The present application claims priority to Chinese Patent Application No. 201710548121.3, filed on Jan. 6, 2017, the entire content of

Technical field

The embodiments of the present disclosure relate to the field of communications technologies, and in particular, to a resource selection method, apparatus, and terminal.

Background technique

In the Long Term Evolution (LTE) system of the universal mobile communication technology, the R14 cellular vehicle networking technology standard in vehicle communication stipulates that the vehicle equipment (UE, User Equipment) first selects the transmission resource according to the perceived resource. In the occupancy situation, resources that have been occupied by other UEs are excluded from the resource selection window. Then, the UE sorts the remaining resource strength indication (RSSI, Received Signal Strength Indication) to obtain a set of available resources. Finally, the UE randomly selects its own transmission resource from the set of available resources.

The R14 standard considers the priority of the service in the sensing process. Under the condition that the scheduling assignment (SA, Scheduling Assignment) indicates that the information is successfully decoded, the resources occupied by the high-priority data packet are excluded from the low-priority data packet. More likely. This takes into account the priority of the reception to a certain extent, but this reception is a positive reception, that is, the reception is determined because the received SA indication information indicates the location of the corresponding data packet. This affirmative reception is available in periodic services, but if an event-triggered service occurs, such a positive reception will not necessarily be known. In this way, when the UE selects resources for other services or decides whether to send on the selected resources, it cannot refer to and exclude these affirmative receiving resources. In addition, due to the limitation of half-duplex, once a resource is selected to send other services, the ability to send and receive event-triggered services in the time domain of the resource is lost.

With the improvement of the level of intelligent driving, there are more and more types of event-triggered services. Especially in scenarios where multiple UEs need to form collaborative decisions based on multiple information interactions, the UE needs to know the required transmission and reception resources in advance, and In the process of selecting the sending resource, one (some) link of the collaborative decision caused by the half-duplex effect cannot successfully send and receive data. It is very important that the correct transmission and reception of each step of the information in the general decision reference information is related to the final decision.

However, in the related art, under the half-duplex restriction, for the service that the UE participates in, the UE may miss sending or receiving the data packet of the participating service because of the lower priority service or the service that does not need to perform multiple coordinated services. As a result, the participating business cannot go smoothly. In reality, however, the participating business may be more important than the lower priority service or the business that does not require multiple collaborations.

Detailed ways

The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure. It is obvious that the described embodiments are a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the embodiments of the present disclosure.

Referring to FIG. 1 , an embodiment of the present disclosure provides a resource selection method, which is applied to a terminal, and includes:

Step 101: Determine a resource set related to the first service that the terminal participates in;

Step 102: Prohibit sending data packets of other services except the first service in a time domain or a time-frequency domain corresponding to each resource in the resource set.

For example, the execution subject terminal involved in the embodiment of the present disclosure is specifically a vehicle terminal related to the first service participating in the first service. The time-frequency domain corresponding to each resource in the resource set may be the time-frequency domain actually corresponding to the resource, or may be a time-frequency domain including the time-frequency domain actually corresponding to the resource and larger than the time-frequency domain actually corresponding to the resource. Domain scope. For example, the time-frequency domain range is the time domain in which the resource actually corresponds to the time domain, and the frequency domain range including the frequency domain actually corresponding to the resource is the frequency domain. When determining the time-frequency domain range corresponding to the resource, the terminal may determine according to the preset condition of the terminal, for example, according to the size of the time-frequency domain specified by the terminal, or may determine according to the protocol agreement, or comprehensively consider the terminal capability ( For example, the terminal capability can be determined under certain frequency domain isolation conditions, simultaneously transmitting multiple services and/or simultaneously transmitting and receiving services, network requirements, service requirements, communication methods, and the like. Here, those skilled in the art can understand that the embodiments of the present disclosure do not limit the specific determination manner of the time-frequency domain range.

In this way, the resource selection method according to the embodiment of the present disclosure prohibits, for the first service that the terminal participates, by determining the resource set related to the first service, in the time domain or the time-frequency domain corresponding to each resource in the determined resource set. Sending data packets of other services except the first service, so that data packets of other services are not sent in the time domain or the time-frequency domain corresponding to each resource in the first service-related resource set, thereby avoiding the terminal Under the restriction of half-duplex, the data packet of the first service is abandoned or cannot be received due to the influence of other services, thereby finally ensuring the smooth participation of the terminal in the business.

