Description

Feedback resource configuration method and terminal device

Technical Field

The present application relates to the field of communications, and in particular, to a method for configuring feedback resources and a terminal device.

Background

Currently, in the process of communicating between terminal devices on a Sidelink (SL), traffic data, such as Unicast (UC) data or Multicast (MC) data, is transmitted on a traffic channel, such as a physical sidelink shared channel (psch), feedback information corresponding to the traffic data, such as Acknowledgement (ACK) or Negative Acknowledgement (NACK) of a hybrid automatic repeat request (HARQ), Channel Quality Information (CQI), and the like, is transmitted on a feedback channel, such as a physical sidelink feedback channel (pscch). In order to improve the transmission efficiency of the feedback information, the feedback information corresponding to the traffic data of a plurality of slots (slots) in the same slot interval is generally transmitted in a single feedback slot. For example, assuming that the slot interval may be configured to be 4, and the offset of the feedback slot is 0, the feedback information corresponding to the traffic data transmitted on slots 0 to 3 is transmitted on slot 4.

However, for different services, the time slot intervals between the feedback time slots are usually the same value, and are preconfigured, and cannot be dynamically indicated through signaling, and cannot be applied to services with different delay requirements, and also cannot be applied to services with different feedback information quantities, and the flexibility is poor.

Disclosure of Invention

The embodiment of the application provides a method and a device for configuring feedback resources, which can improve the configuration efficiency and flexibility of the feedback resources, thereby improving the transmission efficiency of feedback information.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, a method for configuring feedback resources is provided. The method comprises the following steps: the first terminal device receives first configuration information from the network device. The first configuration information is used for indicating at least two feedback resource sets, and the at least two feedback resource sets comprise a first feedback resource set and a second feedback resource set; the first set of feedback resources is different from the second set of feedback resources. Then, the first terminal device selects the first feedback resource set or the second feedback resource set, and transmits feedback information on the selected feedback resource set.

According to the method for configuring feedback resources provided by the embodiment of the application, the first terminal device can select different feedback resource sets according to the data amount and/or feedback delay of the feedback information of different services from at least two feedback resource sets indicated by the first configuration information, such as the first feedback resource set or the second feedback resource set, so that when the feedback information of different services is sent at a time interval between the same preconfigured feedback resources, the problems that the feedback resources are insufficient or wasted, the transmission delay of the feedback information cannot meet the delay requirement and the like due to different data amounts of the feedback information of different services or different transmission delays required by the feedback information can be avoided, the configuration efficiency and flexibility of the feedback resources can be improved, and the transmission efficiency of the feedback information can be improved.

Illustratively, the first set of feedback resources may include one or more of the following items, different from the second set of feedback resources: the time domain resources contained in the first feedback resource set are different from the time domain resources contained in the second feedback resource set; the frequency domain resources contained in the first feedback resource set are different from the frequency domain resources contained in the second feedback resource set; the code domain resources contained in the first feedback resource set are different from the code domain resources contained in the second feedback resource set; the spatial domain resources contained in the first feedback resource set are different from the spatial domain resources contained in the second feedback resource set; the first set of feedback resources comprises orthogonal sequences that are different from the orthogonal sequences comprised by the second set of feedback resources.

In a possible design method, the time domain resources included in the first feedback resource set are different from the time domain resources included in the second feedback resource set, and the method may include: the time slot interval between any two adjacent feedback resources in the first feedback resource set is the same as the time slot interval between any two adjacent feedback resources in the second feedback resource set, and the time slot offset of the first feedback resource set is different from the time slot offset of the second feedback resource set, so as to ensure that no conflict exists between the time domain resources contained in the first feedback resource set and the time domain resources contained in the second feedback resource set.

In another possible design method, the time domain resources included in the first feedback resource set and the time domain resources included in the second feedback resource set are different, and the method may include: the time slot interval between any two adjacent feedback resources in the first feedback resource set is different from the time slot interval between any two adjacent feedback resources in the second feedback resource set.

It is easily understood that the different time slot intervals may cause the time domain resources contained in the first feedback resource set to collide with the time domain resources contained in the second feedback resource set. Therefore, optionally, the time domain resources included in the first feedback resource set are different from the time domain resources included in the second feedback resource set, and the method may further include: if the first feedback resource set and the second feedback resource set both include the first time domain resource, the first time domain resource is only used for sending the feedback information of the first service. The first service is a high-priority service and/or a low-transmission-delay service. That is, when the time domain resources included in the first feedback resource set and the second feedback resource set conflict, it may be preferentially ensured that the feedback information of the high priority service and/or the low transmission delay service is transmitted.

