0310] In addition, this situation also includes: if the base station does not configure the PUCCH repetition enabling status information in the CORESET configuration information, in this mode, the terminal can be instructed by high-layer signaling to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0311] See Figure 14 As shown, method 2:

[0312] Step 211': The base station generates second configuration information based on the CORESET ID set configured in the PUCCH resource.

[0313] During implementation, the base station additionally configures an associated CORESET ID for the PUCCH resource indicated by the PRI field in the DCI, thereby obtaining a CORESET ID set. Based on the configured CORESET ID set, the base station generates second configuration information.

[0314] Step 212': The base station configures an indication action representing the second configuration information, where the indication action is: instructing the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner.

[0315] After configuring the second configuration information, the base station needs to configure the corresponding instruction action so that the terminal can perform the corresponding action after receiving the status information. During implementation, the base station configures the instruction action corresponding to the second configuration information to instruct the terminal to dynamically determine the number of PUCCH retransmissions.

[0316] Correspondingly, if the CORESET ID in the CORESET configuration information corresponding to the DCI acquired by the terminal does not belong to the above CORESET ID set, the terminal is instructed to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0317] Step 213 ′: The base station generates first target information based on the second configuration information and the instruction action.

[0318] 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 instruct the terminal to determine the number of PUCCH repetition transmissions in a dynamic or semi-static manner.

[0319] The third case: The base station generates target information, see Figure 15 As shown, specifically including:

[0320] Step 311: The base station generates third configuration information based on the PUCCH repetition enabling status information in the BWP configuration information where the PUCCH channel is located, or the PUCCH repetition enabling status information in the BWP corresponding to the DCI, where the status information is enabled or disabled.

[0321] In one embodiment, in order for the terminal to obtain the status information of PUCCH repetition enabling in the BWP configuration information where the PUCCH channel is located, the base station needs to first configure the status information of PUCCH repetition enabling in the BWP configuration information where the PUCCH channel is located. Specifically, the above status information is configured as an enabled state or a disabled state, and the enabled state and the disabled state here can be flexibly distinguished by different numerical values.

[0322] In another embodiment, in order for the terminal to obtain the status information of PUCCH repetition enabling in the BWP corresponding to the DCI, the base station needs to first configure the status information of PUCCH repetition enabling in the BWP corresponding to the DCI. Specifically, the above status information is configured as an enabled state or a disabled state, and the enabled state and the disabled state here can be flexibly distinguished by different numerical values.

[0323] Step 312: The base station configures an indication action for the status information characterization, wherein the indication action for the enabled status characterization is: instructing the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner, and the indication action for the disabled status characterization is: instructing the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0324] After configuring the status information, the base station needs to configure the corresponding instruction action so that the terminal can perform the corresponding action after receiving the status information. During implementation, the base station configures the instruction action corresponding to the enabled state to instruct the terminal to dynamically determine the number of PUCCH retransmissions; and configures the instruction action corresponding to the disabled state to instruct the terminal to semi-statically determine the number of PUCCH retransmissions.

[0325] Of course, the base station can also configure the indication action corresponding to the enabled state to instruct the terminal to determine the number of PUCCH repeated transmissions in a semi-static manner; configure the indication action corresponding to the enabled state to instruct the terminal to determine the number of PUCCH repeated transmissions in a dynamic manner, thereby achieving flexible configuration.

[0326] During the implementation process, the base station configures the indication action corresponding to the enabled state to instruct the terminal to dynamically determine the number of PUCCH retransmissions; and configures the indication action corresponding to the disabled state to instruct the terminal to semi-statically determine the number of PUCCH retransmissions as an example for explanation.

[0327] Step 313: The base station generates first target information based on the state information and the instruction action.

[0328] After configuring the status information of PUCCH repetition enabling in the BWP configuration information where the PUCCH channel is located, or the status information of PUCCH repetition enabling in the BWP corresponding to the DCI and the corresponding indication action, the base station generates the first target information based on the above status information and indication action, and sends it to the terminal to instruct the terminal to determine the number of PUCCH repetition transmissions dynamically or semi-statically.

[0329] In addition, this situation also includes: if the base station does not configure the status information of PUCCH repetition enabling in the BWP configuration information where the PUCCH channel is located, or does not configure the status information of PUCCH repetition enabling in the BWP configuration information corresponding to the DCI, that is, Scheme 1 is that the base station does not configure the status information of PUCCH repetition enabling in the BWP configuration information where the PUCCH channel is located, that is, Scheme 2 is that the base station does not configure the status information of PUCCH repetition enabling in the BWP configuration information corresponding to the DCI. In the above Scheme 1 or Scheme 2, the base station instructs the terminal to use a semi-static method to determine the number of PUCCH repeated transmissions.

