Description

Resource allocation method, network side equipment and terminal

Technical Field

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

Background

For a long Term Evolution (L ong Term Evolution, L TE) -Vehicle-to-outside information exchange (Vehicle toX, V2X) service, a User Equipment (UE, also called a terminal) has two Resource configuration methods, a Resource configuration method based on scheduling and an automatic Resource configuration selection (automatic Resource selection) method, for a UE using the automatic Resource configuration method, Resource configuration is in units of Resource pools, one Resource pool includes a plurality of sub-channels (subchannels), and one subchannel includes a plurality of Physical Resource Blocks (PRBs).

1) For terminals in an idle state (RRC _ ID L E) or a CONNECTED state (RRC _ CONNECTED) within a large network coverage area, a base station may broadcast a System Information Block (SIB) 21 to broadcast a series of resource pool configuration Information for all terminals;

2) for a terminal in the RRC _ CONNECTED state within the coverage of the large network, the base station may include Resource pool configuration information in a Radio Resource Control (RRC) reconfiguration message;

3) and a series of resource pool configuration information is preconfigured for the terminal through a base station or terminal preconfiguration form.

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

(1) if the resource configuration information in the SIB21, the RRC reconfiguration message, or the pre-configuration message includes a zone-configuration message (zone-configuration), the terminal selects a unique resource pool according to its own geographic area for control and data transmission using a one-to-one mapping relationship between the resource pools and the geographic locations (zones) in the configuration message.

(2) If the geographic area configuration message (zone-config) does not exist in the resource configuration message, the UE randomly selects a first resource pool from the configured resource pool list for sending and receiving.

After the resource pool is clarified, the UE may select a corresponding subchannel based on a random selection or partial sensing (partial sensing) manner; in the physical layer sending process, the terminal selects subchannels with Reference Signal Receiving Power (RSRP) less than or equal to a threshold value and direct mode reference Signal Strength Indication (S-RSSI) smaller as candidate sub-channels for sending and Receiving data.

However, in the existing standard, after a resource pool is defined, time factors are not considered in a subchannel, PRB resource sensing, and scheduling scheme of each terminal in the resource pool, and in an actual environment, the number of vehicles on different dates and different periods changes greatly, for example: the road section A is busy at the early peak of 7:30-9:30 and the late peak of 5:30-7:30 in the working day, and is idle in the rest period and the rest day of the working day. By adopting the existing resource allocation method, the channel occupancy in some resource pools may be high in a peak period, the channel occupancy in the resource pools is low in a peak period or a low-peak period, and the channel occupancy in some resource pools may be high in a certain period and the channel occupancy in other resource pools is low in a certain period, 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 clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

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

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

step 12: and transmitting the resource configuration information corresponding to the time interval to the terminal in each time interval.

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 non-congestion condition can be adjusted, thereby ensuring that all terminals can normally receive and transmit data.

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

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

In the above embodiment, the multiple time periods may be multiple time periods in a designated cycle, and the designated cycle may be set according to actual requirements, for example: a plurality of time intervals in one day, a plurality of time intervals in a week, it is more nimble convenient.

In the embodiment of the present invention, there are various preset trigger conditions, which are exemplified below.

That is to say, the reason for triggering the terminal to report the first information is the first trigger condition, the second trigger condition, or the 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 terminal reports the first information to the network side device. If the terminal is in a connection state currently and has available resources, reporting first information to network side equipment immediately; and if the terminal is not in the connection state currently, reporting the first information to the network side equipment when the terminal enters the connection state next time.

For the first trigger condition, for example, at time point t1(yy-mm-dd-hh-mm-ss), in subframe n1, the priority of the traffic at the geographic location1 is k1, and the selected resource pool is RP1, the terminal calculates the channel-to-channel ratio cumulative sum of all the traffic with the priority less than or equal to k1 in [ n1-a, n1+ b ] subframe, and if the sum is greater than CR _ limit corresponding to the priority of k1 (CR _ limit may be located in a resource configuration message broadcast by the 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 ratio cumulative sum, and CR _ limit, determining that a first trigger condition is satisfied, and reporting the first information to the network side device, where the first information further includes: the reason for triggering the UE a to report the first information is as follows: a first trigger condition.

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

For the third trigger condition, for example, when the UE E selects a resource from the resource pool RP5 at time point t5(yy-mm-dd-hh-mm-ss), the subframe n5 is located at the geographic location5, and after excluding the subchannels whose RSRP is greater than the first preset power threshold, the number of remaining subchannels is less than the preset threshold, that is, there are fewer candidate resources to select, which indicates that the UE E may be due to traffic congestion on the RP5 or may be due to that the first preset power threshold is not reasonable, the UE E generates the first information, where the first information includes: t5, location5, and resource pool RP5, determining that the third trigger condition is satisfied, and reporting the first information to the network side device, where the first information further includes: the reason for triggering the UE E to report the first information is as follows: a third trigger condition.

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

Still taking UE E as an example, if after excluding the sub-channels with RSRP greater than the first preset power threshold, the ratio of the remaining sub-channels to RP5 is smaller than a preset ratio threshold (for example, 20%), the third trigger condition is met, and the first information is reported to the network side device.

