Description

Resource allocation method, network side equipment and terminal

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a resource allocation method, a network side device, and a terminal.

Background

For long term evolution (Long Term Evolution, LTE) -Vehicle-to-outside information exchange (V2X) service, there are two resource allocation methods for User Equipment (UE, also called a terminal): a scheduling-based resource allocation method and an automatic selection resource allocation (automotic resource selection) method. For UEs using the automatic selection resource allocation method, the resource allocation is in resource pools, one resource pool comprising several sub-channels (sub-channels), one sub-channel comprising a plurality of physical resource blocks (Physical Resource Block, PRBs). The automatic selection resource allocation method can be used for resource allocation whether the terminal is in the coverage area of the large network or not. The terminal obtains the corresponding resource pool configuration information according to the different states in the following three modes:

1) For terminals in an IDLE state (rrc_idle) or a CONNECTED state (rrc_connected) within the coverage of the large network, a series of resource pool configuration information may be broadcasted for all terminals by broadcasting a system information block (System Information Block, SIB) 21 through the base station;

2) For terminals in the rrc_connected state within the coverage area of the large network, the base station may include resource pool configuration information in a radio resource control (Radio Resource Control, RRC) reconfiguration message;

3) And pre-configuring a series of resource pool configuration information for the terminal through a base station or terminal pre-configuration form.

The terminal in the standard selects one resource pool among a series of configured resource pools for transmission and reception of control signaling (control) and data (data). The specific selection method is as follows:

(1) If there is a geographical area configuration message (zone-configuration) in the resource configuration information in SIB21, the RRC reconfiguration message or the pre-configuration message, the terminal selects a single resource pool according to its own geographical area to transmit control and data using a one-to-one mapping relationship between the resource pool and the geographical location (zone) in the configuration message.

(2) If there is no geographical area configuration message (zone-config) in the resource configuration message, the UE randomly selects the first resource pool from the configured resource pool list for transmission and reception.

After the resource pool is defined, the UE can select the corresponding subshannel based on a random selection or partial sensing (partial sensing) mode; in the physical layer transmitting process, the terminal selects a sub-channel with reference signal received power (Reference Signal Receiving Power, RSRP) smaller than or equal to a threshold and smaller direct mode reference signal strength indication (S-RSSI) as a candidate sub-channel for transmitting and receiving data.

However, in the existing standard, after defining the resource pool, the subchannel, PRB resource sensing and scheduling scheme of each terminal in the resource pool does not consider the time factor, but in the actual environment, the number of vehicles in different dates and different time periods is greatly changed, for example: road segment A is busy during the early peak 7:30-9:30 and the late peak 5:30-7:30 of the weekday, and is idle during the rest of the weekday and the rest of the weekday. The existing resource allocation method may cause that the channel ratio in some resource pools is high in the peak period, and the channel ratio in some resource pools is low in the flat peak period or the low peak period, or the channel ratio in some resource pools is high in some period, and the channel ratio in other resource pools is low, so that the communication requirement of the terminal cannot be met.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the invention, fall within the scope of protection of the invention.

Referring to fig. 1, fig. 1 is a flowchart of a resource allocation method according to a first embodiment of the present invention, where the method is applied to a network device, and includes the following steps:

step 11: generating resource configuration information corresponding to a plurality of time periods according to the first information reported by the terminal; the first information is reported to the network side equipment by the terminal under the condition that the terminal meets a preset trigger condition;

Step 12: and transmitting the resource configuration information corresponding to the time period to the terminal in each time period.

According to the resource allocation method provided by the embodiment of the invention, the resource allocation information allocated by the network side equipment is related to the time factor, so that the problem of resource congestion can be solved, and the resources under the condition of non-congestion can be adjusted, thereby ensuring that all terminals can transmit and receive data normally.

In the above embodiment, the first information may be minimization of drive tests (Minimization of drive-tests, MDT) information.

In the above embodiment, the period may be set according to actual requirements, for example: 2 hours, 1 minute, 10 milliseconds, etc., and is more flexible and convenient.

In the above embodiment, the plurality of time periods may be a plurality of time periods within a specified period, and the specified period may be set according to actual requirements, for example: the time periods in one day and the time periods in one week are more flexible and convenient.

In the embodiment of the present invention, there are various preset triggering conditions, and the following is exemplified.

