In this thesis, an Overview of the LTE Downlink Scheduling Algorithms is presented. LTE provides high data rates and is expected to be used by many users in future since it has good coverage and has access to internet through their devices. The main mechanism of this LTE network in handling the user traffic is the scheduler. A scheduler is a key functionality in which the base-station decides which user should be given resources to receive or send the information. We focused on LTE Downlink schedulers and their functionality by studying their algorithms. The users are assigned with the shared resources by the network scheduler. We considered two scheduling algorithms, Round Robin and the Best CQI. The impact of each scheduler in terms of throughput and fairness and their abilities are known. Throughput and fairness are the two performance measures in the scheduler. By studying these two schedulers, a new scheduler is proposed which is a compromise between the throughput and the fairness.
