Abstract: An apparatus and a method relieve intercell interference in a wireless communication system. In a method for operating a transmission node, a first private message encoding a portion of transmission data of a neighbor transmission node is received. Weight for canceling the first private message of the neighbor transmission node received in a intended reception node is determined. The first private message of the neighbor transmission node multiplied by the weight, a common message encoding a portion of data to be transmitted to the intended reception node, and a second private message encoding the rest of the data are transmitted.

Abstract: A method and apparatus for optimizing average bit error probability via a deep multi-armed bandit in an orthogonal-frequency division multiplexing and index modulation system for low power communication are proposed. The method proposed in the present invention comprises: detecting BPSK symbols and subcarriers among all subcarriers; defining a combination of selected subcarriers as a subcarrier selection pattern; selecting the subcarrier selection pattern through learning to minimize the average bit error probability for all combinations of selected subcarriers; and updating a learning parameter of the subcarrier selection pattern selected through learning.