That is, the reason for triggering the terminal to report the first information is a first trigger condition, a second trigger condition, or a third trigger condition, that is, when the terminal meets any one of the first trigger condition, the second trigger condition, and the third trigger condition, the first information is reported to the network side device. If the terminal is in a connection state and has available resources, immediately reporting first information to network side equipment; if the terminal is not in the connection state at present, reporting first information to the network side equipment when the terminal enters the connection state next time.

For a first trigger condition, for example, at a time point t1 (yy-mm-dd-hh-mm-ss), a subframe n1, where the priority of the service of location1 is k1, and the selected resource pool is RP1, the terminal calculates a channel ratio accumulation sum of all services with priority less than or equal to k1 in the subframe n1-a, n1+b ], and if the channel ratio accumulation sum is greater than cr_limit corresponding to the priority of k1 (the cr_limit may be located in a resource configuration message broadcasted by a network side device, an RRC reconfiguration message sent by the network side device, or a resource configuration message preconfigured by the terminal or the network side device), the UE a generates first information, where the first information includes: t1, location1, a resource pool RP1, a priority k1, a channel duty accumulation sum, and cr_limit, determining that a first trigger condition is met, and reporting the first information to a network side device, where the first information further includes: triggering UE A to report the reason of the first information: a first trigger condition.

For a second trigger condition, for example, at a time point t4 (yy-mm-dd-hh-mm-ss), a subframe n4 is located in the geographic location4, and data transmitted by another terminal through a PC5 port is received at the resource pool RP4, and according to the through mode control information (Sidelink control information, SCI), the data priority is obtained as k4, but the packet loss rate of the UE D on the RP4 is greater than a first preset proportion, and/or the false detection rate is greater than a second preset proportion (i.e., the UE D cannot demodulate the received data on the RP 4), the UE D generates first information, where the first information includes: t4, positioning 4, a resource pool RP4, and a priority k4, determining that the second trigger condition is met, and reporting the first information to the network side device, where the first information further includes: triggering UE D to report the reason of the first information: and a second trigger condition.

For the third triggering condition, for example, when the UE E selects resources from the resource pool RP5 at the time point t5 (yy-mm-dd-hh-mm-ss), the subframe n5 is located in the geographic location position 5, if the number of remaining subchannels is smaller than the preset threshold after excluding the subchannels with RSRP greater than the first preset power threshold, the available candidate resources are fewer, which indicates that the possible congestion may be caused by traffic congestion on RP5, or that the first preset power threshold is not reasonable, and the UE E generates first information including: t5, location5, a resource pool RP5, determining that a third trigger condition is met, and reporting the first information to a network side device, where the first information further includes: triggering UE E to report the reason of the first information: and a third trigger condition.

In other embodiments of the present invention, the third trigger condition may also be that a ratio of the candidate resource screened by the terminal from the reported resource pool to the resource pool is smaller than a preset ratio threshold.

Taking UE E as an example, if the proportion of the remaining subchannels to RP5 is smaller than the preset proportion threshold (e.g., 20%) after excluding the subchannels with RSRP greater than the first preset power threshold, the third trigger condition is satisfied, and the first information is reported to the network side device.

The time point for reporting the first information includes: reporting the date and the specific time.

The first service is a service which occurs on a reported resource pool at a time point when the terminal reports the first information and at a geographic position of the terminal at the time point.

The preset triggering condition is the reason for triggering the terminal to report the first information.

In the embodiment of the invention, the resource configuration information corresponding to a plurality of time periods in a designated period can be generated according to the first information reported by the terminal in a preset period. For example: generating resource configuration information corresponding to different geographic positions and a plurality of time periods in a day according to all first information reported by a plurality of terminals in a week or a month, for example: for a geographic location, at the early peak 7:00-9:00 and the late peak 17:00-19:00 of the workday, larger resources are allocated for the resource pool corresponding to the geographic location.

The resource configuration information corresponding to a preset time period can also be generated according to the first information reported by the terminal in the preset time period. For example: the resource pool corresponding to another geographic location is not congested at ordinary times, but in the present day 13:00-13:30, numerous terminals continuously report the resource pool, which indicates that larger resources may be configured for the resource pool corresponding to the geographic location in the next time period (e.g. 13:30-14:00) due to traffic congestion occurring in the geographic location.

