Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a feedback information transmission method and device, user equipment, base station, and computer-readable storage medium. Background Art

[0002] In the fifth generation mobile communication technology (5th Generation, 5G) New Radio (NR), ultra reliable and low latency communication (URLLC) service is a very important service type, which will be widely used in 5G scenarios such as factory automation, remote control, augmented reality (AR) or virtual reality (VR). URLLC services usually require very high reliability and very low latency. Another service type is the enhanced mobile broadband (eMBB) service type, which usually requires a higher rate, but does not require very low latency and very low error rate. Therefore, in comparison, the URLLC service type has a higher priority.

[0003] However, when the same terminal has URLLC services and eMBB services concurrently, and the URLLC services and eMBB services are mixed and scheduled on the same carrier, or when the user equipment (UE) uses the same transceiver link to process the data of the URLLC services and eMBB services, there may be a transmission conflict between the transmission of the URLLC data and the eMBB's Hybrid Automatic Repeat request acknowledgement (HARQ-ACK). At this time, it is very likely that the URLLC data will be transmitted first to ensure the high reliability and low latency characteristics of the URLLC service. Therefore, the eMBB's HARQ-ACK will be punctured or discarded.

[0004] However, for eMBB transmission, since the latency requirement is not high, it is possible to combine the HARQ-ACK of multiple eMBB physical downlink shared channels (PDSCH) into a HARQ-ACK codebook for transmission. If this HARQ-ACK codebook is punctured or discarded by URLLC transmission, a large amount of eMBB data will be retransmitted. Summary of the invention

[0117] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0118] Figure 1 is a flowchart of a feedback information transmission method shown in an exemplary embodiment of the present application. This embodiment is described from the UE side. Figure 1 As shown, the feedback information transmission method includes:

[0119] In step S101, after a set time period when feedback information of first service data conflicts with transmission of second service data, first downlink control information (DCI) sent by a base station is received, wherein the priority of the first service is lower than that of the second service.

[0120] The first service may include but is not limited to the eMBB service, and the second service may include but is not limited to the URLLC service. The duration is set to be greater than or equal to the duration during which the UE and the base station can both learn that the feedback information of the first service data conflicts with the transmission of the second service data.

[0121] The transmission conflict between the feedback information of the first service data and the second service data may include but is not limited to the following situations:

[0122] Case 1) There is a transmission conflict between feedback information of the first service data and second service data transmitted using a semi-statically configured physical uplink shared channel (PUSCH) resource.

[0123] In this case, when the feedback information of the first service data conflicts with the transmission of the second service data, the UE can know that the feedback information of the current first service data conflicts. However, the base station needs to blindly detect whether there is a semi-statically configured PUSCH resource transmission before determining that the feedback information of the current first service data conflicts. Therefore, the base station learns that the feedback information of the first service data conflicts with the transmission of the second service data after a period of time T1, where T1 is the duration of the base station demodulating the PUSCH resource, that is, the set duration is greater than or equal to the first duration of the base station demodulating the PUSCH resource.

[0124] Case 2) There is a transmission conflict between the feedback information of the first service data and the second service data transmitted using the semi-statically configured scheduling request (SR) resources.

[0125] This situation is similar to situation 1). The UE knows that a transmission conflict has occurred when it occurs, but the base station needs to know it after the T2 time period has passed, where T2 is the duration of the base station demodulating SR. That is, in this case, the setting duration is greater than or equal to the second duration of the base station demodulating SR resources.

[0126] Case 3) There is a transmission conflict between the feedback information of the first service data and the feedback information of the second service data.

[0127] If the feedback information of the second service data corresponds to the HARQ-ACK of the dynamically scheduled physical downlink shared channel (PDSCH), the base station will know that a conflict will occur when sending the second service DCI. The UE will know that a conflict will occur when it demodulates the second service DCI. At this time, the UE and the base station know that the conflict will occur earlier than the actual time when the conflict occurs, but the UE knows that the conflict will occur slightly later than the base station. It can be seen that in this case, the duration is set to the third duration, and the third duration is greater than or equal to 0.

[0128] If the feedback information of the second service data corresponds to the HARQ-ACK of the semi-statically configured PDSCH, the base station will know that a conflict will occur when sending the second service PDSCH. However, the UE will not know that a conflict will occur until it has demodulated the second service PDSCH. At this time, the UE and the base station know that the conflict occurred earlier than the actual time when the conflict occurred, but the UE knows that the conflict occurred later than the base station. It can be seen that in this case, the duration is set to the third duration, and the third duration is greater than or equal to 0.

