Chapter 16

Heterogeneous Deployments

Abstract

This chapter discusses deployments consisting of multiple cell layers, including so-called heterogeneous network deployments, the specific interference situations that can occur in such deployments, and the means by which these can be handled within LTE.

Keywords

heterogeneous deployments; enhanced inter-cell interference coordination (eICIC); shared cell

The continuous increase in traffic within mobile-broadband systems and an equally continuous increase in terms of the data rates requested by end-users will impact how cellular networks are deployed in the future. In general, providing very high system capacity (traffic per area unit) and very high per-user data rates will require a densification of ...
