Abstract

A first type node (AP0, AP1, AP2) in a wireless communication system (1), wherein the first type node (AP0, AP1, AP2) is adapted to: —communicate with at least one other first type node (AP0, AP1, AP2) in the wireless communication system (1) over a corresponding channel (hA01, hA12), and —transmit a first plurality of signals (x11, x1i, X1N, X21, X2i, X2N−1) to the other first type node (AP0, AP1, AP2). In the case of the other first type node (AP0, AP1, AP2) requesting re-transmission of a failed signal (x11) in the first plurality of signals (x11, x′1i, X1N, X21, X2i, X2N−1), the first type node (APo, AP1, AP2) is further adapted to: —receive a limit of tolerable interference from the other first type node (APo, APi, AP2), and —re-send the failed signal (xn) in a second plurality of signals (x11, x′2i x′1i, X′1N, X′21, X′2N−1, X′2N, X2N; X11, x′2i, x′1i, X′1N, x′21, x′2N−1, X2N) to the other first type node (AP0, AP1, AP2) while sharing the spectrum for the failed signal (x11) with an additional signal (x′2i) without exceeding the limit of tolerable interference.
