Receiver-Specific Interventional Valuation of Semantic Atoms for Budget-Constrained Multi-Agent Communication
Danial Dehghani, Maximilian Lübke, Friedemann Laue +2
Cooperative multi-agent semantic communication requires deciding not only how a transmitter encodes its observation, but also which resulting semantic content should be delivered t…
Optimal Measurement Point Selection for Radio Environment Maps: A Two-Stage Approach
Bastian Perner, Friedemann Laue, Maximilian Lubke +1
Electromagnetic (EM) situational awareness is essential for the deployment and operation of local and temporary non-public networks (NPNs). Radio Environment Maps (REMs) provide an…
Convergence Time Distributions for Max-Consensus over Unreliable Networks
Katharina Stich, Bastian Perner, Friedemann Laue +2
This paper proposes the LiFE-CD algorithm for convergence time analysis of the max-consensus algorithm in multi-agent systems under Bernoulli-distributed link failures. Unlike exis…
Codebook-Based Self-Sustainable RIS: Optimal Splitting Schemes and Power Allocation
Friedemann Laue, Sebastian Lotter, Nikita Shani +1
This paper studies the codebook-based configuration of a reconfigurable intelligent surface (RIS) that extends the coverage of a base station (BS) while utilizing energy harvesting…
Performance Tradeoff Between Overhead and Achievable SNR in RIS Beam Training
Friedemann Laue, Vahid Jamali, Robert Schober
Efficient beam training is the key challenge in the codebook-based configuration of reconfigurable intelligent surfaces (RISs) because the beam training overhead can have a strong…
RIS Assisted Device Activity Detection with Statistical Channel State Information
Friedemann Laue, Vahid Jamali, Robert Schober
This paper studies reconfigurable intelligent surface (RIS) assisted device activity detection for grant-free (GF) uplink transmission in wireless communication networks. In partic…
IRS-Assisted Active Device Detection
Friedemann Laue, Vahid Jamali, Robert Schober
This paper studies intelligent reflecting surface (IRS) assisted active device detection. Since the locations of the devices are a priori unknown, optimal IRS beam alignment is not…
