Description

Technical Field

[0001] This disclosure relates to the field of wireless communications. Embodiments relate to methods, apparatuses, vehicles, and computer programs for improving location information in user equipment, and more particularly, but not exclusively, to concepts for improving location information of one or more communication devices, such as improving a node map. Background Technology

[0002] The development of 5G has garnered increased attention from the automotive industry, a vertically integrated manufacturer anticipating the most advanced features of the next generation of wireless communication. Among 5G's key innovations, a wide spectrum of possibilities (currently licensed up to 28 GHz bands – the first millimeter-wave bands for mobile use), enhanced support for high-mobility scenarios, and new mechanisms for guaranteeing and predicting the quality of service (QoS) experienced have been established as key functionalities to support an increasingly connected transportation ecosystem. Furthermore, the latest standard release (Rel.16) has leveraged New Radio (NR) technology to support vehicle-to-everything (V2X) communication, reportedly allowing vehicles to utilize the same spectrum options, even for vehicle-to-vehicle (V2V) use cases.

[0003] NR support for V2X is provided, enabling vehicles to communicate at frequencies above 6 GHz. In 5G, these higher frequency bands are allocated across the mmWave spectrum (30-300 GHz). The use of higher frequency bands in communication implies more demanding channels (in which free-space path loss increases with frequency). The signal propagates during scaling and is significantly affected by obstructions and atmospheric effects (i.e., water vapor and oxygen absorption or rain). In some situations where signal power attenuation is increased, thus reducing the received signal-to-noise ratio, services relying on higher frequency systems with their inherently high channel-induced attenuation may find it difficult to deliver satisfactory QoS. Therefore, 5G user equipment (UE) relies on multi-antenna front-ends to perform beamforming and concentrate radiated power toward the intended transmitter / receiver. Thus, it is worth considering equipping vehicles with advanced multi-antenna systems.

[0004] Given the directional nature of a link, users (e.g., V2X nodes) aiming to communicate with their surrounding nodes in these frequency bands may not be able to easily identify all users. Directional beams can reach these nodes.

[0005] EP 3 471 075 A1 discloses a method for avoiding collisions between vulnerable road user vehicles and surrounding vehicles. The vulnerable road user vehicle can be a bicycle, motorcycle, scooter, road roller, etc. The method includes transmitting location detection sensor data or derived location data from the vulnerable road user vehicle to a portable communication device used by a user of the vulnerable road user. The portable communication device performs map matching technology to refine the location data and transmits the refined location data to the vulnerable road user vehicle. The vulnerable road user vehicle then performs the step of distributing the refined location data to surrounding vehicles, which calculate the trajectory of the vulnerable road user vehicle and estimate the risk of collision.

[0006] US 10 098 014 B1 discloses a beam alignment method based on driving intent. One approach includes: The method receives a wireless message including first vehicle data describing the position, speed, heading, and driving intention of a first vehicle. The method further includes determining whether a blockage is predicted based on the position of a second vehicle, the driving intention of the second vehicle, and the first vehicle data. The method further includes determining a non-line-of-sight (NLOS) path based on the second vehicle position, the second vehicle driving intention, and the first vehicle data in response to a predicted blockage. The method further includes performing beam alignment between the first and second vehicles based on the NLOS path prior to the predicted blockage.

[0007] EP 3 687 082 A1 discloses embodiments for modifying a vehicle-to-everything (V2X) radio of a first endpoint based on beam alignment feedback data. In some embodiments, a method for a first endpoint includes detecting an intention of the first endpoint to exchange first millimeter-wave (mmWave) messages with a second endpoint. The method includes determining situation data describing a situation of one or more of the first and second endpoints. The method includes requesting a recommended beam alignment setting from a connectivity computing device based on the situation data. The method includes receiving feedback data from the connectivity computing device describing the recommended beam alignment setting. The method includes modifying the operation of the V2X radio of the first endpoint based on the recommended beam alignment setting, such that the V2X radio of the first endpoint exchanges mmWave messages with the second endpoint using the recommended beam alignment setting.

