Abstract

Long-term evolution (LTE) architecture has recently been enhanced by means of the introduction of multi-antenna systems that make use of multiple input multiple output (MIMO) technology, both at the base transceiver station (eNodeB) and user equipment (UE). MIMO can deploy transmission diversity to achieve more robust transmission in poor propagation conditions and spatial multiplexing to increase throughput and thus LTE performance from an end-user perspective. The most recent version of the standard (Release 10) makes up to eight antennae available for the downlink transmission channel. The paper focuses on the most relevant physical-layer parameters used by LTE to optimise a MIMO system. Performance at different frequencies and bandwidths is investigated over a wide urban area in order to study the network behaviour in actual propagation conditions and to verify whether standard prescriptions are satisfied by a fully operational LTE mobile communication system.

Author Biography

Stefania Zinno, Università degli Studi di Napoli Federico II, Naples, Italy

Stefania Zinno received her PhD in 2018 from the University of Naples Federico II, Naples Italy in Information Technology and Electrical Engineering (ITEE).

She also holds a Master, SIRIO-FORM Servizi per l'Infrastruttura di  Rete wIreless Oltre il 3G, from CNIT and MIUR.

Research fields of interest are related to LTE-Advanced, physical and MAC layer. This represents a wide issue, which spans from the scheduling and AMC procedure, Handover and load balancing and also Carrier Aggregation both in Unlicensed and Licensed  Bandwidth.

Recent research activity has been mostly focused on the study of Innovative way of assessing physical layer parameters of LTE Networks in order to determine proper optimisation algorithms with a view to greater effectiveness and efficient network management
