Abstract

Centralized architectures with fronthauls can be used to deal with some of the problems inherently associated with dense small cell deployments. This study examines a joint cell assignment and scheduling solution for the downlink to increase the users’ data rates, based on cell switching and a suboptimal optimization algorithm that nearly achieves the performance of the optimal Hungarian assignment. Moreover, an exhaustive sensitivity analysis with different network and traffic configurations is carried out in order to understand what conditions are more appropriate for the use of the proposed mechanism and solutions involving cell switching in general. Simulation results
show that such solutions can greatly benefit from the use of receivers with interference suppression capabilities and a larger number of antennas, with a maximum data rate gain of 120%. High performance gains are observed with two different traffic models, and it is not necessary to be able to connect to a large number of cells in order to reap most of the benefits of the centralized dynamic cell selection.
