Abstract: An ultra-wideband (UWB) ranging method comprises determining, by a first device, that the first device is within proximity of a second device. Responsive to the determination, the first device negotiates a value to use as a UWB session key for securing UWB communications with the second device. The negotiation occurs via a communication protocol different from a UWB communication protocol. The first device controls a UWB subsystem therein to encrypt information communicated via the UWB subsystem based on the negotiated value of the UWB session key instead of a default value for the UWB session key that is specified in the UWB communication protocol. The information facilitates determining the distance between the first device and the second device.

Abstract: A first user equipment (UE) (102) is configured to establish a first tethered connection (114-1) with a second UE 104 and a second tethered connection (114-2) with at least a third UE (104-2). The first UE (102) identifies a plurality of network slices (118) provided by a network (100). The first UE (102) selects at least a first network slice (118-1) for the second UE (104-1) and selects at least a second network slice (118-2) for the at least third UE (104-2). The first UE (102) wirelessly communicates data for the second UE (104-1) over the at least first network slice (118-1) using a first upstream link (116-1). The first UE (102) wirelessly communicates data for the at least third UE (104-2) over the at least second network slice (118-2) using a second upstream link (116-2). The first upstream link (116-1) and the second upstream link (116-2) are concurrently maintained.
