Description

Resource selection method and terminal Technical field

The present invention relates to the field of computer technologies, and in particular, to a resource selection method and a terminal.

Background technique

Device-to-Device (D2D) communication based on cellular network is also called Proximity Service (ProSe) in the 3rd Generation Partnership Project (3GPP), and D2D communication allows terminal By directly communicating by multiplexing cell resources, the spectrum efficiency of the cellular communication system can be increased and the terminal transmission power can be reduced, which alleviates the problem of lack of spectrum resources in the wireless communication system to some extent.

D2D real-life applications include vehicle to vehicle (V2V) and vehicle to infrastructure (V2I), vehicle to pedestrian (V2P), V2V, V2I and V2P. Vehicle to everything (V2X), V2X is the key technology for future intelligent transportation systems, allowing cars to communicate continuously with all other nearby vehicles and road infrastructure, than between cars such as traffic lights, campuses and railroad crossings. Communication, which can undertake communication tasks in a car, may be an embedded telematics system in a car, or a mobile device such as a smartphone on a car, and the like. In a V2P service, an in-vehicle UE supporting a V2X application or a UE related to a road user supporting a V2X application can transmit V2P application information.

The service traffic of the communication terminal in the V2X communication is cyclical. For example, the shortest period of the Cooperative Awareness Message (CAM) is 100 ms, and the longest period is 1 s. The terminal can predict the next possible according to the periodicity of the traffic. What traffic is to be sent, the V2X specifically adds a resource reservation scheme for the terminal to reserve communication resources for the predicted traffic. The terminal can inform other terminals that it wants to reserve some time-frequency resources in the future. On the other hand, when selecting the time-frequency resource for transmitting data, the terminal should consider the resources reserved by other terminals, and try to avoid selecting resources that other terminals have reserved, that is, the terminal should monitor when selecting time-frequency resources. When selecting the time-frequency resource, the terminal excludes some resources that have been reserved by other terminals, and then randomly selects one resource as the reserved resource among the remaining communication resources. How to select resources in detail is a technical problem that those skilled in the art are studying.

Optionally, the processor 101 may include one or more application processors, for example, a central processing unit (CPU).

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a resource selection method according to an embodiment of the present invention. Optionally, the method may be implemented based on the terminal shown in FIG. 1, and the method includes but is not limited to the following steps:

Step S201: The terminal determines the target resource from the at least one resource according to the attribute of the resource.

Specifically, the terminal needs to use resources (also referred to as “time-frequency resources”) when transmitting data or signals. Generally, the terminal needs to select (or “determine”) the appropriate resources before transmitting the data or signals, which may be called determining. The resource used to transmit data or signals is the target resource. The resource to be selected may be one or more. The embodiment of the present invention is generally referred to as a candidate resource as at least one resource, and each resource of the at least one resource has a respective attribute and the attribute of each resource is at least one. One of the attributes, the quantity of the at least one attribute may be preset, for example, the at least one attribute is two attributes, and the two attributes are specifically attribute 1 and attribute 2, and the at least one resource is 30 assets Source, the attribute of 10 of the 30 resources is attribute 1 and the attribute of the other 20 resources is attribute 2. Each of the at least one resource may be pre-defined or may be categorized in real time by a predetermined algorithm. Optionally, the at least one attribute includes at least an overlapping attribute. Optionally, the at least one attribute includes at least a non-overlapping attribute. Optionally, the at least one attribute includes at least an overlapping attribute and a non-overlapping attribute, and the overlapping attribute and Non-overlapping attributes may also have other names. For example, overlapping attributes may also be referred to as "shared" attributes, and non-overlapping attributes may also be referred to as "non-shared" attributes.

Optionally, the resource of the overlapping attribute is a resource that can be used by multiple pre-planned resources, and the resource of the non-overlapping attribute is a resource that can be used by one of the multiple services (that is, only one type of service is used for the The resources of the attribute have selection rights. For example, the plurality of services include P2X-related V2X side-link communication and non-P2X-related V2X side-link communication.

Optionally, the resource of the overlapping attribute is a resource that can be used in multiple resource selection manners, and the resource of the non-overlapping attribute is a resource that can be used in one of the multiple resource selection modes, for example, the multiple Resource selection methods include monitoring based resource selection methods and resource selection methods based on random selection.