[0008] V2X nodes can continuously monitor their surroundings to search for hazards or anomalies. It is foreseeable that V2X nodes will proactively attempt to use the received V2X data to prevent their own dangerous situations, and to share information (sensor data, identified hazards, etc.) with other nearby V2X nodes so that they can perform the same actions, thereby gaining a collective understanding of the environment and making roads safer.

[0009] However, it's possible that communication in high-frequency bands (such as mmWave) will be based on unicast / multicast, where data will be addressed to specific V2X nodes, and beamforming will be performed between nodes to maximize performance. Given the inherent directionality of these links, the transmitting V2X node may not have a complete picture of the nodes to which the message is addressed. This is important, for example, if a hazard is detected in an area and safety-critical data needs to be transmitted to vulnerable vehicles in adjacent areas. Therefore, improvements to V2X node discovery may be necessary, especially in high-frequency bands.

[0010] Therefore, the improved determination of location information allows user devices to generate node maps with improved location information. This can then reduce inefficient periodic updates. For example, a V2X node might have a complete picture of the node to which a message is addressed. This can improve communication between different user devices (e.g., two different V2X nodes (e.g., two different vehicles)) because, for example, beamforming in communication between the two user devices can be improved. Summary of the Invention

[0011] An example provides a method for improving location information of one or more communication devices. The method includes obtaining map information about the location of the one or more communication devices, and determining radio channel information about the one or more communication devices by analyzing radio channels. Additionally, the method includes generating a node map that includes improved location information of the one or more communication devices using the map information and the radio channel information. Thus, the node map can be used, for example, to adjust transmission parameters (e.g., beamwidth, departure angle, angle of arrival, etc.), which can improve communication between the user equipment and the one or more communication devices.

[0012] In one example, the radio channel information could be spatial radio channel information belonging to the antenna system of the user equipment. Thus, the user equipment can easily determine the radio channel information using its antenna system. For example, the radio channel information can be determined during normal operation of the user equipment's antenna system.

[0013] In one example, the method may further include transmitting the generated node map to another user equipment. This allows the other user equipment to use the node map without having to generate it. Thus, the other equipment can, for example, adjust transmission parameters (e.g., beamwidth, departure angle, arrival angle, etc.), which can increase communication between the other user equipment and the one or more communication devices.

[0014] In one example, the method may further include transmitting radio channel information to another user equipment. The other user equipment can then use the radio channel information provided by the user equipment to generate an additional node map. This reduces data traffic between the user equipment and other user equipment while still enabling increased communication between the other user equipment and the one or more communication devices.

[0015] In one example, the generated node map and / or the radio channel information can be transmitted via broadcast messages. Thus, the node map and / or radio channel information can be received by multiple communication devices, for example, by V2X nodes not connected to the user equipment.

[0016] In one example, the method may further include periodically determining radio channel information and periodically determining a node map based on the periodically determined radio channel information. This allows the node map to be updated periodically, which can increase communication between other user equipment and the one or more communication devices because it can be adjusted in a timely manner.

[0017] In one example, the method may further include receiving additional radio channel information from another user equipment, and using the additional radio channel information to edit a node map including the one or more communication devices. Thus, the user equipment can use the additional radio channel information to improve the node map.

[0018] The example relates to a method for improving location information of one or more communication devices for use by an additional user equipment. The method includes obtaining map information about the location of the one or more communication devices and receiving radio channel information about the one or more communication devices from the user equipment. Additionally, the method includes generating a node map that includes the improved location information of the one or more communication devices using the map information and the radio channel information. Thus, the additional user equipment can use the radio channel information provided by the user equipment to generate an additional node map. This improves communication between the additional user equipment and the one or more communication devices without requiring the additional user equipment to determine the radio channel information.

[0019] In one example, another radio channel information is received from another user equipment, and the node map including the one or more communication devices is edited using the other radio channel information. Thus, another user equipment can use the other radio channel information to improve the node map.

[0020] In one example, the method may further include transmitting a request for the radio channel information and / or another radio channel information. Thus, additional user equipment can request the radio channel information and / or another radio channel information to generate a node map.

[0021] In one example, the method may further include transmitting the generated node map to a user device and / or another user device. This allows the user device and / or another user device to use the node map without having to generate it.

