[0006] Optionally, when the periodic type of the service is aperiodic, the first resource pool is the dedicated resource pool for random resource selection.

[0007] Optionally, when the periodic type of the service is periodic, the first resource pool is the mixed resource pool or the dedicated resource pool for random resource selection.

[0008] Optionally, when the first resource pool is the mixed resource pool, the method further includes: reserving resources at a preset time interval.

[0009] Optionally, the determining the first resource pool according to the periodic type of the service includes: determining the first resource pool according to the periodic type of the service and the transmission priority of the service.

[0010] Optionally, determining the first resource pool according to the periodic type of the service and the transmission priority of the service includes: when the transmission priority of the service is greater than or equal to a preset threshold and the periodic type of the service is periodic, selecting the dedicated resource pool for random resource selection or the hybrid resource pool as the first resource pool; when the transmission priority of the service is less than the preset threshold and the periodic type of the service is periodic, selecting the dedicated resource pool for random resource selection as the first resource pool.

[0011] Optionally, reserving resources at a preset time interval includes: taking the time domain position of the resources randomly selected from the first resource pool as the starting position, and determining a plurality of resources in sequence at the preset time interval.

[0012] Optionally, determining the first resource pool according to the periodic type of the service includes: determining a second resource pool according to the periodic type of the service, where the second resource pool includes at least one of the hybrid resource pools and / or at least one of the dedicated resource pools for random resource selection; selecting the first resource pool from the second resource pool.

[0013] An embodiment of the present invention also discloses a transmission resource determination device, including: a resource pool determination module, configured to determine a first resource pool according to the periodic type of a service when the resource selection mechanism is random resource selection, where the first resource pool is a hybrid resource pool or a dedicated resource pool for random resource selection, the hybrid resource pool refers to a resource pool that supports multiple resource selection mechanisms, the multiple resource selection mechanisms include random resource selection and sensing resource selection, and the dedicated resource pool for random resource selection only supports random resource selection; a resource selection module, configured to perform random resource selection in the first resource pool.

[0014] An embodiment of the present invention also discloses a computer-readable storage medium, on which a computer program is stored, and when the computer program is run by a processor, the steps of the transmission resource determination method are executed.

[0015] An embodiment of the present invention also discloses a transmission resource determination device, including a memory and a processor, where a computer program that can run on the processor is stored on the memory, and when the processor runs the computer program, the steps of the transmission resource determination method are executed.

[0016] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0017] In the technical solution of the present invention, for a user equipment with a random resource selection mechanism, it can determine a first resource pool according to the periodic type of the service. The first resource pool is a hybrid resource pool or a dedicated resource pool for random resource selection. By selecting different types of resource pools for random resource selection according to the period of the service, the service requirements of different services can be met, and the flexibility of transmission can be improved.

[0018] Further, when the periodic type of the service is aperiodic, the first resource pool is the dedicated resource pool for random resource selection. Since the data of services with an aperiodic periodic type is bursty and unpredictable, by enabling the user equipment with a random resource selection mechanism to select resources in a dedicated resource pool, the collision of resource selection between this user equipment and the user equipment with a non-random resource selection mechanism can be avoided, and the transmission reliability can be improved.

[0019] Further, when the first resource pool is the hybrid resource pool and the periodic type of the service is periodic, resources are reserved at a preset time interval. Since both the user equipment with a random resource selection mechanism and the user equipment with a non-random resource selection mechanism can select resources in the hybrid resource pool, the user equipment with a random resource selection mechanism can make the user equipment with a non-random resource selection mechanism perceive the resources by reserving resources, thereby avoiding resource collision and improving transmission reliability.

[0020] Further, when the transmission priority of the service is greater than or equal to a preset threshold and the periodic type of the service is periodic, the dedicated resource pool for random resource selection or the hybrid resource pool is selected as the first resource pool; when the transmission priority of the service is less than the preset threshold and the periodic type of the service is periodic, the dedicated resource pool for random resource selection is selected as the first resource pool. In the technical solution of the present invention, the user equipment with a random resource selection mechanism uses the hybrid resource pool to select resources only when the transmission priority of the service is greater than or equal to the preset threshold, which can avoid the resource being preempted by the user equipment with a non-random resource selection mechanism during the resource preemption stage and improve the transmission reliability.