It is noted that, for a terminal that does not participate in the first service but may affect the first service, for example, a terminal whose distance from any terminal related to the first service is less than a preset threshold, and/or receives any terminal related to the first service. a terminal that transmits a signal with a received power greater than a preset threshold, and/or any terminal associated with the first service receives a terminal whose received power of the transmitted signal is greater than a preset threshold, and/or a terminal that shares the transmission resource pool with the first service When selecting a resource for other services, the resource set related to the first service is also considered, and the resources in the time domain or the time-frequency domain corresponding to each resource in the resource set related to the first service are avoided as much as possible. The preset threshold value is, for example, 1 meter, 2 meters, etc., and may be preset according to a specific service type in the vehicle communication, as long as the distance between the two terminals is less than the preset threshold, one of the terminals is transmitting the data packet. It will affect the other terminal.

In a specific embodiment of the present disclosure, the first service may be selected as a service that requires multiple collaborations. In this way, when the terminal participates in the service that needs to cooperate multiple times, the data set related to the service is determined, and the data packet of the other service is not sent in the time domain or the time-frequency domain corresponding to each resource in the determined resource set. Therefore, it can be ensured that the terminal does not give up or cannot receive the data packet of the service requiring multiple cooperation due to the influence of other services, thereby avoiding the cooperative interaction failure of the service requiring multiple cooperation.

It should be noted that when the first service is a service that requires multiple cooperation, the number of terminals involved in the first service should be greater than or equal to two. And the first service does not only involve the interaction between the terminals related to the first service, that is, the relevant terminal needs to send and receive, and the relevant terminal only sends but does not receive, or the related terminal only receives but does not send, and these situations can be attributed to the first The collaborative scope of the business. The first service-related terminal may perform communication by means of broadcast, multicast, unicast, etc., which is not limited by the embodiment of the present disclosure.

In the following, the resource selection method of the embodiment of the present disclosure is described by taking the other service as the second service as an example. However, it is noted that the specific embodiment of the present disclosure does not limit the specific type of the service.

In a specific embodiment of the present disclosure, when the terminal selects the sending resource of the data packet of the second service according to the resource related to the first service, the terminal may be classified into the following two situations:

Case 1: when the terminal participates in the first service, the terminal selects a sending resource for the data packet of the second service;

Case 2: The terminal participates in the first service when the transmission resource has been selected for the data packet of the second service.

In a case, the terminal may select a data packet of the second service in the terminal resource other than the resource in the time domain or the time-frequency domain corresponding to each resource in the resource set related to the first service. In case 2, the terminal may overlap according to the time domain or the time-frequency domain corresponding to the at least one resource in the first service-related resource set and the time-frequency domain corresponding to the transmission resource selected for the data packet of the second service. Selecting to abandon all the transmission resources of the data packet of the second service, or discarding all or part of the transmission resources in the overlapping time-frequency domain of the data packet of the second service, or triggering the resource of the second service selected. The resource reselection process of the second service may be corresponding to the first case, that is, selecting, in the terminal resource, other resources except the resources in the time domain or the time-frequency domain corresponding to each resource in the resource set related to the first service. The second business packet.

Specifically, in the embodiment of the present disclosure, in the case, the foregoing step 101 may include:

Obtaining a sending resource related to the first service;

Determining a set of resources related to the first service.

Correspondingly, the foregoing step 102 may include:

The first service related resource set is the acquired set of the first service related transmission resource when the first service is a single transmission. When the first service has a retransmission, if all the transmission resources related to the first service are acquired, the first service related resource set is at least one transmission resource of each terminal related to the first service. And the collection of the first service-related resource set is the at least one transmission resource of each terminal of the obtained terminal corresponding to the partial transmission resource, if the collection of the first service-related partial transmission resource is obtained. Collection.

In the embodiment of the present disclosure, the manner in which the terminal acquires the sending resource related to the first service may be:

Acquiring the first service related transmission resource through high layer signaling; and/or

The signaling related to the first service is obtained by using signaling sent by the third-party management entity.

