| Summary: | 碩士 === 國立暨南國際大學 === 資訊工程學系 === 104 === LTE-Advanced (LTE-A) is one of the radio access technology standards developed by the 3GPP organization, and it is also the standard of 4G mobile data transmission technology at present. LTE-A provides up to 100MHz system bandwidth and 1Gbps transmission rate when users are static. In order to extend the coverage area and provide higher data transmission rates for user in cell edge, the concept of Relay Node (RN) was proposed in LTE-A. LTE supports both TDD (Time-Domain Duplexing) and FDD (Frequency-Domian Duplexing) modes. In LTE-TDD, the selection of Downlink-Uplink configuration is semi-statical, it may cause the the selected configuration is not suitable for traffic demand in eNB, and the same situation will be happened in RN device.
This thesis investigates how to select the appropriate backhaul subframe configuration according traffic demand in LTE-A TDD with Type-1 RN, and also proposes the adaptive schemes to select backhaul subframe configuration based on the traffic demand. By observing the performance evaluation, some proposed adaptive select backhaul subframe configuration schemes can improve the system throughput.
