Abstract

An apparatus is provided, including an observing function configured to observe an indication about the coverage status of a user equipment; a deciding function configured to decide, based on the indication, to switch into a coverage extension mode; a providing function configured to provide a scaling number in dependence of the coverage extension mode; an allocating function configured to allocate, for data to be transmitted to a user equipment, a first modulation and coding scheme, a first modulation order, a first size of a transport block, and a first number of resource blocks per transport block according to an orthogonal frequency division multiplexing technology, a reducing function configured to reduce a first size per resource block, being the quotient of the first size of the transport block and the first number of resource blocks per transport block, based on the scaling number, thus obtaining a second size per resource block, being the quotient of a second size of the transport block and a second number of resource blocks per transport block; and a scheduling function configured to schedule, for the data, the second size of the transport block and the second number of r…
