Abstract
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 measurements from a previous time step (n) are used to allocate, in the following time step (n+1), an average power of all channels the connection uses as well as individual power settings in-between said channels. The average power is controlled using an outer fairness loop balancing the average channel power against average bit rate per channel. The individual power settings is controlled using an inner capacity loop allocating much power to good channels and restricted power to poor channels. Each loop has a respective target relation and the results of the loops are combined in order to determine transmission power in the next time step. 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.
