摘要： Method and controller are disclosed for receiving beam control in MIMO system. According to an embodiment, a measured power of a signal is obtained from a power meter. The signal is generated by a beamforming combiner by combining multiple inputs from an antenna array, and represents a first receiving beam with a first gain and a first pointing direction. Whether to apply beam gain control is judged based on the obtained power. In response to a positive judgment result, a target gain is determined. The target gain is converted to a target beamforming parameter. The target beamforming parameter is provided to the beamforming combiner, such that the first receiving beam is replaced by a second receiving beam with the target gain and the first pointing direction. A radio unit comprising the controller and a base station comprising the radio unit are also disclosed.

摘要： Embodiments of the present disclosure relate to a method and device for beam forming. In example embodiments， a plurality of signals are obtained from a plurality of receiving antennas. The plurality of signals are grouped into a first set of signals and a second set of signals. An automatic gain control (AGC) is disabled for each signal in the first set of signals， and the AGC has been enabled for each signal in the second set of signals. Then， for beam forming associated with the plurality of receiving antennas， beam weights are determined by applying a first set of signal weights to the first set of signals and applying a second set of signal weights to the second set of signal weights. The first set of signal weights are greater than the second set of signal weights. In this way， negative effects due to the AGC processing may be mitigated in the beam forming.
