Description

Resource allocation method, terminal equipment and network equipment

This application requires the priority of the Chinese patent application filed on December 07, 2018 in the Chinese Patent Office, with the application number 201811495806.7 and the application name as "a resource allocation method, terminal equipment and network equipment", the entire content of which is cited by reference Incorporated in this application.

Technical field

This application relates to the field of communications, and in particular, to a resource allocation method, terminal equipment, and network equipment.

Background technique

Vehicle to any object (V2X), that is, the Internet of Vehicles technology, is used as a device in the standardization specification Rel-14/15/16 version of the 3rd generation partnership project (3GPP) A major application of device (device to device, D2D) technology was successfully established. In the V2X scenario, V2X services can be provided through the PC5 interface and the Uu interface. The PC5 interface is an interface defined on the basis of a straight link (sidelink). Using the PC5 interface, communication and transmission can be performed directly between terminal devices. In the V2X pass-through link mode, the resource allocation mode can be divided into a base station scheduling mode (Mode 3) and a terminal device autonomous selection mode (Mode 4). In the terminal device autonomous selection mode, collisions easily occur between different terminal devices, that is, different terminal devices may select the same frequency domain resource to send service data. And the frequency domain resource where the collision occurs carries the service data of different terminal devices, and the different service data affect each other, thereby affecting the delay and reliability of the data transmission on the frequency domain resource. Among them, business data can be divided according to priority. Different priorities have different requirements on the network. Among them, high-priority business data has higher requirements on the delay and reliability of data transmission. Such collisions should be avoided. The situation happened.

In the prior art, in order to avoid the occurrence of a collision, when the terminal device autonomously selects a resource (Mode 4), it first uses a sensing (sensing) method to determine 20% of the idle resources of the system, and then the terminal device is in the 20% of the idle resources. Randomly select frequency domain resources to send business data. Specifically, the terminal device compares the current signal energy of the detected channel with the set threshold value and the energy threshold corresponding to the current service of the channel, and judges that if the terminal device detects that the signal energy on a certain channel is less than the corresponding current service of the channel When the energy threshold is less than the threshold, the channel is determined to be an idle resource.

When low-priority services in the system occupy a lot of resources, and the corresponding energy thresholds of the corresponding resources are also high, when the terminal device determines 20% of idle resources, it is necessary to continuously increase the detection threshold, so that some low priority Channel resources occupied by the higher-level services are identified as idle resources. If these channel resources are used later to send data of high-priority services, the low-priority services and high-priority services collide on the channel, reducing the signal-to-noise ratio of the data of the high-priority services, and the receiver needs to process the channel at the same time. The data of the high-level services and the data of the low-level services increase the delay of the high-priority services and reduce the reliability of the high-priority services.

Summary of the invention

The embodiments of the present application disclose a resource allocation method, which is applied to the automotive field such as V2X or advanced driving assistance system (ADAS), and can be applied to the Internet of Vehicles, such as V2X, LTE-V, etc. This method is used When the data of the first service is sent, the probability of collision with the data of other services when the data of the first service is sent is reduced.

In view of this, the first aspect of the embodiments of the present application provides a resource allocation method, which may include:

In the V2X scenario, when the terminal device sends data of the first service, the terminal device first determines the priority of the first service and obtains resource configuration information. Among them, the correspondence between different services and priorities can be preset in the terminal device at the time of shipment, or later set by manual or high-level application layer settings or other devices. The first service may be a high priority service or a low priority service. The resource configuration information includes a correspondence between at least one priority level and a use probability of at least two frequency domain resources, and the at least one priority level includes the priority of the first service. After determining the priority of the first service, the terminal device may determine the usage probability of the first service in each of the at least two frequency domain resources according to the priority of the first service and the resource configuration information. Therefore, the terminal device may determine the first frequency domain resource from the at least two frequency domain resources according to the usage probability. Finally, the terminal device sends the data of the first service through the first frequency domain resource. An embodiment of the present application provides a resource allocation method. When transmitting data of a first service, a terminal device determines the use probability of the first service on at least two frequency domain resources according to the priority of the first service Then, the first frequency domain resource is determined according to the use probability, and finally the terminal device uses the first frequency domain resource to send data of the first service. Different services can set different probabilities of use according to their different priorities, thus avoiding the chance of collision with each other.

