(54) Method and device for assigning reference signal sequences in mobile communications system


(57) A reference signal sequence assignment method and device are provided by which the influence of inter-cell interference can be reduced and the number of usable cyclic shifted sequences per sector can be increased. In a mobile communications system with a structure including multiple cells each including multiple sectors, a sequence assignment method is employed by which pseudo-orthogonal sequences used for reference signals are assigned to cells or sectors. According to this method, the multiple pseudo-orthogonal sequences are assigned to cells or sectors by using multiple repetition patterns.
