Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The first embodiment is as follows:

in order to solve the problem that in the existing method of selecting a transmission resource pool according to geographical position indication information and a CBR threshold, because the transmission resource pool is selected only according to the geographical position indication information and the CBR threshold, the size of a to-be-transmitted data packet may not match the transmission resource pool, for example, the size of the to-be-transmitted data packet is greater than the total resource amount of the transmission resource pool, so that the matching degree between the size of the to-be-transmitted data packet and the selected transmission resource pool is low, an embodiment of the present invention provides a resource pool selection method, which, as shown in fig. 1, includes:

s101, receiving resource pool configuration information of each resource pool sent by a base station, wherein the resource pool configuration information comprises geographical position indication information, and the resource pool configuration information further comprises a number threshold value allowed to be sent, and/or data packet size information and a CBR (Channel Busy Ratio) threshold value.

In this embodiment, the terminal may receive resource pool configuration information of each resource pool sent by the base station, where the resource pool configuration information of any resource pool includes geographic position indication information, and the resource pool configuration information of any resource pool further includes a threshold value of the number allowed to be sent, and/or size information of a data packet and a CBR threshold value of a channel occupancy ratio. The geographical position indication information may include longitude, latitude, and other information used for indicating the geographical position. The threshold value of the number of allowed data packets to be transmitted is the threshold value of the number of data packets allowed to be transmitted by the resource pool, and when the quotient obtained by dividing the total amount of the available resources of the resource pool by the size of the data packets to be transmitted is greater than the threshold value of the number of allowed data packets to be transmitted configured for the resource pool, the data packets to be transmitted are matched with the resource pool, and the data packets to be transmitted can be transmitted by using the resources in the resource pool. The packet size information includes the size of the packet configured for the resource pool. The CBR threshold includes a CBR threshold configured for the resource pool, and when the current CBR value of the resource pool is smaller than the CBR threshold, the resource in the resource pool is selected to send the data packet, where CBR = occupied resource amount/total resource amount.

In this embodiment, the resource pool configuration information may include geographic location indication information and a threshold value of the number of allowed transmissions. The resource pool configuration information may also include geographical location indication information, packet size information, and CBR threshold values. The resource pool configuration information may further include geographical location indication information, a number allowed to be sent threshold, packet size information, and a CBR threshold.

In this embodiment, the terminal may receive Resource pool configuration information of each Resource pool sent by the base station through a system broadcast message and/or a dedicated signaling of a Radio Resource Control (RRC) protocol. That is, the terminal may receive the resource pool configuration information of each resource pool sent by the base station through the system broadcast message; the terminal can also receive resource pool configuration information of each resource pool sent by the base station through the RRC dedicated signaling; the terminal can also receive resource pool configuration information of each resource pool sent by the base station through a system broadcast message and RRC dedicated signaling. The terminal can also receive resource pool configuration information of each resource pool sent by the base station through the system broadcast message, and after receiving the resource pool configuration information of each resource pool sent by the base station through the system broadcast message, the terminal can also receive updated resource pool configuration information of each resource pool sent by the base station through an RRC (radio resource control) dedicated signaling.

S102, selecting at least one resource pool from the resource pools as a sending resource pool according to the size of a data packet to be sent, the current state information of the resource pools, the current position information and the resource pool configuration information of the resource pools.

In this embodiment, the resource pool configuration information of each resource pool sent by the base station is received, and when the base station needs to send a data packet, it needs to select a sending resource pool from each resource pool to send data. The mode for selecting the data packet transmission is as follows: and selecting at least one resource pool from the resource pools as a sending resource pool according to the size of the data packet to be sent, the current state information and the current position information of the resource pools and the resource pool configuration information of the resource pools, wherein one or more sending resource pools can be selected. And the current position information is the current position information of the terminal. The current state information of the resource pool can be acquired by the terminal through sensing, so that the current state information of the resource pool can be judged through sensing before the resource pool is selected and sent from the resource pools according to the size of a data packet to be sent, the current state information of the resource pool, the current position information and the resource pool configuration information of the resource pools.