In a possible design, the resource configuration information includes a first usage probability of the at least two frequency domain resources corresponding to a first priority and a second usage probability of the at least two frequency domain resources corresponding to a second priority , The first law is different from the second law, the first law is a law that the first usage probability changes with the increase of the at least two frequency domain resource numbers, and the second law is that the second usage probability varies with the at least two The law of sequence number changes as the frequency domain resources increase. In the embodiment of the present application, the resource configuration information is further described: the resource configuration information can be flexibly configured, and different priorities correspond to different laws of the at least two frequency domain resources, which increases the diversity of the solutions.

In a possible design, among the at least two frequency domain resources, services with different priorities on the same frequency domain resource have different usage probabilities. In the embodiment of the present application, the resource configuration information is further described: in the resource configuration information, at least two frequency domain resources have different usage probabilities corresponding to services of different priorities on the same frequency domain resource, and the usage probability can be set Set at 0%-100%, increasing the diversity of the program.

In a possible design, the method may include: the terminal device determining at least two available frequency domain resources whose signal strength is less than a preset threshold, where the preset threshold is a threshold value determined by channel detection to be channel idle; the terminal The device determining the first frequency domain resource according to the use probability of the first service in at least two frequency domain resources includes: the terminal device according to the at least two available frequency domain resources and the first service in the at least two frequency domain resources The probability of use determines the first frequency domain resource. In the embodiment of the present application, by setting a preset threshold, at least two available frequency domain resources with low signal strength are selected, and then the first frequency domain resource is selected from the at least two available frequency domain resources. A frequency domain resource whose signal strength is less than a preset threshold may be regarded as an available frequency domain resource that is “idle”. The preset threshold may be specified in advance through a protocol and stored in the terminal device, or may be sent by the base station in advance to instruct the terminal device to configure. The preset threshold is a threshold for channel detection to determine that the channel is idle value. Signal strength refers to the strength of the signal currently carried on the frequency domain resource. The lower the signal strength, the more the frequency domain resource is "idle" and the better the quality; the higher the signal strength, the frequency domain resource can be considered "occupied" The more the quality is poorer, the better the quality is, the less interference is encountered when sending and receiving data on frequency domain resources, and the delay and reliability are also better. Therefore, by filtering out the first frequency domain resource from the at least two available frequency domain resources, it is beneficial to further improve the reliability of the data for sending the first service.

In the embodiments of the present application, a method for generating resource resource configuration information is provided, which increases the diversity of solutions.

In a possible design, the terminal device acquiring resource configuration information includes: the terminal device receiving a configuration instruction; and the terminal device generating the resource configuration information according to the configuration instruction. The configuration instruction may be a distribution value of the use probability corresponding to each frequency domain resource of each priority level. The configuration instruction may also be a parameter in a mathematical expression of the probability distribution of the use of each priority on different frequency domain resources. As the convention, the mathematical expression is a linear function, and the use of frequency domain resources corresponding to each priority The probability is linearly distributed as the frequency domain resource number increases. The mathematical expression is y=kx+b, y refers to the use probability, x refers to the frequency domain resource number, and k and b are the parameters of the expression. At this time, the configuration command only needs to transmit k and b therein. In the embodiment of the present application, another method for generating resource resource configuration information is provided, which increases the diversity of solutions.

In a possible design, the method may include: the terminal device determines resource usage information, the resource usage information includes statistical information of data with different priorities sent through the at least two frequency domain resources; the terminal device uses the resource The information adjusts the resource configuration information.

detailed description

The resource allocation method and network device provided in the embodiments of the present application will be described in detail below with reference to the drawings.

Mobile communication technology has profoundly changed people's lives, but people's pursuit of higher performance mobile communication technology has never stopped. In order to cope with the explosive growth of mobile data traffic in the future, the connection of massive mobile communication devices, and various emerging new services and application scenarios, the fifth generation mobile communication system (the 5th generation) (5G) came into being. The International Telecommunication Union (ITU) has defined three major application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), high reliability and low latency communication (ultrareliable and low latency) communications, URLLC) and massive machine type communications (mMTC).

D2D technology refers to the technology of directly transmitting data between neighboring devices in a communication network. In the 5G system, the terminal equipment of each node of the D2D communication network has higher requirements. The terminal equipment of each user node can send and receive signals, and has the function of automatic routing (forwarding of messages). Once the D2D communication link is established, data can be directly transmitted between different nodes without passing through intermediate entities, which can reduce the pressure on the core network of the communication system, greatly improve spectrum utilization and throughput, and expand network capacity.

