A method performed by a network node for performing a superposed transmission in a wireless communications network, wherein the superposed transmission comprises a first signal intended for a first wireless device from the network node and a second signal intended for a second wireless device from the network node that are superposed and transmitted simultaneously by the network node on the same transmission resources in the wireless communications network, the method comprising determining a first ratio of the total transmission power available for the superposed transmission, which the first ratio is to be used for the first signal in the superposed transmission, determining a second ratio of the total transmission power available for the superposed transmission, which the second ratio is to be used for the second signal in the superposed transmission; transmitting information indicating the first and/or the second ratio to at least the first wireless device in the wireless communications network, wherein the information indicating the first and/or the second ratio being provided dynamically through a Physical Downlink Control Channel, PDCCH, or an Enhanced Physical Downlink Control Channel, EPDCCH; transmitting information indicating a third ratio between an average transmission power available for the superposed transmission per Resource Element, RE, in the Orthogonal Frequency Division Multiplexing, OFDM, grid not comprising Cell-specific Reference Signals, CRS, and an average CRS transmission power per RE; and performing the superposed transmission with the total transmission power according to the third ratio, using a transmission mode comprising CRS, to the first and second wireless device (121, 122) simultaneously on the same transmission resources by transmitting the first signal using a transmission power according to the first ratio and by transmitting the second signal using a transmission power according to the second ratio. wherein the superposed transmission comprises a first signal intended for a first wireless device from the network node and a second signal intended for a second wireless device from the network node that are superposed and transmitted simultaneously by the network node on the same transmission resources in the wireless communications network, the method comprising determining a first ratio of the total transmission power available for the superposed transmission, which the first ratio is to be used for the first signal in the superposed transmission, determining a second ratio of the total transmission power available for the superposed transmission, which the second ratio is to be used for the second signal in the superposed transmission; transmitting information indicating the first and/or the second ratio to at least the first wireless device in the wireless communications network, wherein the information indicating the first and/or the second ratio being provided dynamically through a Physical Downlink Control Channel, PDCCH, or an Enhanced Physical Downlink Control Channel, EPDCCH; transmitting information indicating a third ratio between an average transmission power available for the superposed transmission per Resource Element, RE, in the Orthogonal Frequency Division Multiplexing, OFDM, grid not comprising Cell-specific Reference Signals, CRS, and an average CRS transmission power per RE; and performing the superposed transmission with the total transmission power according to the third ratio, using a transmission mode comprising CRS, to the first and second wireless device (121, 122) simultaneously on the same transmission resources by transmitting the first signal using a transmission power according to the first ratio and by transmitting the second signal using a transmission power according to the second ratio.
