Question: During T2, if a UE's PCell is interrupted during SCell1 activation in FDD mode, which of the following subframe ranges are **NOT** allowed for interruption?
Option 1: (m+12) to (m+14)
Option 2: (m+20) to (m+24)
Option 3: (m+30) to (m+34)
Option 4: (m+10) to (m+14) and (m+20) to (m+24)
Explanation: According to test requirements, during T2, PCell interruption during SCells activation in FDD mode is not allowed outside specific ranges. Allowed ranges for FDD are (m+5) to (m+9), (m+15) to (m+19), (m+25) to (m+29), and (m+35) to (m+39). Option 4 correctly identifies ranges ((m+10) to (m+14) and (m+20) to (m+24)) not explicitly permitted for interruption during SCell1 activation in FDD mode.
