Various example embodiments are disclosed relating to contention window management in relay networks. In an example embodiment, a data unit transmitted from a network node based on a first contention window associated with a first network station may be received, for example, by the first network station located, for example, on a first level. The data unit may be forwarded to a second network station based on a second contention window associated with the second network station. The second network station may, for example, be located on a second level. The first network station may, for example, include a relay station and the second network station may, for example, include a base station.
