1. A method for transmitting a signal using a time offset by a base station in a time-asynchronous nonorthogonal multiple access (TA-NOMA) system, the method comprising:
identifying a first bit stream for a first user equipment (UE) and a second bit stream for a second UE;
determining a time offset for the second UE based on a number of UEs operating in the TA-NOMA system and a pulse shape used in the TA-NOMA system; and
transmitting, on a resource allocated based on the time offset, a first signal corresponding to the first bit stream and a second signal corresponding to the second bit stream.
