Abstract:
An apparatus for increasing a gain in a downlink carrier-to-interference ratio in a cellular telecommunications network, with at least one base station antenna for transmitting a downlink signal and receiving an uplink signal, comprising:a first measuring means for measuring a downlink parameter associated with at least one of a downlink interference and a downlink coverage in a target cell, wherein said transmitted downlink signal is received by a mobile unit;a first determining means for determining a first tilt angle for a transmit pattern based upon said at least one downlink parameter;a second measuring means for measuring an uplink parameter associated with at least one of an uplink signal strength and an uplink interference, wherein said received uplink signal is transmitted by said mobile unit and received by said base station; anda second determining means for determining a second tilt angle for a receive pattern based upon said at least one uplink parameter.
