Description

Technical Field

[0001] This disclosure relates to the field of wireless communications. Embodiments relate to methods for improving handover lists for user equipment connected to a cell, methods for using a cell, devices, vehicles, and computer programs, and more particularly, but not exclusively, to concepts for improving handover lists, such as improving a user equipment's handover list by a cell. 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, wide spectrum 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 identified as key functions to support an increasingly connected transportation ecosystem.

[0003] US 9622124B2 discloses a system comprising one or more processors communicatively coupled to a mobile communication network. The one or more processors are configured to identify a neighbor table including a handover priority list of target base stations, the handover priority list being prioritized based on the relative signal strength or quality of service of the target base station being obvious to mobile devices within the occupied area of ​​the source base station. The one or more processors are further configured to determine an implicit handover plan based on at least one of the mobile device's geographic location data, user information associated with the mobile device, and network resource data. The one or more processors are further configured to update the handover priority list in the neighbor table based on the implicit handover plan to provide improved allocation of network resources and improved signal strength or quality of service to multiple mobile devices within the mobile communication network over a duration.

[0004] US 9923622B2 discloses a mobile communication system installed in a mobile vehicle, having anticipated tracking area information for a route along which the vehicle is expected to travel. User equipment associated with a mobile relay node is provided with the list, and if the vehicle's movement corresponds to the stored list, a tracking area update is not performed. In cases where prior knowledge of the route is unavailable, the mobile relay node is configured with a fixed tracking area and a fixed radio cell, such that the associated user equipment does not detect changes in the tracking area or radio cell, and therefore does not perform a tracking area update toward the network, or the network does not need to control the user equipment's mobility while having a radio connection to the network.

[0005] However, for mobile communication devices (e.g., buses, trains, vehicles, etc.) that act as relay systems (RS) for user equipment (UEs) (e.g., as new cells between in-cabin or out-of-cabin mobile devices), avoiding unwanted connections between the UE and other communication devices (e.g., other cells) may remain a challenging task. Therefore, there may be a need to prevent the UE from instantaneously switching (e.g., transitioning) between different cells (e.g., standard cells, such as network entities, RSs, etc.) to establish a connection to an unwanted cell (e.g., RS, stationary cell, etc.).

[0006] Therefore, it was found that UE connectivity can be improved by refining the UE's handover list by the cell (especially by considering the possibility of mobile cells and / or UE movement). This allows the UE to avoid unwanted handovers between different cells, such as handovers occurring within a short period of time. Summary of the Invention

[0007] The example provides a method for a user equipment connected to a cell to improve its handover list. The method includes obtaining information about multiple communication devices in the environment and generating a handover list. Furthermore, the method includes transmitting the handover list to the cell and transmitting dynamic information about its own state (e.g., mobility state) to the cell. The method also includes receiving an improved handover list from the cell. Therefore, the UE can avoid unwanted handovers between different cells by receiving an improved handover list. For example, the cell can generate the improved list based on the UE's dynamic information and the handover list, because the UE may have improved information about the multiple communication devices included in the handover list compared to other UEs.

[0008] In the example, at least one of the multiple communication devices is a mobile communication device, and the information obtained in relation to the at least one mobile communication device includes dynamic information. The method may then further include transmitting the dynamic information relating to the at least one mobile communication device to the cell. This allows the cell to be notified of dynamic information belonging to a mobile communication device (e.g., a vehicle providing relay services).

[0009] In the example, the improved handover list may include information relating to connection parameters between the user equipment and each of the multiple communication devices. The method may then further include selecting a communication device to connect to from the multiple communication devices based on the connection parameters. This allows the UE to select a desired communication device, for example, to achieve a desired service.

[0010] In the example, the connection parameters consist of at least one element from the group consisting of: usage time, signal quality, location of use, radio access technology and capability. Thus, the UE can receive relevant information about potential connections to determine whether a connection is appropriate.

[0011] In the example, information about multiple communication devices is obtained by receiving collaborative sensing data. This allows the UE to be notified about multiple communication devices in a simple manner.

[0012] The example relates to a method for improving a handover list in a cell connected to a user equipment (UE). The method includes receiving a handover list comprising multiple communication devices from the UE and obtaining dynamic information related to the state of the UE. Furthermore, the method includes obtaining information related to the multiple communication devices in the cell's environment and using the dynamic information of the UE and the obtained information related to the multiple communication devices to generate an improved handover list. The method also includes transmitting the improved handover list to the UE. In this way, the cell can provide the UE with an improved handover list, which avoids unwanted handovers between different cells.

