摘要：

The main aim of this paper is to analyze the effects of periodic and aperiodic CQI Feedback (Channel Quality Indicator) on the QoS (Quality of Service) for LTE (Long Term Evolution) networks, using the simulator ns-3. We analyze how the QoS parameters change when more devices are aggregated to the base station and the scheduler allocates optimal radio resources for each user. In this scenario, the QoS depends on the type of CQI Feedback configured to estimate the quality of channel. The QoS can be modified according to the QCI, that identifies each transmission per TTI (Transmit Time Interval).
