Abstract:
In a method for the error-monitored transmission of data via interfaces of a multi-step communication system, the data is transmitted from a transmitter station to a data-receiving station via at least two relay stations which are connected therebetween and receive and further transmit the data parallel to each other. The data is retransmitted if the transmission has been insufficient due to a request from the receiver end and/or due to the lack of a confirmation from the receiver end. In order to increase performance while reducing power consumption of the system, the request or confirmation is generated only by the receiver station and is sent back to the transmitter station. The relay stations consequently do not generate any confirmations or requests.
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.
