The Research And Realization Of Resource Schedule Based On QoS Guarantee In LTE System

3GPP long term evolution system requires the eNB to providethe higher uplink datatransfer rate in a limited spectrum bandwidth for more users, and to meet the users all kinds ofQoS requirements.The key to achieve the QoS is whether to use an effective MAC layerresource scheduling mechanism.A good realization of resource scheduling mechanism canoptimize to ensure the user’s QoS requirements and make a fully used of limited resources.The uplink resource scheduling technology includes resources of scheduling algorithmand related signaling support.Scheduling algorithm is implemented based on UE and RBscheduling algorithm,compared with the three classic schedule algorithms.The adoption ofthe token bucket algorithm can makesure that the low priority RB get resources allocation andmake the process be designed.On the basis of analysising the uplink related resourcescheduling signaling which have been designed and realized in the the uC/OS-II protocolstack bying C language and realized stable operation in the ARM926EJ-S processor for a longtime.designed the uplink resource scheduling control signaling between layer1and layer2,scheduling request signaling and Buffer State Report signaling makes the eNB scheduler toget the correct scheduling instructions.Through the protocol stack emmi101test module in the eNB side to test the software, testresults shown that the realization of uplink resource scheduling signaling support not onlyreached the requirements of function design,but also achieved the goal of an informationinteraction between RLC and the other moduler of MAC.
