Question: In LTE Positioning Protocol (LPP), what is the primary purpose of the "NR-ECID-Error" Information Element (IE) in communication between a location server and a target device?
Option 1: To transmit location coordinates from the target device to the location server.
Option 2: To negotiate the protocol version for NR E-CID positioning.
Option 3: To convey error reasons related to NR E-CID positioning, either from the location server to the target device or vice versa.
Option 4: To initiate a new positioning request from the location server to the target device.
Explanation: The correct answer is Option 3 because the "NR-ECID-Error" IE is specifically defined for communicating error reasons associated with NR E-CID (Enhanced Cell ID) positioning. This facilitates troubleshooting and handling of errors that may occur during the positioning process, ensuring effective communication between the location server and the target device regarding any issues with NR E-CID positioning attempts.