It should be understood that, for a low priority service and/or a high transmission delay service, the feedback information, such as the feedback information of the second service, may be processed by any one of the following processing manners, as appropriate:

optionally, the second feedback resource set further includes a second time domain resource. Correspondingly, the first time domain resource is a first time slot, the second time domain resource is a second time slot, and the second time slot is a next time slot of the first time slot. Or, the first time domain resource and the second time domain resource respectively comprise different symbols in the same time slot.

Or optionally, the feedback information of the second service that originally needs to be sent on the first time domain resource may not be sent any more, that is, the feedback information of the second service that originally needs to be sent on the first time domain resource is abandoned.

It should be noted that the feedback information of the second service related to the forgoing transmission scheme is only feedback information of the second service that originally needs to be transmitted on the first time domain resource, and the feedback information of the second service that is transmitted on other time domain resources, except the first time domain resource, in the second feedback resource set and that does not collide with the time domain resource in the first feedback resource set still needs to be transmitted.

Further, both the first feedback resource set and the second feedback resource set may be feedback resource sets in the same configuration period. Wherein one configuration period may include a plurality of consecutive time slots.

Optionally, the first set of feedback resources and the second set of feedback resources may be configured separately in the same configuration period. And/or, optionally, the first set of feedback resources is the same in two adjacent configuration periods, and the second set of feedback resources is the same in two adjacent configuration periods.

In a second aspect, a method for configuring feedback resources is provided. The method comprises the following steps: the second terminal device receives the first configuration information from the network device. The first configuration information is used for indicating at least two feedback resource sets, and the at least two feedback resource sets comprise a first feedback resource set and a second feedback resource set; the first set of feedback resources is different from the second set of feedback resources. Then, the second terminal device selects the first feedback resource set or the second feedback resource set, and receives feedback information on the selected feedback resource set.

It is easily understood that the different time slot intervals may cause the time domain resources contained in the first feedback resource set to collide with the time domain resources contained in the second feedback resource set. Therefore, optionally, the time domain resources included in the first feedback resource set are different from the time domain resources included in the second feedback resource set, and the method may further include: if the first feedback resource set and the second feedback resource set both include the first time domain resource, the first time domain resource is only used for receiving the feedback information of the first service. The first service is a high-priority service and/or a low-transmission-delay service.

Or, optionally, the feedback information of the second service that originally needs to be received on the first time domain resource may not be received any more, that is, the feedback information of the second service that originally needs to be received on the first time domain resource is abandoned.

It should be noted that the feedback information of the second service related to the forgoing reception scheme only refers to the feedback information of the second service that originally needs to be received on the first time domain resource, and the feedback information of the second service that is received on other time domain resources, except the first time domain resource, in the second feedback resource set and that does not conflict with the time domain resource in the first feedback resource set still needs to be received.

The technical effect of the method for configuring feedback resources according to the second aspect may refer to the technical effect of the method for configuring feedback resources according to the first aspect, and is not described herein again.

In a third aspect, a terminal device is provided. The device includes: a processing module and a transceiver module. The receiving and sending module is used for receiving first configuration information from the network device. The first configuration information is used for indicating at least two feedback resource sets, and the at least two feedback resource sets comprise a first feedback resource set and a second feedback resource set; the first set of feedback resources is different from the second set of feedback resources. And the processing module is used for selecting the first feedback resource set or the second feedback resource set. And the transceiver module is further used for transmitting the feedback information on the selected feedback resource set.

It is easily understood that the different time slot intervals may cause the time domain resources contained in the first feedback resource set to collide with the time domain resources contained in the second feedback resource set. Therefore, optionally, the processing module is further configured to determine that the first time domain resource is only used for sending the feedback information of the first service if the first feedback resource set and the second feedback resource set both include the first time domain resource; the first service is a high-priority service and/or a low-transmission-delay service. The first service is a high-priority service and/or a low-transmission-delay service. That is, when the time domain resources included in the first feedback resource set and the second feedback resource set conflict, it may be preferentially ensured that the feedback information of the high priority service and/or the low transmission delay service is transmitted.