The type of the data packet to be sent may be any type of data packet to be sent, for example, the data packet may be generated by a semi-static service, or may be generated by a dynamic service. The target transmission object of the data packet to be transmitted may be any object, for example, the data packet to be transmitted may be transmitted to the base station, or may be transmitted to the terminal.

The size of the data packet to be sent may include the size of the data packet to be sent, and the size of the data packet to be sent may also include a strength number of the data packet to be sent, which is determined according to the size of the data packet to be sent.

When the size of the data packet to be sent includes the strength number of the data packet to be sent, before selecting a sending resource pool from the resource pools in S102, the terminal should also receive strength configuration information of the data packet sent by the base station, where the terminal may receive the strength configuration information of the data packet sent by the base station through a system broadcast message and/or an RRC dedicated signaling. That is, the terminal can receive the data packet strength configuration information sent by the base station through the system broadcast message; the terminal can also receive the data packet strength configuration information sent by the base station through the RRC special signaling; the terminal can also receive the data packet strength configuration information sent by the base station through the system broadcast message and the RRC dedicated signaling. The terminal can also receive the data packet strength configuration information sent by the base station through the system broadcast message, and after receiving the data packet strength configuration information sent by the base station through the system broadcast message, the terminal can also receive the updated data packet strength configuration information sent by the base station through the RRC dedicated signaling. In some embodiments, the terminal may receive the resource pool configuration information and the data packet strength configuration information of each resource pool together, and of course, the terminal may also receive the resource pool configuration information and the data packet strength configuration information of each resource pool respectively. It should be noted that the terminal may also receive the packet strength configuration information in other manners.

The data packet strength configuration information includes the size range of each data packet and the strength number corresponding to the size range of each data packet. The packet strength configuration information can be seen in table 1 below:

TABLE 1

The force number can be letters and/or numbers, the force number and the size range of the data packet are in one-to-one correspondence, and n1, n2, n3, n4, n5 and n6 are integers which are more than or equal to 0. In order to ensure that the size range of the data packet matched with the data packet to be sent is unique, the size ranges of the data packets in the data packet strength configuration information are not overlapped. In some embodiments, in the packet strength configuration information, the difference values of the packet size ranges may be the same, i.e., (n 2-n 1) = (n 4-n 3) = (n 6-n 5), for example, please refer to table 2, and if the difference values of the packet size ranges are all 500Bytes, the packet strength configuration information refers to table 2.

TABLE 2

Dynamics numbering	Packet size range
		0	0Bytes-500Bytes
1	501Bytes-1000Bytes
		2	1001Bytes-1500Bytes
……	……

In some embodiments, the packet size configuration information may also be different from each other in the size range of each packet, for example, please refer to table 3, where table 3 is an example of the packet strength configuration information:

TABLE 3

Dynamics numbering	Packet size range
		0	0Bytes-5000Bytes
1	5001Bytes-15000Bytes
		2	15001Bytes-45000Bytes
……	……

In some embodiments, to ensure that the packets to be sent with different sizes can be matched with a certain packet size range in the packet strength configuration information, the packet size range in the packet strength configuration information may cover all the sizes of the packets to be sent that may exist. It should be noted that the packet strength configuration information includes, but is not limited to, the above examples.

After the data packet strength configuration information is received, when the data packet needs to be sent, the terminal can find a data packet size range matched with the size of the data packet to be sent from the data packet strength configuration information according to the size of the data packet to be sent, and then, a strength number corresponding to the matched data packet size range is used as a data packet strength number to be sent. For example, assuming that the strength configuration information of the data packet to be sent is shown in table 2, and the size of the data packet to be sent is 560Btytes, according to table 2, the size range of the data packet matching the size of the data packet to be sent is 501Bytes-1000bytes,501bytes-1000Bytes, and the corresponding strength number is 1, the size of the data packet to be sent includes the strength number of the data packet to be sent, and the number of the data to be sent is 1.

