1. An apparatus for wireless communication, comprising:
- a processing system configured to;
receive a plurality of combined signals, each combined signal being on a tone of a plurality of tones, each combined signal comprising a first symbol of a first plurality of symbols from a first user equipment (UE) and a second symbol of a second plurality of symbols from a second UE, the first plurality of symbols including at least one first pilot symbol and at least one first data symbol, the second plurality of symbols including at least one second pilot symbol and at least one second data symbol, each of the at least one first pilot symbol being on a tone that carries one of the at least one second data symbol;
determine a first pilot signal on a first tone of the plurality of tones, the first tone carrying a respective one of the at least one first pilot symbol and a respective one of the at least one second data symbol, the first pilot signal being determined based on a channel element associated with the first tone and the respective one of the at least one first pilot symbol on the first tone; and
generate an interference-reduced signal for the first tone by canceling the determined first pilot signal from the first tone of the plurality of tones;
de-interleave the plurality of combined signals to determine a first set of pilot signals from the first UE, first and second code blocks from the first UE, a second set of pilot signals from the second UE, and third and fourth code blocks from the second UE; and
perform successive decoding of code blocks after de-interleaving the plurality of combined signals by;
decoding the third code block by canceling the first set of pilot signals from the third code block;
decoding the first code block by canceling the third code block from the first code block;
decoding the fourth code block by canceling the first code block from the fourth code block; and
decoding the second code block by canceling the fourth code block from the second code block.

Abstract
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to receive a plurality of combined signals. Each combined signal may be on a tone of a plurality of tones. The apparatus may be configured to determine a first pilot signal on a first tone of the plurality of tones. The apparatus may be configured to generate an interference-reduced signal for the first tone by canceling the determined first pilot signal from a first combined signal on the first tone.
