Abstract

Methods, apparatus, systems, and articles of manufacture are disclosed for triggerable data driven location determination. An example apparatus is to cause transmission of a sounding reference signal (SRS) configuration to a radio access network (RAN), the SRS configuration for a target device in communication with a radio unit (RU) associated with the RAN. Additionally, the example apparatus is to cause transmission of a value to cause the RAN to compute at least one set of time-of-arrival (TOA) measurements or time-difference-of-arrival (TDOA) measurements for the target device based on detection of SRS data in cellular data received by antennas of the RU from the target device, the at least set one of the TOA measurements or the TDOA measurements based on the SRS configuration. The example apparatus is to estimate a location of the target device based on the at least one set of the TOA measurements or the TDOA measurements.

interface circuitry; machine-readable instructions; and at least one processor circuit to at least one of execute or instantiate the machine-readable instructions to:
determine a sounding reference signal (SRS) configuration for a target device in communication with a radio unit (RU) associated with a radio access network (RAN), the SRS configuration determined based on at least one of an opt-in preference associated with the target device, a state of a power source of the target device, or at least one of an initial or a historical SRS configuration for the target device;
cause transmission of the SRS configuration to the RAN to cause the RAN to compute at least one of time-of-arrival (TOA) measurements or time-difference-of-arrival (TDOA) measurements for the target device based on detection of SRS data in cellular data received by antennas of the RU, the cellular data from the target device, the at least one of the TOA measurements or the TDOA measurements based on the SRS configuration for the target device; and
estimate a location of the target device based on the SRS configuration and the at least one of the TOA measurements or the TDOA measurements.

2 . The apparatus of claim 1 , wherein one or more of the at least one processor circuit is to obtain an identifier, from the RAN, of an antenna that received SRS data, the RU including the antenna.

3 . The apparatus of claim 1 , wherein one or more of the at least one processor circuit is to cause transmission of a request to the RAN to obtain capabilities of the target device.

4 . The apparatus of claim 1 , wherein the SRS configuration includes a frequency with which the location of the target device is to be estimated.

5 . The apparatus of claim 1 , wherein the SRS configuration includes a period for estimating the location of the target device.

6 .
