Abstract:
1. A method of operation of a basestation in a cellular communications network, the method comprising, in the basestation: detecting signals transmitted by other basestations of the cellular communications network; identifying carrier frequencies on which the detected signals are being transmitted by the other basestations; selecting a carrier for transmissions from the basestation, wherein the carrier selected for transmissions from the basestation has a bandwidth that partially overlaps with the carrier frequencies on which the detected signals are being transmitted by the other basestations; and setting a maximum downlink power for transmissions from the basestation, wherein the maximum downlink power is set based at least in part on a frequency offset between (1) a centre frequency of the selected carrier and (2) one of the identified carrier frequencies on which the detected signals are being transmitted by the other basestations.
