Description

Resource selection method and terminal

Technical Field

The embodiment of the invention relates to the technical field of computers, in particular to a resource selection method and a terminal.

Background

Device-to-Device (D2D) communication based on cellular networks is also called Proximity Service (ProSe) in The 3rd Generation Partnership Project (3 GPP), and D2D communication allows terminals to directly communicate with each other by multiplexing cell resources, which can increase The spectral efficiency of a cellular communication system and reduce The transmission power of The terminals, and alleviate The problem of poor spectral resources in a wireless communication system to some extent.

The application scenarios of D2D in real life include vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), V2V, V2I, and V2P all belong to the internet of vehicles (V2X), V2X is a key technology of future intelligent transportation system, allowing the vehicle to continuously communicate with all other nearby vehicles and road infrastructures, rather than the vehicle communicating with traffic lights, school districts, and railroad crossings, etc., the vehicle may be an embedded telematics system in the vehicle, or a mobile device such as a smartphone on the vehicle, etc. which undertakes communication tasks. In the V2P service, the V2P application information may be transmitted by in-vehicle UEs supporting the V2X application or UEs related to road users supporting the V2X application.

Traffic flow of a communication terminal in V2X communication is periodic, for example, a minimum period of Cooperative Awareness information (CAM) is 100ms, a maximum period is 1s, the terminal can predict what traffic may be sent next according to the periodicity of the traffic, and a scheme of resource reservation is specially added in V2X so that the terminal reserves communication resources for the predicted traffic. The terminal may inform other terminals that it is to reserve some time-frequency resource in the future. On the other hand, when selecting the time-frequency resource for transmitting data, the terminal considers the resources reserved by other terminals, and avoids selecting the resources already reserved by other terminals as much as possible, that is, the terminal monitors when selecting the time-frequency resource. When the terminal selects the time-frequency resource, a part of the resources reserved by other terminals are excluded, and then one resource is randomly selected from the rest communication resources as the reserved resource. How to select resources in particular is a technical issue that is being studied by the person skilled in the art.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a terminal 10 according to an embodiment of the present invention. The terminal 10 includes a processor 101, a memory 102, and a transceiver 103, and the processor 101, the memory 102, and the transceiver 103 may be connected to each other through a bus. The bus may be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, an extended standard architecture (EISA) bus, or the like.

The transceiver 103 (including a modem) may be connected to an antenna, the transceiver 103 is used for converting electromagnetic waves received by the antenna into electric current and finally into digital signals, and accordingly, the transceiver 103 is also used for converting digital signal data to be output by the terminal 10 into electric current and then into electromagnetic waves, and finally transmitting the electromagnetic waves into free space through the antenna. The transceiver 103 may also include at least one amplifier for amplifying signals. In general, WIreless transmission, such as Bluetooth (Bluetooth) transmission, WIreless-Fidelity (WI-FI) transmission, 3rd-Generation (3G) transmission, 4 th-Generation (4G) transmission, Long Term Evolution (LTE) transmission, 5th-Generation (5G) transmission, etc., may be performed through the transceiver 103.

The Memory 102 includes, but is not limited to, a Random Access Memory (RAM), a Read-Only Memory (ROM), an Erasable Programmable Read-Only Memory (EPROM), or a portable Read-Only Memory (CD-ROM), and may specifically include a storage instruction area for storing instructions required by the processor 101 during operation and a storage data area for storing preconfigured data or data generated by the processor 101 during operation.

The processor 101 is a control center of the terminal 10, connects various parts of the entire terminal 10 using various interfaces and lines, and performs various functions of the terminal 10 by executing programs stored in the memory 102 and calling data stored in the memory 102. Alternatively, if the terminal is an automobile, a distance sensor may be used for backing up and controlling the distance, so the terminal 10 may be provided with the distance sensor 104, and the processor 101 may control the distance sensor 104 to collect distance data by calling a program in the memory 102. Optionally, the processor 101 may include one or more application processors, such as a Central Processing Unit (CPU). In an embodiment of the invention, the processor 101 may perform the method flow shown in FIG. 2 by calling instructions and data in memory.

