1. A method of wireless communication, comprising:
determining that a beam change is to occur during a symbol;
receiving a time domain signal during at least a portion of the symbol, wherein the time domain signal includes a number of repetitions of a waveform;
performing a fast Fourier transform (FFT) on the time domain signal; and
determining transmitted bits or a channel from a subset of resource elements output from the FFT for a frequency domain allocation, wherein each resource element of the subset of resource elements is spaced apart by a number of empty resource elements equal to the number of repetitions of the waveform minus one.
