Description

Power reporting method, communication device and storage medium Technical Field The present application relates to the field of communication technology, and in particular to a power reporting method, communication equipment and storage medium. Background Art The MPR (Maximum Power Reduction) of the DFT-S-OFDM waveform is 2 dB lower than that of the CP-OFDM waveform, which means that the maximum uplink transmit power of the terminal device on the carrier is different when using different waveforms, that is, P CMAX It is different. From the current protocol, we know that the terminal equipment reports the power headroom (PH) and the maximum uplink transmit power P on the corresponding carrier through PHR (Power Headroom Report). CMAX The base station takes these two parameters as important considerations for its scheduling. It can be seen that if the waveform of the uplink transmission can be switched dynamically, the maximum uplink transmission power P of the terminal device on the carrier CMAX and power margin PH will change.