V2N refers to the communication between LTE-based vehicles and base station/network. There are two types of RSUs: terminal equipment type RSUs, because they are placed on the roadside, the terminal equipment type RSUs are in a non-mobile state and do not need to consider mobility; base station type RSUs can provide timing synchronization to vehicles with which they communicate And resource scheduling.

The embodiments of the present application provide a method of resource allocation, which is applied to the automotive field such as V2X or ADAS, and can be applied to the Internet of Vehicles, such as V2X, LTE-V, V2X, etc. This method is used when sending data of the first service To reduce the probability of collision with other data when the data of the first service is sent.

In the embodiment of the present application, the method of configuring the use probability corresponding to different frequency domain resources for different services may be: 1) pre-set in the terminal device; 2) configured by the base station for the terminal device: the terminal device broadcasts/controls and other messages Read in.

The two setting methods are explained below:

The following specifically refers to FIG. 2, which is a schematic diagram of an embodiment of a method for resource allocation according to an embodiment of the present application, which may include:

201. The terminal device determines the priority of the first service.

In the embodiment of the present application, the terminal device locally presets the correspondence between different services and priorities, and the correspondence can be preset in the terminal device at the factory, or manually afterwards, or set by a high-level application layer or other The device is set, and the corresponding relationship is shown in Table 1. When sending data of the first service, the terminal device adds a priority label to the data according to the corresponding relationship. Among them, in the embodiments of the present application and subsequent embodiments, the priority may be a newly defined service priority, or an existing short-range communication data packet priority (proseper-packet priority, PPPP) priority, specific There is no limitation here. The priority of different services is usually configured through the high-level application layer. For example, the information sent by ambulances to other users requesting to give way has high priority, the information of vehicle emergency braking is second, and the vehicle interaction information sent by ordinary vehicles periodically (such as (Vehicle speed, position, etc.) priority will be lower. The priority of different services can also be manually set, and the terminal device adjusts the priority of different services by responding to user operations.

As shown in Table 1 below, it is a schematic table of the correspondence between different services and priorities (the lower the priority number, the higher the priority of the corresponding service).

business	priority
Ambulance sends information to other users requesting to give way	Priority 1
Vehicle emergency braking information	Priority 2
Vehicle interaction information sent by ordinary vehicles periodically	Priority 3

Table 1

202. The terminal device receives the configuration instruction.

In the embodiment of the present application, the configuration instruction may be an instruction to perform factory setting on the terminal device when the terminal device is shipped from the factory, or an instruction generated by the terminal device in response to a user operation.

203. The terminal device generates resource configuration information according to the configuration instruction, where the resource configuration information includes a correspondence between at least one priority level and a use probability of at least two frequency domain resources, and the at least one priority level includes the priority of the first service.

In the embodiment of the present application, the terminal device generates resource configuration information according to the configuration instruction and stores it locally. The configuration instruction may be a distribution value of the use probability corresponding to each frequency domain resource of each priority level. The configuration instruction may also be a parameter in a mathematical expression of the probability distribution of the use of each priority on different frequency domain resources. As the convention, the mathematical expression is a linear function, and the use of frequency domain resources corresponding to each priority The probability is linearly distributed as the frequency domain resource number increases. The mathematical expression is y=kx+b, y refers to the use probability, x refers to the frequency domain resource number, and k and b are the parameters of the expression. At this time, only k and b in the configuration command need to be transmitted. When sending data of the first service, the terminal device obtains resource configuration information locally. The resource configuration information includes a correspondence between services of different priorities and usage probabilities of at least two frequency domain resources. The correspondence may be as shown in Table 2.

As shown in Table 2 below, it is a schematic table of the correspondence between different priorities and the use probability P(%) of at least two frequency domain resources.

P (%)	Resource 1	Resources 2	Resources 3	Resources 4	Resources 5
Priority 1	P 11	P 12	P 13	P 14	P 15
Priority 2	P 21	P 22	P 23	P 24	P 25
Priority 3	P 31	P 32	P 33	P 34	P 35
Priority 4	P 41	P 42	P 43	P 44	P 45

Table 2

As shown in Table 2, in the resource configuration information, different sequence numbers can be set for different frequency domain resources and different priorities, where the lower the sequence number of the priority, the higher the priority of the corresponding service. It can be understood that, in practice, the priority and the number of frequency domain resources may be set as multiple positive integers, and the specific number is not limited here.

