Question: What is the primary purpose of providing "Acquisition Assistance" to a Global Navigation Satellite System (GNSS) receiver in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)?
Option 1: To enhance location security by encrypting GNSS signals
Option 2: To reduce power consumption of the UE during positioning
Option 3: To expedite the acquisition of GNSS signals by providing pertinent satellite and signal characteristics
Option 4: To enable the UE to function as a GNSS signal repeater for nearby devices
Explanation: Acquisition Assistance is crucial for speeding up the process by which a GNSS receiver detects and locks onto available satellites. By providing details such as visible satellites, reference time, expected code-phase, Doppler shift, and search windows, the UE can quickly narrow down its search parameters, thereby reducing the time and computational resources needed to acquire a satellite signal. This is particularly important in cellular networks where minimizing the time to first fix (TTFF) improves user experience for location-based services.
