Abstract: Certain aspects of the present disclosure provide techniques for secure digital key derivation for a ranging session between a first device (e.g., a user equipment (UE)) and a second device (e.g., a vehicle). According to certain aspects, a first device maintains a secure ranging in a secure element (SE) at the first device. The first device further fetches, from the SE, one or more other keys derived from the secure ranging key. The first device further uses the one or more other keys to secure a ranging session between the first device and a second device.

Abstract: Certain aspects of the present disclosure provide techniques for the coexistence of wireless telecommunication devices (e.g., 4G, 5G, and/or 6G devices) and UWB devices operating in a same frequency band. A method generally includes receiving, from a first user equipment (UE), first signaling indicating an initiation of a first ultra-wideband ranging session between the first UE and an ultra-wideband device; determining a location of the first UE after receiving the first signaling; and performing one or more first interference mitigation processes configured to reduce channel interference in a first ultra-wideband channel used for the first ultra-wideband ranging session based on, at least, the location of the first UE.
