Power control and channel selection in a multi channel communication system
A method for allocating power and channels to connections in a multi-channel access based wireless communication system in which each connection is acting independently of the other. The quality of each channel of a connection is measured at successive time steps (n, n+1).

The method is of distributed character and may execute on individual receiving nodes. Further, it may be applied in the up link or in the down link.
