title = "The capacity of the interference channel with a cognitive relay in strong interference",
abstract = "The interference channel with a cognitive relay consists of a classical interference channel with two source-destination pairs and with an additional cognitive relay that has a priori knowledge of the sources' messages and aids in the sources' transmission. We derive a new outer bound for this channel using an argument originally devised for the {"}more capable{"} broadcast channel, and show the achievability of the proposed outer bound for a class of channels where there is no loss in optimality if both destinations decode both messages. This result is analogous to the {"}very strong interference{"} capacity result for the classical interference channel and for the cognitive interference channel, and is the first capacity known capacity result for the general interference channel with a cognitive relay.",
