Description

A V2X resource configuration method, device and related equipment

technical field

The present invention relates to the field of wireless communication technologies, and in particular to a V2X resource configuration method, device and related equipment.

Background technique

In the Long Term Evolution (LTE, Long Term Evolution) system, a side link (sidelink) is defined to support direct communication between user equipment (User Equipment, UE). The V2X (Vehicle to Everything, Vehicle-to-everything) communication (hereinafter referred to as: PC5-based LTE-V2X), can realize vehicle-to-vehicle (V2V, Vehicle to Vehicle), vehicle-to-road (V2I, Vehicle to Infrastructure) and vehicle-to-person (V2P, Vehicle to Pedestrian) direct communication between.

The PC5-based LTE-V2X will adopt the resource allocation mode (mode 1) scheduled by the base station and the resource allocation mode (mode 2) independently selected by the UE. These two resource allocation modes exist independently.

For example, if the mode 1 resource allocation mode is adopted alone, LTE-V2X will introduce a semi-persistent scheduling method to adapt to periodic services in V2X services. At the same time, it will support cross-carrier scheduling to support the base station to send scheduling signaling to schedule V2X transmission on the V2X dedicated spectrum (such as 5.9GHz) through the authorized spectrum (such as 2.6GHz). In the resource allocation mode of mode 1, the vehicle and the eNodeB are in the connected state, and each time the vehicle performs V2V transmission, it must first apply for resources from the eNodeB.

In addition, the mode 2 resource allocation mode is adopted alone, and its congestion control mechanism is: the UE can automatically reduce its own service transmission frequency, thereby reducing the system load. However, this mechanism is independently completed by a single UE, and it is difficult to quickly respond to high-priority services, for example, services that require high real-time performance and transmission frequency.

However, when the resource allocation mode scheduled by the base station and the resource allocation mode independently selected by the UE exist at the same time, how to coordinate the resource allocation of these two modes is not involved in the prior art.

The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention, and in the absence of conflict, the present invention The embodiments and the features in the embodiments can be combined with each other.

Embodiment one

As shown in FIG. 1a, it is a schematic flowchart of a method for configuring network-side V2X resources provided by Embodiment 1 of the present invention, which may include the following steps:

S11. Send configuration signaling to the user equipment UE, where the configuration signaling includes first resource pool configuration information used to indicate the first resource pool and second resource pool configuration information used to indicate the second resource pool.

Preferably, before performing step S11, the network side also needs to predetermine at least one first resource pool and at least one second resource pool.

During specific implementation, the transmission resources in the first resource pool are used for vehicle-to-everything V2X direct communication in the first transmission mode, and the transmission resources in the second resource pool are used for the second transmission mode or for the first transmission mode. mode and V2X direct communication of the second transmission mode.

For details, refer to the schematic distribution diagram of the first resource pool and the second resource pool shown in FIG. 1b. The resources marked with "1" in the figure represent the transmission resources used for V2X direct communication in the first transmission mode in the first resource pool; the resources marked with "2" represent the V2X direct communication used in the second transmission mode in the second resource pool. Transmission resources for direct communication; resources marked with "3" represent a shared resource pool, where the transmission resources in the shared resource pool include transmissions for V2X direct communication in the first transmission mode and the second transmission mode in the second resource pool resource.

Optionally, the first transmission mode is 3GPP LTE Release 14 version or 3GPP LTE (3rdGeneration Partnership Project Long Time Evolution, 3rd Generation Partnership Project Long Time Evolution technology) Release 14 and V2X direct communication defined in 3GPP LTE Release 15 mode, the second transmission mode is a V2X direct communication mode defined in 3GPP LTE Release 15 or later versions of 3GPP LTE Release 15.

Preferably, the first transmission mode may also be a V2X direct communication mode based on base station scheduling, and the second transmission mode may also be a V2X direct communication mode without base station scheduling.

After the network side determines at least one first resource pool and at least one second resource pool, when the V2X direct communication of the first transmission mode and the second transmission mode exist at the same time, the first transmission mode uses the first resource pool, and the second transmission mode uses the first resource pool. The transmission mode uses the second resource pool, so that information transmission between UEs using different transmission modes does not affect each other.

