Sixth-generation (6G) mobile communication networks are expected to have dense
infrastructures, large antenna size, wide bandwidth, cost-effective hardware, diversified …

Cellular networks have been undergoing an extraordinarily fast evolution in the past years.
With commercial deployments of Release 8 (Rel-8) Long Term Evolution (LTE) already …

In this paper, we analyze vertical handovers in heterogeneous networks. Vertical handovers
are an important ramification of user mobility in a heterogeneous wireless network since …

In this paper, we address the problem of reconstructing coverage maps from path-loss
measurements in cellular networks. We propose and evaluate two kernel-based adaptive …

Hybrid automatic repeat request (HARQ) is widely used in heterogeneous cellular networks
(HCNs) to improve communication reliability. The temporal interference correlation caused …

In 5G HetNets, the massive deployments of small cells result in an excessive number of
handovers, including both vertical and horizontal handovers, which induces heavy …

The integration of Internet of Things (IoT) and heterogeneous cellular networks (HCNs)
forms a promising paradigm for next generation mobile systems. In this paper, a new …

Radio maps can provide insightful information about the wireless environment to improve
flexibility and intelligence of wireless networks. Channel gain cartography aims at …

Accurate coverage maps are an important tool for network planning and operation but it is
often impossible to obtain these maps completely from measurements. In this paper we …

Learning any-to-any (A2A) path loss maps, where the objective is the reconstruction of path
loss between any two given points in a map, might be a key enabler for many applications …
