Detailed Description

In the embodiment of the application, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, A and/or B, and can mean that A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the LTE-V2X direct link, P-UE senses reserved resources of other UE in a resource sensing window through PARTIAL SENSING, and determines available candidate resources in a resource selection window after collision resources are eliminated. Fig. 1 is a schematic diagram of partial perception in the prior art, in which the subframes filled with diagonal lines in fig. 1 represent candidate subframes, and the subframes filled with diagonal lines represent higher layer parameters minNumCAndidateSF-r14 configured to determine the number Y of candidate subframes.

As shown in fig. 1, the P-UE determines the minimum value of the number Y of candidate subframes according to the higher layer parameter minNumCAndidateSF-r14 configuration, and determines the position of Y subframes in the resource selection window by itself. By monitoringDetermining the current subframe according to the resource occupation result on the subframeWhether it is available. Wherein, Representing the y-th sub-frame,Representing the y-kXP _step sub-frame, P _step is the interval of the sensing opportunities, the set of k values is configured by the higher layer parameters GAPCANDIDATESENSING-r14, k corresponds to the position of 1 of the kth bit of the higher layer parameters GAPCANDIDATESENSING-r 14. For example, in FIG. 1, the higher layer parameter GAPCANDIDATESENSING-r14 is "1100101010".

In the LTE-V2X through link, the P-UE can also allocate resources through random selection. The random selection does not need any perception, and the resources needing to be sent are selected randomly from the candidate resources.

In LTE-V2X direct link Mode 4 resource allocation, for P-UE (allocation of resource pool with only PARTIAL SENSING, only random selection or PARTIAL SENSING or random selection) when the resource pool is PARTIAL SENSING or random selection, the P-UE decides whether to use partial awareness PARTIAL SENSING or randomly select random selection as resource allocation, and for P-UE, selecting random selection resource allocation can save power consumption, and selecting PARTIAL SENSING resource allocation can increase power consumption.

If too many P-UEs in the resource pool select a random selection resource allocation mode in consideration of self power saving, the probability of resource collision in the resource pool can be increased, and PRR is reduced.

In order to solve the problem, the application provides a resource allocation method. Fig. 2 is one of flow diagrams of a resource allocation method provided by the present application, as shown in fig. 2, where an execution body of the method is a terminal, and the terminal may be any P-UE under an LTE-V2X direct link, or may be other terminals under a permission scenario with an autonomous selection resource allocation mode. The resource allocation method comprises the following steps:

Step 210, selecting a resource allocation mode of the through link based on at least one allocation parameter and an allocation rule of each allocation parameter, wherein the allocation parameter is a resource pool collision condition, a resource pool congestion condition, a power saving condition or a preset priority, and the allocation rule is configured by a network side.

Step 220, performing resource allocation based on the resource allocation mode.

Specifically, unlike the scheme that the terminal completely selects the resource allocation mode autonomously at present, conditions, namely at least one allocation parameter and allocation rules of all allocation parameters, are set for the selection of the resource allocation mode of the through link in the application. Here, the allocation parameters are parameters obtained by the terminal and influencing the selection of the resource allocation mode, and each allocation parameter has a corresponding allocation rule for indicating how to select the resource allocation rule under the condition of the current allocation parameter. It should be noted that, the relationship between the allocation parameters and the allocation rules may be one-to-one, or may be that a plurality of allocation parameters correspond to one allocation rule, which is not specifically limited in the embodiment of the present application.

The allocation parameter may be a resource pool collision condition, where the resource pool collision condition is used to reflect a resource collision condition of a resource pool of the direct link, where the resource pool collision condition may be represented by a duty ratio of HARQ NACK (negative acknowledgement) in HARQ (Hybrid Automatic Repeat reQuest ) feedback received by the terminal, or may be represented by a duty ratio of an unavailable resource in candidate resources perceived by the terminal portion. The allocation rule corresponding to the collision situation of the resource pool may be that random selection is selected as the resource allocation mode when the collision situation of the resource pool is less, and partial perception PARTIAL SENSING is selected as the resource allocation mode when the collision situation of the resource pool is more.

The allocation parameter may be a resource pool congestion condition, which is used to reflect the congestion condition of the resource pool of the through link, and the resource pool congestion condition may be reflected by the channel busy rate. The allocation rule corresponding to the resource pool congestion condition may be that random selection is selected as the resource allocation mode when the resource pool congestion condition is light, and partial perception PARTIAL SENSING is selected as the resource allocation mode when the resource pool congestion condition is heavy.