It should be understood that the manner in which the terminal acquires the transmission resource related to the first service is related to the selection manner of the transmission resource related to the first service. For example, the transmission resource selected by the terminal for itself may be obtained through high-level signaling, and the third-party management entity is the terminal. The selected transmission resource can be obtained by signaling sent by a third-party management entity, and the like. The third-party management entity is, for example, a base station in a network, a roadside unit of a highway, a control unit of the transportation department, a terminal having scheduling capability irrelevant to the first service, and the like.

For example, in the specific example 1 of the present disclosure, the UE1 participates in the service B (corresponding to the first service) when the transmission resource is selected for the data packet of the service A (corresponding to the second service), that is, the triggering time t1 of the service B is early. At the triggering time t2 of the service A, the service B is a service that needs to cooperate multiple times, and there are three vehicle terminals related to the service B, which are UE1, UE2, and UE3, respectively.

When the service B is a single transmission, as shown in FIG. 2, all the transmission resources related to the service B include the transmission resource 1 of the UE1, the transmission resource 2 of the UE2, and the transmission resource 3 of the UE3. At this time, if the UE1 obtains all the transmission resources related to the service B, the resource set related to the service B determined by the UE1 is the set of the transmission resources of all the terminals related to the service B, that is, the transmission resource 1 of the UE1, and the transmission resource 2 of the UE2. And a set of transmission resources 3 of UE3. If the UE1 obtains the partial transmission resources related to the service B, for example, the transmission resource 1 of the UE1 and the transmission resource 3 of the UE3, the resource set related to the service B determined by the UE1 is the transmission resource 1 of the UE1 and the transmission resource 3 of the UE3. . In this case, referring to FIG. 2, corresponding to the UE1 acquiring all the transmission resources related to the service B, the UE1 may select the resources related to the service B in the resource selection window of the service A when selecting the transmission resource for the data packet of the service A. All the resources other than the resources in the time domain corresponding to each of the transmission resources in the set send the data packet of the service A, so as to avoid the transmission resource 1 of the UE1, the transmission resource 2 of the UE2, and the time domain T0 of the transmission resource 3 of the UE3. All resources, because UE1 wants to send the data packet of service B on the transmission resource 1, and receives the data packets from the service B of UE2 and UE3 on the transmission resource 2 and the transmission resource 3, respectively.

When the service B has a retransmission, the retransmission is performed twice (but not limited to twice, or may be 1 or N times, and N is greater than 2). For example, all the transmission resources related to the service B may include the initial transmission resource of the UE1. 1 (that is, the transmission resource of the data packet of the first transmission service B of the UE1), the transmission resource one weight 1 (that is, the transmission resource of the data packet of the first retransmission service B of the UE1) and the transmission resource double 1 (that is, the second weight of the UE1) The transmission resource of the data packet of the service B), the transmission resource 2 of the UE2, the transmission resource 1 and the transmission resource 2, and the transmission resource 3 of the UE3, the transmission resource 3, and the transmission resource 2, a total of nine Send resources. At this time, if the UE1 acquires all the transmission resources related to the service B, the resource set related to the service B determined by the UE1 is a set of at least one transmission resource of each terminal related to the service B, that is, at least one transmission resource of the UE1, and the UE2 At least one transmission resource and a set of at least one transmission resource of UE3. For example, the service B-related resource set may include the foregoing nine transmission resources, or include the first transmission resource of the UE1, the transmission resource of the UE2, and the transmission resource of the UE3, or the first of the transmission resources of the UE1, and the UE1. The transmission resource is 1.1, the transmission resource 2 of the UE2 and the transmission resource of the UE3 are 3, or the transmission resource 1 of the UE1, the transmission resource 1 of the UE2, and the transmission resource of the UE3 are 3, and so on. That is to say, the resource set related to the service B only needs to include at least one transmission resource of each related terminal. If the UE1 obtains some of the transmission resources related to the service B, for example, the transmission resource primary 1 and the transmission resource one-to-one of the UE1, and the transmission resource primary 2 and the transmission resource-weight 2 of the UE2, the resource set related to the service B determined by the UE1 is The at least one transmission resource of each terminal in the terminal corresponding to the resource, that is, the at least one transmission resource of the UE1 and the at least one transmission resource of the UE2, and the resource set related to the service B determined by the UE1 may be the UE1. Sending a set of the first 2 transmission resources of the resource 1 and the UE2, or a set of the transmission resource 1 of the UE1 and the transmission resource 1 of the UE2, or the transmission resource 1 of the UE1, and the transmission resource 2 and the transmission resource of the UE2 2 collections, etc.

