技術說明

本發明揭露一種非正交多重接取系統中的功率分配方法，適用於一基地台。所述方法包括下列步驟：自第一使用者設備接收第一通道估測誤差參數，並自第二使用者設備接收第二通道估測誤差參數；配置前述第一使用者設備的第一最低傳輸率需求與前述第二使用者設備的第二最低傳輸率需求；依據前述第一通道估測誤差參數、前述第二通道估測誤差參數、前述第一最低傳輸率需求與前述第二最低傳輸率需求決定一功率分配因子；以及依據前述功率分配因子決定前述第一使用者設備的第一傳輸功率與前述第二使用者設備的第二傳輸功率。 The disclosure provides a power allocation method for non-orthogonal multiple access (NOMA) systems and a base station thereof. The method is adapted to the base station and includes the following steps: receiving a first channel estimation error parameter from first user equipment, and receiving a second channel estimation error parameter from second user equipment; configuring a first minimum rate requirement of the first user equipment and a second minimum rate requirement of the second user equipment; determining a power allocation factor according to the first channel estimation error parameter, the second channel estimation error parameter, the first minimum rate requirement, and the second minimum rate requirement; and determining first transmission power for the first user equipment and second transmission power for the second user equipment according to the power allocation factor.
