This paper aims at characterizing the energy efficiency (EE)—area spectral efficiency (ASE) tradeoff in random geometry networks with multiple-antenna arrays at base stations (BSs). In particular, ASE and EE are studied with respect to the transmit power when BSs use a signal-to-leakage-plus-noise ratio (SLNR) precoder. When the static power consumption cannot be neglected, EE behaves linearly with...
Signal-to-leakage-and-noise ratio (SLNR) is a promising criterion for linear precoder design in multiuser multiple-input multiple-output systems. In this paper, an expression of a precoder maximizing SLNR based on the generalized Rayleigh quotient theorem is derived for cellular networks. Compared with the conventional SLNR precoders, we consider the non-homogeneous average received signal-to-noise...
This paper deals with the energy-efficiency spectral-efficiency (EE-SE) tradeoff in regular hexagonal interference-limited networks. We aim to characterize the EE-SE region when non negligible static circuitry power consumption is assumed and when several frequency reuse factors as well as shadowing are taken into account. Our contribution is three-fold: i) a parametric expression of the interference...
