- 초록
- A hybrid beamforming based cooperative transmission system may comprise comprising a centralized processor (CP), access nodes (ANs) connected to the CP, and fronthaul links connecting the CP to the ANs. The CP may provide an outer precoding matrix for a first AN of the ANs, which is derived from global statistical channel state information (CSI) generated from local statistical CSI collected from the ANs, to the first AN via the fronthaul link; and the first AN may configure a radio frequency (RF) precoder of the first AN based on the outer precoding matrix, and configure a digital precoder of the first AN based on local instantaneous effective CSI between the first AN and first terminals to be served by the first AN.
