Adaptive Interference Coordination over Channels with Unknown State at the Encoder and the Decoder

TL;DR

This paper extends interference coordination over channels with unknown states at both ends, providing a complete characterization of the capacity region for a compound DMC with state-dependent interference constraints.

Contribution

It introduces a generalized model for interference control over compound channels with unknown states and derives the full capacity region for this scenario.

Findings

Capacity region characterized for the compound DMC with unknown state.

Interference coordination levels depend on channel state.

Generalization of previous interference control models.

Abstract

We generalize the problem of controlling the interference created to an external observer while communicating over a discrete memoryless channel (DMC) which was studied in \cite{serrano:2014}. In particular, we consider the scenario where the transmission is established over a compound DMC channel with unknown state at both the encoder and the decoder. Depending on the exact state $s$ of the channel, we ask for a different level of average precision $\Delta_s$ on the establishment of the interference coordination with the external observer. For this set-up, we fully characterize the capacity region.
