  1. 1. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Md Mamunur Rashid; [2023]
    Nyckelord :LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

    Sammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

    Sammanfattning : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. LÄS MER

  5. 4. Reconfigurable Intelligent Surfaces : Optimal Positioning and Coverage Improvement

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Noé Bernadas i Busquets; [2023]
    Nyckelord :6G; Reconfigurable Intelligent Surfaces; Wireless Communications; Coverage; 6G; omkonfigurerbara intelligenta ytor; trådlös kommunikation; täckning;

    Sammanfattning : Med framväxten av framtida mobilgenerationer bortom 5G, studeras nya teknologier för att tillgodose de förväntade kraven för framtida tjänster som Ultra-Reliable Low Latency Communications (URLLC) eller Virtual Reality. Bland dessa teknologier uppstår Reconfigurable Intelligent Surfaces (RIS) som en av de mest lovande på grund av deras förmåga att förbättra kanalen samtidigt som de bara ökar nätverkets energiförbrukning måttligt.

  7. 5. Mobile Traffic Classification and Multi-Cell Base Station Control for Energy-Efficient 5G Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Cai Tianzhang; [2023]
    Nyckelord :;

    Sammanfattning : The global energy consumption of mobile networks is rapidly increasing due to the exponential growth of mobile network traffic. The advent of next-generation cellular technologies such as fifth-generation (5G) and beyond promises higher network throughput and lower latency but also demands higher power consumption for its denser base station (BS) deployment and more energy-intensive processors.
