Question: For an IAB-DU (Integrated Access and Backhaul - Donor Unit) Type 1-H, what is the basis for determining the upper limit of the total power dynamic range in a specified reference condition?
Option 1: The average power for single Resource Block (RB) transmission with PDSCH (Physical Downlink Shared Channel) only.
Option 2: The OFDM (Orthogonal Frequency Division Multiplexing) symbol power when transmitting on all RBs at maximum output power, akin to a Base Station (BS).
Option 3: The total power consumed by the IAB-DU during idle mode in the operating band.
Option 4: The minimum transmit power required for successful handover between two IAB-DUs.
Explanation: According to specifications, the upper limit of the dynamic range for an IAB-DU Type 1-H is defined by the OFDM symbol power when a Base Station (BS) transmits on all Resource Blocks (RBs) at its maximum output power, representing peak transmission capacity and setting the upper boundary of the total power dynamic range.
