A method and device for channel allocation using channel allocation
tiering (CHAT), where radio resources are de-coupled from hardware
resources and the available hardware resource units in a cell are divided
into logical groups, "channel tiers". Each tier simultaneously utilizes,
partly or fully, the same radio resources. There is a first tier and at
least a second tier. In accordance with the invention terminals are
allocated to the first tier until a radio resource load threshold close
to but less than 100% is reached. Terminals are allocated channels on
said at least second tier based upon a terminal's interference
suppression capabilities, or the radio requirements of the service being
used on the terminal, or the radio location of the terminal, or a
combination of the above.
