Provided are a method, apparatus and system for managing radio resources, which relate to the technical field of wireless communications. The apparatus comprises: a determination module for determining that it needs to change the state of an auxiliary cell of a user equipment (UE) to a state where the uplink is opened and the downlink is closed; and a changing module for changing the state of the auxiliary cell so as to enable the state of the auxiliary cell to be the state where the uplink is opened and the downlink is closed, wherein when the state of the auxiliary cell is the state where the uplink is opened and the downlink is closed, an uplink signal can be received by a base station to which the auxiliary cell belongs in the auxiliary cell, and a downlink signal can be transmitted by the base station to which the auxiliary cell belongs only in a subframe transmitting a discovery reference signal (DRS) in the auxiliary cell, the uplink signal comprising an uplink reference signal, uplink control signalling and at least one kind of uplink data, and the downlink signal comprising a downlink reference signal, downlink control signalling and at least one kind of downlink data. The present invention decreases the power overhead and interference of the base station. |
