技術說明

本發明涉及一種功率分配方法及使用所述方法的基地台，適用於非正交多重接取（non-orthogonal multiple access，NOMA）系統中傳送訊息給至少兩個用戶設備的基地台。本發明之方法包括下列步驟：配置第一用戶設備的第一傳輸功率小於第二用戶設備的第二傳輸功率，其中第一用戶設備的通道增益大於第二用戶設備；依據第一傳輸功率計算第一用戶設備的第一系統容量，且依據第二傳輸功率計算第二用戶設備的第二系統容量；將第一系統容量與第二系統容量相加以取得總系統容量；以及在最大化總系統容量的情況下計算第一傳輸功率與第二傳輸功率。 The disclosure proposes a method of power allocation and a base station using the same method. The method is applicable to a non-orthogonal multiple access (NOMA) system with its base station transmitting signal information to at least two user equipments. The method includes: setting a first transmit power of a first user equipment to be smaller than a second transmit power of a second user equipment, where the channel gain of the first user equipment is larger than that of the second user equipment; calculating a first system capacity of the first user equipment according to the first transmit power, and calculating a second system capacity of the second user equipment according to the second transmit power; summing the first system capacity and the second system capacity to obtain a sum capacity; calculating the first transmit power and the second transmit power to maximize the sum capacity.
