Question: In LTE Positioning Protocol (LPP), what is the primary purpose of the "Sensor-Error" Information Element (IE) in communication between a location server and a target device?
Option 1: To transmit positioning data from the target device to the location server for location calculation.
Option 2: To negotiate the type of positioning method (e.g., GPS, Wi-Fi, cellular) to be used by the target device.
Option 3: To convey error reasons related to sensor functionality from one entity (location server or target device) to the other.
Option 4: To acknowledge successful receipt of location assistance data by the target device.
Explanation: The "Sensor-Error" IE is specifically designed for exchanging information about errors encountered with sensor functionality. This is crucial for troubleshooting and ensuring the accuracy of positioning data. By conveying these error reasons, both the location server and the target device can take appropriate corrective actions, highlighting the importance of this IE in maintaining the integrity of the LTE Positioning Protocol.