In some preferred embodiments of the present invention, before step 11, further comprising:

transmitting original resource configuration information to the terminal, wherein the original resource configuration information comprises at least one of the following components:

Mapping relation between the initially configured resource pool and the geographic position;

the size of the initially configured resource pool;

a bitmap (bitmap) corresponding to the initially configured resource pool;

a first preset power threshold value for selecting resources is configured for the services with different priorities;

a second preset power threshold for measuring channel occupancy;

mapping relation between service priority and channel duty ratio threshold.

Specifically, the mapping relationship between the initially configured resource pool and the geographic location may be a one-to-one mapping relationship between the resource pool and the geographic location.

In the bitmap corresponding to the initially configured resource pool, if a certain bit in the bitmap is 1, the subframe corresponding to the bit is used for service transmission.

The first preset power threshold is used for the terminal to select resources according to the perceived RSRP of the current resources. If the RSRP of the current resource is larger than a first preset power threshold, indicating that the current resource is unavailable; and if the RSRP of the current resource is smaller than or equal to the first preset power threshold value, indicating that the current resource is available.

The second preset power threshold is used for the terminal to determine whether the current resource is full, whether the current priority traffic can be carried, and may be an RSRP threshold for calculating a channel busy ratio (channel busy rate, CBR). If the current resources are full, resources for lower priority traffic than the current priority may be sacrificed to ensure that high priority traffic (i.e., current priority traffic) has sufficient available resources.

For example, the initially configured geographic location M corresponds to a resource pool M, on which the UE selects resources for transceiving of current traffic data. The UE can sense the RSRP of the sub-channels on the resource pool m and exclude the sub-channels with the RSRP larger than a first preset power threshold value; then detecting the S-RSSI of a sub-channel with the RSRP smaller than or equal to a first preset power threshold value, and selecting the sub-channel with smaller S-RSSI (with lower interference of the sub-channel with smaller S-RSSI) as a resource for the UE to transmit and receive; verifying whether the load of the selected resource is too high, and calculating the channel duty ratio of the selected resource according to a second preset power threshold, namely calculating the proportion of sub-channels of which RSRP exceeds the second preset power threshold in a certain time period; if the calculated proportion value is larger than the channel duty ratio threshold corresponding to the current service, the selected resource load is too high, the UE needs to report the first information again, and the network side equipment needs to carry out resource allocation again.

For each priority traffic, a first preset power threshold, a second preset power threshold and/or a channel duty cycle threshold may be corresponding. For example, the priority of the service a and the service B is 1, the priority of the service C is 2, the service a and the service B correspond to a first preset power threshold, a second preset power threshold and/or a channel duty ratio threshold corresponding to the priority 1, and the service C corresponds to a first preset power threshold, a second preset power threshold and/or a channel duty ratio threshold corresponding to the priority 2.

The original resource configuration information can be carried by SIB broadcasted by the network side equipment to the terminal, or carried by RRC reconfiguration information sent by the network side equipment to the terminal, or the original resource configuration information preconfigured by the network side equipment for the terminal.

Of course, in other preferred embodiments of the present invention, the terminal may also be preconfigured with the original resource configuration information, which is not limited by the present invention.

In an embodiment of the present invention, the step of generating the resource configuration information corresponding to the plurality of time periods includes at least one of:

adjusting the size of a resource pool;

adjusting a bitmap corresponding to the resource pool;

adjusting a first preset power threshold corresponding to the first service;

adjusting a second preset power threshold corresponding to the first service;

Specifically, the resizing of the resource pool may be expanding or contracting the resource pool.

The terminal at the geographic position Y is more than the terminal at the geographic position X (i.e. congestion is more likely to occur at the geographic position Y than at the geographic position X), under the condition that the total bandwidth is 20MHz, the initially configured resource pool X corresponding to the geographic position X is 5MHz bandwidth, and the resource pool Y corresponding to the geographic position Y is 15MHz bandwidth, however, the terminal at the geographic position Y still reports the first information continuously within a period of time, the resource pool Y can be enlarged to 18MHz bandwidth, the resource pool X is reduced to 2MHz bandwidth, i.e. part of resources in the initially configured resource pool X are not mapped to the geographic position X any more and are mapped to the geographic position Y.

The bitmap corresponding to the resource pool is adjusted to be 1 by adjusting more bits in the bitmap, so that more subframes are allocated to the first service, which is equivalent to expanding the resource pool; or more bits in the bitmap are adjusted to 0, so that fewer subframes are allocated for the first service, which is equivalent to reducing the resource pool.