[0023] Figure 3 is a schematic structural diagram of a device for determining transmission resources according to an embodiment of the present invention. Detailed implementation manners

[0024] As described in the background art, since randomly selected UEs have different service requirements, using the same resource pool for resource selection cannot meet the requirements of UEs.

[0025] Furthermore, since randomly selected UEs do not have sensing capabilities and cannot sense that the transmission resources are preempted by other UEs, there will be a situation where low-priority randomly selected UEs are preempted by high-priority non-randomly selected UEs, resulting in transmission collisions.

[0026] In the technical solution of the present invention, for a user equipment with a random resource selection mechanism, it can determine a first resource pool according to the cycle type of the service, and the first resource pool is a mixed resource pool or a dedicated resource pool for random resource selection. By selecting different types of resource pools for random resource selection through the cycle of the service, it can meet the service requirements of different services and improve the flexibility of transmission.

[0027] The technical solution of the present invention is applicable to 5G (5th Generation) communication systems, and can also be applicable to 4G and 3G communication systems, and can also be applicable to various future new communication systems, such as 6G, 7G, etc.

[0028] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0029] Figure 1 It is a flowchart of a method for determining transmission resources according to an embodiment of the present invention.

[0030] The method for determining transmission resources according to an embodiment of the present invention can be used on the user equipment side, that is, each step of the method can be executed by the user equipment. The user equipment includes but is not limited to various appropriate terminal devices such as mobile phones, computers, and tablets.

[0031] Specifically, the method for determining transmission resources may include the following steps:

[0032] Step S101: When the resource selection mechanism is random resource selection, determine a first resource pool according to the cycle type of the service. The first resource pool is a mixed resource pool or a dedicated resource pool for random resource selection. The mixed resource pool refers to a resource pool that supports multiple resource selection mechanisms, and the multiple resource selection mechanisms include random resource selection and sensing resource selection. The dedicated resource pool for random resource selection refers to a resource pool that only supports random resource selection;

[0033] Step S102: Perform random resource selection in the first resource pool.

[0034] It should be noted that the sequence numbers of the steps in this embodiment do not represent the limitation of the execution order of each step.

[0035] It can be understood that in specific implementation, the transmission resource determination method can be implemented in the form of a software program, and this software program runs in a processor integrated inside a chip or a chip module.

[0036] The transmission resource determination method of the embodiment of the present invention can be used in a V2X communication scenario, and can also be used in any other implementable scenario that requires resource selection. The embodiment of the present invention does not limit this.

[0037] In specific implementation, for a user equipment whose resource selection mechanism is random resource selection, it can determine a first resource pool according to the periodic type of the service for random resource selection. Wherein, the first resource pool is a mixed resource pool or a dedicated resource pool for random resource selection. The mixed resource pool refers to a resource pool that supports multiple resource selection mechanisms, and the multiple resource selection mechanisms include random resource selection and sensing resource selection. The dedicated resource pool for random resource selection refers to a resource pool that only supports random resource selection. Specifically, the mixed resource pool and the dedicated resource pool for random resource selection can be pre-configured for the user equipment by a network-side device, such as a base station.

[0038] Specifically, sensing resource selection includes partial sensing resource selection and full sensing resource selection. Full sensing resource selection means continuous resource sensing, and partial sensing resource selection means resource sensing in some time units. The specific implementation manners of partial sensing resource selection and full sensing resource selection can refer to the prior art and will not be elaborated here.

[0039] It should be noted that the base station can also configure other types of resource pools for the user equipment, such as a dedicated resource pool for full sensing. The dedicated resource pool for full sensing refers to a resource pool that only supports full sensing resource selection. The embodiment of the present invention does not limit this.

[0040] In specific implementation, the periodic type of the service can include periodic and aperiodic. That is to say, the services executed by this user equipment include periodic services and aperiodic services. Specifically, the data of periodic services is generated periodically, and the data of aperiodic services is generated suddenly.

[0041] Services with different periodic types may have different requirements for resources. By determining the resource pool according to the different periodic types of the services in the embodiment of the present invention, the requirements of different services can be met.