During specific implementation, in order to enable UE (User Equipment, user equipment) to select corresponding resources for transmission according to the configuration of the first resource pool and the second resource pool on the network side, the network side determines at least one first resource pool and at least one second resource pool After two resource pools, configuration signaling needs to be sent to the UE or pre-configured in the UE. The configuration signaling includes the first resource pool configuration information used to indicate the first resource pool and the configuration information used to indicate the second resource pool. Based on the second resource pool configuration information of the resource pool, after receiving the configuration signaling, the UE can perform V2X direct communication according to the configuration information included in the configuration signaling.

Preferably, the configuration signaling includes first resource pool configuration information for indicating each first resource pool and second resource pool configuration information for indicating each second resource pool.

Specifically, the specific process of allocating resources for the UE in the resource allocation mode scheduled by the base station is shown in steps S12 and S13:

S12. Obtain the resource scheduling information of the UE, wherein the resource scheduling information includes at least one of the following: the service priority of the current service of the UE, and/or the congestion of the first resource pool and/or the second resource pool level information.

Wherein, the service priority is determined according to service quality (QoS) of the service. And the congestion level information of the first resource pool and/or the second resource pool may be information reflecting the congestion degree of one or more first resource pools and/or the second resource pool. Specifically, each first resource pool or second resource pool has a congestion level information; or each type of resource pool has a congestion level information, that is, all the first resource pools in Figure 1b belong to one category and have a congestion level information. level information; and all second resource pools belong to one category and have a congestion level information. Alternatively, each group of resource pools may have a piece of congestion level information, that is, the first resource pool or the second resource pool is divided into several groups, and each of these groups has a piece of congestion level information. Wherein, the congestion level information is obtained by UE measurement on the corresponding resource pool or resource pool set, and the measured parameter may be a subchannel whose received power or received energy exceeds a certain threshold in the corresponding resource pool or resource pool set or the number or proportion of subchannels occupied by the UE in the corresponding resource pool or resource pool set, the congestion level information of the resource pool or resource pool set can be obtained by measuring these parameters respectively, or these parameters A comprehensive operation is performed to obtain the congestion level information of the resource pool or resource pool set, wherein the obtained congestion level information is different according to the measured parameters. Wherein, the congestion level information of the first or second resource pool measures the amount of transmission resources occupied by the UE on the resource pool. , so that the occupied resources reach a certain value, it means that the resource pool is highly congested.

During specific implementation, in the resource allocation mode scheduled by the base station, when the network side obtains UE resource scheduling information, the following two implementation modes can be adopted:

Method 1: Receive the V2X direct communication request sent by the UE

Specifically, the resource scheduling information is carried in the V2X direct communication request.

Method 2: Receive the resource scheduling information reported by the UE triggered by the network side

Wherein, the network side triggers the UE to report the resource scheduling information according to at least one of the following information: geographic location information of the UE, moving speed, and vehicle type of a vehicle carrying the UE. Specifically, the UE may use real-time reporting, periodic reporting, or report the geographical location information of the UE, the current moving speed, and the vehicle type of the vehicle carrying the UE, etc. under a specific trigger event, and then the network side reports the UE information according to the UE report. Geographical location information, current moving speed, vehicle type, etc., to determine whether to trigger the UE to report resource scheduling information. Wherein, the specific trigger event may be a severe congestion event or a sudden traffic accident.

Preferably, the UE may report the resource scheduling information through RRC (Radio Resource Control, radio resource control) signaling. It should be noted that the congestion level information of the first resource pool and/or the second resource pool in the resource scheduling information may be reported by the UE, or may be reported by other UEs or obtained by the network side through other means, For example, the network side can detect the usage of transmission resources of each first resource pool or second resource pool in real time or periodically, so as to obtain the congestion level information of each resource pool.

Preferably, when the network side determines at least one first resource pool and at least one second resource pool, Embodiment 1 of the present invention provides two methods for determination, for example: at least one first resource pool can be determined according to resource scheduling information and at least one second resource pool, or determine at least one first resource pool and at least one second resource pool according to a preset method, which can determine at least one first resource pool and at least one second resource pool in a user-defined manner A secondary resource pool.

S13. Send resource scheduling signaling to the UE, where the resource scheduling signaling includes transmission resources for V2X direct communication.

Preferably, the method further includes: determining, according to the obtained resource scheduling information, to allocate transmission resources for the UE to perform V2X direct communication when a preset resource allocation condition is satisfied.

