Description

Feedback resource configuration method and terminal device

This application claims the priority of the Chinese patent application filed with the State Intellectual Property Office on June 14, 2019, the application number is 201910517343.8, and the application name is "Feedback Resource Configuration Method and Terminal Device", the entire content of which is incorporated into this by reference Applying.

Technical field

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

Background technique

At present, in the process of communication between terminal devices on the sidelink (SL), service data, such as unicast (UC) data or multicast (multi-cast, MC) data, is in the service channel , Such as transmission on the physical sidelink shared channel (PSSCH), the feedback information corresponding to the service data, such as the acknowledgement (ACK) or negative of the hybrid automatic repeat request (HARQ) Acknowledgement (non-acknowledgement, NACK), channel quality information (channel quality information, CQI), etc., are transmitted on a feedback channel, such as a physical sidelink feedback channel (PSFCH). In addition, in order to improve the transmission efficiency of feedback information, feedback information corresponding to service data of multiple slots (slots) in the same slot interval is usually concentrated in one feedback slot for transmission. For example, assuming that the time slot interval can be configured to 4 and the offset of the feedback time slot is 0, the feedback information corresponding to the service data transmitted in time slot 0 to time slot 3 is transmitted in time slot 4.

However, for different services, the time slot interval between the above feedback time slots is usually the same value and is pre-configured. It cannot be dynamically indicated by signaling, and cannot be applied to services with different delay requirements, nor is it suitable for feedback. Businesses with different amounts of information have poor flexibility.

The first configuration information is used to indicate at least two feedback resource sets. The at least two feedback resource sets include a first feedback resource set and a second feedback resource set; the first feedback resource set is different from the second feedback resource set. Then, the first terminal device selects the first feedback resource set or the second feedback resource set, and sends feedback information on the selected feedback resource set.

According to the feedback resource configuration method provided by the embodiment of the present application, the first terminal device can select different feedback resource sets from at least two feedback resource sets indicated by the first configuration information according to the data volume and/or feedback delay of the feedback information of different services. The feedback resource set, such as the first feedback resource set or the second feedback resource set mentioned above, can avoid using the pre-configured time interval between the same feedback resource to send feedback information of different services due to the data volume of the feedback information of different services Different or different transmission delays required for feedback information lead to insufficient or wasted feedback resources, and the transmission delay of feedback information cannot meet the delay requirements. This can improve the efficiency and flexibility of the configuration of feedback resources, thereby improving the transmission of feedback information. effectiveness.

As shown in Figure 4, the time slot interval of the feedback resources included in the first feedback resource set and the second feedback resource set is 4, and the time slot offset of the feedback resources included in the first feedback resource set is 0, and the second The time slot offset of the feedback resource included in the feedback resource set is 1. Wherein, for the first feedback resource set, the slot numbers of candidate slots that can be occupied by the feedback resources may be: 0, 4, 8, 12, 16, and so on. Among them, time slot 4 can be used to carry the feedback information corresponding to the data transmitted in time slot 0 to time slot 3, and time slot 8 can be used to carry the feedback information corresponding to the data transmitted in time slot 4 to time slot 7. 12 can be used to carry the feedback information corresponding to the data transmitted on time slot 8-time slot 11, and so on. For the second feedback resource set, the slot numbers of candidate slots that can be occupied by the feedback resources may be: 1, 5, 9, 13, 17, and so on. Among them, time slot 1 can be used to carry the feedback information corresponding to the data transmitted in time slot 0, time slot 5 can be used to carry the feedback information corresponding to data transmitted in time slot 1 to time slot 4, and time slot 9 can be used to carry The feedback information corresponding to the data transmitted in time slot 5 to time slot 8, and time slot 13 can be used to carry the feedback information corresponding to the data transmitted in time slot 9 to time slot 12, and so on. In other words, the first feedback resource set and the second feedback resource set occupy different time slots, and there is no conflict between them.

