Power determining method and apparatus

A power determining method, implemented by a terminal device, wherein the power determining method comprises:

• calculating a first additional maximum power reduction (AMPR) based on Long-Term Evolution (LTE) scheduling information and first resource allocation information;
• determining a first LTE power based on the first AMPR;
• accessing a first access device using an LTE access technology;
• accessing a second access device using a New Radio (NR) access technology;
• sending LTE information at the first LTE power;
• obtaining NR scheduling information at a first moment, wherein the first moment is later than a preset calculation start moment of the first LTE power and is earlier than or at a first preset update start moment of the first LTE power;
• determining a second LTE power that is not updated based on the LTE scheduling information and a preset value at the preset calculation start moment of the first LTE power;
• and
• obtaining the first resource allocation information based on the NR scheduling information.
