Question: Which of the following is NOT one of the standard Location Services (LCS) methods specified for UTRAN?
Option 1: Cell ID (CID) positioning method
Option 2: OTDOA (Observed Time Difference of Arrival) positioning method
Option 3: A-GNSS (Assisted Global Navigation Satellite System) based positioning methods
Option 4: Hybrid Automatic Repeat Request (HARQ) Feedback method
Explanation: The correct answer is Option 4 because HARQ (Hybrid Automatic Repeat Request) Feedback is a method related to error correction and retransmission in wireless communication systems, not a positioning method for Location Services (LCS). In contrast, the other options (Cell ID, OTDOA, and A-GNSS) are recognized positioning methods.
