    Abstract : Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. READ MORE

  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.
