Abstract
An electronic device receives an indication of a number of physical resource blocks and subcarrier spacing of at least a portion of a transmission channel and determines a dynamic transmission bandwidth, or receives an indication of a modulation coding scheme of the transmission channel and determines a modulation order. The electronic device transmits, using a transmitter, a signal over at least the portion of the transmission channel based on the dynamic transmission bandwidth being less than or equal to a threshold bandwidth, or the modulation order not corresponding to an additional power backoff, using a first power based on a maximum output power capacity of the electronic device and a maximum power reduction. Otherwise, the electronic device transmits the signal over at least the portion of the transmission channel at a second power based on the maximum output power capacity, the maximum power reduction and the additional power backoff.
