Abstract
The invention discloses a transmission scheme for mobile communication devices scheduled in a cell of a network by a base station, whereas a user equipment (UE) powered by a power supply transmits a block of payload information defined by a limited transmission power over a contiguous total transmission time, whereas transmissions of consecutive blocks of payload information of one UE are separated by scheduling gaps resulting from scheduling of UE transmissions by base station. The object of the invention to introduce a transmission scheme that can improve and/or extend the power supply/battery lifetime of NB-IOT devices as well as reduce the size and cost of such cheap mass-market devices without reducing the network coverage or cell capacity will be solved by a new transmission scheme with a scheduling gap which has a variable length with a defined minimum time duration which corresponds to a power supply recovery time and whereas the scheduling gap is extended in order to increase the power supply recovery time, respectively.
