- This embodiment proposes an electronic device for link stability measurement in a fleet.
- 2 shows a functional block diagram of the electronic device 100.
- the electronic device 100 includes: a confirmation unit 101 configured to confirm a network structure of a fleet; and a determining unit 102 configured to determine and network structure Corresponding link stability measurement configuration, the link stability measurement configured by the receiving end device of the link determines the stability of the link according to the reception status of the transmission content.
- the confirmation unit 101 and the determination unit 102 can be implemented by one or more processing circuits, which can be implemented, for example, as a chip.
- the electronic device 100 can be located, for example, in a fleet manager.
- the fleet's network structure may include one or more of the following: Platoon Size; fleet form; architecture of network communications.
- the size of the team can be the number of team members included in the team.
- the form of the team is the organization of the team, such as a fleet of cars (as shown in the example of Figure 1) or a fleet of co-drivers that are not necessarily arranged in a row but are flexible.
- the architecture of network communication represents the way in which members of the fleet communicate, such as the composition of the link and the specific form of communication.
- A) to e) of Fig. 3 show five examples of the architecture of network communication.
- the five forms of network architecture are described separately below. However, it should be understood that the present application is not limited to the architecture of the network communication shown in FIG. 3, which is merely illustrative.
- the data transmission direction toward the fleet manager in the data link is defined as Forward Transmission, and the transmission direction away from the fleet manager is Backward Transmission; the closest in the forward transmission is defined.
- the neighbor member is called the predecessor of the current member, and the closest neighbor member in the backward transmission is called the successor of the current member.
- the fleet manager broadcasts information to the team members, and the team members send information to the fleet manager via a single-hop link, such as V3 ⁇ V1. If the same reception quality is to be achieved at the fleet manager, the closer the transmission member is to the manager, the smaller the transmission power.
- the fleet manager broadcasts information to the fleet members, and the team members use the one-way link between the adjacent fleet members to send information to the fleet manager.
- the team members establish a unidirectional link with the predecessor members, such as V3 ⁇ V2. This constitutes a one-way forward transmission link between two adjacent fleet members. Because the adjacent car is close, the link requires only a low transmit power.
- the fleet manager broadcasts information to the fleet members and there is a two-way link between adjacent fleet members. That is, on the basis of the architecture b, a unidirectional link between the fleet members and the successor members is added, for example, V2 ⁇ V3. This forms a two-way link between two adjacent fleet members.
- the advantage of this architecture is that information interaction between adjacent fleet members is easy to implement.
- the fleet is divided into a plurality of clusters, and the adjacent cluster managers exchange information through the bidirectional links, and each cluster can be configured by any one of a to d, respectively.
- This architecture is especially suitable for larger fleets.
- the number of fleet members that can be supported in LTE eV2X can be up to 19.
- the fleet can be divided into clusters according to architecture e, each cluster consisting of cluster managers and cluster members.
- the fleet manager also acts as the cluster manager of the first cluster, and the adjacent cluster managers form a bidirectional link, and the clusters can be constructed arbitrarily according to the structures a to d.
- the fleet manager only needs to manage the cluster manager, which is managed by the cluster manager.
- electronic device 100 can also be located in a cluster manager.
- the architecture of the network communication within the fleet can be set according to the size of the fleet, the communication power setting, and the like.
- the size of the team can be the number of team members included in the team. For example, when the fleet size is below the threshold N1 (such as 3), choose architecture a; when the fleet size is greater than N1 is less than N2 (such as 5), choose architecture b; when the fleet size is greater than N1 is less than N2, and need adjacent vehicles
- choose the architecture c when the fleet manager has limited transmission power, choose the architecture d; when the fleet size is greater than N2, you need to cluster first, select the cluster manager, and the network structure in each cluster can be managed by the fleet.
- the unified selection can also be selected by the cluster manager.
- the validation unit 101 and the determination unit 102 may, for example, perform respective operations in response to at least one of: a predetermined time elapses; a fleet size change; a change in information interaction requirements of the fleet members; an available network transmission resource change.
- the operations of the validation unit 101 and the determination unit 102 may be periodic and/or triggered.
- the confirmation unit 101 and the determination unit 102 perform operations in a predetermined cycle, and can determine changes in the network structure in time, such as entry and departure of fleet members, changes in the form of the fleet, changes in the network communication architecture of the fleet, such as changing from architecture a to architecture c. Wait.
