A communications network (20) comprises a network coding node (24) and a network decoding node (26). A method of operating a communications network (20) comprises, at the network coding node (24), performing multi-domain network coding upon a first signal and a second signal to obtain a network coded signal. The first signal is modulated by a first modulation scheme and the second signal is modulated by a second modulation scheme. At least one of the first signal and the second signal includes information in a phase domain and information in an amplitude domain. The method further comprises transmitting the network coded signal over a link to a receiver (26) and performing multi-domain network decoding of the network coded signal as detected at the receiver (26) to obtain the second signal, the receiver knowing and using the first signal for the multi-domain network decoding.
