A gain adjustment control method, device and apparatus, and a non-transitory computer-readable storage medium are disclosed. The method may include: calculating energy of a full-bandwidth physical downlink shared channel (PDSCH) transmission signal in an intermediate frequency digital domain or a baseband digital domain according to a set calculation period; determining a gain control adjustment parameter according to the calculated energy of the full-bandwidth PDSCH transmission signal; and controlling and adjusting a gain of a receiver according to the determined gain control adjustment parameter and a gain adjustment rule.
