具用戶排程之蜂巢式網路的可適性雙工切換演算法

Abstract

在這篇論文中，我們考慮了蜂巢網路中的用戶排程和雙工模式選擇策略。在本篇的蜂窩網絡中，基地台被允許以全雙工或半雙工模式運行，並在每個上行和下行鏈路上為一個半雙工用戶服務。在以前的工作中，我們提出了一個基於信道信息和其他小區的統計干擾信息的雙工切換標準。本論文中，我們討論了基於三種不同的用戶調度方法的雙工切換標準。第一種是比例公平調度，即選擇具有相對於其平均值的最佳信道條件的用戶。後面的最後兩種用戶排程方法--最小距離和最大接收功率功率--旨在獲得更高的功率增益。使用隨機幾何學，我們估計了其他小區的干擾，然後決定每個小區的雙工模式。小區的雙工模式。模擬結果表明，三種用戶排程方法的平均系統總速率比純全雙工和純半雙工有所提高。

In this thesis, we consider the user scheduling and the duplex mode selec-tion criterion in a cellular network. In our cellular network, the base station (BS) is allowed to operate in full-duplex (FD) or half-duplex (HD) mode and serve one HD user on the uplink and downlink channel, respectively. In pre-vious work, the authors proposed a duplex switching criterion based on the channel information within a cell and the statistical other-cell interference information. In this thesis, we discuss the effect of user scheduling on duplex switching. The first scheduling method we considered is proportional fair scheduling which chooses the user with the best channel condition relative to its average. The other two user scheduling methods - minimum distance and maximum received power - aim for higher power gain. Using stochastic geometry, we approximate the other-cell interference under the influence of user scheduling and use it to assist the decision of the duplex mode in each cell. The simulation results show thatthe proposed duplex switching method improves the average sum rate under the three user scheduling mechanisms over the pure FD and the pure HD schemes.