[0013] In the example, at least one of the multiple communication devices is a mobile communication device. The method may then further include obtaining dynamic information relating to the at least one mobile communication device and using the dynamic information of the at least one mobile communication device to generate an improved handover list. In this way, the cell can take into account dynamic information belonging to a single mobile communication device (e.g., a vehicle providing relay services).

[0014] In the example, the improved handover list includes information related to connection parameters, which are at least one element from the group consisting of: usage time, signal quality, location for use, radio access technology and capabilities. In this way, the cell can provide the UE with relevant information about potential connections to determine whether a connection is appropriate.

[0015] In the example, dynamic information relating to the user equipment and / or at least one mobile communication device is obtained by: using one or more sensors of the cell; and / or receiving information from the user equipment and / or at least one mobile communication device. Thus, the cell can determine the required information for generating an improved handover list, and / or may receive the required information, for example, from the UE, the mobile communication device, or both.

[0016] In the example, information relating to multiple communication devices is obtained by: using one or more sensors of the cell to determine information relating to the multiple communication devices; and / or receiving information from the multiple communication devices. Thus, the cell can determine and / or receive information relating to the multiple communication devices in an appropriate manner.

[0017] In the example, the cell is mobile. This allows the cell to account for its own movement in order to generate a handover list that includes the cell.

[0018] In this example, the cell acts as a relay system. This allows the UE to be provided with preferred connectivity.

[0019] 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.

[0020] The example further provides vehicles that include the equipment described above.

[0021] 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

[0022] The following are some examples of devices and / or methods, described by way of example only and with reference to the accompanying drawings, wherein... Figure 1 Examples of methods for user equipment are shown; Figure 2 Examples of methods for cells are shown; and Figure 3 A block diagram of the device is shown. Detailed Implementation

[0023] 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.

[0024] Throughout the description of the accompanying drawings, the same or similar reference numerals denote the same or similar elements and / or features, which may be implemented identically or in modified form while providing the same or similar function. For clarity, the thickness of lines, layers, and / or areas in the drawings may also be enlarged.

[0025] When 'or' is used to combine two elements A and B, it is understood to disclose all possible combinations, i.e., only A, only B, and A and B, unless otherwise expressly specified in the individual case. 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.

[0026] If the singular form such as “a” (a, an) and “the” is used and the use of a single element is not explicitly or implicitly mandatory, other examples may use several elements to achieve the same functionality. If the functionality is described below as being implemented using multiple elements, other examples may use a single element or a single processing entity to achieve the same functionality. It is further understood that the terms “include” and / or “comprise” describe, when used, the presence of the specified feature, integer, step, operation, process, element, component, and / or group 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.

[0027] Figure 1 An example of method 100 for a user equipment is shown. The UE is connected to a communication device (e.g., a cell), and method 100 is used to improve a handover list. Method 100 includes obtaining 110 information related to multiple communication devices in the environment and generating 120 a handover list. Furthermore, method 100 includes transmitting the handover list to the cell 130 and transmitting dynamic information related to its own state (e.g., mobility state) to the cell 140. Method 100 also includes receiving the improved handover list from the cell 150. By receiving the improved handover list, the UE is notified of the improved possibility of establishing a connection to one of the multiple communication devices (e.g., to a cell acting as an RS, a mobile cell, etc.).

[0028] For example, the handover list may include extremely small cells with limited coverage areas, which are not known to the UE. Therefore, the UE can establish a connection to the extremely small cell, but if the UE is moving, it is required to terminate the connection to the extremely small cell and connect to another cell. An improved handover list generated from the cells takes into account the small coverage area of ​​the extremely small cells and the UE's movement, and therefore the extremely small cells may not be included in the improved handover list. This avoids unwanted connections from the UE to extremely small cells.

[0029] A UE can communicate with a communication device (e.g., a cell) in a mobile communication system. For example, the UE and the communication device can communicate within / via the mobile communication system. The mobile communication system may include multiple transmission points and / or base stations operable to transmit radio signals to the UE. In this example, the mobile communication system may include the UE and the communication device.

