Question: What is the condition for aggregate power control tolerance for Category NB1 and NB2 UEs, with respect to maintaining output power in non-contiguous transmission?
Option 1: When uplink power control parameters are dynamic.
Option 2: When α is set to 0 and uplink power control parameters are constant.
Option 3: When the UE transmission is contiguous.
Option 4: When the UE is operating in a specific frequency band.
Explanation: The correct answer requires understanding of the conditions under which Category NB1 and NB2 UEs maintain their output power in non-contiguous transmission. This involves recognizing that α must be set to 0, and uplink power control parameters as defined in TS 36.213 must remain constant.