It should be noted that the candidate time slots of the feedback resources included in the first feedback resource set and the second feedback resource set may not be used to carry feedback information, for example, may be used to carry data or be idle. For example, as shown in Figure 4, for the first feedback resource set, although time slot 0 is a candidate time slot for the feedback resource, since time slot 0 is the starting time slot, there is no data to be transmitted before, so there is no need to be in time The feedback information is carried on slot 0. It is easy to understand that in order to improve resource utilization and communication efficiency, data can also be transmitted in time slot 0, which is not limited in the embodiment of the present application.

In another 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, which 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 feedback resources provided by an embodiment of the application. As shown in Figure 5, the time slot interval of the feedback resources included in the first feedback resource set is 4, the time slot interval of the feedback resources included in the second feedback resource set is 3, and the first feedback resource set and the first feedback resource set The time slot offsets of the included feedback resources are all 0. Wherein, for the first feedback resource set, the slot numbers of candidate slots that can be occupied by the feedback resources may be: 0, 4, 8, 12, 16, and so on. Among them, time slot 4 can be used to carry the feedback information corresponding to the data transmitted in time slot 0 to time slot 3, and time slot 8 can be used to carry the feedback information corresponding to the data transmitted in time slot 4 to time slot 7. 12 can be used to carry the feedback information corresponding to the data transmitted on time slot 8-time slot 11, and so on. For the second feedback resource set, the slot numbers of candidate slots that can be occupied by feedback resources can be: 0, 3, 6, 9, 12, 15, 18, and so on. Among them, time slot 3 can be used to carry feedback information corresponding to the data transmitted in time slot 0-time slot 2, and time slot 6 can be used to carry feedback information corresponding to data transmitted in time slot 3 to time slot 5. 9 can be used to carry feedback information corresponding to the data transmitted in time slot 6 to time slot 8, and so on.

It should be noted that the candidate time slots of the feedback resources included in the first feedback resource set and the second feedback resource set may not be used to carry feedback information, for example, may be used to carry data or be idle. Exemplarily, as shown in FIG. 5, although time slot 0 is a candidate time slot for feedback resources in the first feedback resource set and the second feedback resource set, since time slot 0 is the starting time slot, the previous combination No data needs to be transmitted, so there is no need to carry feedback information on slot 0. It is easy to understand that in order to improve resource utilization and communication efficiency, data may also 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 time slot intervals of the feedback resources contained in the first feedback resource set and the second feedback resource set are different, there may be a situation where the first feedback resource set and the second feedback resource set both contain the same time slot, that is, the first feedback There may be a time slot conflict between the resource set and the second feedback resource set.

Specifically, taking time slot s _i as an example, the following method can be used to determine whether the first feedback resource set and the second feedback resource set conflict in time slot s _j :

If the time slot s _i meets the following conditions, it is determined that the first feedback resource set and the second feedback resource set conflict on the time slot s _i :

(s _i -S ₁ )%T ₁ =0, and (s _i -S ₂ )%T ₂ =0.

Where s _i is the slot number of the i-th slot in the first feedback resource set and the second feedback resource set, T ₁ is the slot interval of the slot included in the first feedback resource set, and T ₂ is the second The time slot interval of the time slot contained in the feedback resource set, S ₁ is the time slot offset of the candidate time slot contained in the first feedback resource set, and S ₂ is the time slot offset of the candidate time slot contained in the second feedback resource set the amount.

Exemplarily, as shown in Figure 5, T ₁ = 4, T ₂ = 3, S ₁ = S ₂ =0, then the first feedback resource set and the second feedback resource set collide on the time slot of s _i =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 may further include:

If both the first feedback resource set and the second feedback resource set include the first time domain resource, the first time domain resource is only used to transmit the feedback information of the first service. Among them, 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, the transmission of high-priority services and/or the feedback information of low-transmission-delay services can be given priority. . Among them, the first time domain resource may be the time slot 12 shown in FIG. 5, and the time slot 12 is only used to transmit feedback information of the first service.

