For single-antenna Gaussian interference channels, we re-formulate the problem of determining the Generalized Degrees of Freedom (GDoF) region achievable by treating interference as noise (TIN) with proper power control from a combinatorial optimization perspective. We show that the TIN power control problem can be cast into an assignment problem, such that the globally optimal power allocation variables can be obtained by well-known polynomial time algorithms. Furthermore, the expression of…

Optimality of Treating Interference as Noise: A Combinatorial Perspective

A low-complexity GDoF-based distributed link scheduling and power control mechanism (ITLinQ+) is proposed that improves upon the ITLinQ scheme proposed by Naderializadeh and Avestimehr and further improves over the heuristic approach known as FlashLinQ.

It is demonstrated that for K-user MIMO interference channels with different antenna numbers for transmitters and receivers, there exist non-trivial parameter regimes where a simple scheme of zero-forcing strong interference and treating the others as noise achieves the sum GDoF.

Provably near optimal link scheduling and power control for wireless device-to-device networks

This paper provides a link scheduling method that has the dual benefits of being based on the characteristics of real-life RF front-ends used in practical wireless networks and at the same time being analytically tractable and analyze its performance characteristics.

Secure GDoF of $K$-User Gaussian Interference Channels: When Secrecy Incurs No Penalty

This work shows that for TIN-optimal interference channels identified by Geng et al., secrecy constraints on unintended messages incur no GDoF penalty, which leads to a secure capacity region characterization within a constant gap.

Analytical Characterization of ITLinQ: Channel Allocation for Device-to-Device Communication Networks

An analytical characterization of ITLinQ is presented, one of the principal D2D channelization schemes proposed to date, and a stochastic geometry setting is utilized for this analysis, enabling gleaning insights on how IT LinQ avoids situations of excessive interference.

On the Optimality of Treating Interference as Noise

The generalized degrees of freedom region under this condition is a polyhedron, which is shown to be fully achieved by the same scheme, without the need for time-sharing, by first deriving a polyhedral relaxation of the GDoF region achieved by TIN and then providing a dual characterization of this polyhedral region via the use of potential functions.

On the Optimality of Treating Interference as Noise: Compound Interference Networks

This paper generalizes the optimality of TIN to compound networks and develops a centralized power control scheme for K-user compound interference channels that requires at most K updates to obtain the globally optimal power allocation for any feasible GDoF tuple.

On the Optimality of Treating Interference as Noise: General Message Sets

This paper shows that for such TINoptimal interference channels, even if the message set is expanded to include an independent message from each transmitter to each receiver, operating the new channel as the original interference channel and treating interference as noise is still optimal for the sum capacity up to a constant gap.

The explicit characterization of the sum capacity/sum GDoF of a TIN optimal network (without parallel channels) is interpreted as a minimum weighted matching problem in combinatorial optimization, and a simple characterization in terms of a partition of the interference network into vertex-disjoint cycles is obtained.

Topological Interference Management With Transmitter Cooperation

It is shown that the topological information can also be exploited in this case to strictly improve the degrees of freedom (DoF) as long as the network is not fully connected, which is a reasonable assumption in practice.

A New Outer Bound and the Noisy-Interference Sum–Rate Capacity for Gaussian Interference Channels

It is shown that if the channel crosstalk coefficient magnitudes lie below thresholds defined by the power constraints then single-user detection at each receiver is sum-rate optimal, i.e., treating the interference as noise incurs no loss in performance.
