FLEXIBLE CARRIER UTILISATION

摘要

In the present invention, carrier pairs of one uplink carrier (UL1, UL2) and one downlink carrier (DL1, DL2) are provided with a flexible duplex frequency separation distance in a cellular communication system (1) operating according to a FDD concept. At least a first carrier pair used in the system has a different duplex frequency separation distance than a second carrier pair. The duplex frequency separation distance may vary within one cell (12H. J) and/or between different cells (12H, J) in the same system (1), preferably dependent on the traffic situation and preferably on a pre connection or per code basis. The increased flexibility in pairing different available uplink and downlink carriers makes it possible to match different kinds of asymmetries in the system (1) in order to increase the overall transmission capacity.
