Abstract
Aspects described herein relate to modifying data for input to a discrete Fourier transform (DFT) so a set of resource elements (REs) output from the DFT for transmission in a communication direction includes one or more punctured REs corresponding to reference signals received in a different communication direction, performing the DFT for the data to generate the set of REs, mapping at least a portion of the set of REs to one or more symbols to generate a signal, and transmitting the signal in the communication direction. Other aspects relate to receiving the signal and decoding the data.
