1. A power reception apparatus comprising:
a power reception unit configured to wirelessly receive power from a power transmission apparatus via a first antenna;
a first communication unit configured to communicate with the power transmission apparatus via the first antenna;
a second communication unit configured to communicate with the power transmission apparatus via a second antenna different from the first antenna; and
a determining unit configured to determine whether the power transmission apparatus is able to perform control communication by the second communication unit, based on information obtained from the power transmission apparatus via communication by the first communication unit, the control communication being communication for controlling wireless reception of power by the power reception unit,
wherein the second communication unit transmits a signal for establishing a communication connection by the second communication unit with the power transmission apparatus, based on the determination that the power transmission apparatus is able to perform the control communication by the second communication unit.
