摘要： A communication apparatus is equipped with diversity reception function using a plurality of reception systems for receiving, from a transmission apparatus, information corresponding to reception quality. The reception quality is measured before switching between a first state in which the diversity reception function is active and a second state in which the diversity reception function is inactive. The measured value obtained by the measurement is changed in accordance with the state after the switching. The changed value is reported to the transmission apparatus as the reported value of the reception quality.
