Abstract: Embodiments are provided for implementing network adaptation schemes, including small cell on/off adaptation and transmission power control. In an embodiment method for supporting network adaptation, a network component receives a discovery reference signal (DRS) from a network controller that is in a switch-off transmission mode. The network component then performs measurements according to the DRS, and reports the measurements to a network associated with the network controller. In return, the network component receives a radio resource control (RRC) signaling from the network. The RRC signaling includes configuration information allowing a connection between the network component and the network controller. The network component then connects with the network controller in accordance with the configuration information.
