Question: What is the primary purpose of Inner Loop Power Control in the uplink for a User Equipment (UE) transmitter in a UTRA FDD system?
Option 1: To adjust the downlink transmission power based on UE feedback
Option 2: To enhance the uplink data transfer rate by dynamically allocating more bandwidth
Option 3: To adjust its output power in response to one or more Transmit Power Control (TPC) commands received in the downlink
Option 4: To initiate handover between different base stations without interrupting service
Explanation: Inner Loop Power Control is a mechanism that allows the UE transmitter to dynamically adjust its output power. This adjustment is made in response to TPC commands received from the network in the downlink, ensuring optimal transmission power and minimizing interference. This process is crucial for maintaining efficient and reliable uplink communications in UTRA FDD systems.
