A communication method for a communication station to transmit time division duplex frames includes transmitting a capability of supporting a dynamic radio dormant mechanism to one or more communication devices; collecting at least one of a traffic information, an energy policy, an energy status and an interference policy for determining whether one or more predetermined dormant criteria are met; transmitting one or more signaling messages to the one or more communication devices to perform the dynamic radio dormant mechanism; and stopping at least one of a transmission of a downlink traffic in a downlink subframe configured to be dormant and a reception of an uplink traffic in an uplink subframe configured to be dormant. Each of the time division duplex frames comprises a plurality of subframes.
