    Abstract: A wireless device including a digital receiver configured to receive data via an antenna array, and to determine a load metric based on a load of subcarriers around reference subcarrier signals of a reference signal, and a controller configured to compare the load metric to a load threshold to determine whether the load of the subcarriers is less than a predefined level, and if the load of the subcarriers is less than the predefined level, identify at least one time point where the reference signal repeats itself during a symbol period, and control the antenna array to switch among the plurality of antenna beamforming patterns based on the at least one time point.
