Question: What is the purpose of configuring a UE to report multiple CSI entries in a CSI report based on two or more sub-configurations?
Option 1: To enable the gNB to perform beamforming on the UE.
Option 2: To assist the gNB on muting transceivers and/or adapting transmission power.
Option 3: To allow the UE to switch between different frequency bands.
Option 4: To enable the gNB to prioritize traffic for multiple UEs.
Explanation: The correct answer is Option 2 because configuring a UE to report multiple CSI entries in a CSI report based on two or more sub-configurations helps the gNB to adapt its transmission power and/or mute transceivers, which is essential for efficient spatial and power domain adaptation. This feature enables the gNB to optimize its transmission parameters based on the UE's feedback, leading to improved network performance and reduced interference.
