  1. 1. Radio resource management for wireless indoor communication systems : performance and implementation aspects

    Författare :Stefan Pettersson; KTH; []
    Nyckelord :Radio resource management; indoor communication; the bunch concept; centralized RRM; dynamic channel allocation; channel selection;

    Sammanfattning : In this thesis, we investigate several radio resourcemanagement (RRM) techniques and concepts in an indoorenvironment with a dense infrastructure. Future wireless indoorcommunication networks will very likely be implemented atplaces where the user concentration is very high. At these hotspots, the radio resources must be used efficiently.

  3. 2. Radio Resource Management in Bunched Personal Communication Systems

    Författare :Miguel Berg; KTH; []
    Nyckelord :radio resource management; dynamic channel allocation; power control; interference avoidance; link-gain matrix; path-loss measurements; microcells; mobile positioning; trilateration;

    Sammanfattning : The traditional way of increasing capacity in a wirelesscommunication system has been cell splitting and fixedchannel-allocation based on prediction tools. However, theplanning complexity increases rapidly with the number of cellsand the method is not suitable for the large temporal andspatial traffic variations expected in the future. LÄS MER

  4. 3. Serving IoT Communications over Cellular Networks : Challenges and Solutions in Radio Resource Management for Massive and Critical IoT Communications

    Författare :Amin Azari; Jens Zander; Cicek Cavdar; Guowang Miao; Merouane Debbah; KTH; []
    Nyckelord :5G; Battery lifetime; Grant-based and grant-free access; Massive and critical IoT communications; Radio resource manage; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Internet of Things (IoT) communications refer to the interconnections of smart devices, with reduced human intervention, which enable them to participate more actively in everyday life. It is expected that introduction of a scalable, energy efficient, and reliable IoT connectivity solution can bring enormous benefits to the society, especially in healthcare, wellbeing, and smart homes and industries.

    Sammanfattning : Safety applications play an essential role in supporting traffic safety and efficiency in next generation vehicular networks. Typical safety applications require vehicle-to-vehicle (V2V) communication with high reliability and low latency. LÄS MER

  7. 5. Demand responsive resource management for cellular networks : link asymmetry, pricing and multihopping

    Författare :Magnus Lindström; Jens Zander; Narayan Mandayam; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : Economic affordability of services and infrastructures has rapidly become one of the key issues in the evaluation and design of wireless access systems. The provisioning of high data rates, at an ``affordable'' price, constitutes a serious challenge to the structure and management of current and future wireless networks. LÄS MER