[0030] Communication devices (e.g., cells) can be located in fixed or stationary parts of a network or system. Communication devices can correspond to remote radio 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. A communication device can be a wireless interface of a wired network that enables the transmission and reception of radio signals to and from a UE (such as a UE or UE-compliant device). Such radio signals may conform to, for example, radio signals standardized by 3GPP, or generally conform to one or more systems listed above. Therefore, communication devices can correspond to NodeBs, eNodeBs, BTSs, access points, etc.

[0031] 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, respectively. 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., the communication device), that is, it can be associated with a cell to enable the exchange of data between mobile devices using dedicated channels, connections, or links within the network and the coverage area of ​​the associated cell.

[0032] Typically, a UE is a device capable of wireless communication. However, in particular, the UE and / or communication device (cell) can be mobile, such as a UE suitable for being carried by a user. For example, within the meaning of the corresponding communication standard used for mobile communication, the UE can be a user terminal (UT) or user equipment (UE). For example, the 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, the communication device can be an RS included in a vehicle. For example, the UE and communication device can be configured to communicate in a cellular mobile communication system. Accordingly, the UE and communication device can be configured to communicate in a cellular mobile communication system, such as in a Sub-6 GHz-based cellular mobile communication system (covering the band between 500 MHz and 6 GHz) or in an mmWave-based cellular mobile communication system (covering the band between 20 GHz and 60 GHz). For example, the UE and communication device can be configured to communicate in a mobile communication system / cellular mobile communication system. Typically, a mobile communication system may correspond to one of the standardized mobile communication networks of the 3rd Generation Partnership Project (3GPP), where the terms mobile communication system and mobile communication network are used synonymously. A mobile communication system may 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 Evolution of GSM Data Rate (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.

[0033] Additionally, the UE / communication device may be adapted for communication via non-cellular communication systems or configured to communicate via non-cellular communication systems, such as via device-to-device vehicle communication systems 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)). In particular, the UE and communication device can be adapted for communication 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 communication between 5.9 GHz and 7.1 GHz (for WiFi in the 6 GHz band).

[0034] The connection between the UE and the communication device can be a wireless connection, such as a 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 (e.g., using a carrier frequency of up to 7.5 GHz). For example, the wireless connection between the UE and the communication device can be initiated using protocols of a mobile communication system or using a short-range communication system, such as via the wireless local area network described above.

[0035] As is evident from the examples above, although communication between the UE and the communication device is conducted via a mobile communication system, additional and / or alternative communications between the UE and the communication device (e.g., if the communication device is a vehicle) can be conducted via a vehicle communication system. Such communication can be performed directly, for example, by means of device-to-device (D2D) communication. The specifications of a vehicle communication system can be used to perform such communication. 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 such D2D communication include 802.11p, 3GPP systems (4G, 5G, NR and above), etc.

[0036] A handover list (also known as a neighbor list) includes communication devices (e.g., cells) that are checked more frequently than the rest of the communication device, and therefore handovers with cells in the handover list are more likely. Optionally, a UE may be allowed to connect only to cells included in the handover list (as is the case in Global System for Mobile Communications).

[0037] Dynamic information may be time-dependent and / or change over time. For example, the UE may be mobile (e.g., a vehicle including the UE), and therefore dynamic information may reflect the movement of the mobile UE, such as its speed of movement, planned departure (e.g., at a red traffic light or at a bus stop, etc.).

[0038] Information relating to multiple communication devices can be obtained by: using the UE's sensors to determine information and / or by, for example, receiving information from multiple communication devices. For example, the UE (e.g., a vehicle) may use a wide range of airborne sensor data types (including radar sensor data and lidar sensor data), but may also use visual correlation sensors such as imaging devices and IR sensors, as well as ultrasonic sensors, to determine the location of the communication devices in order to determine information used to determine the predicted performance.

[0039] The handover list (120) and / or dynamic information relating to its own state (130) can be transmitted to the cell via any appropriate message (e.g., broadcast, multicast, or unicast). Therefore, the handover list / dynamic information can be transmitted in the desired manner, for example, using broadcast messages. For instance, if the UE is a vehicle and the cell is another vehicle (e.g., an RS), the handover list can be transmitted via V2X communication.

[0040] The 140-degree improved handover list can be received from the cell via any appropriate message (e.g., via broadcast, multicast, or unicast). Therefore, it is possible to receive handover list / dynamic information as desired, for example, using unicast messages.

