Description

[0001] This application is a divisional application of the Chinese patent application "Service Information for V2X Service Coordination in Other Spectrums" with application number 201980089463.0 (filing date: January 18, 2019). Technical Field

[0002] The present invention relates to a method for controlling vehicle-to-everything (V2X) communication, and a corresponding radio device, system, and computer program. Background Art

[0003] V2X communication can be used to provide various services related to vehicles such as cars, trucks, buses, trains, ships, airplanes, motorcycles, and bicycles. V2X communication can include, for example: vehicle-to-vehicle (V2V) communication between vehicles; vehicle-to-pedestrian (V2P) communication between a vehicle and a device carried by an individual (such as a handheld terminal carried by a pedestrian, cyclist, driver, or passenger); vehicle-to-infrastructure (V2I) communication between a vehicle and a roadside unit (RSU) of the transportation infrastructure (such as an entity that sends a speed limit notice); and vehicle-to-network (V2N) communication between a vehicle and a node of a wireless communication network. Generally, V2X communication utilizes direct wireless transmission between V2X communication devices. However, in some cases, V2X communication can also utilize or be assisted by network infrastructure. V2X communication can be used to provide various V2X communication services, also known as V2X services.

[0004] Basic V2X services include intelligent transportation system (ITS) applications for improving road traffic safety and efficiency, such as those referred to by the European Commission as "day-one ITS services" in the deployment plan for Cooperative-ITS (C-ITS), see the Commission Decision on the coordinated use of the radio spectrum in the 5875 - 5905 MHz band for safety-related applications of intelligent transportation systems (ITS), notified in document number C(2008)4145 (2008 / 671 / EC) on August 5, 2008. Basic V2X services include hazardous location notifications, such as: slow or stationary vehicles and forward traffic warnings, road work warnings, weather conditions, emergency brake lights, emergency vehicle approach, other hazards. In addition, basic V2X services include signage applications, such as: in-vehicle signage, in-vehicle speed limit, signal violation and intersection safety, traffic signal priority requests for designated vehicles, green light optimal speed advice, detected vehicle data, shock wave damping.

[0005] For basic V2X services, dedicated ITS spectrums have been allocated in different regions of the world. In most regions, the dedicated ITS spectrum is in the range of 5.850 to 5.925 GHz, also known as the 5.9 GHz spectrum. In the dedicated 5.9 GHz ITS spectrum, only short-range V2X communication technologies are allowed. In addition, the allocated bandwidth in the dedicated 5.9 GHz ITS spectrum is very limited. For example, in Europe, only 30 MHz is used for safety-related basic V2X services.

[0006] In addition, various enhanced V2X (eV2X) services have been proposed. eV2X services include, for example, platooning, advanced driving, extended sensor data sharing, etc. The overall purpose of eV2X services is to enable autonomous driving and even connected autonomous vehicles. The collection of eV2X services can be found in 3GPP TR22.886 V15.3.0 (2018-09). J. Jia, K. Lu, and J. Wang described a platooning service in "On the network connectivity of platoon-based vehicular cyber-physical systems" in Transportation Research Part C: Emerging Technologies (40. 215-230, ISSN 0968-090X (2014)), where the platoon leader is responsible for inter-platoon communication.

[0007] Compared with basic V2X services, eV2X services may require significantly more bandwidth, which limits the possibility of providing eV2X services in the dedicated ITS band. In addition, providing eV2X services in the dedicated ITS band may, for example, have an adverse impact on basic ITS services by blocking resources. While V2X radio technologies can also use other frequency bands, such as the licensed bands for 5th Generation (5G) mobile communication networks or other International Mobile Telecommunications (IMT) services. However, in a given region, such licensed bands may be licensed to different Mobile Network Operators (MNOs). This may have the following impact: Devices associated with different MNOs will not be able to participate in direct eV2X communication in the licensed band.

[0008] Therefore, technologies are needed that allow for the efficient provision of different V2X services. SUMMARY OF THE INVENTION

[0035] In the following, concepts according to exemplary embodiments of the present invention will be explained in more detail with reference to the drawings. The illustrated embodiments relate to using service information transmitted in a first spectrum to control V2X communication in a coordinated manner, and in particular to effectively providing various V2X services such as basic V2X services and eV2X services, so that a V2X communication device can decide whether to use a first V2X service and / or a second V2X service.

[0036] In the example shown, one or more first V2X services are provided in a first spectrum, while one or more second V2X services are provided in a second spectrum different from the first spectrum. Further, in the first spectrum, the first V2X service may be based on a first radio technology, while in the second spectrum, the second V2X service may be based on a second radio technology. For example, the first V2X service may include basic V2X services aimed at improving traffic safety and efficiency. The second V2X service, in turn, may include eV2X services aimed at enabling autonomous driving functions (including self-driving). An example of an eV2X service is platooning, which involves coordinating the movement of vehicles in a group of vehicles so that the vehicles move in a well-defined formation. Another example of an eV2X service is the real-time sharing of vehicle sensor data by vehicles, including data provided by on-vehicle cameras, accelerometers, speedometers, or distance sensors. In the example shown, the first V2X service may be based on a short-range V2X radio technology, such as the LTE (Long-Term Evolution) PC5 interface specified by the 3rd Generation Partnership Project (3GPP). The second V2X service, in turn, may be based on another short-range V2X radio technology, such as the NR (New Radio) PC5 interface specified by the 3GPP. The first V2X service may be provided in a dedicated ITS band, such as the 5.9 GHz ITS band. The second V2X service may be provided in one or more other bands, such as one or more licensed bands. However, it should be noted that other combinations of radio technologies or spectrums may also be used. For example, in some scenarios, the first spectrum may also include licensed bands allocated to cellular networks, and in addition to or as an alternative to sending service information in the first V2X service, the service information may be sent by the cellular network. Further, the first radio technology or the second radio technology may also use, for example, a cellular downlink (DL) / uplink (UL) radio interface, such as the Uu interface specified by the 3GPP, such as the Universal Mobile Telecommunications System (UMTS) Uu interface, the LTE Uu interface, the 5G NR Uu interface, or use an ad-hoc radio technology, such as the ITS-G5 technology, the IEEE 802.11p / DSRC (Dedicated Short Range Communication) technology, or the IEEE 802.11bd / NGV (Next Generation V2X) technology.

