Description

Technical Field

[0001] Embodiments of the present disclosure relate to vehicles, apparatus, computer programs and methods for mitigating interference to UWB applications. In particular, but not limited to, embodiments relate to concepts for mitigating interference to UWB applications in a vehicle. Background Art

[0002] In vehicles, communication plays an increasingly important role. To this end, vehicles can use several communication technologies. Therefore, vehicles can be equipped with various communication technologies, such as WLAN (wireless local area network) technology, low-power Bluetooth (BLE) and ultra-wideband (UWB). In particular, vehicles can use WLAN technology according to the Wi-Fi 6E (6GHz) standard of the Institute of Electrical and Electronics Engineers (IEEE), which is designed to operate in an unlicensed band between 1 and 7.125 GHz (including 2.4 and 5 GHz bands and the much wider 6 GHz band). However, the use of Wi-Fi 6E can cause (in-band) interference to the vehicle's UWB communication. Interference may cause data loss and / or malfunctions. In practice, for example, interference may cause functions using UWB (e.g., locking / unlocking the vehicle and / or presence detection via a smartphone) to not work correctly or not work at all.

[0003] In some applications of WLAN technology, it is specified that the WLAN router applies the "Listen Before Talk" (LBT) technology, that is, the WLAN router checks whether the WLAN channel to be used is free of interference before using the WLAN channel. However, the transmission power of UWB communication is lower than that of WLAN signals, and the sensitivity of WLAN devices is too low to detect UWB communication when LBT is applied. As a result, the WLAN device cannot detect UWB communication using LBT. Therefore, LBT of WLAN devices does not help to reduce interference to UWB applications.

[0004] Therefore, improved concepts for mitigating interference to UWB applications may be needed. Summary of the invention

[0005] This need is met by the subject matter of the accompanying independent and dependent claims.

[0006] Embodiments are based on the discovery that the timing of UWB applications, for example, the transmission and / or reception times of a UWB communication session, can be predefined. A basic idea according to embodiments of the present disclosure is to use knowledge about the transmission and / or reception times to mitigate interference of radio transmitters (not involved in the UWB application) to UWB applications. For example, the concepts disclosed herein propose adjusting the timing of a radio transmitter so that one or more transmissions of the radio transmitter overlap less in time with the transmission and / or reception times of the UWB application. According to another aspect of the present disclosure, mitigation measures are used to adjust the transmission channel of the radio transmitter so that the transmissions of the radio transmitter overlap less in time with the UWB channel of the UWB application to reduce interference. For example, one idea is to reduce the transmission channel to a certain extent (for example, to a bandwidth of up to 20 MHz) so that the transmissions of the radio transmitter can be filtered out.

[0007] Embodiments of the present disclosure provide a method for mitigating interference of a radio transmitter of a vehicle to a UWB application of the vehicle. The method includes obtaining information about the UWB application. In addition, the method includes adjusting the radio transmitter based on the information about the UWB application so as to at least reduce interference to the UWB application. In this way, data / information loss, malfunction and / or failure of the UWB application can be reduced.

[0008] In practice, adjusting the radio transmitter may include generating a message indicating information about the UWB application and transmitting the message to the radio transmitter for adjusting the radio transmitter. In this way, the method may be applied by any device other than a radio transmitter. In an embodiment, for example, the method may be applied / performed by a UWB device that may also be used for UWB applications.

[0009] In some embodiments, the information about the UWB application includes information about at least one time slot of the UWB application, and adjusting the radio transmitter includes adjusting the transmission time of the radio transmitter based on the information about the time slot so as to at least reduce interference. This, for example, causes the transmission of the radio transmitter to overlap less or not overlap at all with the transmission and / or reception for the UWB application. In this way, interference with the UWB application can be further reduced or ideally avoided.

[0010] Alternatively or additionally, adjusting the transmitter includes adjusting a transmission channel of the radio transmitter based on information about the UWB application. In this way, the overlap of transmissions of the radio transmitter with transmissions and / or receptions of the UWB application in terms of use frequency can be reduced, for example, such that the bandwidth of the transmissions of the radio transmitter is adjusted so that the transmissions interfere less with the UWB application.

[0011] In particular, adjusting the transmission channel may include switching the transmission channel. In practice, a plurality of different transmission channels may be used for transmission of the radio transmitter. By switching the transmission channel, the overlap with the UWB channel of the UWB application may be at least reduced or ideally avoided, so that interference with the UWB application is reduced or even avoided.