[0330] The fourth case: the base station generates target information, see Figure 16 As shown, specifically including:

[0331] Step 411: The base station configures a first target group and a second target group based on the position grouping information, wherein the first target group and the second target group include the position grouping information of the PDCCH candidate or the PDCCH MO.

[0332] During the implementation process, in order for the terminal to determine which group it belongs to based on the position information of the PDCCH candidate or PDCCH MO, the base station must first configure the first target group and the second target group based on the position group information. Therefore, during the implementation process, the base station needs to first obtain the first target group and the second target group based on the position group information of the PDCCH candidate or PDCCH MO.

[0333] Step 412: The base station configures a characterizing indication action for the first target group, where the indication action is: instructing the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner, wherein the first target group includes a PDCCH candidate set or a PDCCHMO set.

[0334] After obtaining the first target group, the base station needs to configure the corresponding indication action so that the terminal can perform the corresponding action after receiving the status information. During implementation, the base station configures the indication action represented by the first target group to instruct the terminal to dynamically determine the number of PUCCH retransmissions.

[0335] It should be noted that the first target group is the PDCCH candidate set, or the first target group is the PDCCH MO set.

[0336] Step 413: The base station configures a characterizing indication action for the second target group, where the indication action is: instructing the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner, wherein the second target group includes a PDCCH candidate set or a PDCCH MO set.

[0337] After obtaining the second target group, the base station needs to configure the corresponding indication action so that the terminal can perform the corresponding action after receiving the status information. During implementation, the base station configures the indication action represented by the second target group to instruct the terminal to determine the number of PUCCH retransmissions in a semi-static manner.

[0338] It should be noted that the second target group is the PDCCH candidate set, or the second target group is the PDCCH MO set.

[0339] Step 414: The base station generates first target information based on the first target group, the second target group and the instruction action.

[0340] After configuring the first target group and indication action, the base station generates first target information based on the above first target group and indication action, and after configuring the second target group and indication action, the base station generates second target information based on the above second target group and indication action, and sends it to the terminal to instruct the terminal to determine the number of PUCCH retransmissions in a dynamic or semi-static manner.

[0341] In addition, this situation also includes: if the base station does not configure the first target group and the second target group, instructing the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0342] During implementation, grouping information is configured using any of the following methods:

[0343] 1) Configured in the Search Space configuration information: In this case, the base station configures the grouping information of the PDCCH candidates in the Search Space configuration information, or the base station configures the grouping information of the PDCCH MO in the Search Space configuration information.

[0344] 2) Configured in the PUCCH resource-related configuration information indicated by the PRI field in the DCI. In this case, the base station configures the grouping information of the PDCCH candidates in the PUCCH resource-related configuration information indicated by the PRI field in the DCI, or the base station configures the grouping information of the PDCCH MO in the PUCCH resource-related configuration information indicated by the PRI field in the DCI.

[0345] 3) According to the predefined configuration of the protocol: In this case, the base station configures the grouping of PDCCH candidates or PDCCH MOs according to the predefined method in the protocol.

[0346] Considering that the indication in the second target information is any one of the control information carried in the MAC CE or the DCI, the following is a detailed description of each case, including:

[0347] The fifth case: the base station generates target information, see Figure 17 As shown, specifically including:

[0348] Step 511: The base station generates state information of PUCCH repetition enabling carried in the MAC CE, where the state information is an enabling state or a disabling state.

[0349] In order for the terminal to obtain the status information of PUCCH repetition enabling carried in the MAC CE, the base station needs to first generate the status information of PUCCH repetition enabling carried in the MAC CE. Specifically, the above status information is an enabled state or a disabled state. The enabled state and disabled state here can be flexibly distinguished by different values.

[0350] Step 512: The base station generates an indication action for the status information representation, wherein the indication action for the enabled status representation is: instructing the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner, and the indication action for the disabled status representation is: instructing the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0351] After generating the status information, the base station needs to generate a corresponding instruction action so that the terminal can perform the corresponding action after receiving the status information. During implementation, the base station generates the instruction action corresponding to the enabled state to instruct the terminal to dynamically determine the number of PUCCH retransmissions; and generates the instruction action corresponding to the disabled state to instruct the terminal to semi-statically determine the number of PUCCH retransmissions.

