Minimum-Latency Scheduling For Partial-Information Multiple Access Schemes
Alberto Rech, Stefano Tomasin, Lorenzo Vangelista +1
Partial-information multiple access (PIMA) is an orthogonal multiple access (OMA) uplink scheme where time is divided into frames, each composed of two parts. The first part is use…
Semi-Grant-Free Orthogonal Multiple Access with Partial-Information for Short Packet Transmissions
Alberto Rech, Stefano Tomasin, Lorenzo Vangelista +1
Next-generation internet-of-things (IoT) networks require extremely low latency, complexity, and collision probability. We introduce the novel partial-information multiple access (…
Downlink Clustering-Based Scheduling of IRS-Assisted Communications With Reconfiguration Constraints
Alberto Rech, Matteo Pagin, Leonardo Badia +4
Intelligent reflecting surfaces (IRSs) are being widely investigated as a potential low-cost and energy-efficient alternative to active relays for improving coverage in next-genera…
Unsourced Random Access With Tensor-Based and Coherent Modulations
Alberto Rech, Alexis Decurninge, Luis G. Ordóñez
Unsourced random access (URA) is a particular form of grant-free uncoordinated random access wherein the users' identities are not associated to specific waveforms at the physical…
Partial-Information Multiple Access Protocol for Orthogonal Transmissions
Alberto Rech, Stefano Tomasin, Lorenzo Vangelista +1
With the stringent requirements introduced by the new sixth-generation (6G) internet-of-things (IoT) use cases, traditional approaches to multiple access control have started to sh…
Downlink TDMA Scheduling for IRS-aided Communications with Block-Static Constraints
Alberto Rech, Matteo Pagin, Stefano Tomasin +5
Intelligent reflecting surfaces (IRSs) are being studied as possible low-cost energy-efficient alternatives to active relays, with the goal of solving the coverage issues of millim…