[0022] In one example, the generated node map, the radio channel information, and / or the other radio channel information are transmitted via broadcast messages. Thus, the node map, radio channel information, and / or the other radio map information can be received by multiple communication devices (e.g., by V2X nodes not connected to other user equipment).

[0023] The example further provides an apparatus including one or more interfaces configured to communicate with a communication device or a user equipment. The apparatus further includes a processing circuitry configured to control the one or more interfaces and perform the methods described above for user equipment and / or communication devices.

[0024] The example further provides vehicles that include the equipment described above.

[0025] The example further relates to a computer program having program code that, when executed on a computer, processor, or programmable hardware component, performs the methods described above. Attached Figure Description

[0026] The following are some examples of devices and / or methods described only by way of example and with reference to the accompanying drawings, in which: Figure 1 An example of a method for a user device is shown; Figure 2 Examples of methods for use with other user devices are shown; and Figure 3 A block diagram of the device is shown. Detailed Implementation

[0027] Some examples will now be described in more detail with reference to the accompanying drawings. However, other possible examples are not limited to the features of these embodiments described in detail. Other examples may include modifications to features, as well as equivalents and alternatives to features. Furthermore, the terminology used herein to describe certain examples should not limit other possible examples.

[0028] Throughout the description of the accompanying drawings, the same or similar reference numerals refer to the same or similar elements and / or features, which may be implemented in equivalent or modified forms while providing the same or similar functions. For clarity, the thickness of lines, layers, and / or areas in the drawings may also be enlarged.

[0029] When 'or' is used to combine two elements A and B, it is to be understood as disclosing all possible combinations, i.e., only A, only B, and A and B, unless otherwise explicitly defined in individual cases. As alternative wording for the same combination, 'at least one of A and B' or 'A and / or B' can be used. This is equivalent to combinations of more than two elements.

[0030] If the singular form such as “a,” “an,” and “the” is used, and the use of a single element is not explicitly or implicitly defined as mandatory, then other examples may use several elements to achieve the same functionality. If the functionality is described below as being implemented using multiple elements, then other examples may use a single element or a single processing entity to achieve the same functionality. It should be further understood that the terms “comprising” and / or “including”, when used, describe the presence of the specified features, integers, steps, operations, processes, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, processes, elements, components, and / or groups thereof.

[0031] Figure 1 An example of a method 100 for a user equipment is shown. Method 100 for a user equipment is used to improve location information of one or more communication devices. Method 100 includes obtaining 110 map information about the location of the one or more communication devices, and determining 120 radio channel information about the one or more communication devices by analyzing radio channels. Additionally, method 100 includes generating 130 a node map including improved location information of the one or more communication devices using the map information and the radio channel information. Thus, the UE can use the node map to communicate with the one or more communication devices, which can improve communication reliability because the location information of the one or more communication devices is improved.

[0032] A UE can communicate with one or more communication devices (e.g., base stations) in a mobile communication system. For example, a UE and one or more communication devices can communicate within / via a mobile communication system. A mobile communication system may include multiple transmission points and / or base stations operable to communicate radio signals with the UE. In one example, a mobile communication system may include a UE and one or more communication devices.

[0033] Communication devices (e.g., one or more communication devices) can be located in fixed or static parts of a network or system. Communication devices can correspond to remote wireless heads, transmission points, access points, macro cells, small cells, microcells, picocells, femtocells, metropolitan area cells, etc. The term small cell can refer to any cell smaller than a macro cell, i.e., a microcell, picocell, femtocell, or metropolitan area cell. Furthermore, a femtocell is considered smaller than a picocell, and a picocell is considered smaller than a microcell. Communication devices can be wireless interfaces of wired networks that enable the transmission and reception of radio signals to and from a UE (such as a UE or UE-compliant device). These radio signals can conform to, for example, radio signals standardized by 3GPP, or generally conform to one or more of the systems listed above. Thus, communication devices can correspond to NodeBs, eNodeBs, BTSs, access points, etc.

