Question: What is the maximum number of Component Carriers (CCs) that can be aggregated for a User Equipment (UE) in Carrier Aggregation (CA), considering both Downlink (DL) and Uplink (UL)?
Option 1: 8 CCs for DL and 4 CCs for UL
Option 2: 16 CCs for DL only
Option 3: 16 CCs for DL and 16 CCs for UL
Option 4: 32 CCs for both DL and UL
Explanation: According to the Carrier Aggregation (CA) specifications, a UE can be configured with up to 16 Component Carriers (CCs) for Downlink (DL) and up to 16 CCs for Uplink (UL). This allows for flexible configuration of CA capabilities depending on the UE's capabilities and network requirements.