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

step S201: the terminal determines a target resource from 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, and in general, the terminal needs to select (or "determine") appropriate resources before transmitting data or signals, which may be referred to as determined resources used for transmitting data or signals as target resources. The resource to be selected may be one or multiple resources, and in the embodiment of the present invention, the resource to be selected is collectively referred to as at least one resource, each resource in the at least one resource has a respective attribute, and the attribute of each resource is one of at least one attribute, and the number of the at least one attribute may be preset, for example, the at least one attribute is 2 attributes, where the 2 attributes are specifically attribute 1 and attribute 2, the at least one resource is 30 resources, and the attribute of 10 resources in the 30 resources is attribute 1, and the attribute of the other 20 resources is attribute 2. What attribute each resource in the at least one resource is may be predefined or categorized in real-time by a predetermined algorithm. Optionally, the at least one attribute at least includes an overlapping attribute, optionally, the at least one attribute at least includes a non-overlapping attribute, optionally, the at least one attribute at least includes an overlapping attribute and a non-overlapping attribute, and there may be other names for the overlapping attribute and the non-overlapping attribute, for example, the overlapping attribute may also be referred to as a "shared" attribute, and the non-overlapping attribute may also be referred to as a "non-shared" attribute.

Optionally, the resource with the overlapping attribute is a resource that can be used by multiple services planned in advance, and the resource with the non-overlapping attribute is a resource that can be used by one of the multiple services (i.e., only one service has a selection right for the resource with the attribute), for example, the multiple services include P2X-related V2X sidelink communication and non-P2X-related V2X sidelink communication.

Optionally, the resource with the overlapping attribute is a resource that can be used by any of a plurality of resource selection manners, and the resource with the non-overlapping attribute is a resource that can be used by one of the plurality of resource selection manners, for example, the plurality of resource selection manners include a resource selection manner based on monitoring and a resource selection manner based on random selection.

There are many possibilities for implementing step S201, and two alternatives are selectively listed below, where the first alternative is steps S2011-S2012, and the second alternative is step S2016, specifically as follows:

the first alternative is:

step S2011: the terminal determines one attribute among the at least one attribute.

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

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

Scheme A: the terminal determines a target attribute from at least one attribute, which may specifically be: the terminal determines a target attribute in the at least one attribute according to the probability corresponding to each attribute in the at least one attribute, for example, a numerical value is generated according to a preset rule; and determining one attribute in the at least one attribute according to the relationship between the numerical value and the probability corresponding to each attribute in the at least one attribute, wherein the determined attribute is the target attribute. Optionally, each attribute in the at least one attribute corresponds to a probability, and a sum of the probabilities corresponding to the attributes is equal to 1.

It should be noted that, the probability corresponding to each attribute in 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 in the at least one attribute is pre-configured in the terminal, for example, the memory of the terminal stores the probability corresponding to each attribute in advance, and for example, the probability corresponding to each attribute is carried in a card (for example, a Subscriber Identity Module (SIM) card, a memory card) or a chip or a magnetic stripe inserted into the terminal by a user. Or the probability corresponding to each attribute in the at least one attribute is determined according to at least one of the occupancy rate CBR, the congestion degree, and the utilization rate of the resource of the at least one attribute, for example, assuming that the at least one attribute includes an overlapping attribute and a non-overlapping attribute, the UE measures the CBR of the overlapping attribute resource and the CBR of the non-overlapping attribute resource, respectively, and the greater the ratio of the CBR of the non-overlapping attribute resource to the CBR of the overlapping attribute resource, the lower the probability of determining the non-overlapping attribute is, 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.

Scheme B: the terminal determines the target attribute in the at least one attribute, which may specifically be: and selecting one attribute from the at least one attribute according to at least one of CBR, congestion degree and utilization rate of the resource of each attribute, wherein the selected attribute is the target attribute. For example, the terminal obtains (e.g., measures) the CBR of each resource of the overlapping attribute, then calculates an average CBR of the resources of the overlapping attribute according to the CBR of each resource of the overlapping attribute, and determines the non-overlapping attribute if the CBR of the resources of the overlapping attribute is higher than or equal to a preset threshold. For another example, the terminal obtains (e.g., measures) the CBR of each resource with the non-overlapping attribute, then calculates an average CBR of the resource with the non-overlapping attribute according to the CBR of each resource with the non-overlapping attribute, and determines the non-overlapping attribute if the average CBR of the resource with the non-overlapping attribute is lower than or equal to a preset threshold.

Step S2012: the terminal determines a target resource with the attribute as the target attribute in at least one resource.

