چکیده
To meet the increasing demands for passenger data rates, modern railway communication networks face significant challenges. The advent of 5G communications after long-term evolution (LTE) and LTE-Advanced (LTE-A) systems provides several technological advances to address these In this paper, reviewing main aspects railways, we describe seven challenges faced by train connectivity, discuss appropriate solutions. Specifically, elaborate on techniques ensuring connectivity energy efficiency passengers' user equipment (UE) through use mobile relays (MRs) top wagons in conjunction with intelligent resource allocation.