[0042] In a non-limiting embodiment, Figure 1The step S101 shown may include the following steps: determining a second resource pool according to the periodic type of the service, where the second resource pool includes at least one of the hybrid resource pools and / or at least one of the dedicated resource pools for random resource selection; and selecting the first resource pool from the second resource pool.

[0043] In this embodiment, the second resource pool represents the resource pool available for the service of the current periodic type, and the number of second resource pools may be one or multiple. The first resource pool is selected from the second resource pools.

[0044] Specifically, when the periodic type of the service is aperiodic, the second resource pool is at least one dedicated resource pool for random resource selection.

[0045] Specifically, when the periodic type of the service is periodic, the second resource pool may be at least one dedicated resource pool for random resource selection, or at least one hybrid resource pool, or at least one hybrid resource pool and at least one dedicated resource pool for random resource selection.

[0046] In the current V2X communication scenario, re-selection of pre-empted resources that have been reserved is supported. For a certain reserved resource within slot m, pre-emption detection is performed at least at m - T3. The detection process performs a complete sensing process to form a candidate resource set. If the resource is not in the candidate resource set and meets the pre-emption priority condition, then the resource selection process is triggered to re-select the resource from the candidates. The pre-emption priority condition is that the priority of the sensing UE is higher than that of the sensing UE. That is to say, resource collision problems may occur during the pre-emption phase, that is, the randomly selected UE with a lower priority cannot sense that the resource has been pre-empted by the sensing-capable UE with a higher priority, and thus cannot perform resource re-selection, so transmission collisions will occur.

[0047] To avoid resource collisions, the embodiment of the present invention designs a corresponding resource selection mechanism for user equipment with a random resource selection mechanism.

[0048] In a specific embodiment, when the periodic type of the service is aperiodic, the first resource pool is the dedicated resource pool for random resource selection.

[0049] In this embodiment, since the data of the aperiodic traffic is bursty, unpredictable, and not suitable for periodic resource reservation, when the resource selection mechanism is random resource selection and the traffic cycle type is aperiodic, by enabling the user equipment with the random resource selection mechanism to select resources in a dedicated resource pool, while the user equipment with the non-random resource selection mechanism will select resources in other resource pools, it is possible to avoid resource selection collisions between this user equipment and the user equipment with the non-random resource selection mechanism, and improve transmission reliability.

[0050] In a specific embodiment, when the traffic cycle type is periodic, the first resource pool is the dedicated resource pool for random resource selection.

[0051] In this embodiment, although the data of the periodic traffic is generated periodically, it is also possible to enable the user equipment with the random resource selection mechanism to select resources in a dedicated resource pool, while the user equipment with the non-random resource selection mechanism will select resources in other resource pools, avoiding resource selection collisions between this user equipment and the user equipment with the non-random resource selection mechanism.

[0052] In another specific embodiment, when the traffic cycle type is periodic, the first resource pool is the hybrid resource pool. When the user equipment performs random resource selection in the first resource pool, resources are reserved at a preset time interval.

[0053] In this embodiment, the user equipment selects the resource pool based on the traffic type, which can ensure that the traffic of the UEs performing random resource selection in the hybrid resource pool is periodic. Then, by restricting the UEs to perform periodic resource reservation, it can ensure that other UEs with sensing capabilities can sense that the resources are occupied when the resources appear periodically in front, and thus avoid them.

[0054] Further, reserving resources at a preset time interval specifically means that, starting from the time domain position of the resource randomly selected in the first resource pool, with the preset time interval as the time interval, multiple resources are determined in sequence.

[0055] Specifically, refer to Figure 2 , select the first resource s1 in the hybrid resource pool, and determine subsequent multiple reserved resources s2, s3, and s4 at intervals of the preset time interval T1. By reserving resources, other UEs with sensing capabilities can sense resources s2, s3, and s4, and thus avoid them, avoiding resource collisions.

[0056] In another specific embodiment, the first resource pool is determined according to the traffic cycle type and the traffic transmission priority.

[0057] In specific implementation, the second resource pool can be determined first according to the cycle type of the service, and then the first resource pool can be determined in the second resource pool according to the transmission priority of the service.

