Abstract (en)
[origin: WO0243278A1] The present invention relates to an apparatus of dividing a multi-beam from a base station for several n sectors and combining vice versa in a mobile communication system. The present apparatus includes a multi-beam forming module consisting of n multi-beam forming means forming a received multi-beam from m antennas in a mobile communication system to m beams, which have different direction each other; a 180 DEG coupling module combining the (mXn) beams from the multi-beam forming module to (mXn)/2 beams; a switching module choosing each beam path of the beams from the 180 DEG coupling module; a 180 DEG phase shifting module shifting signal phase to strengthen a part of the beams outputted from the switching module; and a mixing module adapting characteristics of amplitude and phase of the beams while mixing them. According to the present invention, data traffic of a base station can be distributed equally among its n sectors.
