Device-to-device (D2D) communication is becoming a critical technology to improve the spectral efficiency in cellular communication systems. Although many upper-layer protocols have been designed for D2D communications, these work did not consider the specific characteristics of D2D channels, such as low antenna height and dual mobility, due to the lack of adequate D2D channel models. To promote research...
In this paper, we study and optimize the energy efficiency performance of heterogeneous network (HetNet) with the help of self-organized network (SON). Firstly, we propose a new and general power model for different types of base stations (BSs), where the impact of system load (including power load and bandwidth load), antenna port, carrier number, as well as the power supply and cooling system, is...
Energy efficiency has become one of the key performance indicators for 5G wireless networks. Coordinated multipoint (CoMP) transmission/reception and multiinput single-output (MISO) are two technologies which can achieve higher energy efficiency in heterogeneous networks (HetNets) compared to conventional single-input single-out (SISO) systems. CoMP improves energy efficiency by joint transmission...