[0037] Figure 1 An exemplary scenario involving V2X communication is shown. In particular, Figure 1 various entities 11, 12, 13, 14, 15 that can participate in V2X communication (as shown by the solid arrows) are shown. Further, Figure 1An access node 100 of a wireless communication network is shown, such as an eNB of LTE technology or a gNB of NR technology, or an access point of a wireless local area network (WLAN). At least some of the entities 11, 12, 13, 14, 15 are also capable of communicating by using DL radio transmission and / or UL radio transmission, as indicated by the dashed arrows. The service area or cell of the access node is schematically shown by 101. The service area 101 can be defined by a radio coverage area in which DL radio transmission from the access node 100 and UL radio transmission to the access node 100 are possible. Here, note that the wireless communication network may include other access nodes, each having a corresponding service area, which may or may not overlap with the coverage area 101 of the access node 100.

[0038] Figure 1 The entities shown include vehicles 11, 12, 13, mobile phones 14, and a person 15, such as a pedestrian, a cyclist, a vehicle driver, or a vehicle passenger. Here, it should be noted that in the case of vehicles 11, 12, 13, the radio transmission can be performed by a communication module installed in the vehicle, while in the case of the person 15, the radio transmission can be performed by a radio device (such as a wristband device or a similar wearable device) carried or worn by the person 15. These devices and modules can also be referred to as UEs. In addition, it should be noted that Figure 1 the entities shown are only exemplary, and other types of V2X communication devices can also be used in the shown concept. For example, V2X communication devices based on RSU or other infrastructure, V2X communication devices based in an aircraft (such as an airplane, a helicopter, a drone), in a spacecraft, in a train or a train car, in a ship, in a motorcycle, in a bicycle, in a mobility scooter, or in any other kind of mobile or transportation device.

[0039] Figure 2 The spectrum that can be used in the shown concept is schematically shown. Specifically, Figure 2An example of the above-described first spectrum (denoted as Spectrum 1) and second spectrum (denoted as Spectrum 2) is shown. In the example shown, the first spectrum includes a first frequency band (Band 1) and a second frequency band (Band 2). In the example shown, the first frequency band and the second frequency band are not adjacent. However, it should be noted that in other examples, the first frequency band and the second frequency band may also be adjacent. In addition, in the example shown, the second spectrum includes a third frequency band (Band 3), a fourth frequency band (Band 4), and a fifth frequency band (Band 5). In the example shown, the third frequency band, the fourth frequency band, and the fifth frequency band are not adjacent. However, it should be noted that in other examples, at least some of the third frequency band, the fourth frequency band, and the fifth frequency band may also be adjacent. Therefore, the first spectrum and the second spectrum may be continuous or discontinuous. In addition, it should be noted that the first spectrum and the second spectrum may be non-overlapping as Figure 2 shown, but an overlapping configuration is also possible. For example, one of the frequency bands of the first spectrum is arranged between two frequency bands of the second spectrum. In addition, it should be noted that Figure 2 the number of frequency bands shown is only exemplary, and both the first spectrum and the second spectrum may include fewer or more frequency bands. For example, the first spectrum may include only the first frequency band, while the second spectrum may include only the third frequency band.

[0040] In the following description, it is assumed that the first frequency band is a dedicated ITS frequency band allocated by regional or international regulations, such as the ITS frequency band between 5.855 GHz and 5.925 GHz specified in Europe or the ITS frequency band between 5.850 GHz and 5.925 GHz specified in the United States. The second frequency band, the third frequency band, the fourth frequency band, and the fifth frequency band may all be authorized frequency bands allocated to the same MNO or different MNOs, such as 5G frequency bands and / or IMT frequency bands. Here, a frequency band being authorized means that the use of the frequency band is generally only permitted for devices operated by the MNO to which the frequency band is allocated or for devices of users subscribed to the MNO to which the frequency band is allocated.

[0041] In the example described in further detail below, it is assumed that the first frequency band is used to provide basic V2X services. The third frequency band, the fourth frequency band, and / or the fifth frequency band are instead used to provide various eV2X services. Specifically, the third frequency band may be used to provide a first eV2X service, the fourth frequency band may be used to provide a second eV2X service, and the fifth frequency band may be used to provide a third eV2X service. However, two or more of the third frequency band, the fourth frequency band, and the fifth frequency band may also be used to provide the same eV2X service, and / or the same frequency band may be used to provide two or more of the first eV2X service, the second eV2X service, and the third eV2X service.

[0042] The first eV2X service, the second eV2X service, and the third eV2X service may differ in terms of the type of eV2X service, the radio technology used, the geographical area in which the eV2X service is available, or the requirements and conditions for using the eV2X service (such as radio technology requirements, communication protocol requirements, subscription requirements, billing requirements), etc. Further, the first eV2X service, the second eV2X service, and the third eV2X service may also differ in terms of the usage status (such as in terms of the number of active users or the occupancy level), and such usage status may change depending on time and / or depending on the geographical location.

[0043] According to the concepts shown, the first frequency band may be used to send service information. The service information indicates the availability of eV2X services in the second spectrum. This may also be referred to as advertising the eV2X services in the second spectrum. Specifically, the service information may indicate the availability of the first eV2X service in the third frequency band, the availability of the second eV2X service in the fourth frequency band, and / or the availability of the third eV2X service in the fifth frequency band. This may be done in one or more messages of the V2X service in the first frequency band. In some scenarios, a single message of the V2X service in the first frequency band may be used to indicate the availability of multiple eV2X services in the second spectrum, such as the availability of the first eV2X service in the third frequency band, such as the availability of at least two second eV2X services in the fourth frequency band, and the availability of the third eV2X service in the fifth frequency band. In other scenarios, separate messages of the V2X service in the first frequency band may be used for each of the multiple eV2X services in the second spectrum to indicate its availability.

[0044] In addition to or as an alternative to sending service information in the first frequency band, at least a part of the service information may also be sent in the second frequency band. In the second frequency band, the service information may be sent via a cellular radio technology (such as UMTS, LTE, or NR cellular radio technology). In this way, the availability of eV2X services in the second spectrum can be indicated in a wider area covered by the cellular radio technology.

