Description

Resource allocation method, terminal equipment and network equipment
Technical Field
The present application relates to the field of communications, and in particular, to a method for resource allocation, a terminal device, and a network device.
Background
Vehicle to arbitrary objects (V2X), i.e., car networking technology, was successfully established as one of the main applications of device to device (D2D) technology in the release of the standardized specification Rel-14/15/16 set by the third generation partnership project (3 GPP). In the V2X scenario, the traffic of V2X may be provided over the PC5 interface and the Uu interface. The PC5 interface is an interface defined on the basis of a direct link (sidelink), and communication transmission can be directly performed between terminal devices by using the PC5 interface. In the V2X through link Mode, the resource allocation Mode can be divided into a base station scheduling Mode (Mode3) and a terminal device autonomous selection Mode (Mode 4). In the terminal device autonomous selection mode, collision easily occurs between different terminal devices, that is, different terminal devices may select the same frequency domain resource to transmit service data. The frequency domain resource with the collision bears the service data of different terminal devices, and the different service data affect each other, so that the time delay and reliability of data transmission on the frequency domain resource are affected. The service data can be divided according to priority, and the requirements of different priorities on the network are different, wherein the service data with high priority has higher requirements on the time delay and reliability of data transmission, and the collision condition is to be avoided.
In the prior art, in order to avoid the occurrence of a collision situation, when a terminal device autonomously selects a resource (Mode4), firstly, a sensing (sensing) Mode is adopted to determine 20% of idle resources of a system, and then, the terminal device randomly selects a frequency domain resource from the 20% of idle resources to transmit service data. Specifically, the terminal device determines, by detecting that the current signal energy of the channel is compared with a set threshold and an energy threshold corresponding to the current service of the channel: and if the terminal equipment detects that the signal energy on a certain channel is smaller than the energy threshold corresponding to the current service of the channel and is smaller than the threshold, determining that the channel is idle resource.
When the low-priority service in the system occupies a large amount of resources, the energy threshold corresponding to the corresponding resources is also high, and the terminal device determines that 20% of the resources in the idle state, the detected threshold needs to be continuously increased, so that channel resources occupied by some low-priority services are also identified as idle resources. If the channel resources are utilized to send the data of the high-priority service later, the low-priority service and the high-priority service collide in the channel, so that the signal-to-noise ratio of the data of the high-priority service is reduced, and a receiving end needs to process the data of the high-priority service and the data of the low-priority service simultaneously on the channel, so that the time delay of the high-priority service is increased, and the reliability of the high-priority service is reduced.
Disclosure of Invention
The embodiment of the application discloses a resource allocation method, which is applied to the automobile field of V2X or Advanced Driving Assistance Systems (ADAS) and the like, can be applied to the Internet of vehicles, such as V2X, LTE-V and the like, and is used for reducing the probability of data collision with other services when data of a first service is transmitted.
In view of this, a first aspect of the embodiments of the present application provides a method for resource allocation, which may include:
in a scenario of V2X, when the terminal device sends data of the first service, the terminal device first determines a priority of the first service and obtains resource configuration information. The corresponding relation between different services and priorities may be preset in the terminal device when leaving factory, or set by manual or high-level application layer or other devices. The first traffic may be high priority traffic or low priority traffic. The resource configuration information includes a correspondence between at least one priority including a priority of the first service and a usage probability of at least two frequency domain resources. After determining the priority of the first service, the terminal device may determine, according to the priority of the first service and the resource configuration information, a usage probability corresponding to each frequency domain resource of the at least two frequency domain resources for the first service. Thus, the terminal device may determine the first frequency-domain resource from the at least two frequency-domain resources according to the usage probability. And finally, the terminal equipment sends the data of the first service through the first frequency domain resource. In the embodiment of the present application, a method for resource allocation is provided, where when sending data of a first service, a terminal device determines, according to a priority of the first service, a usage probability of the first service on at least two frequency domain resources, and further determines, according to the usage probability, a first frequency domain resource, and finally, the terminal device sends the data of the first service by using the first frequency domain resource. Different services can set different use probabilities according to different priorities, so that the collision probability among the services is avoided.
In a possible design, the resource allocation 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, where the first rule is different from a second rule, the first rule is a rule in which the first usage probability changes as the sequence numbers of the at least two frequency domain resources increase, and the second rule is a rule in which the sequence numbers of the second usage probability change as the sequence numbers of the at least two frequency domain resources increase. In the embodiment of the present application, resource configuration information is further described: the resource configuration information can be flexibly configured, the rules of the at least two frequency domain resources corresponding to different priorities are different, and the diversity of the scheme is increased.
