Method for extracting interference signal information and apparatus for the same

摘要

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.

1. A method for extracting interference signal information by a terminal in a communication system, the method comprising:
demodulating control channel signals received from a serving cell and an adjacent cell; 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 Identifier (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, from among the accumulated extracted terminal IDs; determining a reliability value of the filtered control channel signal; identifying the filtered control channel signal as a first interference signal, if the reliability value is greater than or equal to a first predetermined value; and extracting interference signal information based on the first interference signal.