- the validation unit 101 and the determination unit 102 can also operate via triggering.
- the trigger condition can be any condition that may cause a change in the network structure.
- the architecture of the fleet's network communications may change.
- the architecture of the network communication may change when the information exchange requirements of the fleet members change, for example, when the amount of information to be exchanged changes due to the state of travel or changes in the state of the surrounding traffic environment.
- a quantitative parameter of information exchange between team members may be the amount of information that a single team member needs to report in a unit time, or the amount of information that a single link needs to transmit in a unit time, which is recorded as MessageSizePerUnit, as described later,
- the parameters can be related to the network structure.
- the trigger condition may also be a change of available transmission resources notified by the network (eNB/RSU), in which case it may be necessary to change the network structure to accommodate changes in the transmission resources.
- the link configuration in the fleet may be different, and therefore, the determining unit 102 determines a corresponding link stability measurement configuration according to the network structure.
- the link stability measurement is configured for the receiving end device of the link to determine the stability of the link according to the reception status of the transmitted content. In other words, the transmission status of the link is utilized to evaluate the stability of the link.
- LTE provides two link quality measurement parameters related to the pass-through link, namely, the direct link reference signal received power (S-RSRP) and the direct link discovery reference signal received power SD-RSRP (Sidelink discovery). Reference signal received power).
- S-RSRP direct link reference signal received power
- SD-RSRP Securelink discovery reference signal received power
- the present embodiment utilizes the characteristics that the vehicles in the fleet frequently exchange information, so that the receiving vehicle can evaluate the stability of the link by monitoring the state of the receiving while receiving useful information, thereby significantly reducing the control signaling overhead.
- the stability of the link is accurately assessed with the resulting delay and required energy consumption.
- the method of the embodiment can also reduce the control signaling overhead and the required energy consumption, and improve the actual situation. Data transmission efficiency.
- the link stability measurement configuration includes, for example, a correspondence between a link transmission mode and link stability.
- the link transmission mode includes, for example, the number of times the transmission is performed on the link within a predetermined time, and the link stability includes a fixed duration such as the number or rate of successful reception within a unit time period.
- the transmission content may be signaling such as beacon, control signaling, discovery message, data, and the like.
- the link transmission mode may be an interval period during which transmission is performed on the link, and the link stability is a ratio of successful reception within a fixed period of time.
- the electronic device 100 can support two centrally controlled scheduling methods, which are determined and provided by the eNB/RSU, namely Dynamic Scheduling and Semi-persistent Scheduling (SPS).
- SPS Semi-persistent Scheduling
- dynamic scheduling has to make new scheduling decisions on each subframe, that is, the location of decision resources. This method has high flexibility in resource usage.
- the semi-persistent scheduling in addition to the resource location, also determines the scheduling interval, that is, the transmission period information.
- the resource location only needs to be sent once by the PDCCH, and the transmission period is configured through RRC signaling, that is, the scheduled resource can be used in a set period. .
- This method reduces the signaling overhead and is suitable for the cyclical transmission requirements of the data volume, such as for transmission in the fleet driving mode. Therefore, when SPS is adopted, the link stability measurement configuration will depend on the specific resource allocation method. On the other hand, when SPS is not used, the transmission may not be periodic, but the transmission resources allocated for each link will also affect the number of transmissions within a predetermined time, thereby affecting the link stability measurement configuration.
- the determining unit 102 can be configured to determine a link stability measurement configuration for the link to provide to the respective fleet member based on the transmission resources allocated for each link.
- the link stability measurement configuration is also affected by the network environment such as the number and density of surrounding vehicles, the number and frequency of surrounding vehicle messages, and the type of content being transmitted, and so on.
- the link stability may also be the number of transmissions that have not been successfully received in a fixed duration, or the ratio of the number of transmissions to the expected number of transmissions.
- the link stability may also be that the message parsed information indicates that the distance is stable for a certain period of time.
- the link stability measurement configuration may be obtained from the network, or may be determined based on a correspondence between the pre-stored network structure and the link stability measurement configuration. Furthermore, as previously described, for each link, the determining unit 102 can also adjust its link stability measurement configuration based on the allocated transmission resources.
