Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a method, device, and system for data transmission. Background Art

[0002] With the development of wireless communication technology, people's demand for high data rates and user experience is growing. Consequently, people have a growing need for proximity services that allow them to understand and communicate with people and things around them. This has led to the emergence of device-to-device (D2D) technology, which allows multiple D2D-enabled user equipment (UE) to directly discover and communicate with each other, with or without network infrastructure. Within the Long Term Evolution (LTE) network technology proposed by the 3rd Generation Partnership Project (3GPP), the vehicle-to-everything (V2X) technology has been further proposed. In the user resource self-selection mode in the V2X scenario, the resource pool configuration information includes at least two types of resource pools. One is the resource pool type in which the UE selects resources for data transmission based on sensing, and the other is the resource pool type in which the UE selects resources for data transmission based on partial-sensing, or the resource pool type in which resources are randomly selected for data transmission. Since the randomly selected UE excludes resources based on the sensing results, the probability of collision between the randomly selected resources and resources selected by other users will increase.

[0003] At present, in order to reduce the probability of resource collision, different types of resource pools for resource selection based on listening and resource selection based on partial listening can be configured separately, and the time and frequency resources of the resource pools do not completely overlap, so that the interference between UEs that make different resource selections can be reduced, that is, the UE that selects resources based on listening and the UE that randomly selects resources are in different resource pools for resource selection.

[0004] However, since the Quality of Service (QoS) of each data is different, the priority of the Physical Sidelink Shared Channel (PSSCH) transmitted each time is also different. When resources are selected in different resource pools, in the transmission mode of randomly selecting resources, the probability of collision between high-priority PSSCH and low-priority PSSCH is similar. Therefore, when resources are selected at the same time, a collision between high-priority PSSCH and low-priority PSSCH may occur. Therefore, the QoS requirement of high-priority PSSCH cannot be guaranteed, thereby reducing the QoS of high-priority PSSCH. Summary of the Invention

[0005] The embodiments of the present application provide a method, apparatus, and device for data transmission, which are used to reduce the probability of collision between a high-priority PSSCH and a low-priority PSSCH, thereby ensuring the QoS of the higher-priority PSSCH and improving the QoS of the high-priority PSSCH.

[0006] In a first aspect, the present application provides a method for data transmission. The method comprises: first obtaining resource pool configuration information including first resource pool information and second resource pool information, wherein the resource pool configuration information may be obtained based on a sidelink bandwidth part (SL-BWP) configuration, and the first resource pool information is used to indicate the first resource pool, and the second resource pool information is used to indicate the second resource pool, and the resource determination mode of the first resource pool includes a resource determination mode of full listening selection, and the resource determination mode of the second resource pool includes at least one of a resource determination mode of partial listening selection and a resource determination mode of random selection. It should be understood that, in actual applications, the resource determination mode of the first resource pool may also include partial listening selection and / or random selection, and the second resource pool may only be used for partial listening selection and / or random selection, and the specific details are not limited here. Then, obtaining a first priority value corresponding to a physical layer sidelink shared channel (PSSCH), wherein the first priority value is the priority corresponding to the PSSCH itself, and the first priority may be indicated in a corresponding SCI. It should be understood that the first priority value may be the priority corresponding to the data carried on the PSSCH, or the first priority value may also be the priority corresponding to the data service carried on the PSSCH. When the first priority value is less than the first priority threshold, the resources for sending PSSCH are determined in the first resource pool by partial listening resource selection determination method and / or random resource selection determination method, and when the first priority value is greater than or equal to the first priority threshold, the resources for sending PSSCH are determined in the second resource pool by partial listening resource selection determination method and / or random resource selection determination method.

[0007] In this embodiment, since a smaller priority value indicates a higher priority, when the first priority value is less than the first priority threshold, the high-priority PSSCH can determine the resources for sending the PSSCH in the first resource pool by partial listening selection resource determination method and / or random selection resource determination method, which can reduce the probability of collision between the high-priority PSSCH and the low-priority PSSCH, thereby ensuring the QoS of the higher-priority PSSCH and thus improving the QoS of the high-priority PSSCH.

[0008] In combination with the first aspect of the embodiment of the present application, in the first implementation manner of the first aspect of the embodiment of the present application, the first resource pool information is also used to indicate random selection configuration information, and the random selection configuration information includes enabling (enabled) the randomly selected resource determination method, or disabling (disabled) the randomly selected resource determination method. Therefore, to determine that the first priority value is less than the first priority threshold, it is also necessary to determine whether the first resource pool information indicates enabling the randomly selected resource determination method. Therefore, when the first resource pool information indicates enabling the randomly selected resource determination method, it can be determined in the first resource pool that the resources for sending PSSCH are determined in the randomly selected resource determination method, and when the first resource pool information indicates disabling enabling the randomly selected resource determination method, then it is determined in the second resource pool that the resources for sending PSSCH are determined in the randomly selected resource determination method. Secondly, the first resource pool information indicates disabling enabling the randomly selected resource determination method. Since the first resource pool disabling enabling random selection, it is determined at this time that the resources for sending PSSCH are determined in the second resource pool in the randomly selected resource determination method.

[0009] In this embodiment, by randomly selecting configuration information to determine whether the first resource pool information can perform a randomly selected resource determination method, a high-priority PSSCH can, when the first resource pool enables the randomly selected resource determination method, determine the resources corresponding to the high-priority PSSCH in the first resource pool using the randomly selected resource determination method, thereby further improving the QoS of the high-priority PSSCH. Secondly, when the randomly selected resource determination method is prohibited, the resources for sending the PSSCH are determined in the second resource pool using the randomly selected resource determination method, which can ensure that the resources can be sent smoothly and limit the resources in the resource pool for sending the PSSCH using the randomly selected resource determination method, thereby improving the feasibility of this solution.

[0010] In combination with the first aspect of the embodiment of the present application, in the second implementation of the first aspect of the embodiment of the present application, the first resource pool information is also used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption. Therefore, when the first resource pool information indicates a resource determination method that enables preemption, it is also necessary to determine whether the first priority value is less than the first priority threshold. When the first priority value is less than the first priority threshold, it can be determined that the resources for sending PSSCH are determined in the first resource pool in a randomly selected resource determination method, and when the first priority value is greater than or equal to the first priority threshold, it is determined that the resources for sending PSSCH are determined in the second resource pool in a randomly selected resource determination method. Secondly, if the first resource pool information indicates a resource determination method that prohibits preemption, then preemption is allowed in the first resource pool. At this time, the first priority value is not considered, that is, the resources for sending PSSCH are determined in the second resource pool in a randomly selected resource determination method.

[0011] In this embodiment, the triggering conditions of the randomly selected resource determination method are associated with the triggering conditions of the preempted resource determination method. When preemption is allowed in the first resource pool, the first priority value must be less than the first priority threshold before random selection can be performed. This improves the conditions for determining the resources for sending PSSCH in the first resource pool using the randomly selected resource determination method, limits the number of PSSCHs sent using the randomly selected resource determination method, and improves the reliability of resources in the high-priority PSSCH sent using the randomly selected resource determination method, thereby further improving the QoS of the high-priority PSSCH.

[0012] In combination with the first aspect of the embodiment of the present application, in a third implementation of the first aspect of the embodiment of the present application, the first resource pool information is further used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption. In this implementation, when the first resource pool information indicates that the resource determination method that enables preemption is prohibited, that is, when enabling preemption in the first resource pool is prohibited, it is necessary to further determine whether the first priority value is less than the first priority threshold. Therefore, when the first priority value is less than the first priority threshold, it can be determined that the resources for sending PSSCH are determined in the first resource pool in a randomly selected resource determination method, and when the first priority value is greater than or equal to the first priority threshold, it is determined that the resources for sending PSSCH are determined in the second resource pool in a randomly selected resource determination method. Secondly, when the first resource pool information indicates a resource determination method that enables preemption, then when enabling preemption in the first resource pool is allowed, the resources for sending PSSCH cannot be determined in the first resource pool in a randomly selected resource determination method. At this time, the first priority value is not considered, that is, it is determined that the resources for sending PSSCH are determined in the second resource pool in a randomly selected resource determination method.

[0013] In this embodiment, since the randomly selected resource determination method will have a performance impact on the resource determination method of full listening selection, preemption may also have an impact on the resource determination method of full listening selection. Therefore, the first resource pool information indicates that the resource determination method that enables preemption is prohibited, and the first priority value is less than the first priority threshold. It can be determined that the resources corresponding to the high-priority PSSCH are sent in the first resource pool using the randomly selected resource determination method, while in other cases, the resources for sending the PSSCH are determined in the second resource pool using the randomly selected resource determination method. This can reduce the interference and conflict effects between random selection and preemption, thereby reducing the collision of the high-priority PSSCH sent in the randomly selected resource determination method, and thus ensuring the QoS of the higher-priority PSSCH.

[0014] In conjunction with the first aspect of the embodiments of the present application, in a fourth implementation of the first aspect of the embodiments of the present application, the first resource pool information is further used to indicate partial listening selection configuration information, and the partial listening selection configuration information includes a resource determination method for enabling partial listening selection, or a resource determination method for disabling partial listening selection. Similar to the first implementation of the first aspect of the embodiments of the present application, after determining that the first priority value is less than the first priority threshold, it is also necessary to determine whether the first resource pool information indicates a resource determination method for enabling partial listening selection. Therefore, when the first resource pool information indicates a resource determination method for enabling partial listening selection, it can be determined in the first resource pool that the resources for sending the PSSCH are determined in the resource determination method for partial listening selection. When the first resource pool information indicates a resource determination method for disabling partial listening selection, then the resources for sending the PSSCH are determined in the second resource pool in the resource determination method for partial listening selection. Secondly, the first resource pool information indicates a resource determination method for disabling partial listening selection. Since the first resource pool disabling partial listening selection, it is determined that the resources for sending the PSSCH are determined in the second resource pool in the resource determination method for partial listening selection.

[0015] In this embodiment, the partial listening selection configuration information is used to determine whether the first resource pool information can perform the resource determination method of partial listening selection. When the resource determination method of partial listening selection is enabled in the first resource pool, the high-priority PSSCH can be determined in the first resource pool in the resource determination method of partial listening selection to determine the resources corresponding to the high-priority PSSCH to be sent, thereby further improving the QoS of the high-priority PSSCH. Secondly, when the resource determination method of partial listening selection is prohibited, the resources for sending the PSSCH are determined in the second resource pool in the resource determination method of partial listening selection, which can ensure that the resources can be sent smoothly and limit the resources for sending the PSSCH in the resource pool in the resource determination method of partial listening selection, thereby improving the feasibility of this solution.

