| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 100 === The radio resource in LTE is made from RBs(Resource Blocks) which compose of frequency domain and time domain. To use the radio resource efficiently, many papers have been focused on the resource allocation method and hope not to waist the resources by way of a good resource allocation scheduling. Now, most of the resource allocation methods based on CQI(Channel Quality Indicator) are only focus on the system CQI values or only on RB CQI values. Otherwise, in LTE, the UE(User Equipment) which is located on the cell edge may have a bad signal because of some factors.
In order to solve the above-mentioned problems, we proposed a resource allocation method which is based on the type II relay networks and on the CQI called CBRA (CQI Based Resource Allocation). In our method, eNodeB (eNB) allocates RBs according to the CQI and allocated rate of a UE. We select RBs by using the 2 types of CQI to gain the number of selectable RBs of other UEs. In this way, we hope to gain the system throughput and the fairness. However, the model we proposed is built on a system whose eNB is placed in the center of a transparent relay network cell to improve the communication quality on the cell edge users.
