How Scheduler Design in LTE?

•Most scheduling strategies need information about:
–Channel condition
–Buffer status and priorities of the different data flows
–Interference situation in neighboring cells


Remember few major things while designing:
•Throughput
•Efficiency
•QoS Support
–Different types and levels of QoS, respective for different service applications
–Attributes such as bandwidth, delays, error rate and jitter
–Need to serve each subscriber at a certain minimum QoS based on his/her Service Level Agreement (SLA)
•Fairness
–Is a measure of customer satisfaction.
–Neglecting subscribers unfairly in order to increase throughput may lead to high churn rates
