A method (400) for use in a wireless communications system, with a first transmitter (410) and (415) a first and a second user, and at least (420) first and second channels for the first transmitter to transmit to said two users on, which method uses a first Lagrange parameter λ. The method comprises: Defining (425) a parameter qij, which represents the inverse channel quality for user ui, and channel j, Finding (430) all channels for user ui, such that qij≦̸λi, but qij′>λ, Vi′≠i, and designate those channels to user u, If more than one user u, with qi, j<λ for a channel j is found, then assign (435) that channel to the user ui, that ensures the condition qij/qI′j, >λi/λi′, Vi′≠i. If qij>λi, Vi then (430) leave channel j unassigned Power levels and rates may also be allocated with the aid of the invention.