Optionally, the terminal device according to the third aspect may further include a storage module, where the storage module stores a program or an instruction. When the processing module executes the program or the instruction, the terminal device according to the third aspect may perform the function of the first terminal device in the method for configuring feedback resources according to the first aspect.

Fig. 3 is a flowchart illustrating a method for configuring feedback resources according to an embodiment of the present application. The method for configuring the feedback resource may be applied to communication between any two terminal apparatuses shown in fig. 1.

As shown in fig. 3, the method for configuring feedback resources includes the following steps:

s301, the network device transmits first configuration information to the first terminal device and the second terminal device, and the first terminal device and the second terminal device receive the first configuration information from the network device. The first configuration information is used for indicating at least two feedback resource sets, and the at least two feedback resource sets comprise a first feedback resource set and a second feedback resource set; the first set of feedback resources is different from the second set of feedback resources.

Illustratively, both sets of feedback resources described above may include one or more feedback resources. The feedback resource may be a radio resource available on the sidelink for carrying feedback information. The radio resources may include one or more of time domain resources, frequency domain resources, code domain resources, spatial domain resources, and power domain resources. Wherein, the frequency domain resource, such as an index of a Resource Block (RB), a number of RBs, a subchannel (subchannel) index, and an identification of the RB in the subchannel.

Specifically, the first feedback resource set and the second feedback resource set may include one or more of the following items, which are different: the time domain resources contained in the first feedback resource set are different from the time domain resources contained in the second feedback resource set; the frequency domain resources contained in the first feedback resource set are different from the frequency domain resources contained in the second feedback resource set; the code domain resources contained in the first feedback resource set are different from the code domain resources contained in the second feedback resource set; the spatial domain resources contained in the first feedback resource set are different from the spatial domain resources contained in the second feedback resource set; the first set of feedback resources comprises orthogonal sequences that are different from the orthogonal sequences comprised by the second set of feedback resources.

Then, for the first terminal device, after receiving the service data transmitted by the second terminal device, the following steps may be performed:

s302, the first terminal device and the second terminal device select the first feedback resource set or the second feedback resource set.

Wherein the first terminal device and the second terminal device select the first set of feedback resources or the second set of feedback resources based on the same method. That is, the set of feedback resources selected by the first terminal device and the set of feedback resources selected by the second terminal device are the same set of feedback resources. The specific implementation may refer to the following description, which is not repeated herein.

S303, the first terminal device sends feedback information on the selected set of feedback resources. Accordingly, the second terminal device receives feedback information on the selected set of feedback resources.

The following describes the difference between the first feedback resource set and the second feedback resource set and the processing manner when the first feedback resource set conflicts with the second feedback resource set in detail by taking time domain resources as an example.

In a possible design method, the time domain resources included in the first feedback resource set are different from the time domain resources included in the second feedback resource set, and the method may include:

the time slot interval between any two adjacent feedback resources in the first feedback resource set is the same as the time slot interval between any two adjacent feedback resources in the second feedback resource set, and the time slot offset of the first feedback resource set is different from the time slot offset of the second feedback resource set, so as to ensure that no conflict exists between the time domain resources contained in the first feedback resource set and the time domain resources contained in the second feedback resource set.

Exemplarily, fig. 4 is a first schematic diagram of a configuration pattern of a feedback resource provided in an embodiment of the present application. As shown in fig. 4, the time slot intervals of the feedback resources included in the first feedback resource set and the second feedback resource set are both 4, the time slot offset of the feedback resources included in the first feedback resource set is 0, and the time slot offset of the feedback resources included in the second feedback resource set is 1. For the first feedback resource set, the timeslot number of the candidate timeslot that can be occupied by the feedback resource may be: 0. 4, 8, 12, 16, and so on. Wherein, timeslot 4 may be used to carry feedback information corresponding to data transmitted on timeslots 0-3, timeslot 8 may be used to carry feedback information corresponding to data transmitted on timeslots 4-7, timeslot 12 may be used to carry feedback information corresponding to data transmitted on timeslots 8-11, and so on. For the second set of feedback resources, the slot number of the candidate slot that the feedback resource may occupy may be: 1. 5, 9, 13, 17, and so on. Wherein, timeslot 1 may be used to carry feedback information corresponding to data transmitted on timeslot 0, timeslot 5 may be used to carry feedback information corresponding to data transmitted on timeslots 1-4, timeslot 9 may be used to carry feedback information corresponding to data transmitted on timeslots 5-8, timeslot 13 may be used to carry feedback information corresponding to data transmitted on timeslots 9-12, and so on. That is, the first feedback resource set and the second feedback resource set occupy different time slots, respectively, and there is no conflict therebetween.

