Question: For which purpose is the E-UTRAN TDD RSRP (Reference Signal Received Power) absolute accuracy measurement primarily utilized in a network comprising both UTRAN FDD (Frequency Division Duplex) and E-UTRAN TDD (Time Division Duplex) technologies?
Option 1: Handover between UTRAN FDD and E-UTRAN TDD cells
Option 2: Load balancing within the same RAN (Radio Access Network) technology
Option 3: Inter-RAT (Radio Access Technology) cell selection for LTE to UMTS handovers
Option 4: Optimization of cell coverage in homogeneous E-UTRAN TDD networks
Explanation: The E-UTRAN TDD RSRP absolute accuracy measurement is used for handovers between UTRAN FDD and E-UTRAN TDD, ensuring seamless transition and accurate power measurements across different carrier frequencies and technologies, supporting interoperability and mobility in heterogeneous network environments.
