Disclosed is a method for performing downlink time difference of arrival (DL-TDoA) by an ultra-wide band (UWB) device that includes selecting at least one active ranging round from a ranging block based on at least one of location information or motion information about the UWB device, transferring, to a UWB sub system, a command including information about the at least one active ranging round, and performing a DL-TDoA operation based on the information about the at least one active ranging round.

A wireless device can use a channel occupancy time (COT) to reserve a spectrum for sidelink positioning operations in a certain time interval. In some examples, multiple wireless devices can share the same COT for performing sidelink positioning and/or ranging operations using unlicensed or shared spectrum. Some aspects of the disclosure provide various processes for handling scenarios when channel access of the unlicensed spectrum is unsuccessful.

A solution for providing user equipment (UE) location information during an emergency call (e.g., an E911 call) includes: detecting an emergency call originating from the UE; determining a location of the UE; based on at least detecting the emergency call originating from the UE, transmitting the location of the UE across a cellular network to an emergency monitoring node (e.g., a public safety answering points (PSAP) and/or a gateway mobile location center (GMLC)); and based on at least detecting the emergency call originating from the UE, transmitting the location of the UE across a packet data network (e.g., the internet, using a data plan) to the emergency monitoring node. This provides an alternate path for the location information, and some examples use a larger set of location information sources. In some examples, during the emergency call, based on available battery power, the UE location information may be updated.