And when the size information of the data packet to be sent comprises the strength number of the data packet to be sent, the size information of the data packet in the resource pool configuration information comprises the strength number of the data packet.

And when the size information of the data packet to be sent comprises the size of the data packet to be sent, the size information of the data packet in the resource pool configuration information comprises the size of the data packet.

In this embodiment, according to the size of the data packet to be sent, the current state information of the resource pool, the current location information, and the resource pool configuration information of each resource pool, selecting a sending resource pool from each resource pool may be: and selecting at least one resource pool matched with the current position information from the resource pools as a target resource pool according to the current position information and the geographical position indication information in the resource pool configuration information of each resource pool, and then selecting at least one resource pool from the target resource pool as a sending resource pool according to the size of a data packet to be sent, the current state information of the resource pool and the resource pool configuration information of the target resource pool. It should be understood that the geographical location indication information in the resource pool configuration information of the target resource pool matches the current geographical indication information of the terminal. According to the size of the data packet to be sent, the current state information of the resource pools, the current position information and the resource pool configuration information of each resource pool, selecting a sending resource pool from each resource pool may also be: and selecting at least one matched resource pool from the resource pools according to the size of the data packet to be transmitted, the current state information of the resource pools and the resource pool configuration information of the target resource pool, and selecting at least one resource pool matched with the current position information from the matched resource pools as a transmission resource pool.

The resource pool configuration information is different, and the mode of selecting the resource pool to be transmitted from the target resource pool according to the size of the data packet to be transmitted, the current state information of the resource pool and the resource pool configuration information of the target resource pool is also different.

When the resource pool configuration information includes the data packet size information and the CBR threshold, selecting a transmission resource pool from the target resource pool according to the size of the data packet to be transmitted, the current state information of the resource pool, and the resource pool configuration information of the target resource pool may be: according to the size of a data packet to be sent, a resource pool CBR measured value, data packet size information of a target resource pool and a CBR threshold value, at least one resource pool which is matched with the size of the data packet to be sent and the CBR measured value of the resource pool and the CBR threshold value is selected from the target resource pool as a resource pool which can be sent, wherein the current state information of the resource pool comprises the CBR measured value of the resource pool, and the CBR measured value of the resource pool is generated by the current occupied resource amount of the resource pool and the total resource amount of the resource pool (namely the CBR measured value = the current occupied resource amount of the resource pool/the total resource amount of the resource pool). For the current available resource amount of the resource pool, the terminal can judge the current occupied resource amount of the resource pool through sensing the sending, wherein the terminal can judge the average occupied resource amount of the resource pool in the previous preset time period through sensing the sending to determine the current available resource amount of the resource pool, for example, the terminal can judge the average occupied resource amount of the resource pool in the previous 1 second through sensing the sending to determine the current occupied resource amount of the resource pool; the terminal can also determine the current occupied resource amount of the resource pool by sensing the occupied resource amount of the resource pool at the current moment. Of course, the terminal may also determine the amount of resources currently occupied by the resource pool in other manners. For the total resource amount of the resource pool, generally, the resource pool configuration information includes the total resource amount of the resource pool, so that the terminal can judge the total resource amount of the resource pool through the resource pool configuration information; or, the terminal may determine the total resource amount of the resource pool by sensing, and certainly, the terminal may also determine the total resource amount of the resource pool by other manners.

When the size of the data packet to be sent includes the size of the data packet to be sent, and the size information of the data packet includes the size range of the data packet, the matching between the size of the data packet to be sent and the size information of the data packet to be sent can be that the size of the data packet to be sent belongs to the size range of the data packet, for example, if the size of the data packet to be sent is 1500Bytes, the size range of the data packet of the resource pool a is 0Bytes-10000Bytes, and the size range of the data packet of the resource pool B is 0Bytes-500Bytes, the size of the data packet to be sent is matched with the resource pool a and is not matched with the resource pool B; when the size of the data packet to be sent includes the strength number of the data packet to be sent, and the size information of the data packet includes the strength number, the matching between the size of the data packet to be sent and the size information of the data packet may be that one of the strength numbers in the size information of the data packet is consistent with the data number to be sent, for example, if the strength numbers included in the size information of the data packet in the resource pool C are 0, 1, and 2, the strength numbers included in the size information of the data packet in the resource pool D are 0 and 1, and the strength number of the data packet to be sent is 2, the size of the data packet to be sent is matched with the resource pool C, and is not matched with the resource pool D.

