Description

Technical field The disclosure relates to a method for processing data associated with a radar device. The disclosure further relates to a device for processing data associated with a radar device. Summary Some examples relate to a method, such as a computer-implemented method, for processing data associated with a radar device for a mobile unit, e.g., a vehicle, and/or for an infrastructure unit, e.g., a road infrastructure unit, such as a roadside unit, wherein the method comprises: determining the presence of a management node for controlling media access related to radar signal transmissions and, based on the determination, controlling the operation of the radar device. In some examples, this may allow for flexible adaptation of the radar device's operation, e.g., to changing conditions in the radar device's environment, such as the presence or absence of the management node. The method can be understood as a procedure, in particular for operating or controlling a radar device, performed by a unit contained within the radar device. In some examples, controlling media access may involve assigning and/or allocating resources in connection with radar signal transmission and/or reception operations. In some examples, the radar device may be designed to perform detection, e.g., by performing at least one of the following actions: a) transmitting detection signals, e.g., radar signals for detection, or b) receiving at least some of the detection signals, which may interact with one or more objects in the vicinity of the radar device (e.g., by scattering and/or reflection). In some examples, controlling media access in connection with radar signals may include at least one of the following steps: a) controlling media access in connection with radar signal transmission operations, or b) controlling media access in connection with radar signal reception operations, or c) controlling media access in connection with radar signal transmission and reception operations. In some examples, the radar device may be configured for wireless communication with at least one other device, e.g., at least one other radar device, e.g., in accordance with or based on at least one planned or accepted standard such as 4G or 5G or 6G, or another planned or accepted standard, e.g., using a wireless, for example, cellular communication system, for example, of type 5G or 6G or based on 5G or 6G, or the like. In some examples, data exchange between the radar device and at least one other device can be carried out, at least temporarily, via a network device, e.g., a base station, e.g., gNB, of the wireless communication system. In some examples, data exchange between the radar device and at least one other device can be carried out, at least temporarily, via direct device-to-device communication, e.g., using a sidelink interface. In some examples, this enables device-to-device communication even in the absence of network coverage. In some examples, the radar device may be designed to exchange information with one or more other devices, such as one or more other radar devices, via a wireless, for example cellular, communication system, such as 5G or 6G or based on 5G or 6G or the like, e.g. to coordinate the operation of the radar devices, e.g. with regard to detection. In some examples, the radar device may be designed to perform at least one radar procedure, for example for detection, using signals from the wireless, for example cellular, communication system, for example of type 5G or 6G or based on 5G or 6G or the like. In some examples, the radar device may, at least temporarily, use signals from a wireless communication system, such as reference signals from a wireless communication system according to any planned or accepted standard, to perform the detection. In some examples, however, the radar device may, at least temporarily, use specific radar signals to perform the detection, such as signals other than those of a wireless communication system. In some examples, FMCW signals may be used for detection by the radar device. In some examples, controlling media access related to radar signals may include controlling media access related to radar signals for detection using FMCW signals. In some examples, the radar device may be designed to perform integrated communications and sensing (ICAS). In some examples, the same transmitter and/or receiver, e.g., a transceiver set, may be used for both communications and sensing, e.g., for ICAS. In some examples, determining includes at least one of the following steps: a) determining that the management node is present, e.g., in the vicinity of the radar device, or b) determining that the management node is not present, e.g., in the vicinity of the radar device. In some examples, the procedure involves listening to a communication channel to determine whether a signal, such as an announcement message, from the management node (e.g., a management node that may be located in the vicinity of t
