本文提出了在異質網路中考慮用戶通道狀況與公平性後,挑選數個用戶同時進行多用戶多輸入輸出與多點協調的混合式天線分配排程器,並以模擬方式提供各種傳輸模式下的數值比較作為排程方法的驗證。;Heterogeneous networks (HetNets) and Multi-user MIMO (MU-MIMO) are possible solutions for spectrum efficiency problem in the next generation mobile communication. They will coexist in the future.
However, the users in HetNets are sensitive to inter-cell interference, limit the system performance. Thus, 3GPP LTE designs enhanced inter-cell interference coordination (eICIC) and uses coordinated multi-point (CoMP) to cancel the interference.
Recently works consider MU-MIMO and CoMP as two transmission modes and switch them by scheduling, do not have a mode mix two. It cannot commit to find enough appropriate CoMP users in every scheduling duration, results to the existence of idle antennas .
In this paper, we proposed a mixed antenna allocation scheduler that take channel qualities and fairness in consider to select several users to do MU-MIMO and CoMP at once. We provide simulation results based on different transmission modes for comparing, verify the method we proposed.
