摘要

本文提出了一种基于上行速率分割多址（RSMA-ALOHA）的槽ALOHA预配置信噪比（SINR）电平分配设计。然而，考虑到过载条件，RSMA-ALOHA的吞吐量由于碰撞而降低。其次，提出了自适应交通负荷（ATL）来管理过载交通状况和稳定吞吐量。ATL机制根据流量负荷估计动态控制RSMA-ALOHA的网络负荷。推导了吞吐量界限，证明了带有ATL的RSMA-ALOHA显著优于基准测试。仿真结果验证了理论分析的正确性，表明RSMA-ALOHA在各种交通条件下都能保持良好的吞吐量性能。

Uplink RSMA-Assisted Slotted ALOHA With Adaptive Traffic Load for Massive IoT

This letter presents a design of pre-configured signal-to-interference-plus-noise ratio (SINR) level allocation for slotted ALOHA assisted by uplink rate splitting multiple access (RSMA-ALOHA). However, considering the overload condition, the throughput of RSMA-ALOHA is degraded due to collisions. Next, adaptive traffic load (ATL) is proposed to manage overload traffic conditions and stabilize throughput. The ATL mechanism dynamically controls the network load of RSMA-ALOHA according to the traffic load estimation. The throughput bounds are derived, demonstrating that RSMA-ALOHA with ATL significantly outperforms the benchmark. Simulation results validate the theoretical analysis, showing that RSMA-ALOHA maintains superior throughput performance under varying traffic conditions.