Exemplarily, as shown in FIG. 5, it is assumed that the first feedback resource set is used to carry feedback information of a multicast (multicast, MC, also known as multicast) service, and the second feedback resource set is used to carry unicast (unicast) service feedback information. -cast, UC) service feedback information, and the priority of the multicast service is higher than the priority of the unicast service, then the time slot 12 is only used to transmit the feedback information of the multicast service.

At the same time, feedback information for low-priority services and/or high-delay services, such as the feedback information for unicast services described above, can be processed in any of the following ways depending on the actual situation:

Assuming that the second feedback resource set further includes the second time domain resource, the second service feedback information may be carried on the second time domain resource. In other words, the feedback information of the second service originally transmitted on the first time domain resource can be placed on the second time domain resource for transmission, which can solve that the feedback information of the first service and the feedback information of the second service are both in The resource conflict problem caused by the transmission on the first time domain resource.

In a possible design method, the first time domain resource may include the first time slot, the second time domain resource may include the second time slot, and the second time slot is located after the first time slot, it may be in the first time slot. The time slot carries the feedback information of the first service, and the second time slot carries the feedback information of the second service. Further, in order to ensure the 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 feedback resources provided by an embodiment of the application. With reference 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 include different symbols in the same time slot.

Exemplarily, FIG. 7 is a fourth schematic diagram of a configuration pattern of feedback resources provided by an embodiment of the application. With reference to FIG. 5, as shown in FIG. 7, both the first time domain resource and the second time domain resource may include different symbols in time slot 12. For example, the first time domain resource may include symbols 0 to symbol 6 in time slot 12. , The second time domain resource may include symbol 10-symbol 13 in time slot 12.

Or, optionally, given that the priority of the second service is low, and/or the transmission delay is relatively large, the feedback information of the second service that originally needs to be transmitted on the first time domain resource may not be transmitted, that is, Give up transmitting the feedback information of the second service that originally needs to be transmitted on the first time domain resource.

Exemplarily, FIG. 8 is a fifth schematic diagram of a configuration pattern of feedback resources provided by an embodiment of the application. With reference to Figure 5, as shown in Figure 8, the first time domain resource and the second time domain resource both include time slot 12. Then time slot 12 is only used to transmit the feedback information of the first service. The feedback information of the second service is no longer transmitted. That is to say, for the second service, the feedback information corresponding to the data transmitted in time slot 9 to time slot 11 is abandoned.

It should be noted that the feedback information of the second service involved in the foregoing abandonment of the transmission scheme only refers to the feedback information of the second service that originally needed to be transmitted on the first time domain resource. The feedback information of the second service transmitted on other time domain resources that do not conflict with the time domain resources in the first feedback resource set other than the time domain resources still needs to be transmitted. Exemplarily, as shown in FIG. 8, the feedback information of the second service originally transmitted in

time slots

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

It should be noted that, in addition to the above-mentioned 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 solutions may also be adopted: Conflict between the second feedback resource collection:

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

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

The airspace resources included in the first feedback resource set are different from the airspace resources included in the second feedback resource set;

The orthogonal sequence included in the first feedback resource set is different from the orthogonal sequence included in the second feedback resource set.

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

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

The orthogonal sequence used by the feedback resources included in the first feedback resource set is different from the orthogonal sequence used by the feedback resources included in the second feedback resource set.

Among them, the orthogonal sequence used by the feedback resource may be an orthogonal sequence that satisfies the following conditions:

Among them, N _SF represents the length of the orthogonal sequence, which is the value of the spreading factor (SF) of the orthogonal sequence. An orthogonal sequence corresponding to an N _SF can be regarded as an orthogonal sequence set. The number of orthogonal sequences contained in the sequence set is equal to the value of the N _SF . i is the sequence number of the orthogonal sequence contained in the orthogonal sequence set corresponding to the N _SF , and m is the sequence number of the sequence value in the i-th orthogonal sequence.

