Question: In conformance testing for User Equipment (UE), what is a capability that the system simulator must provide regarding Uplink Dedicated Channels?
Option 1: Generating Layer 2 Signalling for handover procedures
Option 2: Simulating downlink traffic for throughput measurement
Option 3: Generating Layer 1 Signalling to set UE's Uplink Dedicated Channel power levels to lower values if required
Option 4: Controlling the UE's mobility patterns in a test environment
Explanation: This is correct because the system simulator needs to provide the capability of generating Layer 1 Signalling information specifically for adjusting (lowering) the power levels of the Uplink Dedicated Channels from the UE, relating to uplink power control testing, ensuring the UE can adjust its transmission power as commanded by the network, crucial for efficient network operation and interference management.