It should be noted that, the candidate timeslots of the feedback resources included in the first feedback resource set and the second feedback resource set may not be used for carrying feedback information, such as may be used for carrying data or idle. For example, as shown in fig. 4, for the first feedback resource set, although slot 0 is a candidate slot for the feedback resource, since slot 0 is the starting slot, no data needs to be transmitted before, it is not necessary to carry the feedback information on slot 0. It is easy to understand that, in order to improve resource utilization and communication efficiency, data may also be selected to be transmitted on the time slot 0, which is not limited in this embodiment of the application.

In another possible design method, the time domain resources included in the first feedback resource set and the time domain resources included in the second feedback resource set are different, and the method may include:

the time slot interval between any two adjacent feedback resources in the first feedback resource set is different from the time slot interval between any two adjacent feedback resources in the second feedback resource set.

Exemplarily, fig. 5 is a second schematic diagram of a configuration pattern of a feedback resource provided in the embodiment of the present application. As shown in fig. 5, the slot interval of the feedback resource included in the first feedback resource set is 4, the slot interval of the feedback resource included in the second feedback resource set is 3, and the slot offsets of the feedback resources included in the first feedback resource set and the first feedback resource set are both 0. For the first feedback resource set, the timeslot number of the candidate timeslot that can be occupied by the feedback resource may be: 0. 4, 8, 12, 16, and so on. Wherein, timeslot 4 may be used to carry feedback information corresponding to data transmitted on timeslots 0-3, timeslot 8 may be used to carry feedback information corresponding to data transmitted on timeslots 4-7, timeslot 12 may be used to carry feedback information corresponding to data transmitted on timeslots 8-11, and so on. For the second set of feedback resources, the slot number of the candidate slot that the feedback resource may occupy may be: 0. 3, 6, 9, 12, 15, 18, and so on. Wherein, the timeslot 3 may be used to carry feedback information corresponding to data transmitted on timeslots 0-2, the timeslot 6 may be used to carry feedback information corresponding to data transmitted on timeslots 3-5, the timeslot 9 may be used to carry feedback information corresponding to data transmitted on timeslots 6-8, and so on.

It should be noted that, the candidate timeslots of the feedback resources included in the first feedback resource set and the second feedback resource set may not be used for carrying feedback information, such as may be used for carrying data or idle. For example, as shown in fig. 5, in the first feedback resource set and the second feedback resource set, slot 0 is a candidate slot for a feedback resource, but since slot 0 is a starting slot, no data needs to be transmitted before, and therefore no feedback information needs to be carried on slot 0. It is easy to understand that, in order to improve resource utilization and communication efficiency, data may also be selected to be transmitted in time slot 0, which is not limited in the embodiment of the present application.

It is easy to understand that, since the first feedback resource set and the second feedback resource set include different time slot intervals of feedback resources, there may be a case where both the first feedback resource set and the second feedback resource set include the same time slot, that is, there may be a time slot collision between the first feedback resource set and the second feedback resource set.

In particular, in time slots s_iFor example, the first feedback resource set and the second feedback resource set may be determined in time slot s by the following method_jWhether there is a conflict:

if time slot s_iIf the following conditions are met, determining that the first feedback resource set and the second feedback resource set are in the time slot s_iAnd (3) collision:

(s_i-S₁)％T ₁0, and(s)_i-S₂)％T₂＝0。

Wherein s is_iNumbering the time slots of the ith time slot in the first feedback resource set and the second feedback resource set, T₁Is the first feedback dataThe source set comprises the slot interval, T, of the slots₂The interval of time slots, S, of time slots contained in the second set of feedback resources₁Is the slot offset, S, of the candidate slot comprised in the first set of feedback resources₂Is the slot offset of the candidate slot included in the second set of feedback resources.

Illustratively, T is shown in FIG. 5₁＝4，T₂＝3，S₁＝S₂If 0, the first and second feedback resource sets are in s_iA collision on a slot of 12.