In this case, when selecting the transmission resource for the data packet of the service A, the UE1 may select other resources in the time domain corresponding to each of the transmission resources related to the service B in the resource selection window of the service A. The resource sends the data packet of the service A to avoid the resources in the time domain corresponding to the resource set related to the service B.

In order to avoid the frequency division multiplexing FDM with the primary retransmission transmission resource of the service B, optionally, when determining the resource set related to the service B, the resource set related to the service B may include the first transmission resource of the UE1. One of the transmission resource 1 and the transmission resource 2, the transmission resource 2 of the UE 2, the transmission resource 1 and the transmission resource 2, and the transmission resource 3 of the UE 3 and the transmission resource 3 Transmitting one of the resource triples 3 to avoid a certain resource for transmitting the data packet of the service B of the UE1 when the transmission resource is selected for the data packet of the service A, and a certain service B for receiving the service B of the UE2 The resource of the data packet, and a resource of a data packet for receiving the service B of the UE3, thereby avoiding the FDM of the initial retransmission transmission resource related to the service B.

It should be noted that, in the foregoing example 1, when the UE1 selects a transmission resource for the data packet of the service A, the UE1 avoids the resource in the time domain corresponding to each of the resource collections related to the service B. However, in addition to the avoidance mode, in other examples, the UE1 may also avoid resources in the time-frequency domain corresponding to each of the transmission resources related to the service B, or avoid the resources in the resource set related to the service B. The resource in the time domain corresponding to the part of the sending resource and the resource in the time-frequency domain corresponding to the other part of the sending resource are the same as the first embodiment, and are not described here. The time-frequency domain corresponding to the transmission resource may be the time-frequency domain corresponding to the actual transmission resource, or may be the time-frequency domain range corresponding to the transmission resource. Specifically, the time-frequency domain range corresponding to the sending resource may be determined according to a preset condition of the terminal, a protocol, or a capability of the UE1.

In addition, in the embodiment of the present disclosure, in the case, the above step 101 may further include:

Obtaining a sending resource related to the first service;

Evaluating a duration and a frequency range of the first service;

Determining, by the first service, a set of resources within a time range from the trigger to the end of the duration of the duration and within the frequency domain.

Correspondingly, the foregoing step 102 may include:

It should be noted that, in this case, when the transmission resource is selected for the data packet of the second service, the transmission resource of the data packet of the second service may be selected from the optional resource set by reducing the degree of selectivity of the resource set. When the terminal evaluates the duration and frequency range of the first service, the terminal may perform evaluation based on various factors, such as the obtained information about the first service related transmission resource and the service characteristic of the first service.

For example, as shown in FIG. 3, in the specific example 2 of the present disclosure, the UE1 participates in the service B (corresponding to the first service), that is, the service, when selecting the transmission resource for the data packet of the service A (corresponding to the second service). The triggering time t3 of B is earlier than the triggering time t4 of the service A, and the service B is a service requiring multiple coordination. There are three vehicle terminals related to the service B, namely UE1, UE2 and UE3. In the second instance, when acquiring the transmission resource related to the service B, the UE1 may obtain all the transmission resources related to the service B, or may not acquire all the transmission resources related to the service B, that is, the transmission resources of the UE1, the UE2, and the UE3 are not acquired. Or only the transmission resources of some UEs in UE1, UE2, and UE3 are acquired.

After acquiring the transmission resource related to the service B, the UE1 may evaluate the duration T′ and the frequency domain range of the service B, and determine the resource set F in the time range and the frequency domain range of the service B from the trigger to the duration of the duration T′. . In this case, referring to FIG. 3, when selecting a transmission resource for the data packet of the service A, the UE1 may select other resources in the resource selection window of the service A except the resources in the time domain corresponding to each resource in the resource set F. The resource sends the packet of service A to avoid the resource set F. When evaluating the duration T′ and the frequency range of the service B, the UE1 may perform evaluation based on the obtained service B related transmission resource condition, service B service characteristic, and the like.

