Some example embodiments may be directed towards a method in a network node, which may be comprised in a Radio Network, for transmitting a combined wireless communication signal. The combined wireless communication signal may comprise a primary and a secondary signal component. The method may comprise transmitting to an user equipment the secondary signal component according to a secondary transmission scheme such that the secondary signal component at least partially overlaps with the primary signal component with respect to a signal domain. The method may also comprise simultaneously, suppressing at least one portion of the secondary signal component during a transmission of the primary signal component.Some example embodiments may be directed towards a method in an user equipment, which may be comprised in a Radio Network, for estimating the combined communication channel. The method may comprise receiving the combined wireless communication signal. The primary and secondary signal components may be received according to a primary and secondary transmission scheme, associated with a primary and secondary domain, respectively. The method may further comprise estimating the primary channel component when the secondary signal component is suppressed.