[0041] By transmitting handover lists and dynamic information to the cell, the cell is able to generate an improved handover list. The improved handover list differs from the original handover list. For example, communication devices included in the original handover list may not be included in the improved handover list; for instance, very small cells, as described above, may be deleted by the cell to generate the improved handover list. For example, the cell may be aware of additional communication devices not included in the list of multiple communication devices, and therefore the cell may add these additional communication devices to the handover list to generate the improved handover list.

[0042] For example, the UE could be a vehicle approaching the tunnel. Therefore, the UE can receive information from other vehicles that may have already entered the tunnel, which is why the cell might not be aware of these other vehicles. However, these other vehicles can provide relay services, allowing the UE to use them while passing through the tunnel. Finally, the UE can generate a handover list (120) that includes other vehicles and, for example, stationary cells outside the tunnel. This handover list can be transmitted (130) to the cell, and the cell can identify that stationary cells have no coverage area inside the tunnel. Furthermore, based on the transmitted dynamic information (140), the cell can identify that the UE is approaching the tunnel and will enter the tunnel at some time.

[0043] In the first example, a quiescent cell can be removed from the handover list to generate an improved handover list. The UE can retrieve the improved handover list (which only includes other modes of transportation), and thus the UE can establish a connection to one of these other modes of transportation. This avoids unwanted handovers from quiescent cells to other modes of transportation.

[0044] In the second example, the cell may know from a dataset, for example, that another communication device (e.g., a tunnel cell) is located inside the tunnel, which can be used by every vehicle entering the tunnel. Therefore, the cell can remove all communication devices from the handover list and add the tunnel cell to the handover list, generating an improved handover list. The UE can receive 150 new handover lists and, through the improved handover list, know that the tunnel cell will be available. This avoids unwanted handovers from other vehicles to the tunnel cell.

[0045] In the example, at least one of the multiple communication devices is a mobile communication device, and the information obtained in relation to the at least one mobile communication device includes dynamic information. Method 100 may further include transmitting the dynamic information related to the at least one mobile communication device to the cell. For example, the at least one mobile communication device may be a first vehicle, and the UE may be a second vehicle, both traveling in the same direction. Furthermore, the first vehicle may include a better antenna system than the second vehicle, and therefore the first vehicle may provide relay services to other communication devices such as the second vehicle. The second vehicle may generate a 120 handover list (which includes the first vehicle and other stationary cells), and may transmit a 130 handover list and dynamic information related to its own state and dynamic information related to the second vehicle to the cell. The cell may recognize that the first and second vehicles are traveling at the same speed in the same direction. Furthermore, the cell may recognize that stationary cells from the handover list are unsuitable for the second vehicle. Therefore, the cell may generate an improved handover list by removing all stationary cells from the handover list. In this way, the second vehicle (UE) can be forced to connect to the first vehicle, which reduces unwanted handovers between different cells (communication devices).

[0046] For example, the UE can determine dynamic information related to multiple mobile communication devices and can transmit the dynamic information of said multiple mobile communication devices to the cell. The cell can consider only mobile communication devices that can move in the same direction as the UE and optionally at the same speed. In this way, the improved handover list can include only mobile communication devices that move at the same speed as the UE, which can improve the connection time between the UE and mobile communication devices from the improved handover list.

[0047] In the example, the improved handover list includes information relating to connection parameters between the user equipment and each of the multiple communication devices. Method 100 may then further include selecting a communication device to connect to from the multiple communication devices based on the connection parameters. In the example, the connection parameters are at least one element from the group consisting of: usage time, signal quality, location for use, radio access technology, capability, latency rate, signal strength, predicted QoS (pQoS) download rate, etc. This allows the UE to select a desired communication device to connect to from the improved handover list, for example, to use a desired service, such as video streaming, video telephony, gaming applications, etc.

[0048] In the example, information relating to multiple communication devices is obtained by receiving cooperative sensing data. This simplifies communication, for example, if the UE is a vehicle (or is included by a vehicle). V2X communication between the UE and the vehicle for receiving information relating to multiple communication devices can be performed via wireless local area network (WLAN) technology and can operate directly between vehicle-to-vehicle (V2V) and / or vehicle-to-infrastructure (V2I), forming a vehicle-to-vehicle ad hoc network because the two V2X senders are within each other's range. Messages such as Cooperative Sensing Messages (CAM) or Basic Safety Messages (BSM) and Distributed Environment Notification Messages (DENM) can be used for communication between the UE and the vehicle. Other roadside infrastructure-related messages include Signal Phase and Timing Messages (SPAT), In-Vehicle Information Messages (IVI), and Service Request Messages (SRM).