[0012] Alternatively or additionally, adjusting the transmission channel comprises reducing a bandwidth of the transmission channel based on the information about the UWB application. In this way, switching the transmission channel may be omitted or interference may be further reduced.

[0013] In some embodiments, reducing the bandwidth includes reducing the bandwidth to a maximum of 20 MHz. In some applications, interfering radio signals with a bandwidth of up to 20 MHz may be filtered out by the UWB device. Thus, reducing the bandwidth to a maximum of 20 MHz may allow transmissions of radio transmitters to be filtered out. In this way, switching transmission channels may be omitted, for example, in order to use a preferred transmission channel.

[0014] Thus, the method may further include filtering out interference within the reduced bandwidth of the UWB application.

[0015] Another embodiment provides a method for a radio transmitter for a vehicle and a method for mitigating interference of a radio transmitter of a vehicle to a UWB application of the vehicle. The method includes receiving a message indicating information about the UWB application and adjusting the radio transmitter based on the information about the UWB application to at least reduce interference. For example, the radio transmitter can be adjusted in a manner described in more detail above or below. In this way, interference with the UWB application can be reduced, so that malfunctions and / or failures are reduced or ideally avoided.

[0016] In some embodiments, the radio transmitter comprises a wireless local area network (WLAN) device.

[0017] Further embodiments provide a computer program having a program code for performing at least one of the methods of the preceding claims when the computer program is executed on a computer, a processor or a programmable hardware component.

[0018] Further embodiments provide an apparatus comprising one or more interfaces for communication and a data processing circuit configured to control the one or more interfaces and to perform one of the methods presented herein using the one or more interfaces.

In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intermediate elements. Similarly, words such as "between," "adjacent," etc. should be interpreted in a similar manner.

[0030] Vehicles can be equipped with different technologies for communication and other functions. For example, according to the standards of the Car Connectivity Consortium (CCC-TS-101, Version 1.0 / 1.1), vehicles can be equipped with BLE as well as UWB to enable digital vehicle access, i.e., access to the vehicle using a personal communication device (e.g., mobile phone, tablet, smartwatch, personal computer, etc.). Similarly, vehicles can be equipped with WLAN technology. However, WLAN technology operating according to the IEEE's Wi-Fi 6E (6GHz) standard may interfere with UWB applications such as ranging, presence detection and / or digital vehicle access. In particular, Wi-Fi 6E may in practice interfere with UWB channel 5 with a center frequency of 6489.6 MHz and a bandwidth of 499.2 MHz. Therefore, the vehicle's UWB applications (such as UWB ranging) may be interfered with by WLAN signals from wireless access points or routers on the (same) vehicle or other vehicles.

[0031] When communicating via WLAN, LBT is applied to mitigate interference. However, WLAN devices are not sensitive enough and the transmission power of UWB signals is too weak to mitigate the interference of WLAN signals to UWB applications.

[0032] Therefore, there may be a need for improved concepts for mitigating interference of radio signals to UWB applications. This need may be met, at least in part, by the subject matter of the appended independent and dependent claims. The claimed subject matter will be described in more detail below with reference to the accompanying drawings.

[0033] Figure 1 A flow chart schematically illustrating an embodiment of a method 100 for mitigating interference of a radio transmitter of a vehicle to a UWB application of the vehicle is shown. The radio transmitter is for example a WLAN device.

[0034] In the context of the present disclosure, UWB may be understood as a technology for transmitting information over a wide bandwidth (greater than 500 MHz), or as an antenna transmission that transmits a signal bandwidth exceeding the smaller of 500 MHz or 20% of the arithmetic center frequency (as defined by the Federal Communications Commission and the International Telecommunication Union). A UWB application may be any function, service, or other application that uses UWB. In practice, method 100 may be applied in a vehicle, and the UWB application may include a UWB communication session between a vehicle and a user device, as described in more detail below. In other applications, the UWB application may include a UWB radar.

[0035] As can be seen from the flow chart, method 100 includes obtaining information about UWB applications. To this end, a device that executes or controls UWB applications can provide information about UWB applications. Information about UWB applications, for example, includes information about UWB channels and / or time slots used for UWB applications. A time slot is, for example, a time window in which a UWB transmitter, receiver, and / or transceiver transmits or receives a UWB signal for executing a UWB application, respectively. A UWB channel can be understood as a frequency band used for UWB applications.

