The blooming of internet things (IoT) services calls for a paradigm shift in the design communications systems. Short data packets sporadically transmitted by multitude low-cost low-power terminals require radical change relevant aspects protocol stack. For example, scheduling-based approaches may become inefficient at medium access (MAC) layer, and alternatives such as uncoordinated policies be preferred. In this context random (RA) its simplest form, i.e., additive links on-line Hawaii...
Global System for Mobile communication - Railway (GSM-R) is widely used operational communications between train and signaler. However, there a need to define successor that addresses: obsolescence, radio spectrum demand the enabling of range emerging digital applications such as radio-based signaling Automatic Train Control (ATC). Therefore, International Union Railways (UIC) started initiative develop Future Communication (FRMCS). This article describes an Adaptable (ACS) being developed...
A vast population of low-cost low-power transmitters sporadically sending small amounts data over a common wireless medium is one the main scenarios for Internet things (IoT) communications. At access, use grant-free solutions may be preferred to reduce overhead even at cost multiple-access interference. Unsourced multiple access (UMA) has been recently established as relevant framework energy efficient protocols. The compressed sensing (CS) transmission phase key in two classes UMA...
