On the Capacity of the 2-User Gaussian MAC Interfering With a P2P Link
The Multiple Access Channel (MAC) is a scenario where several transmitters want to deliver one message each to one receiver. The capacity region of the MAC is known since 1971,. This setup models users that want to communicate with a base station in cell for example. The Interference Channel (IC) is another well studied model in information theory, that is a model where two transmit receive pairs want to communicate while causing interference to each other. The capacity of the IC is known in some cases.