[0016] In combination with the first aspect of the embodiments of the present application, in the fifth implementation manner of the first aspect of the embodiments of the present application, the first resource pool information is also used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption. Similar to the second implementation manner of the first aspect of the embodiments of the present application, when the first resource pool information indicates a resource determination method that enables preemption, it is also necessary to determine whether the first priority value is less than the first priority threshold. When the first priority value is less than the first priority threshold, it can be determined in the first resource pool in a resource determination method selected by partial listening to determine the resources for sending PSSCH, and when the first priority value is greater than or equal to the first priority threshold, it is determined in the second resource pool in a resource determination method selected by partial listening to determine the resources for sending PSSCH. Secondly, the first resource pool information indicates a resource determination method that prohibits preemption. At this time, the first priority value is not considered, that is, it is determined in the second resource pool in a resource determination method selected by partial listening to determine the resources for sending PSSCH.

[0017] In this embodiment, the triggering conditions of the resource determination method for partial listening selection are associated with the triggering conditions of the resource determination method for preemption. When preemption is allowed in the first resource pool, partial listening selection can only be performed if the first priority value is less than the first priority threshold. This improves the conditional requirements for determining the resources for sending PSSCH in the first resource pool using the resource determination method for partial listening selection, limits the number of PSSCHs sent using the resource determination method for partial listening selection, and improves the reliability of resources in sending high-priority PSSCH using the resource determination method for partial listening selection, thereby further improving the QoS of high-priority PSSCH.

[0018] In combination with the first aspect of the embodiments of the present application, in a sixth implementation of the first aspect of the embodiments of the present application, the first resource pool information is further used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption. Similar to the third implementation of the first aspect of the embodiments of the present application, in this implementation, when the first resource pool information indicates that the resource determination method that enables preemption is prohibited, that is, when preemption is prohibited in the first resource pool, it is necessary to further determine whether the first priority value is less than the first priority threshold. Therefore, when the first priority value is less than the first priority threshold, it can be determined in the first resource pool to determine the resources for sending PSSCH in a resource determination method selected by partial listening, and when the first priority value is greater than or equal to the first priority threshold, it is determined that the resources for sending PSSCH in the second resource pool are determined by a resource determination method selected by partial listening. Secondly, the first resource pool information indicates a resource determination method that enables preemption. At this time, the first priority value is not considered, that is, the resources for sending PSSCH in the second resource pool are determined by a resource determination method selected by partial listening.

[0019] In this embodiment, since the resource determination method of partial listening selection will have a performance impact on the resource determination method of full listening selection, preemption may also have an impact on the resource determination method of full listening selection. Therefore, the first resource pool information indicates that the resource determination method that enables preemption is prohibited, and the first priority value is less than the first priority threshold. It can be determined that the resources corresponding to the high-priority PSSCH are determined in the first resource pool by the resource determination method of partial listening selection, and in other cases, the resources for sending PSSCH are determined in the second resource pool by the resource determination method of partial listening selection. This can reduce the interference and conflict effects between partial listening selection and preemption, thereby reducing the collision of high-priority PSSCH sent by the resource determination method of partial listening selection, and thus ensuring the QoS of PSSCH with higher priority.

[0020] In combination with any one of the first aspect of the embodiments of the present application to the sixth implementation of the first aspect of the embodiments of the present application, in the seventh implementation of the first aspect of the embodiments of the present application, when the transmission power corresponding to the PSSCH is less than or equal to the transmission power threshold, a step of determining the resources for sending the PSSCH in the first resource pool by partial listening selection resource determination method and / or random selection resource determination method is executed.

[0021] In this embodiment, a condition is specifically defined for executing the step of determining the resources for sending PSSCH in the first resource pool by partial listening selection resource determination method and / or random selection resource determination method. PSSCH will only be sent in the first resource pool when the condition that the transmission power corresponding to PSSCH is less than or equal to the transmission power threshold is met, thereby improving the feasibility of this solution.

[0022] In combination with any one of the first aspect of the embodiments of the present application to the sixth embodiment of the first aspect of the embodiments of the present application, in the eighth embodiment of the first aspect of the embodiments of the present application, when the remaining battery level of the terminal device is less than or equal to the power threshold, a step of determining the resources for sending PSSCH in the first resource pool by partial listening selection resource determination method and / or random selection resource determination method is executed.

[0023] In this embodiment, another condition for executing the step of determining the resources for sending PSSCH in the first resource pool by partial listening selection resource determination method and / or random selection resource determination method is specifically limited. PSSCH will only be sent in the first resource pool when the condition that the battery remaining is less than or equal to the power threshold is met, thereby improving the feasibility of this solution and providing another possibility of executing this step, thereby improving the flexibility of this solution.

[0024] In combination with any one of the first aspect of the embodiments of the present application to the sixth embodiment of the first aspect of the embodiments of the present application, in the ninth embodiment of the first aspect of the embodiments of the present application, when the terminal device determines to enter the target state according to the environmental state, it executes the step of determining the resources for sending PSSCH in the first resource pool by partially listening and selecting resources and / or randomly selecting resources.

[0025] In this embodiment, another condition for executing the step of determining the resources for sending PSSCH in the first resource pool by partial listening selection resource determination method and / or random selection resource determination method is specifically limited. PSSCH will be sent in the first resource pool only when the conditions for the terminal device to enter the target state according to the environmental state are met, thereby improving the feasibility of this solution and providing another possibility of executing this step, thereby improving the flexibility of this solution.

[0026] In combination with the seventh implementation manner of the first aspect of the embodiments of the present application, in the tenth implementation manner of the first aspect of the embodiments of the present application, the transmit power threshold value may be determined in different ways. For example, the transmit power threshold value may be obtained according to the configuration of the network device, or obtained through pre-configuration, or obtained based on an indication of sidelink control information (SCI) by other terminal devices, or obtained based on a sidelink medium access control control element (SL MACCE) configuration by other terminal devices. In actual applications, the transmit power threshold value may also be obtained by other terminal devices through sidelink communication radio resource control configuration, or obtained by factory settings, or obtained by pre-definition. Therefore, the specific power threshold value needs to be flexibly determined according to actual conditions.

[0027] In this embodiment, the transmission power threshold can be determined in different ways, which improves the flexibility of determining the transmission power threshold, thereby improving the flexibility of executing the step of sending the PSSCH in the first resource pool, thereby improving the flexibility of this solution.

[0028] In combination with the seventh implementation manner of the first aspect of the embodiments of the present application, in the eleventh implementation manner of the first aspect of the embodiments of the present application, the transmit power threshold may also be related to at least one of a congestion control parameter and a quality of service parameter. Specifically, the congestion control parameter may be a channel busy ratio (CRB), and the quality of service parameter includes but is not limited to communication distance, geographic location information, and priority information of PSSCH, etc., wherein the communication distance may include a minimum communication distance, and the geographic location information may include zone identity (zone ID) indication information, which is not specifically limited here.

[0029] In this embodiment, the sending power threshold is related to different types of parameters, and different types of parameters can be adjusted and selected according to actual conditions, thereby improving the feasibility and flexibility of the sending power threshold, thereby improving the feasibility and flexibility of executing the step of sending PSSCH in the first resource pool, thereby improving the feasibility and flexibility of this solution.

[0030] In combination with the eighth implementation of the first aspect of the embodiments of the present application, in the twelfth implementation of the first aspect of the embodiments of the present application, the power threshold can be determined in different ways. For example, the power threshold can be obtained according to the configuration of the network device, or obtained by pre-configuration, or obtained based on other terminal devices through SCI indication, or based on other terminal devices through SL MAC CE configuration. In actual applications, the power threshold can also be obtained based on other terminal devices through side communication radio resource control configuration, or obtained by factory settings, or predefined, so the specific power threshold needs to be flexibly determined according to actual conditions.

[0031] In this embodiment, the power threshold may be determined in different ways, thereby improving the flexibility of determining the power threshold, thereby improving the flexibility of executing the step of sending the PSSCH in the first resource pool, and thus improving the flexibility of this solution.

[0032] In conjunction with the ninth implementation of the first aspect of the embodiments of the present application, in the thirteenth implementation of the first aspect of the embodiments of the present application, the target state may be that the terminal device is in a non-charging mode, that is, whether the terminal device is powered by an external power supply. If it is in non-charging mode, exemplarily, in a scenario where the handheld terminal device leaves the vehicle and disconnects the vehicle power supply, then the PSSCH is transmitted in the first resource pool. If the terminal device is in charging mode, exemplarily, when the handheld terminal device enters the vehicle and connects to the vehicle power supply, then the PSSCH is transmitted in the second resource pool. Secondly, the target state may also be that the speed corresponding to the terminal device is greater than or equal to a speed threshold, that is, when the speed of the terminal device is at a high speed for a period of time, the terminal device believes that an external power supply is available. exemplarily, in a scenario where the handheld terminal device enters the vehicle and travels on a highway, the resources for transmitting the PSSCH may be determined in the first resource pool using a partial listening selection resource determination method and / or a random selection resource determination method. When the speed of the terminal device is at a low speed for a period of time, exemplarily, in a scenario where the handheld terminal device leaves the vehicle and walks or uses a bicycle, the resources for transmitting the PSSCH may be determined in the second resource pool using a partial listening selection resource determination method and / or a random selection resource determination method. The target states and application scenarios are not exhaustive here, and the specific target states need to be flexibly determined based on the actual situation and environmental conditions.

[0033] In this embodiment, the target state changes based on the environment, and the terminal device is determined to be in a certain state when it is in an unconnected environment, thereby improving the flexibility of the target state, thereby improving the flexibility of executing the step of sending PSSCH in the first resource pool, and further improving the flexibility of this solution.

[0034] In combination with any one of the first aspect of the embodiments of the present application to the thirteenth implementation of the first aspect of the embodiments of the present application, in the fourteenth implementation of the first aspect of the embodiments of the present application, the first priority threshold can be obtained in different ways, for example, it can be provided by resource pool configuration information, or provided by first resource pool information. In actual applications, the first priority threshold can also be predefined or preconfigured, so the first priority threshold needs to be flexibly determined according to actual conditions.

[0035] In this embodiment, the first priority threshold can be determined based on actual conditions in different ways to improve the flexibility of the first priority threshold. Therefore, the comparison between the first priority value and the first priority threshold can be judged based on actual conditions, thereby improving the flexibility of determining the resources for sending PSSCH in the first resource pool by partial listening resource selection determination method and / or random resource selection determination method, thereby improving the flexibility of this solution.

[0036] In combination with any one of the second implementation manner of the first aspect of the embodiments of the present application to the fourteenth implementation manner of the first aspect of the embodiments of the present application, in the fifteenth implementation manner of the first aspect of the embodiments of the present application, since the first resource pool information can also be used to indicate preemption information, the preemption information can also provide a first priority threshold.

[0037] In this embodiment, by providing the first priority threshold through the preemption information, the reliability of the first priority threshold determined when the first resource pool information indicates the preemption information can be improved, thereby improving the reliability of sending resources in the high-priority PSSCH.

[0038] In combination with any one of the first aspect of the embodiments of the present application to the fourteenth implementation of the first aspect of the embodiments of the present application, in the sixteenth implementation of the first aspect of the embodiments of the present application, the resource pool configuration information is also used to indicate N sending resource pools and P receiving resource pools, and the number of receiving resource pools is greater than or equal to the number of sending resource pools, that is, P is greater than or equal to N.

