Query: Combining Schemes for Hybrid ARQ with Interference-Aware Successive
  Decoding   For decades, cellular networks have greatly evolved to support high data
rates over reliable communication. Hybrid automatic-repeat-request (ARQ) is one
of the techniques to make such improvement possible. However, this advancement
is reduced at the cell edge where interference is not negligible. In order to
overcome the challenge at the cell edge, the concept of interference-aware
receiver has been recently proposed in which both desired and interference
signals are successively decoded, called interference-aware successive decoding
(IASD). Although IASD is the advanced receiver technology, interference signals
are out of the mobile station's control so that they cannot be requested by the
mobile station. For this reason, this paper proposes new combining schemes for
the IASD receiver, which operate with hybrid ARQ in a bit level or in a symbol
level. In addition, this paper compares the memory requirement among the
proposed combining schemes and analyzes the impact of discrete modulation on
the proposed scheme. Simulation results presents the superiority of the
proposed combining schemes and shows the improvement in terms of the number of
transmission.
