The manner which transmits the polytopic dot cooperation data on the basis of the orthogonal kabaringu code

摘要

This invention regards the manner which transmits the polytopic dot cooperation data on the basis of the orthogonal kabaringu code. With execution configuration of this invention, the manner which transmits the daunrinku data at base station of the poly entry poly output systems is offered. This manner step and B. which decide the multiple antenna groups from the antenna of the A. multiple polytopic dot cooperation electrolysis cells using the orthogonal kabaringu code which differs, includes with the step which modulates the polytopic dot cooperation daunrinku data symbol between the electrolysis cells vis-a-vis each antenna group. The orthogonal kabaringu code has the length which does not exceed 2 times that of the number of antenna groups. When manner of this invention is used, as for base station and the user equipment, the polytopic dot cooperation electrolysis cell and antenna which differs group which differs, or it is possible, to distinguish the signal from the polytopic dot cooperation cluster which differs the polytopic dot cooperation electrolysis cell and antenna which differs with that, group which differs, or interference between the signals from the polytopic dot cooperation cluster which differs is decreased.
