Patent ID: 8200266

Claim:
A method for use in a wireless communications system in which there is at least a first transmitter and at least a first and a second receiver as at least two users, and at least a first and a second channel for said at least first transmitter to transmit to said at least two users on, wherein the method uses at least two parameters lambda_i (λ i ), and comprises: defining a parameter q i,j , which represents the inverse channel quality for user u i and channel j; setting lambda_i (λ i )to be proportional to q_i, i.e., λ i =x_i*E(q_i), where x_i is a fixed or slowly changing parameter for user i; finding all channels for user u i such that q i,j ≦λ i but q i′,j >λ i′ , ∀i′≠i, and designating those channels to user u i ; if more than one user u i with q i,j ≦λ i for a channel j is found, then assigning that channel to the user u i that ensures the condition q i,j /q i′,j >λ i /λ i′ , ∀i′≠i; and if q i,j >λ i , ∀i, then leaving channel j unassigned.