[0039] In this embodiment, the total number of configured receiving resource pools is greater than or equal to the total number of configured sending resource pools, so as to ensure that a terminal device can receive data sent from different sending resource pools as much as possible.

[0040] In combination with any one of the first aspect of the embodiments of the present application to the sixteenth implementation of the first aspect of the embodiments of the present application, in the seventeenth implementation of the first aspect of the embodiments of the present application, the frequency domain resource bandwidth of the initial transmission of the PSSCH sent in a randomly selected manner in the first resource pool is one subchannel, that is, the frequency domain resource bandwidth for retransmission after the initial transmission is reserved through SCI as one or more subchannels. Specifically, the SCI can carry information on the number of subchannels occupied by the PSCCH, that is, the number of subchannels required for subsequent retransmission of the PSSCH. The initial transmission uses a fixed minimum frequency domain scheduling unit, that is, one subchannel.

[0041] In this embodiment, since the bandwidth of the frequency domain resource of the initial transmission is a sub-channel, random transmission can reduce the collision probability of the initial transmission in the frequency domain. The frequency domain resource for retransmission indicated by SCI is not limited by the number of sub-channels and can occupy an appropriate number of sub-channels according to the actual data size, including more than one sub-channel. Other terminal devices (except the first terminal device) can obtain the frequency domain indication information of the SCI through full listening or partial listening to avoid collision of resource selection, thereby improving the reliability of transmission.

[0042] In a second aspect, the present application provides a method for configuring resource pool configuration information. The method includes: sending resource pool configuration information including first resource pool information and second resource pool information to a terminal device, wherein the first resource pool information is used to indicate the first resource pool, and the second resource pool information is used to indicate the second resource pool. The resource determination mode of the first resource pool includes a resource determination mode of full listening selection, and the resource determination mode of the second resource pool includes a resource determination mode of partial listening selection and / or a resource determination mode of random selection. The terminal device can thereby execute the method of the first aspect, obtain a first priority value corresponding to a physical layer sidelink shared channel (PSSCH), and when the first priority value is less than a first priority threshold, determine the resources for sending the PSSCH in the first resource pool using a partial listening selection resource determination mode and / or a random selection resource determination mode, or when the first priority value is greater than or equal to the first priority threshold, determine the resources for sending the PSSCH in the second resource pool using a partial listening selection resource determination mode and / or a random selection resource determination mode.

[0043] In this embodiment, the network device sends resource pool configuration information including first resource pool information and second resource pool information to the terminal device. Since a smaller priority value indicates a higher priority, when the first priority value of the terminal device is less than the first priority threshold, the high-priority PSSCH can determine the resources for sending the PSSCH in the first resource pool by partially listening to select resources and / or randomly selecting resources, which can reduce the probability of collision between the high-priority PSSCH and the low-priority PSSCH, thereby ensuring the QoS of the higher-priority PSSCH and thus improving the QoS of the high-priority PSSCH.

[0044] In conjunction with the second aspect of the embodiments of the present application, in a first implementation manner of the second aspect of the embodiments of the present application, the first resource pool information configured by the network device is further used to indicate random selection configuration information, where the random selection configuration information includes enabling a randomly selected resource determination method, or prohibiting enabling a randomly selected resource determination method. Thus, the terminal device can, through the first implementation manner of the first aspect of the embodiments of the present application, determine, under different conditions, the resources for sending the PSSCH in the first resource pool using a randomly selected resource determination method, or determine the resources for sending the PSSCH in the second resource pool using a randomly selected resource determination method.

[0045] In this embodiment, the network device configures the terminal device with first resource pool information that can indicate random selection configuration information. The terminal device can then further improve the QoS for the high-priority PSSCH based on this first resource pool information. Furthermore, this ensures that resources can be smoothly transmitted and limits the resources in the resource pool that are specifically used to transmit the PSSCH using a randomly selected resource determination method, thereby improving the feasibility of this solution.

[0046] In conjunction with the second aspect of the embodiments of the present application, in a second implementation manner of the second aspect of the embodiments of the present application, the first resource pool information configured by the network device is further used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption. Thus, the terminal device can, through the second implementation manner of the first aspect of the embodiments of the present application, determine the resources for sending the PSSCH in the first resource pool using a randomly selected resource determination method, or determine the resources for sending the PSSCH in the second resource pool using a randomly selected resource determination method, under different conditions.

[0047] In this embodiment, the network device configures the first resource pool information that can indicate preemption information to the terminal device. The terminal device can improve the condition requirements for determining the resources for sending PSSCH in the first resource pool in a randomly selected resource determination manner based on the first resource pool information, limit the number of PSSCHs sent in a randomly selected resource determination manner, and improve the reliability of resources in the high-priority PSSCH sent in a randomly selected resource determination manner, thereby further improving the QoS of the high-priority PSSCH.

[0048] In combination with the second aspect of the embodiments of the present application, in a third implementation manner of the second aspect of the embodiments of the present application, the first resource pool information configured by the network device is further used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption. Thus, the terminal device can, through the third implementation manner of the first aspect of the embodiments of the present application, determine the resources for sending the PSSCH in the first resource pool using a randomly selected resource determination method, or determine the resources for sending the PSSCH in the second resource pool using a randomly selected resource determination method, under different conditions.

[0049] In this embodiment, since the randomly selected resource determination method will have a performance impact on the resource determination method of full listening selection, preemption may also have an impact on the resource determination method of full listening selection. The network device configures the first resource pool information that can indicate preemption information to the terminal device. The terminal device can reduce the interference and conflict effects between random selection and preemption based on the first resource pool information, thereby reducing the collision of high-priority PSSCH sent by the randomly selected resource determination method, and thus ensuring the QoS of the higher-priority PSSCH.

[0050] In combination with the second aspect of the embodiments of the present application, in a fourth implementation manner of the second aspect of the embodiments of the present application, the first resource pool information configured by the network device is further used to indicate partial listening selection configuration information, and the partial listening selection configuration information includes a resource determination method for enabling partial listening selection, or a resource determination method for disabling partial listening selection. Thus, the terminal device can, through the fourth implementation manner of the first aspect of the embodiments of the present application, determine, under different conditions, the resources for sending the PSSCH in the first resource pool using a randomly selected resource determination method, or determine the resources for sending the PSSCH in the second resource pool using a randomly selected resource determination method.

[0051] In this embodiment, the network device configures the terminal device with first resource pool information that indicates partial listening selection configuration information. The terminal device can then improve the QoS for the high-priority PSSCH based on this first resource pool information. Furthermore, this ensures that the terminal device can successfully transmit resources, and specifically limits the resources within the resource pool that can be used to transmit the PSSCH using partial listening selection, thereby improving the feasibility of this solution.

[0052] In combination with the second aspect of the embodiments of the present application, in a fifth implementation manner of the second aspect of the embodiments of the present application, the first resource pool information configured by the network device is further used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption.

[0053] In this embodiment, the triggering conditions of the resource determination method for partial listening selection are associated with the triggering conditions of the resource determination method for preemption. When preemption is allowed in the first resource pool, partial listening selection can only be performed if the first priority value is less than the first priority threshold. This improves the conditional requirements for determining the resources for sending PSSCH in the first resource pool using the resource determination method for partial listening selection, limits the number of PSSCHs sent using the resource determination method for partial listening selection, and improves the reliability of resources in sending high-priority PSSCH using the resource determination method for partial listening selection, thereby further improving the QoS of high-priority PSSCH.

[0054] In combination with the second aspect of the embodiments of the present application, in a sixth implementation manner of the second aspect of the embodiments of the present application, the first resource pool information configured by the network device is further used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption. Similar to the third implementation manner of the second aspect of the embodiments of the present application, the terminal device can, through the sixth implementation manner of the first aspect of the embodiments of the present application, determine the resources for sending the PSSCH in the first resource pool using a randomly selected resource determination method, or determine the resources for sending the PSSCH in the second resource pool using a randomly selected resource determination method, under different conditions.

[0055] In this embodiment, since the resource determination method of partial listening selection will have a performance impact on the resource determination method of full listening selection, preemption may also have an impact on the resource determination method of full listening selection. Therefore, the terminal device can reduce the interference and conflict between partial listening selection and preemption, thereby reducing the collision of high-priority PSSCH sent by the resource determination method of partial listening selection, and thus ensuring the QoS of the higher-priority PSSCH.

[0059] In this embodiment, by providing the first priority threshold through the preemption information, the reliability of the first priority threshold determined when the first resource pool information indicates the preemption information can be improved, thereby improving the reliability of sending resources in the high-priority PSSCH.

[0127] The technical solution provided by this application is further described below with reference to the accompanying drawings and examples. It should be understood that the system structure and business scenarios provided in the examples of this application are mainly for illustrating possible implementation methods of the technical solution of this application and should not be interpreted as the sole limitation of the technical solution of this application. It is known to those skilled in the art that with the evolution of the system structure and the emergence of new business scenarios, the technical solution provided by this application is also applicable to similar technical problems.

[0128] The terms "first," "second," "third," "fourth," and the like (if any) in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0129] In order to better understand the data transmission method, device and apparatus disclosed in the embodiments of the present application, first, the system architecture of the communication system used in the embodiments of the present application is described. The present invention is applied in a system where terminal devices such as D2D and V2X communicate directly with each other, and in this communication system, multiple terminal devices are allowed to directly discover and communicate with each other in the presence or absence of network infrastructure. Therefore, the method disclosed in the embodiments of the present application is applicable to communication scenarios with and without network coverage. Specifically, please refer to Figure 1 , Figure 1 This is a schematic diagram of the system framework in the embodiment of the present application, as shown in the figure, Figure 1 The diagram (A) shows that the terminal devices are in a communication scenario with network coverage, and the terminal devices communicate directly with each other, while the terminal devices and network devices communicate with the user equipment through the evolved universal terrestrial radio access network (UTRAN). Figure 1 The diagram (B) shows that the terminal devices are not all in the communication scenario with network coverage. The terminal devices communicate with each other through PCS, while the terminal devices in the network coverage communicate with the network device through UTRAN and user equipment (UTRAN-to-UE, Uu). Again, Figure 1 The middle figure (C) shows that the terminal devices are in a communication scenario without network coverage, and the terminal devices communicate with each other through PCS.