The allocation parameter may be a power saving condition, which may be used to reflect a power saving requirement of the terminal itself, or may be used to reflect a power saving requirement of other terminals, where the power saving condition may be represented by a battery capacity and/or a battery power of each terminal. The allocation rule corresponding to the power saving condition can be that random selection is selected as a resource allocation mode when the power saving requirement of the self is strong, part perception PARTIAL SENSING is selected as a resource allocation mode when the power saving requirement of the self is weak, or part perception PARTIAL SENSING is selected as a resource allocation mode when the power saving requirement of the rest terminal is strong, and random selection is selected as a resource allocation mode when the power saving requirement of the rest terminal is weak.

The allocation parameter may be a preset priority, and the preset priority may be used to reflect the priority of the terminal or the current service executed by the terminal. The allocation rule corresponding to the preset priority may be that random selection is selected as the resource allocation mode when the preset priority is higher, and partial perception PARTIAL SENSING is selected as the resource allocation mode when the preset priority is lower.

The above-mentioned each allocation parameter can be singly matched with its allocation rule to make resource allocation mode selection, also can be several combined and matched with its allocation rule to make resource allocation mode selection, and the specific allocation parameter can be preconfigured by network side, and the allocation rule correspondent to every allocation parameter also can be preconfigured by network side.

After the resource allocation mode is judged, the resource allocation can be performed based on the judged resource allocation mode, so that the resource transmission is realized.

According to the method provided by the embodiment of the invention, the resource allocation mode is selected and the resource allocation is carried out by applying at least one of the collision condition of the resource pool, the congestion condition of the resource pool, the electricity saving condition and the preset priority and the allocation rule of each resource, so that compared with the situation that the terminal autonomously selects the resource allocation mode, the terminal quantity or the proportion of the resource pool for selecting the resource allocation mode randomly is effectively ensured not to exceed the bearable range of the resource pool, the resource collision probability in the resource pool is reduced, and the reliability of resource transmission is ensured.

Based on the above embodiment, step 210 includes:

Step 211, determining candidate resource allocation modes of each allocation parameter based on each allocation parameter and allocation rules of each allocation parameter;

Step 212, determining the resource allocation mode of the through link based on the candidate resource allocation modes of each allocation parameter.

Specifically, for the case that there are multiple allocation parameters for selecting the resource allocation manner of the through link, the candidate resource allocation manner corresponding to each allocation parameter may be obtained based on each independent allocation parameter and the allocation rule corresponding to each independent allocation parameter. The candidate resource allocation method refers to a resource allocation method obtained by analyzing and judging only a single allocation parameter and allocation rules of each allocation parameter.

For example, for the case of collision of the resource pool, it is assumed that the case of collision of the resource pool indicates that there are more resource collisions, and in combination with an allocation rule corresponding to the case of collision of the resource pool, it can be determined that the candidate resource allocation mode is partially perceived PARTIAL SENSING from the perspective of the case of collision of the resource pool, and for the case of power saving, it is assumed that the power saving condition indicates that the current power saving requirement of the terminal is stronger, and in combination with an allocation rule corresponding to the case of power saving, it can be determined that the candidate resource allocation mode is randomly selected from the perspective of the case of power saving. It can be seen that, when there are a plurality of allocation parameters, the candidate resource allocation methods of the allocation parameters may be the same or different.

After the candidate resource allocation manners of each allocation parameter are obtained, the final resource allocation manner can be determined by combining the candidate resource allocation manners of each allocation parameter, for example, if the candidate resource allocation manners of all allocation parameters are random selection, the resource allocation manner is determined to be random selection, and if the candidate resource allocation manner of one allocation parameter is partial perception PARTIAL SENSING, namely, the resource allocation manner is determined to be partial perception PARTIAL SENSING, for example, the number of times that the candidate resource allocation manner is random selection and the number of times that the candidate resource allocation manner is partial perception PARTIAL SENSING can be counted, and the party with larger number of times is selected as the resource allocation manner.

Based on any of the above embodiments, the resource pool collision situation comprises a resource collision value, the resource collision value being determined based on the hybrid automatic repeat request, HARQ, feedback measurement or a partial awareness result.

Here, the resource collision value is used to quantify the resource pool collision situation, and the higher the resource collision value, the more resource collisions occur in the resource pool, and the lower the resource collision value, the fewer the resource collisions occur in the resource pool. The calculation of the resource collision value can be realized by the statistics of the duty ratio of the number of HARQ NACK in the HARQ feedback in the total number of HARQ feedback, and can also be obtained by partially sensing the duty ratio of the unavailable resource reflected in the obtained result in the candidate resource.

When the at least one allocation parameter includes a resource pool collision, step 211 includes:

If the resource collision value is larger than the collision threshold value, determining that the candidate resource allocation mode of the resource pool collision condition is partial perception;

otherwise, determining the candidate resource allocation mode of the collision condition of the resource pool as random selection.