The resource pool with the resource pool CBR measured value matched with the CBR threshold value is that the CBR measured value of the resource pool is smaller than the CBR threshold value of the resource pool. For example, if the CBR measurement value of the resource pool E is 50% and the CBR threshold value in the resource pool configuration information of the resource pool E is 60%, the CBR measurement value of the resource pool E is matched with the CBR threshold value; if the CBR measurement value of the resource pool F is 80% and the CBR threshold value in the resource pool configuration information of the resource pool F is 40%, the CBR measurement value of the resource pool F is not matched with the CBR threshold value.

The step of selecting, according to the size of the data packet to be sent, the CBR measurement value of the resource pool, and the data packet size information and the CBR threshold of the target resource pool, a resource pool from the target resource pool whose size of the data packet to be sent matches the data packet size information, and whose CBR measurement value and CBR threshold match, as the transmittable resource pool, may be: and selecting at least one matched resource pool from the target resource pools as a first resource pool according to the size of the data packet to be sent and the size information of the data packet, and selecting at least one resource pool with a CBR (measure-per-round ratio) value larger than a CBR threshold value from the first resource pool as a sending resource pool, wherein the current state information of the resource pools comprises the CBR measure value of the first resource pool, and the CBR measure value is generated according to the current occupied resource amount of the resource pools and the total resource amount of the resource pools. Or selecting at least one resource pool with the CBR measurement value smaller than the CBR threshold value from the target resource pools, and selecting at least one matched resource pool from the selected resource pools as a sending resource pool according to the size of the data packet to be sent and the size information of the data packet.

When the resource pool configuration information includes the data packet size information, the CBR threshold, and the mapping relationship between the data packet size information and the CBR threshold, selecting a sending resource pool from the target resource pool according to the size of the data packet to be sent, the current state information of the resource pool, and the resource pool configuration information of the target resource pool may be: according to the mapping relation between the size information of the data packets of the target resource pool and the CBR threshold value and the size of the data packets to be sent, a first target CBR threshold value matched with the size of the data packets to be sent is confirmed, a resource pool with a CBR measured value smaller than the first target CBR threshold value is selected from the target resource pool to serve as a sending resource pool, wherein the current state information of the resource pool comprises the CBR measured value of the target resource pool, and the CBR measured value is generated according to the current occupied resource amount of the resource pool and the total resource amount of the resource pool. The mapping relationship between the packet size information in the resource pool configuration information of any resource pool and the CBR threshold may be one-to-one, for example, please refer to table 4, where in table 4, one packet size information corresponds to one CBR threshold.

TABLE 4

The mapping relationship between the packet size information and the CBR threshold in the resource pool configuration information of any resource pool may also be many-to-one, that is, multiple packets of size information correspond to one CBR threshold, for example, please refer to table 5, where in table 5, multiple packets of size information correspond to one CBR threshold, and one packet of size information corresponds to one CBR threshold.

TABLE 5

Packet size information	CBR threshold value
		Packet size information 1 and packet size information 2	CBR threshold value 1
Packet size information 3	CBR threshold value 2
		Packet size information 4 and packet size information 5	CBR threshold value 3
……	……

For better understanding, how to determine whether the target resource pool is a sending resource pool is described here by taking a target resource pool as an example, and thus the method can be generalized to a plurality of target resource pools. Assuming that a mapping relation between packet size information of a certain target resource pool and a CBR threshold is as shown in table 6-1 below, where the packet size information includes a strength number, a current CBR measurement value of the target resource pool is 60%, assuming that a size of a packet to be sent is 4, determining a first target CBR threshold to be 80% according to the table 6-1 and the size of the packet to be sent, and selecting the target resource pool as a sending resource pool because the CBR measurement value (60%) is smaller than the first target CBR threshold (80%); assuming that the size of the data packet to be transmitted is 6, the first target CBR threshold is determined to be 40% according to table 6-1 and the size of the data packet to be transmitted, and since the CBR measurement value (60%) is greater than the first target CBR threshold (40%), the target resource pool is not selected as the transmission resource pool.

