A Nonlinear Autoregressive Neural Network for Interference Prediction and Resource Allocation in URLLC Scenarios
Christian Padilla, Ramin Hashemi, Nurul Huda Mahmood +1
Ultra reliable low latency communications (URLLC) is a new service class introduced in 5G which is characterized by strict reliability and low latency requirements (1…
Deep Reinforcement Learning for Practical Phase Shift Optimization in RIS-aided MISO URLLC Systems
Ramin Hashemi, Samad Ali, Nurul Huda Mahmood +1
We study the joint active/passive beamforming and channel blocklength (CBL) allocation in a non-ideal reconfigurable intelligent surface (RIS)-aided ultra-reliable and low-latency…
Average Rate Analysis of RIS-aided Short Packet Communication in URLLC Systems
Ramin Hashemi, Samad Ali, Nurul Huda Mahmood +1
In this paper, the average achievable rate of a re-configurable intelligent surface (RIS) aided factory automation is investigated in finite blocklength (FBL) regime. First, the co…
Average Rate and Error Probability Analysis in Short Packet Communications over RIS-aided URLLC Systems
Ramin Hashemi, Samad Ali, Nurul Huda Mahmood +1
In this paper, the average achievable rate and error probability of a reconfigurable intelligent surface (RIS) aided systems is investigated for the finite blocklength (FBL) regime…
Energy Efficiency Maximization in the Uplink Delta-OMA Networks
Ramin Hashemi, Hamzeh Beyranvand, Mohammad Robat Mili +3
Delta-orthogonal multiple access (D-OMA) has been recently investigated as a potential technique to enhance the spectral efficiency in the sixth-generation (6G) networks. D-OMA ena…
