    Abstract: An interference cancellation method and apparatus of user equipment in a cellular communication system is provided. The method includes receiving signals including a desired signal and an interference signal from one or more base stations; determining a maximum likelihood (ML) decision metric to determine a value “l” of a rank indicator (RI), a value “p” of a precoding matrix indicator (PMI), and a value “q” of a modulation (MOD) level of the interference signal; applying a logarithm to the ML decision metric, and applying a maximum-log approximation to a serving data vector and an interference data vector, which are included in the ML decision metric; determining the values of “l,” “p,” and “q” using the applied ML decision metric; and cancelling the interference signal from the received signals using the determined values of “l,” “p,” and “q.”

    Abstract: A method of transmitting data in a wireless communication, by a first Base Station (BS) is provided. The method includes receiving control information including information related to transmission of a Reference Signal (RS) of at least one second BS from the at least one second BS adjacent to the first BS and transmitting data by using a preset method based on the control information when an RS transmission mode of the at least one second BS is different from an RS transmission mode of the first BS.
