Question: During SCell1 activation (T2), if the subframe (m+8) is subject to interruption, when will the UE send the first CSI report for SCell1?
Option 1: In a subframe immediately after the interruption
Option 2: In a subframe (m+9)
Option 3: At latest in a subframe (m+39) with non-zero CQI index
Option 4: Depending on the next available uplink resource after (m+8)
Explanation: According to specified test requirements for SCell1 activation during T2, if the CSI report in subframe (m+8) was interrupted, the UE shall send the first CSI report for SCell1 in a subframe (m+9), ensuring continuity of reporting despite interruptions.
