1. An apparatus for wireless communication at a base station, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
calculate a guard interval (GI) of each user equipment (UE) from a set of UEs based at least on a delay spread associated with each UE from the set of UEs;
multiplex data and the GI of each respective UE from the set of UEs to generate a waveform, wherein the data and the GI of each respective UE from the set of UEs are frequency domain multiplexed, wherein different GI configurations are used to frequency domain multiplex the data and the GI of each respective UE from the set of UEs, wherein the different GI configurations configure GIs having different lengths; and
transmit the waveform to the set of UEs.