Here, the collision threshold is a threshold that is preset to measure whether there are fewer or more resource collision situations indicated by the resource collision value. A collision threshold set may be configured in advance according to the maximum number of receivable HARQ feedback and resource pool configuration, and a collision threshold is configured for each resource pool by the network side, where the configured collision threshold may be selected from the collision threshold set, and the network side may refer to the size of the resource pool and requirements of reliability when configuring the collision threshold.

Specifically, the situation that the resource collision value is larger than the collision threshold value indicates that the resource collision condition in the resource pool is more, at the moment, the terminal should select part perception PARTIAL SENSING so as to avoid the occurrence of more resource collision conditions and ensure the reliability of resource transmission, and the situation that the resource collision value is smaller than or equal to the collision threshold value indicates that the resource collision condition in the resource pool is less, at the moment, the terminal can select random selection, so that the self-electricity quantity is saved as much as possible under the condition that the resource collision probability in the resource pool is relatively low.

Based on any of the above embodiments, before step 211 is performed, the following steps are further required to be performed to determine a resource collision value:

Determining a resource collision value based on the duty ratio of negative acknowledgement NACK in the HARQ feedback received in a preset period;

Specifically, the resource collision value may be obtained through HARQ feedback measurement, or may be obtained through a partial sensing result:

For the HARQ feedback measurement, the number of HARQ feedback times [ n-T, n ] received in a preset period and the number of HARQ NACK times in the received HARQ feedback may be counted, so as to calculate the duty ratio of HARQ NACK in HARQ, and determine the duty ratio as a resource collision value. Wherein n represents any time, and T is the duration of a preset period. In addition, for the retransmitted HARQ feedback, a weight greater than 1 may be set for the HARQ NACK feedback, so that when the number of HARQ NACKs is counted, the number of times of the retransmitted HARQ NACK feedback is accumulated according to the weight thereof, for example, the current accumulated number of HARQ times is 10, wherein the number of HARQ NACKs is 3, at this time, the retransmitted HARQ NACK feedback is received, the number of HARQ NACKs is updated to 4.3 times according to the retransmission weight of 1.3, and the number of HARQ times is updated to 11.3 times.

For the partial sensing result, the number of the unavailable resources obtained by partial sensing can be counted, the number of the unavailable resources is divided by the total number of the candidate resources, the duty ratio of the unavailable resources is obtained, and the duty ratio is determined as a resource collision value.

Based on any of the embodiments above, the resource pool congestion condition includes a channel busy rate CBR.

Here, CBR (Channel Busy Ratio, channel busy rate) is used to quantify the resource pool congestion situation, and the higher the CBR value, the more serious the resource congestion situation occurs in the resource pool, and the lower the CBR value, the lighter the resource congestion situation occurs in the resource pool. The CBR here may be a value within a preset period of time n-T, n.

When at least one allocation parameter includes a resource pool congestion condition, step 211 includes:

If CBR is larger than the congestion threshold value, determining that the candidate resource allocation mode of the congestion condition of the resource pool is partially perceived;

Here, the congestion threshold is a threshold that is preset to measure whether the congestion condition of the resource pool indicated by the CBR value is relatively slight or relatively serious. A congestion threshold set can be configured in advance according to the requirements of system QoS (Quality of Service ) and resource pool configuration, and a congestion threshold is configured for each resource pool by a network side, wherein the configured congestion threshold can be selected from the congestion threshold set, and the network side can refer to the requirements of the size, reliability and the like of the resource pool when the congestion threshold is configured.

Specifically, the situation that the CBR is larger than the congestion threshold value indicates that the resource congestion condition in the resource pool is serious, at the moment, the terminal should select part of sensing PARTIAL SENSING so as to avoid more resource congestion conditions and ensure the reliability of resource transmission, and the situation that the CBR is smaller than or equal to the congestion threshold value indicates that the resource congestion condition in the resource pool is slight, at the moment, the terminal can select random selection, and the electric quantity of the terminal can be saved as much as possible.

Based on any of the above embodiments, the power saving condition includes a local power saving demand level, the local power saving demand level being determined based on a battery capacity and/or a battery margin of the local terminal.

Here, the power saving requirement level of the home terminal is used to quantify the power saving requirement of the home terminal, and the home terminal is the execution subject of the resource allocation method, i.e. the current terminal. The power saving requirement level of the home terminal is defined according to the battery capacity and/or the battery allowance of the corresponding terminal, and the power saving requirement level of the home terminal is executed:

The power saving requirement level can be defined according to the battery capacity of the terminal, for example, the power saving requirement level of the terminal with the battery capacity of 0-1000 mAh is 8, the power saving requirement level of the terminal with the capacity of 1000-2000 mAh is 7, and the power saving requirement level of the terminal with the capacity of 7000-800 mAh is 1. Terminals with capacities greater than 8000mAh do not need to save power, and the power saving requirement level can be set to 0 level.