It should be noted that, in the foregoing example 2, when the UE1 selects a transmission resource for the data packet of the service A, the UE1 avoids resources in the time domain corresponding to each resource in the resource set. However, in addition to the avoidance mode, in other examples, the UE1 may also avoid resources on the time-frequency domain corresponding to each resource in the resource set, or avoid the time domain corresponding to a part of resources in the resource set. The resource and the resources in the time-frequency domain corresponding to the other part of the sending resource are the same as the second embodiment, and are not described here. The time-frequency domain corresponding to the resource may be the time-frequency domain corresponding to the resource, or may be the time-frequency domain range corresponding to the resource, and the time-frequency domain range corresponding to the resource may be according to a preset condition of the terminal, a protocol, or UE1 capabilities and the like are determined.

Specifically, in the embodiment of the present disclosure, in the second case, the foregoing step 101 may include:

Obtaining a sending resource related to the first service;

Determining a set of resources related to the first service.

Correspondingly, the foregoing step 102 may include:

The first service-related resource set is the acquired set of the first service-related transmission resource when the first service is a single transmission. When the first service has a retransmission, if all the transmission resources related to the first service are acquired, the first service related resource set is at least one transmission resource of each terminal related to the first service. And the collection of the first service-related resource set is the at least one transmission resource of each terminal of the obtained terminal corresponding to the partial transmission resource, if the collection of the first service-related partial transmission resource is obtained. Collection.

For example, in the third embodiment of the present disclosure, the UE1 participates in the service B (corresponding to the first service) and the service B needs to be multiple times when the transmission resource has been selected for the data packet of the service A (corresponding to the second service). For the coordinated service, there are three vehicle terminals related to service B, namely UE1, UE2 and UE3.

When the service B is a single transmission, all the transmission resources related to the service B include the transmission resource 1 of the UE1, the transmission resource 2 of the UE2, and the transmission resource 3 of the UE3. At this time, if the UE1 obtains all the transmission resources related to the service B, the resource set related to the service B determined by the UE1 is the set of the transmission resources of all the terminals related to the service B, that is, the transmission resource 1 of the UE1, and the transmission resource 2 of the UE2. And a set of transmission resources 3 of UE3. If the UE1 obtains the partial transmission resources related to the service B, for example, the transmission resource 2 of the UE2 and the transmission resource 3 of the UE3, the resource set related to the service B determined by the UE1 is the transmission resource 2 of the UE2 and the transmission resource 3 of the UE3. . In this case, if the time-frequency domain corresponding to the transmission resource selected for the data packet of the service A is TF1, there is overlap between the time domain or the time-frequency domain corresponding to at least one of the transmission resources of the TF1 and the service B-related resource set. Time-frequency domain TF1'. For example, there is overlap between the time domain corresponding to TF1 and the transmission resource 1, overlap between the time-frequency domain corresponding to the TF1 and the transmission resource 3, and overlap between the time domain corresponding to the TF1 and the transmission resource 1 and the transmission resource 2, and TF1. If there is overlap between the time domain corresponding to the transmission resource 1 and the time-frequency domain corresponding to the transmission resource 3, the UE 1 discards all the transmission resources that have been selected for the data packet of the service A, or discards the overlapping frequency domain TF1'. All or part of the sending resource is sent, or the resource reselection of the service A is triggered.

