Abstract
Disclosed are dual mode beamforming methods and apparatuses for the same. An exemplary embodiment of the dual mode beamforming method may comprise obtaining a boundary equation generated based on mean channel gains (MCGs) and spatial correlation coefficients (SCCs) for a plurality of antennas of a plurality of base station; obtaining, from the plurality of base stations, MCGs of respective antennas equipped in each of the plurality of base stations and a SCC of a plurality of antennas equipped in at least one base station of the plurality of base stations; and determining a beamforming mode based on the boundary equation, the MCGs and SCCs obtained from the plurality of base stations. Therefore, a co-located beamforming or a distributed beamforming can be performed selectively according to a radio communication environment.
