Signaling techniques using fragmented and multi-partitioned UWB packets

Techniques are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. In one example, a first device may transmit a first packet via an NB signal to a second device, whereby the first packet comprises information indicating to the second device a time period for reception of a second (UWB) packet. In this example, the second packet may comprise a first partition and a second partition, whereby the first partition comprises a first plurality of fragments and the second partition comprising a second plurality of fragments. The respective fragments of each plurality of fragments may be transmitted via a UWB signal. The first device may then transmit the first plurality of fragments, and then subsequently transmit the second plurality of fragments to the second device, the first and second pluralities respectively being associated with different fragment types.