Table 1 is an example of the orthogonal sequence. As shown in Table 1, when N _SF =6, the corresponding orthogonal sequence set includes a total of 6 orthogonal sequences, i=0,1,2,3,4,5, and the length of each orthogonal sequence is equal For 6. Among them, the orthogonal sequence corresponding to i=1 is [012345], and the value corresponding to m=2 is 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, which may include: N _{SF is the} same and i is different. In other words, as long as the feedback resources adopt the same N _SF and different i, they can be regarded as different feedback resources.

For example, N _SF first feedback resource set employed in the second feedback resource in the feedback resource set used feedback resources are N _SF 7, and the first set of feedback resource in the feedback resource using i = 0, the first 2. The feedback resource in the feedback resource set adopts i=5 to determine different orthogonal sequences.

Table 1

In addition, the above-mentioned configuration of time domain resources, frequency domain resources, code domain resources and available resources can 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 Figures 4-9 can all be configuration patterns in the same configuration period, and in different configuration periods, both the first feedback resource set and the second feedback resource set can be used. Use 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. Among them, one configuration period may include multiple consecutive time slots.

Further, the first feedback resource set and the second feedback resource set may be separately configured 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 feedback resources provided by an embodiment of the application. As shown in Figure 10, the configuration periods of the first feedback resource set and the second feedback resource set are both 16 time slots, and within the same configuration period, the first feedback resource set and the second feedback resource set can be independently configured . As shown in Figure 10, regardless of the configuration period P1 or the configuration period P2, the time slot interval of the feedback resources included in the first feedback resource set is 4, the time slot offset is 0, and the second feedback resource set contains The time slot interval of the feedback resource is 3, and the time slot offset is 1. That is, for the first feedback resource set, the slot numbers of candidate slots that can be occupied by the feedback resources may be: 0, 4, 8, and 12. Among them, time slot 4 can be used to carry the feedback information corresponding to the data transmitted in time slot 0 to time slot 3, and time slot 8 can be used to carry the feedback information corresponding to the data transmitted in time slot 4 to time slot 7. 12 can be used to carry feedback information corresponding to the data transmitted on time slot 8 to time slot 11. For the second feedback resource set, the slot numbers of candidate slots that can be occupied by feedback resources may be: 1, 4, 7, 10, 13. Among them, time slot 1 can be used to carry the feedback information corresponding to the data transmitted in time slot 0, time slot 4 can be used to carry the feedback information corresponding to data transmitted in time slot 1 to time slot 3, and time slot 7 can be used to carry The feedback information corresponding to the data transmitted in time slot 4 to time slot 6, time slot 10 can be used to carry the feedback information corresponding to the data transmitted in time slot 7 to time slot 9, and time slot 13 can be used to carry feedback information in time slot 10. -Feedback information corresponding to the data transmitted on time slot 12.

It should be noted that since the feedback resources are configured according to the configuration period, the feedback resources in a certain configuration period are generally not used to carry the feedback information corresponding to the data transmitted in the time slot at the end of the previous configuration period. Therefore, for the data transmitted on part of the time slots at the end of the configuration period, there may not be feedback resources for carrying feedback information corresponding to the data. Exemplarily, as shown in FIG. 10, for the first feedback resource set, there is no feedback resource for carrying feedback information corresponding to the data transmitted in the time slot 13 to the time slot 15 in the configuration period P1. In the same way, for the second feedback resource set, the data transmitted in time slot 14 to time slot 15 in the configuration period P1 does not have a feedback resource for carrying the feedback information corresponding to the data. When there is no feedback resource Slot, the terminal uses the default HARQ disabling method when transmitting data, that is, it does not feed back HARQ-ACK information.

The processing module 1101 is configured to select the first feedback resource set or the second feedback resource set. The transceiver module 1102 is also used to receive feedback information on the selected feedback resource set.

It is easy to understand that the above-mentioned time slot interval is different, which may cause the time domain resources included in the first feedback resource set to conflict with the time domain resources included in the second feedback resource set. Therefore, optionally, the processing module 1101 is further configured to, if both the first feedback resource set and the second feedback resource set include the first time domain resource, determine that the first time domain resource is only used to receive feedback information of the first service . Among them, the first service is a high priority service and/or a low transmission delay service.