- the transmission resources required for communication in the fleet are requested, for example, by the fleet manager to the network, such as the eNB or RSU, and the fleet resources are allocated by the fleet manager within the fleet.
- the electronic device 100 further includes a generating unit 103 configured to generate a resource allocation request based on the confirmed network structure for requesting the network to allocate network transmission resources for the fleet.
- the generating unit 103 can estimate the total amount of resource demand inside the fleet and include the estimated total amount of resource demand in the resource allocation request.
- the fleet's internal resource requirements include the dispatch of the fleet manager/fleet cluster manager and the resources required by the fleet manager/or team members to return the message.
- the generating unit 103 may perform estimation based on at least one of a network structure, a data processing mode of the forwarding node, and an amount of information to be transmitted by the fleet member in a unit time.
- the data processing mode of the forwarding node may include forwarding only or merge forwarding, and the amount of resources required by the two methods is different.
- the generating unit 103 may determine the amount of information to be transmitted by the fleet members in a unit time based on the network structure, wherein the network structure has a correspondence with the amount of information that the fleet members are to transmit in a unit time. This correspondence can be stored, for example, in advance in the storage device of the fleet manager. In this way, after confirming the network structure, the amount of information that the team members are to transmit in a unit time can be known.
- the SPS resource allocation method is suitable for communication in the fleet driving mode, and therefore, the generating unit 103 can generate one or more SPS configuration requests as resource allocation requests based on the estimated total resource demand amount.
- each vehicle or each link may require one or more SPS configurations, and the generating unit 103 may combine these SPS configurations based on considerations of reducing the amount of information required for resource allocation request signaling.
- the method of merging includes, for example, SPS configuration merging for the same transmission start time and interval period, or merging for the SPS configuration of the same spectral resource on the interval period, the result of the merging may result in one or more SPS configuration requests.
- multiple SPS configurations per vehicle or each link may be used for the interaction of different types of information.
- the resource allocation request generated by the generating unit 103 includes an identification of the network architecture of the fleet and information on the size of the fleet.
- the network can confirm the network architecture of the fleet according to the identification of the network architecture of the fleet, so that the total fleet resource demand can be estimated in combination with the fleet size. In other words, the estimate of the total demand for fleet resources is made on the network side.
- the network can allocate resources to the fleet based on the total fleet resource demand, including, for example, spectrum resources and time configuration.
- the network side can generate one or more SPS configurations.
- the electronic device 100 may further include a transceiving unit configured to transmit a resource allocation request to the network and receive a resource allocation result from the network.
- the transceiver unit can be implemented, for example, as an antenna and a corresponding transceiver circuit or the like.
- Figure 5 shows a flow diagram of information interaction between the network side and the fleet manager.
- the fleet manager triggers the confirmation of the fleet network structure in response to, for example, one of the foregoing specific conditions, and generates a resource allocation request, and sends the resource allocation request to the network (eNB/RSU), and the eNB/RSU performs resource allocation according to the request.
- a resource allocation response is sent to the fleet manager.
- the resource allocation response may further include a link stability measurement configuration corresponding to the network structure.
- the fleet manager After acquiring the transmission resources, the fleet manager allocates transmission resources within the fleet. Accordingly, as shown in FIG. 6, the electronic device 100 may further include an allocating unit 104 configured to perform allocation of transmission resources within the fleet.
- the allocation unit 104 allocates transmission resources to the fleet members according to the previously confirmed network structure and the requirements of the respective links. If the transmission resource allocated by the network is less than the total resource demand of the fleet, the confirmation unit 101 may adjust the network structure of the fleet, such as the architecture of the network communication of the fleet, based on the network transmission resources actually allocated by the network, and the allocation unit 104. The allocation of transmission resources within the fleet is based on the adjusted network structure.
- the network may also include an adjustable range of the network transmission resources when allocating network transmission resources to the fleet, and the allocating unit 104 notifies the team members of the adjustable range when allocating transmission resources to the fleet members.
- the adjustable range may include at least reducing the frequency or number of times the message is sent within a range that meets the resource allocation, or is adjusted to restore the original resource configuration.
- the adjustable range can also be set by the fleet manager.
- the reason for setting the adjustable range is that when the running state of the vehicle is stable or the link quality is good, the frequency of data exchange can be reduced, so that the required transmission resources can be reduced.
- each member of the fleet can communicate based on the assignment result while measuring the link according to the stability measurement configuration. Stability.
