1. A device, comprising:
at least one antenna;
at least one radio coupled to the at least one antenna, wherein the at least one radio comprises circuitry supporting at least two radio access technologies (RATs); and
a processing element coupled to the at least one radio;
wherein the processing element is configured to cause the device to:
scan an arbitration channel for a first time period, wherein the arbitration channel mirrors activity on a UWB channel;
wherein, when, based on the scanning, the arbitration channel is determined to be in use, the processing element is configured to cause the device to:
align timing to the arbitration channel; and
arbitrate for UWB channel access at a subsequent arbitration event; and
wherein, when, based on the scanning, that the arbitration channel is determined to not be in use, the processing element is configured to cause the device to:
perform, on the arbitration channel, a first channel access procedure; and
perform, on the UWB channel, UWB communications during a UWB channel transmission opportunity.
