Abstract:
1. A method for canceling interference in a communication system, the method comprising: receiving, by a first base station, a first reception signal from a first mobile station located in a cell of the first base station; delivering, from a second base station being adjacent to the first base station, information associated with a second reception signal to the first base station, the second reception signal received from a second mobile station located in a cell of the second base station to the second base station; determining by the first base station whether an error exists on the second reception signal by performing a cyclic redundancy check (CRC) operation on the second reception signal and examining a CRC result; re-generating an interference signal using the decoding information of the second reception signal when no error exists in the second reception signal, and performing interference elimination on the first reception signal using the re-generated interference signal; and determining, when an error exists on the second reception signal, whether a power measured for a third reception signal directly received at the first base station from the second mobile station satisfies a predetermined interference elimination condition, the interference elimination condition comprising whether the power of the third reception signal is larger than a sum of a power of background noise and a power of the first reception signal.