- Figure 7 shows a schematic diagram of the flow of information between the fleet manager and the team members.
- the fleet manager allocates transmission resources to each member (or each link) according to the network structure, and provides the resource allocation result to each member.
- the resource allocation results shown in FIG. 7 also include the above-described stability measurement configuration and/or resource adjustable range.
- the team members perform communication and link stability measurements based on the resource allocation results.
- the electronic device 100 may further include an event processing unit 105 configured to process the corresponding event based on the result of the link stability measurement.
- events include, for example, link resource configuration adjustments, interrupt handling, and the like.
- the results of the link stability measurements described herein may include link stability measurements for fleet members, as well as link stability measurements for the fleet manager or cluster manager itself.
- the electronic device 100 may further include the generating unit 103 and the allocating unit 104 shown in FIG. 6.
- the frequency of data interaction can be reduced, and vice versa.
- the adjustment of the data exchange frequency also needs to meet the frequency range required by the data type.
- the driving safety related information may have the lowest frequency limit, and the data interaction frequency adjustment result must satisfy the minimum frequency limit.
- the adjustment of the data exchange frequency also needs to meet the inherent limitation of the data update capability. For example, if the frequency of data update processed by the onboard control system by the sensor may have the highest frequency limit, the data exchange frequency adjustment result may be considered. The highest frequency limit reduces unnecessary information interaction.
- allocation unit 104 can be configured to perform a reallocation of transmission resources within the fleet based on link stability measurements.
- the resource configuration change is within the resource adjustable range, such as reducing the frequency of data interaction or restoring the original resource configuration
- the sender device of the link can adjust itself, and the receiving device of the link This adjustment can be reported to the fleet manager or cluster manager.
- the resource allocation for the link may also be adjusted accordingly by the allocation unit 104.
- resource allocation will be performed by the allocation unit 104.
- the allocating unit 104 can also perform reallocation of transmission resources within the fleet based on changes in the amount of information to be transmitted by the fleet members. For example, the amount of information that a team member is to transmit is affected by the driving state of the vehicle and the surrounding traffic conditions. In the case where the running state is unstable or the surrounding traffic state is unstable, the amount of information to be transmitted will increase, so that the allocating unit 104 is required to increase the allocation of the transmission resources of the links in which the vehicles are located.
- the event processing unit 105 will perform an interrupt processing, wherein the strategy of the link interruption processing depends on the degree of influence of the network structure and/or the interruption of the link on the fleet travel.
- Link interruption is an extreme case where link stability is degraded. For example, when the reception of the receiving end of the link fails for a continuous predetermined time, or when the reception of a predetermined number of times fails, the link is considered to be broken. Link interruptions may be caused, for example, by obstacles, traffic rules, etc. between vehicles, such as other vehicles intertwining, and traffic signals on city roads prevent vehicles traveling at one end of the link.
- an interrupt recovery request may be issued to the fleet manager or the cluster manager if the fleet manager is received within the predetermined time. Or the cluster manager's interrupt processing response, then the previous link can be restored, otherwise the link form or the fleet's network structure can be changed or the link can be abandoned.
- the specific strategy will depend on the current network structure and/or the broken chain. The extent to which the road affects the team. These policies can be notified to individual fleet members when initially allocating transmission resources for the link.
- the interrupt recovery request can be similarly sent to the member of the team as the transmitting end, if the interrupt processing response sent by the transmitting end is received within a predetermined time.
- the previous link can be restored, otherwise the link disruption is reported to the fleet manager or cluster manager, and further decisions are made by the fleet manager or cluster manager.
- Figure 9 is a diagram showing the flow of information for initiating link stability measurement and trigger event processing, in which the link sender team member A sends a message to the receiver team member B, and the team member B performs link stabilization while receiving.
- This event processing can be performed by the link receiver and/or by the fleet manager or cluster manager. It should be understood that although both the transmitting and receiving parties are shown as members of the fleet, the present invention is not limited thereto, and one of the transmitting and receiving parties may also be a fleet manager or a cluster manager.
- the electronic device 100 can measure link stability by adopting a link stability measurement configuration corresponding to the network structure of the fleet, and can quickly and accurately measure the stability of the link in the fleet. And the link stability measurement result can be utilized to perform processing of the corresponding event.