[0130] Furthermore, the application scenario of Internet of Vehicles was proposed, but due to security considerations, the latency requirement in this scenario is very high. Therefore, under the LTE technology network proposed by 3GPP, V2X Internet of Vehicles technology was proposed. V2X communication refers to the communication between vehicles and any external objects. For details, please refer to Figure 2 , Figure 2This is a schematic diagram of V2X communication in an embodiment of the present application. As shown in the figure, V2X communication includes but is not limited to vehicle-to-vehicle (V2V) communication, vehicle-to-pedestrian (V2P) communication, and vehicle-to-network (V2N) communication. Specifically, V2X communication can also include vehicle-to-infrastructure (V2I) communication, etc., and this is not an exhaustive list of V2X communication. Secondly, V2X communication targets high-speed equipment, represented by vehicles, and can be applied to scenarios such as smart cars, autonomous driving, and intelligent transportation systems. Since V2X communication can support communication scenarios with and without network coverage, the resource allocation method of V2X communication can adopt a network access device scheduling mode, for example, such as the Evolved Universal Terrestrial Radio Access Network Node B (E-UTRAN Node B, eNB) scheduling mode and the UE self-selection mode. Based on V2X technology, vehicle users (vehicle UE, V-UE) can send some of their own information, such as location, speed, intention (such as turning, merging, reversing), etc., to the surrounding V-UEs periodically as well as some non-periodic event-triggered information. Similarly, the V-UE will also receive information from surrounding users in real time.

[0131] Secondly, considering the evolved universal terrestrial radio access network and user equipment (UTRAN-to-UE, Uu) air interface transmission, the two parties in wireless communication can include network devices and terminal devices. Secondly, considering the sidelink (SL) air interface transmission, the transmitting and receiving ends of wireless communication are both terminal devices. Therefore, the network device can be a traditional macro base station eNB (evolved node B) in LTE wireless communication systems and traditional universal mobile telecommunications systems (UMTS), a micro base station eNB in ​​heterogeneous network (HetNet) scenarios, a baseband processing unit (BBU) and remote radio unit (RRU) in distributed base station scenarios, a baseband pool (pool) and radio frequency unit (RFU) in cloud radio access network (CRAN) scenarios, and in future wireless communication systems, such as the fifth generation mobile networks (5G) new radio (NR) system, or a gNB. The terminal device may be a vehicle-mounted communication module or other embedded communication module, or a user's handheld communication device, including a mobile phone, a tablet computer, etc., which is not specifically limited here.

[0132] Secondly, some terms or concepts involved in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0133] 1. Resource determination method for full listening.

[0134] The method of selecting resources for data transmission based on sensing can be divided into full sensing and partial sensing according to the number of sensing time units. prco,0 ] All time units included in the time unit are listened to. It should be understood that the time unit used for sending may not be listened to.

[0135] Specifically, resource determination based on interception includes the following process.

[0136] First, the first terminal device generates a PSSCH to be sent at time slot n, and the UE receives the PSSCH in the listening window [n-T0, nT prco,0] receives the PSCCH from the second terminal device in the resource pool within, or receives the PSCCH and PSSCH from the second terminal device. Specifically, detect and decode SCI on PSCCH. Among them, one SCI can schedule at least one transmission. For example, one SCI schedules three transmissions. Then the first transmission of the three transmissions is the initial transmission of the data carried by a PSSCH, and the next two transmissions are retransmissions of the data carried by the PSSCH, or it can be said that the three transmissions are all retransmissions of a certain data. The listening information included in the SCI includes the time-frequency resource information of the second and third retransmissions of the data, the periodic time-frequency resource information reflecting the data service cycle, and the data priority information (priority of PSSCH). It can be understood that at a given moment, the first terminal device reserves a time-frequency resource after the moment for a new transmission or retransmission of a data by sending an SCI, and then the second terminal device learns the time-frequency resource reservation status of the user by decoding the SCI, thereby avoiding selecting the reserved time-frequency resources to reduce resource collisions. The first terminal device and the second terminal device are different terminal devices, and the second terminal device may be at least one terminal device different from the first terminal device.

[0137] Furthermore, if the first terminal device learns from the monitoring information of the SCI of the second terminal device that the time-frequency resource reserved by the second terminal device is within the resource selection window [n+T1, n+T2] of the first terminal device, then the first terminal device can measure the demodulation reference signal (DMRS) of the data or control channel that the second terminal device needs to send on the time-frequency resource based on the monitoring information to obtain the reference signal received power (RSRP), where T1 is used for indication and T2 is used for indication. If the RSRP is greater than the threshold value Th RSRP , the UE excludes the time-frequency resource from the resource selection window. After excluding the unavailable time-frequency resources in the resource selection window, the UE can determine that the remaining time-frequency resources in the resource selection window are available time-frequency resources, and then select a time-frequency resource from the available time-frequency resources to send data. The threshold value can be preset, configured by the access network device, or preconfigured.

[0138] Finally, after excluding unavailable time-frequency resources in the resource selection window, the first terminal device can determine that the remaining time-frequency resources in the resource selection window are available time-frequency resources, and thus select time-frequency resources from the available time-frequency resources to send data.

[0139] It can be seen that the time-frequency resources used by the first terminal device when sending data are based on the first terminal device based on the listening window [n-T0, nT prco,0 ] is selected based on the listening results (i.e. the determined available resources).

[0140] Specifically, in the embodiment of the present application, the interception result refers to the result determined by the above steps, T0 and T prco,0 Used to determine the size of the listening window, T0 and T prco,0 It is a time domain value greater than or equal to 0 and is measured in a time unit. For example, T0 can be the number of slots determined by the sub-carrier spacing (SCS) corresponding to 1100ms, or the number of slots determined by the SCS corresponding to 100ms. prco,0 The value can be a positive integer, such as 1, 2, 3 or 4, according to different SCS. prco,0 The specific value can be determined based on the user terminal's hardware processing capabilities for interception results. Secondly, T1 and T2 are used to determine the size of the selection window. T1 and T2 are time domain values ​​greater than or equal to 0 and expressed in units of one time unit. The specific values ​​of T1 and T2 can be determined based on the terminal device's own latency processing capabilities and the QoS requirements of the data to be sent.

[0141] 2. Resource determination method for partial listening selection.

[0142] The resource determination method of partial listening selection is a method of selecting resources for data transmission based on partial listening selection (partial-sensing). It should be understood that partial listening selection is to listen on several time units within a period of time (for example, within 1100ms, or within 100ms, or a period of time that is equal to the listening window of full listening). The remaining steps are similar to the aforementioned full listening method and will not be repeated here.

[0143] It can be understood that, if the embodiment of the present application does not specifically specify which listening method is used, the resource determination method of the listening described is expressed as the resource determination method of full listening, and it can also be understood that the resource determination method of full listening and the resource determination method of listening are interchangeable. However, whether it is full listening or partial listening selection, resources are selected in the resource selection window (selection window) for sending PSSCH based on the listening results.

[0144] 3. Method for determining randomly selected resources.

[0145] The randomly selected resource determination method is to directly randomly select resources in the resource selection window to send resources in the PSSCH without having to determine the resources based on listening.

[0146] It is understandable that the high-priority terminal device, high-priority PSSCH and high-priority data described in the embodiments of the present application all refer to the priority of the PSSCH sent or received by the terminal device in a time unit. Specifically, the priority is indicated in the SCI corresponding to the scheduling PSSCH, that is, the high priority indicates that the priority (Priority) of the PSSCH is high, and the higher the priority, the higher the QoS requirement of the data carried by the PSSCH. In this embodiment, the priority is represented by the priority value (Priority Value), and it is defined that the higher the priority, the lower the priority value corresponding to the lower the priority, and the lower the priority, the higher the priority value corresponding to the lower the priority. In actual applications, the higher the priority, the higher the priority value corresponding to the higher the priority, and the lower the priority, the lower the priority value corresponding to the lower the priority. The examples in this embodiment are only used to understand this solution and should not be understood as limitations of this application.

[0147] From the above introduction, it can be seen that the terminal device that performs random selection does not exclude resources based on the listening results, which will increase the probability of collision between the randomly selected resources and the resources selected by other users. In order to reduce the probability of resource collision, two different types of resource pools can be configured separately, and the time-frequency resources of the resource pools do not completely overlap, so that the interference between UEs that perform different resource selections can be reduced, that is, the UE that selects resources based on listening and the UE that randomly selects resources are in different resource pools for resource selection. Since the QoS of each data is different, the priority of the PSSCH transmitted each time is also different, and in different resource pools for resource selection, in the transmission mode of randomly selecting resources, the probability of collision between high-priority PSSCH and low-priority PSSCH is similar. Therefore, when performing resource selection at the same time, high-priority PSSCH and low-priority PSSCH may collide, so the QoS requirements of high-priority PSSCH cannot be guaranteed, thereby reducing the QoS of high-priority PSSCH.

[0148] In order to solve the above problems, an embodiment of the present application provides a method for data transmission, which is used to reduce the probability of collision between high-priority PSSCH and low-priority PSSCH, thereby ensuring the QoS of higher-priority PSSCH and improving the QoS of high-priority PSSCH.

[0149] The following describes in detail the data transmission method used in the embodiment of the present application with the first terminal device as the execution subject. Figure 3 , Figure 3 This is a schematic diagram of an embodiment of a method for data transmission in an embodiment of the present application. The method for data transmission includes the following steps.

[0150] S101. A terminal device obtains resource pool configuration information.

[0151] In this embodiment, it is necessary to first obtain resource pool configuration information. The resource pool configuration information is obtained by the first terminal device, specifically the resource pool configuration information sent by the network device received by the first terminal device. The resource pool configuration information can also be obtained based on the sidelink bandwidth part (SL-BWP) configuration. The resource pool configuration information includes first resource pool information and second resource pool information. The first resource pool information is used to indicate the first resource pool, and the second resource pool information is used to indicate the second resource pool. The first resource pool and the second resource pool are resource pools of different types. The first resource pool is a collection of first time-frequency resources, and the second resource pool is a collection of second time-frequency resources. The resource determination method of the first resource pool includes full listening, and the resource determination method of the second resource pool includes at least one of partial listening selection and random selection. It should be understood that in actual applications, the resource determination method of the first resource pool can also include partial listening selection and / or random selection, and the second resource pool can only be used for partial listening selection and / or random selection. The specific details are not limited here.

[0152] Specifically, under network coverage, the first terminal device can obtain resource pool configuration information based on the system information block (SIB) received by the receiving network device, or obtain resource pool configuration information based on the cell-level (cell-specific) radio resource control (RRC) signaling received by the receiving network device, or obtain resource pool configuration information based on the terminal user level (UE-specific) RRC signaling received by the receiving network device. When there is no network coverage, the first terminal device can use the configuration information of the sidelink (SL) resource pool (Resource Pool) pre-configured at the factory of the device as the resource pool configuration information. The aforementioned resource pool configuration information is specifically the configuration information of the SL resource pool.

[0153] Furthermore, the resource pool configuration information is also used for sideline communication between terminal devices, including the terminal devices sending and receiving multiple channels, such as physical layer channels for sideline communication, including but not limited to at least one of a physical sidelink control channel (PSCCH), a PSSCH, a physical sidelink discovery channel (PSDCH), a physical sidelink broadcast channel (PSBCH), and a physical sidelink feedback channel (PSFCH). The service type carried by the PSSCH may include any of a unicast communication type, a multicast communication type, or a broadcast communication type.

