Abstract
Methods and arrangements for determining a next interlace having a next structure to be applied during a next transmission interval in an unlicensed spectrum are disclosed. The next structure is to be applied for a transmission over a wireless interface in a wireless communications network operating in an unlicensed spectrum, wherein a first interlace is applied during transmission in a first transmission interval and wherein the first interlace has a first interlace structure formed by a plurality of physical resource blocks, PRBs, that are arranged with a given subcarrier spacing in one of a set of interlaces. The method includes defining a frequency shift based on the number of PRBs per interlace and a maximum allowed power for a single interlace and determining the next interlace structure by shifting the first interlace structure by the defined frequency shift.
