<p>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 ?. The method comprises: Defining (425) a parameter qi j, which represents the inverse channel quality for user ui, and channel j, Finding (430) all channels for user ui, such that qij = ?i, but qi'j > ?, Vi' ? i, and designate those channels to user u, If more than one user u, with qi, j i, that ensures the condition qi j/qI'j, > ?i/?i', Vi' ?i. If qi j > ?i, Vi, then (430) leave channel j unassigned Power levels and rates may also be allocated with the aid of the invention.</p> |
