Abstract: Example embodiments of the present disclosure relate to attacker detection in ambient IoT. An apparatus receives at least one signal which is at least associated with a trick tag signal transmitted from a terminal device. The apparatus determines a number of attackers of a tag detection session based on the at least one signal. The apparatus transmits, to a network device, attacker information at least comprising the number of attackers. In this way, the NR element is enabled to identify and report jamming activities to the network in time. Therefore, the tag detection integrity can be guaranteed.

Abstract: A node receives and measures reference signals for determining positioning information corresponding to a UE. The node applies a function to the measured reference signals to form an output corresponding to a fixed set of input features and determines the positioning information of the UE using the output. The node sends a measurement report, including indication of the positioning information, from the node toward a further node. A further node sends to the node indication of a function to be used by the node to apply to positioning reference signals to form an output of a fixed set of input features used to determine positioning information for a UE. The further node receives a measurement report including at least indication of the positioning information based at least on the positioning reference signals and the function and updates at least the function based at least on the measurement report.

Abstract: Systems, methods, apparatuses, and computer program products for duty-cycle based positioning sounding reference signals. A method may include receiving, at a user equipment, configuration information of at least one periodic positioning sounding reference signal. The configuration information may include at least one time interval and at least one transmission resource associated with the at least one time interval. The method may also include transmitting the at least one periodic positioning sounding reference signal to a network entity based on the configuration information. The at least one periodic positioning sounding reference signal may be in a first transmission status or a second transmission status in accordance to the at least one time interval. The at least one time interval may occur periodically.

Abstract: Example embodiments of the present disclosure relate to positioning enhancements. A first device receives, from a second device, first configuration information of a first set of passive radios for transmitting a plurality of first target signals in response to receiving a plurality of first reference signals from a third device. The first device receives, from the third device, at least one first reference signal. Upon receiving the at least one first reference signal, the first device receives, based on the first configuration information, the plurality of first target signals from the first set of passive radios. The first device transmits, to the second device, measurements related to the at least one first reference signal and the plurality of first target signals for positioning the first device. In this way, non-LoS detection for positioning is enabled, and the positioning accuracy is improved.