[0352] Of course, the base station can also generate the indication action corresponding to the enabled state to indicate that the terminal uses a semi-static method to determine the number of PUCCH repeated transmissions; generate the indication action corresponding to the enabled state to indicate that the terminal uses a dynamic method to determine the number of PUCCH repeated transmissions, thereby realizing flexible generation of indication actions.

[0353] During the implementation process, the base station generates an indication action corresponding to the enabled state to indicate that the terminal uses a dynamic method to determine the number of PUCCH retransmissions; and generates an indication action corresponding to the disabled state to indicate that the terminal uses a semi-static method to determine the number of PUCCH retransmissions.

[0354] Step 513: The base station generates second target information based on the state information and the instruction action.

[0355] After generating the status information and instruction action of PUCCH repetition enabling carried in the MAC CE, the base station generates first target information based on the above status information and instruction action, and sends it to the terminal to instruct the terminal to determine the number of PUCCH repetition transmissions in a dynamic or semi-static manner.

[0356] It should be noted here that the above-mentioned MAC CE takes effect at the time 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.

[0357] In the above steps, it is important to emphasize that the timing for obtaining the above-mentioned PUCCH repetition enabling status information is when the MAC CE is valid. Otherwise, the obtained PUCCH repetition enabling status information is invalid. If the MAC CE received by the terminal is not valid, the base station sets a default configuration to instruct the terminal to determine the number of repetitions dynamically or semi-statically.

[0358] Case 6: The base station generates target information, see Figure 18 As shown, specifically including:

[0359] Step 611: The base station presets a first state value or a second state value for the PUCCH repetition enabling indication field.

[0360] During implementation, the base station pre-generates a state value of the PUCCH repetition enabling indication field in the DCI, specifically including a first state value or a second state value. Typically, the base station generates the first state value or the second state value in control information.

[0361] Step 612: The base station generates an indication action representing the first state value, the indication action being: instructing the terminal to determine the number of PUCCH retransmissions in a dynamic manner; the base station generates an indication action representing the second state value, the indication action being: instructing the terminal to determine the number of PUCCH retransmissions in a semi-static manner.

[0362] After presetting the first state value or the second state value, the base station needs to generate a corresponding instruction action so that the terminal can perform the corresponding action after receiving the state information. During implementation, the base station generates the instruction action corresponding to the first state value as instructing the terminal to dynamically determine the number of PUCCH retransmissions; and generates the instruction action corresponding to the second state value as instructing the terminal to semi-statically determine the number of PUCCH retransmissions.

[0363] Of course, the base station can also generate the indication action corresponding to the first state value to indicate that the terminal uses a semi-static method to determine the number of PUCCH repeated transmissions; and generate the indication action corresponding to the second state value to indicate that the terminal uses a dynamic method to determine the number of PUCCH repeated transmissions, thereby achieving the purpose of flexibly generating state values.

[0364] Step 613: The base station generates second target information based on the preset state value and indication action of the PUCCH repetition enabling indication field.

[0365] After generating the above-mentioned first state value or second state value, the base station generates second target information based on the above-mentioned first state value, second state value and corresponding indication action, and sends it to the terminal to instruct the terminal to determine the number of PUCCH retransmissions in a dynamic or semi-static manner.

[0366] In addition, this situation also includes: if the base station does not generate a PUCCH repetition enabling indication field, in this mode, the terminal can be instructed by high-layer signaling to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0367] Step 202: The base station sends target information to the terminal, so that the terminal determines the number of PUCCH repetition transmissions in a dynamic or semi-static manner based on the target information.

[0368] During implementation, after the base station generates the first target information and the second target information (i.e., the target information), the base station sends the target information to the terminal, so that the terminal can dynamically or semi-statically determine the number of PUCCH repetition transmissions based on the target information. That is, the terminal dynamically or semi-statically determines the number of PUCCH repetition transmissions based on the first target information, or the terminal dynamically or semi-statically determines the number of PUCCH repetition transmissions based on the second target information.

[0369] The above embodiment is further described in detail below using several specific application scenarios.

[0370] Application scenario 1:

[0371] The base station configures three search spaces {#1, #2, #3} for the terminal. Among them, the PUCCH repetition enabling configured in search space #1 is in the enable state; the PUCCH repetition enabling configured in search space #2 is in the disable state; and no PUCCH repetition enabling related information is configured in search space #3.

