Impacto Del Reuso De Frecuencia Fraccional en La Reducción De Interferencia Intercelda en Lte.

Abstract: La Interferencia Inter-Celda (ICI, Inter-Cell Interference) es un problema que desafía el desempeño de las redes Evolución a Largo Término (LTE, Long Term Evolution), sin embargo existen técnicas de Coordinación de Interferencia Inter-Celda (ICIC, Inter-Cell Interference Coordination) como el Reuso de Frecuencia Fraccional (FFR, Fractional Frequency Reuse) que permiten mitigar dicha interferencia y mejorar el desempeño de los Equipos de Usuario (UE, User Equipment), especialmente aquellos terminales situados e… Show more

“…Two main interferences are present in LTE/LTE-A networks: intra-cell and inter-cell. The first one is produced between frequency channels within the same cell and thanks to OFDMA and its series of subcarriers (see Figure 1), its impact is low (Fernández et al, 2014). Alternatively, the ICI is produced between a frequency channel in a cell and the same channel used in an adjacent cell.…”

“…The amount of User Equipment [UE] within the large and dense mobile networks has suffered a considerable increase in the latest years (Fernández, González, & Hernández, 2014) due to the considerable data demand caused by the current requirements of the mobile services (Borkar & Pande, 2016). In order to support these bandwidth demands, standards such as the so-called Long-Term Evolution [LTE] and Long-Term Evolution -Advanced [LTE-A] are required to perform an adequate radio resource management (Kibria, Villardi, & Nguyen, 2016;Hu & Pang, 2012) and to improve their optimization functions.…”
