Question: In a 5G E-UTRA network, what is the primary purpose of a UE having a standalone GNSS (Global Navigation Satellite System) receiver as defined by its radio access capabilities?
Option 1: To enhance uplink transmission power for better voice quality
Option 2: To facilitate seamless handovers between LTE and 5G NR cells
Option 3: To provide the network with UE's detailed location in RRC_CONNECTED mode only
Option 4: To enable providing detailed location information in both RRC measurement reports and logged measurements, especially useful in NTN (Non-Terrestrial Network) cell operations
Explanation: A standalone GNSS receiver in a UE is primarily utilized for location services, allowing the device to provide its precise location to the network. This capability is particularly beneficial in scenarios where traditional cellular-based location methods may not be effective, such as in NTN cell operations (e.g., satellite communications). The detailed location information can be shared through RRC measurement reports and logged measurements, even when the UE is in the RRC_IDLE state, enhancing location services in various network conditions.