The power saving requirement level can be defined according to the battery allowance of the terminal, for example, the power saving requirement level of the terminal with the power allowance of 0-1000 mAh is 8, the power saving requirement level of the terminal with the power allowance of 1000-2000 mAh is 7, and the power saving requirement level of the terminal with the power allowance of 7000-800 mAh is 1. Terminals with a margin greater than 8000mAh do not need to save power, and the power saving requirement level can be set to 0 level.

The power saving requirement level can be defined by combining the battery capacity and the battery margin of the terminal, for example, the power saving requirement level of the terminal with the battery capacity of 0-1000 mAh is 8, the power saving requirement level of the terminal with the battery capacity of 1000-2000 mAh and the power margin of 0-1000 mAh is 8, and the power saving requirement level of the terminal with the battery capacity of 1000-2000 mAh and the power margin of 1000-2000 mAh is 7.

When the at least one allocation parameter includes a power saving condition, step 211 includes:

if the power saving requirement level of the local terminal is lower than the first power saving level threshold, determining that the candidate resource allocation mode of the power saving condition is partial perception;

Otherwise, the candidate resource allocation mode of the electricity saving condition is determined to be selected randomly.

Here, the first power saving level threshold is a threshold that is preset to measure whether the power saving requirement of the home terminal indicated by the power saving requirement level of the home terminal is stronger or weaker. A first set of power saving level thresholds may be configured in advance according to the power saving requirements of the terminals, and a first power saving level threshold may be configured for each resource pool by the network side, the first power saving level threshold configured here may be selected from a first power saving level threshold set, and the network side may be configured with reference to a congestion degree of the resource pool, a reliability requirement, and the like when performing configuration of the first power saving level threshold.

Specifically, the situation that the power saving requirement level of the local end is lower than the first power saving level threshold value indicates that the current power saving requirement of the terminal is not strong, at the moment, the terminal should select part of perception PARTIAL SENSING, the occurrence of more resource congestion is avoided while power saving opportunities are provided for other terminals, the reliability of resource transmission is ensured, and the situation that the power saving requirement level of the local end is higher than or equal to the first power saving level threshold value indicates that the current power saving requirement of the terminal is stronger, at the moment, the terminal can select random selection, and the self electric quantity is saved as much as possible.

For example, if the first power saving level threshold is 5 levels, the terminals with power saving requirement levels of 5,6,7 and 8 may perform resource allocation through random selection, and the terminals with power saving requirement levels lower than 5 levels perform PARTIAL SENSING resource allocation.

Based on any of the above embodiments, the power saving situation includes a power saving requirement level of the remaining terminals.

Here, the power saving requirement levels of the remaining terminals are used to quantify the power saving requirements of the remaining terminals, which refer to terminals other than the home terminal. The determination manner of the power saving requirement level of the remaining terminals may refer to the determination manner of the power saving requirement level of the home terminal in the foregoing embodiment, for example, the determination manner is defined by the battery capacity and/or the battery margin of the corresponding terminal, which is not described herein.

If the power-saving terminal duty ratio is larger than the power-saving terminal proportion threshold value, determining that the candidate resource allocation mode of the power-saving condition is partial perception;

otherwise, determining the candidate resource allocation mode of the electricity saving condition as random selection;

Here, the second power saving level threshold is a threshold set in advance for measuring whether the power saving requirement of the terminal indicated by the power saving level is strong or weak. A second set of power saving level thresholds may be configured in advance according to the power saving requirements of the terminals, and a second power saving level threshold may be configured for each resource pool by the network side, the second power saving level threshold configured here may be selected from a second set of power saving level thresholds, and the network side may be configured with reference to the congestion level of the resource pool, the reliability requirement, and the like when performing the configuration of the second power saving level threshold. The second power saving level threshold value may be the same as or different from the first power saving level threshold value.

The power saving terminal proportion threshold is a preset threshold for measuring whether the proportion of the terminals with stronger power saving requirements is more or less, a power saving terminal proportion threshold set can be configured in advance according to configuration information of the resource pools, and a power saving terminal proportion threshold is configured for each resource pool by the network side.

Specifically, after the power saving requirement level of each remaining terminal is known, the power saving requirement level of each remaining terminal may be compared with the second power saving level threshold, so as to count the number of remaining terminals, i.e., the number of power saving terminals, whose power saving requirement level is greater than or equal to the second power saving level threshold. On the basis, the ratio of the number of the power-saving terminals to the total number of the rest terminals is calculated and used as the node terminal duty ratio.

Further, the power saving requirement level applied to each of the remaining terminals calculated herein may be acquired by the home terminal during a preset period of time [ n-T, n ]. Assuming that the second power saving level threshold is Q, the number of power saving terminals, i.e., the number of remaining terminals whose power saving demand level is greater than or equal to Q.