[0045] Service information may indicate the type of eV2X service, such as platooning, vehicle sensor sharing, etc. Additionally or alternatively, the service information may indicate frequency information, such as one or more frequency bands, one or more frequency sub - bands within a frequency band, and / or one or more specific frequencies used to provide the eV2X service. Additionally or alternatively, the service information may indicate geographical information to indicate one or more geographical regions where the eV2X service is available. Additionally or alternatively, the service information may indicate the requirements and / or conditions for using the eV2X service, such as technical requirements like radio technology, communication protocols, etc., billing information, etc. Additionally or alternatively, the service information may indicate information about the current usage status of the eV2X service, such as the number of active users of the eV2X service, the occupancy level of the eV2X service, etc. The usage status may be indicated for a specific location (e.g., the location where the V2X communication device can receive the service information).

[0046] Figure 3A 、 3B Figures 3A, 3B, and 3C illustrate examples of how the concepts shown can be used to coordinate the use of V2X services in a first spectrum and the use of eV2X services in a second spectrum.

[0047] Figure 3A An initial scenario is shown in which multiple vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, i.e., multiple V2X communication devices, participate in V2X communication. In Figure 3A this scenario, vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 all use one or more V2X services in a first frequency band. As described above, one or more messages of the V2X services in the first frequency band can be used to send service information indicating the availability of eV2X services in a third frequency band, a fourth frequency band, and a fifth frequency band. At least a part of the service information can be provided via cellular radio communication in a second frequency band. Additionally, at least a part of the service information can be provided by one or more RSUs in one or more messages of the V2X services in the first frequency band. Additionally, one or more of vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can receive at least a part of the service information via cellular radio communication or from one or more RSUs and then forward the service information to other vehicles in one or more messages of the V2X services in the first frequency band.

[0048] Based on the received service information, vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can then decide whether to use one or more eV2X services in the second spectrum and whether to continue using the V2X services in the first spectrum. For each vehicle 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, this decision can be based on the technical capabilities of the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, e.g., the supported radio technologies or communication protocols supported by the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40. For example, if the technical capabilities of the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 match the technical requirements indicated by the service information for a particular eV2X service, the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can decide to use that eV2X service. Additionally, this decision can be based on the frequency band in which the eV2X service is provided. For example, if the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 support V2X communication in the frequency band indicated by the service information for a particular eV2X service, the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can decide to use that eV2X service. Additionally, this decision can be based on the geographical area where the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 are currently located or are expected to pass through. For example, if the geographical area matches the geographical area where the service information indicates the availability of a particular eV2X service, the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can decide to use that eV2X service. Additionally, this decision can be based on the usage status of a particular eV2X service indicated by the service information. For example, if the service information indicates that the number of users of a particular eV2X service is higher than a threshold, the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can decide to use that eV2X service. In this way, for example, the platooning service can only be used if a group of vehicles participating in the platooning service has a specific minimum size. According to another example, if the service information indicates that the occupancy level of a particular eV2X service is lower than a threshold, the vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can decide to use that eV2X service. In this way, it is possible to avoid, for example, participating in an eV2X service that is already close to its maximum occupancy. Additionally, the decision on whether to use a particular eV2X service can be based on whether the billing conditions indicated by the service information are acceptable. In this way, it is possible to avoid, for example, participating in an eV2X service that is too expensive. Additionally, the decision on whether to use a particular eV2X service can be based on various user preferences.Based on the same or similar criteria, vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 may also decide to stop using a specific eV2X service.

[0049] In Figure 3B 's example, it is assumed that vehicles 33, 34, and 35 decide to use the first eV2X service, such as the first platooning service for trucks. The corresponding V2X communication in the third frequency band is indicated by the dashed lines between vehicle 33 and vehicle 34 and between vehicle 34 and vehicle 35. Additionally, it is assumed that vehicles 36, 37, and 38 decide to use the second eV2X service, such as the second platooning service for trucks. The corresponding V2X communication in the fourth frequency band is indicated by the dashed lines between vehicle 36 and vehicle 37 and between vehicle 37 and vehicle 38. Additionally, it is assumed that vehicles 39 and 40 decide to use the third eV2X service, such as the platooning service for passenger cars. The corresponding V2X communication in the fifth frequency band is indicated by the dashed line between vehicle 39 and vehicle 40. Additionally, it is assumed that vehicles 31, 32 decide not to use any eV2X service indicated by the service information.

[0050] As Figure 3B shown by the solid lines in, vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can continue to use the V2X service in the first frequency band regardless of whether they use the eV2X service. Therefore, at least some of vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 can support multiple V2X technologies, such as LTE-V2X PC5 and NR V2X PC5, and support the simultaneous use of V2X communication in different frequency bands.

[0051] In many cases, the eV2X service can provide the same or even higher levels of safety-related functions as the basic V2X service. Given this situation, vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 may also decide whether to continue using the V2X service in the first frequency band while also using one of the eV2X services, thereby achieving more efficient use of radio resources in the first frequency band. To be able to discontinue using the V2X service in the first frequency band without negatively affecting safety-related functions, the concept shown can also involve selecting one or more representatives among a group of vehicles using a specific eV2X service to continue using the V2X service in the first frequency band while the other vehicles in the group stop using the V2X service in the first frequency band. Figure 3C The corresponding scenario is shown.

[0052] Figure 3C The scenario of Figure 3BStarting from the explained situation, among a group of vehicles 33, 34, 35 using the first eV2X service, vehicles 33 and 35 are selected as representatives. Among a group of vehicles using the second eV2X service, vehicles 36 and 38 are selected as representatives, and among a group of vehicles using the third eV2X service, vehicle 39 is selected as a representative. Accordingly, in Figure 3C In the scenario of, only vehicles 31, 32, 33, 34, 35, 36, 38, and 39 continue to use the V2X service in the first frequency band, while vehicles 34, 37, and 40 have stopped using the V2X service in the first frequency band. In this way, the efficiency of radio resource usage in the first frequency band can be improved, while still being able to implement safety-related V2X functions among vehicles 33, 34, 35, 36, 37, 38, 39, 40 using different eV2X services (for example, between vehicles 33, 34, 35 using the first eV2X service and vehicles 36, 37, 38 using the second eV2X service, and also between vehicles 33, 34, 35, 36, 37, 38, 39, 40 using one of the eV2X services in the eV2X service and vehicles 31, 32 using the V2X service in the first frequency band but not using the eV2X service).

