MIMO Link Adaptation with Carrier Aggregation in LTE-A Heterogeneous Networks

Page

Abstract

In this work, we present an enhanced MIMO LA algorithm, which facilitates the improvement of the total throughput when CA is employed in HetNets. In particular, the performance of the LTE-A physical downlink channel is assessed in terms of throughput, assuming that the proposed algorithm is utilized in a closed-loop spatial multiplexing MIMO wireless system under non-continuous heterogeneous CA.