[0129] Case 4) There is a transmission conflict between the feedback information of the first service data and the second service data transmitted using the dynamically scheduled PUSCH resources.

[0130] This situation is similar to situation 3). The base station knows that a conflict is about to occur when issuing the second service uplink (UL) scheduling (grant), and the UE knows that a conflict is about to occur after blindly detecting the UL grant. That is, the UE and the base station know that the conflict occurs earlier than the actual time when the conflict occurs, but the UE knows that the conflict occurs slightly later than the base station. It can be seen that in this case, the fourth time length is set, and the fourth time length is greater than or equal to 0.

[0131] It can be seen that, in different transmission conflict situations, the base station and the UE can know that the conflict is about to occur or the conflict has occurred for different lengths of time.

[0132] In this embodiment, the set duration can be set according to different conflict situations, or a fixed value can be selected according to all possible conflict situations. The fixed value is the maximum value of the set duration in all situations, that is, the maximum value of the first duration, the second duration, the third duration and the fourth duration.

[0133] Optionally, the method may further include: agreeing on the above-mentioned set duration in a communication protocol, and may also include: receiving a high-layer signaling sent by a base station, and parsing the above-mentioned set duration from the high-layer signaling.

[0134] In step S102, transmission resources for feedback information for retransmitting first service data are obtained from the first DCI.

[0135] The DCI may include downlink (DL) grant information, and the downlink grant information is used to schedule the PDSCH and the corresponding PUCCH for downlink data transmission of the first service. In this case, obtaining the transmission resources for feedback information for retransmitting the first service data from the first DCI may include: obtaining the PUCCH resources for feedback information for retransmitting the first service data from the first downlink grant information.

[0136] The DCI may include uplink (UL) scheduling information, and the uplink scheduling information is used to schedule the PUSCH for uplink data transmission of the first service. In this case, obtaining the transmission resources for feedback information for retransmitting the first service data from the first DCI may include: obtaining the PUSCH resources for feedback information for retransmitting the first service data from the first uplink scheduling information.

[0137] In step S103, the feedback information of the first service data is retransmitted using the transmission resources.

[0138] After acquiring the transmission resource for retransmitting the feedback information of the first service data from the first DCI, the feedback information of the first service data is retransmitted using the transmission resource.

[0139] The above embodiment receives the first DCI sent by the base station after a set period of time when the feedback information of the first business data conflicts with the second business data in transmission, obtains the transmission resources for retransmitting the feedback information of the first business data from the first DCI, and uses the transmission resources to retransmit the feedback information of the first business data. This solves the problem of retransmitting the feedback information of the first business data after the feedback information of the first business data is punctured or discarded in a mixed transmission scenario of the first business data and the second business data, thereby avoiding unnecessary retransmission of the first business PDSCH by the base station.

[0140] Figure 2is a flowchart of another feedback information transmission method shown in an exemplary embodiment of the present application. Figure 2 As shown, the feedback information transmission method is applied to a base station, and the method includes:

[0141] In step S201, after a set period of time when feedback information of first service data conflicts with transmission of second service data, transmission resources for retransmitting feedback information of the first service data are indicated in the first DCI sent to the UE, wherein the priority of the first service is lower than that of the second service.

[0142] The first service may include but is not limited to the eMBB service, and the second service may include but is not limited to the URLLC service. The duration is set to be greater than or equal to the duration during which the UE and the base station can both learn that the feedback information of the first service data conflicts with the transmission of the second service data.

[0143] The transmission conflict between the feedback information of the first service data and the second service data may include but is not limited to the following situations:

[0144] Case 1) There is a transmission conflict between feedback information of the first service data and second service data transmitted using a semi-statically configured physical uplink shared channel (PUSCH) resource.

[0145] In this case, when the feedback information of the first service data conflicts with the transmission of the second service data, the UE can know that the feedback information of the current first service data conflicts. However, the base station needs to blindly detect whether there is a semi-statically configured PUSCH resource transmission before determining that the feedback information of the current first service data conflicts. Therefore, the base station learns that the feedback information of the first service data conflicts with the transmission of the second service data after a period of time T1, where T1 is the duration of the base station demodulating the PUSCH resource, that is, the set duration is greater than or equal to the first duration of the base station demodulating the PUSCH resource.

