  3. 2. WCDMA Cell Load Control in a High-speed Train Scenario : Development of Proactive Load Control Strategies

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Raoul Joshi; Per Sundström; [2012]
    Keywords : WCDMA; High-speed Train; Congestion Control; Admission Control; Load Control; Cell Capacity; Cell Resource Allocation; Train Detection; Quality of Service; Dropping Fairness; Predictive Load Control;

    Abstract : Load control design is one of the major cornerstones of radio resource management in today's UMTS networks. A WCDMA cell's ability to utilize available spectrum efficiently, maintain system stability and deliver minimum quality of service (QoS) requirements to in-cell users builds on the algorithms employed to manage the load.

  6. 5. Interference Management in LTE-Advanced Heterogeneous Networks Using Almost Blank Subframes

    University essay from KTH/Signalbehandling

    Author : Hisham El-Shaer; [2012]
    Keywords : ;

    Abstract : Long term evolution (LTE) is the standard that the Third-generation Partnership Project (3GPP) developed to be an evolution of UMTS. LTE offers higher throughput and lower latency than UMTS and this is mainly due to the larger spectrum used in LTE but in terms of spectrum efficiency LTE does not offer a lot of improvements compared to UMTS.
