Topic:

Robust Uplink Communication with Variable Backhaul Connectivity

Abstract - This study focuses on systems in the context of robust distributed cell processing, and is motivated by recent concepts of cloud radio access networks. We consider a simple system (cellular for example) where:

  • Two mobile users communicate with a central (cloud) decoder via two base stations;
  • The mobile users are connected to the base stations by a Gaussian channel with quasi-static fading;
  • The base stations are connected to the decoder by orthogonal finite-capacity links, whose connectivity is subject to random fluctuations;
  • The mobile users are unaware of the channel state or of the backhaul connectivity state;
  • The base stations are uncertain about the state of the backhaul links;
  • The base stations are oblivious to the mobile users' codebooks and employ a robust compress-and-forward procedure to relay information to the central decoder.

We derive upper and lower bounds on the average achievable throughput with respect to the prior distribution of the fading coefficients and of the states of the backhaul links. Whether with or without fading, the analysis and numerical results reveal the importance of broadcast coding and layered compression in opportunistically leveraging advantageous channel and backhaul conditions.

This is joint work with R. Karasik (Technion) and O. Simeone (NJIT).
