1. An apparatus for wireless communication, comprising:
memory; and
at least one processor coupled to the memory, the at least one processor configured to:
receive a first symbol of a single carrier waveform, the first symbol including a first set of demodulation reference signal (DMRS) resources;
receive a second symbol of the single carrier waveform, the second symbol including a second set of DMRS resources, the second set of DMRS resources associated with at least one of a DMRS starting location and a DMRS duration that is different than the first set of DMRS resources; and
estimate a channel condition based on at least one of the first set of DMRS resources and the second set of DMRS resources.