[0034] Mobile communication systems can be cellular. The term "cell" refers to the coverage area of ​​radio services provided by a transmission point, remote unit, remote head, remote radio head, communication device, UE, or NodeB, eNodeB. The terms "cell" and "base station" can be used synonymously. A wireless communication device (e.g., UE) can register with or associate with at least one cell (e.g., a communication device), that is, it can be associated with a cell to enable the exchange of data between mobile devices connected to or linked in the network and within the coverage area of ​​the associated cell using dedicated channels, connections, or links.

[0035] Typically, a UE is a device capable of wireless communication. However, specifically, a UE can be a mobile UE, i.e., a UE suitable for being carried by a user. For example, within the meaning of the corresponding communication standard used for mobile communication, a UE can be a user terminal (UT) or user equipment (UE). For example, a UE can be a mobile phone, such as a smartphone, or another type of mobile communication device, such as a smartwatch, laptop computer, tablet computer, or autonomous augmented reality glasses. For example, a UE and one or more communication devices can be configured to communicate in a cellular mobile communication system. Thus, the UE and communication devices can be configured to communicate in a cellular mobile communication system, such as a Sub-6GHz-based cellular mobile communication system (covering the frequency band between 500 MHz and 6 GHz) or an mmWave-based cellular mobile communication system (covering the frequency band between 20 GHz and 60 GHz). Typically, a mobile communication system can correspond, for example, to one of the mobile communication networks standardized by the 3rd Generation Partnership Project (3GPP), where the term mobile communication system is used synonymously with mobile communication network. Mobile communication systems can correspond to, for example, fifth-generation systems (5G), Long Term Evolution (LTE), LTE-A Advanced (LTE-A), High-Speed ​​Packet Access (HSPA), Universal Mobile Telecommunications System (UMTS) or UMTS Terrestrial Radio Access Network (UTRAN), Evolved UTRAN (e-UTRAN), Global System for Mobile Communications (GSM) or Enhanced Data Rate GSM Evolution (EDGE) networks, GSM / EDGE Radio Access Network (GERAN), or mobile communication networks with different standards, such as the Global Microwave Access Interoperability (WIMAX) network IEEE 802.16, typically orthogonal frequency division multiple access (OFDMA) networks, time division multiple access (TDMA) networks, code division multiple access (CDMA) networks, wideband CDMA (WCDMA) networks, frequency division multiple access (FDMA) networks, space division multiple access (SDMA) networks, etc.

[0036] Furthermore, the UE / one or more communication devices may be adapted to communicate via non-cellular communication systems or configured to communicate via non-cellular communication systems, such as via device-to-device vehicle communication systems (e.g., according to the IEEE 802.11p standard (IEEE 802.11p standard for vehicle communication)) or via wireless local area networks (e.g., according to IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11ac, or IEEE 802.11ax, also known as Wi-Fi 1 to Wi-Fi 6(E)). Specifically, the UE and one or more communication devices may be adapted to communicate in the frequency band between 5 GHz and 7.1 GHz or configured to communicate in the frequency band between 5 GHz and 7.1 GHz, which covers communication in the 5 GHz band (for WiFi in the 5 GHz band), the 5.9 GHz band (for vehicle communication according to the 802.11p standard), and between 5.9 GHz and 7.1 GHz (for WiFi in the 6 GHz band).

[0037] The connection between the UE and one or more communication devices can be a wireless connection, such as an mmWave-based connection via a mobile communication system (e.g., using a carrier frequency of at least 20 GHz), or it can be performed at a lower carrier frequency, such as using a carrier frequency of up to 7.5 GHz. For example, the wireless connection between the UE and one or more communication devices can be initiated using protocols of a mobile communication system or using a short-range communication system, such as via a wireless local area network outlined above.

[0038] As can be clearly seen from the examples above, although communication between the UE and one or more communication devices occurs via a mobile communication system, additional and / or alternative communications between the UE and one or more communication devices (e.g., one or more communication devices may be vehicles) can occur via a vehicle communication system. This communication can be implemented directly, for example, via device-to-device (D2D) communication. This communication can be implemented using the specifications of a vehicle communication system. Examples of D2D are direct communication between vehicles, also known as vehicle-to-vehicle (V2V) or vehicle-to-everything (V2X), car-to-car, and dedicated short-range communication (DSRC). Technologies for implementing this D2D communication include 802.11p, 3GPP systems (4G, 5G, NR and higher), etc.

