In a method and a transmitter data is transmitted to two mobile stations sharing the same frequency band and the same timeslot. The data is modulated using a quaternary symbol constellation. Further, the data is transmitted to two mobile stations multiplexed on a shared channel comprising two branches and the transmission power for the transmitted data is set in response to the relative gain of the two branches. Hereby, the total system interference is reduced. The method and transmitter further allows for a cellular radio system individual power control loops for the two sub-channels when the system uses MUROS.

A method in a radio base station for transmitting data to two mobile stations in the same slot, wherein the data is modulated using a quaternary symbol constellation and where the data is transmitted to two mobile stations multiplexed on a shared channel comprising two branches, where the branches correspond to the real and imaginary parts of one complex-valued baseband signal, wherein the transmission power for the transmitted data is set in response to the relative gain of the two branches.
A transmitter for a radio base station, said transmitter adapted to transmit data to two mobile stations in the same frequency band and timeslot, and to modulate data using a quaternary symbol constellation, and being adapted further to transmit data to two mobile stations multiplexed on a shared channel comprising two branches given by the real and imaginary parts of one complex-valued baseband signal, and to set the transmission power for the transmitted data in response to the relative gain of the two branches.