[0053] The selection of vehicles 33, 34, 35, 36, 38, and 39 as representatives can be based on the relative positions of vehicles 33, 34, 35, 36, 38, and 39 within the group and / or their relationship with other vehicles 31, 32, 33, 34, 35, 36, 38, 39, 40 using another eV2X service or V2X service. This selection can be performed in a distributed manner, for example, based on the negotiation among vehicles 33, 34, 35, 36, 37, 38, 39, 40 in the group. In addition, it can also be performed in a centralized manner, for example, by a network node such as the above-mentioned access node 100 or by a specific vehicle 33, 34, 35, 36, 37, 38, 39, 40 within the group. For example, the selection can be performed by a vehicle 33, 34, 35, 36, 37, 38, 39, 40 designated as a platoon leader or a cluster leader. This selection can be performed in response to vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 joining the group, in response to vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 leaving the group, and / or in response to a change in conditions (such as a change in vehicle state (e.g., vehicle speed or vehicle acceleration), a change in road conditions (e.g., road curvature or road surface change), a change in environmental conditions (e.g., weather change), etc.).

[0054] Figure 4 An example of a process for controlling V2X communication based on the above principle is shown. Figure 4The process involves access node (AN) 100 and V2X communication devices 41, 42, 43 represented as "V2X-A", "V2X-B", and "V2X-C". The V2X communication devices 41, 42, 43 can correspond to any one of the above-mentioned entities 11, 12, 13, 14, 15 or to any one of the above-mentioned vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40. In addition, it should be noted that Figure 4 The number of V2X communication devices 41, 42, 43 in the example of

[0055] In Figure 4 the exemplary process, it is assumed that initially the V2X communication devices 41, 42, 43 initially use V2X services in a first frequency band, as indicated by the double arrows in block 401. As shown, this can involve all V2X communication devices 41, 42, 43 participating in direct V2X communication with each other.

[0056] As further shown, at a certain moment, the access node 100 sends service information 402. This can be done, for example, in a broadcast message of a cellular radio technology supported by the access node 100. The service information 402 can indicate the availability of at least one eV2X service in a second spectrum, such as the availability of the above-mentioned first eV2X service, second eV2X service, or third eV2X service. In addition to merely indicating the availability, the service information 402 can include additional information as described above.

[0057] In Figure 4 the example, the V2X communication device 41 receives the service information 402 and forwards at least a portion of the received service information 402, as indicated by service information 403. Similarly, the V2X communication device 42 receives the service information 402 and forwards at least a portion of the received service information 402, as indicated by service information 404, and at least a portion of the received service information 402 is received by the V2X communication device 43 in the example shown. In this way, the service information 402, 403, 404 can be propagated to different V2X communication devices 41, 42, 43, even if some of the V2X communication devices are not within the coverage of the access node 100 or not within the V2X communication coverage of one or more other V2X communication devices 41, 42, 43.

[0058] Based on the received service information 402, 403, 404, the V2X communication devices 41, 42, 43 then decide whether to use the eV2X services indicated by the service information 402, 403, 404 and whether to continue using the V2X services in the first frequency band. As indicated by blocks 405, 406, and 407, the V2X communication device 41 decides to join the eV2X service and leave the V2X service, the V2X communication device 42 decides to join the eV2X service and continue using the V2X service, and the V2X communication device 43 decides not to join the eV2X service and continue using the V2X service. This may for example involve selecting the V2X communication device 42 as a representative, as explained in conjunction with Figure 3C as explained.

[0059] As indicated by the double arrows in block 408, the V2X communication devices 41 and 42 can then use the eV2X service, while the V2X communication device continues to use the V2X service. The V2X communication device 42 can forward specific messages of the eV2X service, especially security-related messages, or information of specific messages from the eV2X service, especially security-related information, to the V2X communication device 43 in one or more messages of the V2X service. Similarly, the V2X communication device 42 can forward specific messages of the V2X service, especially security-related messages, or information of specific messages from the V2X service, especially security-related information, to the V2X communication device 41 in one or more messages of the eV2X service.

[0060] Figure 5 A flowchart is shown for illustrating a process by which a V2X communication device, such as any of the above entities 11, 12, 13, 14, 15 or vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, can operate in implementing the concepts shown. This exemplary process assumes that one or more basic V2X services are provided in a dedicated ITS frequency band corresponding to, for example, the first frequency band described above, and that one or more eV2X services are provided in one or more other frequency bands corresponding to, for example, one or more of the third, fourth, and fifth frequency bands described above.

[0061] In step 510, the V2X communication device uses the basic V2X service in the dedicated ITS frequency band. This may also involve the V2X communication device receiving, sending, or forwarding service information indicating the availability of one or more eV2X services, in Figure 5It is represented as eV2X service information in []. In step 520, the V2X communication device receives specific eV2X service information, which is used as the basis for deciding in step 530 whether the V2X communication device should join the eV2X service indicated by the eV2X service information. If the V2X communication device decides not to join the eV2X service, the process returns to step 510, as shown by the branch "No". If the V2X communication device decides not to join the eV2X service, the V2X communication device uses the eV2X service, as shown in step 540.

[0062] In step 550, the V2X communication device can check whether it is selected as a representative for forwarding messages or information between the basic V2X service and the eV2X service. If this is the case, the V2X communication device also uses the basic V2X service on behalf of one or more other users of the eV2X service, as shown by the branch "Yes" and step 560. If the V2X communication device is not selected as a representative, the V2X communication device can leave the eV2X service, as shown in step 570. After step 560 or 570, the process can continue with box 580, where the V2X communication device decides whether to leave the eV2X service, for example, based on updated service information received by the V2X communication device and / or based on detected condition changes. If the V2X communication device decides to leave the eV2X service, the process returns to step 510, as shown by the branch "Yes". If the V2X communication device decides not to leave the eV2X service, the process returns to step 540, as shown by the branch "No".

[0063] Figure 6 A flowchart showing a method for controlling V2X communication is shown, and this method can be used to implement the concepts shown. Figure 6 The method can be used to implement the concepts shown in a V2X communication device corresponding to, for example, any one of the above entities 11, 12, 13, 14, 15 or any one of the above vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40.

