“APROVECHAR LA TECNOLOGÍA PARA UN MEJOR MAÑANA” 13 - 15 de Noviembre 2013

Conferencia del DLT invitado por IEE COMSOC PERU – Ph. D. Ekram Hossain: 15 nov. 2013 “Redes inalámbricas celulares, cognitivas y de multinivel: Evolución hacia la 5G”

Resumen: La arquitectura de varios niveles con células pequeñas, como las femtoceldas , picocélulas ,

macrocélulas y metroceldas , superpuestas con las macrocéldas tradicionales se están desarrollando para

mejorar la cobertura y la capacidad de la próxima generación de redes inalámbricas celulares (4G, 5G y

posteriores). Además, en este tipo de redes de múltiples niveles , los conceptos de radiocomunicaciones

inteligentes serán utilizados por estas pequeñas células para mejorar la utilización del espectro

radioeléctrico. Sin embargo , el despliegue de pequeñas células en una arquitectura celular de varios niveles

plantean diversos retos, entre los cuales tenemos la gestión de recursos (es decir , gestión de interferencia,

control de potencia, control de admisión, balanceo de carga ) como el más importante. Esta conferencia

ofrecerá una visión general sobre el problema de la gestión de recursos de radio en redes de células

pequeñas 5G considerando células CDMA y OFDMA, y revisará el estado actual de este tema. Finalmente, se

indicarán los diversos retos a los cuales se encaminan y las direcciones futuras de investigación que se

pondrían orientar.

Title: Multi-tier and Cognitive Cellular Wireless Networks: Evolution Towards 5G

Abstract: Multi-tier architecture with small cells such as femtocells, picocells, microcells, and

metrocells, overlaid with traditional macrocells is being developed to improve the network coverage

and capacity of the next generation (beyond 4G and 5G) cellular wireless networks. Also, in such multi-

tier networks, cognitive radio concepts will be used by these small cells to improve the radio spectrum

utilization. However, deployment of small cells in a multi-tier cellular architecture poses many

challenges among which resource management (i.e., interference management, power control,

admission control, load balancing) is the most significant one. This lecture will provide an overview on

the radio resource management problem in 5G small cell networks considering both CDMA and OFDMA

small cells, and review the state-of-the-art research on this topic. To this end, several important open

research challenges and future research directions will be outlined.
