In future wireless
networks, a significant number of users accessing wireless broadband will be
vehicular (i.e., in public transportation vehicles like buses, trams, or
trains).
The Third Generation
Partnership Project has started to investigate how to serve these vehicular
users cost-effectively, and several solutions have been proposed. One promising
solution is to deploy a moving relay node (MRN), on a public transportation vehicle
that forms its own cell inside the vehicle to serve vehicular users. By proper antenna
placement, an MRN can reduce or even eliminate the vehicular penetration loss
that affects communication. Moreover, MRNs can exploit various smart antenna
techniques and advanced signal processing schemes, as they are less limited by
size and power than regular user equipment.
However, there are also
challenges in using MRNs, such as designing efficient interference management
techniques as well as proper mobility management schemes to exploit the benefit
of group handovers for vehicular UE devices served by the same MRN.
Nevertheless, initial system-level evaluation results indicate that a dedicated
MRN deployment shows great potential to improve the vehicular user experience, and
thereby can potentially bring significant benefits to future wireless
communication systems.
The article in
the presentation below gives further insights into this concept.
