Optimal age over erasure channels
WebApr 1, 2024 · In this paper, we study the problem of optimal joint scheduling of Type-I and Type-II UEs over wireless erasure channels. We characterize the freshness of information at a UE by a metric called the Age of Information (AoI) [ 12 ] , [ 13 ] . WebMay 24, 2024 · In this paper, we examine a status updating system where updates generated by the source are sent to the monitor through an erasure channel. We assume each update consists of k symbols and the symbol erasure in each time slot follows an independent and identically distributed (i.i.d.) Bernoulli process. We assume rateless coding scheme is …
