1. A method performed by a network node for handling communication in a wireless communication network, the method comprising:
selecting a precoder based on mutual information related to channel capacity of a channel, the mutual information being computed in a closed-form computation within a set interval, selecting the precoder being further based on a mutual information gradient of a closed form computation, the mutual information gradient comprising a Gaussian-signal approximation; and
transmitting data over the channel using the selected precoder.
