Question: In OTDOA (Observed Time Difference of Arrival) measurements for Cat-M UEs in CE Mode A, what is the minimum required rate of correct RSTD (Reference Signal Time Difference) measurement events for each neighbor cell during repeated tests?
Option 1: At least 75% with reported RSTD within a specified range
Option 2: At least 80% with reported RSTD within a specified range
Option 3: At least 85% with reported RSTD within a specified range
Option 4: At least 90% with reported RSTD within the RSTD reporting range (e.g., between RSTD_0000 and RSTD_12711)
Explanation: This question assesses understanding of OTDOA measurement reliability in LTE networks, specifically for Cat-M UEs in CE Mode A. The correct answer reflects the requirement for a high accuracy rate of RSTD measurements to ensure reliable location services, crucial for precise UE positioning, impacting services like emergency calls and location-based services.