There are many possibilities in the specific implementation of the step S201. The following two alternatives are described in the following. The first alternative is the step S2011-S2012, and the second alternative is the step S2016, as follows:

The first option is:

Step S2011: The terminal determines an attribute in at least one attribute.

Specifically, the embodiment of the present invention uses a certain rule to determine an attribute from the preset at least one attribute as a target attribute, so as to subsequently select resources from the resources belonging to the target attribute (each resource has its own attribute and the resource The attribute is one of the at least one attribute, and the attributes of the two different resources may be the same or different.

The certain rules may be pre-configured as needed, and several alternatives are schematically illustrated below.

The solution A: determining, by the terminal, the target attribute in the at least one attribute, where the terminal determines the target attribute in the at least one attribute according to the probability corresponding to each attribute of the at least one attribute, for example, according to the preset The rule generates a value; and determining an attribute in the at least one attribute according to the magnitude relationship of the value and the probability corresponding to each of the at least one attribute obtained in advance, and the determined attribute is the target attribute. Optionally, each attribute of the at least one attribute corresponds to a probability, and a sum of probabilities corresponding to each attribute is equal to 1.

It should be noted that the probability corresponding to each attribute of the at least one attribute is configured by the network side device. For example, the base station sends a message to the terminal, where the message carries the probability corresponding to each attribute. Or the probability corresponding to each attribute of the at least one attribute is pre-configured in the terminal, for example, the probability of each attribute corresponding to each attribute is pre-stored in the memory of the terminal, and, for example, the card inserted by the user into the terminal (For example, a Subscriber Identification Module (SIM) card, a memory card) or a chip or a magnetic strip carries the probability that each attribute corresponds to each. Or the probability that each attribute of the at least one attribute corresponds to is determined according to at least one of a channel occupancy rate CBR, a congestion level, and a utilization rate of the resource of each attribute, for example, the at least one attribute is included The overlapping attribute and the non-overlapping attribute, the UE separately measures the CBR of the overlapping attribute resource and the CBR of the non-overlapping attribute resource, and the larger the ratio of the CBR of the resource of the non-overlapping attribute to the CBR of the resource of the overlapping attribute, the more the probability of determining the non-overlapping attribute is Low, in short, the probability of each attribute can be calculated according to the CBR of the resource, but the specific calculation details are not limited here. Congestion level, resource utilization

Solution B: The terminal determines the target attribute in the at least one attribute, which may be specifically: according to the at least one attribute At least one of the CBR, the degree of congestion, and the utilization of the resource of each attribute selects one attribute from the at least one attribute, and the selected attribute is the target attribute. For example, the terminal acquires (eg, measures) the CBR of each resource of the overlapping attribute, and then calculates the average CBR of the resource of the overlapping attribute according to the CBR of each resource of the overlapping attribute, if the CBR of the resource of the overlapping attribute is higher than or equal to a certain A preset threshold determines a non-overlapping attribute. For another example, the terminal acquires (eg, measures) the CBR of each resource of the non-overlapping attribute, and then calculates the average CBR of the resource of the non-overlapping attribute according to the CBR of each resource of the non-overlapping attribute, if the average CBR of the resource of the non-overlapping attribute is lower than or Equal to a preset threshold to determine non-overlapping attributes.

Step S2012: The terminal determines, in at least one resource, a target resource whose attribute is the target attribute.

Specifically, in the at least one resource, there are resources of various attributes, including resources of the target attribute. In the embodiment of the present invention, the terminal selects a resource whose attribute is the target attribute from the at least one resource, and the quantity of the selected resource. It can be one or more; it can be selected randomly when it is selected, or it can be selected according to a predefined rule.

In the first optional solution, the terminal selects the target attribute before selecting the resource, and then selects the required resource from the resources belonging to the target attribute. The advantage of this is that the policy can be configured to make the terminal select the selected one. The probability that the target attribute is a non-overlapping attribute is larger, so that the terminal can more easily select the resource of the non-overlapping attribute, and can avoid the resource selected by the terminal to be the same as the resource used by other devices, thereby reducing the conflict of resource usage.

The second option is:

Step S2016: The terminal determines a target resource according to an attribute of each resource in at least one resource and a received signal strength, where a received signal strength of each resource is a received signal strength received by the terminal on the resource, that is, When determining the target resource, at least two kinds of information, such as the attribute of the resource and the strength of the received signal, need to be considered. However, the specific information of the two kinds of information is not limited herein. Two implementation modes are listed below to facilitate understanding.

