1. An apparatus, comprising:
a mobility processor;
a sounding transceiver, configured to periodically transmit a sounding packet to a beamformee through a downlink channel from the apparatus to the beamformee according to a first sounding interval;
a sounding-control circuit, configured to control the first sounding interval in response to a control signal from the mobility processor; and
a mobility-calculating circuit;
wherein in response to the sounding transceiver receiving a data packet or a report packet from the beamformee, the mobility-calculating circuit obtains a current first channel profile from the received data packet or the received report packet,
wherein the mobility processor adaptively adjusts the first sounding interval according to a first mobility indicator which is calculated according to the current first channel profile and a previous first channel profile.