In one possible design, the service probabilities corresponding to services of different priorities on the same frequency domain resource in the at least two frequency domain resources are different. In the embodiment of the present application, resource configuration information is further described: in the resource configuration information, the service probabilities corresponding to services with different priorities on the same frequency domain resource in at least two frequency domain resources are different, and the service probability can be set to be 0% -100%, so that the diversity of the scheme is increased.
In one possible design, the method may include: the terminal equipment determines at least two available frequency domain resources with signal strength smaller than a preset threshold value, wherein the preset threshold value is a threshold value judged to be idle by channel detection; the terminal equipment determines a first frequency domain resource according to the use probability of the first service in at least two frequency domain resources, and the method comprises the following steps: the terminal equipment determines the first frequency domain resource according to the at least two available frequency domain resources and the usage probability of the first service in the at least two frequency domain resources. In the embodiment of the application, at least two available frequency domain resources with small signal intensity are screened out by setting a preset threshold, and then a first frequency domain resource is selected from the at least two available frequency domain resources. The frequency domain resource with the signal strength smaller than the preset threshold value can be regarded as an available frequency domain resource which is "idle". The preset threshold may be defined in advance by a protocol and stored in the terminal device, or may be configured by the base station sending a signaling in advance to indicate the terminal device, where the preset threshold is a threshold determined as being idle by channel detection. The signal strength refers to the strength of a signal currently carried on the frequency domain resource, and the lower the signal strength is, the more the frequency domain resource is idle, the better the quality is; the higher the signal strength is, the more the frequency domain resource is occupied, the poorer the quality is, the less the interference encountered by data transmission and reception on the frequency domain resource with better quality is, and the better the time-delay and the reliability are. Therefore, by screening out the first frequency domain resource from the at least two available frequency domain resources, it is beneficial to further improve the reliability of transmitting the data of the first service.
In one possible design, the obtaining, by the terminal device, the resource configuration information includes: the terminal device receives the resource configuration information from the network device.

In the embodiment of the application, a generation mode of resource configuration information is provided, and the diversity of the scheme is increased.
In one possible design, the obtaining, by the terminal device, the resource configuration information includes: the terminal equipment receives a configuration instruction; and the terminal equipment generates the resource configuration information according to the configuration instruction. The configuration instruction may be a distribution value of the usage probability corresponding to each frequency domain resource for each priority. The configuration instruction may also be a parameter in a mathematical expression of distribution of the usage probability of each priority on different frequency domain resources, for example, if the mathematical expression is a straight-line function, the usage probability of the frequency domain resources corresponding to each priority is linearly distributed along with the increasing probability of the frequency domain resource sequence number, where the mathematical expression is y ═ kx + b, y denotes the usage probability, x denotes the sequence number of the frequency domain resource, and k and b are parameters of the expression, respectively. At this time, the configuration command only needs to transmit k and b. In the embodiment of the application, another generation mode of resource configuration information is provided, and the diversity of the scheme is increased.
In one possible design, the method may include: the terminal equipment determines resource use information, wherein the resource use information comprises statistical information sent by data with different priorities through the at least two frequency domain resources; and the terminal equipment adjusts the resource configuration information according to the resource use information. In the embodiment of the application, the terminal can adjust the resource configuration information according to the current resource use information, and a method for updating the resource configuration information is provided, so that the scheme is more complete.

Detailed Description
A method for resource allocation and a network device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Mobile communication technology has profoundly changed people's lives, but the pursuit of higher performance mobile communication technology has never stopped. In order to cope with explosive mobile data traffic increase, massive mobile communication device connection, and various new services and application scenarios which are continuously emerging in the future, the fifth generation mobile communication system (5G) has come into force. The International Telecommunications Union (ITU) defines three broad classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), high-reliability and low-latency communications (URLLC), and massive machine type communications (mtc).
The D2D technology refers to a technology for directly transmitting data between neighboring devices in a communication network. In the 5G system, there is a higher demand for the terminal devices of the nodes of the D2D communication network, and the terminal device of each user node can send and receive signals and has an automatic routing (message forwarding) function. Once the D2D communication link is established, data can be directly transmitted between different nodes without passing through an intermediate entity, so that the pressure of a core network of a communication system can be reduced, the frequency spectrum utilization rate and the throughput are greatly improved, and the network capacity is expanded.

