In this paper, we investigate a user-centric Coordinated Multiple Point (CoMP) transmission scheme to improve Energy Efficiency (EE) in dense Heterogeneous Network (HetNet), which takes advantage of both Dynamic Point Reduced Power (DPRP) and Joint Transmission (JT). DPRP with a user voting method rather than Dynamic Point Blanking (DPB) is introduced to fully use the power while reducing energy consumption...
To mitigate cross-tier interference, almost blank subframe (ABS) has been exploited for heterogeneous networks (HetNet). Macrocells mute or reduce transmission power to avoid interference to picocell edge users. However, the former results in unfairness between macrocells and picocells, and the latter fails to acquire a prominent improvement in energy efficiency (EE). In this paper, a time and frequency...
The energy consumption driven by dramatic growing demand for mobile data rates has attracted extensive attention. It is expected that the next generation cellular communication systems should improve not only spectral efficiency but also energy efficiency. Coordinated multi-point transmission (CoMP) and heterogeneous networks (HetNets) are two techniques for achieving high spectral efficiency and...