[0036] Interference is caused, for example, by the superposition of UWB signals for UWB applications with other signals from radio transmitters with similar frequencies. In practice, interference occurs, for example, as described above, the Wi-Fi 6E signal of a radio transmitter (WLAN device) interferes with the UWB signal in UWB channel 5. Interference may cause UWB applications to fail. In practice, for example, UWB ranging is inaccurate or fails.

[0037] Thus, the method 100 provides adjusting 120 a radio transmitter based on information about the UWB application such that at least interference to the UWB application is reduced. Adjusting 120 the radio transmitter comprises, for example, adjusting the transmission of the radio transmitter in terms of timing and transmission channel of the transmission.

[0038] In practice, for example, the transmission time of the radio transmitter is adjusted based on the timing information about the UWB application so that interference is reduced. In some applications, the information about the UWB application includes, for example, information about the time slot of the UWB application. The information about the time slot indicates, for example, the time of one or more time slots. In practice, the information includes, for example, information about the start, end and / or duration of the upcoming / next time slot and / or the interval between subsequent time slots. In addition, the information about the time slot may include or correspond to a timetable indicating the timing of one or more time slots. The transmission time may be a time period, a start time or an end time of the transmission of the radio transmitter. By adjusting the transmission time, for example, the overlap with the UWB signal diagram in time can be at least reduced or ideally avoided. In an embodiment, for example, the transmission time of one or more transmissions / signals is adjusted so that the radio transmitter does not transmit any signal during the time slot. In doing so, for example, one or more transmissions of the radio transmitter may be rescheduled or skipped / omitted so that overlap is reduced, thereby reducing interference. To this end, (the clocks of) the UWB device and the radio transmitter may be (at least approximately) synchronized so that the adjustment of the transmission time and the information about the time slots of the UWB application are based on (approximately) a similar time reference. In practice, for a time slot of about 24 ms for UWB ranging, a synchronization accuracy of 1 to 2 ms may be sufficient to substantially reduce interference. Those skilled in the art will recognize that the proposed concept may also be applied to multiple time slots of UWB applications.

[0039] Alternatively or additionally, the transmission channel of the radio transmitter (i.e., the frequency band used for transmissions of the radio transmitter) is adjusted based on the information about the UWB application. For example, the information about the UWB application indicates which UWB channel is used for the UWB application, and the transmission channel is adjusted such that the overlap with the used UWB channel is reduced. In this way, interference can be further reduced. Those skilled in the art will also recognize that in this way, interference can be reduced to such an extent that further adjustments, such as timing adjustments (see above), can be omitted.

[0040] In some embodiments, adjusting the transmission channel includes switching the transmission channel. In practice, for example, a radio transmitter has multiple different transmission channels available. In an embodiment, the radio transmitter is, for example, a WLAN device, and multiple WLAN channels with different center frequencies and bandwidths are available. Therefore, in order to switch the transmission channel, for example, the WLAN channel is changed. In practice, the WLAN channel may belong to different WLAN bands, for example, the 2.4 GHz band, the 5 GHz band, and the 6 GHz band. Thus, switching the transmission channel (WLAN channel) may also include switching the transmission band (WLAN band). In doing so, a transmission channel with less or no overlap with the bandwidth of the UWB signal of the UWB application can be selected / used, thereby reducing interference with the UWB application. In an embodiment, for example, UWB channel 5 is used for UWB applications, and the radio transmitter operates in a WLAN channel in the 6 GHz band according to Wi-Fi 6E. Since UWB channel 5 and the 6 GHz band overlap, interference may occur. Therefore, according to the proposed concept, the radio transmitter can switch to another WLAN channel, for example, a channel in the 5 GHz or 2.4 GHz frequency band, so as to reduce or avoid interference with the UWB signal. A person skilled in the art who has benefited from the present disclosure will recognize that the concept can also be applied to other UWB channels and / or transmission channels of the radio transmitter.

[0041] Alternatively or additionally, adjusting the transmission channel comprises reducing the bandwidth of the transmission channel based on the information about the UWB application. In this way, for example, the bandwidth can be reduced so that the transmission channel overlaps less or no longer with the UWB channel of the UWB application, thereby reducing interference. In this way, switching of the transmission channel can be omitted, for example, to maintain a preferred transmission channel.

[0042] Furthermore, the bandwidth can be reduced to such an extent that the transmissions of the radio transmitters within the transmission channel can be filtered out, or interference with the UWB application is acceptable (e.g., if the UWB application is still used for the desired purpose). For example, in UWB applications, interfering signals with a bandwidth of up to 20 MHz can be filtered out. Thus, the bandwidth is reduced, for example, to a maximum of 20 MHz, so that the transmissions of the radio transmitters can be filtered out, thereby reducing interference. In particular, reducing the bandwidth allows maintaining the preferred transmission channel.

