Abstract

Embodiments provide a method for generating a hopping pattern for transmitting a plurality of sub-data packets in a communication system. The method has a step of deriving a hopping pattern from a binary sequence, wherein an autocorrelation function of the binary sequence has autocorrelation side maximums with a predetermined maximum value. The method further has a step of determining a maximum sub-data packet length for the plurality of sub-data packets in dependence on a total emission duration of the plurality of sub-data packets indicated by the hopping pattern, and a minimum value of a difference sequence of a sorted difference number series derived from the binary sequence.
