Question: In a band combination with more than two band entries for a UE capable of simultaneousRx-Tx, what is the requirement for carriers corresponding to a single band entry in relation to Cell Groups (CGs)?
Option 1: Carriers can belong to any Cell Group (CG) without restriction.
Option 2: Carriers must belong to one specific Cell Group (CG), but the UE cannot indicate supported permutations.
Option 3: Carriers shall belong to one Cell Group (CG), and the UE may indicate supported carrier permutations to CGs.
Option 4: The UE must support all possible carrier permutations across different Cell Groups (CGs) without exception.
Explanation: According to specifications, for UEs capable of simultaneousRx-Tx in band combinations with more than two band entries, carriers from a single band entry are required to belong to one Cell Group (CG). The UE may also indicate which carrier permutations to CGs it supports, allowing for adaptive configuration based on UE capabilities.
