Abstract: There is provided generating, at a cell configured for a first air interface protocol, a reference signal based on a cell identifier for a second air interface protocol. At the cell configured for the first air interface protocol it is determined an air interface resource allocation for the first air interface protocol based on the cell identifier for the second air interface protocol. The cell configured for the first air interface protocol transmits the generated reference signal according to the determined air interface resource allocation.

Abstract: In accordance with example embodiments of the invention there is at least an apparatus and a method to perform determining, by a network node, a repeater, and/or a user equipment of a communication network, a configuration message comprising an identified frequency range of at least one of a first communication link between a donor and a repeater or a second communication link between a user equipment and the repeater for a repeat transmission in the communication network; and communicating with at least one of the repeater or the user equipment an indication of the configuration message for configuration at the repeater and the user equipment of the at least one set of sub-carriers mapped with the at least one physical channel for the repeat transmission, wherein the configuration message is using at least a different frequency offset of supported radio frequency resources to map at least one set of sub-carriers of the at least one of the first communication link and the second communication link with at least one physical channel in supported radio frequency resources of at least one of the first communication link or the second communication link, and mapping comprises performing spectral modification of resources to cause at least one of: sub-carrier shifting, wherein a sub-carrier is selected for the repeater to frequency shift to another part of the spectrum, based on instructions by the network node, sub-carrier inversion, wherein sub-carriers' indices are inversed, based on an on/off decision by the network node, and wherein the spectral modification is causing the at least one set of sub-carriers with the at least one physical channel to have different spectral properties as compared to a target set of sub-carriers associated with at least one of the user equipment or the repeater.
