On the Age-Optimality of Relax-then-Truncate Approach under Partial Battery Knowledge in Energy Harvesting IoT Networks
Mohammad Hatami, Markus Leinonen, Marian Codreanu
We consider an energy harvesting (EH) IoT network, where users make on-demand requests to a cache-enabled edge node to send status updates about various random processes, each moni…
Joint Estimation of Clustered User Activity and Correlated Channels with Unknown Covariance in mMTC
Hamza Djelouat, Markus Leinonen, Markku Juntti
This paper considers joint user identification and channel estimation (JUICE) in grant-free access with a \emph{clustered} user activity pattern. In particular, we address the JUIC…
Joint Coherent and Non-Coherent Detection and Decoding Techniques for Heterogeneous Networks
Leatile Marata, Onel Luis Alcaraz López, Hamza Djelouat +3
Cellular networks that are traditionally designed for human-type communication (HTC) have the potential to provide cost effective connectivity to machine-type communication (MTC).…
Query-Age-Optimal Scheduling under Sampling and Transmission Constraints
Abolfazl Zakeri, Mohammad Moltafet, Markus Leinonen +1
This letter provides query-age-optimal joint sampling and transmission scheduling policies for a heterogeneous status update system, consisting of a stochastic arrival and a genera…
Status Update Control and Analysis under Two-Way Delay
Mohammad Moltafet, Markus Leinonen, Marian Codreanu +1
We study status updating under two-way delay in a system consisting of a sampler, a sink, and a controller residing at the sink. The controller controls the sampling process by sen…
Multi-Source AoI-Constrained Resource Minimization under HARQ: Heterogeneous Sampling Processes
Saeid Sadeghi Vilni, Mohammad Moltafet, Markus Leinonen +1
We consider a multi-source hybrid automatic repeat request (HARQ) based system, where a transmitter sends status update packets of random arrival (i.e., uncontrollable sampling) an…