[0043] A skilled person having the benefit of this disclosure will recognize that the proposed concepts may be implemented in different entities or devices. In some applications, for example, the radio transmitter is controlled and adjusted externally, i.e., by a device separate from the radio transmitter. For example, the radio transmitter is adjusted by a UWB device or any other control device for a UWB application. In other applications, the radio transmitter is configured to self-adjust based on information about the UWB application. In this case, the UWB device may provide information about the UWB application to the radio transmitter, and the radio transmitter may self-adjust based on the information about the UWB application.

[0044] Thus, adjusting 120 the radio transmitter may include generating a message indicating information about the UWB application and transmitting the message to the radio transmitter to adjust the radio transmitter. In other applications, the UWB device may provide instructions to the radio transmitter, and the radio transmitter adjusts according to the instructions.

[0045] Thus, the proposed concept can also be implemented in a complementary correlation method for a radio transmitter of a vehicle, as described below with reference to Figure 2 More elaborated.

[0046] Figure 2 A flow chart schematically illustrating an embodiment of a radio transmitter for a vehicle and a method 200 for mitigating interference of a radio transmitter of a vehicle to a UWB application of the vehicle is shown.

[0047] Thus, the method 200 includes receiving 210 a message indicating information about a UWB application, and adjusting 220 a radio transmitter based on the information about the UWB application to at least reduce interference.

[0048] For example, in some embodiments, a radio transmitter of a WLAN device receives a message for a UWB application from a UWB device. In practice, the UWB device, for example, thereby provides the radio transmitter with information indicating the timing and / or frequency band (UWB channel) applied to the UWB application. As described above, the information about the UWB application, for example, includes information about one or more time slots and / or UWB channels used for the UWB application, and the timing and / or transmission channel is adjusted so as to at least reduce interference with the UWB application, as described above.

[0049] Reference Figure 3 The proposed concepts are explained in more detail by exemplary use cases schematically illustrated in FIG.

[0050] like Figure 3As indicated, the exemplary use case relates to a UWB application of a vehicle 350. In the illustrated use case, the UWB application provides for communication between a UWB device 330 of the vehicle 350 and a user device 310 in a UWB communication session (indicated by a double arrow 340). In addition to the UWB device 330, the vehicle 350 is also equipped with a radio transmitter 320. In the illustrated example, the radio transmitter 320 corresponds to a WLAN device. In other applications, the radio transmitter 320 may also be another UWB transmitter. Figure 3 As indicated in , the WLAN device 320 is configured to transmit a WLAN signal 322. However, the WLAN signal may interfere with the UWB communication between the vehicle 350 and the user device 310. The UWB communication session 340 is used, for example, for ranging, i.e., determining the distance and / or position of the user device 310 relative to the vehicle 350. In other examples, the proposed concepts are applicable to other UWB applications, such as UWB radar, etc.

[0051] The UWB communication session 340 may include a one-way or two-way exchange of one or more signals between the user device 310 and the UWB device 330, respectively. In the example shown, the UWB communication session 340 is used, for example, to exchange time-based signals for time-of-flight-based ranging and / or to transmit digital keys. For example, interference with WLAN signals may cause ranging results to be less accurate and / or fail.

[0052] For time-of-flight based ranging, in practice, the UWB device 330 and the user equipment 310 may be at least approximately (with a tolerance of 1 to 2 ms) synchronized to obtain information about the timing of the UWB application and a similar time reference for transmission time adjustments.

[0053] According to the proposed concept, the WLAN device 320 is adjusted so that the interference to the UWB communication session 340 is at least reduced. To this end, the UWB device 330 transmits a message including information about the UWB application to the WLAN device. In this way, the UWB device 330 provides the WLAN device 320 with information about the UWB channel and / or one or more time slots in which the UWB device 330 and the user device 310 exchange signals for the UWB application. In practice, the UWB device 330 can transmit information about the UWB application via "out-of-band" communication, that is, communication outside the shared frequency band (UWB channel, transmission channel). In practice, the UWB device 330 transmits information about the UWB application, for example, via Bluetooth or a wired connection, for example, via the bus system of the vehicle 350. In other embodiments, "in-band" communication can also be used, thereby using a shared frequency band. In some embodiments, the same communication method used to send information or messages about the UWB application can be used for time synchronization of the UWB device 330 and the WLAN device 320.

