Abstract: Provided is a wireless communication apparatus for a non-orthogonal multiple access communication system. The apparatus comprises: a power adjustment unit which is used, for at least some of user equipment included in the communication system, dynamically adjusting the sending power of each of the at least some of the user equipment for each sub-carrier according to channel state information about the communication system, in order that the at least some of the user equipment perform uplink data transmission on corresponding sub-carriers with the adjusted sending power. According to the disclosed apparatus, method and system, at least one of the following technical benefits could be obtained: increasing the channel capacity of the communication system; reducing the bit error rate during the communication; and reducing the interference between corresponding user equipment in the communication system.