Therefore, optionally, the time domain resources included in the first feedback resource set are different from the time domain resources included in the second feedback resource set, and the method may further include:

if the first feedback resource set and the second feedback resource set both include the first time domain resource, the first time domain resource is only used for transmitting the feedback information of the first service. The first service is a high-priority service and/or a low-transmission-delay service. That is, when the time domain resources included in the first feedback resource set conflict with the time domain resources included in the second feedback resource set, it may be guaranteed that the high priority service and/or the low transmission delay service are transmitted with priority. The first time domain resource may be a time slot 12 shown in fig. 5, and the time slot 12 is only used for transmitting the feedback information of the first service.

For example, as shown in fig. 5, assuming that a first set of feedback resources is used to carry feedback information of multicast (MC, which may be referred to as multicast) traffic, a second set of feedback resources is used to carry feedback information of unicast (uni-cast, UC) traffic, and the priority of the multicast traffic is higher than that of the unicast traffic, the timeslot 12 is only used to transmit the feedback information of the multicast traffic.

Meanwhile, for the feedback information of the low-priority service and/or the high-transmission-delay service, such as the feedback information of the unicast service, according to the actual situation, any one of the following methods may be used to process the feedback information:

assuming that the second set of feedback resources further includes a second time domain resource, the feedback information of the second service may be carried on the second time domain resource. That is to say, the feedback information of the second service originally transmitted on the first time domain resource may be placed on the second time domain resource for transmission, and the problem of resource conflict caused by transmission of both the feedback information of the first service and the feedback information of the second service on the first time domain resource may be solved.

In a possible design method, the first time domain resource may include a first time slot, the second time domain resource may include a second time slot, and the second time slot is located after the first time slot, and then the feedback information of the first service may be carried on the first time slot, and the feedback information of the second service may be carried on the second time slot. Further, in order to ensure timeliness of the feedback information of the second service as much as possible, the second time slot may be the next time slot of the first time slot.

Exemplarily, fig. 6 is a third schematic diagram of a configuration pattern of a feedback resource provided in the embodiment of the present application. Referring to fig. 4, as shown in fig. 6, the first time slot may be time slot 12, and the second time slot may be time slot 13.

Or, optionally, the first time domain resource and the second time domain resource may also respectively include different symbols in the same slot.

Exemplarily, fig. 7 is a fourth schematic diagram of a configuration pattern of a feedback resource provided in the embodiment of the present application. In conjunction with fig. 5, as shown in fig. 7, the first time domain resource and the second time domain resource may each include different symbols in the time slot 12, for example, the first time domain resource may include symbols 0 to 6 in the time slot 12, and the second time domain resource may include symbols 10 to 13 in the time slot 12.

Or, optionally, in view of the lower priority of the second service and/or the larger transmission delay, the feedback information of the second service that originally needs to be transmitted on the first time domain resource may not be transmitted any more, that is, the transmission of the feedback information of the second service that originally needs to be transmitted on the first time domain resource is abandoned.

Exemplarily, fig. 8 is a fifth schematic diagram of a configuration pattern of a feedback resource provided in an embodiment of the present application. With reference to fig. 5, as shown in fig. 8, the first time domain resource and the second time domain resource both include a time slot 12, and the time slot 12 is only used for transmitting the feedback information of the first service, and for the feedback information of the second service that originally needs to be transmitted in the time slot 12, the transmission is not performed. That is, for the second service, the transmission of the feedback information corresponding to the data transmitted on the time slots 9 to 11 is abandoned.

It should be noted that the feedback information of the second service related to the foregoing abandoning transmission scheme only refers to the feedback information of the second service that originally needs to be transmitted on the first time domain resource, and the feedback information of the second service that is transmitted on other time domain resources, except the first time domain resource, in the second feedback resource set and that does not collide with the time domain resource in the first feedback resource set still needs to be transmitted. Illustratively, as shown in fig. 8, feedback information for the second service originally transmitted on

time slots

3, 6, 9, 15, 18 still needs to be transmitted.

It should be noted that, in addition to the above technical solution for solving the conflict problem between the first feedback resource set and the second feedback resource set in the time domain, one or more of the following schemes may be adopted to solve the conflict problem between the first feedback resource set and the second feedback resource set:

the frequency domain resources contained in the first feedback resource set are different from the frequency domain resources contained in the second feedback resource set;

the code domain resources contained in the first feedback resource set are different from the code domain resources contained in the second feedback resource set;

the spatial domain resources contained in the first feedback resource set are different from the spatial domain resources contained in the second feedback resource set;

the first set of feedback resources comprises orthogonal sequences that are different from the orthogonal sequences comprised by the second set of feedback resources.