TABLE 6

Packet size information	CBR threshold value
		0、1	50％
3、4、5	80％
		6	40％
……	……

In some embodiments, the packet size information may also be the packet size, please refer to table 6-2, assuming that the packet size information is a packet size range, and the mapping relationship between the packet size information of a certain target resource pool and the CBR threshold is as follows table 6-2, where the current CBR measurement value of the target resource pool is 50%, assuming that the packet size to be sent is 600Bytes, according to table 6-2 and the packet size to be sent, it is determined that the first target CBR threshold is 30%, and since the CBR measurement value (50%) is greater than the first target CBR threshold (30%), the target resource pool is not selected as the sending resource pool; assuming that the size of the data packet to be sent is 1500Bytes, the first target CBR threshold is determined to be 90% according to table 6-2 and the size of the data packet to be sent, and since the CBR measurement value (50%) is smaller than the first target CBR threshold (90%), the target resource pool is selected as the sending resource pool.

……	……

When the resource pool configuration information includes the threshold value of the number allowed to be sent, according to the size of the data packet to be sent, the current state information of the resource pool, and the resource pool configuration information of the target resource pool, selecting a sending resource pool from the target resource pool may be: calculating the number of available resources to be transmitted of the target resource pool according to the current available resource amount of the target resource pool and the size of the data packet to be transmitted (the number of available resources = the available resource amount/the size of the data packet to be transmitted, wherein, if the quotient of the available resource amount divided by the size of the data packet to be transmitted is not an integer, rounding down can be performed), the current state information of the resource pool includes the current available resource amount of the target resource pool, and then selecting at least one resource pool with the number of available resources larger than the threshold value of the allowed number of resources to be transmitted from the target resource pool as the transmission resource pool. For the method for acquiring the current available resource amount of the target resource pool, reference is made to the aforementioned method for acquiring the current occupied resource amount, which is not described herein again. For better understanding, how to determine whether the target resource pool is a sending resource pool is described by taking a target resource pool as an example, and thus the method can be generalized to a plurality of target resource pools. Assuming that the threshold value of the number of allowed transmissions of a certain target resource pool is 5, the current available resource amount of the target resource pool is 10000Bytes, and assuming that the size of a data packet to be transmitted is 1000Bytes, the number of the allowed transmissions is greater than the threshold value of the number of allowed transmissions, and the resource pool is selected as a transmission resource pool; and if the size of the data packet to be sent is 5000Bytes, the number of the data packets to be sent is smaller than the threshold value of the number of the data packets to be sent, and the resource pool is not selected as a sending resource pool.

For example, when the resource pool configuration information includes a threshold of the number of allowed transmissions, packet size information, and a CBR threshold, selecting a transmission resource pool from the target resource pool may be: and selecting at least one resource pool as a sending resource pool, wherein the resource pool comprises the CBR measured value and the current available resource amount of the target resource pool, the CBR measured value of the resource pool, the number of allowed sending, the data packet size information and the CBR threshold value, the size of the data packet to be sent is matched with the data packet size information, the CBR measured value is matched with the CBR threshold value, and the number of the allowed sending is larger than the threshold value of the number of allowed sending.

In this embodiment, the resource pool configuration information further includes a priority of the data packet. The resource pool configuration information is different, and the mode of selecting the resource pool to be transmitted from the target resource pool according to the size of the data packet to be transmitted, the current state information of the resource pool and the resource pool configuration information of the target resource pool is also different.

