Hello Experts,
Can you provide an explanation of the difference between Carrier Aggregation, Dual Connectivity and Dynamic Spectrum Sharing?
And how the final output difference can be seen in any RF planning tool?

In CA, only one UE identity is used in all component carriers . But in DC, UE is identified by different C-RNTIs in MCG and SCG.Where DSS is a key technology that dynamically allocates spectrum resources between LTE and 5G NR within the same frequency band.
