Question: What is the primary condition for a UE to transmit a valid CSI report for an activated SCell after receiving the activation command, considering the SCell activation delay?
Option 1: The UE must have completed the RRC procedure and obtained a valid TA command for the target PCell within the same slot.
Option 2: The UE can transmit the CSI report no later than in slot n+ Ndirect, where Ndirect includes various delays with a minimum adjustment.
Option 3: The UE must interrupt any ongoing transmission on the PCell for at least Tinterrupt duration before transmitting the CSI report on the activated SCell.
Option 4: The UE is required to send an acknowledgement to the eNodeB before transmitting the CSI report for the activated SCell, not included in the Ndirect calculation.
Explanation: This option correctly captures the essence of the test requirement for SCell activation delay, emphasizing that the UE must transmit a valid CSI report within a specified time frame after considering all relevant delays.
