1. A method for communication of information in a communication channel, wherein the communication channel comprises at least one main band and an adjacent guard band, the method performed by a transmitter node, in a wireless communication network, wherein the method comprises:
determining whether to transmit information in the guard band, based on one or more configured transmission parameters associated with the transmitter node;
upon the determination to transmit information in the guard band, determining transmission power for frequency resources in the guard band based on a spectral mask defining a power density limit for frequencies in the guard band, by setting a power spectral density (PSD) for the frequency resources in the guard band below the spectral mask in the guard band; and
transmitting, to a receiver node, first information on the frequency resources in the guard band according to the determined transmission power, and transmitting second information on frequency resources allocated in the main band.
