AI Technical Summary
Technical Problem
In terminal devices, increasing the number of antennas to improve received signal power is difficult, especially due to size limitations and power consumption issues, resulting in insufficient received signal power and affecting communication performance.
Method used
The network device instructs the terminal device on the phase factor of the reference signal port, and the terminal device adjusts the phase of the antenna port to superimpose the signals and improve the received signal power.
Benefits of technology
Without increasing the number of antennas, improve the received signal power of the terminal device and reduce power consumption and signaling overhead.

Abstract
The application provides a signal transmission method, a communication device, a storage medium and a program product. The method comprises the following steps: a second communication device sends first indication information to a first communication device, the first indication information is used for indicating phase factors corresponding to M reference signal ports, the M reference signal ports correspond to M antenna ports, M is an integer greater than or equal to 1, correspondingly, the first communication device receives the first indication information, and then adjusts the phases corresponding to all or part of the M antenna ports based on the first indication information, so that when the first communication device receives a downlink signal through the M antenna ports, the signals can be superimposed on each other, and the power of the received signal is improved.