[0039] Obtaining 110 map information can be done at least partially in advance, for example, by downloading / loading a map. Thus, the map can indicate the location of one or more communication devices. The map may include location information about the one or more communication devices, independent of the UE's location, and / or the map may include information about line-of-sight conditions between the UE and the one or more communication devices (e.g., a line-of-sight map).

[0040] For example, the UE can download maps and combine location information of one or more communication devices with radio channel information. Optionally or alternatively, the UE can obtain map information in real time, for example, through measurement, or receive real-time measurement data. For example, the UE (e.g., a vehicle) can use a wide variety of onboard sensor data types, including radar sensor data and lidar sensor data, but can also use, for example, vision-related sensors (such as cameras and IR sensors) and ultrasonic sensors to determine the location of communication devices. Optionally or alternatively, the UE can receive (real-time) map information from another UE or a base station in the UE environment. For example, the UE can receive map information through, for example, cooperative awareness messages, distributed environment notification messages, collective cognitive messages, etc.

[0041] Radio channel information can correspond to radio channel transmission parameters, radio channel usage depending on the UE's location, radio channel availability depending on the UE's location, wireless access technology, mobile system communication provider, etc. Determining radio channel information can be performed, for example, by determining the UE's antenna system settings and / or by determining whether communication using the radio channel is possible. For example, the UE may not sense any communication devices in its (line-of-sight) area of ​​environment. Thus, the UE can determine that there may be no communication devices in that area, and if, in the map information, one or more (misleading) communication devices are located in that area, the UE can generate a node map by removing the (misleading) communication device from the map information for that area.

[0042] Optionally or alternatively, the UE can use antenna system settings to sense a communication device at a first location, and map information can indicate that there is no communication device at the first location, but there is a (misplaced) communication device nearby. Thus, the UE can generate a node map by assigning the first location to this (misplaced) communication device.

[0043] Generating a 130-node map can be performed by the UE's processing circuitry. To generate the 130-node map, a weighted average of map information and radio channel information can be used. For example, radio channel information (e.g., location information determined using radio channel information) can be prioritized over map information. Thus, if the map information and radio channel information provide conflicting location information for one or more communication devices, the node map can include only the location information of the one or more communication devices that match the radio channel information.

[0044] Alternatively, radio channel information can be used to indicate the reliability of the location of one or more communication devices extracted from map information. For example, if the radio channel information matches the map information of a communication device, the location of that communication device can be indicated as reliable, while if the map information contradicts the radio channel information, the location of that communication device can be indicated as unreliable. This improves the use of node maps because reliable nodes can be identified. Alternatively, map information can be used to indicate the reliability of the location of one or more communication devices extracted from radio channel information (as in the context of the opposite example above).

[0045] Improved location information can be, for example, the corrected location of one or more communication devices and / or location information extracted from map information, which is improved by an indication of the reliability of the location information provided by radio channel information (and vice versa).

[0046] In one example, radio channel information could be spatial radio channel information belonging to the antenna system of a user equipment. Therefore, radio channel information could include location information of one or more communication devices, which could be used to improve the location information of one or more communication devices.

[0047] For example, the UE's antenna system can be configured to receive signals at a fixed angle of arrival. Knowing the angle of arrival, the UE can determine location information based on the received radio signals. Optionally or alternatively, the UE can determine location information based on signal strength. For example, by combining information about the spatial direction and signal strength of the radio signals, the UE can determine the exact location of a transmitter (e.g., one or more communication devices). Thus, improved location information for one or more communication devices can be determined by combining location information extracted from map information and location information extracted from radio channel information. This allows for the enhancement of location information for one or more communication devices.

[0048] In one example, the method may further include transmitting the generated node map to another user equipment. Thus, the other UE can use the node map to determine the location of one or more communication devices in an improved manner.

[0049] In one example, the method may further include transmitting radio channel information to another user equipment (UE). This allows the other UE to determine the node map in an improved manner. For example, due to different locations (and inferred different line-of-sight conditions), the UE may sense one or more different communication devices as another UE. By transmitting the radio channel information, the other UE can use this additional radio channel information to generate or edit the node map, which can improve the reliability of the node map.