Exemplarily, fig. 9 is a sixth schematic diagram of a configuration pattern of a feedback resource provided in an embodiment of the present application. As shown in fig. 9, the first feedback resource set and the second feedback resource set both include first time domain resources, such as symbols 10-13 in a slot 12, that is, the symbols 10-13 of the first feedback resource set and the second feedback resource set collide in the slot 12, then a frequency domain subchannel 1 on the symbols 10-13 of the slot 12 may be configured for the first feedback resource set, and a frequency domain subchannel 2 on the symbols 10-13 of the slot 12 may be configured for the second feedback resource set.

For example, the orthogonal sequence included in the first feedback resource set is different from the orthogonal sequence included in the second feedback resource set, and the method may include:

the orthogonal sequence adopted by the feedback resource contained in the first feedback resource set is different from the orthogonal sequence adopted by the feedback resource contained in the second feedback resource set.

The orthogonal sequence adopted by the feedback resource can be an orthogonal sequence which satisfies the following conditions:

wherein N is_SFRepresents the length of the orthogonal sequence, i.e. the value of the Spreading Factor (SF) of the orthogonal sequence, N_SFThe corresponding orthogonal sequence can be regarded as an orthogonal sequence set, and the number of the orthogonal sequences contained in the orthogonal sequence set is equal to the N_SFThe value of (a). i is the number N_SFAnd m is the sequence number of the sequence value in the ith orthogonal sequence.

Table 1 is an example of the orthogonal sequence. When N is present as shown in Table 1_SFWhen the length of the orthogonal sequence is 6, the corresponding orthogonal sequence set includes 6 orthogonal sequences, i is 0,1,2,3,4, and 5. Wherein, i-1 corresponds to an orthogonal sequence of [ 012345 ]]And the sequence corresponding to m-2 takes a value of 2.

Optionally, referring to table 1, the orthogonal sequence included in the first feedback resource set is different from the orthogonal sequence included in the second feedback resource set, and the method may include: n is a radical of_SFThe same, i is different. That is, as long as the feedback resources use the same N_SFAnd different i, i.e. can be considered as different feedback resources.

For example, N employed by feedback resources in the first set of feedback resources_SFN adopted by feedback resources in the second feedback resource set_SFAll 7, and i of the feedback resource in the first feedback resource set is 0, and i of the feedback resource in the second feedback resource set is 5, so as to determine different orthogonal sequences.

In addition, the configurations of the time domain resources, the frequency domain resources, the code domain resources and the available resources may be performed independently or in combination, as long as at least one resource can be distinguished from each other.

In addition, the configuration patterns of the various feedback resources shown in fig. 4 to 9 may all be configuration patterns in the same configuration period, and in different configuration periods, the first feedback resource set and the second feedback resource set may all adopt the same configuration. Therefore, optionally, both the first feedback resource set and the second feedback resource set may be feedback resource sets in the same configuration period. Wherein one configuration period may include a plurality of consecutive time slots.

Further, the first set of feedback resources and the second set of feedback resources may be configured separately in the same configuration period.

Still further, the first feedback resource set is the same in two adjacent configuration periods, and the second feedback resource set is the same in two adjacent configuration periods.

Exemplarily, fig. 10 is a seventh schematic diagram of a configuration pattern of a feedback resource provided in an embodiment of the present application. As shown in fig. 10, the configuration periods of the first feedback resource set and the second feedback resource set are both 16 timeslots, and in the same configuration period, both the first feedback resource set and the second feedback resource set can be configured independently. As shown in fig. 10, in both the configuration period P1 and the configuration period P2, the slot interval of the feedback resources included in the first feedback resource set is 4, the slot offset is 0, the slot interval of the feedback resources included in the second feedback resource set is 3, and the slot offset is 1. That is, for the first feedback resource set, the slot number of the candidate slot that the feedback resource may occupy may be: 0. 4, 8 and 12. Wherein, timeslot 4 may be used to carry feedback information corresponding to data transmitted on timeslots 0-3, timeslot 8 may be used to carry feedback information corresponding to data transmitted on timeslots 4-7, and timeslot 12 may be used to carry feedback information corresponding to data transmitted on timeslots 8-11. For the second set of feedback resources, the slot number of the candidate slot that the feedback resource may occupy may be: 1. 4, 7, 10 and 13. Wherein, timeslot 1 may be used to carry feedback information corresponding to data transmitted on timeslot 0, timeslot 4 may be used to carry feedback information corresponding to data transmitted on timeslots 1-3, timeslot 7 may be used to carry feedback information corresponding to data transmitted on timeslots 4-6, timeslot 10 may be used to carry feedback information corresponding to data transmitted on timeslots 7-9, and timeslot 13 may be used to carry feedback information corresponding to data transmitted on timeslots 10-12.