Specifically, when the resource scheduling information only includes the service priority of the UE's current service, the network side only needs to determine whether the service priority belongs to the pre-configured service priority set according to the service priority information, and if so, then Determine that the preset resource allocation condition is met, and send resource scheduling signaling to the UE; otherwise, determine that the preset resource allocation condition is not met. When the resource scheduling information only includes the congestion level information of the first resource pool and/or the second resource pool, it is only judged based on the congestion level information whether the preset resource allocation condition is satisfied, and if so, the UE is allocated for Transmission resources for V2X direct communication. When the resource scheduling information includes the service priority of the currently ongoing business and the congestion level information of the first resource pool and the second resource pool, it can first be judged according to the congestion level information whether the preset resource allocation condition is met, and if so, It is then judged whether the service priority of the service satisfies the preset priority set, and if both are satisfied, the transmission resource for V2X direct communication is preferentially allocated to the UE. Of course, there are other combinations for judging whether to allocate transmission resources for V2X direct communication to the UE, which will not be listed here.

It should be noted that, before sending the resource scheduling signaling to the UE, it also includes:

Notifying the UE of the carrier information of the carrier used to transmit the resource scheduling signaling.

Wherein, the resource scheduling signaling is DCI (Downlink Congtrol Indication, downlink control information).

In order to coordinate the resource allocation mode scheduled by the base station and the resource allocation mode of the resource allocation mode independently selected by the UE, the network side uses dynamic scheduling signaling to perform resource scheduling for the UE. Therefore, before sending the resource scheduling signaling to the UE, the UE needs to be notified of the carrier information of the carrier used to transmit the resource scheduling signaling. The carrier information can be used for cross-carrier indication, and the network side schedules the sidelink through different downlink carriers. (Side Link) Different first resource pools on carriers. Specifically, as shown in FIG. 2a , specifically, the network side may send the dynamic scheduling signaling to the UE through the downlink carrier 1, and then send the resource scheduling signaling to the UE through the downlink carrier 2. So that the UE receives the resource scheduling signaling at the corresponding carrier.

Specifically, the resource scheduling signaling also includes the identification information of the network side base station or the identification information of the cell or the identification information of the operator, and the network side can use different base stations, or cells or operators for different first resource pools For resource scheduling, refer to the schematic diagram of base station, or cell or operator resource distribution shown in FIG. 2b.

Specifically, the resource scheduling signaling further includes at least one of the following information: modulation and coding scheme MCS of data information, transport block size TBS, number of transmissions, power control information, and a pre-configured service priority set.

During specific implementation, Embodiment 1 of the present invention provides four methods for judging whether the preset resource allocation conditions are satisfied according to the obtained resource scheduling information, which are described in detail below:

the first method:

As shown in FIG. 3 , it is a schematic flowchart of the implementation of the first method for judging whether a preset resource allocation condition is met in the V2X resource scheduling method provided by Embodiment 1 of the present invention, which may include the following steps:

S31. Judging whether the congestion level of the second resource pool exceeds the preset first congestion level threshold according to the congestion level information of the second resource pool, and if the judgment result is yes, perform step S33; otherwise, perform step S34 .

S32. According to the congestion level information of the first resource pool and the second resource pool, determine whether the difference between the congestion levels of the second resource pool and the first resource pool exceeds a preset first congestion level threshold , if the judgment result is yes, execute step S33; otherwise, execute step S34.

Specifically, when determining the congestion level of the first resource pool or the second resource pool according to the congestion level information of the first resource pool or the second resource pool in steps S31 and S32, the parameter measured in step S21 is used as the received power Or the ratio of the number of subchannels whose received energy exceeds a certain threshold to all subchannels in the resource pool is described as an example, and then the network side can find the corresponding relationship table between the congestion level information and the preset congestion level. The congestion level corresponding to the congestion level information, and the correspondence table between the congestion level information and the congestion level can be referred to in Table 1:

Table 1

Congestion Level Information congestion level 80%～100% Level 5 60%～80% level 4 35%～60% Level 3 10%～35% level 2 0～10% Level 1

The higher the value of the congestion level in Table 1, the more congested it is. It should be noted that when the measurement parameter is other values such as the number or proportion of occupied sub-channels, the method for determining the congestion level may also be different, and the embodiment of the present invention is only a method for determining the congestion level proposed to facilitate the understanding of the present invention. Obviously, there are other determination methods for other measurement parameters, and any method in the prior art for determining the congestion level in the present invention is applicable to the present invention.