[0050] In one example, the generated node map and / or the radio channel information can be transmitted via broadcast messages. Thus, the node map and / or radio channel information can be easily shared with other communication devices in the communication system, such as with another UE.

[0051] In one example, the method may further include periodically determining radio channel information and periodically determining a node map based on the periodically determined radio channel information. This allows the node map to be updated periodically. For example, one or more communication devices may be mobile; for instance, a communication device may be a vehicle acting as a relay system to establish a connection between the UE and a base station. For example, the vehicle may provide relay services based on a line-of-sight map. Thus, the UE can use the vehicle as a relay system and can use the periodically determined radio channel information to determine whether the vehicle is still in the same location. For example, if the UE can sense the movement of the vehicle, the UE can edit the node map based on the movement of the vehicle. Therefore, the UE can generate / edit the node map in a way that the node map is dynamic and includes information about the predicted locations of one or more communication devices.

[0052] In one example, the method may further include receiving additional radio channel information from another user equipment and using the additional radio channel information to edit a node map that includes one or more communication devices. Thus, the UE can edit the node map based on, for example, line-of-sight information from another device, because the other UE can sense one or more different communication devices as the UE.

[0053] To perform method 100, the vehicle may include a user equipment (UE). The UE may be equipped with a connectivity system (CS) to handle V2X communications. The CS is equipped with an antenna system (AS) with one or more panels, each panel facing a different radiation direction, and consisting of one or more antenna elements fed by a digitally controlled analog feed network.

[0054] For example, a vehicle can obtain map information by receiving node maps from other V2X nodes, such as one or more communication devices, regular V2X messaging (e.g., cooperative sensing messages, distributed environment notification messages, collective cognition messages), and the use of sensor data (e.g., radar, lidar, cameras).

[0055] For example, radio channel information can be determined by the angle of arrival of received messages associated with a node and / or the location of the antenna array. Additionally, vehicles can incorporate information such as intent data, including received or predicted trajectories, to account for the future location of one or more communication devices.

[0056] The UE can combine map information and radio channel information through data fusion to improve the location information of one or more communication devices. The improved location information can be used to generate a node map, which can be stored locally by the UE. This node map can be updated by triggering events, such as receiving new map information, determining new radio channel information, etc., and / or updated periodically, for example, using a fixed time period independent of the node map or the radio channel information.

[0057] Additionally, the UE can broadcast the generated node map periodically or aperiodically. This allows other UEs to use the generated node map. Furthermore, other UEs can generate additional node maps based on the node map and additional radio channel information (e.g., determined by the other UE).

[0058] For example, node maps can be broadcast via the sub-6GHz V2X band to extend data propagation.

[0059] For example, V2X communication between a UE and one or more communication devices can utilize wireless local area network (WLAN) technology and operate directly between vehicles and vehicles (V2V) and / or transportation infrastructure (V2I). When two V2X senders enter each other's range, they form a vehicle self-organizing network. Messages such as Cooperative Awareness Messages (CAM) or Basic Safety Messages (BSM) and Distributed Environment Notification Messages (DENM) can be used for communication between vehicles. Other roadside infrastructure-related messages include Signal Phase and Timing Messages (SPAT), In-Vehicle Information Messages (IVI), and Service Request Messages (SRM).

[0060] In situations where the goal is to establish a link with one or more (discovered) communication devices, the UE can make an initial guess about the antenna system configuration to define beaming strategies (such as reduced beamset for beam scanning, beamwidth, departure angle, antenna weights, etc.) to transmit signals. This initial guess may be based on relative positions, predicted / expected trajectories of both transmitting and receiving nodes, angle of arrival, etc.

[0061] Communication that occurs prior to connection establishment and can be used to obtain the information may be based on broadcasting by the UE, for example, via a mobile communication system. Therefore, the UE may be adapted or configured to communicate in or via one or more communication devices. For example, the UE, and in particular one or more communication devices, may be configured to communicate via one or more antennas through a mobile communication system. Additionally, the UE and one or more communication devices may be configured to communicate via short-range communication, for example, via a wireless local area network according to a variant of the IEEE 802.11 standard, via Bluetooth, or via UWB.

