FIELD: radio engineering, communications.SUBSTANCE: in a radio communication system, which performs transfer in a subframe block, comprising two slots arranged serially in time, when performing preliminary coding by multiplication of a signal sent to multiple antennas by a weight coefficient of preliminary coding, a CDD technology is used to shift the phase so that the phase in the weight coefficient of preliminary coding cyclically changes along the axis of frequency. The value of the phase shift used by means of CDD is set to be changed by 2? in a dedicated resource block (1RB) of a local device, and a PVS technology is used so that the phase shift value between the weight coefficient W0 of the first half of the slot and the weight coefficient W1 of the second half of the slot in the subframe differs by ?.EFFECT: provision of the possibility to achieve the effect of spacing in multiple slots, together with prevention of planner complication or inefficient usage of resources, possibility to eliminate an event, in which in a certain slot SINR is considerably reduced, possibility to avoid reduction of demodulation efficiency.18 cl, 23 dwg |