[0146] Case 2) There is a transmission conflict between the feedback information of the first service data and the second service data transmitted using the semi-statically configured scheduling request (SR) resources.

[0147] This situation is similar to situation 1). The UE knows that a transmission conflict has occurred when it occurs, but the base station needs to know it after the T2 time period has passed, where T2 is the duration of the base station demodulating SR. That is, in this case, the setting duration is greater than or equal to the second duration of the base station demodulating SR resources.

[0148] Case 3) There is a transmission conflict between the feedback information of the first service data and the feedback information of the second service data.

[0149] If the feedback information of the second service data corresponds to the HARQ-ACK of the dynamically scheduled physical downlink shared channel (PDSCH), the base station will know that a conflict will occur when sending the second service DCI. The UE will know that a conflict will occur when it demodulates the second service DCI. At this time, the UE and the base station know that the conflict will occur earlier than the actual time when the conflict occurs, but the UE knows that the conflict will occur slightly later than the base station. It can be seen that in this case, the duration is set to the third duration, and the third duration is greater than or equal to 0.

[0150] If the feedback information of the second service data corresponds to the HARQ-ACK of the semi-statically configured PDSCH, the base station will know that a conflict will occur when sending the second service PDSCH. However, the UE will not know that a conflict will occur until it has demodulated the second service PDSCH. At this time, the UE and the base station know that the conflict occurred earlier than the actual time when the conflict occurred, but the UE knows that the conflict occurred later than the base station. It can be seen that in this case, the duration is set to the third duration, and the third duration is greater than or equal to 0.

[0151] Case 4) There is a transmission conflict between the feedback information of the first service data and the second service data transmitted using the dynamically scheduled PUSCH resources.

[0152] This situation is similar to situation 3). The base station knows that a conflict is about to occur when issuing the second service uplink (UL) scheduling (grant), and the UE knows that a conflict is about to occur after blindly detecting the UL grant. That is, the UE and the base station know that the conflict occurs earlier than the actual time when the conflict occurs, but the UE knows that the conflict occurs slightly later than the base station. It can be seen that in this case, the fourth time length is set, and the fourth time length is greater than or equal to 0.

[0153] It can be seen that, in different transmission conflict situations, the base station and the UE can know that the conflict is about to occur or the conflict has occurred for different lengths of time.

[0154] In this embodiment, the set duration can be set according to different conflict situations, or a fixed value can be selected according to all possible conflict situations. The fixed value is the maximum value of the set duration in all situations, that is, the maximum value of the first duration, the second duration, the third duration and the fourth duration.

[0155] Optionally, the method may further include: agreeing on the above-mentioned set duration in a communication protocol, and may also include: configuring the set duration for the UE, and sending a high-layer signaling to the UE, wherein the high-layer signaling carries the set duration.

[0156] In step S202, feedback information of first service data retransmitted by the UE using transmission resources is received.

[0157] In this embodiment, after a set duration of transmission conflict between the feedback information of the first service data and the second service data, the base station indicates the transmission resources for retransmitting the feedback information of the first service data in the first DCI sent to the UE. After receiving the first DCI, the UE obtains the transmission resources for retransmitting the feedback information of the first service data, and uses the transmission resources to retransmit the feedback information of the first service data.

[0158] Wherein, the DCI may include downlink (DL) scheduling (grant) information, and the downlink scheduling information is used to schedule the PDSCH and the corresponding PUCCH for downlink data transmission of the first service. In this case, the method of indicating the transmission resources for feedback information for retransmitting the first service data in the first downlink control information DCI sent to the UE may include: indicating the PUCCH resources for feedback information for retransmitting the first service data in the first downlink scheduling information sent to the UE.

[0159] The DCI may include uplink (UL) scheduling information, and the uplink scheduling information is used to schedule the PUSCH for uplink data transmission of the first service. In this case, the method of indicating the transmission resource for feedback information for retransmitting the first service data in the first downlink control information DCI sent to the UE may include: indicating the PUSCH resource for feedback information for retransmitting the first service data in the first uplink scheduling information sent to the UE.

[0160] In the above embodiment, after a set period of time has passed since the feedback information of the first service data conflicts with the second service data, the base station indicates the transmission resources for retransmitting the feedback information of the first service data in the first DCI sent to the UE, and receives the feedback information of the first service data retransmitted by the UE using the transmission resources, so that the base station can obtain the transmission status of the first service data and avoid unnecessary retransmission of the first service PDSCH.