[0372] At the same time, the base station configures an indication action for the status information that the PUCCH repetition enabling is enabled, that is, instructs the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner. Similarly, the base station configures an indication action for the status information that the PUCCH repetition enabling is disabled, that is, instructs the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0373] Since the terminal uses different methods to determine the number of repeated transmissions under different PUCCH repetition enabling status information, the base station needs to pre-configure the terminal with PUCCH resource sets corresponding to different search spaces, as shown in Table 1.

[0374] If the terminal receives a DCI in search space #1 scheduling a Physical Downlink Shared Channel (PDSCH), the PRI field in the DCI indicates not only the PUCCH resources but also the number of PUCCH repetitions. For example, the PRI field can determine the PUCCH resources and their corresponding repetitions based on the third or fourth column of Table 1. In this case, the PRI field can indicate two or four different PUCCH resources and their corresponding repetitions.

[0375] If a terminal receives a DCI in search space #2 scheduling a PDSCH, the PRI field in the DCI is used only to indicate PUCCH resources, as defined in Rel-15 / 16. In this case, the number of PUCCH repetitions is determined by nrofslot configured in the higher-layer parameter PUCCH-Config. For example, the PRI field determines the PUCCH resources according to the second column of Table 1. In this case, the PRI field can indicate eight different PUCCH resources, and the number of repetitions for each PUCCH is determined semi-statically.

[0376] If a terminal receives a PDSCH scheduled by a DCI in search space #3, the PRI field in the DCI is used by default only to indicate PUCCH resources. The number of PUCCH retransmissions is determined by the nrofslot configured in the PUCCH-Config. For example, the PRI field determines the PUCCH resources according to the second column of Table 1.

[0377] In addition, if the PUCCH repetition enabling information configured in the search spaces where the two DCI transmissions scheduling PDSCH are located is different, the HARQ-ACK feedback corresponding to the PDSCH needs to be transmitted in different time slots / sub-time slots, thereby avoiding the situation where the final determined PUCCH resources and the number of PUCCH repetition transmissions are different due to the different PUCCH resource sets corresponding to the two search spaces.

[0378] Application Scenario 2:

[0379] The base station configures three search spaces {#1, #2, #3} for the terminal. Among them, the PUCCH repetition enabling configured in search space #1 is in the enabled state; the PUCCH repetition enabling configured in search space #2 is in the disabled state; and no PUCCH repetition enabling related information is configured in search space #3.

[0380] At the same time, the base station configures an indication action for the status information that the PUCCH repetition enabling is enabled, that is, instructs the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner. Similarly, the base station configures an indication action for the status information that the PUCCH repetition enabling is disabled, that is, instructs the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0381] In addition, when configuring PUCCH resources, the base station configures an additional Search Space ID set in the PUCCH-Config, namely, search space ID list {search space #1, search space #2}. The base station pre-configures PUCCH resource sets corresponding to different search spaces for the terminal, as shown in Table 1.

[0382] If a terminal receives a DCI scheduling PDSCH in search space #1 and search space #2, the PRI field in the DCI must indicate not only the PUCCH resources but also the number of PUCCH repetitions. For example, the PRI field can determine the PUCCH resources and their corresponding repetitions based on the third or fourth column of Table 1. In this case, the PRI field can indicate two or four different PUCCH resources and their corresponding repetitions.

[0383] If a terminal receives a DCI in search space #3 scheduling a PDSCH, the PRI field in the DCI is used only to indicate PUCCH resources, as defined in Rel-15 / 16. In this case, the number of PUCCH repetitions is determined by nrofslot configured in the higher-layer parameter PUCCH-Config. For example, the PRI field determines the PUCCH resources according to the second column of Table 1. In this case, the PRI field can indicate eight different PUCCH resources, and the number of repetitions for each PUCCH is determined semi-statically.

[0384] Additionally, if the search spaces where the two DCI transmissions scheduling PDSCHs are located are configured with different PUCCH resource sets, the HARQ-ACK feedback corresponding to the PDSCHs needs to be transmitted in different time slots / sub-time slots, thereby avoiding the situation where the final determined PUCCH resources and the number of PUCCH repetition transmissions are different due to the different PUCCH resource sets corresponding to the two search spaces.

[0385] Application scenario 3:

[0386] The base station is configured with three BWPs {#1, #2, #3}, where PUCCH repetition enabling configured in BWP#1 is in the enable state; PUCCH repetition enabling configured in BWP#2 is in the disable state; and no PUCCH repetition enabling related information is configured in BWP#3.