The situation that the proportion of the electricity-saving terminal is larger than the proportion threshold value of the electricity-saving terminal indicates that more terminals needing electricity saving exist at present, the terminal should select part perception PARTIAL SENSING, the situation that more resources are congested is avoided while electricity saving opportunities are provided for other terminals, the reliability of resource transmission is guaranteed, the situation that the proportion of the electricity-saving terminal is smaller than or equal to the proportion threshold value of the electricity-saving terminal indicates that the terminals needing electricity saving at present are not more, at the moment, the terminal can select random selection, and the electric quantity of the terminal can be saved as much as possible.

Based on any of the above embodiments, before step 211 is performed, the following steps are further required to be performed to obtain the power saving requirement level of the remaining terminals:

the power saving requirement level of the corresponding terminal is extracted from the SCI.

Specifically, in order to facilitate terminals to be able to know each other's power saving requirement level, selection of a resource allocation manner is facilitated. Each terminal can report its own power saving requirement level carried in SCI (Sidelink Control Information, through link control information). Taking the current terminal as an example, when the current terminal performs partial sensing, SCIs sent by other terminals can be obtained, and the power saving requirement level of the other terminals can be obtained from the SCIs.

Further, the power saving requirement level of the N bit bearer terminals can be applied in the 1st stage SCI, and the power saving requirement level of the N bit bearer terminals in the 2nd stage SCI can also be applied, where N is the number of bits that the power saving requirement level needs to occupy.

Based on any of the above embodiments, the preset priority is a local priority, or a priority of executing the service by the local terminal.

When the at least one allocation parameter includes a preset priority, step 211 includes:

otherwise, determining the candidate resource allocation mode of the preset priority as random selection.

Here, the priority threshold is a preset threshold that measures whether the preset priority is higher or lower. A set of priority thresholds may be configured in advance, based on the resource pool configuration information, and a priority threshold may be configured by the network side for each resource pool, the priority threshold configured here may be selected from a priority threshold set, and when the network side configures the priority threshold, the network side may refer to the requirements of the size, reliability, etc. of the resource pool for configuration.

Specifically, the case that the preset priority is smaller than the priority threshold indicates that the preset priority of the terminal does not meet the condition of random selection, the terminal should select part of sensing PARTIAL SENSING to provide power saving opportunity for the terminal with the preset priority higher than the priority threshold, and the case that the preset priority is larger than or equal to the priority threshold indicates that the preset priority of the terminal meets the condition of random selection, and the terminal can select random selection to save self electric quantity.

Based on any of the above embodiments, step 212 includes:

Otherwise, determining the resource allocation mode of the through link as random selection.

Specifically, for the situation that at least two allocation parameters jointly participate in the selection of the resource allocation mode, as long as the candidate resource allocation mode corresponding to any one allocation parameter is the partial perception, that is, when the terminal should select the partial perception from the perspective of any one allocation parameter, the resource allocation mode of the direct link of the terminal can be directly determined to be the partial perception PARTIAL SENSING. Only if the candidate resource allocation modes corresponding to all allocation parameters are randomly selected, determining that the resource allocation mode of the direct link of the terminal is randomly selected.

The method provided by the embodiment of the invention effectively ensures that the number or the proportion of the terminals for selecting the random selection resource allocation mode in the resource pool does not exceed the bearable range of the resource pool by combining a plurality of allocation parameters to limit the selection of the resource allocation mode, reduces the collision probability of the resources in the resource pool and ensures the reliability of the resource transmission.

Based on any of the above embodiments, the method for allocating resources based on a single allocation parameter and allocation rule thereof includes:

the terminal calculates the duty ratio of the HARQ NACK in the HARQ feedback received in a preset period or the duty ratio of the unavailable resource in the candidate resources according to part of the perception result to obtain a resource collision value, compares the resource collision value with a collision threshold value, determines a resource allocation mode based on the comparison result, and allocates the resources;

or the terminal calculates to obtain CBR in a preset period, compares the CBR with a congestion threshold value, determines a resource allocation mode based on a comparison result, and allocates resources;

or the terminal compares the power saving requirement level of the terminal with a first power saving level threshold value, determines a resource allocation mode based on the comparison result, and allocates resources;

Or the terminal obtains the electricity-saving demand level of the other terminals, calculates the duty ratio of the electricity-saving terminal based on the electricity-saving demand level of the other terminals and the second electricity-saving level threshold, compares the duty ratio of the node terminal with the proportion threshold of the electricity-saving terminal, determines a resource allocation mode based on the comparison result, and allocates resources;

Or the terminal compares the preset priority with a priority threshold, determines a resource allocation mode based on the comparison result, and allocates the resources.