[0154] For example, in the time domain of the SL resource pool, one or more time units may be included, and the time units may include but are not limited to a symbol, several symbols, a time slot, a subframe, and a frame, etc., and the one or more time units may be continuous in time or discrete in time. Secondly, in the frequency domain of the SL resource pool, one or more frequency domain units may be included, and the frequency domain units may include but are not limited to a resource element (RE), several REs, a resource block (RB), several RBs, a subchannel, and several subchannels, etc., wherein a subchannel includes one or more RBs that are continuous in the frequency domain, or non-continuous RBs. For ease of understanding, in this embodiment, the time unit is described in terms of time slots, and the time-frequency domain unit is described in terms of subchannels. It can be understood that in actual applications, the time unit may also include but is not limited to the symbols and subframes introduced in the aforementioned embodiments, and the time-frequency domain unit may also include but is not limited to the resource blocks and resource elements introduced in the aforementioned embodiments. The specific time unit and time-frequency domain unit need to be flexibly determined based on actual needs and applications, and are not limited here.

[0155] Optionally, the resource pool configuration information obtained by the first terminal device can also be used to indicate N transmitting resource pools (TxPool) and P receiving resource pools (RxPool). Since the transmitting resource pool is used to send SL and the receiving resource pool is used to receive SL, the total number of configured receiving resource pools is greater than or equal to the total number of configured transmitting resource pools, that is, P is greater than or equal to N. This ensures that the first terminal device can receive data sent from different transmitting resource pools as much as possible. Exemplarily, the transmitting resource pool may include but is not limited to a transmitting resource pool (TxPoolScheduling) for side communication according to network scheduling, a transmitting resource pool (TxPoolSelectedNormal) for side communication according to autonomous resource selection, and a transmitting resource pool (TxPoolSelectedPSNormal) for side communication based on autonomous resource selection based on power saving (PS). Among them, TxPoolSelectedNormal belongs to the first resource pool, and TxPoolSelectedPSNormal belongs to the second resource pool.

[0156] S102. The terminal device obtains a first priority value corresponding to the physical sidelink shared channel PSSCH.

[0157] In this embodiment, a first priority value is obtained. The first priority value is the priority corresponding to the PSSCH itself, which can be indicated in the corresponding SCI, and the first priority value is obtained by the first terminal device. In actual applications, the first priority value can be the priority corresponding to the data carried on the PSSCH, or the first priority value can also be the priority corresponding to the data service carried on the PSSCH.

[0158] Specifically, the first terminal device generates a PSSCH to be sent at time slot n. As can be seen from the above embodiments, priority information corresponding to the PSSCH can be obtained, and the priority information is the first priority value. Then, the first terminal device obtains a first priority threshold.

[0159] Optionally, the first priority threshold may be provided by resource pool configuration information, or provided by the first resource pool information, or be predefined, or preconfigured. When the first resource pool information is also used to indicate preemption information, the first priority threshold may also be provided by the preemption information, i.e., the first priority threshold is equal to the priority threshold for allowing preemption. The specific method for determining the first priority threshold should not be understood as a limitation of the solution.

[0160] Exemplarily, the value range of the first priority can be any integer value from 1 to 8. The first priority threshold value can also be any integer value from 1 to 8, that is, it can be 1, 2, 3, 4, 5, 6, 7 or 8. It should be understood that in actual applications, the first priority threshold value can be any integer value from 1 to 9, that is, it can be 1, 2, 3, 4, 5, 6, 7, 8 or 9. It can be understood that in actual applications, when the value is 9, it means that no matter what the first priority value is, the first priority value is less than the first priority threshold. The first priority threshold value can also be any integer value from 1 to 16, that is, it can be any integer value between 1 and 16. The specific first priority threshold needs to be flexibly determined according to actual conditions and is not limited here. It should be understood that the above examples are only used to understand this solution, and the specific processing method should be flexibly implemented according to actual conditions.

[0161] Furthermore, since a smaller priority value indicates a higher corresponding priority, that is, a higher corresponding QoS requirement, to determine whether the PSSCH is a high priority, it is necessary to determine whether the first priority value corresponding to the PSSCH is less than the first priority threshold. When the first priority value is less than the first priority threshold, execute step 103; when the first priority value is greater than or equal to the first priority threshold, execute step 104.

[0162] S103 , the first priority value is less than the first priority threshold, and the terminal device determines to determine resources for sending the PSSCH in the first resource pool by partial listening selection resource determination method and / or random selection resource determination method.

[0163] In this embodiment, when the first priority value corresponding to the PSSCH to be sent is less than the first priority threshold, the first terminal device determines to send the PSSCH in the first resource pool. Specifically, since the first resource pool is a collection of first time-frequency resources, the first resource pool originally uses a full-listening resource determination method. However, when the first priority value corresponding to the PSSCH is less than the first priority threshold, the full-listening resource determination method is not adopted, and is changed to a partial-listening resource determination method or a randomly selected resource determination method. Therefore, the first terminal device specifically determines the first time-frequency resource for sending the PSSCH in the first resource pool by partial-listening selection and / or random selection.

[0164] Optionally, after determining that the frequency domain resource bandwidth size of the initial transmission of the PSSCH in the first resource pool is one subchannel, the first terminal device further reserves the frequency domain resource bandwidth for retransmission after the initial transmission as one or more subchannels through the SCI. Specifically, the SCI can carry information on the number of subchannels occupied by the PSCCH, that is, the number of subchannels required for subsequent retransmission of the PSSCH. Since the initial transmission uses a fixed minimum frequency domain scheduling unit, that is, one subchannel, for random transmission, the collision probability of the initial transmission in the frequency domain can be reduced. The frequency domain resources for retransmission indicated by the SCI are not restricted by the number of subchannels, and can occupy an appropriate number of subchannels according to the actual data size, including more than one subchannel. Other terminal devices (except the first terminal device) can obtain the frequency domain indication information of the SCI through full listening or partial listening to avoid collisions in resource selection, thereby improving the reliability of transmission.

[0165] Exemplarily, since the first priority threshold can be determined in different ways, in this embodiment, the first priority threshold is provided as resource pool configuration information, and the first resource pool is TxPoolSelectedNormal and the second resource pool is TxPoolSelectedPSNormal as an example for explanation. Taking the randomly selected resource determination method as an example, when the first priority value corresponding to the PSSCH to be sent is less than the first priority threshold, it means that the first terminal device can randomly select a first time-frequency resource from the resources in the TxPoolSelectedNormal resource pool in a resource selection window [n+T1, n+T2] to send the PSSCH. Specifically, at the moment of slot n, the physical layer processing module of the first terminal device is used to report all the time-frequency candidate resources (candidate resource) belonging to the TxPoolSelectedNormal resource pool in the resource selection window [n+T1, n+T2] time slot to the MAC layer processing module of the first terminal device, so that the MAC layer processing module randomly selects a candidate resource, that is, a first resource, for sending the PSSCH, wherein one candidate unit includes at least one sub-channel resource on 1 time slot for sending the PSSCH. For the first resource for sending PSSCH determined by partial listening selection, by listening to several slots, a first time-frequency resource belonging to the TxPoolSelectedNormal resource pool in the resource selection window [n+T1, n+T2] time slot is selected to send PSSCH.

[0166] Specifically, the value ranges of T1 and T2 in the resource selection window are as follows:

[0167] 0≤T1≤T proc，1 ;

[0168] T 2min ≤T2≤packet delay budget;

[0169] T1<T2

[0170] Among them, T proc，1 Used to indicate user processing delay, T proc，1 The minimum value of T can be 0. 2min The remaining packet delay budget (PDB), which can be configured by the network device, pre-configured, or autonomously selected by the user device, indicates the maximum delay required for a packet to be successfully transmitted from the time it is generated at the service layer. The PDB can be a value that measures the delay of data to be transmitted in units such as time slots, subframes, or frames, or in units such as milliseconds (ms) or seconds (s), though the specifics are not limited here.

[0171] It is understood that in time slot n, the remaining PDB is the remaining delay time when the data packet is generated from the business layer to time slot n. For example, in time slot n, if the remaining PDB is 20ms and a time slot is 0.5 milliseconds, then in time slot n+1, the remaining PDB is 19.5ms, in time slot n+2, the remaining PDB is 19ms, in time slot n+3, the remaining PDB is 18.5ms, and so on, and the details are not repeated here. It should be understood that the above examples are only used to understand this solution, and the specific data transmission method should be flexibly implemented according to actual conditions.

[0172] Optionally, if the first priority threshold is predefined as an example, the value of the first priority threshold can be 2, or any integer value between 1 and 9. Since the smaller the priority value, the higher the priority level, the value of the first priority threshold is 2, which means that only the PSCCH with the highest priority (that is, the priority value is 1) can be partially listened to or the PSSCH can be sent by randomly selecting resources in the TxPoolSelectedNormal resource pool, so as to reduce the interference between random selection or partial listening selection and the listening-based selection method.

[0173] S104. The first priority value is greater than or equal to the first priority threshold, and the terminal device determines to partially listen in the second resource pool to select a resource determination method and / or randomly select a resource determination method to determine resources for sending the PSSCH.

[0174] In this embodiment, when the first priority value corresponding to the PSSCH to be transmitted is greater than or equal to the first priority threshold, the first terminal device determines to transmit the PSSCH in the second resource pool. Since the second resource pool is a collection of second time-frequency resources, the second terminal device specifically determines the second time-frequency resource for transmitting the PSSCH in the second resource pool by partial listening selection and / or random selection.

[0175] Exemplarily, in this embodiment, the first priority threshold is provided as the resource pool configuration information, and the first resource pool is TxPoolSelectedNormal and the second resource pool is TxPoolSelectedPSNormal as an example for explanation. When the first priority value corresponding to the PSSCH to be sent is greater than or equal to the first priority threshold, it means that the first terminal device can randomly select a second time-frequency resource from the resources in the TxPoolSelectedPSNormal resource pool in a resource selection window [n+T1, n+T2] to send PSSCH, or can also select a second time-frequency resource through partial listening to send PSSCH. The method of selecting resources by partial listening has been explained in the aforementioned embodiment and will not be repeated here.

[0176] Optionally, if the first priority threshold is predefined as an example, the value of the first priority threshold can be 2, or any integer value between 1 and 9. Since the smaller the priority value, the higher the priority level, the value of the first priority threshold is 2, which means that only the PSCCH with the highest priority (that is, the priority value is 1) can be partially listened to or the PSSCH can be sent by randomly selecting resources in the TxPoolSelectedNormal resource pool, so as to reduce the interference between random selection or partial listening selection and the listening-based selection method.

[0177] It should be understood that step 103 and step 104 have no time sequence relationship and no time sequence limitation, that is, step 103 and step 104 are steps executed when different conditions are met.

