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.
