Claim:
1. A radio communication method performed by a radio communication apparatus, the radio communication method comprising: storing a beam having a good characteristic and a beam having a bad characteristic on the basis of a result of beamforming setting; detecting a degradation of at least one of a transmission characteristic and a reception characteristic that occurs because of heat from one or more circuits; reserving a calibration period in response to detecting the degradation of the at least one of the transmission characteristic and the reception characteristic that occurs because of heat from one or more circuits; changing a beam to the beam having the bad characteristic in the reserved calibration period; performing calibration using the beam having the bad characteristic in the reserved calibration period; and changing the beam having the bad characteristic to the beam having the good characteristic after the reserved calibration period has elapsed, wherein the beam having the bad characteristic is the beam having the worst reception level on the basis of the result of beamforming setting.