RSUs include two types: the RSU of the terminal equipment type is distributed on the roadside, so that the RSU of the terminal equipment type is in a non-mobile state and does not need to consider mobility; the RSU, being of the base station type, can provide timing synchronization and resource scheduling to the vehicle with which it communicates.

Priority 1 P11 P12 P13 P14 P15
Priority 2 P21 P22 P23 P24 P25
Priority 3 P31 P32 P33 P34 P35
Priority 4 P41 P42 P43 P44 P45
TABLE 2
As shown in table 2, in the resource allocation information, different sequence numbers may 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 is understood that, in practice, the number of the priority and the frequency domain resource may be set to a plurality of positive integers, and the specific number is not limited herein.
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, where the first rule is different from the second rule, the first rule is a rule that the first usage probability varies with the at least two frequency domain resource sequence numbers, and the second rule is a rule that the second usage probability varies with the at least two frequency domain resource sequence numbers.
The service probability of each priority corresponding to each frequency domain resource and the sequence number of the frequency domain resource may have various possible rules, which may be linear rules or non-linear rules, and the specific details are not limited herein.
Specifically, according to the change of the first rule and the second rule, the description of the resource configuration information may include, but is not limited to, the following ways:
the first method is as follows: 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 usage probability decreases with the increase of the at least two frequency domain resource sequence numbers, and the second usage probability increases with the increase of the at least two frequency domain resource sequence numbers.
For example, in order to reduce the probability of collision between the high-priority traffic and other traffic, in the resource configuration information, the probability that the high-priority traffic occupies the resource is set to decrease as the resource sequence number increases, and the probability that the low-priority traffic occupies the resource is set to increase as the resource sequence number increases. As shown in table 3 below, on the frequency domain resource with a lower sequence number, the probability of using the high priority service is high, and the probability of using the low priority service is low, while on the frequency domain resource with a higher sequence number, the probability of using the high priority service is low, and the probability of using the low priority service is high. For example, traffic of priority 1 has the highest probability of occupying resource 1, while traffic of other priorities has the highest probability of occupying resource 5. That is, the service probabilities of the services with different priorities are different in the same frequency domain resource, so that the collision probability of the services with different priorities can be reduced.
P(%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 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
For example, in order to reduce the probability of collision between the high-priority service and other services, it may also be set in the resource configuration information that the probability that the high-priority service occupies the resource is increased as the resource sequence number is increased, and the probability that the low-priority service occupies the resource is decreased as the resource sequence number is increased. As shown in table 4 below, on the frequency domain resource with a lower sequence number, the probability of using the high priority service is low, and the probability of using the low priority service is high, while on the frequency domain resource with a higher sequence number, the probability of using the high priority service is high, and the probability of using the low priority service is low. For example, traffic of priority 1 has the highest probability of occupying resource 5, while traffic of other priorities has the highest probability of occupying resource 1. That is, the service probabilities of the services with different priorities are different in the same frequency domain resource, so that the collision probability of the services with different priorities can be reduced.
P(%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 5
Priority 1 0 10 20 30 40
Priority 2 40 30 20 10 0
Priority 3 47 33 20 0 0
Priority 4 60 40 0 0 0
TABLE 4
The second method comprises the following steps: 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 usage probability does not change 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 a priority level of the first priority is higher than a priority level of the second priority.
For example, in order to reduce the probability of collision between the high-priority traffic and other traffic, in the resource configuration information, the probability that the high-priority traffic occupies the resource may be set to be unchanged as the resource sequence number increases, and the probability that the low-priority traffic occupies the resource may be increased as the resource sequence number increases. As shown in table 5 below, the service with priority 1 has a higher idle probability on the resource with a low resource number, and has a lower probability of collision with other services with low priority, so that it is easier to seize the channel.
P(%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 5
Priority 1 20 20 20 20 20
Priority 2 10 15 20 25 30
Priority 3 4 12 20 28 36
Priority 4 0 10 20 30 40
TABLE 5
The third method comprises the following steps: 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 usage probability does not change with the increase of the at least two frequency domain resource sequence numbers, the second usage probability decreases with the increase of the at least two frequency domain resource sequence numbers, and a priority level of the first priority is higher than a priority level of the second priority.