During specific implementation, in order to avoid the situation where the UE occupies too many transmission resources in the first resource pool when the resources in the second resource pool are sufficient, the network side needs to determine the second Whether the congestion level of the resource pool exceeds the preset first preset level threshold, or whether the difference between the congestion levels of the second resource pool and the first resource pool exceeds the preset first congestion level threshold; if so, Then step S33 is executed, and it means that the second resource pool does not have enough resources, and the network side allocates transmission resources for V2X direct communication to the UE from the first resource pool. If not, execute step S34, indicating that the current resources in the second resource pool can meet the UE's V2X direct communication request, so the network side will refuse to allocate resources in the first resource pool for the UE, and the UE performs the second transmission mode. The V2X direct communication autonomously acquires transmission resources from the second resource pool for performing V2X direct communication. This can not only ensure the full utilization of the second resource pool, but also prevent the resources of the first resource pool from being used in large quantities by ordinary vehicles, so as to reserve enough resources in the first resource pool for special vehicles or large-scale accidents. , so that the network side performs resource scheduling for some vehicles behind the special vehicle.

It should be noted that steps S31 and S32 are not sequential, step S31 can be executed first, and then step S32 can be executed; step S32 can also be executed first, and then step S31 can be executed; or if it is determined that step S31 is satisfied, step S33 can be executed directly , it is not necessary to execute the judgment process of step S32; or if it is determined that step S32 is satisfied, then directly execute step S33 without further execution of the judgment process of step S31, which is not limited in this embodiment of the present invention.

During specific implementation, the first congestion level threshold is determined according to service priorities, and the network side may set different first congestion level thresholds according to different service priorities.

S33. Determine that a preset resource allocation condition is met.

S34. Determine that the preset resource allocation condition is not satisfied.

The second method:

As shown in FIG. 4 , it is a schematic diagram of the implementation flow of the second method for judging whether a preset resource allocation condition is met in the V2X resource scheduling method provided by Embodiment 1 of the present invention, which may include the following steps:

S41. Judging whether the congestion level of the first resource pool exceeds a preset second congestion level threshold according to the congestion level information of the first resource pool, and if the judgment result is yes, perform step S42; otherwise, perform step S43 .

During specific implementation, when allocating transmission resources for the UE, the network side also needs to judge whether the current first resource pool is in a congested state, and the specific judgment process is the content in step S41. If there is congestion, the network side cannot currently allocate resources in the first resource pool to the UE, and further judgment is required, that is, step S42 is performed. If it is determined that the resources in the first resource pool are sufficient, it is determined that transmission resources for V2X direct communication can be allocated to the UE from the current first resource pool, that is, step S43 is performed.

Preferably, the network side can set different second congestion level thresholds according to different service priorities.

S42. Judging whether the service priority of the service currently being performed by the UE belongs to a pre-configured service priority set, if the judgment result is yes, perform step S43; otherwise, perform step S44.

During specific implementation, when it is determined in step S41 that the current congestion level of the first resource pool exceeds the second congestion level threshold, it is necessary to further determine whether the service priority of the UE's current ongoing service belongs to the pre-configured priority set, if If it belongs to, it indicates that the ongoing service of the UE is relatively important, and the network side needs to allocate resources in the first resource pool for the UE, but it has been determined according to step S41 that the resources in the current first resource pool are insufficient. Therefore, in Before allocating transmission resources for the UE, it also includes:

According to the service priorities reported by other UEs except the UE, reduce the number of transmission resources allocated to UEs whose service priorities do not belong to the service priority set.

During specific implementation, suppose that the current UE and other 9 UEs send V2X direct communication requests at the same time. According to the reported service priority, it is determined that the service priority of these 10 UEs belongs to the preset service priority set. If the current UE belongs to the service priority set and the other 9 UEs partly belong to the service priority set, then the network side will When allocating resources for a UE, the number of resources allocated to some UEs whose service priority does not belong to the service priority set can be reduced, so as to ensure that sufficient resources are allocated to the UE, and the V2X direct communication of the UE can reach the receiver in time.

Preferably, the network side can also determine the UE corresponding to the service with the lowest service priority from the preset service priority set, and then reduce the number of transmission resources allocated to the UE.

