An apparatus includes a downlink signal differentiating unit is configured to receive a downlink signal and differentiate a type of the downlink signal. A public baseband processing unit is connected to the downlink signal differentiating unit and is configured to receive a public downlink signal obtained by the downlink signal differentiating unit by the differentiating, to encode and modulate the public downlink signal to obtain a public baseband signal, and to transmit the public baseband signal to a carrier unit. A traffic baseband processing unit is connected to the downlink signal differentiating unit, and is configured to receive a traffic downlink signal obtained by the downlink signal differentiating unit by the differentiating, to encode and modulate the traffic downlink signal to obtain a traffic baseband signal, and to transmit the traffic baseband signal to the carrier unit.

Apparatus and method for processing downlink signal

A method for energy saving in communication system, where a base station enters idle state if no residence of user equipment is detected in a cell, comprises: receiving, by the base station in idle state, a response signal from user equipment after receiving a paging signal sent by the base station with a period N times a length of a radio frame; switching, by the base station, to active state. An energy saving base station and a microcell access gateway are also disclosed. Since the method is independent of whether a user equipment has been sent a signal to a macro network, application scope is enlarged. Since whether to enter active state is determined according to the feedback of user terminal, whether there is residence of user equipment in the microcell can be sensed more accurately, improving accuracy of state switching and reliability of smart energy saving of the microcell.