For example, in order to reduce the probability of collision between the high-priority traffic and other traffic, it may be set in the resource configuration information that the probability that the high-priority traffic occupies the resource does not change as the resource sequence number increases, and the probability that the low-priority traffic occupies the resource decreases as the resource sequence number increases. As shown in table 6 below, the service with priority 1 has a higher idle probability on the resource with the higher resource number, and has a lower probability of collision with other services with lower priorities, so that it is easier to seize the channel.
P(%) Resource 1 Resource 2 Resource(s)3 Resource 4 Resource 5
Priority 1 20 20 20 20 20
Priority 2 30 25 20 15 10
Priority 3 36 28 20 12 4
Priority 4 40 30 20 10 0
TABLE 6
The method is as follows: 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 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, the increasing amplitude of the first usage probability with the at least two frequency domain resource sequence numbers is smaller than the increasing amplitude of the second usage probability with the at least two frequency domain resource sequence numbers, and the priority level of the first priority is higher than the priority level of the second priority.
For example, in order to reduce the collision probability between high-priority traffic and other traffic, the resource usage probabilities of different priorities may be set in an incremental (linear) manner in the resource configuration information, and the increase amplitude (slope) of high priority is smaller than that of low priority, so as to limit the freedom of resource selection for low-priority traffic, for example, low-priority traffic may be arranged as much as possible on the resource with high sequence number, so as to reduce the probability of collision by other traffic when the high-priority traffic occupies the channel. As shown in table 7 below, the service with priority 1 has a higher idle probability on the resource with the higher resource number, and has a lower probability of collision with other services with lower priorities, so that it is easier to seize the channel.
P(%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 5
Priority 1 18 19 20 21 22
Priority 2 16 18 20 22 24
Priority 3 14 17 20 23 26
Priority 4 10 15 20 25 30
TABLE 7
Optionally, in some possible implementation manners, the resource configuration information may have the following characteristics: and the service probabilities corresponding to services with different priorities on the same frequency domain resource in the at least two frequency domain resources are different.
For example, in order to reduce the collision probability between a high priority service and other services, different frequency domain resources may be set according to different priorities in the resource configuration information, as shown in table 8 below, if the first priority corresponds to priority 1, and the second priority corresponds to priority 4, the second frequency domain resources include resources 1 to 4, the third frequency domain resources include resources 4 and 5, the service of priority 1 occupies resource 1 alone, and the service of priority 4 can only occupy resources 4 and 5, since the frequency domain resources used by the services of different priorities are different, the collision probability of the services of different priorities is reduced.
P(%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 5
Priority 1 20 20 20 20 20
Priority 2 0 10 20 30 40
Priority 3 0 0 20 33 47
Priority 4 0 0 0 20 80
TABLE 8
It should be noted that, the steps 201 and 202, and the steps 201 and 203 do not have to be executed in any order, and the specific execution order is not limited herein.
204. And the terminal equipment 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 application, the terminal device queries the resource configuration information by using the priority of the first service, and determines the use probability of the first service on different frequency domain resources.
205. The terminal equipment determines the first frequency domain resource according to the using probability of the first service in at least two frequency domain resources.
In this embodiment of the present application, after determining the usage probability of the first service in different frequency domain resources, the terminal may determine the first frequency domain resources by using a random number method, where the first frequency domain resources may be one or more, and may specifically be determined by the terminal device according to 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 probabilities of the frequency domain resources 1 to 5 corresponding to the first service are 30%, 25%, 20%, 15%, and 10%, respectively, the terminal device randomly generates a random number of 1 to 100 before determining the frequency domain resources, and if the random number is in the range of (1 to 30), the selected first frequency domain resource is the frequency domain resource 1, and it can be sequentially known that the random numbers corresponding to the frequency domain resources 2 to 5 are (31 to 55), (56 to 75), (76 to 90), and (91 to 100), that is, the terminal device selects the frequency domain resource corresponding to the sequence 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 strengths are smaller than a preset threshold, where the preset threshold is a threshold determined to be idle by channel detection; and the terminal equipment 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 the terminal device sends the data of the first service, the terminal device may detect the signal strength of each frequency domain resource in all frequency domain resources that can be used by the current terminal device, and select at least two available frequency domain resources whose signal strengths are greater than a preset threshold. The frequency domain resource with the signal strength smaller than the preset threshold value can be regarded as an available frequency domain resource which is "idle". The preset threshold may be defined in advance by a protocol and stored in the terminal device, or may be configured by the base station sending a signaling in advance to indicate the terminal device, where the preset threshold is a threshold determined as being idle by channel detection. The signal strength refers to the strength of a signal currently carried on a frequency domain resource, and the lower the signal strength is, the more the frequency domain resource is idle, the better the quality is; the higher the signal strength, the more "occupied" the frequency domain resource may be considered to be of poor quality. The better the quality, the less the interference of data receiving and transmitting on the frequency domain resource, the better the time ductility and reliability. Therefore, by screening out the first frequency domain resource from the at least two available frequency domain resources, it is beneficial to further improve the reliability of transmitting the data of the first service.