[0178] As can be seen from the above embodiments, a high-priority PSSCH (i.e., a PSSCH with a priority lower than the first priority threshold) can select resources from a resource pool with full listening selection in a resource determination method of partial listening selection and / or random selection to send the PSSCH, which is equivalent to allowing the coexistence of different resource selection methods of full listening selection, partial listening selection and / or random selection in the resource pool. A lower-priority PSSCH (i.e., a PSSCH with a priority greater than or equal to the first priority threshold) can select resources from a resource pool with only partial listening selection and / or random selection in a resource determination method of partial listening selection and / or random selection to send the PSSCH.

[0179] It should be noted that the first resource pool information is also used to indicate random selection configuration information, or partial listening selection configuration information, that is, the first terminal device can determine the first time-frequency resource for sending the PSSCH in the first resource pool by randomly selecting the resource determination method, or can also determine the first time-frequency resource for sending the PSSCH in the first resource pool by partially listening to the resource determination method. The two methods are described below respectively:

[0180] 1. Determine to send the PSSCH in a random selection manner in the first resource pool.

[0181] In this embodiment, the first terminal device may determine to send the PSSCH in a random selection manner in the first resource pool. Figure 4 , Figure 4 This is a schematic diagram of another embodiment of the method for data transmission in the embodiment of the present application. As shown in the figure, in this example, the method for data transmission includes the following steps.

[0182] S201. The terminal device obtains resource pool configuration information.

[0183] In this embodiment, the resource pool configuration information needs to be obtained first. The resource pool configuration information is obtained by the first terminal device, specifically the first terminal device receives the resource pool configuration information sent by the network device. The specific resource pool configuration information is similar to that described in step S101 of the above embodiment and will not be repeated here.

[0184] Furthermore, the first resource pool information included in the resource pool configuration information is also used to indicate random selection configuration information, and the random selection configuration information includes a resource determination method that enables random selection, or prohibits the resource determination method that enables random selection.

[0185] S202. The terminal device obtains a first priority value corresponding to the PSSCH.

[0186] In this embodiment, a first priority value is obtained, and the first priority value is the priority corresponding to the PSSCH itself. The first priority value can be indicated in the corresponding SCI, and the first priority value is obtained by the first terminal device. In actual applications, the first priority value can be the priority corresponding to the data carried on the PSSCH, or the first priority value can also be the priority corresponding to the data service carried on the PSSCH. The specific first priority value is similar to that described in step S102 in the aforementioned embodiment and will not be repeated here.

[0187] S203. The terminal device determines resources for sending the PSSCH in a first resource pool by randomly selecting resources to determine the resources.

[0188] In this embodiment, since the first resource pool information is also used to indicate the random selection configuration information, and the random selection configuration information indicated by the first resource pool information includes a resource determination method that enables random selection, that is, when the random selection configuration information is configured, it means that the first terminal device can determine the first time-frequency resource for sending PSSCH in the first resource pool in a randomly selected resource determination method. Alternatively, when the random selection configuration information in the first resource pool information is configured to enable the resource determination method of random selection, that is, the first terminal device can determine the first time-frequency resource for sending PSSCH in the first resource pool in a randomly selected resource determination method. Further, when the random selection configuration information is not configured, or the random selection configuration information in the first resource pool information is configured to prohibit enabling the resource determination method of random selection, that is, the first terminal device cannot determine the first time-frequency resource for sending PSSCH in the first resource pool in a randomly selected resource determination method. It should be understood that the specific method of determining the first time-frequency resource for sending PSSCH in the first resource pool in a randomly selected resource determination method is similar to that described in step S103 in the aforementioned embodiment, and will not be repeated here.

[0189] Exemplarily, the first resource pool is TxPoolSelectedNormal as an example for explanation. When the resource pool information corresponding to TxPoolSelectedNormal includes a resource determination method that enables random selection, the first terminal device selects the first time-frequency resource in the TxPoolSelectedNormal resource pool in a randomly selected resource determination method to send PSSCH. Secondly, when the random selection configuration information in the resource pool information corresponding to TxPoolSelectedNormal is configured to enable a randomly selected resource determination method, the first terminal device can also select the first time-frequency resource in the TxPoolSelectedNormal resource pool in a randomly selected resource determination method to send PSSCH. It should be understood that the above example is only used to understand this solution, and the specific method of determining the resources for sending PSSCH in a randomly selected resource determination method should be flexibly implemented according to actual conditions and needs.

[0190] S204. The terminal device determines resources for sending the PSSCH in the second resource pool by randomly selecting resource determination methods.

[0191] In this embodiment, since the first resource pool information is also used to indicate random selection configuration information, and the random selection configuration information indicated by the first resource pool information includes a resource determination method that prohibits enabling random selection, that is, when the random selection configuration information in the first resource pool information is not configured, or when the random selection configuration information in the first resource pool information is configured to prohibit enabling random selection resource determination, the first terminal device cannot determine the first time-frequency resource for sending PSSCH in the first resource pool in a randomly selected resource determination method. At this time, the first terminal device can determine the second time-frequency resource for sending PSSCH in the second resource pool in a randomly selected resource determination method. It should be understood that the specific method of determining the second time-frequency resource for sending PSSCH in the second resource pool in a randomly selected resource determination method is similar to that described in step S104 in the aforementioned embodiment, and will not be repeated here.

[0192] Exemplarily, in this embodiment, the first resource pool is TxPoolSelectedNormal and the second resource pool is TxPoolSelectedPSNormal as an example for explanation. When the random selection configuration information in the resource pool information corresponding to TxPoolSelectedNormal is not configured, or the random selection configuration information is configured to prohibit enabling the randomly selected resource determination method, the first terminal device cannot select the first time-frequency resource in the TxPoolSelectedNormal resource pool in a randomly selected resource determination method to send PSSCH. At this time, the first terminal device can select the second time-frequency resource in the TxPoolSelectedNormal resource pool in a randomly selected resource determination method to send PSSCH. It should be understood that the above example is only used to understand this solution, and the specific method of determining the resources for sending PSSCH in a randomly selected resource determination method should be flexibly implemented according to actual conditions and needs.

[0193] Optionally, the first resource pool information is further used to indicate preemption information, and the preemption information includes a resource determination method for enabling preemption, or a resource determination method for disabling preemption.

[0194] Specifically, we first introduce the resource determination method for preemption. Preemption allows the high-priority PSSCH transmitted by the first terminal device to preempt the low-priority PSSCH transmitted by the second terminal device. The first terminal device and the second terminal device are different terminal devices, and both the first terminal device and the second terminal device determine resource selection using the full listening resource determination method. Therefore, the second terminal device reserves resources for transmitting the PSSCH at time slot n+k by transmitting the first SCI at time slot n, with a priority value of P1. The first terminal device receives the first SCI at time slot n and decodes it to determine that the PSSCH priority reserved by the first SCI is P1, and reserves resources for transmitting the PSSCH at time slot n+k. Since the priority value of the PSSCH that the first terminal device is about to send is P2, and P2 is less than P1, that is, the priority of the PSSCH that the first terminal device is about to send is higher than the priority of the second terminal device to send PSSCH at slot n+k, the first terminal device will send a second SCI to the second terminal device before slot n+k to inform the second terminal device that the resources reserved at slot n+k are preempted by the PSSCH that the first terminal device is about to send. Therefore, after receiving the second SCI, the second terminal device needs to reselect resources.

[0195] Therefore, since the randomly selected resource determination method is not based on listening, that is, the PSSCH sent by the first terminal device can be sent at any resource location without considering whether other terminal devices have resource reservations, even if a candidate resource is actually reserved by other terminal devices, the first terminal device may choose to send PSSCH at the candidate resource. Therefore, the first terminal device will not listen, that is, it will not decode the corresponding SCI. Therefore, the randomly selected resource determination method is similar to the preempted resource determination method, that is, it preempts a reserved resource. In this embodiment, the first resource pool information indicates that the preemption information is associated with the randomly selected configuration information. Therefore, when the first resource pool information indicates the preemption information, it can include two data transmission methods. One method is that when the preemption information is a resource determination method that enables preemption, and the first priority value is less than the first priority threshold, it can be determined in the first resource pool using the randomly selected resource determination method to determine the resources for sending PSSCH. The other method is that when the preemption information is a resource determination method that prohibits preemption, and the first priority value is less than the first priority threshold, it is determined in the first resource pool using the randomly selected resource determination method to determine the resources for sending PSSCH. The two methods are explained below.

[0196] (1) The preemption information is a resource determination method that enables preemption, and the first priority value is less than the first priority threshold. The resource for sending the PSSCH is determined in the first resource pool by randomly selecting the resource determination method.

[0197] Specifically, the preemption information is a resource determination method that enables preemption, that is, allowing resources for sending PSSCH in a randomly selected resource determination method in the first resource pool, and determining whether the first priority value is less than the first priority threshold. When the first priority value is less than the first priority threshold, it can be determined that the first time-frequency resource for sending PSSCH in the randomly selected resource determination method in the first resource pool is determined. It should be understood that the specific method for determining the first time-frequency resource for sending PSSCH in the randomly selected resource determination method in the first resource pool is similar to the description of step S203 in the aforementioned embodiment, and will not be repeated here.

[0198] Exemplarily, in this embodiment, the first resource pool is TxPoolSelectedNormal as an example for explanation. Therefore, when the preemption information indicated by the TxPoolSelectedNormal resource pool information includes a resource determination method that enables preemption, the preemption information indicated by the TxPoolSelectedNormal resource pool also provides a first priority threshold, that is, the first priority value of the PSSCH that allows preemption must be less than the first priority threshold. If the priority of the PSSCH to be sent by the first terminal device that wants to select resources by random selection is less than the first priority threshold, then the first time-frequency resource for sending PSSCH can be determined in the TxPoolSelectedNormal resource pool in a randomly selected resource determination method, that is, the random selection resource determination method coexists in the TxPoolSelectedNormal resource pool in the form of "preemption" and the full listening resource determination method. It should be understood that the above example is only used to understand this solution. The specific first resource pool and the method of determining the resources for sending PSSCH in a randomly selected resource determination method should be flexibly determined according to actual conditions and needs.

[0199] Secondly, when the preemption information is a resource determination method that enables preemption, and the first priority value is greater than or equal to the first priority threshold, or when the preemption information is a resource determination method that prohibits preemption, that is, the first terminal device determines the second time-frequency resource for sending PSSCH in the second resource pool by randomly selecting a resource determination method. The specific method in which the first terminal device determines the second time-frequency resource for sending PSSCH in the second resource pool by randomly selecting a resource determination method is similar to the description of step S204 in the aforementioned embodiment, and will not be repeated here.

[0200] (2) The preemption information is a resource determination method that prohibits enabling preemption, and the first priority value is less than the first priority threshold, and the resource for sending the PSSCH is determined in the first resource pool by randomly selecting the resource determination method.

