dc.description.abstract近年來由於科技蓬勃的發展,4G網路的飛躍性進步,長期演進技術(Long Term Evolution, LTE)系統一值是個值得關注的話題,但因為手持式裝置的發送功率限制,正交分頻多工(Orthogonal Frequency-Division Multiple Access, OFDMA)系統過大的功率消耗不適宜移植至各式各樣的手持式移動裝置內,因此LTE系統選擇單載波分頻多工 (Single-carrier Frequency-Division Multiple Access, SC-FDMA)作為其主要的上行鏈路傳輸系統,然而SC-FDMA系統在排程的策略上,因為有連續資源塊的限制,無法沿用以往的OFDM系統機制,本篇研究提出基於用戶的確實需求,進行資源分配,考慮到用戶的佇列狀態、延遲額度、封包丟棄率,設計演算法以提升系統效能,改善整體傳輸效益。zh_TW
dc.description.abstractAccording to the transmission power constrain for uplink users in LTE system, we know that the edge users have better chances to be neglected than central users, and only receive minor share of the total resources. In this study, we discuss and analyze the utility of several kinds of different service flows in LTE-A network and design resource allocation and scheduling technology for these specific traffic streams under Single-carrier Frequency-Division Multiple Access (SC-FDMA) systems, which was implemented in LTE-A network for uplink transmission. We propose a hybrid scheduling algorithm that considers the buffer states, packetloss, and the delay bound of different service flows under the SC-FDMA system which assures uplink users of fair quality of service, and to meet the users’ needs.en_US