[0387] At the same time, the base station configures an indication action for the status information of PUCCH repetition enabling configured in the above BWP as enable, that is, instructing the terminal to determine the number of PUCCH repetition transmissions in a dynamic manner. Similarly, the base station configures an indication action for the status information of PUCCH repetition enabling configured in the above BWP as disable, that is, instructing the terminal to determine the number of PUCCH repetition transmissions in a semi-static manner.

[0388] Since the terminal indicates the number of repeated transmissions in different ways under different PUCCH repetition enabling status information, the base station needs to pre-configure PUCCH resource sets corresponding to different BWPs for the terminal, as shown in Table 1.

[0389] If the terminal receives a DCI-scheduled PDSCH sent on BWP#1, the PRI field in the DCI indicates not only the PUCCH resources but also the number of PUCCH repetitions. For example, the PRI field can determine the PUCCH resources and their corresponding repetitions based on the third or fourth column of Table 1. In this case, the PRI field can indicate two or four different PUCCH resources and their corresponding repetitions.

[0390] If the terminal receives a DCI-scheduled PDSCH sent on BWP#2, the PRI field in the DCI is used only to indicate PUCCH resources, as defined in Rel-15 / 16. In this case, the number of PUCCH repetitions is determined by the nrofslot configured in PUCCH-Config. For example, the PRI field determines the PUCCH resources according to the second column of Table 1. In this case, the PRI field can indicate eight different PUCCH resources, and the number of repetitions for each PUCCH is determined semi-statically.

[0391] If the terminal receives a DCI-scheduled PDSCH sent on BWP#3, the PRI field in the DCI is used by default only to indicate PUCCH resources. The number of PUCCH retransmissions is determined by the nrofslot configured in PUCCH-Config. For example, the PRI field determines the PUCCH resources according to the second column of Table 1.

[0392] Similarly, since the terminal supports uplink and downlink operation in different BWPs, the terminal behavior can also be determined based on the BWP index of the PUCCH channel transmission indicated by the DCI. If the PUCCH channel is transmitted on BWP#1, the PRI field in the DCI also needs to indicate the number of PUCCH retransmissions in addition to indicating the PUCCH resource.

[0393] For example, the PRI domain can determine the PUCCH resources and their corresponding number of repeated transmissions according to the third or fourth column of Table 1. At this time, the PRI domain can indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions. If the PUCCH channel is transmitted on BWP#2, then according to the definition in Rel-15 / 16, the PRI domain in the DCI is only used to indicate the PUCCH resources, and the number of repeated transmissions of the PUCCH is determined by the nrofslot configured in the PUCCH-Config. For example, the PRI domain determines the PUCCH resources according to the second column of Table 1. At this time, the PRI domain can indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is determined by the semi-static configuration of the higher-layer signaling.

[0394] If the PUCCH channel is transmitted on BWP#3, the PRI field in the DCI is used by default only to indicate the PUCCH resource. The number of repeated transmissions of the PUCCH is determined by the nrofslot configured in the PUCCH-Config. In this case, the PRI field determines the PUCCH resource according to the second column of Table 1.

[0395] Application Scenario 4:

[0396] Assuming that there are a total of 8 PDCCH candidates in a search space, including PDCCH candidate indices #0 to #3 of aggregation level 2, PDCCH candidate indices #0 and #1 of aggregation level 4, and PDCCH candidate indices #0 and #1 of aggregation level 8, the base station can group the PDCCH candidates.

[0397] To ensure DCI reliability, each group of PDCCH candidates should include all aggregation levels as much as possible. For example, the PDCCH candidates with indices #0 and #1 for aggregation level 2, index #0 for aggregation level 4, and index #1 for aggregation level 8 are the first target group, and the PDCCH candidates with indices #2 and #3 for aggregation level 2, index #2 for aggregation level 4, and index #2 for aggregation level 8 are the second target group. The base station can configure the above group list in the search space or in the PUCCH resources. The base station needs to pre-configure the PUCCH resource sets corresponding to different PDCCH candidate groups for the terminal, as shown in Table 1.