When the resource pool configuration information includes data packet size information, a CBR threshold of channel occupancy ratio, a data packet priority, and a mapping relationship between the data packet priority and the CBR threshold, selecting a transmission resource pool from the target resource pool according to the size of the data packet to be transmitted, current state information of the resource pool, and resource pool configuration information of the target resource pool may be: selecting at least one matched second resource pool from the target resource pools according to the size of the data packet to be sent and the size information of the data packet, and determining a second target CBR threshold value matched with the priority of the data packet to be sent according to the mapping relation between the priority of the data packet in the second resource pool and the CBR threshold value and the priority of the data packet to be sent; and selecting at least one resource pool with the CBR measured value smaller than a second target CBR threshold value from the second resource pools as a sending resource pool, wherein the current state information of the resource pools comprises the CBR measured value of the second resource pools, and the CBR measured value is generated according to the current occupied resource amount of the resource pools and the total resource amount of the resource pools. For the confirmation method of the matching between the size of the data packet to be sent and the size information of the data packet, and the acquisition method of the CBR measurement value, reference is made to the foregoing description, and details are not repeated here. The mapping relationship between the packet priority and the CBR threshold in the resource pool configuration information of any resource pool may be one-to-one, for example, please refer to table 7, where in table 7, one packet priority corresponds to one CBR threshold.

TABLE 7

The mapping relationship between the packet priorities and the CBR threshold values in the resource pool configuration information of any resource pool may also be many-to-one, that is, multiple packet priorities correspond to one CBR threshold value, for example, please refer to table 8, where in table 8, there are multiple packet priorities corresponding to one CBR threshold value, and there is also one packet priority corresponding to one CBR threshold value.

TABLE 8

For better understanding, how to determine whether the second resource pool is a sending resource pool is described by taking a second resource pool as an example, and thus the method can be generalized to a plurality of second resource pools. In this embodiment, it is assumed that a mapping relationship between a priority of a packet in a certain second resource pool and a CBR threshold is shown in table 8, a CBR measurement value of the second resource pool is 30%, it is assumed that a priority of a packet to be sent is a priority 3, a second target CBR threshold is a CBR threshold 2, and if 30% of the priority is greater than or equal to the CBR threshold 2, the second resource pool is not selected as a sending resource pool; and if the 30% is smaller than the CBR threshold value 2, selecting the second resource pool as a sending resource pool.

When the resource pool configuration information includes the packet size information, the CBR threshold, the packet priority, and the mapping relationship between the packet size information, the packet priority, and the CBR threshold, selecting a sending resource pool from the target resource pool according to the size of the packet to be sent, the current state information of the resource pool, and the resource pool configuration information of the target resource pool includes: determining a third target CBR threshold value matched with the size of the data packet to be sent and the priority of the data packet to be sent according to the mapping relation among the size information of the data packet, the priority of the data packet and the CBR threshold value of the target resource pool, and selecting at least one resource pool with a CBR measured value smaller than the third target CBR threshold value from the target resource pool as a sending resource pool, wherein the current state information of the resource pool comprises the CBR measured value of the target resource pool, and the CBR measured value is generated according to the current occupied resource amount of the resource pool and the total resource amount of the resource pool, and the obtaining mode of the CBR measured value of the target resource pool is referred to the above description, which is not described herein again. In some embodiments, the mapping relationship between the packet size information, the packet priority and the CBR threshold of one resource pool may be that different priority and different packet size information correspond to different CBR thresholds, for example, please refer to table 9, where it is assumed that the packet size information is a strength number, and in table 9, different priority and different strength numbers correspond to different CBR thresholds.

TABLE 9

In some embodiments, in the mapping relationship between the packet size information, the packet priority, and the CBR threshold of one resource pool, the same CBR threshold may exist for the same priority and the different strength numbers, for example, please refer to table 10, where in table 10, the priorities are all 1, and the strength numbers 0 and 1 correspond to the same CBR threshold.

