Reinforcement Learning for Link Adaptation in 5G-NR Networks

NettetA Novel Machine Learning Approach for Link Adaptation in 5G Wireless Networks Abstract: This study addresses a Machine Learning (ML) based Link Adaptation (LA) … NettetA. Link Adaptation The purpose of the link adaptation is to enable a reliable data rate and throughput in the radio link adapting the trans-mission parameters at gNB side [11]. LA schemes consists mainly on the so-called inner loop link adaptation (ILLA) and outer loop link adaptation (OLLA). The ILLA scheme is pulseira johnny depp

DELUXE: A DL-Based Link Adaptation for URLLC/eMBB Multiplexing in 5G …

Nettetperform rate adaptation. SINR is used for rate anchoring called inner look adaptation and ACK/NACK is used for fine offset adjustments called Outer Loop Link Adaptation (OLLA). We cast the OLLA as a reinforcement learning problem of the class of Multi-Armed Bandits (MAB) where the different offset values are the arms of the bandit. NettetA self-optimization algorithm was proposed in [19] for outer loop link adaptation of LTE downlink channel. Based on recordings of connection traces, their algorithm adapts the initial OLLA offset ... NettetLink adaptation—the dynamic selection of data rate based on estimates/predictions of the instantaneous channel conditions to be experienced by a transmission—is one of the basic mechanisms for good system performance in LTE. pulseira louis vuitton masculina couro
