TLDR
The capacity region of a Gaussian interference channel with two separate messages is obtained for the case of moderately strong interference and it is shown that the region coincides with the one where both messages are required in both receiving terminals.Abstract:

Rate-splitting and successive decoding for Gaussian interference channels
Ali Haghi,Amir K. Khandani +1 more
TL;DR: This paper studies the achievable sum-rate of the two-user Gaussian interference channel when joint decoding is replaced by successive decoding, and it is proved that the difference between the sum- rate of this scheme and that of the Han-Kobayashi scheme is bounded, even when transmitters' powers approach infinity.

On the sum secure degrees of freedom of two-unicast layered wireless networks
Jianwei Xie,Sennur Ulukus +1 more
TL;DR: This paper considers the setting where the message of each source-destination pair must be kept information-theoretically secure from the unintended receiver, and shows that the sum secure d.o.f. can take 0, 1, 3/2, 2 and at most countably many other positive values, which are enumerate.

Quantum interference channels
TL;DR: In this article, the authors studied the quantum interference channel, a generalization of a two-input, two-output memoryless channel to the setting of quantum Shannon theory, and discussed three different coding strategies and obtained corresponding achievable rate regions.

Interference MAC: Impact of improper Gaussian signaling on the rate region Pareto boundary
TL;DR: This paper uses improper Gaussian signaling (instead of proper) at the transmitters to increase the design flexibility, which offers the freedom of optimizing the transmit signal pseudo-variance in addition to its variance, and formulate the weighted max-min problem as a semidefinite program, and use semideFinite relaxation (SDR) to obtain a near-optimal solution.

A case where interference does not reduce capacity (Corresp.)
TL;DR: In this paper, it was shown that under certain conditions, two strongly interfering communication links with additive white Gaussian noise can achieve rates as high as would be achievable without this interference.

The Capacity Region of a Channel with Two Senders and Two Receivers
TL;DR: In this paper, a characterization of the capacity region of a two-way channel is given for the communication situation, in which both senders send independent messages simultaneously to both receivers and all senders and receivers are at different terminals.

Two-user communication channels
TL;DR: Degraded two-user channels are introduced and studied in detail; in particular, an achievable region is obtained by combining two regions that correspond to the two different modes of transmission.
