BACKGROUND In a communication system, a network device typically configures a terminal to report Power Headroom Reports (PHRs) for one or more Physical Uplink Shared Channels (PUSCHs), respectively, so that the terminal reports PHRs for the PUSCH transmission channels, thereby enabling the network device to perform corresponding scheduling for the terminal's uplink transmission based on the PHRs reported by the terminal. Optionally, when triggering the PHR reporting, the terminal usually needs to determine whether the PHR is a virtual PHR or an actual PHR based on the transmission situations of the PUSCH transmission channels. Optionally, the transmission situation corresponding to the virtual PHR is where the PUSCH transmission channel is not transmitted or the signal of the PUSCH transmission channel is not transmitted, and the transmission situation corresponding to an actual PHR is where the PUSCH transmission channel is actually transmitted or the signal of the PUSCH transmission channel is actually transmitted.
