Abstract
The disclosure proposes a method of power allocation and a base station using the method. The method is applicable to a base station for transmitting information signals to at least two user equipments in a non-orthogonal multiple access (NOMA) system. 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 a 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; and calculating the first transmit power and the second transmit power based on maximizing the sum capacity.
