16 Claims

1. A method performed by a transmission terminal in a communication system, the method comprising:

determining whether neural network coefficient information related to the transmission terminal is stored in a reception terminal;

transmitting, to the reception terminal, neural network structure information related to the transmission terminal based on a determination that the neural network coefficient information is stored in the reception terminal;

generating a wideband signal based on inputted voice;

generating a narrowband signal by down-sampling the wideband signal; and

transmitting, to the reception terminal, the narrowband signal.