Based on any of the above embodiments, the method for jointly allocating resources based on two allocation parameters and allocation principles corresponding to the two allocation parameters respectively includes:

The terminal selects a resource allocation mode of the direct link and performs resource allocation based on any two of a resource pool collision condition, a resource pool congestion condition, a power saving condition and a preset priority and allocation rules corresponding to the two conditions.

For example, resource allocation may be performed in combination with a resource pool collision situation and a resource pool congestion situation:

And when the measured collision value of the resources is larger than the collision threshold value or/and the measured CBR is larger than the congestion threshold value, the terminal allocates the resources through PARTIAL SENSING.

And when the measured collision value of the resources is smaller than the collision threshold value and the measured CBR is smaller than the congestion threshold value, the terminal allocates the resources through random selection.

For another example, the resource allocation may be performed in combination with the resource pool congestion condition and the power saving demand level of other terminals in the power saving condition:

and when the measured CBR is greater than the congestion threshold value or/and the measured node terminal duty ratio is greater than the power saving terminal proportion threshold value, the terminal allocates the resources through PARTIAL SENSING.

And when the measured CBR is smaller than the congestion threshold value and the measured node terminal duty ratio is smaller than the power saving terminal proportion threshold value, the terminal performs resource allocation through random selection.

For another example, the resource allocation may be performed in combination with a resource pool congestion situation and a preset priority:

and when the measured CBR value is larger than the congestion threshold value or/and the preset priority is lower than the priority threshold value, the terminal allocates resources through PARTIAL SENSING.

And when the measured CBR value is smaller than the congestion threshold value and the preset priority is higher than the priority threshold value, the terminal allocates resources through random selection.

For another example, the resource allocation may be performed in combination with the power saving requirement level of other terminals in the resource pool collision situation and the power saving situation:

and when the measured resource collision value is greater than the collision threshold value or/and the measured node terminal duty ratio is greater than the power-saving terminal proportion threshold value, the terminal allocates the resources through PARTIAL SENSING.

And when the measured resource collision value is smaller than the collision threshold value or/and the measured node terminal duty ratio is smaller than the power-saving terminal proportion threshold value, the terminal performs resource allocation through random selection.

For another example, the resource allocation may be performed in combination with a collision situation of the resource pool and a preset priority:

And when the measured resource collision value is greater than the collision threshold value or/and the preset priority is lower than the priority threshold value, the terminal allocates the resources through PARTIAL SENSING.

And when the measured resource collision value is smaller than the collision threshold value or/and the preset priority is higher than the priority threshold value, the terminal allocates the resources through random selection.

For another example, the resource allocation may be performed in combination with the power saving requirement level and the preset priority level of other terminals in the power saving situation:

And if the measured node terminal duty ratio is greater than the power-saving terminal proportion threshold value or/and the preset priority is lower than the priority threshold value, the terminal allocates the resources through PARTIAL SENSING.

And if the measured node terminal duty ratio is smaller than the power-saving terminal proportion threshold or/and the preset priority is higher than the priority threshold, the terminal performs resource allocation through random selection.

Based on any one of the above embodiments, the method for jointly allocating resources based on three allocation parameters and allocation principles corresponding to the three allocation parameters respectively includes:

The terminal selects a resource allocation mode of the direct link and performs resource allocation based on any three of a resource pool collision condition, a resource pool congestion condition, a power saving condition and a preset priority and corresponding allocation rules thereof.

For example, the resource allocation may be performed in combination with a resource pool collision situation, a resource pool congestion situation, and a preset priority:

When the measured collision value of the resources is smaller than the collision threshold value, the measured CBR value is smaller than the congestion threshold value, and the preset priority is higher than the priority level threshold value, the terminal allocates the resources through random selection.

In other cases (i.e. as long as there is a candidate resource allocation mode determined by an allocation parameter is PARTIAL SENSING) that do not satisfy the above conditions, the terminal performs resource allocation through PARTIAL SENSING.

For another example, the resource allocation may be performed in combination with a resource pool congestion condition, a power saving demand level of other terminals in the power saving condition, and a preset priority level:

When the measured CBR is smaller than the congestion threshold value, the measured node terminal duty ratio is smaller than the power-saving terminal proportion threshold value, and the preset priority is higher than the priority level threshold value, the terminal performs resource allocation through random selection.

For another example, the resource allocation may be performed in combination with the resource pool collision condition, the resource pool congestion condition, and the power saving demand level of other terminals in the power saving condition:

When the measured collision value of the resources is smaller than the collision threshold value, the measured CBR value is smaller than the congestion threshold value, and the measured node terminal duty ratio is smaller than the power-saving terminal proportion threshold value, the terminal performs resource allocation through random selection.

