Claim:
A method of scheduling uplink and downlink resources on at least one uplink frequency carrier, and at least one downlink frequency carrier, separated by a duplex distance, for transmission between at least one base station and at least a first and a second mobile terminal, the method comprising: determining a transmit power of the first mobile terminal for transmitting its uplink resources; determining a transmit power of the second mobile terminal for transmitting its uplink resources; if the transmit power of the first mobile terminal is higher than the transmit power of the second mobile terminal, allocating the uplink and downlink resources to the mobile terminals so that the duplex distance of the first mobile terminal is larger than the duplex distance of the second mobile terminal; if the transmit power of the second mobile terminal is higher than the transmit power of the first mobile terminal, allocating the uplink and downlink resources to the mobile terminals so that the duplex distance of the second mobile terminal is larger than the duplex distance of the first mobile terminal; wherein, if uplink and downlink resources are simultaneously scheduled on more than one uplink frequency carrier and more than one downlink frequency carrier across multiple frequency bands, said allocating comprises allocating the uplink and downlink resources to the mobile terminals so that the minimum duplex distance of the first mobile terminal and the second mobile terminal is maximized; wherein the allocating comprises allocating the at least one downlink frequency carrier outside an inter modulation frequency between the at least one uplink carrier frequency and a neighboring interferer for each mobile terminal, such that the inter modulation frequency is calculated according to: f UE — RX =2 *f interferer −f UE — TX or f UE — RX =2* f UE — TX −f interferer where f UE — RX is the downlink frequency carrier for the mobile terminal, f interferer is the frequency of the neighboring interferer, and f UE — TX is the uplink frequency carrier for the mobile terminal.