The resource configuration information may include a first usage probability of the at least two frequency domain resources corresponding to the first priority service and a second usage probability of the at least two frequency domain resources corresponding to the second priority service , The first law is different from the second law, the first law is a law that the first usage probability changes with the sequence number of the at least two frequency domain resources, and the second law is that the second usage probability varies with all Describe the change rule of at least two frequency domain resource serial numbers.

The services of various priorities correspond to the use probability of each frequency domain resource and the sequence number of the frequency domain resource. There may be a variety of possible laws, which may be linear or non-linear, which is not specifically limited here.

Specifically, according to the change of the first law and the second law, the description of the resource configuration information may include but is not limited to the following ways:

Manner 1: The resource configuration information includes a first usage probability of the at least two frequency domain resources corresponding to the first priority and a second usage probability of the at least two frequency domain resources corresponding to the second priority. The first usage probability decreases with increasing number of the at least two frequency domain resources, and the second usage probability increases with increasing number of the at least two frequency domain resources.

Exemplarily, in order to reduce the probability of conflict between high-priority services and other services, in the resource configuration information, the probability of setting high-priority services to occupy resources is decreasing as the resource sequence number increases, and low-priority The probability that the service occupies resources increases as the resource sequence number increases. As shown in Table 3 below, the frequency domain resources with a lower sequence number have a higher probability of using high-priority services, the low-priority services have a lower probability of using, and the frequency-domain resources with a higher sequence number have a lower probability of using high-priority services. The probability of using low-priority services is high. For example, services with priority 1 have the highest probability of occupying resource 1, while services with other priorities have the highest probability of occupying resource 5. That is to say, on the same frequency domain resource, the corresponding probabilities of services with different priorities are different, so the collision probability of services with different priorities can be reduced.

P (%)	Resource 1	Resources 2	Resources 3	Resources 4	Resources 5
Priority 1	40	30	20	10	0
Priority 2	0	10	20	30	40
Priority 3	0	0	20	33	47
Priority 4	0	0	0	40	60

table 3

Exemplarily, in order to reduce the probability of conflict between high-priority services and other services, you can also set the probability that high-priority services occupy resources in the resource configuration information as the resource sequence number increases, low priority The probability that a service occupies resources decreases as the number of resources increases. As shown in Table 4 below, the frequency domain resources with a lower sequence number have a lower probability of using high-priority services, the low-priority services have a higher probability of using, and the frequency-domain resources with a higher sequence number have a higher probability of using high-priority services. The probability of using low-priority services is low. For example, the service with priority 1 has the highest probability of occupying resource 5, while the service with other priorities has the highest probability of occupying resource 1. That is to say, on the same frequency domain resource, the corresponding probabilities of services with different priorities are different, so the collision probability of services with different priorities can be reduced.

Manner 2: The resource configuration information includes the first usage probability of the at least two frequency domain resources corresponding to the first priority and the second usage probability of the at least two frequency domain resources corresponding to the second priority. The first usage probability does not change as the sequence numbers of the at least two frequency domain resources increase, the second usage probability increases as the sequence numbers of the at least two frequency domain resources increase, and the priority of the first priority level The priority level is higher than the second priority level.

Exemplarily, in order to reduce the probability of conflict between high-priority services and other services, in the resource configuration information, the probability of setting high-priority services to occupy resources is not to change as the resource sequence number increases, low priority The probability that the service occupies resources increases as the resource sequence number increases. As shown in Table 5 below, priority 1 services have a greater probability of being idle on resources with a lower resource number, and have a lower chance of collision with other low priority services, making it easier to preempt channels.

The first usage probability does not change as the sequence numbers of the at least two frequency domain resources increase, the second usage probability decreases as the sequence numbers of the at least two frequency domain resources increase, and the priority of the first priority level The priority level is higher than the second priority level.

Exemplarily, in order to reduce the probability of conflict between high-priority services and other services, the resource configuration information can be set to set the probability that high-priority services occupy resources as the resource sequence number increases without changing, and low-priority services The probability of occupying resources decreases as the number of resources increases. As shown in Table 6 below, priority 1 services have a greater probability of being idle on resources with a higher resource number, and have a lower chance of collision with other lower priority services, making it easier to preempt channels.