For another example, the resource allocation may be performed in combination with the collision situation of the resource pool, the power saving requirement level of other terminals in the power saving situation, and the preset priority level:

When the measured resource collision value is smaller than the collision threshold, the measured node terminal duty ratio is smaller than the power-saving terminal proportion threshold, and the preset priority is higher than the priority level threshold, the terminal performs resource allocation through random selection.

Based on any of the above embodiments, fig. 3 is a second flowchart of a resource allocation method provided by the present application, and as shown in fig. 3, an execution body of the method is a network side, and the method includes:

Step 310, determining an allocation rule of at least one allocation parameter, wherein the allocation parameter is a resource pool collision condition, a resource pool congestion condition, a power saving condition or a preset priority;

step 320, configuring an allocation rule of at least one allocation parameter for the terminal, so that the terminal selects a resource allocation mode of the through link based on the allocation rule of the at least one allocation parameter and the allocation parameter corresponding to each allocation rule, and performs resource allocation based on the resource allocation mode.

Before the terminal selects the resource allocation mode based on at least one allocation parameter and the allocation rules of each allocation parameter, the network side is required to firstly determine the allocation rule used by the terminal for selecting the resource allocation mode, and configure the allocation rule to the terminal, namely, what kind of allocation parameter is specifically adopted for selecting the resource allocation mode, and the allocation rule corresponding to each allocation parameter is required to be preconfigured by the network side.

The allocation parameters selected by the network side and used for selecting the resource allocation mode may be a resource pool collision condition, where the resource pool collision condition is used for reflecting the resource collision condition of the resource pool of the direct link, and the resource pool collision condition may be represented by the duty ratio of HARQ NACK (negative acknowledgement) in the feedback of HARQ (Hybrid Automatic Repeat reQuest ) received by the terminal, or may be represented by the duty ratio of unavailable resources in the candidate resources perceived by the terminal portion. The allocation rule corresponding to the collision situation of the resource pool may be that random selection is selected as the resource allocation mode when the collision situation of the resource pool is less, and partial perception PARTIAL SENSING is selected as the resource allocation mode when the collision situation of the resource pool is more.

The allocation parameters selected by the network side and used for selecting the resource allocation mode may be the congestion situation of the resource pool, where the congestion situation of the resource pool is used to reflect the congestion situation of the resource pool of the through link, and the congestion situation of the resource pool may be reflected by the busy rate of the channel. The allocation rule corresponding to the resource pool congestion condition may be that random selection is selected as the resource allocation mode when the resource pool congestion condition is light, and partial perception PARTIAL SENSING is selected as the resource allocation mode when the resource pool congestion condition is heavy.

The allocation parameters selected by the network side and used for selecting the resource allocation mode can be power saving conditions, the power saving conditions can be used for reflecting the power saving requirements of the terminals and the power saving requirements of other terminals, and the power saving conditions can be represented by the battery capacity and/or the battery electric quantity of each terminal. The allocation rule corresponding to the power saving condition can be that random selection is selected as a resource allocation mode when the power saving requirement of the self is strong, part perception PARTIAL SENSING is selected as a resource allocation mode when the power saving requirement of the self is weak, or part perception PARTIAL SENSING is selected as a resource allocation mode when the power saving requirement of the rest terminal is strong, and random selection is selected as a resource allocation mode when the power saving requirement of the rest terminal is weak.

The allocation parameters selected by the network side and used for selecting the resource allocation mode may be preset priority, where the preset priority may be used to reflect the priority of the terminal or the current executing service of the terminal. The allocation rule corresponding to the preset priority may be that random selection is selected as the resource allocation mode when the preset priority is higher, and partial perception PARTIAL SENSING is selected as the resource allocation mode when the preset priority is lower.

The above-mentioned each allocation parameter can be singly matched with its allocation rule to make resource allocation mode selection, also can be several combinations and matched with its allocation rule to make resource allocation mode selection, and can be singly applied or combined applied, and the allocation rule when singly applied or combined applied can be respectively determined by network side, then can be configured into the terminal.

After receiving the allocation rule configured by the network side, the terminal can select a resource allocation mode and allocate resources by combining the allocation rule configured by the network side and the corresponding allocation parameters of each allocation parameter, thereby realizing resource transmission.

Based on any of the above embodiments, step 310 includes:

Specifically, for each allocation parameter, a rule threshold set of each allocation parameter may be set separately.

For example, the rule threshold corresponding to the resource pool collision condition is a collision threshold. Here, the collision threshold is a threshold that is preset to measure whether there are fewer or more resource collision situations indicated by the resource collision value. A collision threshold set may be configured in advance according to the maximum number of receivable HARQ feedback and the resource pool configuration, etc. as a rule threshold set for the resource pool collision situation. After that, the network side may configure a collision threshold for each resource pool, where the configured collision threshold may be selected from a set of collision thresholds, and when the network side performs configuration of the collision threshold, the network side may perform configuration with reference to requirements of the size, reliability, and the like of the resource pool.

