There is provided a method of decoding an encoded uplink signal, in accordance with embodiments of the present invention. The method comprises a network node receiving an encoded uplink signal from a receive point, and decoding the encoded uplink signal using an estimated interference signal as side information input. The encoded uplink signal was encoded with a practically disconnected many-to-one encoding scheme. There is also provided a network node comprising a decoder. The decoder is configured to receive an encoded wireless uplink signal from a receive point, and decode the encoded wireless uplink signal using an estimated interference signal as side information. The encoded uplink signal was encoded with a practically disconnected many-to-one encoding scheme.
