Abstract

Resources of two frequency division duplex (FDD) frequency bands at a distance from each other are allocated for transmissions by a time division duplex (TDD) transmission method. The resources in the first FDD frequency band are allocated for FDD transmissions in the uplink and for TDD transmissions predominantly in the uplink as the primary transmission direction, and in a secondary manner in the downlink as the secondary transmission direction. The resources in the second FDD frequency band are allocated for FDD transmissions in the downlink and for TDD transmissions predominantly in the downlink as the primary transmission direction and in a secondary manner in the uplink as the secondary transmission direction. No resources are allocated for time periods of an allocation of resources for one of the secondary transmission directions in the first and second frequency bands, for FDD transmissions in the counter transmission direction to this secondary transmission direction.