Illustratively, as shown in table 9 below, it is a schematic table of the current state detection results of different frequency domain resources.
Frequency domain resource sequence number Preset threshold value Current signal strength Current state
1 50 20 Can be used
2 50 55 Occupancy
3 50 35 Can be used
4 50 70 Occupancy
5 50 10 Can be used
TABLE 9
Further, the terminal device determines the first frequency domain resource according to the at least two available frequency domain resources and the usage probability of the first service in different frequency domain resources. Specifically, as shown in table 9, it can be known that the frequency domain resources 1, 3, and 5 are available frequency domain resources. If the corresponding usage probability of the current 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 resource is frequency domain resource 1, and if the random number is 35, the selected first frequency domain resource is frequency domain resource 2, the terminal device determines that the frequency domain resource 2 is unavailable, and performs selection again.
206. And the terminal equipment transmits the data of the first service through the first frequency domain resource.
In the embodiment of the application, after determining the first frequency domain resource, the terminal device sends the data of the first service through the first frequency domain resource. The receiver of the first service data may be a base station, or may be 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, where the resource usage information includes statistical information sent by the data with different priorities through at least two frequency domain resources, and the resource usage information may be locally generated by the terminal device. The statistical information may be a correct/fail probability of the terminal device transmitting data on the at least two frequency domain resources, a synchronous frequency domain resource usage probability, a waiting time for transmitting data, and the like.
The resource usage information is assumed to be statistical information of the probability of failure of the terminal device to transmit 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 of different priorities transmitted through different frequency domain resources (for example only, actual numbers may be different).
Failure probability (%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 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
Watch 10
It is assumed that the resource usage information shown in table 10 corresponds to the resource configuration information shown in table 3.
For example, the adjustment process may be to reduce the usage probability of the different priority services corresponding to the frequency domain resource with the high failure probability and increase the usage probability of the different priority services corresponding to the frequency domain resource with the low failure probability.
As can be seen from table 10, the probability of failure of the data of the priority 1 service transmitted via frequency domain resource 3 is high, and the probability of failure in frequency domain resource 1 is low, so that the probability of use of the priority 1 service in frequency domain resource 1 can be increased, and the probability of use in frequency domain resource 3 can be decreased. Similarly, the priority 2, the priority 3, and the priority 4 may be adjusted, and the usage probability of each frequency domain resource corresponding to each adjusted priority may be as shown in table 11.
P(%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 5
Priority 1 50 20 20 10 0
Priority 2 0 20 20 30 30
Priority 3 0 0 40 23 47
Priority 4 0 0 20 30 50
TABLE 11
For example, as can be seen from the probability distribution in the resource configuration information shown in table 3, the usage probability of the frequency domain resource corresponding to each priority is in a linear relationship with the sequence number of the frequency domain resource, and the linear relationship can be expressed by a mathematical expression of y ═ kx + b, y denotes the usage probability, x denotes the sequence number of the frequency domain resource, and k and b are parameters of the expression, respectively. For example, the expression corresponding to the service of priority 1 in table 3 is: y is-10 x +50, and the expression corresponding to the service of priority 2 is as follows: y is 10 x-10. Therefore, the adjusting process may also be that the terminal device adjusts parameters in the "mathematical expression" corresponding to each priority.
For example, in the correspondence table 10, the distribution of the failure probability of the service of each priority transmitting data through different frequency domain resources is that the failure probability of the service of priority 1 on the frequency domain resource with the lower sequence number is lower and the failure probability on the frequency domain resource with the higher sequence number is higher, so the expression of priority 1 may be adjusted to: and y is-20 x +70, the use probability of the service with the priority level 1 on the frequency domain resource with the lower sequence number is increased, namely, the probability that the service with the priority level 1 transmits data on the frequency domain resource with the higher sequence number is reduced, and the failure probability of the transmission of the service data with the priority level 1 is reduced.
