1. An apparatus for wireless communication, comprising:
a processing system configured to:
map, at a first user equipment (UE), a first set of pilot symbols and a first set of data symbols to a plurality of tones, each pilot symbol in the first set of pilot symbols being mapped on a tone that is used by a second UE to carry a data symbol, at least one pilot symbol in the first set of pilot symbols overlapping in time on the tone that is used by the second UE to carry the data symbol; and
provide the mapped first set of pilot symbols and the mapped first set of data symbols for transmission over the plurality of tones, wherein the first set of pilot symbols are transmitted on tones shifted by a cyclic shift from a second set of pilot symbols that is concurrently transmitted by the second UE.