[0049] Further details and aspects will be described 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 the following descriptions (e.g.) Figure 2-3 One or more optional additional features corresponding to one or more aspects of one or more example descriptions.

[0050] Figure 2 An example of method 200 for a cell is shown. The cell is connected to the UE (e.g., as for...). Figure 1 The UE mentioned above), and method 200 for improving the handover list. For example, the cell is for Figure 1 The UE is connected to a communication device (corresponding cell). Method 200 includes receiving 210 a handover list including multiple communication devices from the user equipment, and obtaining 220 dynamic information related to the state of the user equipment (e.g., mobility state). Method 200 may further include obtaining 230 information related to multiple communication devices in the cell environment, and using the dynamic information of the user equipment and the obtained information related to the multiple communication devices to generate 240 an improved handover list. Method 200 may further include transmitting 250 the improved handover list to the user equipment. The cell may be targeted at... Figure 1 The peer of the UE. For example, a cell can be a stationary cell such as a base station, a vehicle acting as an RS, or another UE acting as an RS.

[0051] Receiving the 210 handover list from the user equipment can be performed via any appropriate message (e.g., via broadcast, multicast, or unicast). Therefore, it is possible to receive the handover list in the desired manner, for example, using a broadcast message.

[0052] Obtaining 220 dynamic information related to the mobility state of the user equipment and / or obtaining 230 information related to multiple communication devices can be done by: using the cell's sensors to determine information and / or by, for example, receiving information from multiple communication devices and / or from the UE. For example, a cell (e.g., a vehicle) may use a wide range of airborne sensor data types (including radar sensor data and lidar sensor data), but also uses visual correlation sensors such as imaging devices and IR sensors, as well as ultrasonic sensors, to determine the location of communication devices in order to determine information used to determine the predicted performance.

[0053] The improved handover list can be transmitted to the UE via any appropriate message (e.g., broadcast, multicast, or unicast). Therefore, the improved handover list can be transmitted as desired, for example, using unicast messages. For instance, if the UE is a vehicle and the cell is another vehicle (e.g., RS), the improved handover list can be transmitted via V2X communication.

[0054] For example, regarding Figure 1 The aforementioned method enables the cell to generate an improved handover list of 240, which can reduce or even avoid unwanted handovers between different communication devices for the UE. For example, the cell may know the coverage area of ​​each stationary cell included in the handover list and has obtained 220 dynamic information related to the UE's state, such as movement speed. Therefore, the cell can determine each cell in the handover list (a connection to said cell is only possible for a certain period of time below a threshold, such as a few seconds). The cell can then remove all these determined cells to generate the improved handover list of 240. Thus, the UE can receive the improved handover list, which includes only communication devices (cells) to which a connection is possible for a minimum time, taking into account the UE's movement.

[0055] In the example, at least one of the multiple communication devices is a mobile communication device. Method 200 may further include obtaining dynamic information related to the at least one mobile communication device and using said dynamic information to generate an improved handover list. For example, if the mobile device is moving in the same direction as the UE, the cell may only consider the mobile communication device. This can avoid unwanted connections, such as between departing vehicles.

[0056] In the example, the improved handover list may include information related to connection parameters, which are at least one element from the group consisting of: usage time, signal quality, location for use, radio access technology and capabilities. In this way, the UE can learn the connection parameters and select the desired communication device based on the desired service, which can then be used to perform the desired action.

[0057] In the example, dynamic information relating to a user equipment and / or at least one mobile communication device can be obtained by using one or more sensors in the cell and / or receiving information from a user equipment and / or at least one mobile communication device. In the example, information relating to multiple communication devices can be obtained by using one or more sensors in the cell and / or receiving information from multiple communication devices. This allows for the simple determination of dynamic information and information relating to multiple communication devices.

[0058] In the example, the cell is mobile. In the example, the cell acts as a relay system.

[0059] Further details and aspects will be described in conjunction with the embodiments described above and / or below. Figure 2 The examples shown may include those combined with the proposed concepts or above. Figure 1 ) and / or the following (e.g. Figure 3 One or more optional additional features corresponding to one or more aspects described in the one or more examples described above.

[0060] 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-described actions (e.g., for...). Figure 1 The method for the UE and / or the above (e.g., for the UE) described above Figure 2 The method described above is used for cells.

[0061] For example, device 30 can be a UE, wherein the interface is configured to communicate with the cell. Alternatively, device 30 can be a cell, wherein interface 32 is configured to communicate with the UE.

