1. A computer-implemented method, comprising:
determining, by a first subsystem of a first device, parameter data for a ranging round, the parameter data indicating a first time for initiating the ranging round, and the first time associated with a first time domain for performing ranging;
transmitting, by the first subsystem to a second subsystem of the first device, the parameter data, the first subsystem and the second subsystem being communicatively connected via a data bus of the first device;
determining, by the second subsystem, a second time based at least in part on the first time, the second time associated with a second time domain for performing narrowband (NB) signaling;
transmitting, by the first device via a narrowband signal, an advertisement packet that indicates the second time; and
initiating, by the first device, the ranging round at the first time.