The first usage probability increases with the increase of the at least two frequency domain resource sequence numbers, the second usage probability increases with the increase of the at least two frequency domain resource sequence numbers, and the first usage probability increases with the at least two A frequency domain resource sequence number increments less than the second usage probability increases with the at least two frequency domain resource sequence numbers, the priority level of the first priority is higher than the priority of the second priority level.

Exemplarily, in order to reduce the probability of conflict between high-priority services and other services, in the resource configuration information, the resource usage probabilities of different priorities can be set in an incremental manner (linear), and the increase range of high priority ( (Slope) is less than that of low priority, thereby restricting the freedom of low priority services in resource selection. For example, low priority services can be arranged to resources with high sequence numbers as much as possible, thereby reducing the channel occupied by high priority services The probability of being conflicted by other businesses. As shown in Table 7 below, priority 1 services have a greater probability of being idle on resources with a higher resource number, and have a lower chance of collision with other lower priority services, making it easier to preempt channels.

Optionally, in some possible implementation manners, the resource configuration information may have the following characteristics: among the at least two frequency domain resources, services with different priorities on the same frequency domain resource have different usage probabilities.

Exemplarily, in order to reduce the probability of collision between high-priority services and other services, different frequency domain resources can be set according to different priorities in the resource configuration information, as shown in Table 8 below, if the first priority corresponds Priority 1, the second priority corresponds to priority 4, then the second frequency domain resource includes resource 1 to resource 4, the third frequency domain resource includes resource 4 and resource 5, and the priority 1 service occupies resource 1 alone and has priority Level 4 services can only occupy resources 4 and 5. Since services of different priorities use different frequency domain resources, the probability of collisions between different priority services is reduced.

It should be noted that step 201 and step 202, and step 201 and step 203 have no necessary execution order, and the specific execution order is not limited here.

204. The terminal device determines the use probability of the first service in at least two frequency domain resources according to the priority of the first service and the resource configuration information.

In the embodiment of the present application, the terminal device uses the priority of the first service to query from the resource configuration information and determine the use probability of the first service on resources in different frequency domains.

205. The terminal device determines the first frequency domain resource according to the use probability of the first service in at least two frequency domain resources.

In the embodiment of the present application, after determining the probability of using the first service in different frequency domain resources, the terminal may use a random number method to determine the first frequency domain resources. The first frequency domain resources may be one or more, and may be specifically determined by the terminal The equipment depends on the data volume of the first service. The method for determining the first frequency domain resource may be that the terminal device generates a random number, and then determines the first frequency domain resource according to the random number. Specifically, for example, the usage probability of the frequency domain resources 1-5 corresponding to the first service is 30%, 25%, 20%, 15%, and 10% respectively. Before determining the frequency domain resources, the terminal device randomly generates a 1 -100 random number, if the random number is in the range of (1-30), then the selected first frequency domain resource is frequency domain resource 1, and in turn it can be known that the random numbers corresponding to frequency domain resources 2-5 are ( 31-55), (56-75), (76-90) and (91-100), that is, the terminal device selects the frequency domain resource corresponding to the serial number as the first frequency domain resource according to the generated random number.

Optionally, in some possible implementation manners, the terminal device determines at least two available frequency domain resources whose signal strength is less than a preset threshold, and the preset threshold is a threshold value determined by channel detection to be channel idle; the terminal The device determines the first frequency domain resource according to the at least two available frequency domain resources and the use probability of the first service in the at least two frequency domain resources.

Specifically, before sending the data of the first service, the terminal device may detect the signal strength of each frequency domain resource among all frequency domain resources available to the current terminal device, and select at least two available signals whose signal strength is greater than a preset threshold Frequency domain resources. A frequency domain resource whose signal strength is less than a preset threshold may be regarded as an available frequency domain resource that is “idle”. The preset threshold may be specified in advance through a protocol and stored in the terminal device, or may be sent by the base station in advance to instruct the terminal device to configure. The preset threshold is a threshold for channel detection to determine that the channel is idle value. The signal strength refers to the strength of the signal currently carried on the frequency domain resource. The lower the signal strength, the more the frequency domain resource is "idle" and the better the quality; the higher the signal strength, the frequency domain resource can be considered " The more "occupied" the worse the quality. The better the quality, the lower the interference of data transmission and reception on the frequency domain resources, and the better the delay and reliability. Therefore, by filtering out the first frequency domain resource from the at least two available frequency domain resources, it is beneficial to further improve the reliability of the data for sending the first service.

Exemplarily, as shown in Table 9 below, it is a schematic table of detection results of current states of resources in different frequency domains.

