Abstract
A first radio node, Node1, in a wireless communication network transmits a signal to a second radio node, Node2, under a constraint of spectrum flatness—meaning a maximum variation of power of the transmitted signal, within a transmission bandwidth. Spectrum flatness configurations may be determined by a network node and transmitted to Node1. Alternatively, Node1 may determine a spectrum flatness configuration and transmit it to a network node. In either case, Node1 adapts one or more coefficients of a transmission filter such that a transmission to Node2 will be in accordance with the obtained spectrum flatness configuration, and then transmits a signal to Node2 using the transmission filter with the adapted coefficients.
