As a profound and evident future trend in the field of mobile communication technologies development, heterogeneous networks became one of the crucial points of interests in wireless networks industry and academic research societies. Considering heterogeneous networks as an inseparable concept from LTE networks nowadays, which remain at position of advanced cellular system, the researchers aim to...
Time domain enhanced intercell interference coordination with Almost Blank Subframe (ABS) configuration for Macrocell is proposed in 3GPP to mitigate the inter-tier interference for heterogeneous networks (HetNets) consisting of Macrocells and overlaying Picos. The existing schemes for ABS power optimization are mainly base on the same level muted power of ABS, which will either cause time-frequency...
The femtocell deployment in 3GPP/LTE sets new challenges to interference mitigation techniques and Radio Resource Management (RRM). Traditional schemes are mainly designed for classical cellular networks while the ad hoc nature of femtocells notably limits the complexity of possible algorithms. Thus, efficient RRM schemes are essential for limiting the interference impact on end-user performance....
Femtocells are envisioned to be deployed in indoor environments in order to improve both radio coverage and system capacity. This paper focuses on the self-organization of enterprise femtocells, which is certainly more challenging than that of home femtocells. In the context of 3GPP LTE, we propose solutions to automatically tune parameters such as radio spectrum, pilot power, resource blocks, and...
