Interference cancellation in wireless relaying network

According to the present invention, signal information representative of a first set of information that is at least once through at least one transmission link is stored as a priori known signal information. This is, in the node, may be previously received and / or detected information, own transmitted information related to the signal information available or in use. And signal information indicating a second set of information is received, wherein transmission of the first set of information interferes with the reception of the second set of information. At least part of the second set in spite of the interference, at least part of the information by utilizing a priori known signal information stored in the received information signal and the previous can be successfully detected. This information is detected by interference cancellation based on the received signal information and relevant parts of the a priori known information. A set of a priori known signal information is preferably updated by a new continuous storing the detected information. Signal information, the radio relay network, interference cancellation, the data packets.