Specifically, resources with various attributes may exist in the at least one resource, where the resources include a resource with a target attribute, in the embodiment of the present invention, the terminal may select a resource with an attribute as the target attribute from the at least one resource, and the number of the selected resources may be one or multiple; the selection can be random or according to a predefined rule.

In the first alternative, the terminal selects the target attribute before selecting the resource, and then selects the required resource from the resources belonging to the target attribute, which has the advantage that the policy can be configured to make the probability that the target attribute selected by the terminal is the non-overlapping attribute higher, so that the terminal can select the resource with the non-overlapping attribute more easily, and the resource selected by the terminal can be prevented from being the same as the resource used by other devices as much as possible, thereby reducing the conflict of resource use.

A second alternative:

step S2016: the terminal determines a target resource according to an attribute and a received signal strength of each resource in at least one resource, where the received signal strength of each resource is the received signal strength received by the terminal on the resource, that is, at least two pieces of information, namely, the attribute and the received signal strength of the resource, need to be considered when determining the target resource, but the two pieces of information are not limited here specifically, and two implementation manners are listed below to facilitate understanding.

The implementation mode is as follows: the terminal determines the target resource according to the attribute and the received signal strength of each resource in the at least one resource, which may specifically be:

firstly, the terminal sorts at least one resource according to the attribute of each resource in the at least one resource, and the resources with the same attribute are sorted according to the signal receiving intensity of each resource, namely, the sorting at least needs to consider two factors of the attribute of the resource and the signal receiving intensity of the resource, and the priority of the attribute is higher than the priority of the signal receiving intensity; for example, the at least one resource shares resources of two attributes, i.e., the resource with higher received signal strength in the first type of resource is ranked earlier, and the resource with higher received signal strength in the second type of resource is ranked earlier; 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 selects the resource from the sorting result as the target resource, or selects the resource from the 1 st to the T th resources from the last in the sorted list as the target resource, or selects the resource from the 1 st to the T th resources from the order in the sorted list as the target resource, where T is greater than or equal to 1. The selection may be performed according to a predetermined algorithm, such as a random algorithm.

The implementation mode two is as follows:

the terminal determines the target resource according to the attribute and the received signal strength of each resource in the at least one resource, which may specifically be: the terminal determines a target resource according to the received signal strength of each resource in at least one resource and the weight factor corresponding to the attribute of each resource. Each attribute in the at least one attribute corresponds to a respective weighting factor, and the weighting factors corresponding to two different attributes are generally not equal (although the possibility of equality is not excluded), for example, the at least one attribute refers to an overlapping attribute and a non-overlapping attribute, where the weighting factor corresponding to the overlapping attribute is 0.3, and the weighting factor corresponding to the non-overlapping attribute is 0.7, and the weighting factor corresponding to the attribute of the resource and the received signal strength of the resource need to be considered when determining that the target resource is the resource.

It should be noted that, the weighting factor corresponding to each attribute in 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 weighting factor corresponding to each attribute. Or the weighting factor corresponding to each attribute in the at least one attribute is configured in advance, for example, the weighting factor corresponding to each attribute is stored in advance in the memory of the terminal, and for example, the weighting factor corresponding to each attribute is carried in a card (e.g., a Subscriber Identity Module (SIM) card, a memory card) or a chip or a magnetic stripe inserted into the terminal by a user. Or the weighting factor corresponding to each attribute of the at least one attribute is determined according to at least one of the occupancy rate CBR, the congestion degree and the utilization rate of the resource of each attribute, for example, assuming that the at least one attribute includes an overlapping attribute and a non-overlapping attribute, the UE measures the CBR of each resource of the overlapping attribute and the CBR of each resource of the non-overlapping attribute respectively, then calculating the average CBR of the resources with the overlapping attributes according to the CBR of each resource with the overlapping attributes, and calculating an average CBR of the resources of the non-overlapping attributes from the CBRs of the respective resources of the non-overlapping attributes, the greater the ratio of the average CBR of the resources of the non-overlapping attributes to the average CBR of the resources of the overlapping attributes, the lower the weighting factor for determining non-overlapping attributes, in summary, the weighting factor for each attribute can be calculated according to the CBR of the resource, but the details of the calculation 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 weight factor corresponding to the attribute of each resource, which may specifically be:

