摘要： The present invention relates to a method and network device for transmitting data through a wireless transmission link using at least two reception beams. A recep-tion beam through which the data has been received is determined and a modula-tion code for modulating the data is allocated according to the determined recep-tion beam. Thereby, a specific code, e.g. scrambling code, can be assigned to a user equipment (50) depending on the beam it is connected to. Using this strategy for code assignment, own-cell signals received under one reception beam can be orthogonal assuming a synchronized transmission scheme. Signals received un-der another reception beam using another code will not be orthogonal, but this interference contribution is suppressed by the spatial filtering gain offered by the beamforming antenna system.