[0062] Further details and aspects are mentioned in conjunction with the embodiments described above and / or below. Figure 1 The examples shown may include those in conjunction with the proposed concepts or one or more of the following examples (e.g., Figure 2-3 One or more additional features corresponding to one or more aspects mentioned.

[0063] Figure 2 Another example of a method 200 for an additional user equipment is shown. Method 200 for a user equipment is used to improve location information of one or more communication devices. The method includes obtaining 210 map information about the location of one or more communication devices, and receiving 220 radio channel information about the one or more communication devices from the user equipment. Additionally, method 200 includes generating 230 a node map including improved location information of one or more communication devices using the map information and the radio channel information. This enables the additional UE to generate a node map including the improved location information without determining the radio channel information. As mentioned above, the radio channel information may include information about one or more communication devices that the additional UE cannot sense. Therefore, the determination of the node map can be improved.

[0064] In one example, method 200 may further include receiving additional radio channel information from another user equipment and using the additional radio channel information to edit a node map including one or more communication devices. Thus, the node map can be improved based on the additional radio channel information, which may include information about the one or more communication devices not included in the original radio channel information. Furthermore, the error in determining location information based on radio channel information can be reduced by using additional location information, as redundancy may occur, and the reliability of the determined location information can be improved.

[0065] In one example, method 200 may further include transmitting a request for the radio channel information and / or another radio channel information. Thus, for example, after a connection to a node determined by map information has failed, the additional UE may request information required for improved location information. In this way, the additional UE can adaptively generate a node map if problems arise.

[0066] In one example, method 200 may further include transmitting the generated node map to a user device and / or another user device. Thus, the user device and / or another user device can also use the generated node map.

[0067] In one example, the generated node map, the radio channel information, and / or the other radio channel information are transmitted via broadcast messages. Thus, the node map, radio channel information, and / or the other radio map information can be received by multiple communication devices (e.g., by V2X nodes not connected to other user equipment).

[0068] Further details and aspects are mentioned in conjunction with the embodiments described above and / or below. Figure 2 The examples shown may include those in conjunction with the proposed concepts or those above ( Figure 1 ) and / or below (e.g. Figure 3 One or more optional additional features corresponding to one or more aspects mentioned in one or more examples described.

[0069] Figure 3 A block diagram of device 30 is shown. Device 30 includes one or more interfaces 32 configured to communicate with a communication device or user equipment. Device 30 further includes a processing circuitry 34 configured to control the one or more interfaces and perform the above (e.g., see reference). Figure 1-2The method described is for use with a communication device. Device 30 may include a means of transportation. For example, the means of transportation may be a land vehicle, such as a road vehicle, automobile, car, off-road vehicle, motor vehicle, bus, robotaxi, van, truck, or truck-trailer. Alternatively, the means of transportation may be any other type of vehicle, such as a train, subway train, ship, or vessel. For example, the proposed concept can be applied to public transportation (trains, buses) and future mobile components (e.g., robotaxi).

[0070] For example, device 30 may be a communication device, wherein the interface is configured to communicate with another communication device. Alternatively, device 30 may be another communication device, wherein interface 32 is configured to communicate with a communication device.

[0071] like Figure 3 As shown, one or more corresponding interfaces 32 are coupled to a corresponding processing circuitry 34 at device 30. In the example, the processing circuitry 34 may be implemented using one or more processing units, one or more processing devices, or any component for processing, such as a processor, computer, or programmable hardware component operable with appropriately adapted software. Similarly, the functionality of the described processing circuitry 34 may also be implemented in software, which then executes on one or more programmable hardware components. Such hardware components may include general-purpose processors, digital signal processors (DSPs), microcontrollers, etc. The processing circuitry 34 is capable of controlling the interfaces 32 such that any data transfers occurring on the interfaces and / or any interactions where the interfaces can be invoked can be controlled by the processing circuitry 34.

[0072] In one embodiment, device 30 may include a memory and at least one processing circuitry system 34, the processing circuitry system being operatively coupled to the memory and configured to perform the methods described below.