[0201] Specifically, since the randomly selected resource determination method will have a performance impact on the resource determination method selected by full listening, preemption may also have an impact on the resource determination method selected by full listening. Therefore, the method of allowing preemption and randomly selected resource determination at the same time through the aforementioned method will increase the impact on the resource determination method of full listening, that is, the collision probability of PSSCH will be increased in the first resource pool. Therefore, in this method, when the first resource pool information indicates that the resource determination method that enables preemption is prohibited and the first priority value is less than the first priority threshold, the first terminal device determines the resources corresponding to the high-priority PSSCH to be sent in the first resource pool in a randomly selected resource determination method. In other cases, the first terminal device determines the resources for sending PSSCH in the second resource pool in a randomly selected resource determination method. This can reduce the interference and conflict effects between random selection, preemption and right-to-listen, thereby reducing the collision of high-priority PSSCH sent in a randomly selected resource determination method, and thus ensuring the QoS of PSSCH with higher priority.

[0202] Therefore, the preemption information is a resource determination method that prohibits enabling preemption, and when the first priority value is less than the first priority threshold, the first terminal device can determine the first time-frequency resource for sending the PSSCH in the first resource pool using the randomly selected resource determination method. It should be understood that the specific method for determining the first time-frequency resource for sending the PSSCH in the first resource pool using the randomly selected resource determination method is similar to that described in step S203 of the aforementioned embodiment, and will not be repeated here.

[0203] Exemplarily, in this embodiment, the first resource pool is TxPoolSelectedNormal as an example for explanation. Therefore, when the preemption information indicated by the TxPoolSelectedNormal resource pool information includes a resource determination method that prohibits enabling preemption, the first terminal device cannot preempt in the TxPoolSelectedNormal resource pool, that is, the priority of the PSSCH to be sent by the first terminal device is less than the first priority threshold, and the first time-frequency resource for sending the PSSCH can be determined in the TxPoolSelectedNormal resource pool in a randomly selected resource determination method. It should be understood that the above example is only used to understand this solution, and the specific first resource pool and the method of determining the resources for sending the PSSCH in a randomly selected resource determination method should be flexibly determined according to actual conditions and needs.

[0204] Secondly, when the preemption information is a resource determination method that prohibits preemption and the first priority value is greater than or equal to the first priority threshold, or when the preemption information is a resource determination method that enables preemption, the second time-frequency resource for sending the PSSCH is determined in the second resource pool using a randomly selected resource determination method. The specific method for determining the second time-frequency resource for sending the PSSCH in the second resource pool using a randomly selected resource determination method is similar to that described in step S204 in the aforementioned embodiment and is not repeated here.

[0205] 2. Determine to send the PSSCH in a partial listening selection manner in the first resource pool.

[0206] In this embodiment, the first terminal device may determine to send PSSCH in a partial listening selection manner in the first resource pool. Figure 5 , Figure 5 This is a schematic diagram of another embodiment of the method for data transmission in the embodiment of the present application. As shown in the figure, in this example, the method for data transmission includes the following steps.

[0207] S301: The terminal device obtains resource pool configuration information.

[0208] In this embodiment, the resource pool configuration information needs to be obtained first. The resource pool configuration information is obtained by the first terminal device, specifically the first terminal device receives the resource pool configuration information sent by the network device. The specific resource pool configuration information is similar to that described in step S101 of the above embodiment and will not be repeated here.

[0209] Furthermore, the first resource pool information included in the resource pool configuration information is also used to indicate partial listening selection configuration information, and the partial listening selection configuration information includes a resource determination method for enabling partial listening selection, or prohibiting a resource determination method for enabling partial listening selection.

[0210] S302. The terminal device obtains a first priority value corresponding to the PSSCH.

[0211] In this embodiment, a first priority value is obtained, and the first priority value is the priority corresponding to the PSSCH itself. The first priority value can be indicated in the corresponding SCI, and the first priority value is obtained by the first terminal device. In actual applications, the first priority value can be the priority corresponding to the data carried on the PSSCH, or the first priority value can also be the priority corresponding to the data service carried on the PSSCH. The specific first priority value is similar to that described in step S102 in the aforementioned embodiment and will not be repeated here.

[0212] S303: The terminal device determines resources for sending the PSSCH in the first resource pool using a resource determination method of partial listening selection.

[0213] In this embodiment, since the first resource pool information is also used to indicate partial listening selection configuration information, and the partial listening selection configuration information indicated by the first resource pool information includes a resource determination method for enabling partial listening selection, that is, when the partial listening selection configuration information is configured, it means that the first terminal device can determine the first time-frequency resource for sending PSSCH in the first resource pool in a resource determination method for partial listening selection. Alternatively, when the partial listening selection configuration information in the first resource pool information is configured to enable a resource determination method for partial listening selection, that is, the first terminal device can determine the first time-frequency resource for sending PSSCH in the first resource pool in a resource determination method for partial listening selection. Further, when the partial listening selection configuration information is not configured, or the partial listening selection configuration information in the first resource pool information is configured to prohibit enabling a resource determination method for partial listening selection, that is, the first terminal device cannot determine the first time-frequency resource for sending PSSCH in the first resource pool in a resource determination method for partial listening selection. It should be understood that the specific method of determining the first time-frequency resource for sending PSSCH in the first resource pool by partially listening to selected resources is similar to that described in step S103 in the aforementioned embodiment, and will not be repeated here.

[0214] Exemplarily, the first resource pool is TxPoolSelectedNormal as an example for explanation. When the resource pool information corresponding to TxPoolSelectedNormal includes a resource determination method that enables partial listening selection, the first terminal device selects the first time-frequency resource in the TxPoolSelectedNormal resource pool in the resource determination method of partial listening selection to send PSSCH. Secondly, when the partial listening selection configuration information in the resource pool information corresponding to TxPoolSelectedNormal is configured to enable the resource determination method of partial listening selection, the first terminal device can also select the first time-frequency resource in the TxPoolSelectedNormal resource pool in the resource determination method of partial listening selection to send PSSCH. It should be understood that the above example is only used to understand this solution, and the specific method of determining the resources for sending PSSCH in the resource determination method of partial listening selection should be flexibly implemented according to actual conditions and needs.

[0215] S304: The terminal device determines resources for sending the PSSCH in the second resource pool using a resource determination method of partial listening selection.

[0216] In this embodiment, since the first resource pool information is also used to indicate partial listening selection configuration information, and the partial listening selection configuration information indicated by the first resource pool information includes a resource determination method for disabling partial listening selection, that is, when the partial listening selection configuration information in the first resource pool information is not configured, or when the partial listening selection configuration information in the first resource pool information is configured to disable the resource determination method for enabling partial listening selection, the first terminal device cannot determine the first time-frequency resource for sending PSSCH in the first resource pool in the resource determination method for partial listening selection. At this time, the first terminal device can determine the second time-frequency resource for sending PSSCH in the second resource pool in the resource determination method for partial listening selection. It should be understood that the specific method of determining the second time-frequency resource for sending PSSCH in the resource determination method for partial listening selection in the second resource pool is similar to that described in step S104 in the aforementioned embodiment, and will not be repeated here.

[0217] Exemplarily, in this embodiment, the first resource pool is TxPoolSelectedNormal and the second resource pool is TxPoolSelectedPSNormal as an example for explanation. When the partial listening selection configuration information in the resource pool information corresponding to TxPoolSelectedNormal is not configured, or the partial listening selection configuration information is configured to prohibit enabling the resource determination method of partial listening selection, the first terminal device cannot select the first time-frequency resource in the TxPoolSelectedNormal resource pool in the resource determination method of partial listening selection to send PSSCH. At this time, the first terminal device can select the second time-frequency resource in the TxPoolSelectedNormal resource pool in the resource determination method of partial listening selection to send PSSCH. It should be understood that the above example is only used to understand this solution, and the specific method of determining the resources for sending PSSCH in the resource determination method of partial listening selection should be flexibly implemented according to actual conditions and needs.

[0218] Optionally, the first resource pool information is further used to indicate preemption information, where the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption.

[0219] Specifically, since the resource determination method of partial frame listening selection is to listen over several time units, that is, the PSSCH sent by the first terminal device will only be sent to a resource location determined according to the results of the partial listening, and will not consider whether other terminal devices have sent SCI to make resource reservations in the time units that have not been listened to, therefore, even if a candidate resource is actually reserved by other terminal devices, the first terminal device only selects the candidate resource based on the partial listening results obtained over the several time units, that is, the first terminal device chooses to send PSSCH over the candidate resource. Therefore, in this case, the resource determination method of partial frame listening selection is equivalent to preempting a reserved resource. In this embodiment, the first resource pool information indicates that the preemption information is associated with the partial frame listening selection configuration information. Therefore, when the first resource pool information indicates the preemption information, two data transmission methods can be included. One method is that the preemption information is a resource determination method that enables preemption. When the first priority value is less than the first priority threshold, it can be determined in the first resource pool that the resource for sending PSSCH is determined by the resource determination method of partial frame listening selection. Another method is to determine resources in which the preemption information indicates that preemption is disabled. When the first priority value is less than the first priority threshold, the resource for transmitting the PSSCH is determined in the first resource pool using a partial frame listening selection method. The two methods are described below.

[0220] (1) The preemption information is a resource determination mode that enables preemption, and the first priority value is less than the first priority threshold. The resource for sending the PSSCH is determined in the first resource pool using the resource determination mode of partial listening selection.

[0221] Specifically, the preemption information is a resource determination method that enables preemption, that is, allowing resources for sending PSSCH in the first resource pool in a resource determination method selected by partial listening, and judging whether the first priority value is less than the first priority threshold. When the first priority value is less than the first priority threshold, it can be determined that the first time-frequency resource for sending PSSCH in the first resource pool is determined in a resource determination method selected by partial listening. It should be understood that the specific method for determining the first time-frequency resource for sending PSSCH in the resource determination method selected by partial listening in the first resource pool is similar to the description of step S303 in the aforementioned embodiment, and will not be repeated here.

[0222] Exemplarily, in this embodiment, the first resource pool is TxPoolSelectedNormal as an example for explanation. Therefore, when the preemption information indicated by the TxPoolSelectedNormal resource pool information includes a resource determination method that enables preemption, the preemption information indicated by the TxPoolSelectedNormal resource pool also provides a first priority threshold, that is, the first priority value of the PSSCH that allows preemption must be less than the first priority threshold. If the priority of the PSSCH to be sent by the first terminal device that wants to select resources through partial listening selection is less than the first priority threshold, then the first time-frequency resource for sending the PSSCH can be determined in the TxPoolSelectedNormal resource pool in the resource determination method of partial listening selection, that is, the partial listening selection resource determination method coexists in the TxPoolSelectedNormal resource pool in the form of "preemption" and the full listening resource determination method. It should be understood that the above example is only used to understand this solution, and the specific first resource pool and the method of determining the resources for sending the PSSCH in the resource determination method of partial listening selection should be flexibly determined according to actual conditions and needs.

[0223] Secondly, when the preemption information is a resource determination method that enables preemption, and the first priority value is greater than or equal to the first priority threshold, or when the preemption information is a resource determination method that prohibits preemption, that is, the first terminal device determines the second time-frequency resource for sending the PSSCH in the second resource pool using the resource determination method selected by partial listening. The specific method of determining the second time-frequency resource for sending the PSSCH in the second resource pool using the resource determination method selected by partial listening is similar to the description of step S304 in the aforementioned embodiment, and will not be repeated here.