During specific implementation, if it is determined that the service priority of the UE belongs to the preset service priority set, and the service priority of the UE is relatively high, the network side can determine the service corresponding to the service with the lowest service priority from the service priority set Then reduce the number of transmission resources allocated to the UE corresponding to the service with the lowest service priority, and allocate sufficient transmission resources for the UE from the first resource pool, so as to ensure that the UE corresponding to the high-priority service can use sufficient transmission resources resources for V2X direct communication.

S43. Determine that a preset resource allocation condition is met.

S44. Determine that the preset resource allocation condition is not met.

The third method:

During specific implementation, the resource scheduling information also includes the moving speed and geographic location information of the UE; and

As shown in FIG. 5 , it is a schematic flowchart of the implementation of the third method for judging whether the preset resource allocation condition is met in the V2X resource scheduling method provided by Embodiment 1 of the present invention, which may include the following steps:

S51. According to the acquired moving speed of the UE and moving speeds of other UEs except the UE, determine that the moving speed is lower than a preset moving speed threshold.

S52. According to the acquired geographic location information of the UE and geographic location information of other UEs except the UE, determine a set of UEs whose distances between each other are not greater than a preset distance threshold.

S53. Randomly select UEs for which transmission resources are allocated from the UE set to form a UE subset.

S54. Determine whether the UE belongs to the UE subset, and if so, perform step S55; otherwise, perform step S56.

During specific implementation, the network side can determine the road condition of the road on which the UE is currently driving according to the UE's moving speed and geographic location information reported by the UE in real time or periodically or under a specific trigger event, and according to the UE's geographic location information and geographical location information of UEs other than the UE to determine the distance between each other. For multiple UEs whose moving speed is lower than the preset moving speed threshold and the distance between each other is not greater than the preset distance threshold, the network side can determine that the intersection where the vehicle where the current UE is driving is currently relatively congested, and the distance between the multiple UEs is relatively close. If the transmission resources in the first resource pool are allocated to each UE, the transmission resources in the first resource pool will be wasted, and in this road condition, some UEs can represent vehicle driving information of multiple UEs. Therefore, in order to avoid wasting the transmission resources of the first resource pool, reduce the congestion level of the first resource pool, and make the transmission distance of the communication message longer, some UEs in the plurality of UEs can be allocated transmission resources in the first resource pool. resource. The specific method is as follows: the network side randomly selects some UEs from the UE set determined in step S52 and step S53 to form a UE subset, and then executes step S54. If it is determined that the UE belongs to the UE subset, allocate the transmission resource in the first resource pool to the UE, that is, perform step S55; otherwise, do not allocate the transmission resource in the first resource pool to the UE, that is, perform step S56 .

S55. Determine that a preset resource allocation condition is met.

S56. Determine that the preset resource allocation condition is not met.

The fourth method:

During specific implementation, the resource scheduling information also includes the vehicle type of the vehicle carrying the UE; and

As shown in FIG. 6 , it is a schematic flowchart of the implementation of the fourth method for judging whether the preset resource allocation condition is met in the V2X resource scheduling method provided by Embodiment 1 of the present invention, which may include the following steps:

S61. Determine whether the vehicle type of the vehicle carrying the UE is a preset vehicle type, and if the determination result is yes, perform step S62; otherwise, perform step S63.

During specific implementation, for special vehicles such as ambulances and fire trucks, the network side preferably allocates transmission resources in the first resource pool for them. For this reason, the UE also needs to report the described The vehicle type of the UE's vehicle. If the network side judges that the vehicle type reported by the UE belongs to the preset vehicle type according to the vehicle type reported by the UE, it will allocate enough transmission resources in the first resource pool to ensure that the information in the V2X direct communication performed by the UE Transmission reliability and transmission distance.

S62. Determine that a preset resource allocation condition is met.

S63. Determine that the preset resource allocation condition is not satisfied.

Preferably, the transmission resources used for the first transmission mode and the second transmission mode in the first resource pool and the transmission resources used for the first transmission mode and the second transmission mode in the second resource pool form a shared resource pool; and

The method also includes:

For each shared resource pool, if it is determined according to the congestion level information of the first resource pool and/or the second resource pool that the congestion level of the shared resource pool exceeds a preset third congestion level threshold, the shared resource pool is reduced.