When the service B has retransmissions, taking two retransmissions (but not limited to two, or one or N times, and N is greater than 2), the UE1 first determines the resource set related to the service B, and the UE1 determines the The set of resources related to the service B can be as described in the first embodiment, and details are not described herein again. In this case, if the time-frequency domain corresponding to the transmission resource selected for the data packet of the service A is TF2, there is an overlap between the time domain or the time-frequency domain corresponding to at least one of the resource collections of the TF2 and the service B-related resource set. Time-frequency domain TF2'. For example, there is overlap between TF1 and the time domain corresponding to the first 1 of the transmission resource, and there is overlap between the TF1 and the time-frequency domain corresponding to the transmission resource initial 3 and the transmission resource double 1; TF1 and the transmission resource are heavy 1. The transmission resource is initial 2 And there is overlap between the time domains corresponding to the transmission resource triple 3, the time domain corresponding to the TF1 and the first 1 of the transmission resource, and the time-frequency domain corresponding to the transmission resource double 3, and the UE1 abandons the service A. All the transmission resources selected by the data packet, or all or part of the transmission resources in the overlapping time frequency domain TF2' are discarded, or the resource reselection of the service A is triggered. The time-frequency domain corresponding to the transmission resource may be the time-frequency domain corresponding to the actual transmission resource, or may be the time-frequency domain range corresponding to the transmission resource, and the time-frequency domain range corresponding to the transmission resource may be based on the preset condition of the terminal, The agreement is agreed, or the UE1 capability, etc. is determined.

In this way, a part of the transmission resources in the transmission resource selected for the data packet of the service A is discarded, which can avoid affecting the service B, and can satisfy the requirement of the service A as much as possible, and the transmission resource of the data packet of the service A that has not been abandoned is Any initial retransmission of resources will not be all FDM.

In addition, in the embodiment of the present disclosure, in the second case, the foregoing step 101 may further include:

Obtaining a sending resource related to the first service;

Evaluating the duration of the first service;

Correspondingly, the foregoing step 102 may include:

For example, in the fourth embodiment of the present disclosure, the UE1 participates in the service B (corresponding to the first service) and the service B needs to be multiple times when the transmission resource has been selected for the data packet of the service A (corresponding to the second service). For the coordinated service, there are three vehicle terminals related to service B, namely UE1, UE2 and UE3. In the fourth instance, when acquiring the transmission resource related to the service B, the UE1 may obtain all the transmission resources related to the service B, or may not acquire all the transmission resources related to the service B, that is, the transmission resources of the UE1, the UE2, and the UE3 are not acquired. Or only the transmission resources of some UEs in UE1, UE2, and UE3 are acquired.

After acquiring the transmission resource related to the service B, the UE1 may evaluate the duration T′ and the frequency domain range of the service B, and determine the resource set F in the time range and the frequency domain range of the service B from the trigger to the duration of the duration T′. . In this case, if the time-frequency domain corresponding to the transmission resource selected for the data packet of the service A is TF3, there is an overlapping time-frequency domain TF3 between the time domain or the time-frequency domain corresponding to at least one resource in the TF3 and the resource set F. ', then UE1 discards all the transmission resources that have been selected for the data packet of service A, or discards all or part of the transmission resources in the transmission resources on the overlapping time frequency domain TF3', or triggers resource reselection of service A. When evaluating the duration T′ and the frequency range of the service B, the UE1 may perform evaluation based on the obtained service B related transmission resource condition, service B service characteristic, and the like. The time-frequency domain corresponding to the resource may be the time-frequency domain corresponding to the resource, or may be the time-frequency domain range corresponding to the resource, and the time-frequency domain range corresponding to the resource may be according to a preset condition of the terminal, a protocol, or UE1 capabilities and the like are determined.

In a specific embodiment of the present disclosure, the relationship between the first service and the second service may be described from multiple dimensions, including priority, whether multiple cooperation is required, whether it is an event triggered service, a communication delay requirement, a communication distance requirement, Communication reliability requirements, communication data rate requirements, communication methods (unicast, multicast, broadcast), associated UE attributes (vehicles, roadside infrastructure, pedestrians, motorcycles, vulnerable road users), urgency Wait. For example, according to the priority level and whether the service needs multiple collaborations, the correspondence between the first service and the second service may be as shown in Table 1 below:

The centralized management center selects and transmits resources for all or part of the terminals related to the first service, wherein the centralized management center is, for example, a base station in the network, a roadside unit of the road, a control unit of the transportation department, etc., and is mainly used as a terminal. The business is smoothly carried out to provide services.

Further, when the terminal related to the first service does not select a transmission resource for itself, the terminal related to the first service acquires a transmission resource selected by an entity that selects a transmission resource, and sends the transmission resource on the acquired transmission resource. .