Adjusting a first preset power threshold corresponding to the first service comprises increasing the first preset power threshold corresponding to the first service, and reducing sub-channels with RSRP larger than the first preset power threshold, namely reducing excluded sub-channels and increasing candidate sub-channels by increasing the first preset power threshold; the method further comprises the step of reducing a first preset power threshold corresponding to the first service, wherein the number of the excluded sub-channels is increased, and the number of the candidate sub-channels is reduced.

Adjusting a second preset power threshold corresponding to the first service comprises increasing the second preset power threshold corresponding to the first service, and by increasing the second preset power threshold, the proportion of sub-channels of which RSRP exceeds the second preset power threshold is reduced, and the situation that the first information needs to be reported again is reduced; the method also comprises the steps of reducing a second preset power threshold corresponding to the first service, increasing the proportion of sub-channels with RSRP exceeding the second preset power threshold, and increasing the situations of re-reporting the first information.

Adjusting the channel duty ratio threshold corresponding to the first service comprises improving the channel duty ratio threshold corresponding to the first service, and the situation that the first information needs to be reported again is reduced by improving the channel duty ratio threshold; the method also comprises the step of reducing the channel duty ratio threshold corresponding to the first service, and the situation that the first information needs to be re-reported is increased.

In the prior art, a configuration scheme of a specific resource pool corresponding to different time periods and different geographic positions is not standardized, and network side equipment lacks effective theoretical basis for calculating resource pool configuration information, and the configuration scheme comprises the following steps: the method comprises the following steps of calculating theoretical basis of parameters such as the size of a resource pool, the mapping relation between the resource pool and a geographic position, the mapping relation between the resource pool and a time period, and the RSRP threshold value of CBR.

In the embodiment of the invention, the network side equipment can generate the resource configuration information corresponding to the actual situation by one or more modes according to the actual situation (namely, different geographic positions, different dates, change of the number of vehicles in different time periods and the like), so that the situation that the channel ratio in some resource pools is high and the channel ratio in other resource pools is low can be avoided, the problem of resource congestion can be solved, and the resources under the condition of no congestion can be adjusted, thereby ensuring that all terminals can transmit and receive data normally.

In the embodiment of the present invention, the manner of adjusting the resource allocation information is different for different triggering conditions, and is specifically described below.

Preferably, the step of generating resource configuration information corresponding to a plurality of time periods according to the first information reported by the terminal includes:

if the preset triggering condition is the first triggering condition, expanding a resource pool reported by the terminal, and/or adjusting the bitmap, and/or reducing a second preset power threshold corresponding to a service with a priority lower than that of the first service, and/or reducing a channel duty ratio threshold corresponding to a service with a priority lower than that of the first service;

if the preset triggering condition is the second triggering condition, expanding a resource pool reported by the terminal, and/or adjusting the bitmap, and/or reducing a second preset power threshold corresponding to a service with a priority lower than that of the first service, and/or reducing a channel duty ratio threshold corresponding to a service with a priority lower than that of the first service;

and if the preset triggering condition is the third triggering condition, reducing a first preset power threshold corresponding to the service with the priority lower than the first service.

If the preset trigger condition is the first trigger condition or the second trigger condition, adjusting the bitmap may be adjusting more bits in the bitmap to 1, so as to allocate more subframes for the first service.

In the embodiment of the invention, if a plurality of terminals report the first information in the same time period, the configuration principle for generating the resource configuration information corresponding to the time period is as follows: larger resources can be configured for all reported resource pools; and/or, adjusting a bitmap corresponding to the resource pool, and/or, reducing a channel duty ratio threshold corresponding to a service with a priority lower than that of the first service; and/or, lowering a first power threshold corresponding to a service with a priority lower than that of the first service; and/or, lowering the second power threshold corresponding to the service with the priority lower than the first service.

However, when the current resources are limited and all reported resource pools cannot be enlarged at the same time, there are various ways to generate the resource configuration information corresponding to the time period, which is illustrated below.

As a first alternative embodiment: and carrying out resource configuration adjustment according to the priority of the triggering condition.

Specifically, the priorities of the resource configuration information adjustment of the first trigger condition, the second trigger condition and the third trigger condition are sequentially arranged from high to low, and the step of generating the resource configuration information corresponding to a plurality of time periods according to the first information reported by the terminal includes:

That is, the priority of the trigger condition is: the first trigger condition > the second trigger condition > the third trigger condition. The network side equipment receives first information comprising different preset trigger conditions, the problem of high priority is solved preferentially, and the problem of low priority is solved after the problem of high priority is solved.

