Question: For a User Equipment (UE) to support coverage-based paging carrier selection, as specified in E-UTRA standards, which of the following conditions must be met regarding its supported categories?
Option 1: The UE must support at least one category from both LTE and NR (New Radio) families.
Option 2: The UE's supported category is irrelevant to coverage-based paging carrier selection.
Option 3: The UE must exclusively support categories above MBB (Mobile Broadband) categories.
Option 4: The UE must support at least one ue-Category-NB (Narrow Band) category.
Explanation: According to E-UTRA specifications, a UE must support any ue-Category-NB to utilize coverage-based paging carrier selection. This ties the functionality to supporting Narrow Band categories for efficient network resource utilization and power saving.