Implementation manner 1: The terminal determines the target resource according to the attribute of each resource in at least one resource and the received signal strength, which may be specifically:

First, the terminal sorts the at least one resource according to the attribute of each resource in the at least one resource, and each resource of the same attribute is sorted according to the size of the signal receiving strength of the each resource, that is, the sorting needs at least the resource consideration Two factors of the received signal strength of the attribute and the resource, the priority of the attribute is higher than the priority of the received signal strength; for example, the resources of the first type and the second type are shared among the at least one resource, all first The resources of the class are ranked before all the resources of the second class. The resource with the stronger received signal strength in each class of resources is ranked higher. That is, in the first class of resources, the resource with higher received signal strength is ranked higher. In the second type of resources, the resource with the higher received signal strength is ranked higher; optionally, the first type is a non-overlapping attribute, and the second type is an overlapping attribute.

Then, the terminal determines the target resource according to the sorting result of the at least one resource, for example, directly selecting the resource as the target resource from the sorted result, or selecting from the first to the last Tth resources from the sorted list The resource is used as the target resource, or the resource is selected as the target resource from the first to the right T-th resource in the sorted list, and T is greater than or equal to 1. When selecting, it can be selected according to a preset algorithm, such as a random algorithm.

Implementation 2:

The terminal determines the target resource according to the attribute of each resource and the received signal strength of the at least one resource, and may be specifically: the terminal determines, according to the received signal strength of each resource in the at least one resource, and the weighting factor corresponding to the attribute of each resource. Target resources. Each of the at least one attribute corresponds to a respective weighting factor, two different attributes The corresponding weighting factors are generally not equal (but do not exclude equal possibilities). For example, the at least one attribute refers to an overlapping attribute and a non-overlapping attribute, wherein the overlapping attribute corresponds to a weighting factor of 0.3, and the non-overlapping attribute corresponds to a weight. The factor is 0.7, and the weighting factor corresponding to the attribute of the resource and the received signal strength of the resource are determined in determining the target resource.

It should be noted that the weighting factor corresponding to each attribute of the at least one attribute is configured by the network side device. For example, the base station sends a message to the terminal, where the message carries a weighting factor corresponding to each attribute. Or the weighting factor corresponding to each attribute of the at least one attribute is pre-configured, for example, the weighting factor corresponding to each attribute is pre-stored in the memory of the terminal, and, for example, the card inserted by the user into the terminal (for example, A Subscriber Identification Module (SIM) card, a memory card, or a chip or a magnetic strip carries a weighting factor corresponding to each attribute. Or the weighting factor corresponding to each attribute of the at least one attribute is determined according to at least one of a channel occupancy rate CBR, a congestion level, and a utilization rate of the resource of each attribute, for example, if the at least one attribute is included The overlapping attribute and the non-overlapping attribute, the UE respectively measures the CBR of each resource of the overlapping attribute and the CBR of each resource of the non-overlapping attribute, and then calculates the average CBR of the resource of the overlapping attribute according to the CBR of each resource of the overlapping attribute, and according to the non-overlapping The CBR of each resource of the attribute calculates the average CBR of the resource of the non-overlapping attribute, and the larger the ratio of the average CBR of the resource of the non-overlapping attribute to the average CBR of the resource of the overlapping attribute, the lower the weighting factor of the non-overlapping attribute is determined, in general, The weighting factor of each attribute can be calculated according to the CBR of the resource, but the specific calculation details are not limited herein.

Optionally, the terminal determines the target resource according to the received signal strength of each resource in the at least one resource and the weighting factor corresponding to the attribute of each resource, which may be specifically:

