Abstract: In embodiments, data transmitters and data receivers use, in a first mode, a first hopping pattern and a second hopping pattern for a repeated transfer of data, and, in a second mode, a third hopping pattern for the single transfer of data, wherein the hopping patterns of the first mode and the second mode are different so that a collision probability in the repeated transmission of data by a further data transmitter in a respectively different mode may be decreased and the transmission reliability may therefore be increased.

Abstract: In embodiments, instead of a uniform (global) hopping pattern that is used equally by all data transmitters and data receivers of a communication system, data transmitters and the data receiver use an individual hopping pattern for the communication. This individual hopping pattern may depend on an operation and is therefore only used by the data transmitter and the data receiver themselves or by a small group of data transmitters and/or data receivers, which may significantly increase the interference immunity.