For example, the collision threshold set is {0.3,0.4,0.5,0.6}, and the network side may configure the collision threshold for the resource pool to be 0.5.

The rule threshold corresponding to the congestion condition of the resource pool is a congestion threshold. Here, the congestion threshold is a threshold that is preset to measure whether the congestion condition of the resource pool indicated by the CBR value is relatively slight or relatively serious. A set of congestion thresholds may be pre-configured as a set of rule thresholds for resource pool congestion conditions based on system QoS requirements, resource pool configuration, etc. After that, the network side may configure a congestion threshold for each resource pool, where the configured congestion threshold may be selected from the congestion threshold set, and when the network side performs configuration of the congestion threshold, the network side may perform configuration with reference to requirements of the size, reliability, and the like of the resource pool.

For example, the congestion threshold set is {0.4,0.5,0.6,0.7}, and the network side may configure the congestion threshold for the resource pool to be 0.6.

And in the power saving situation, the rule threshold corresponding to the power saving requirement level of the local terminal is a first power saving level threshold. Here, the first power saving level threshold is a threshold that is preset to measure whether the power saving requirement of the home terminal indicated by the power saving requirement level of the home terminal is stronger or weaker. The first power saving level threshold set can be configured in advance according to the power saving requirement of each terminal to serve as a rule threshold set of the power saving condition of the local terminal. Thereafter, the network side may configure a first power saving level threshold for each resource pool, where the configured first power saving level threshold may be selected from the first power saving level threshold set, and the network side may configure the first power saving level threshold with reference to a congestion degree of the resource pool, a reliability requirement, and the like when configuring the first power saving level threshold.

The rule threshold corresponding to the power saving requirement level of the rest terminals in the power saving situation comprises a second power saving level threshold and a power saving terminal proportion threshold:

here, the second power saving level threshold is a threshold set in advance for measuring whether the power saving requirement of the terminal indicated by the power saving level is strong or weak. A second set of power saving level thresholds may be configured in advance according to the power saving requirements of the terminals as a set of regular thresholds for the power saving terminals. Thereafter, the network side may configure a second power saving level threshold for each resource pool, where the configured second power saving level threshold may be selected from the second power saving level threshold set, and the network side may configure the second power saving level threshold with reference to the congestion degree of the resource pool, the reliability requirement, and the like when configuring the second power saving level threshold. The second power saving level threshold value may be the same as or different from the first power saving level threshold value.

The power saving terminal proportion threshold is a preset threshold for measuring whether the proportion of terminals with stronger power saving demands is more or less, and a power saving terminal proportion threshold set can be configured in advance according to configuration information of a resource pool to serve as a rule threshold set of the node terminal proportion in the power saving condition. Thereafter, the network side may configure a power saving terminal proportion threshold for each resource pool, where the configured power saving terminal proportion threshold may be selected from a power saving terminal proportion threshold set, and the network side may configure the power saving terminal proportion threshold with reference to the size of the resource pool, the reliability requirement, and the like.

For example, the power saving terminal proportion threshold set is {0.3,0.4,0.5,0.6,0.7}, and the network side may configure the power saving terminal proportion threshold for the resource pool to be 0.6.

The rule threshold corresponding to the preset priority is a priority threshold. Here, the priority threshold is a preset threshold that measures whether the preset priority is higher or lower. A priority threshold set may be configured in advance according to the resource pool configuration information as a rule threshold set of preset priorities. After that, the network side may configure a priority threshold for each resource pool, where the configured priority threshold may be selected from the priority threshold set, and when the network side configures the priority threshold, the network side may configure the priority threshold with reference to the requirements of the size, reliability, and the like of the resource pool.

For example, the set of priority thresholds is {3,4,5,6,7}, and the network side may configure the resource pool with a priority threshold of 7.

In the method provided by the embodiment of the invention, in the resource pools supporting different resource allocation modes, the resource allocation mode of the terminal is determined according to one or more combinations of the collision condition of the resource pools, the congestion condition of the resource pools, the electricity-saving condition and the preset priority. And adjusting the resource allocation mode of the terminal according to at least one of the configured collision threshold, congestion threshold, power saving level threshold, power saving terminal proportion threshold and priority threshold. The method and the device avoid the situation that the terminal autonomously selects the resource allocation mode, ensure that the number or the proportion of the terminals selecting the random selection resource allocation mode in the resource pool does not exceed the range which can be born by the system, thereby reducing the collision probability of the resources in the resource pool and ensuring the reliability of the resource transmission.