Wherein the reporting of the first information at the time point comprises: and 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 a geographical position of the terminal at the time point.

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

In the embodiment of the present invention, the resource configuration information corresponding to a plurality of time periods in a specific period may 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 multiple time periods in a day according to all first information reported by multiple terminals in a week or a month, such as: and aiming at a geographical position, allocating larger resources for the resource pool corresponding to the geographical position at the early peak of the working day of 7:00-9:00 and the late peak of the working day of 17:00-19: 00.

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 geographical location is not congested at ordinary times, but in 13:00-13:30 today, a plurality of terminals continuously report the resource pool, which indicates that larger resources are configured for the resource pool corresponding to the geographical location in the next time period (such as 13:30-14:00) possibly due to traffic congestion occurring at the geographical location.

In some preferred embodiments of the present invention, step 11 is preceded by:

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

mapping relation between initially configured resource pool and geographic position;

the size of the resource pool initially configured;

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

configuring a first preset power threshold value for selecting resources for services with different priorities;

a second preset power threshold value used for measuring the channel occupation condition;

and mapping relation between the priority of the service and the channel 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 bit in the bitmap is 1, the subframe corresponding to the bit is used for transmitting the service.

The first preset power threshold is used for the terminal to select the resource according to the perceived RSRP of the current resource. If the RSRP of the current resource is larger than a first preset power threshold value, the current resource is not available; and if the RSRP of the current resource is less than or equal to the first preset power threshold, indicating that the current resource is available.

The second preset power threshold is used for the terminal to determine whether the current resource is occupied or not, whether the current priority service can be carried, and may be an RSRP threshold for calculating a Channel Busy Ratio (CBR). If the current resource is full, the resource of the service with lower priority than the current priority can be sacrificed to ensure that the service with high priority (i.e. the service with current priority) has enough available resource.

For example, the initial geographic location M corresponds to the resource pool M, and the UE selects a resource on the resource pool M for transceiving current service 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; then, detecting S-RSSI of sub-channels with RSRP less than or equal to a first preset power threshold value, and selecting the sub-channels with smaller S-RSSI (the sub-channels with smaller S-RSSI have lower interference) as resources used by the UE for transmitting and receiving; verifying whether the load of the selected resource is too high, and calculating the channel occupation ratio of the selected resource according to a second preset power threshold, namely calculating the proportion of sub-channels of which the RSRP exceeds the second preset power threshold within a certain time; if the calculated ratio value is greater than the channel occupation ratio threshold corresponding to the current service, it indicates that the selected resource load is too high, the UE needs to report the first information again, and the network side device needs to perform resource allocation again.

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

The original resource configuration information may be carried by an SIB broadcasted by the network side device to the terminal, may also be carried by an RRC reconfiguration message sent by the network side device to the terminal, and may also be original resource configuration information preconfigured by the network side device for the terminal.

Of course, in some other preferred embodiments of the present invention, the terminal may also pre-configure the original resource configuration information, and the present invention is not limited thereto.

In this embodiment of the present invention, the step of generating resource configuration information corresponding to multiple time intervals includes at least one of:

adjusting the size of the 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;

In particular, resizing the resource pool may be to expand or contract the resource pool.

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

Adjusting the bitmap corresponding to the resource pool may be to adjust more bits in the bitmap to 1, so as to allocate more subframes for the first service, which is equivalent to enlarging the resource pool; or, more bits in the bitmap are adjusted to 0, so that fewer subframes are allocated to 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 by increasing the first preset power threshold, sub-channels with RSRP larger than the first preset power threshold are reduced, namely, excluded sub-channels are reduced, and candidate sub-channels are increased; the method also comprises the steps of reducing a first preset power threshold corresponding to the first service, increasing the excluded sub-channels and reducing the candidate sub-channels.

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 with RSRP exceeding 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 condition that the first information needs to be reported again.

Adjusting the channel occupation ratio threshold corresponding to the first service comprises increasing the channel occupation ratio threshold corresponding to the first service, and reducing the situation that the first information needs to be reported again by increasing the channel occupation ratio threshold; and reducing the channel occupation ratio threshold corresponding to the first service, and increasing the situations that the first information needs to be reported again.

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 an effective theoretical basis for calculating resource pool configuration information, and the method comprises the following steps: the size of the resource pool, the mapping relation between the resource pool and the geographic position, the mapping relation between the resource pool and the time period, the RSRP threshold value of the CBR and other parameters.

In the embodiment of the invention, the network side equipment can generate the resource configuration information corresponding to the actual situation through one or more ways according to the actual situation (namely, the number of vehicles in different geographical positions, different dates and different time periods changes and the like), so that the situations that the channel occupation ratio in some resource pools is high and the channel occupation ratio in other resource pools is low can be avoided, the problem of resource congestion can be solved, and the resources under the non-congestion situation can be adjusted, so that all terminals can normally receive and transmit data.