[0398] If the terminal receives a DCI-scheduled PDSCH sent on a PDCCH candidate in the first target group PDCCH candidate, the PRI field in the DCI needs to indicate the number of PUCCH repetitions in addition to the PUCCH resource. For example, the PRI field can determine the PUCCH resource and its corresponding number of repetitions according to the third or fourth column of Table 1. In this case, the PRI field can indicate two or four different PUCCH resources and their corresponding number of repetitions.

[0399] If the terminal receives a DCI-scheduled PDSCH sent on a PDCCH candidate in the second target group, then according to the definition in Rel-15 / 16, the PRI field in the DCI is used only to indicate the PUCCH resource, and the number of PUCCH retransmissions is determined by the nrofslot configured in the PUCCH-Config. For example, the PRI field determines the PUCCH resource according to the second column of Table 1. In this case, the PRI field can indicate eight different PUCCH resources, and the number of retransmissions for each PUCCH is determined by the semi-static configuration configured by higher-layer signaling.

[0400] In addition, if the PDCCH candidate groups for the two DCI transmissions of scheduled PDSCH are different, the HARQ-ACK feedback corresponding to the above PDSCH needs to be transmitted in different time slots / sub-time slots. This is to avoid the different PUCCH and PUCCH repeated transmission times due to the different PUCCH resource sets corresponding to the two groups. During the implementation process, the PDCCH candidate position is determined by the CCE index indication, thereby determining the PUCCH set corresponding to the group to which the PDCCH candidate belongs. If the resource set for PUCCH format 0 / 1 configured by the base station for the terminal contains more than 8 entries, the prior art also needs to combine the CCE index to determine the final PUCCH resource. At this time, the CCE index may not be able to meet 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 have more than 8 entries.

[0401] Application Scenario 5:

[0402] Since the terminal indicates the number of repeated transmissions in different ways under different PUCCH repetition enabling configurations, the base station needs to pre-configure PUCCH resource sets corresponding to different PUCCH repetition enabling configuration information for the terminal, as shown in Table 1.

[0403] After the terminal receives the MAC CE sent by the base station through the PDSCH, it obtains the PUCCH repetition enabling related configuration information from it and feeds back the HARQ-ACK to the base station. If the PUCCH repetition enabling is in the enable state, after the MAC CE takes effect, the PRI field in the DCI received by the terminal needs to indicate the number of repeated transmissions of the PUCCH while indicating the PUCCH resources. For example, the PRI field can determine the PUCCH resources and their corresponding number of repeated transmissions according to the third or fourth column of Table 1. At this time, the PRI field can indicate 2 or 4 different PUCCH resources and their corresponding number of repeated transmissions.

[0404] If PUCCH repetition enabling is disabled, then 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 to indicate the PUCCH resource. The number of PUCCH retransmissions is determined by the nrofslot configured in the high-level parameter PUCCH-Config. For example, the PRI field determines the PUCCH resource according to the second column of Table 1. In this case, the PRI field can indicate 8 different PUCCH resources, and the number of repetitions for each PUCCH is semi-statically configured. During implementation, the current MAC CE takes effect after the base station receives the ACK feedback from the terminal.

[0405] When MAC CE is not effective, the default PUCCH repetition enabling related configuration information is either enable or disable.

[0406] Application Scenario 6:

[0407] Since the terminal indicates the number of repeated transmissions in different ways under different PUCCH repetition enabling configurations, the base station needs to pre-configure PUCCH resource sets corresponding to different PUCCH repetition enabling configuration information for the terminal, as shown in Table 1.

[0408] The terminal receives the non-fullback DCI that schedules PDSCH. After parsing the DCI, if there is no PUCCH repetition enabling field in the DCI, the PRI field in the DCI is used by default only to indicate the PUCCH resources, and the number of repeated transmissions of the PUCCH is determined by the nrofslot configured in the high-level parameter PUCCH-Config. For example, the PRI field determines the PUCCH resources according to the second column configuration of Table 1. At this time, the PRI field can indicate 8 different PUCCH resources, and the number of repeated transmissions of each PUCCH is determined by the semi-static configuration of the high-level signaling. If the PUCCH repetition enabling field is configured in the DCI, when the field value is 0, the PRI field in the DCI needs to indicate the number of repeated transmissions of the PUCCH while indicating the PUCCH resources. For example, the PRI field can determine the PUCCH resources and their corresponding number of repeated transmissions according to the third or fourth column configuration of Table 1. At this time, the PRI field can 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 field in the DCI is only used to indicate PUCCH resources, and the number of repeated transmissions of PUCCH is determined by nrofslot configured in the higher-layer parameter PUCCH-Config.
