The seminal inner bound for the IC using rate splitting. Still the best known achievable region after 40+ years.

Proves HK achieves within 1 bit of capacity for all Gaussian IC parameters. The ETW power split is a near-universal prescription.

Establishes the surprising result that the $K$-user IC has $K/2$ DoF via interference alignment. A landmark result in network information theory.

Proves TIN is sum-rate optimal in the noisy interference regime. Validates the 'ignore interference' approach.

Characterizes the full GDoF region with TIN and establishes conditions for TIN optimality.

The first result on the IC: capacity under very strong interference equals the interference-free capacity.

The interference channel capacity problem
A. El Gamal and Y.-H. Kim, Network Information Theory, Chapters 6 and 9
The most complete and rigorous treatment of IC inner and outer bounds, with detailed proofs. Essential for researchers working on the open capacity problem.
Interference alignment: theory and practice

Goes beyond the basic DoF result to cover feasibility conditions, the role of channel diversity, and why practical implementation is so challenging.
Practical interference management in cellular systems
Book telecom, Chapter 17 (MU-MIMO) and Chapter 20 (HetNets)
Covers the engineering side: how real systems manage interference through power control, scheduling, and MIMO processing without using IC capacity theory directly.
The K-user IC and beyond
R. Etkin, D. Tse, and H. Wang, 'Gaussian interference channel capacity to within one bit,' IEEE Trans. IT, 2008
The ETW paper contains not only the 1-bit result but also a masterful exposition of the different interference regimes and why HK is near-optimal.