[0064] If a processor-based implementation of the V2X communication device is used, Figure 6 at least some steps of the method can be executed and / or controlled by one or more processors of the V2X communication device. Such a V2X communication device may also include a memory that stores program code for implementing Figure 6 at least some of the functions or steps of the method described below.

[0065] In step 610, the V2X communication device receives service information in a first spectrum. The service information indicates the availability of at least one V2X communication service in a second spectrum. The first spectrum may include a dedicated ITS band, for example, as for Figure 2as described for the first frequency band. Additionally, the first spectrum may include at least one authorized frequency band, such as as described for Figure 2 the second frequency band. The second spectrum may include at least one authorized frequency band, such as as described for Figure 2 the third, fourth, and fifth frequency bands.

[0066] The service information may indicate the type of at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate, for example, in terms of one or more frequency bands, one or more frequency sub-bands, and / or one or more individual frequencies, one or more frequencies used for at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate the geographical area in which at least one V2X communication service in the second spectrum is available. Additionally or alternatively, the service information may indicate the usage requirements for at least one V2X communication service in the second spectrum, such as requirements related to billing conditions, requirements related to the radio technology used for at least one V2X communication service in the second spectrum, or requirements related to the communication protocol used for at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate, for example, in terms of the number of users and / or in terms of the occupancy level, the usage status of at least one V2X communication service in the second spectrum.

[0067] At least one V2X communication service in the second spectrum may enable the coordination of the movement of a group of vehicles. For example, at least one V2X communication service in the second spectrum may correspond to a platooning service. Additionally or alternatively, at least one V2X communication service in the second spectrum may enable a group of vehicles to share sensor data, for example, for supporting autonomous driving functions.

[0068] A V2X communication device can receive service information based on a first radio technology, and at least one V2X communication service in a second spectrum can be based on a second radio technology different from the first radio technology. For example, the V2X communication device can receive at least a part of the service information based on the LTE PC5 V2X interface or based on an ad-hoc radio technology such as ITS-G5 technology, IEEE 802.11p / DSRC, or IEEE 802.11bd / NGV technology. In addition, the V2X communication device can receive at least a part of the service information based on a cellular radio technology. The V2X communication device can receive at least a part of the service information in the V2X communication service in the first spectrum, particularly in a dedicated ITS band. In addition, the V2X communication device can receive at least a part of the service information in the first spectrum (e.g., in the second band mentioned above) through a cellular network interface. In some scenarios, the V2X communication device can receive a first part of the service information in the first spectrum (e.g., in the second band mentioned above) through a cellular network interface and receive a second part of the service information in the first V2X communication service in the first spectrum, particularly in a dedicated ITS band.

[0069] In step 620, the V2X communication device can forward at least a part of the service information received in step 610, for example, as Figure 4 explained for the forwarded service information 403 and 404 in the example of. The V2X communication device can forward at least a part of the service information in the V2X communication service in the first spectrum, particularly in a dedicated ITS band.

[0070] In step 630, the V2X communication device controls the use of one or more V2X services by the V2X communication device. This is done based on the service information received in step 610. The control of the use at step 630 can involve, based on the received service information, the V2X communication device starting to use at least one V2X communication service in the second spectrum, for example, as illustrated for vehicles 33, 34, 35, 36, 37, 38, 39, and 40 in the scenario of Figure 3B or as illustrated for the V2X communication devices 41 and 42 in the example of Figure 4 . Additionally or alternatively, the control of the use at step 630 can involve the V2X communication device stopping to use at least one V2X communication service in the first spectrum, for example, as illustrated for vehicles 34, 37, and 40 in the scenario of Figure 3C or as illustrated for the V2X communication device 41 in the example of Figure 4 .

[0071] At step 640, the V2X communication device may participate in the selection of one or more other V2X communication devices for forwarding information between at least one V2X communication service in the second spectrum and at least one V2X communication service in the first spectrum, such as as illustrated for the selection of a representative in the scenario of Figure 3C or as illustrated for the forwarding of information or messages by the V2X communication device 42. The selection in step 640 may be based on the location of the V2X communication device using at least one V2X communication service in the second spectrum. In particular, the selection in step 640 may be based on the location of the V2X communication device using at least one V2X communication service in the second spectrum relative to the location of one or more V2X communication devices using at least one V2X communication service in the first spectrum.

[0072] In some scenarios, the selection in step 640 may be performed in response to the V2X communication device starting to use at least one V2X communication service in the second spectrum or in response to the V2X communication device stopping to use at least one V2X communication service in the second spectrum. Additionally or alternatively, the selection in step 640 may be performed in response to determining a change in the conditions for at least one V2X communication device to use at least one V2X communication service in the second spectrum.

[0073] The use of the V2X communication service by the V2X communication device (e.g., as controlled in step 630) may involve the V2X communication device transmitting one or more messages of one or more V2X communication services in the first spectrum or the second spectrum, as shown in step 650. Additionally, the use of the V2X communication service by the V2X communication device (e.g., as controlled in step 630) may involve the V2X communication device receiving one or more messages of one or more V2X communication services in the first spectrum or the second spectrum, as shown in step 660.

[0074] At step 670, the V2X communication device may forward one or more V2X messages and / or information from one or more V2X messages (e.g., the V2X messages received in step 660). Examples of such forwarding of information from one or more V2X messages or one or more V2X messages are illustrated in connection with the scenario of Figure 3C and in connection with the example of Figure 4 Accordingly, in some scenarios, the V2X communication device may receive one or more messages of at least one V2X communication service in the first spectrum and forward information from the received one or more messages in at least one V2X communication service in the second spectrum. Additionally, the V2X communication device may receive one or more messages of at least one V2X service in the second spectrum and forward information from the received one or more messages in at least one V2X communication service in the first spectrum.

