  1. 1. Link Adaptation in 5G Networks : Reinforcement Learning Framework based Approach

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Siva Satya Sri Ganesh Seeram; [2022]
    Keywords : Link Adaptation; OLLA; AMC; Reinforcement Learning; DDPG; BLER; Länkanpassning; OLLA; AMC; förstärkningsinlärning; DDPG; BLER;

    Abstract : Link Adaptation is a core feature introduced in gNodeB (gNB) for Adaptive Modulation and Coding (AMC) scheme in new generation cellular networks. The main purpose of this is to correct the estimated Signal-to-Interference-plus-Noise ratio (SINR) at gNB and select the appropriate Modulation and Coding Scheme (MCS) so the User Equipment (UE) can decode the data successfully.

  3. 2. Reinforcement Learning for Link Adaptation in 5G-NR Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Evagoras Makridis; [2020]
    Keywords : ;

    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

  4. 3. Scheduling Algorithms and QoS in HSDPA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Javed Iqbal; Basit Mustafa; [2009]
    Keywords : HSDPA; QoS; Scheduling Algorithms;

    Abstract : High Speed Downlink Packet Access (HSDPA) is the extension to the Universal Mobile Telecommunication System (UMTS). HSDPA allows for higher data rates due to new adaptive Modulation and Coding (AMC) techniques, Hybrid Automatic Repeat reQuest (H-ARQ) and fast scheduling algorithm. READ MORE

  5. 4. HSDPA System Simulation

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Sohaib Khan; Nguyen Kim Cuong; [2005]
    Keywords : High Speed Downlink Packet Access HSDPA ; Adaptive Modulation and Coding AMC ; Packet Scheduling PS ; Hybrid Automatic Retransmit reQuest ARQ ; Node B; Radio Network Controller RNC ; High-speed Downlink Shared Channel HS-DSCH ; Transmission Time Interval TTI ; Link Adaptation;

    Abstract : This thesis provides a background of the high speed downlink packet access (HSDPA) concept; a new feature which has been introduced in the Release 5 specifications of the 3GPP WCDMA/UTRA-FDD standards. In order to emphasize the theoretical analysis, a simulation of a HSDPA system shall also be performed. .. READ MORE