First, the terminal multiplies the received signal strength of each resource in the at least one resource by a weight factor corresponding to the attribute of each resource to obtain a metric value of each resource; for example, the at least one attribute includes an overlapping attribute. And non-overlapping attributes, wherein the overlapping attribute corresponds to a weighting factor of 0.3, and the non-overlapping attribute corresponds to a weighting factor of 0.7; assuming that the at least one resource refers to resource 1, resource 2, resource 3, resource 4, resource 5, and resource 6, wherein the resource 1 belongs to the resource of the overlapping attribute and the received signal strength is 50, the resource 2 belongs to the resource of the overlapping attribute, and the received signal strength is 200, the resource 3 belongs to the overlapping attribute, and the received signal strength is 400, and the resource 4 belongs to the non- If the resource with overlapping attributes and the received signal strength is 50, the resource 5 belongs to the non-overlapping attribute, and the received signal strength is 200, the resource 6 belongs to the non-overlapping attribute, and the received signal strength is 400, then the metric of the resource 1 can be obtained. Equal to 50*0.3=15, the metric of resource 2 is equal to 200*0.3=60, the metric of resource 3 is equal to 400*0.3=120, and the metric of resource 4 is equal to 50. *0.7=35, the metric of resource 5 is equal to 200*0.7=140, and the metric of resource 6 is equal to 400*0.7=280.

Then, the terminal sorts the at least one resource according to the metric value of each resource in the at least one resource; for example, the principle of sorting may be that the metric value corresponding to the resource is smaller, and the resource ranking is higher, with the above six resources. If the metric value is sorted by example, the order from the going to the back is: resource 1, resource 4, resource 2, resource 3, resource 5, and resource 6.

Finally, the terminal determines the target resource according to the sorting result of the at least one resource, for example, directly selecting the resource as the target resource from the sorted result, or selecting the resource from the first to the last Tth resource species in the sorted list. As the target resource, or from the ordered list from the first to the t-th resource, the resource is selected as the target resource, and T is greater than or equal to 1. When selecting, it can be selected according to a preset algorithm, such as a random algorithm.

In the implementation manner 2, when the terminal sorts the at least one resource, the metric value of each resource is not directly calculated according to the received signal strength of the at least one resource, but the metric value of each resource is calculated according to the weighting factor corresponding to the attribute of each resource. And then sorting the at least one resource according to the metric value of each resource in the at least one resource, and finally selecting the required resource from the sorting result; the advantage of doing so is that the terminal can be configured by using a weighting factor of various attributes. It's easier to choose the resources you want to choose.

Step S202: The terminal sends data or a signal through the target resource.

Specifically, the terminal may use the target resource to send data or a signal immediately after determining the target resource; of course, the target resource may also be a resource that is determined by the terminal to send data or signals at a certain moment in the future or for a certain type of information. The reserved resource, when the time of using the target resource is reached, the terminal sends data or signals through the target resource.

The foregoing steps S201-S202 describe the process of selecting a resource by the terminal, and there may be indication information for triggering the process. The indication information has at least the following two situations: In case one, the indication information may be pre-configured in the terminal (for example, The terminal stores the memory, the chip, the card, and the like, and the terminal can read the indication information to determine whether the process needs to be performed. If it is determined that the process needs to be performed, the process is executed, and if it is determined that the foregoing process is not required to be performed, The process does not perform the above process. In the second case, the network side device sends the indication information to the terminal (other indications may also exist, for example, a trigger message). Accordingly, the terminal receives the indication information and determines whether it is needed according to the indication information. The above process is executed, and if it is determined that the above process needs to be executed, the above process is executed, and if it is determined that the above process is not required, the above process is not executed. At least the following possibilities exist for the specific role or content of the indication information.

Possibility one, the indication information directly indicates whether the terminal needs to perform the above process.

Possibility 2, the indication information indicates a resource attribute, and the terminal determines, according to the resource attribute, whether to execute the foregoing process. For example, the indication information indicates that the resource is a resource of an overlapping attribute, or the indication information indicates that the resource can be used by the terminal while other information indicates that the resource can also be used by other devices, or the indication information indicates that the resource can be used by other devices while other information indicates resources. It can also be used by the terminal, so that the terminal can determine (and possibly other information) according to the indication information that the resource is a resource of overlapping attributes. When the resource is a resource with overlapping attributes, the terminal triggers the foregoing process. When the resource is a resource with non-overlapping attributes, the terminal does not trigger the foregoing process.

Possibility 3, the indication information indicates at least one of CBR, congestion degree, and utilization of the resource, and the terminal determines whether to perform the foregoing process according to the content indicated by the indication information, for example, when the CBR of the resource (or the degree of congestion of the resource, or When the resource utilization rate is higher than or equal to a certain threshold, the terminal triggers the above process.
