Hybrid fira-omlox downlink time difference of arrival structure for ultra-wide band ranging

An apparatus comprising:

• one or more memories having computer-readable instructions stored therein;
• and
• one or more processors configured to execute the computer-readable instructions to:
• determine, for each of a plurality of ranging blocks to be used by one of a plurality of anchors in a hybrid FiRa-omlox environment, a corresponding rounding split between corresponding idle ranging rounds and active ranging rounds such, the plurality of anchors including at least one FiRa-compatible anchor and at least one omlox-compatible anchor;
• generate each of the plurality of ranging blocks using the corresponding rounding split;
• and
• send the plurality of ranging blocks to the plurality of anchors.

One or more non-transitory computer-readable media comprising computer-readable instructions, which when executed by one or more processors of a device, cause the device to:

• determine, for each of a plurality of ranging blocks to be used by one of a plurality of anchors in a hybrid FiRa-omlox environment, a corresponding rounding split between corresponding idle ranging rounds and active ranging rounds such, the plurality of anchors including at least one FiRa-compatible anchor and at least one omlox-compatible anchor;
• generate each of the plurality of ranging blocks using the corresponding rounding split;
• and
• send the plurality of ranging blocks to the plurality of anchors.