[0058] Specifically, the transmission priority (Priority) of the service can be pre-configured. For example, there are multiple levels of the transmission priority of the service, and the lower the level, the higher the priority. For example, there are 8 values (1 - 8) for the transmission priority corresponding to different transmission priorities. When the value is 1, the priority is the highest.

[0059] Furthermore, when the transmission priority of the service is greater than or equal to a preset threshold and the cycle type of the service is periodic, the random resource selection dedicated resource pool or the hybrid resource pool is selected as the first resource pool; when the transmission priority of the service is less than the preset threshold and the cycle type of the service is periodic, the random resource selection dedicated resource pool is selected as the first resource pool.

[0060] In a specific implementation manner of selecting the first resource pool in the second resource pool, as described above, when the cycle type of the service is periodic, the second resource pool includes at least one hybrid resource pool and at least one random resource selection dedicated resource pool. Thus, when the transmission priority of the service is greater than or equal to the preset threshold, the hybrid resource pool is selected as the first resource pool in the second resource pool; when the transmission priority of the service is less than the preset threshold, the random resource selection dedicated resource pool is selected as the first resource pool in the second resource pool.

[0061] In another specific implementation manner of selecting the first resource pool in the second resource pool, when the cycle type of the service is periodic, the second resource pool includes at least one hybrid resource pool and at least one random resource selection dedicated resource pool. The UE can randomly select a resource pool from the second resource pool as the first resource pool. For example, the UE randomly selects the hybrid resource pool as the first resource pool, or the UE randomly selects the random resource selection dedicated resource pool as the first resource pool.

[0062] It should be noted that the so-called transmission priority greater than or equal to the preset threshold in the embodiments of the present invention can also be replaced with the transmission priority greater than the preset threshold, and correspondingly, the transmission priority less than the preset threshold is replaced with less than or equal to. That is to say, when the transmission priority of the service is greater than the preset threshold, the hybrid resource pool is selected as the first resource pool in the second resource pool; when the transmission priority of the service is less than or equal to the preset threshold, the random resource selection dedicated resource pool is selected as the first resource pool in the second resource pool.

[0063] In the embodiments of the present invention, by selecting a resource pool according to the periodic type of a service, it can be ensured that the services of UEs performing random resource selection in a hybrid resource pool are all periodic. Then, by restricting UEs performing random resource selection of lower-priority periodic services to use a dedicated resource pool for random resource selection, and UEs performing random resource selection of higher-priority periodic services to use a hybrid resource pool, the transmission of higher-priority periodic services of UEs performing random resource selection will not be preempted during resource preemption, thereby avoiding the resource selection mechanism being preempted by UEs with sensing capabilities of higher priority in the hybrid resource pool for UEs performing random resource selection, and improving the transmission reliability of the V2X communication system.

[0064] Please refer to Figure 3 , embodiments of the present invention also disclose a transmission resource determination device 30, and the transmission resource determination device may include:

[0066] A resource selection module 302, configured to perform random resource selection in the selected resource pool in the first resource pool.

[0067] In the embodiments of the present invention, for a user equipment with a random resource selection mechanism, it can determine a first resource pool according to the periodic type of a service, and the first resource pool is a hybrid resource pool or a dedicated resource pool for random resource selection. By selecting different types of resource pools according to the period of the service for random resource selection, it can meet the service requirements of different services and improve the flexibility of transmission.

[0068] In a non-limiting embodiment of the present invention, when the periodic type of the service is aperiodic, the first resource pool is the dedicated resource pool for random resource selection.

[0069] In a non-limiting embodiment of the present invention, when the periodic type of the service is periodic, the first resource pool is the hybrid resource pool or the dedicated resource pool for random resource selection. Further, when the first resource pool is the hybrid resource pool, resources are reserved at a preset time interval.

[0070] In a non-limiting embodiment of the present invention, the first resource pool is determined according to the periodic type of the service and the transmission priority of the service. When the transmission priority of the service is greater than or equal to a preset threshold and the periodic type of the service is periodic, the dedicated resource pool for random resource selection or the hybrid resource pool is selected as the first resource pool; when the transmission priority of the service is less than the preset threshold and the periodic type of the service is periodic, the dedicated resource pool for random resource selection is selected as the first resource pool.