TABLE 10

In some embodiments, in the mapping relationship between the packet size information, the packet priority, and the CBR threshold of one resource pool, there may be one CBR threshold corresponding to different priorities and different strength numbers, for example, please refer to table 11, where there are CBR thresholds corresponding to table 11 where the priority is 1 and the strength number is 0; the CBR threshold values corresponding to the priority level of 2 and the strength number of 1 are the same.

TABLE 11

It should be noted that the mapping relationship among the packet size information, the packet priority, and the CBR threshold of any resource pool is not limited to the above-mentioned exemplary manner, and the mapping relationship among the packet size information, the packet priority, and the CBR threshold may be arbitrary, as long as the only CBR threshold can be found according to the packet priority to be sent and the packet size to be sent.

It should be noted that, although in the above example, the packet size information includes the strength number in the mapping relationship among the packet size information, the packet priority and the CBR threshold, in some embodiments, the packet size information includes a packet size range in the mapping relationship among the packet size information, the packet priority and the CBR threshold, and at this time, the size of the packet to be sent is the size of the packet to be sent.

For better understanding, how to determine whether the target resource pool is a sending resource pool is described by taking a target resource pool as an example, and thus the method can be generalized to a plurality of target resource pools. In this embodiment, it is assumed that a mapping relationship between packet size information, a packet priority, and a CBR threshold of a certain target resource pool is as shown in table 9 above, a CBR measurement value of the target resource pool is 20%, size information of a packet to be sent is 2, a priority of the packet to be sent is 3, and if the look-up table 9 is found, a third target CBR threshold of the target resource pool is 15, and if the CBR measurement value (20%) is greater than 15, the resource pool is not selected as a sending resource pool; and if the CBR measured value (20%) is less than or equal to the threshold value 15, selecting the resource pool as a sending resource pool.

In some embodiments, the mapping relationship between the threshold of the allowed transmission number of any resource pool and the priority of the data packet may be in a one-to-one correspondence, for example, please refer to table 12, in which table 12, the priority of the data packet and the threshold of the allowed transmission number are in a one-to-one correspondence:

TABLE 12

Packet priority	Allowed number threshold
		Priority 1	Allowed transmission number threshold value 1
Priority 2	Allowed transmission number threshold 2
		Priority 3	Allowed transmission number threshold value 3
……	……

In some embodiments, the mapping relationship between the threshold of the allowed transmission number of any resource pool and the priority of the data packet may be one-to-many, for example, please refer to table 13, in table 13, a plurality of priorities of the data packet may correspond to one threshold of the allowed transmission number:

watch 13

Packet priority	Allowed transmission number threshold
		Priority 1, 3	Allowed transmission number threshold value 1
Priority 2	Allowed transmission number threshold 2
		Priority 5, 6, 7	Allowed transmission number threshold value 3
……	……

For better understanding, how to determine whether the target resource pool is a sending resource pool is described by taking a target resource pool as an example, and thus the method can be generalized to a plurality of target resource pools. In this embodiment, it is assumed that a mapping relationship between the threshold of the number of allowed transmissions of a certain target resource pool and the priority of the data packet is as shown in table 13 above, the current number of the target resource pool that can be transmitted is 6, the priority of the data packet to be transmitted is 5, table 13 is searched, the threshold of the number of allowed transmissions of the first target is the threshold of the number of allowed transmissions of 3, and if the number of the allowed transmissions (6) is less than or equal to the threshold of the number of allowed transmissions of 3, the target resource pool is not selected as the transmission resource pool.

It should be noted that, the resource pool configuration information may also include three selection manners of sending resource pools of data packet priorities.