[0075] Figure 7 shows a block diagram of the functions of a V2X communication device 700 for explaining the operation of a method according to Figure 6 . The V2X communication device 700 may correspond, for example, to any one of the above-mentioned entities 11, 12, 13, 14, 15 or any one of the above-mentioned vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40. As shown, the V2X communication device 700 may be provided with a module 710 configured to receive service information, such as that explained in connection with step 610. In addition, the V2X communication device 700 may optionally be provided with a module 720 configured to forward at least a portion of the received service information, such as that explained in connection with step 620. For example, the V2X communication device 700 may be provided with a module 730 configured to control the use of the V2X communication service by the V2X communication device 700, such as that explained in connection with step 630. In addition, the V2X communication device 700 may optionally be provided with a module 740 configured to participate in the selection of one or more forwarding V2X communication devices, such as that explained in connection with step 640. In addition, the V2X communication device 700 may optionally be provided with a module 750 configured to send one or more V2X communication messages, such as that explained in connection with step 650. In addition, the V2X communication device 700 may optionally be provided with a module 760 configured to receive one or more V2X communication messages, such as that explained in connection with step 660. In addition, the V2X communication device 700 may optionally be provided with a module 770 configured to forward one or more V2X communication messages, such as that explained in connection with step 670.

[0076] It should be noted that the V2X communication device 700 may include other modules for implementing other functions (such as known functions of the V2X communication device). In addition, it should be noted that the modules of the V2X communication device 700 do not necessarily represent the hardware structure of the V2X communication device 700, but may correspond to functional units implemented, for example, by hardware, software, or a combination thereof.

[0077] Figure 8 shows a flowchart of another method for controlling V2X communication, which can be used to implement the illustrated concept. Figure 8 The method of

[0078] can be used to implement the illustrated concept in a V2X communication device corresponding, for example, to any one of the above-mentioned entities 11, 12, 13, 14, 15 or any one of the above-mentioned vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40. Figure 8At least some steps of the method may be performed and / or controlled by one or more processors of the V2X communication device. Such a V2X communication device may also include a memory that stores program code for implementing at least some of the functions or steps described below for the Figure 8 method.

[0079] In step 810, the V2X communication device transmits service information in a first spectrum. The service information indicates the availability of at least one V2X communication service in a second spectrum. Here, it should be noted that the service information transmitted in the first band may also indirectly indicate the availability by referring to other service information transmitted in the first spectrum or another spectrum, for example, on a broadcast channel. For example, the service information transmitted by the V2X communication device may include a reference to other service information transmitted by one or more access nodes of the wireless communication network, for example, on a broadcast channel. Such an indirect reference may also be iterated multiple times.

[0080] The first spectrum may include a dedicated ITS band, for example, as illustrated for the Figure 2 first band. Additionally, the first spectrum may include at least one licensed band, for example, as illustrated for the Figure 2 second band. The second spectrum may include at least one licensed band, for example, as illustrated for the Figure 2 third, fourth, and fifth bands.

[0081] The service information may indicate the type of at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate, for example, in terms of one or more bands, one or more frequency sub-bands, and / or one or more individual frequencies, the one or more frequencies used for at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate the geographical area in which at least one V2X communication service in the second spectrum is available. Additionally or alternatively, the service information may indicate the usage requirements for at least one V2X communication service in the second spectrum, such as requirements related to billing conditions, requirements related to the radio technology used for at least one V2X communication service in the second spectrum, or requirements related to the communication protocol used for at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate the usage status of at least one V2X communication service in the second spectrum, for example, in terms of the number of users and / or in terms of the occupancy level.

[0082] At least one V2X communication service in the second spectrum may enable coordination of the movement of a group of vehicles. For example, at least one V2X communication service in the second spectrum may correspond to a platooning service. Additionally or alternatively, at least one V2X communication service in the second spectrum may enable sharing of sensor data among a group of vehicles, e.g., for supporting autonomous driving functions.

[0083] The V2X communication device may send service information based on a first radio technology, and at least one V2X communication service in the second spectrum may be based on a second radio technology different from the first radio technology. For example, the V2X communication device may send at least a part of the service information based on the LTE PC5 V2X interface or based on an ad-hoc radio technology such as ITS-G5 technology, IEEE 802.11p / DSRC, or IEEE 802.11bd / NGV technology. Additionally, the V2X communication device may send at least a part of the service information based on a cellular radio technology. The V2X communication device may send at least a part of the service information in the V2X communication service in the first spectrum, particularly in a dedicated ITS band. Additionally, the V2X communication device may send at least a part of the service information in the first spectrum (e.g., in the second band mentioned above) via a cellular network interface. In some scenarios, the V2X communication device may send a first part of the service information in the first spectrum (e.g., in the second band mentioned above) via a cellular network interface and send a second part of the service information in a first V2X communication service in the first spectrum, particularly in a dedicated ITS band.

[0084] The V2X communication device may determine the service information based on other information received by the V2X communication device, monitored by the V2X communication device, or otherwise available at the V2X communication device (e.g., through pre-configuration). Additionally, the V2X communication device may also determine the service information to be sent based on the received service information, i.e., forward at least a part of the service information received by the V2X communication device.

[0085] In step 820, the V2X communication device may participate in the selection of one or more V2X communication devices for forwarding information between at least one V2X communication service in the second spectrum and at least one V2X communication service in the first spectrum, e.g., as illustrated for the selection represented in the Figure 3C scenario or as illustrated for the forwarding of information or messages by the V2X communication device 42. The selection in step 820 may be based on the location of the V2X communication device using at least one V2X communication service in the second spectrum. In particular, the selection in step 820 may be based on the location of the V2X communication device using at least one V2X communication service in the second spectrum relative to the location of one or more V2X communication devices using at least one V2X communication service in the first spectrum.

[0086] In some scenarios, the selection in step 820 may be performed in response to the V2X communication device starting to use at least one V2X communication service in the second spectrum or in response to the V2X communication device stopping to use at least one V2X communication service in the second spectrum. Additionally or alternatively, the selection in step 820 may be performed in response to determining a change in the conditions for at least one V2X communication device to use at least one V2X communication service in the second spectrum.

[0087] As shown in step 830, the V2X communication device may also send one or more messages of one or more V2X communication services in the first spectrum or the second spectrum. Additionally, the V2X communication device may receive one or more messages of one or more V2X communication services in the first spectrum or the second spectrum, as shown in step 840. In step 850, the V2X communication device may forward one or more V2X messages and / or information from one or more V2X messages (such as the V2X messages received in step 830). Examples of the forwarding of information from one or more V2X messages or one or more V2X messages are described in connection with Figure 3C the scenarios and in connection with Figure 4 the examples. Thus, in some scenarios, the V2X communication device may receive one or more messages of at least one V2X communication service in the first spectrum and forward the information from the received one or more messages of at least one V2X communication service in the second spectrum. Additionally, the V2X communication device may receive one or more messages of at least one V2X service in the second spectrum and forward the information from the received one or more messages of at least one V2X communication service in the first spectrum.