[0224] (2) The preemption information is a resource determination mode that prohibits enabling preemption, and the first priority value is less than the first priority threshold, and the resource for sending the PSSCH is determined in the first resource pool using the resource determination mode of partial listening selection.

[0225] Specifically, since the resource determination method of partial listening selection will have a performance impact on the resource determination method of full listening selection, preemption may also have an impact on the resource determination method of full listening selection. Therefore, the resource determination method of preemption and partial listening selection at the same time through the aforementioned method will increase the impact on the resource determination method of full listening, that is, the collision probability of PSSCH will be increased in the first resource pool. Therefore, when the first resource pool information indicates that the resource determination method of enabling preemption is prohibited and the first priority value is less than the first priority threshold, the first terminal device determines the resources corresponding to the high-priority PSSCH to be sent in the first resource pool using the resource determination method of partial listening selection, and in other cases, the resources for sending PSSCH are determined in the second resource pool using the resource determination method of partial listening selection. This can reduce the interference and conflict between partial listening selection and preemption, thereby reducing the collision of high-priority PSSCH sent in the resource determination method of partial listening selection, and thus ensuring the QoS of PSSCH with higher priority.

[0226] Therefore, the preemption information is a resource determination method that prohibits enabling preemption, and when the first priority value is less than the first priority threshold, the first terminal device can determine the first time-frequency resource for sending the PSSCH in the first resource pool by using the resource determination method selected by partial listening. It should be understood that the specific method for determining the first time-frequency resource for sending the PSSCH in the first resource pool by using the resource determination method selected by partial listening is similar to that described in step S303 of the aforementioned embodiment, and will not be repeated here.

[0227] Exemplarily, in this embodiment, the first resource pool is TxPoolSelectedNormal as an example for explanation. Therefore, when the preemption information indicated by the TxPoolSelectedNormal resource pool information includes a resource determination method that prohibits enabling preemption, the first terminal device cannot preempt in the TxPoolSelectedNormal resource pool, that is, the priority of the PSSCH to be sent by the first terminal device is less than the first priority threshold, and the first time-frequency resource for sending the PSSCH can be determined in the TxPoolSelectedNormal resource pool in a resource determination method selected by partial listening. It should be understood that the above example is only used to understand this solution, and the specific first resource pool and the method of determining the resources for sending the PSSCH in a resource determination method selected by partial listening should be flexibly determined according to actual conditions and needs.

[0228] Secondly, when the preemption information is a resource determination method that prohibits preemption and the first priority value is greater than or equal to the first priority threshold, or when the preemption information is a resource determination method that enables preemption, the second time-frequency resource for sending the PSSCH is determined in the second resource pool using the resource determination method selected by partial listening. The specific method for determining the second time-frequency resource for sending the PSSCH in the second resource pool using the resource determination method selected by partial listening is similar to that described in step S304 in the aforementioned embodiment and is not repeated here.

[0229] In the above-mentioned embodiment, a method for the first terminal device to determine the transmission of PSSCH in the first resource pool is introduced. Furthermore, the first terminal device should determine the resources for transmitting PSSCH in the first resource pool by partial listening selection resource determination method and / or random selection resource determination method when any of the following three conditions are met.

[0230] The first condition is that the transmit power corresponding to the PSSCH is less than or equal to the transmit power threshold.

[0231] Specifically, the transmit power threshold can be obtained according to the configuration of the network device, or obtained through pre-configuration, or obtained based on other terminal devices through SCI indication, or obtained based on the second terminal device through SL MAC CE configuration. In actual applications, the transmit power threshold can also be obtained by the second terminal device through the side communication radio resource control configuration, or, obtained by factory settings, or, predefined. Specifically, the second terminal device and the first terminal device are different terminal devices, and the side communication radio resource control can be PC5-RRC. Therefore, the specific power threshold needs to be flexibly determined according to actual conditions.

[0232] In one possible implementation, the transmit power threshold may also be related to at least one of a congestion control parameter and a quality of service parameter. Specifically, the congestion control parameter may be a CRB, and the quality of service parameter includes, but is not limited to, communication distance, geographic location information, and PSSCH priority information. The communication distance may include a minimum communication distance, and the geographic location information may include area identification indication information, which are not specifically limited herein.

[0233] The second condition is that the remaining battery level of the first terminal device is less than or equal to a power threshold.

[0234] Specifically, the power threshold can be obtained according to the configuration of the network device, or obtained through pre-configuration, or obtained based on other terminal devices through SCI indication, or obtained based on the second terminal device through SL MAC CE configuration. In actual applications, the power threshold can also be obtained by the second terminal device through the side communication radio resource control configuration, or, obtained by factory settings, or, predefined. Specifically, the second terminal device and the first terminal device are different terminal devices, and the side communication radio resource control can be PC5-RRC. Therefore, the specific power threshold needs to be flexibly determined according to actual conditions.

[0235] The third condition is that the first terminal device determines to enter the target state according to the environmental state.

[0236] Specifically, the target state may be that the terminal device is in non-charging mode, that is, whether the terminal device is powered by an external power supply. If it is in non-charging mode, for example, in a scenario where the handheld terminal device leaves the vehicle and disconnects the vehicle power supply, then PSSCH is sent in the first resource pool. The terminal device is in charging mode, for example, when the handheld terminal device enters the vehicle and connects to the vehicle power supply, then PSSCH is sent in the second resource pool. Secondly, the target state may also be that the speed corresponding to the terminal device is greater than or equal to the speed threshold, that is, when the speed of the terminal device is at a higher speed for a period of time, the terminal device believes that external power can be provided. For example, in a scenario where the handheld terminal device enters the vehicle and travels on a highway, it can be determined in the first resource pool to determine the resources for sending PSSCH by partial listening and selecting resources and / or randomly selecting resources. When the speed of the terminal device is at a low speed for a period of time, for example, in a scenario where the handheld terminal device leaves the vehicle and walks, or uses a bicycle, etc., it can be determined in the second resource pool to determine the resources for sending PSSCH by partial listening and selecting resources and / or randomly selecting resources. The target states and application scenarios are not exhaustive here, and the specific target states need to be flexibly determined based on the actual situation and environmental conditions.

[0237] The following describes in detail the data transmission method used in the embodiment of the present application with the network device as the execution subject. Figure 6 , Figure 6 This is a schematic diagram of an embodiment of a method for data transmission in an embodiment of the present application. The method for data transmission includes the following steps.

[0238] S401: A network device sends resource pool configuration information.

[0239] In this embodiment, sending resource pool configuration information specifically refers to the network device sending resource pool configuration information to the first terminal device. The resource pool configuration information includes first resource pool information and second resource pool information. The first resource pool information is used to indicate the first resource pool, and the second resource pool information is used to indicate the second resource pool. The first resource pool and the second resource pool are resource pools of different types. The first resource pool is a collection of first time-frequency resources, and the second resource pool is a collection of second time-frequency resources. The resource determination method of the first resource pool includes full listening, and the resource determination method of the second resource pool includes partial listening selection and random selection. Secondly, the resource pool configuration information can also be used to indicate N sending resource pools and P receiving resource pools. Since the sending resource pool is used to send SL and the receiving resource pool is used to receive SL, the total number of configured receiving resource pools is greater than or equal to the total number of configured sending resource pools, that is, P is greater than or equal to N, so that the first terminal device can receive data sent from different sending resource pools as much as possible. It should be understood that in actual applications, the resource determination method of the first resource pool can also include partial listening selection and random selection, which is not specifically limited here.

[0240] Specifically, after the first terminal device receives the resource pool configuration information, it can also obtain the first priority value corresponding to the PSSCH, and then determine the size of the first priority value and the first priority threshold. When the first priority value is less than the first priority threshold, the first terminal device determines to send PSSCH in the first resource pool, or when the first priority value is greater than or equal to the first priority threshold, it determines to partially listen in the second resource pool to select the resource determination method and / or randomly select the resource determination method to determine the resource for sending PSSCH. The first priority threshold can be provided by the resource pool configuration information, or provided by the first resource pool information.

[0241] Optionally, the first resource pool information is also used to indicate random selection configuration information, and the random selection configuration information includes enabling a random selection resource determination method, or prohibiting enabling a random selection resource determination method. The first terminal device receives the first resource pool information indicating the random selection configuration information, and can determine the resources for sending PSSCH in different resource pools in a randomly selected resource determination method under different conditions. The specific method for determining the resources for sending PSSCH in the first resource pool in a randomly selected resource determination method, and the method for determining the resources for sending PSSCH in the second resource pool in a randomly selected resource determination method have been introduced in the present embodiment introduced with the first terminal device as the execution body, and will not be repeated here.

[0242] Optionally, the first resource pool information is also used to indicate preemption information, and the preemption information includes a resource determination method that enables preemption, or a resource determination method that prohibits preemption. The first terminal device receives the first resource pool information indicating the preemption information, and can also determine the resources for sending PSSCH in different resource pools in a randomly selected resource determination method under different conditions. At this time, the preemption information can also provide a first priority threshold. The specific method of determining the resources for sending PSSCH in the first resource pool in a randomly selected resource determination method, and the method of determining the resources for sending PSSCH in the second resource pool in a randomly selected resource determination method have been introduced in the present embodiment introduced with the first terminal device as the execution body, and will not be repeated here.

[0243] Optionally, the first resource pool information is also used to indicate partial listening selection configuration information, and the partial listening selection configuration information includes a resource determination method for enabling partial listening selection, or a resource determination method for prohibiting partial listening selection. The first terminal device receives the first resource pool information indicating the partial listening selection configuration information, and can determine the resources for sending PSSCH in different resource pools in a resource determination method for partial listening selection under different conditions. The specific method for determining the resources for sending PSSCH in the first resource pool in a resource determination method for partial listening selection, and the method for determining the resources for sending PSSCH in the second resource pool in a resource determination method for partial listening selection have been introduced in the present embodiment introduced with the first terminal device as the execution body, and will not be repeated here.

[0244] Optionally, the first resource pool information is also used to indicate preemption information, and the preemption information includes a resource determination method for enabling preemption, or a resource determination method for prohibiting preemption. The first terminal device receives the first resource pool information indicating the preemption information, and can also determine the resources for sending PSSCH in different resource pools in a resource determination method selected by partial listening under different conditions. The specific method for determining the resources for sending PSSCH in the first resource pool in a resource determination method selected by partial listening, and the method for determining the resources for sending PSSCH in the second resource pool in a resource determination method selected by partial listening have been introduced in the present embodiment introduced with the first terminal device as the execution body, and will not be repeated here.

[0245] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of method. It can be understood that in order to realize the above functions, the data transmission device and the configuration device of the resource pool configuration information include hardware structures and / or software modules corresponding to the execution of each function.