In the embodiment of the present invention, the manner of adjusting the resource configuration information is also different for different trigger conditions, which is described in detail 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, enlarging a resource pool reported by the terminal, and/or adjusting the bitmap, and/or reducing a second preset power threshold value corresponding to the service with the priority lower than the first service, and/or reducing a channel occupation ratio threshold value corresponding to the service with the priority lower than the first service;

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

and if the preset trigger condition is the third trigger condition, reducing a first preset power threshold value 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 to adjust more bits in the bitmap to 1, so as to allocate more subframes for the first service.

In the embodiment of the present invention, if a plurality of terminals report first information at the same time interval, a configuration principle of generating resource configuration information corresponding to the time interval 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 occupation ratio threshold value of the service with the priority lower than that of the first service; and/or, reducing a first power threshold corresponding to a service with a priority lower than that of the first service; and/or reducing the priority lower than a second power threshold corresponding to the first service.

However, when the current resources are limited and all reported resource pools cannot be expanded simultaneously, there are a variety of ways to generate resource configuration information corresponding to a time interval, which will be exemplified below.

As a first alternative embodiment: and according to the priority of the trigger condition, adjusting the resource configuration.

Specifically, the priorities of the adjusted resource allocation information 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 allocation 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: first trigger condition > second trigger condition > 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 adjusting the resource allocation according to the first information reported by the terminals corresponding to different resource pools in the same resource allocation information.

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

if the number of the terminals reporting the first information at the same time is at least two, and the resource pool reported by each terminal is contained in different resource pools in the first resource configuration 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 services reported by the terminals corresponding to the resource pools; the first resource configuration information is preconfigured resource configuration information, or is carried by an SIB or RRC reconfiguration message broadcast by the network side device and corresponds to a time period matching the same time;

and sequentially adjusting the resource configuration information of all the reported resource pools according to the sequence of the priorities of the second services corresponding to the resource pools from high to low.

Specifically, resource pools reported by terminals reporting first information at the same time are different resource pools in the same resource configuration information (i.e., the first resource configuration information), a first service (i.e., a second service) with the highest priority in each reported resource pool is obtained, and the requirements of the second service with the highest priority are preferentially met according to the sequence of the priorities of the second services corresponding to each resource pool from high to low.

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

And respectively acquiring second services corresponding to the RP1 and the 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; and 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.

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

Preferably, the step of sequentially adjusting the resource configuration information of all the 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 system resources which are currently configurable 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 priority lower than the current priority; and/or reducing a channel occupation ratio threshold value 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), in a subframe n1, the priority of the traffic at the geographic location1 is k1, and the selected resource pool is RP1, the terminal calculates the channel occupancy cumulative sum of all the traffic with the priority less than or equal to k1 in [ n1-a, n1+ b ] subframe, and if the channel occupancy sum is greater than or equal to the channel occupancy threshold CR _ limit corresponding to the priority of k1 (CR _ limit may be located in a resource configuration message broadcast by the 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 ratio cumulative sum, and CR _ limit, and report the first information to the network side device when UE a enters the connected state next time.

At a time point t1(yy-mm-dd-hh-mm-ss), in a subframe n1, the priority of the traffic at the geographical location1 is kk1, and the selected resource pool is RP1, calculating the cumulative sum of the channel occupancy ratios of all the traffic with the priority less than or equal to kk1 in the [ n1-a, n1+ B ] subframe, and if the sum is greater than or equal to CR _ limit corresponding to the priority of kk1, generating first information by the UE B, wherein the first information includes: t1, location1, resource pool RP1, priority kk1, channel ratio cumulative sum, and CR _ limit, and reports the first information to the base station when UE B enters a connected state next time.

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

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

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

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

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

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 included in the second resource configuration information, acquiring a third service corresponding to each sub-resource in the resource pools, wherein the third service is the service with the highest priority in the first services reported by the terminals corresponding to the sub-resources; the second resource configuration information is preconfigured resource configuration information, or is carried by an SIB or RRC reconfiguration message broadcast by the network side device and corresponds to a time period matching the same time;

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

The sub-resource may be a sub-channel in a resource pool. One sub-resource in the reported resource pool may correspond to the first services reported by the multiple terminals, and a service with the highest priority in the first services reported by the multiple terminals may be obtained as a third service corresponding to the sub-resource.

Preferably, the step of sequentially adjusting resource configuration information corresponding to services with different priorities reported by all the terminals 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 priority lower than the current priority; and/or reducing a second preset power threshold corresponding to the service with the priority lower than the current priority; and/or reducing a channel occupation ratio threshold value corresponding to the service with the priority lower than the current priority.

Still taking UE a and UE B as an example, the network side device receives, at time point t1, the first information respectively reported by UE a and UE B, where the reported resource pools are all RP1, and the reported sub-resources are also the same and are all S1 in RP1, and selects the higher one of the k1 priority and the kk1 priority as the congestion traffic priority of the sub-resource S1 in the current resource pool RP1, that is, as the traffic of the current priority, in consideration of that UE a and UE B use the same sub-resource in the resource pool RP1 at time point t1, a lower first preset power threshold, a lower second preset power threshold, and/or a lower channel occupation threshold are configured for the lower one of the k1 priority and the kk1 priority, so as to ensure the transceiving of the traffic of the current priority.