After the terminal device adjusts, the first frequency domain resource may be determined according to the adjusted resource configuration information.
According to the technical scheme, the embodiment of the application has the following advantages:
when the terminal device sends the data of the first service, the terminal device may determine the usage probability of the first service and the at least two frequency domain resources according to the priority of the first service and the resource configuration information, determine the first frequency domain resources according to the usage probability, and then send the data of the first service through the first frequency domain resources. Because the resource configuration information indicates the corresponding relation between the use probabilities of different priorities and at least two frequency domain resources, the different frequency domain resources corresponding to the services with different priorities are determined by the use probabilities, so that the collision probability of the services with different priorities is reduced, namely the collision probability of the services with high priority and the services with low priority is reduced.
Referring to fig. 3 in detail, fig. 3 is a schematic diagram of another embodiment of a method for resource allocation in an embodiment of the present application, including:
301. the terminal equipment determines the priority of the first service.
It should be noted that step 301 is similar to step 201 in the embodiment shown in fig. 2, and is not described here again.
302. The network equipment determines resource configuration information, wherein the resource configuration information comprises a corresponding relation between at least one priority and the use probabilities of at least two frequency domain resources, and the at least one priority comprises the priority of the first service.
In the embodiment of the present application, the network device is preset with resource configuration information, and the network device, that is, the radio access network device, is an access device that the terminal device accesses to the mobile communication system in a wireless manner, and may be a base station NodeB, an evolved base station eNodeB, a base station in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, and the like. The resource configuration information may be sent by receiving another network device, or generated by the network device, where the resource configuration information includes a correspondence between services of different priorities and the usage probabilities of at least two frequency domain resources. It should be noted that the detailed description of the resource allocation information is similar to the description of the resource allocation information in step 203 of the embodiment shown in fig. 2, and is not repeated here.
Optionally, in some possible implementation manners, the network device may receive 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 statistical information that data of different current priorities are sent through different frequency domain resources.
For example, the resource usage information may be a schematic table of statistical information of failure results of data of different priorities transmitted through different frequency domain resources, as shown in table 12.
Failure probability (%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 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 usage information shown in table 12 corresponds to the resource allocation information shown in table 3 in the embodiment shown in fig. 2, the base station generates the resource allocation information according to the resource usage message. As can be seen from table 12, the probability of failure of the data of the priority 1 service transmitted through the frequency domain resource 3 is high, and the probability of failure on the frequency domain resource 1 is low, so that the probability of use of the priority 1 service on the frequency domain resource 1 can be increased, and the probability of use on the frequency domain resource 3 can be decreased. Similarly, the priority 2, the priority 3, and the priority 4 may be adjusted, and the usage probability of each frequency domain resource corresponding to each adjusted priority may be as shown in table 13.
P(%) Resource 1 Resource 2 Resource 3 Resource 4 Resource 5
Priority 1 55 25 10 10 0
Priority 2 0 20 20 30 30
Priority 3 0 0 40 23 47
Priority 4 0 0 0 50 50
Watch 13
And then, the network equipment generates resource configuration information by using the adjusted use probability distribution condition of each frequency domain resource corresponding to each priority.
303. And the network equipment sends the resource configuration information to the terminal equipment.
In this 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, and if the terminal device is outside the coverage of the network device, the network device may forward the resource configuration information to the terminal device through a second terminal device having a direct link connection with the terminal device. Wherein the second terminal device is within the coverage of the network device.
It should be noted that, the execution order of steps 301 and 302, and steps 301 and 303 are not necessarily limited, and the specific execution order is not limited herein.
304. And the terminal equipment 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.
305. The terminal equipment determines the first frequency domain resource according to the using probability of the first service in at least two frequency domain resources.
306. And the terminal equipment transmits 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 are not repeated here.
According to the technical scheme, the embodiment of the application has the following advantages:
when the terminal equipment sends the data of the first service, the network equipment sends resource configuration information to the terminal equipment, so that the terminal equipment can determine the use probabilities of the first service and at least two frequency domain resources according to the priority of the first service and the resource configuration information, determine the first frequency domain resources according to the use probabilities, and further send the data of the first service through the first frequency domain resources. Because the resource configuration information indicates the corresponding relation between the use probabilities of different priorities and at least two frequency domain resources, the different frequency domain resources corresponding to the services with different priorities are determined by the use probabilities, so that the collision probability of the services with different priorities is reduced, namely the collision probability of the services with high priority and the services with low priority is reduced.
