Techniques are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. For example, a first device may transmit a packet via an NB signal to a second device, whereby the packet comprises information indicating a time period for reception of a plurality of fragments, respectively, via a UWB signal. The first device may then transmit a first fragment of the plurality of fragments to the second device via the UWB signal, whereby the first fragment comprises an intermediary base sequence, the intermediary base sequence being aperiodic and comprising a first set of first sequences and a second set of second sequences. In some embodiments, the intermediary base sequence may contain at least one gap interval that may be used to identify a signature of the link between the first device and the second device.
