1. Efficient Transmission over Unknown Channels
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : In recent years, digital transmission techniques have been continuously evolving by employing increasingly more advanced Modulation and Coding Scheme (MCS). However, when the wireless channel is varying rapidly, it is hard or even impossible for the transmitter to select the proper MCS. READ MORE

2. Reinforcement Learning for Link Adaptation in 5G-NR Networks
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The Adaptive Modulation and Coding (AMC) scheme in the link adaptation is a core feature in the current cellular networks. In particular, based on Channel Quality Indicator (CQI) measurements that are computed from the Signal-to-Interference-plus-Noise Ratio (SINR) level of User Equipment (UE), the base station (e.g. READ MORE
