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.
