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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
