Claim Text:
1. A method to reduce power consumption in cellular communication networks through spectrum trading, the method comprising: determining a group of primary users (PUs) that are not associated with a primary base station (PBS) or a secondary base station (SBS); determining a PBS transmission power to serve a PU within the group; determining a bandwidth to be used by the SBS to serve the PU; deriving a power-bandwidth ratio for the PU by dividing the PBS transmission power to serve the PU by the bandwidth to be used by the SBS to serve the PU; determining whether a power consumption of the PBS is reduced by having the PU associated with the SBS based on the power-bandwidth ratio; and if the power consumption is reduced, associating the PU with the SBS, else associating the PU with the PBS.
