1. A computer-implemented method, comprising:
transmitting, by a first device, a packet via a narrowband (NB) signal to a second device, the packet comprising information indicating a time period for reception of a plurality of fragments, respectively, via an ultra-wideband (UWB) signal; and
transmitting, by the first device, a first fragment of the plurality of fragments to the second device via the ultra-wideband signal, the first fragment comprising at least one intermediary base sequence, the at least one intermediary base sequence being aperiodic and comprising a first set of first sequences and a second set of second sequences, the first sequences being periodic within the first set and the second sequences being periodic within the second set.
