Research and Realization on Wireless Packet Scheduling Algorithm and Resource Allocation Strategy in TD-LTE Downlink System

In the LTE system, scheduling is accomplished by scheduler located at eNodeB, which includes downlink scheduler and uplink scheduler. They are responsible for managing the downlink and uplink resource packet scheduling respectively. Compared to the WCDMA systems, in which packet scheduling is controlled by the RNC, packet scheduling in the LTE system can choose proper
