Long Term Evolution (LTE) is 3GPP enhancement to the current cellular system in use. The purpose of developing this system is to keep 3GPP systems competent enough for decades to come. LTE is designed to have wider channels up to 20MHz, with low latency and packet optimized radio access technology. The peak data rate envisaged for LTE is 100 Mbps in(More)
Self-organizing networks (SONs) can carry out their optimization procedures in an on- or off-line manner. On one hand, an online SON solution optimizes network parameters during operation. On the other hand, an offline SON solution employs a simulation environment of the network to be optimized in order to perform an offline parameter optimization before(More)
The deployment of low-power small cells is envisaged as the main driver to accommodate the mobile broadband traffic growth in cellular networks. Depending on the spatial distribution of the user traffic, a densification of the small cells may be required in confined areas. However, deploying more and more cells in given areas may imply an increase of the(More)
Networks beyond 2020 will experience 10000-fold increase in wireless traffic, connect 10-100 times more devices and support the most diverse use cases. Thus, the 5G architecture needs to be flexible and cater for both traffic volumes and diversity of service requirements. Among the set of new use cases, support of delay sensitive "mobile" applications, such(More)
This paper presents an analytical approach to HSDPA radio interface dimensioning based on specific requirements for throughput and exploited downlink transmission power. The proposed method derives the maximum HSDPA throughput achievable in a cell with the actual radio resources, or the power needed for HSDPA to provide the required average or minimum user(More)
Coverage extension and quality, cell power utilization, neighbor cells ranking and other information normally provided by expensive field measurement campaigns can alternatively be extracted from signaling monitored in the Radio Network Controller. This paper, after reviewing a set of key performance metrics and optimization solutions validated(More)
Self-organizing networks (SONs) are widely considered as a major facilitator in improving the end users' quality of experience. Developing well-performing and reliable algorithms is still an ongoing research topic. A majority of contributions propose SON algorithms that optimize a desired metric by the use of detailed input data, such as maps of received(More)
This paper presents a method to detect coverage and dominance problems and identify interferers in WCDMA networks. The solution does not make use of drive tests or simulations. For each cell and cell pair, metrics are calculated processing signalling messages exchanged through the radio interface during normal network operation, thus reflecting real traffic(More)
In the field of self-organizing networks (SONs), the use case of concurrent capacity and coverage optimization (CCO) is challenging since the objectives are typically conflicting and adequate solutions often require interaction between a multitude of network sites. As a consequence, solving the use case of CCO is particularly difficult. This letter proposes(More)
