Question: What is the unit of measurement for the SL-TxPower Information Element, which limits a UE's (User Equipment) sidelink transmission power on a carrier frequency?
Option 1: dBm (Decibel-milliwatts)
Option 2: Watts (W)
Option 3: Milliwatts (mW)
Option 4: Decibels (dB)
Explanation: The correct unit for measuring the UE's sidelink transmission power, as specified for the SL-TxPower Information Element, is dBm (Decibel-milliwatts). This unit is commonly used in telecommunications to express the power of radio signals. The other options are incorrect because while they relate to power measurement, the specific unit defined for SL-TxPower in this context is dBm.