[0073] In the example, one or more interfaces 32 can correspond to any component used to acquire, receive, transmit, or provide analog or digital signals or information, such as any connector, contact, pin, register, input port, output port, conductor, channel, etc., which allows the provision or acquisition of signals or information. The interface can be wireless or wired, and it can be configured to communicate with other internal or external components, i.e., to transmit or receive signals or information. One or more interfaces 32 can include other components to enable communication between vehicles. Such components can include transceiver (transmitter and / or receiver) components, such as one or more low-noise amplifiers (LNAs), one or more power amplifiers (PAs), one or more duplexers, one or more dual-signalers, one or more filters or filter circuit systems, one or more converters, one or more mixers, correspondingly adapted RF components, etc.

[0074] Further details and aspects are mentioned in conjunction with the above embodiments. Figure 3 The examples shown may include those in conjunction with the proposed concepts or those above ( Figure 1-2 One or more optional additional features corresponding to one or more aspects mentioned in one or more examples described.

[0075] The aspects and features described in a particular example from the previous examples can also be combined with one or more other examples to replace the same or similar features of that other example, or additionally introduce those features into that other example.

[0076] Examples may conform to or even be included in certain standard specifications, such as those defined by 3GPP. For instance, configuration information may be delivered using signaling radio bearers (e.g., via Radio Resource Control (RRC) messages), which are specified as Layer 3 control plane messages, for example, in the *.331 series of 3GPP specifications. Physical layer specifications, such as those with Doppler delay resolution and other physical layer specifications, may also be affected by the current implementation, such as the *.201, *.211, *.212, *.213, *.214, and *.216 series of 3GPP specifications.

[0077] The examples may further be or relate to (computer) programs including program code that, when executed on a computer, processor, or other programmable hardware component, performs one or more of the methods described above. Thus, the steps, operations, or processes of the different methods described above can also be executed by a programmed computer, processor, or other programmable hardware component. The examples may also cover program storage devices, such as digital data storage media, which are machine-readable, processor-readable, or computer-readable and encode and / or contain machine-executable, processor-executable, or computer-executable programs and instructions. For example, program storage devices may include or be digital storage devices, magnetic storage media such as disks and tapes, hard disk drives, or optically readable digital data storage media. Other examples may include computers, processors, control units, (field-programmable arrays) ((F)PLAs), (field-programmable gate arrays) ((F)PGAs), graphics processing units (GPUs), application-specific integrated circuits (ASICs), integrated circuits (ICs), or system-on-a-chip (SoC) systems programmed to perform the steps of the methods described above.

[0078] It should further be understood that the disclosure of steps, processes, operations, or functions in the specification or claims should not be construed as implying that these operations must depend on the described order, unless explicitly stated in individual cases or necessary for technical reasons. Therefore, the foregoing description does not limit the execution of steps or functions to a particular order. Furthermore, in other examples, a single step, function, process, or operation may include and / or be decomposed into several sub-steps, functions, processes, or operations.

[0079] If aspects relating to an apparatus or system have already been described, these aspects should also be understood as descriptions of the corresponding method. For example, functional aspects of a block, apparatus, or system may correspond to features of the corresponding method, such as method steps. Therefore, aspects describing a method should also be understood as descriptions of the attributes or functional characteristics of the corresponding block, element, device, or system.

[0080] If aspects relating to an apparatus or system have been described, these aspects should also be understood as descriptions of the corresponding method, and vice versa. For example, functional aspects of a block, apparatus, or apparatus or system may correspond to features of the corresponding method, such as method steps. Therefore, aspects describing a method should also be understood as descriptions of the attributes or functional characteristics of the corresponding block, element, device, or system.

[0081] The following claims are thus incorporated into the detailed description, wherein each claim may stand alone as an independent example. It should also be noted that while in the claims, a dependent claim refers to a specific combination with one or more other claims, other examples may also include combinations of dependent claims with the subject matter of any other dependent or independent claim. Such combinations are thus expressly stated unless, in individual cases, it is stated that no particular combination is intended to be used. Furthermore, the features of a claim should also be included in any other independent claim, even if the claim is not directly defined as dependent on that other independent claim.
