<p>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 (104, 108, 110, 204, 208, 210, 220, 304, 308, 310, 320, 322, 324, 330, 332, 334, 404, 408, 410, 420, 422, 424, 430, 432, 434, 440, 442, 444, 450, 452, 454) based on a first contention window (416, 426, 436, 446, 456, 502, 510) associated with a first network station (204, 220, 304, 320, 330, 404, 420, 430, 440, 450) may be received (610), for example, by the first network station (204, 220, 304, 320, 330, 404, 420, 430, 440, 450) located, for example, on a first level. The data unit may be forwarded (620) to a second network station (204, 220, 304, 320, 330, 404, 420, 430, 440, 450) based on a second contention window (416, 426, 436, 446, 456, 502, 510) associated with the second network station (204, 220, 304, 320, 330, 404, 420, 430, 440, 450). The second network station (204, 220, 304, 320, 330, 404, 420, 430, 440, 450) may, for example, be located on a second level. The first network station (204, 220, 304, 320, 330, 404, 420, 430, 440, 450) may, for example, include a relay station (220, 320, 330, 420, 430, 440, 450) and the second network station (204, 220, 304, 320, 330, 404, 420, 430, 440, 450) may, for example, include a base station (204, 304, 404).</p> |