[0161] Figure 3 is a signaling flow chart of a feedback information transmission method shown in an exemplary embodiment of the present application. This embodiment is described from the perspective of interaction between a base station and a UE. Figure 3 As shown, the method includes:

[0162] In step S301, after a set duration of transmission conflict between feedback information of the first service data and second service data, the base station indicates transmission resources for retransmitting feedback information of the first service data in the first DCI sent to the UE, wherein the priority of the first service is lower than that of the second service.

[0163] In this embodiment, the feedback information of the first service data is HARQ-ACK of eMBB data, and the second service data is URLLC data.

[0164] The DCI may be downlink scheduling information or uplink scheduling information. If there is no PDSCH to be transmitted at this time, the uplink scheduling information may be preferably used.

[0165] In step S302, the UE receives the first DCI sent by the base station after a set time duration when feedback information of the first service data conflicts with the second service data.

[0166] In step S303, the UE obtains transmission resources for retransmitting feedback information of the first service data from the first DCI.

[0167] In step S304, the base station receives feedback information of the first service data retransmitted by the UE using the transmission resources.

[0168] In the above-mentioned embodiment, through the interaction between the base station and the UE, the base station indicates the transmission resources for retransmitting the feedback information of the first service data in the first DCI sent to the UE after a set period of time when the feedback information of the first service data conflicts with the second service data, and receives the feedback information of the first service data retransmitted by the UE using the transmission resources, so that the base station can obtain the transmission status of the first service data and avoid unnecessary retransmission of the first service PDSCH.

[0169] Figure 4 is a block diagram of a feedback information transmission device according to an exemplary embodiment, the device is located in a UE, such as Figure 4 As shown, the device comprises:

[0170] The receiving module 41 is configured to receive first downlink control information DCI sent by the base station after a set time period when feedback information of the first service data conflicts with transmission of the second service data, wherein the priority of the first service is lower than that of the second service.

[0171] The first service may include but is not limited to the eMBB service, and the second service may include but is not limited to the URLLC service. The duration is set to be greater than or equal to the duration during which the UE and the base station can both learn that the feedback information of the first service data conflicts with the transmission of the second service data.

[0172] The transmission conflict between the feedback information of the first service data and the second service data may include but is not limited to the following situations:

[0173] Case 1) There is a transmission conflict between feedback information of the first service data and second service data transmitted using a semi-statically configured physical uplink shared channel (PUSCH) resource.

[0174] In this case, when the feedback information of the first service data conflicts with the transmission of the second service data, the UE can know that the feedback information of the current first service data conflicts. However, the base station needs to blindly detect whether there is a semi-statically configured PUSCH resource transmission before determining that the feedback information of the current first service data conflicts. Therefore, the base station learns that the feedback information of the first service data conflicts with the transmission of the second service data after a period of time T1, where T1 is the duration of the base station demodulating the PUSCH resource, that is, the set duration is greater than or equal to the first duration of the base station demodulating the PUSCH resource.

[0175] Case 2) There is a transmission conflict between the feedback information of the first service data and the second service data transmitted using the semi-statically configured scheduling request (SR) resources.

[0176] This situation is similar to situation 1). The UE knows that a transmission conflict has occurred when it occurs, but the base station needs to know it after the T2 time period has passed, where T2 is the duration of the base station demodulating SR. That is, in this case, the setting duration is greater than or equal to the second duration of the base station demodulating SR resources.

[0177] Case 3) There is a transmission conflict between the feedback information of the first service data and the feedback information of the second service data.

[0178] If the feedback information of the second service data corresponds to the HARQ-ACK of the dynamically scheduled physical downlink shared channel (PDSCH), the base station will know that a conflict will occur when sending the second service DCI. The UE will know that a conflict will occur when it demodulates the second service DCI. At this time, the UE and the base station know that the conflict will occur earlier than the actual time when the conflict occurs, but the UE knows that the conflict will occur slightly later than the base station. It can be seen that in this case, the duration is set to the third duration, and the third duration is greater than or equal to 0.

[0179] If the feedback information of the second service data corresponds to the HARQ-ACK of the semi-statically configured PDSCH, the base station will know that a conflict will occur when sending the second service PDSCH. However, the UE will not know that a conflict will occur until it has demodulated the second service PDSCH. At this time, the UE and the base station know that the conflict occurred earlier than the actual time when the conflict occurred, but the UE knows that the conflict occurred later than the base station. It can be seen that in this case, the duration is set to the third duration, and the third duration is greater than or equal to 0.

