Abstract

Four outer bounds are given for the weak and mixed interference cases, all derived from existing outer bounds for the classic interference channel: a) Carleial's outer bound, b) Kramer's genie aided approach that gives both receivers enough information to decode all the messages, c) Kramer's Z-channel based outer bound, d) a recent outer bound proposed in [1]. We show that b) unified and improves a) and the existing outer bound by Tan (1980); c) further improves upon b); c) and d) do not have a subset relation.
