A New Efficient Dynamic System Information Scheduling Strategy in TDD-LTE

The TDD-LTE system information which is also necessary to communicate each other well is a kind of important message between user equipment (UE) and eNodeB. Some important parameters are provided by system information to enable the UE to camp on a cell normally and access to common channel. The system information, , of course can provide the mobility management for UE in idle mode. On the base station side, there are two kinds of scheduling methods of in the TDD-LTE system, and they are fixed scheduling and dynamic scheduling. The MasterInformationBlock (MIB) and the SystemInformationBlockType1 use the fixed scheduling,while the dynamic scheduling is applied to other SystemInformationBlocks (SIB2~SIB13); and these system information are transmitted on the Downlink Shared Channel (DL-SCH). In consideration of using the radio resources reasonably and not affecting other downlink transmitted data,we proposed a dynamic scheduling strategy of system information based on the base station side.
