Method, arrangement and computer program product in a base station for modulating information intended for transmission to a terminal. The base station and the terminal are comprised within a wireless communication network. The information comprises first and second data blocks, where two USF values are to be sent across the first data block and the second data block. The first data block and first parts of the two USF values are modulated with a first modulation technique and the second data block and second parts of the two USF values are modulated with a second modulation technique.Further, a method, an arrangement and a computer program product in a terminal for demodulating information received from a base station are described. In addition, a method, an arrangement and a computer program product in a control node are described.