[0180] Case 4) There is a transmission conflict between the feedback information of the first service data and the second service data transmitted using the dynamically scheduled PUSCH resources.

[0181] This situation is similar to situation 3). The base station knows that a conflict is about to occur when issuing the second service uplink (UL) scheduling (grant), and the UE knows that a conflict is about to occur after blindly detecting the UL grant. That is, the UE and the base station know that the conflict occurs earlier than the actual time when the conflict occurs, but the UE knows that the conflict occurs slightly later than the base station. It can be seen that in this case, the fourth time length is set, and the fourth time length is greater than or equal to 0.

[0182] It can be seen that, in different transmission conflict situations, the base station and the UE can know that the conflict is about to occur or the conflict has occurred for different lengths of time.

[0183] In this embodiment, the set duration can be set according to different conflict situations, or a fixed value can be selected according to all possible conflict situations. The fixed value is the maximum value of the set duration in all situations, that is, the maximum value of the first duration, the second duration, the third duration and the fourth duration.

[0184] The acquisition module 42 is configured to acquire, from the first DCI received by the receiving module 41 , transmission resources for feedback information for retransmitting the first service data.

[0185] The DCI may include downlink (DL) grant information, and the downlink grant information is used to schedule the PDSCH and the corresponding PUCCH for downlink data transmission of the first service. In this case, obtaining the transmission resources for feedback information for retransmitting the first service data from the first DCI may include: obtaining the PUCCH resources for feedback information for retransmitting the first service data from the first downlink grant information.

[0186] The DCI may include uplink (UL) scheduling information, and the uplink scheduling information is used to schedule the PUSCH for uplink data transmission of the first service. In this case, obtaining the transmission resources for feedback information for retransmitting the first service data from the first DCI may include: obtaining the PUSCH resources for feedback information for retransmitting the first service data from the first uplink scheduling information.

[0187] The retransmission module 43 is configured to retransmit the feedback information of the first service data using the transmission resources acquired by the acquisition module 42 .

[0188] After acquiring the transmission resource for retransmitting the feedback information of the first service data from the first DCI, the feedback information of the first service data is retransmitted using the transmission resource.

[0189] The above embodiment receives the first DCI sent by the base station after a set period of time when the feedback information of the first business data conflicts with the second business data in transmission, obtains the transmission resources for retransmitting the feedback information of the first business data from the first DCI, and uses the transmission resources to retransmit the feedback information of the first business data. This solves the problem of retransmitting the feedback information of the first business data after the feedback information of the first business data is punctured or discarded in a mixed transmission scenario of the first business data and the second business data, thereby avoiding unnecessary retransmission of the first business PDSCH by the base station.

[0190] Figure 5 is a block diagram of another feedback information transmission device according to an exemplary embodiment. Figure 5 As shown in the above Figure 4 On the basis of the illustrated embodiment, the device may further include: a receiving and parsing module 44 .

[0191] The receiving and parsing module 44 is configured to receive a high-layer signaling sent by a base station, and parse the high-layer signaling to obtain a set duration.

[0192] In the above embodiment, the set duration is parsed from the received high-level signaling, and the implementation is simple.

Figure 6 As shown in the above Figure 4 On the basis of the illustrated embodiment, the acquisition module 42 may include: a first acquisition submodule 421 or a second acquisition submodule 422 .

[0194] The first acquisition submodule 421 is configured to acquire, from the first downlink scheduling information, a PUCCH resource for retransmitting feedback information of the first service data.

[0195] The second acquisition submodule 422 is configured to acquire, from the first uplink scheduling information, a PUSCH resource for retransmitting feedback information of the first service data.

[0196] In the above embodiment, the PUCCH resource for retransmitting the feedback information of the first service data is obtained from the first downlink scheduling information, or the PUSCH resource for retransmitting the feedback information of the first service data is obtained from the first uplink scheduling information, so the implementation method is flexible and diverse.

[0198] The indication module 71 is used to indicate the transmission resources for retransmitting the feedback information of the first service data in the first downlink control information DCI sent to the user equipment UE after a set period of time when the feedback information of the first service data conflicts with the transmission of the second service data, wherein the priority of the first service is lower than the priority of the second service.

[0199] The first service may include but is not limited to the eMBB service, and the second service may include but is not limited to the URLLC service. The duration is set to be greater than or equal to the duration during which the UE and the base station can both learn that the feedback information of the first service data conflicts with the transmission of the second service data.