[0088] Figure 9 illustrates for explaining according to Figure 8Block diagram of the functions of the V2X communication device 900 operated by the method. The V2X communication device 900 may correspond, for example, to any one of the above entities 11, 12, 13, 14, 15 or any one of the above vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40. As shown, the V2X communication device 900 may be provided with a module 910 configured to send service information, such as illustrated in connection with step 810. In addition, the V2X communication device 900 may optionally be provided with a module 920 configured to participate in the selection of one or more forwarding V2X communication devices, such as illustrated in connection with step 820. In addition, the V2X communication device 900 may optionally be provided with a module 930 configured to send one or more V2X communication messages, such as illustrated in connection with step 830. In addition, the V2X communication device 900 may optionally be provided with a module 960 configured to receive one or more V2X communication messages, such as illustrated in connection with step 840. In addition, the V2X communication device 900 may optionally be provided with a module 950 configured to forward one or more V2X communication messages, such as illustrated in connection with step 850.

[0089] It should be noted that the V2X communication device 900 may include other modules for implementing other functions (such as known functions of the V2X communication device). In addition, it should be noted that the modules of the V2X communication device 900 do not necessarily represent the hardware structure of the V2X communication device 900, but may correspond to functional units implemented, for example, by hardware, software, or a combination thereof.

[0090] Note that the Figure 6 and Figure 7 functions illustrated may also be combined with the Figure 8 and 9 functions illustrated in the same V2X communication device. For example, a V2X communication device that receives and uses service information according to the Figure 6 method may also determine and send service information according to the Figure 8 method, and optionally also use the service information in the same manner as described for the service information received according to the Figure 6 method.

[0091] Figure 10 A flowchart showing another method for controlling V2X communication is shown, which can be used to implement the illustrated concept. Figure 10 The method of

[0092] can be used to implement the illustrated concept in a network node corresponding, for example, to the above access node 100. Figure 10At least some steps of the method may be performed and / or controlled by one or more processors of a network node. Such a network node may also include a memory that stores program code for implementing at least some of the functions or steps described below for the Figure 10 method.

[0093] In step 1010, the network node transmits service information in a first spectrum. The service information indicates the availability of at least one V2X communication service in a second spectrum. Here, it should be noted that the service information transmitted in the first band may also indirectly indicate the availability by referring to other service information transmitted in the first spectrum or another spectrum, e.g., on a broadcast channel. For example, the service information transmitted by the network node may include a reference to other service information transmitted by one or more other network nodes (e.g., access nodes) of the wireless communication network, e.g., on a broadcast channel. Such an indirect reference may also be iterated multiple times.

[0094] The first spectrum may include a dedicated ITS band, e.g., as illustrated for the Figure 2 first band. Additionally, the first spectrum may include at least one licensed band, e.g., as illustrated for the Figure 2 second band. The second spectrum may include at least one licensed band, e.g., as illustrated for the Figure 2 third, fourth, and fifth bands.

[0095] The service information may indicate the type of at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate, e.g., in terms of one or more bands, one or more frequency sub-bands, and / or one or more individual frequencies, one or more frequencies used for at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate the geographical area in which at least one V2X communication service in the second spectrum is available. Additionally or alternatively, the service information may indicate the usage requirements for at least one V2X communication service in the second spectrum, e.g., requirements related to billing conditions, requirements related to the radio technology used for at least one V2X communication service in the second spectrum, or requirements related to the communication protocol used for at least one V2X communication service in the second spectrum. Additionally or alternatively, the service information may indicate the usage status of at least one V2X communication service in the second spectrum, e.g., in terms of the number of users and / or in terms of the occupancy level.

[0096] At least one V2X communication service in the second spectrum can enable the coordination of the movement of a group of vehicles. For example, at least one V2X communication service in the second spectrum can correspond to a platooning service. Additionally or alternatively, at least one V2X communication service in the second spectrum can enable a group of vehicles to share sensor data, for example, for supporting autonomous driving functions.

[0097] The network node can send service information based on a first radio technology, and at least one V2X communication service in the second spectrum can be based on a second radio technology different from the first radio technology. For example, the network node can send at least a part of the service information in the first spectrum, such as in the second frequency band mentioned above, through a cellular network interface based on a cellular radio technology.

[0098] The network node can determine the service information based on other information received by the network node, monitored by the network node, or otherwise (e.g., through pre-configuration) available at the network node. Additionally, the network node can also determine the service information to be sent based on the received service information, that is, forward at least a part of the service information received by the network node.

[0099] In step 1020, the network node can participate in the selection of one or more V2X communication devices for forwarding information between at least one V2X communication service in the second spectrum and at least one V2X communication service in the first spectrum, for example, as illustrated for the selection represented in the Figure 3C scenario or as illustrated for the forwarding of information or messages by the V2X communication device 42. The selection in step 1020 can be based on the location of the V2X communication device using at least one V2X communication service in the second spectrum. In particular, the selection in step 1020 can be based on the location of the V2X communication device using at least one V2X communication service in the second spectrum relative to the location of one or more V2X communication devices using at least one V2X communication service in the first spectrum.

[0100] In some scenarios, the selection in step 1020 can be performed in response to a V2X communication device starting to use at least one V2X communication service in the second spectrum or in response to a V2X communication device stopping to use at least one V2X communication service in the second spectrum. Additionally or alternatively, the selection in step 1020 can be performed in response to a determination of a change in the conditions for at least one V2X communication device to use at least one V2X communication service in the second spectrum.

[0101] Figure 11 Illustrated for explaining according to Figure 10Block diagram of the functionality of a network node 1100 operated by the method. The network node 1100 may correspond, for example, to the access node 100 described above. As shown, the network node 1100 may be provided with a module 1110 configured to send service information, such as described in connection with step 1010. Additionally, the network node 1100 may optionally be provided with a module 1120 configured to participate in the selection of one or more forwarding V2X communication devices, such as described in connection with step 1020.