As a second alternative embodiment: and carrying out resource configuration adjustment according to the first information reported by the terminals corresponding to different resource pools in the same resource configuration information.

Specifically, the step of generating resource configuration information corresponding to a plurality of time periods includes:

if the number of the terminals reporting the first information at the same time is at least two, and the resource pools reported by each terminal are contained in different resource pools in the first resource allocation information, acquiring a second service corresponding to each resource pool in the different resource pools, wherein the second service is the service with the highest priority in the first service reported by the terminal corresponding to the resource pool; the first resource configuration information is preconfigured resource configuration information, or is carried by an SIB or RRC reconfiguration message broadcasted by the network side equipment and corresponds to a period matched with the same time;

And sequentially adjusting the resource configuration information of all the reported resource pools according to the sequence from high priority to low priority of the second service corresponding to each resource pool.

Specifically, the resource pools reported by the terminal reporting the first information at the same time are different resource pools in the same resource configuration information (i.e. the first resource configuration information), the first service (i.e. the second service) with the highest priority in each reported resource pool is obtained, and the requirement of the second service with the highest priority is preferably met according to the order of the priority of the second service corresponding to each resource pool from high to low.

For example, UE H, UE I, UE J and UE K all report first information to the network side device at the same time, and among the first information reported by UE H, UE H executes the first service in the resource pool RP 1; in the first information reported by the UE I, the UE I executes a first service in a resource pool RP 1; in the first information reported by the UE J, the UE J executes a first service in a resource pool RP 2; in the first information reported by the UE K, the UE K executes a first service in a resource pool RP 2.

And respectively acquiring second services corresponding to RP1 and RP 2. If the priority of the first service reported by the UE H is higher than that of the first service reported by the UE I, the second service corresponding to the RP1 is the first service reported by the UE H; if the priority of the first service reported by the UE J is higher than that of the first service reported by the UE K, the second service corresponding to the RP2 is the first service reported by the UE J.

Comparing the priority of the second service corresponding to RP1 (the first service reported by UE H) with the priority of the second service corresponding to RP2 (the first service reported by UE J), if the priority of the second service corresponding to RP1 is higher, determining that the service with the current priority is the second service corresponding to RP1, preferentially adjusting the resource configuration information of RP1, and then adjusting the resource configuration information of RP 2.

Preferably, the step of sequentially adjusting the resource configuration information of all reported resource pools includes:

determining the service of the current priority according to the priority of the second service corresponding to each resource pool;

if the total resources of the current configurable system at least can meet the resource expansion requirement corresponding to the service of the current priority, expanding a resource pool corresponding to the service of the current priority, or adjusting a bitmap associated with the resource pool corresponding to the service of the current priority; otherwise, reducing a first preset power threshold corresponding to the service with the priority lower than the current priority; and/or, reducing a second preset power threshold corresponding to the service with the lower priority than the current priority; and/or, reducing the channel duty ratio threshold corresponding to the service with the priority lower than the current priority.

For example, UE a, UE B, and UE C are taken as examples. At a time point t1 (yy-mm-dd-hh-mm-ss), a subframe n1, where the priority of the service of the geographic location1 is k1 and the selected resource pool is RP1, the terminal calculates a channel occupation ratio accumulation sum of all services with priority less than or equal to k1 in the [ n1-a, n1+ b ] subframe, and if the channel occupation ratio accumulation sum is greater than or equal to a channel occupation ratio threshold cr_limit corresponding to the priority of k1 (cr_limit may be located in a resource configuration message broadcasted by a network side device, an RRC reconfiguration message sent by the network side device, or a resource configuration message preconfigured by the terminal or the network side device), the UE a generates first information, where the first information includes: t1, location1, resource pool RP1, priority k1, channel duty accumulation sum, and cr_limit, and report the first information to the network device when UE a enters the connected state next time.

At a time point t1 (yy-mm-dd-hh-mm-ss), a subframe n1, a priority of a service at a geographic location of location1 is kk1, and a selected resource pool is RP1, a channel occupation ratio accumulation sum of all services with priorities less than or equal to kk1 in the [ n1-a, n1+b ] subframe is calculated, and if the channel occupation ratio accumulation sum is greater than or equal to cr_limit corresponding to kk1 priority, the UE B generates first information, where the first information includes: t1, location1, resource pool RP1, priority kk1, channel duty accumulation sum, and cr_limit, and report the first information to the base station when UE B enters the connected state next time.

