A position offset between a primary coil and a secondary coil of an inductive power transfer pair is determined using a region classifier model and an absolute position model of an operational charging region between the primary coil and the secondary coil. During operation, radio signal information including magnitudes and phase differences is collected from respective radio receivers of a ground transceiver assembly and a vehicle transceiver assembly. The radio signal information and the region classifier model are used to determine whether the vehicle has entered or departed the operational charging region, and the radio signal information and absolute position model are used to determine absolute or relative offset positions of boresights of the primary coil and the secondary coil. A display provides an indication of the absolute or relative offset positions between the boresights of the primary coil and the secondary coil.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may include a main radio and a low-power wake-up radio. While operating in a radio resource control (RRC) inactive state, the UE may use the low-power wake-up radio to monitor for signals.

The UE may use this low-power synchronization signal measurement to determine whether to initiate a small data transmission (SDT) session for communicating the data. The UE may transmit an SDT initiation message if the low-power synchronization signal measurement satisfies a threshold value.