[0102] Note that the network node 1100 may include other modules for implementing other functions (e.g., known functions of an access node or other types of network nodes). Additionally, it should be noted that the modules of the network node 1100 do not necessarily represent the hardware structure of the network node 1100, but may correspond to functional units implemented, for example, by hardware, software, or a combination thereof.

[0103] Note that in connection with Figure 6 and Figure 7 the functions described and / or in connection with Figure 8 and 9 the functions described may also be combined with the functions described in connection with Figure 10 and 11 in, for example, a system including a network node that sends service information according to the method of Figure 10 and one or more V2X communication devices that receive and use service information according to the method of Figure 6 . In addition to or as an alternative to the access node, such a system may also include one or more V2X communication devices that send service information according to the method of Figure 8 .

[0104] Figure 12 Shows a processor-based implementation of a V2X communication device 1200 that may be used to implement the above concepts. For example, Figure 12 the structure shown may be used to implement these concepts in any one of the above entities 11, 12, 13, 14, 15 or in any one of the above vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40.

[0105] As shown, the V2X communication device 1200 includes one or more radio interfaces 1210. The radio interfaces 1210 may support, for example, one or more of the above V2X communication technologies. Additionally, the radio interfaces 1210 may also support DL radio transmission and / or UL radio transmission based on cellular radio technologies (e.g., UMTS technology, LTE technology, and / or NR technology).

[0106] In addition, the V2X communication device 1200 may include one or more processors 1250 coupled to a radio interface 1210 and a memory 1260 coupled to the processor 1250. For example, the radio interface 1210, the processor 1250, and the memory 1260 may be coupled via one or more internal bus systems of the radio device. The memory 1260 may include read-only memory (ROM) (e.g., flash ROM), random access memory (RAM) (e.g., dynamic RAM (DRAM) or static RAM (SRAM)), mass storage (e.g., hard disk or solid state drive), and the like. As shown, the memory 1260 may include software 1270, firmware 1280, and / or control parameters 1290. The memory 1260 may include appropriately configured program code executed by the processor 1250 to implement, for example, the V2X communication device's functions in connection with Figures 6 to 9 the above-described functions illustrated.

[0107] It should be understood that Figure 12 the structure shown is merely illustrative, and the V2X communication device 1200 may actually include other components not shown for clarity, such as other interfaces or processors. Additionally, it should be understood that the memory 1260 may include other program code for implementing known functions of the V2X communication device, such as for implementing various types of V2X or eV2X services. According to some embodiments, a computer program for implementing the functions of the V2X communication device 1200 may also be provided, for example, in the form of a physical medium storing the program code and / or other data to be stored in the memory 1260 or by making the program code available for download or streaming.

[0108] Figure 13 A processor-based implementation of a network node 1300 that may be used to implement the above concepts is shown. For example, Figure 13 the structure shown may be used to implement these concepts in the above access node 100.

[0109] As shown in the figure, network node 1300 includes an access interface 1310. The access interface 1310 can be used to communicate with one or more radio devices via DL radio transmission and / or UL radio transmission and to control these radio devices. The radio devices can specifically include, for example, V2X communication devices corresponding to any one of the above entities 11, 12, 13, 14, 15 or any one of the above vehicles 31, 32, 33, 34, 35, 36, 37, 38, 39, 40. If the network node corresponds to an access node, the access interface 1310 can be a radio interface. However, in some scenarios, the network node 1300 can also correspond to a more centralized node, such as a core network node. In this case, the access interface 1310 can also correspond to an interface for communicating with an access node of a serving radio device. As further shown, the network node 1300 can also include a network interface 1320 that can be used to communicate with other network nodes.

[0110] In addition, the network node 1300 can include one or more processors 1350 coupled to the access interface 1310 and a memory 1360 coupled to the processor 1350. For example, the access interface 1310, the processor 1350, and the memory 1360 can be coupled via one or more internal bus systems of the network node 1300. The memory 1360 can include ROM (such as flash ROM), RAM (such as DRAM or SRAM), mass storage (such as a hard disk or a solid state drive), etc. As shown in the figure, the memory 1360 can include software 1370, firmware 1380, and / or control parameters 1390. The memory 1360 can include appropriately configured program code executed by the processor 1350 to implement, for example, the above functions of the network node in combination with Figure 10 and 11 as illustrated.

[0111] It should be understood that Figure 13 the structure shown is merely illustrative, and the network node 1300 can actually include other components not shown for the sake of clarity, such as other interfaces or processors. In addition, it should be understood that the memory 1360 can include other program code for implementing the known functions of an eNB for LTE technology, a gNB for NR technology, or other network nodes. According to some embodiments, a computer program for implementing the functions of the network node 1300 can also be provided, for example, in the form of a physical medium storing the program code and / or other data to be stored in the memory 1360 or by making the program code available for download or streaming.

[0112] As can be seen, the concepts described above can be used to effectively coordinate the provision of one or more V2X services. Specifically, by advertising one or more eV2X services in another spectrum, problems caused by insufficient bandwidth in the dedicated ITS band can be avoided. In addition, by electing representatives among the users of a specific basic V2X service from a group of eV2X service users and only allowing these representatives to send / receive messages of the same basic V2X service on behalf of the users of the same basic V2X service in the group of eV2X service users within the dedicated ITS band, these concepts can be used to further reduce the traffic load of the basic V2X service in the first spectrum, especially in the dedicated ITS band. Therefore, the safety-related functions of the basic V2X service can be maintained without all users in the group of eV2X service users continuing to use the basic V2X service. For users who are not representatives, the safety-related information in the message of the basic V2X service can be transmitted in the message of the eV2X service.

[0113] It should be understood that the examples and embodiments explained above are merely illustrative and are subject to various modifications. For example, the concepts shown can be applied in combination with various V2X radio technologies and combinations of radio technologies. In addition, these concepts can be applied with respect to various types of vehicles and eV2X service types. In addition, it should be understood that the above concepts can be implemented by using software of a corresponding design to be executed by one or more processors of existing devices or apparatuses or by using dedicated device hardware. In addition, it should be noted that the devices or apparatuses shown can be implemented as a single device or as a system of multiple interacting devices or modules.