Frequency domain resource number	Preset threshold	Current signal strength	Current status
1	50	20	Available
2	50	55	Occupy
3	50	35	Available
4	50	70	Occupy
5	50	10	Available

Table 9

Further, the terminal device determines the first frequency domain resource according to at least two available frequency domain resources and the use probability of the first service in different frequency domain resources. Specifically, as shown in Table 9, it can be known that frequency domain resources 1, 3, and 5 are available frequency domain resources. If the current usage probability of the first service in the frequency domain resources 1-5 is 30%, 25%, 20%, 15%, and 10%, when the random number generated by the terminal device is 10, the selected first frequency domain The resource is frequency domain resource 1, if it is 35, the corresponding is frequency domain resource 2, the terminal device judges that frequency domain resource 2 is unavailable, and selects again.

206. The terminal device sends the data of the first service through the first frequency domain resource.

In the embodiment of the present application, after determining the first frequency domain resource, the terminal device sends the data of the first service through the first frequency domain resource. Wherein, the receiver of the data of the first service may be a base station, other terminal equipment, or a roadside device, which is not limited herein.

Optionally, in some possible implementation manners, the terminal device may determine resource usage information, and adjust the resource configuration information according to the resource usage information and a preset algorithm. The resource usage information includes data of different priorities. Statistical information sent by two frequency domain resources. The resource usage information may be generated locally by the terminal device. The statistical information may be the correct/failure probability of the terminal device transmitting data on the at least two frequency domain resources, the synchronization frequency domain resource usage probability, the waiting time for transmitting data, and the like.

It is assumed that the resource usage information is statistical information of the failure probability of the terminal device transmitting data on the at least two frequency domain resources. The resource usage information may be as shown in Table 10, which is a schematic table of statistical information of failure results of data with different priorities sent through different frequency domain resources (for illustration only, actual numbers may vary).

Failure probability (%)	Resource 1	Resources 2	Resources 3	Resources 4	Resources 5
Priority 1	0	0.01	0.03	0.02	0
Priority 2	0	0.01	0.02	0.03	0.05
Priority 3	0	0	0.02	0.03	0.05
Priority 4	0	0	0	0.04	0.08

Table 10

It is assumed that the resource usage information illustrated in Table 10 corresponds to the resource configuration information illustrated in Table 3.

Exemplarily, the adjustment process may be to reduce the use probability of services of different priorities corresponding to resources in the frequency domain with a high probability of failure, and increase the use probability of services of different priorities corresponding to resources in the frequency domain with a small probability of failure.

According to the above Table 10, it can be seen that the data of the service of priority 1 has a higher probability of failure through frequency domain resource 3, and the probability of failure on the frequency domain resource 1 is smaller, so the priority 1 service can be increased in the frequency domain resource 1 corresponds to the use probability, and reduces the use probability corresponding to the resource 3 in the frequency domain. Similarly, priority 2, priority 3, and priority 4 can be adjusted separately, and the use probability of each frequency domain resource corresponding to each adjusted priority can be shown in Table 11.

P (%)	Resource 1	Resources 2	Resources 3	Resources 4	Resources 5
Priority 1	50	20	20	10	0
Priority 2	0	20	20	30	30
Priority 3	0	0	40	twenty three	47
Priority 4	0	0	20	30	50

Table 11

Exemplarily, according to the probability distribution in the resource configuration information shown in Table 3, it can be seen that the use probability of the frequency domain resource corresponding to each priority has a linear relationship with the sequence number of the frequency domain resource, and the linear relationship can be expressed by a mathematical expression as y=kx+b, y refers to the probability of use, x refers to the sequence number of the frequency domain resource, and k and b are the parameters of the expression. For example, the expression corresponding to the service of priority 1 in Table 3 is: y=-10x+50, and the expression corresponding to the service of priority 2 is: y=10x-10. Therefore, the adjustment process may also be that the terminal device adjusts the parameters in the "mathematical expression" corresponding to each priority level.

For example, in the correspondence table 10, the distribution of the failure probability of each priority service sending data through different frequency domain resources, the priority 1 service has a lower probability of failure in the frequency domain resource with a lower sequence number and a higher frequency in the sequence number The probability of failure on the domain resource is high, so the expression of priority 1 can be adjusted to: y=-20x+70, increasing the use probability of the service of priority 1 in the frequency domain resource with a lower sequence number, that is, reducing the priority The service of level 1 uses the probability of sending data on the frequency-domain resource with a higher sequence number to reduce the probability of failure of sending the service data of priority 1.

