Abstract
A transmission beam change method is disclosed for a wireless communication transmitter adapted to transmit an orthogonal frequency division multiplex (OFDM) signal using a transmission beam of a plurality of transmission beams available at the wireless communication transmitter. The method includes temporarily adapting an output power during a transmission beam change from one transmission beam to another transmission beam. In some embodiments, the transmission beam change is performed during a cyclic prefix (CP) of an OFDM symbol and the temporary adaptation is applied to only a part of the CP. Temporarily adapting the output power includes decreasing the output power to initiate the temporary adaptation and increasing the output power to terminate the temporary adaptation. In some embodiments, the temporary adaptation is performed during all transmission beam changes or only when an occurrence frequency of transmission beam changes is higher than a threshold value.
