Question: What is the primary purpose of providing Data Bit Assistance to a Global Navigation Satellite System (GNSS) receiver in a User Equipment (UE) within an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)?
Option 1: To enhance location accuracy by utilizing data bits for sensitivity assistance and facilitating precise time recovery.
Option 2: To manage UE positioning protocol stacks for efficient resource allocation.
Option 3: To optimize E-UTRAN cell site selection based on GNSS satellite geometry.
Option 4: To authenticate UE access to the E-UTRAN network using GNSS credentials.
Explanation: Data Bit Assistance is crucial for improving the performance of GNSS receivers in UEs. By providing information about data bits or symbols transmitted by a GNSS satellite, it enables two key enhancements: sensitivity assistance (data wipe-off), which helps in reducing interference and enhancing signal detection, and time recovery, which improves the accuracy of location determination. This directly impacts the UE's ability to provide precise location services within the E-UTRAN network.
