Resource management in LTE (Long Term Evolution).

LTE introduces a new challenge in the resource management due to the special characteristics of OFDM (Orthogonal Frequency Division Multiplexing). In OFDM frequency and time slots are dinamically assigned to each user employing a certain modulation and coding scheme. ToT researchs on innovative solutions to interference coordination between base stations and algorithmics that fully exploit MIMO (Multiple-input Multiple-output) techniques.

This project is cofinanced as a AVANZA I+D subprogramme by the Spanish Ministry of Industry, Commerce and Tourism (MITYC) with expedient number: TSI-020100-2010-240


Indoor coverage analysis in LTE.

ToT has developed a tool for the LTE deployment optimization, focused on the maximization of capacity and user experience (QoS) inside buildings.

This project, known as EVOSIS, was cofinanced by the Spanish Ministry of Industry, Energy and Tourism (MITYC), as part of the National Plan for Scientific Research, Development and Technological Innovation 2013-2016, with expedient number: TSI-100102-2013-35


User speed estimation in heterogeneous networks.

This project, known as "EVEREST - Estimación de la velocidad del móvil en redes heterogéneas", is cofinanced by the Spanish Ministry of Industry, Energy and Tourism, as part of the National Plan for Scientific Research, Development and Technological Innovation 2013-2016, with expedient number: TSI-100102-2014-72


VOIP over HSxPA.

Real-time services have tigth requirements of quality of service and delay in the communication channel. ToT researchs on the configuration and parameters needed to offer a real-time service such as VoIP over HSxPA channels.

This project is cofinanced as a AVANZA I+D subprogramme by the Spanish Ministry of Industry, Commerce and Tourism (MITYC) with expedient number: TSI-020100-2009-100
