Abstract :
This paper introduces the potential of downlink interference cancellation (IC) receivers in LTE user equipments, where the interfering signal is channel decoded by the victim receiver. After an introduction to possible IC schemes, we discuss the challenges related to making IC feasible, and the related changes required in the LTE standard. Preliminary system-level simulation results for both full buffer and non full buffer traffic models show that IC has a great potential for capacity and user experience gains. These results are based on an idealistic modelling of IC, therefore providing an upper bound of the gains achievable in practice.