[0200] The transmission conflict between the feedback information of the first service data and the second service data may include but is not limited to the following situations:

[0201] Case 1) There is a transmission conflict between feedback information of the first service data and second service data transmitted using a semi-statically configured physical uplink shared channel (PUSCH) resource.

[0202] In this case, when the feedback information of the first service data conflicts with the transmission of the second service data, the UE can know that the feedback information of the current first service data conflicts. However, the base station needs to blindly detect whether there is a semi-statically configured PUSCH resource transmission before determining that the feedback information of the current first service data conflicts. Therefore, the base station learns that the feedback information of the first service data conflicts with the transmission of the second service data after a period of time T1, where T1 is the duration of the base station demodulating the PUSCH resource, that is, the set duration is greater than or equal to the first duration of the base station demodulating the PUSCH resource.

[0203] Case 2) There is a transmission conflict between the feedback information of the first service data and the second service data transmitted using the semi-statically configured scheduling request (SR) resources.

[0204] This situation is similar to situation 1). The UE knows that a transmission conflict has occurred when it occurs, but the base station needs to know it after the T2 time period has passed, where T2 is the duration of the base station demodulating SR. That is, in this case, the setting duration is greater than or equal to the second duration of the base station demodulating SR resources.

[0205] Case 3) There is a transmission conflict between the feedback information of the first service data and the feedback information of the second service data.

[0206] If the feedback information of the second service data corresponds to the HARQ-ACK of the dynamically scheduled physical downlink shared channel (PDSCH), the base station will know that a conflict will occur when sending the second service DCI. The UE will know that a conflict will occur when it demodulates the second service DCI. At this time, the UE and the base station know that the conflict will occur earlier than the actual time when the conflict occurs, but the UE knows that the conflict will occur slightly later than the base station. It can be seen that in this case, the duration is set to the third duration, and the third duration is greater than or equal to 0.

[0207] If the feedback information of the second service data corresponds to the HARQ-ACK of the semi-statically configured PDSCH, the base station will know that a conflict will occur when sending the second service PDSCH. However, the UE will not know that a conflict will occur until it has demodulated the second service PDSCH. At this time, the UE and the base station know that the conflict occurred earlier than the actual time when the conflict occurred, but the UE knows that the conflict occurred later than the base station. It can be seen that in this case, the duration is set to the third duration, and the third duration is greater than or equal to 0.

[0208] Case 4) There is a transmission conflict between the feedback information of the first service data and the second service data transmitted using the dynamically scheduled PUSCH resources.

[0209] This situation is similar to situation 3). The base station knows that a conflict is about to occur when issuing the second service uplink (UL) scheduling (grant), and the UE knows that a conflict is about to occur after blindly detecting the UL grant. That is, the UE and the base station know that the conflict occurs earlier than the actual time when the conflict occurs, but the UE knows that the conflict occurs slightly later than the base station. It can be seen that in this case, the fourth time length is set, and the fourth time length is greater than or equal to 0.

[0210] It can be seen that, in different transmission conflict situations, the base station and the UE can know that the conflict is about to occur or the conflict has occurred for different lengths of time.

[0211] In this embodiment, the set duration can be set according to different conflict situations, or a fixed value can be selected according to all possible conflict situations. The fixed value is the maximum value of the set duration in all situations, that is, the maximum value of the first duration, the second duration, the third duration and the fourth duration.

[0212] The receiving module 72 is used to receive feedback information of the first service data retransmitted by the UE using the transmission resources indicated by the indication module.

[0213] In this embodiment, after a set duration of transmission conflict between the feedback information of the first service data and the second service data, the base station indicates the transmission resources for retransmitting the feedback information of the first service data in the first DCI sent to the UE. After receiving the first DCI, the UE obtains the transmission resources for retransmitting the feedback information of the first service data, and uses the transmission resources to retransmit the feedback information of the first service data.

[0214] Wherein, the DCI may include downlink (DL) scheduling (grant) information, and the downlink scheduling information is used to schedule the PDSCH and the corresponding PUCCH for downlink data transmission of the first service. In this case, the method of indicating the transmission resources for feedback information for retransmitting the first service data in the first downlink control information DCI sent to the UE may include: indicating the PUCCH resources for feedback information for retransmitting the first service data in the first downlink scheduling information sent to the UE.

[0215] The DCI may include uplink (UL) scheduling information, and the uplink scheduling information is used to schedule the PUSCH for uplink data transmission of the first service.