At a time point t1 (yy-mm-dd-hh-mm-ss), a subframe n1, a service priority of location2 at a geographic location is k2, and a selected resource pool is RP2, a channel occupancy sum of all services with priorities less than or equal to k2 in an [ n1-a, n1+ b ] subframe is calculated, and if cr_limit corresponding to the priority of k2 is greater than or equal to, the UE C generates first information, where the first information includes: t1, location2, resource pool RP2, priority k2, channel duty accumulation sum, and cr_limit, and report the first information to the base station when UE C enters the connected state next time.

The resource pools reported by UE a, UE B and UE C are all included in the same piece of resource configuration information (i.e., the first resource configuration information may be preconfigured resource configuration information, or carried by a broadcasted system information block or RRC reconfiguration message and corresponds to a period of time matching the same time t 1).

If the priority k2 of the service (i.e., the first service of UE C) on the resource pool RP2 corresponding to the location2 reported by UE C is higher than the priority k1 of the service (i.e., the first service of UE a) on the resource pool RP1 corresponding to the location1 of UE a and also higher than the priority kk1 of the service (i.e., the first service of UE B) on the resource pool RP1 corresponding to the location1 of UE B, the service of the current priority is the service on the resource pool RP2 reported by UE C, and the resource configuration information of the resource pool RP2 is adjusted.

If the total resources of the system which can be configured at present at least can meet the expansion requirement of the resource pool RP2 corresponding to the k2 priority, configuring larger resources for the resource pool RP2, or adjusting a bitmap associated with the resource pool RP2 reported by the UE C, and distributing more subframes for the resource pool RP 2. If the current configurable total system resources can not meet the expansion requirement of the resource pool RP2 corresponding to the k2 priority, the first preset power threshold corresponding to the k1 and kk1 priorities can be reduced; and/or, reducing a second preset power threshold corresponding to the priorities of k1 and kk 1; and/or reducing the channel duty ratio threshold CR_limit corresponding to the priorities of k1 and kk1 to ensure the transceiving of the service with the current priority (namely the service with the priority of k 2).

As a third alternative embodiment: and carrying out resource configuration adjustment corresponding to different services according to the first information reported by the terminals corresponding to the same resource pool in the same resource configuration information.

Specifically, the step of generating resource configuration information corresponding to a plurality of time periods according to the first information reported by the terminal includes:

if the number of the terminals reporting the first information at the same time is at least two, the resource pools reported by each terminal are the same and are contained in the second resource allocation information, a third service corresponding to each sub-resource in the resource pools is obtained, and the third service is the service with the highest priority in the first service reported by the terminal corresponding to the sub-resource; the second resource configuration information is preconfigured resource configuration information, or is carried by an SIB or RRC reconfiguration message broadcasted by the network side equipment and corresponds to a period matched with the same time;

And sequentially adjusting resource configuration information corresponding to the services with different priorities and reported by all the terminals according to the sequence from high priority to low priority of the third service corresponding to each sub-resource.

Wherein, the sub-resource may be a sub-channel in a resource pool. One sub-resource in the reported resource pool can correspond to a first service reported by a plurality of terminals, and the service with the highest priority in the first service reported by the plurality of terminals can be obtained and used as a third service corresponding to the sub-resource.

Preferably, the step of sequentially adjusting resource configuration information corresponding to the services with different priorities reported by the terminal includes:

determining the service of the current priority according to the priority of the second service corresponding to each sub-resource;

reducing a first preset power threshold corresponding to a service with a lower priority than the current priority; and/or, reducing a second preset power threshold corresponding to the service with the lower priority than the current priority; and/or, reducing the channel duty ratio threshold corresponding to the service with the priority lower than the current priority.

Taking UE a and UE B as an example, the network side device receives first information reported by UE a and UE B at time point t1, where the reported resource pools are RP1 and the reported sub-resources are S1 in RP1, selects the higher one of the k1 priority and the kk1 priority as the congestion service priority of sub-resource S1 in the current resource pool RP1, that is, as the service of the current priority, and considers that UE a and UE B use the same sub-resource in the resource pool RP1 at time point t1, configures a lower first preset power threshold, a lower second preset power threshold and/or a lower channel duty ratio threshold for the lower one of the k1 priority and the kk1 priority to ensure the transceiving of the service of the current priority.
