Abstract: Disclosed are techniques for wireless communication. In an aspect, a location server may send, and a base station may receive, a request for positioning information. The base station may send, and the location server may receive, sounding reference signal (SRS) configuration information comprising first information that describes a frame structure used by the base station and second information that identifies, based on the frame structure used by the base station, an available slot with respect to a reference for an aperiodic SRS transmission, wherein an available slot comprises a slot that has enough uplink symbols, flexible symbols, or both, in the time domain for all SRS resources of the aperiodic SRS transmission.

Abstract: The connection between a user equipment (UE) and a base station may be authenticated in the physical layer, and the presence of an unauthorized intervening device may be identified based on predicted measurement values of downlink reference signals and the actual measurement values for the current downlink reference signals. The predicted measurement values are produced based on previous measurements of downlink reference signals that are known to be received from the base station, e.g., after upper layer initial authentication. The predicted values may be for positioning measurements, channel measurements, or velocity or direction of travel measurements, or a combination thereof. A difference between the predicted and actual measurement values indicates that the previously received reference signals and the currently received reference signals are not from the same entity, and thus, an intervening entity is likely present in the communication channel performing a man in the middle or replay attack.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may obtain configuration information that identifies resources for sounding reference signal (SRS) positioning. The UE may transmit, to a reconfigurable intelligent surface (RIS), a plurality of SRS transmissions at different times according to the configuration information. The UE may receive, from the RIS, a plurality of SRS transmissions comprising reflections of the plurality of SRS transmissions to the RIS, wherein each of the plurality of SRS transmissions from the RIS is transmitted at a different angle of departure (AoD) from the RIS. The UE may measure each of the plurality of SRS transmissions from the RIS to produce a plurality of measurements. The UE may perform a positioning operation based on the plurality of measurements.

Abstract: A user equipment (UE) detects signals transmitted by one or more attacking devices that interfere with downlink signals from base stations. The UE measures the angle of arrival (AoA) and power information of the interfering signals and sends an interference report to a serving base station. The base station may receive interference reports for the interfering signals from multiple UEs. One or more base stations may determine the identity of the attacking device based on the position of the attacking device determined using the information from the interference report and known positions of devices connected to the network. The one or more base stations may bar access to the network by the attacking device once the attacking device is identified and/or may report the attacking device.