firstly, 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 a non-overlapping attribute, 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 resource 1 belongs to the resource with overlapping attribute and the received signal strength is 50, resource 2 belongs to the resource with overlapping attribute and the received signal strength is 200, resource 3 belongs to the resource with overlapping attribute and the received signal strength is 400, resource 4 belongs to the resource with non-overlapping attribute and the received signal strength is 50, resource 5 belongs to the resource with non-overlapping attribute and the received signal strength is 200, resource 6 belongs to the resource with non-overlapping attribute and the received signal strength is 400, then, one can get the metric value for resource 1 equal to 50 x 0.3-15, the metric value for resource 2 equal to 200 x 0.3-60, the metric value for resource 3 equal to 400 x 0.3-120, the metric value for resource 4 equal to 50 x 0.7-35, the metric value for resource 5 equal to 200 x 0.7-140, and the metric value for resource 6 equal to 400 x 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 sorting principle may be that the smaller the metric value corresponding to the resource, the closer the resource is sorted, and if the sorting is performed by taking the metric values of the above 6 resources as an example, the sorting is performed from front to back in sequence: resource 1, resource 4, resource 2, resource 3, resource 5, resource 6.

Finally, the terminal determines the target resource according to the sorting result of the at least one resource, for example, directly selects the resource from the sorting result as the target resource, or selects the resource from the 1 st to the T th resource from the sorted list as the target resource, or selects the resource from the 1 st to the T th resource from the order number from the sorted list as the target resource, and T is greater than or equal to 1. The selection may be performed according to a predetermined algorithm, such as a random algorithm.

In the second implementation manner, when the terminal ranks the at least one resource, the terminal does not directly rank the at least one resource according to the received signal strength of the at least one resource, but calculates the metric value of each resource according to the weight factor corresponding to the attribute of each resource, ranks the at least one resource according to the metric value of each resource in the at least one resource, and finally selects the required resource from the ranking result; this has the advantage that the terminal can be made easier to select the desired resource by configuring the weighting factors for the various attributes.

Step S202: the terminal transmits data or signals through the target resource.

Specifically, the terminal may transmit data or signals using the target resource immediately after determining the target resource; of course, the target resource may also be a resource determined by the terminal for transmitting data or signals at a future time or a resource reserved for some kind of subsequent information, and when the time for using the target resource is reached, the terminal transmits the data or signals through the target resource.

The above steps S201-S202 describe the process of selecting resources by the terminal, and there may be indication information for triggering the process, where the indication information includes at least the following two cases: in a first case, the indication information may be configured in the terminal in advance (for example, stored in a memory, a chip, a card, or the like of the terminal), and the terminal may read the indication information to determine whether the process needs to be executed, execute the process if the process needs to be executed, and not execute the process if the process does not need to be executed; in the second case, the network side device sends the indication information (there may be other calls, such as a trigger message) to the terminal, and accordingly, the terminal receives the indication information and determines whether the flow needs to be executed according to the indication information, if so, the flow is executed, and if not, the flow is not executed. The specific function or content of the indication information has at least the following possibilities.

The first possibility is that the indication information directly indicates whether the terminal needs to execute the above-mentioned process.

The second possibility is that the indication information indicates a resource attribute, and the terminal determines whether to execute the above process according to the resource attribute. For example, the indication information indicates that the resource is a resource with an overlapping attribute, or the indication information indicates that the resource can be used by the terminal and the 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 and the other information indicates that the resource can also be used by the terminal, so that the terminal can determine (possibly use the other information) that the resource is a resource with an overlapping attribute according to the indication information. When the resource is the resource with the overlapped attribute, the terminal triggers the process, and when the resource is the resource with the non-overlapped attribute, the terminal does not trigger the process.

And a third possibility that the indication information indicates at least one of the CBR, the congestion degree, and the utilization rate of the resource, and the terminal determines whether to execute the above process according to the content indicated by the indication information, for example, when the CBR of the resource (or the congestion degree of the resource, or the resource utilization rate) is higher than or equal to a certain preset threshold, the terminal triggers to execute the above process.

In the method shown in fig. 2, when the terminal selects the target resource from at least one resource sequence, the target resource is selected according to the attribute divided for each resource in advance, and the attribute can be specially configured in advance according to needs, so that the terminal can select the resource to be selected from the at least one resource more easily.
