【摘要】：在多業(yè)務的正交頻分多址(OFDMA)蜂窩系統(tǒng)中,為改善小區(qū)整體的吞吐量并提高多用戶之間傳輸數據的公平性,提出一種基于最優(yōu)調度優(yōu)先級進行資源塊分配的長期演進項目(LTE)下行分配方案。打破傳統(tǒng)資源分配過程中順序分配資源的束縛,將用戶與資源塊(RB)配對,優(yōu)先把服務質量最好的RB資源分配給相應的用戶,盡量保證用戶在各自有利的信道上傳輸數據。仿真結果表明,該方案在不增大丟包率的前提下,有效提高了系統(tǒng)的吞吐量和公平性指數,對LTE下行鏈路是一個很好的選擇。
[Abstract]:In the multiservice orthogonal frequency division multiple access (OFDMA) cellular system, in order to improve the overall throughput of the community and improve the fairness of the data transmission between multiusers, a downlink allocation scheme (LTE) is proposed for allocation of resource blocks based on the optimal scheduling priority, which breaks the sequence of resources allocated in the traditional resource allocation process. Binding, the user is paired with the resource block (RB) to prioritise the best RB resource to the corresponding user to ensure that the user transmits data on their own favorable channels. The simulation results show that the system effectively improves the system throughput and fairness index without increasing the packet loss rate, and is one of the LTE downlinks. A good choice.
