    Abstract: A wireless communication method includes: receiving a wireless signal including a plurality of frames, wherein each of the plurality of frames includes a plurality of sub-frames and a current frame is initially a first one of the frames; a) performing a correlation calculation between each of the sub-frames of the current frame and each a plurality of reference signals to generate a plurality of current correlation values; b) respectively accumulating the current correlation values with previous correlation values to generate cumulative values respectively corresponding to the plurality of sub-frames of the current frame; determining whether an effective synchronization signal is detected, based on the current cumulative values; and setting the current frame to a next one of the frames, setting the previous correlational values to the current correlation values, and determining whether to resume to step a) based on the determination as to whether the effective synchronization signal is detected.

    Abstract: A method and apparatus are provided for extracting interference signal information. The method includes demodulating control channel signals received from serving and adjacent cells; decoding the control channel signals received from the serving cell to extract control information; decoding the control channel signals received from the adjacent cell; extracting, at each subframe, from the decoded control channel signals received from the adjacent cell, a terminal ID of the adjacent cell; accumulating the extracted terminal IDs; filtering only a control channel signal from among the control channel signals received from the adjacent cell corresponding to a terminal ID having an accumulation count that is greater than or equal to a threshold; determining a reliability value of the filtered control channel signal; identifying the filtered control channel signal as a first interference signal, based on the reliability value; and extracting interference signal information based on the first interference signal.
