In an example implementation, the method may include configuring, by a gNB, a first numerology parameter that enables at least symbol repetition and a modified cyclic prefix, and transmitting, by the gNB, a downlink signal/channel that is configured based at least on the symbol repetition and modified cyclic prefix. In another example implementation, the method may include configuring, by a user equipment (UE), a first numerology parameter that enables at least symbol repetition and modified cyclic prefix based at least on information received from a gNB, aligning, by the UE, fast Fourier transform (FFT) windows with boundaries of the repeated symbols, and processing, by the UE, a downlink signal/channel received from the gNB based at least on the aligning.
