METHOD OF REPEATEDLY USING AND ARRANGING OPTIMAL PILOT SIGNAL AT MULTI-CELL MASSIVE MIMO SYSTEM

摘要

The present invention relates to a technology of handling the length and arrangement method of a pilot signal to be arranged to present users when a massive MIMO situation for a base station is assumed at a multi-cell mobile communications system. More specifically, the present invention relates to a method of arranging the length of a pilot signal that needs to be used and a method of arranging the pilot signal to multiple cells when an available signal dimension is given within a time when a communications channel determined depending on communication situations is sustained in order to maximize communications efficiency. As a result, the present invention relates to a technology of handling a method of repeatedly using and optimally arranging an optimal pilot signal according to communications channels and the gathering structures of multiple cells at a communications system using a pilot signal. The method comprises the steps of: dividing an L number of cells into an n number of partitions (1=n=L); and arranging pilot signals by allowing at least two cells of the L number of cells to share different sets of pilot signals.;COPYRIGHT KIPO 2016
