UL e-ICIC Scheme Using SLP-ABS for Self-Organized Heterogeneous Cellular Networks

In this paper, an uplink (UL) enhanced intercell interference coordination (e-ICIC) scheme using synchronously configured low-power almost blank subframes is proposed for providing as efficient UL load balancing as in the downlink (DL) of a self-organized heterogeneous cellular network.

Description
Summary:In this paper, an uplink (UL) enhanced intercell interference coordination (e-ICIC) scheme using synchronously configured low-power almost blank subframes is proposed for providing as efficient UL load balancing as in the downlink (DL) of a self-organized heterogeneous cellular network. An analytical framework is provided as a theoretical background for a successful load balancing, and it is shown that the derived SIR distributions are quite close to the true ones in a wide range of network parameters so that it can be utilized for a successful load balancing. From the simulation results, it is shown that the proposed UL e-ICIC scheme can provide similar load balancing capability as the DL counterpart.