[0062] like Figure 3As 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, any component for processing (such as a processor), a computer, or a programmable hardware component that can operate with correspondingly adapted software. Similarly, the functionality of the 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 through the interfaces and / or any interactions that may involve the interfaces can be controlled by the processing circuitry 34. For example, device 30 may be included by a means of transportation. For example, the means of transportation may be a land vehicle, such as a road vehicle, automobile, motor vehicle, off-road vehicle, motor vehicle, bus, robotaxi, van, truck, or truckload vehicle. Alternatively, the means of transportation may be any other type of vehicle, such as a train, subway train, boat, or ship. For example, the proposed concept is applicable to public transportation (trains, buses) and future moving parts (e.g., robotaxis).

[0063] In an 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.

[0064] In the example, one or more interfaces 32 can be used to obtain, receive, transmit, or provide analog or digital signals or information, such as any connector, contact, pin, register, input port, output port, conductor, lane, etc., which allows the provision or receipt of signals or information. The interface can be wireless or wired, and it can be configured to exchange (i.e., transmit or receive signals) information with other internal or external components. One or more interfaces 32 may include additional components used to enable communication between vehicles. Such components may 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.

[0065] Further details and aspects will be described in conjunction with the embodiments described above. Figure 3 The examples shown may include those in conjunction with the proposed concepts or the above descriptions (e.g.) Figure 1-2 One or more optional additional features corresponding to one or more aspects of one or more example descriptions.

[0066] The aspects and features described in a particular example relative to the previous example may also be combined with one or more other examples to replace the same or similar features of that other example or to introduce features into the other example.

[0067] Examples may conform to or even be included in certain standard specifications, such as those defined by 3GPP. For instance, configuration information may be conveyed using signaling radio bearers, for example, via Radio Resource Control (RRC) messages, which are specified as Layer 3 control plane messages in the *.331 series of 3GPP specifications, for example. Physical layer specifications may also be influenced by current embodiments (e.g., the *.201, *.211, *.212, *.213, *.214, and *.216 series of 3GPP specifications), for example, by means of Doppler delay resolution and other physical layer specifications.

[0068] Examples may further be or relate to (computer) programs, which include program code for performing one or more of the methods described above when the program is executed on a computer, processor, or other programmable hardware component. Therefore, the steps, operations, or processes of the different methods described above may also be performed by a programmed computer, processor, or other programmable hardware component. Examples may also cover program storage devices, such as digital data storage media, which are machine, processor, or computer readable and encoded and / or contain machine-executable, processor-executable, or computer-executable programs and instructions. Program storage devices may include, for example, 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 systems-on-a-chip (SoCs) programmed to perform the steps of the methods described above.

[0069] It is further understood that the disclosure of certain steps, processes, operations, or functions in this description or claims should not be construed as implying that these operations necessarily depend on the stated order, unless otherwise expressly stated in the individual case or necessary for technical reasons. Therefore, the foregoing description does not limit the execution of certain 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, sub-functions, sub-processes, or sub-operations.

[0070] If aspects are described relative to an apparatus or system, then those aspects should also be understood as describing the corresponding method. For example, a block, device, or functional aspect of an apparatus or system may correspond to a feature of the corresponding method, such as method steps. Accordingly, aspects described relative to a method should also be understood as describing a corresponding block, element, property, or functional feature of the corresponding apparatus or system.

[0071] If aspects are described relative to an apparatus or system, these aspects should also be understood as describing the corresponding method, and vice versa. For example, a block, device, or functional aspect of an apparatus or system may correspond to a feature of the corresponding method, such as method steps. Accordingly, aspects described relative to a method should also be understood as describing a corresponding block, element, property, or functional feature of the corresponding apparatus or system.

[0072] The following claims are thus incorporated into the detailed description, wherein each claim may stand alone as a separate example. It should also be noted that while in the claims, a dependent claim indicates a specific combination having one or more other claims, other examples may also include combinations of the subject matter of the dependent claim with the subject matter of any other dependent or independent claim. Such combinations are thus explicitly stated unless stated in individual cases where a particular combination is not anticipated. Furthermore, the features of any other independent claim should also be included, even if that claim is not directly defined as dependent on that other independent claim.

[0073] The aspects and features described in a particular example relative to the previous example may also be combined with one or more other examples to replace the same or similar features of that other example or to introduce features into the other example.