[0054] Optionally, the message includes instructions configured to block / prevent the WLAN device 320 from transmitting any signal during the time slot and / or in the UWB channel based on the information about the UWB application. Therefore, the message may be referred to as a "blocking message".

[0055] Then, the WLAN device 320 is adjusted based on the message. In doing so, for example, the WLAN device 320 is adjusted so that it does not transmit signals in the time slot and / or UWB channel indicated by the message. To this end, the WLAN device 320 uses information about the UWB application or takes action according to the instructions of the message, respectively. In practice, the WLAN device 320 can omit, skip and / or reschedule a planned transmission and / or change the transmission channel, as explained in more detail above. In this way, the interference of the WLAN signal 322 to the UWB communication session 340 can be reduced and / or the WLAN signal 322 with reduced bandwidth can be filtered out, so that data / information loss is reduced or avoided, and ranging is successful.

[0056] In the application, for example, preferably, the UWB channel 5 and the time slot with a predefined length (e.g., 24 ms) and the predefined interval between the subsequent time slots can be used for ranging and digital vehicle access. Thus, the WLAN device 320 can use or switch to a WLAN channel that does not overlap or overlaps less with the UWB channel 5 and / or can be adjusted so that the WLAN device 320 transmits the WLAN signal 322 in the interval between the subsequent time slots for the UWB application to reduce interference with the UWB application. For coordination, the UWB device 330 can also be synchronized with the WLAN device 320.

[0057] A skilled person having benefit of the present disclosure will recognize that the proposed concept can also be applied to any number of (synchronized) radio transmitters, such as WLAN devices, and / or any number of UWB devices. Likewise, the proposed concept can be applied to any UWB application. In particular, the proposed concept can also be applied to any application not related to a vehicle.

[0058] It should also be noted that the proposed concept can be applied to any radio transmitter that may interfere with UWB applications. In practice, this can be another UWB device or a system including a combination of UWB devices and WLAN devices.

[0059] The proposed concept can also be implemented in a computer program (product) having a program code for performing at least one method in the preceding claims when the computer program is executed on a computer, a processor or a programmable hardware component. In practice, the proposed concept can also be implemented in separate interrelated computer programs, for example, separate computer programs for UWB device 330 and WLAN device 320.

[0060] As will be appreciated by those skilled in the art, the proposed concept may also be implemented in corresponding devices, as described below with reference to Figure 4 More detailed explanation.

[0061] Figure 4 Shown is a block diagram schematically illustrating an embodiment of an apparatus 400 implementing the proposed concept.

[0062] from Figure 4 It can be seen that the apparatus 400 includes one or more interfaces 410 for communication and a data processing circuit 420 configured to control the one or more interfaces 410. The data processing circuit 420 is also configured to control the one or more interfaces 410 and use the one or more interfaces 410 to perform embodiments of the method 100 or 200.

[0063] In an embodiment, one or more interfaces 410 may include components for communicating with a vehicle or another server. To this end, one or more interfaces 410 may include or correspond to any components for obtaining, receiving, transmitting or providing analog or digital signals or information, for example, any connector, contact, pin, register, input port, output port, conductor, channel, etc. that allows providing or obtaining signals or information. The interface may be wireless or wired, and may be configured to communicate with other internal or external components, that is, to transmit or receive signals, information. One or more interfaces 410 may include other components to achieve corresponding communications, which may include transceiver (transmitter and / or receiver) components, such as one or more low noise amplifiers (LNA), one or more power amplifiers (PA), one or more duplexers, one or more diplexers, one or more filters or filtering circuit systems, one or more converters, one or more mixers, correspondingly adapted radio frequency components, etc. One or more interfaces 410 may be coupled to one or more antennas, which may correspond to any transmission and / or reception antennas, such as horn antennas, dipole antennas, patch antennas, sector antennas, etc. The antennas may be arranged in defined geometric configurations, such as uniform arrays, linear arrays, circular arrays, triangular arrays, uniform field antennas, field arrays, combinations thereof, and the like.

[0064] like Figure 4As shown in , one or more interfaces 410 are coupled to a data processing circuit 420. In an embodiment, the data processing circuit 420 may include any component for processing information according to the proposed method. The data processing circuit 420 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 operating with corresponding adapted software). In other words, the functions of the data processing circuit 420 may also be implemented in software, which is then executed on one or more programmable hardware components. Such hardware components may include a general-purpose processor, a digital signal processor (DSP), a microcontroller, etc.