In this embodiment, after the transmission resource pool is selected, the data packet to be transmitted may be transmitted through the resource in the transmission resource pool. When the data packet to be sent is sent through the resources in the sending resource pool, a target sending resource pool can be selected from the sending resource pool through a preset rule, and then the data packet to be sent is sent through the target sending resource pool. The preset rule may be that a preset number of target transmission resource pools are selected from the transmission resource pools according to the current available resource amount or CBR measurement value of the transmission resource pools in the descending order of the current available resource amount of the transmission resource pools, or a preset number of target transmission resource pools are selected from the transmission resource pools in the descending order of the current CBR measurement value of the transmission resource pools, where the preset number may be 1, 2, 3, or the like. In some embodiments, if the CBR measurement values of the transmission resource pools are obtained in the process of selecting the transmission resource pools, the preset rule is to select a preset number of target transmission resource pools from the transmission resource pools according to the CBR measurement values of the transmission resource pools obtained in the process of selecting the transmission resource pools and according to a sequence from low to high of the CBR measurement values. In some embodiments, if the current available resource amount of the transmission resource pool is obtained in the process of selecting the transmission resource pool, the preset rule is to select a preset number of target transmission resource pools from the transmission resource pools according to the current available resource amount of the transmission resource pool in the process of selecting the transmission resource pool, in the order from high to low of the available resource amount.

In some implementation processes, a terminal receives resource pool configuration information of each resource pool sent by a base station, where the resource pool configuration information includes geographical position indication information, the resource pool configuration information also includes a number threshold allowed to be sent, and/or a data packet size information and a channel occupancy ratio CBR threshold, and then selects at least one resource pool from each resource pool as a sending resource pool according to the size of a data packet to be sent, current state information of the resource pool, current position information, and resource pool configuration information of each resource pool, and because the resource pool configuration information also includes the number threshold allowed to be sent, and/or the data packet size information and the channel occupancy ratio CBR threshold, a sending resource pool selected from each resource pool is more matched with a data packet to be sent according to the size of the data packet to be sent, the current state information of the resource pool, the current position information, and the resource pool configuration information of each resource pool, thereby improving the matching degree of the sending resource pool and the data packet to be sent.

Example two:

in order to solve a problem that a size of a to-be-sent data packet is not matched with a sending resource pool due to an existing mode for selecting the sending resource pool according to geographical position indication information and a CBR, for example, a size of the to-be-sent data packet is larger than a total resource amount of the sending resource pool, so that the selected sending resource pool cannot meet a transmission requirement, an embodiment of the present invention provides a resource pool selection method, which, as shown in fig. 2, includes:

The geographical position indication information may include longitude, latitude, and other information for indicating the geographical position. The threshold value of the number of allowed data packets to be transmitted is the threshold value of the number of data packets allowed to be transmitted by the resource pool, and when the quotient obtained by dividing the total amount of the available resources of the resource pool by the size of the data packets to be transmitted is greater than the threshold value of the number of allowed data packets to be transmitted configured for the resource pool, the data packets to be transmitted are matched with the resource pool, and the data packets to be transmitted can be transmitted by using the resources in the resource pool. The CBR threshold includes a CBR threshold configured for the resource pool, and when the current CBR value of the resource pool is smaller than the CBR threshold, the resource in the resource pool is selected to send the data packet, where CBR = occupied resource amount/total resource amount. The packet size information includes a size of a packet configured for the resource pool, wherein the packet size information may be configured according to a total resource amount of the resource pool.

The force number can be letters and/or numbers, and the force number corresponds to the size range of the data packet one by one. In some embodiments, the difference in packet size ranges may be the same, and in some embodiments, the difference in packet size ranges may be different.

When configuring the strength number of each resource pool, the data packet size information of each resource pool may be configured according to the total resource amount of each resource pool, for example, assuming that the strength configuration information of the data packet is shown in table 14, the total resource amount of resource pool G is 5000Bytes, the total resource amount of resource pool H is 50000Bytes, and the total resource amount of resource pool I is 50000000Bytes, the strength number of each resource pool refers to the following table 15:

Resource pool H	50000Bytes	0，1，2，3，4
			Resource pool I	50000000Bytes	0，1，2，3，4，5

The base station may send the data packet strength configuration information to the terminal through a system broadcast message and/or a Radio Resource Control (RRC) dedicated signaling.
