A new upper bound for the sum-capacity of the two-user complex Gaussian interference channel is derived. The bound is based on genies that provide side information signals to the receivers. Various parameters are introduced to control the side information, which can be optimized to get the tightest possible bound. The new bound improves the performance of the best known bounds for sufficiently small cross-gains.