It should be noted that, because the feedback resources are configured according to the configuration period, the feedback resources in a certain configuration period are not generally used for carrying feedback information corresponding to data transmitted on a timeslot at the end of the last configuration period. Therefore, for data transmitted on a partial timeslot at the tail end of the configuration period, there may not be a feedback resource for carrying feedback information corresponding to the data. Illustratively, as shown in fig. 10, for the first set of feedback resources, for the data transmitted on time slot 13-time slot 15 in the configuration period P1, there is no feedback resource for carrying the feedback information corresponding to the data. Similarly, for the second feedback resource set, no feedback resource for carrying feedback information corresponding to the data exists for the data transmitted on the timeslot 14-timeslot 15 in the configuration period P1, and for the timeslot without the feedback resource, the terminal adopts a default HARQ disabling method when transmitting the data, that is, does not feed back the HARQ-ACK information.

The method for configuring feedback resources provided by the embodiments of the present application is described in detail above with reference to fig. 3 to fig. 10. The terminal device provided by the embodiment of the present application is described in detail below with reference to fig. 11.

Fig. 11 is a schematic structural diagram of a terminal device according to an embodiment of the present application. The terminal device 1100 shown in fig. 11 is applicable to the communication system shown in fig. 1, and performs the function of the first terminal device in the method for configuring the feedback resource shown in fig. 3. For convenience of explanation, fig. 11 shows only main components of the terminal apparatus 1100.

As shown in fig. 11, the terminal apparatus 1100 includes: a processing module 1101 and a transceiver module 1102.

The transceiver module 1102 is configured to receive first configuration information from a network device. The first configuration information is used for indicating at least two feedback resource sets, and the at least two feedback resource sets comprise a first feedback resource set and a second feedback resource set; the first set of feedback resources is different from the second set of feedback resources. A processing module 1101 configured to select a first set of feedback resources or a second set of feedback resources. The transceiving module 1102 is further configured to transmit feedback information on the selected feedback resource set.

It is easily understood that the different time slot intervals may cause the time domain resources contained in the first feedback resource set to collide with the time domain resources contained in the second feedback resource set. Therefore, optionally, the processing module 1101 is further configured to determine that the first time domain resource is only used for sending the feedback information of the first service if the first feedback resource set and the second feedback resource set both include the first time domain resource; the first service is a high-priority service and/or a low-transmission-delay service. The first service is a high-priority service and/or a low-transmission-delay service. That is, when the time domain resources included in the first feedback resource set and the second feedback resource set conflict, it may be preferentially ensured that the feedback information of the high priority service and/or the low transmission delay service is transmitted.

Optionally, the terminal device 1100 shown in fig. 11 may further include a storage module (not shown in fig. 11) that stores programs or instructions. The program or instructions, when executed by the processing module 1101, enable the terminal device 1100 shown in fig. 11 to perform the functions of the first terminal device in the above-described method embodiments.

A processing module 1101 configured to select a first set of feedback resources or a second set of feedback resources. The transceiver module 1102 is further configured to receive feedback information on the selected set of feedback resources.

It is easily understood that the different time slot intervals may cause the time domain resources contained in the first feedback resource set to collide with the time domain resources contained in the second feedback resource set. Therefore, optionally, the processing module 1101 is further configured to determine that the first time domain resource is only used for receiving the feedback information of the first service if the first feedback resource set and the second feedback resource set both include the first time domain resource. The first service is a high-priority service and/or a low-transmission-delay service.

Optionally, the terminal device 1100 shown in fig. 11 may further include a storage module (not shown in fig. 11) that stores programs or instructions. The program or instructions, when executed by the processing module 1101, enable the terminal device 1100 shown in fig. 11 to perform the functions of the second terminal device in the above-described method for configuring feedback resources shown in fig. 3.
