摘要： The invention proposes a transmitter (such as a gateway or base station, both indoors and outdoors) that actively creates multiple virtual anchors which are associated with certain known reflectors by means of a code, to allow low-capability receivers to be localized more easily. By measuring propagation features, such as, e.g., timing of receipt, of three or more coded beams, low capability receivers - even those with only a single antenna - can be localized, e.g., by the transmitter or by the receivers themselves. The receivers might localize themselves if each beam includes e.g. the location of the anchors, the location of transmitter, and the sending time. This has the advantage that the receivers do not have to send any information back to the transmitter.

摘要： The invention proposes systems and methods for testing on-device machine learning models such as network models of a device based on an access to normal input and output channels, wherein a structure of a model is designed through training such that the model produces distinctive outputs to a given set of test inputs only so long as its internal structure remains in a desired state. Models may be rendered susceptible to such testing via model pre-training with training inputs designed to train the model into an appropriate structure and/or to cause the model to produce a distinctive output if later presented with a certain set of test inputs. If the structure of the model remains within allowable limits, the device will produce a predictable output when tested. If not, the device may be enforced to return to a pre-trained model.

摘要： The invention proposes a system and method for determining and controlling a reconfigurable relay device (e.g., a reconfigurable intelligent surface, RIS, or a smart repeater), wherein the reconfigurable relay device is registered and a wireless communication path is established from a network (e.g. access device) via the reconfigurable relay device to a terminal device. The network registers the reconfigurable relay device and determines parameters needed for its control. The control may be achieved by validated and accepted commands and queries. A relay state of the relay device may be set so that a beam for the wireless communication path is correctly redirected at the terminal device.
