Abstract
Provided is a method for generating, by a base station, a common signal commonly required for surrounding terminals of the base station in a massive multiple input multiple output (MIMO) system. The base station generates data commonly required for the surrounding terminals. The base station generates a plurality of beamforming vectors using a time-domain constant amplitude (TCA)-frequency-domain constant amplitude (FCA) sequence having a constant size in a time domain and a frequency domain. Further, the base station generates a plurality of antenna streams corresponding to the common signal by multiplying the plurality of beamforming vectors by the data.