After the terminal device is adjusted, the first frequency domain resource may be determined according to the adjusted resource configuration information.

It can be seen from the above technical solutions that the embodiments of the present application have the following advantages:

When sending data of the first service, the terminal device may determine the use probability of the first service and at least two frequency domain resources according to the priority and resource configuration information of the first service, and determine the first frequency domain resource according to the use probability, and The data of the first service is sent through the first frequency domain resource. Since the resource configuration information indicates the correspondence between different priorities and the use probabilities of at least two frequency domain resources, the different frequency domain resources corresponding to the services of different priorities are determined by using the probabilities, thereby reducing the collision probability of services of different priorities, That is, the probability of collision between high-priority services and low-priority services is reduced.

The following specifically refers to FIG. 3, which is a schematic diagram of another embodiment of a method for resource allocation according to an embodiment of the present application, including:

The network device, that is, the wireless access network device, is an access device in which the terminal device wirelessly accesses the mobile communication system, and may be a base station NodeB, Evolution Type base station eNodeB, base station in 5G mobile communication system, base station in future mobile communication system or access node in WiFi system, etc., the embodiments of the present application are not specific to the specific technology and specific device form adopted by the wireless access network equipment. Be limited. The resource configuration information may be received by another network device or generated by the network device, and the resource configuration information includes a correspondence between services of different priorities and usage probabilities of at least two frequency domain resources. It should be noted that the detailed description of the resource configuration information is similar to the description of the resource configuration information in step 203 of the embodiment shown in FIG. 2, and details are not described here.

Optionally, in some possible implementation manners, the network device may receive the resource usage information sent by the terminal device and generate resource configuration information according to the resource usage information, where the resource usage information includes data of different priority levels currently passing different frequency domain resources Statistics sent.

For example, the resource usage information may be as shown in Table 12, which is a schematic table of statistical information of failure results of data with different priorities transmitted through different frequency domain resources.

Failure probability (%)	Resource 1	Resources 2	Resources 3	Resources 4	Resources 5
Priority 1	0.01	0.01	0.03	0.02	0
Priority 2	0	0.01	0.02	0.03	0.05
Priority 3	0	0	0.02	0.06	0.05
Priority 4	0	0	0	0.04	0.08

Table 12

Assuming that the resource use information illustrated in Table 12 corresponds to the resource configuration information shown in Table 3 in the embodiment shown in FIG. 2, the base station generates resource configuration information according to the resource use message. The process may be that, according to the above Table 12, it can be seen that the data of the service of priority 1 is transmitted through frequency domain resource 3 with a higher probability of failure, while the probability of failure on frequency domain resource 1 is smaller, so priority 1 can be increased The service usage probability corresponding to frequency domain resource 1 reduces the usage probability corresponding to frequency domain resource 3. Similarly, priority 2, priority 3, and priority 4 can be adjusted separately, and the use probability of each frequency domain resource corresponding to each adjusted priority can be shown in Table 13.

P (%)	Resource 1	Resources 2	Resources 3	Resources 4	Resources 5
Priority 1	55	25	10	10	0
Priority 2	0	20	20	30	30
Priority 3	0	0	40	twenty three	47
Priority 4	0	0	0	50	50

Table 13

After that, the network device generates resource configuration information by using the probability distribution of each frequency domain resource corresponding to each adjusted priority.

303. The network device sends resource configuration information to the terminal device.

In the embodiment of the present application, if the terminal device is within the coverage of the network device, the network device sends the resource configuration information to the terminal device through a broadcast or control signaling message. If the terminal device is outside the coverage of the network device, the network device may Forwarded by a second terminal device that has a direct link connection with the terminal device, so that the resource configuration information is sent to the terminal device. Wherein, the second terminal device is within the coverage of the network device.

It should be noted that there is no inevitable execution order of step 301 and step 302 and step 301 and step 303, and the specific execution order is not limited herein.

305. The terminal device determines the first frequency domain resource according to the use probability of the first service in at least two frequency domain resources.

306. The terminal device sends the data of the first service through the first frequency domain resource.

It should be noted that steps 304 to 306 are similar to steps 204 to 206 in the embodiment shown in FIG. 2 and will not be repeated here.

It can be seen from the above technical solutions that the embodiments of the present application have the following advantages:
