A method for communication in a wireless telecommunication system, the method comprising: adaptively designating, by a network element following a frame-based communication protocol, for use as a secondary component carrier in a carrier aggregation scheme, at least a portion of radio resources on an unlicensed band, wherein the radio resources that are adaptively designated facilitate wireless communication, wherein the portion of the radio resources is not being used by another network element following a contention-based communication protocol; and characterized in that: the network element following the frame-based protocol determines a subframe in which the network element following the contention-based protocol is scheduled to transmit a beacon signal, the determination being based on information requested from and received from a user equipment, UE, in communication with the network element following the contention-based protocol, wherein, when the network element following the frame-based protocol is scheduled to transmit a downlink subframe concurrently with the subframe in which the network element following the contention-based protocol is scheduled to transmit the beacon signal, the network element following the frame-based protocol instead transmits a coexistence subframe, wherein no transmission occurs in a portion of the coexistence subframe during which the beacon signal is scheduled to be transmitted, and wherein, during the remainder of the coexistence subframe, a coexistence subframe-based blocking signal is transmitted to prevent a contention-based protocol transmission during a subframe immediately following the beacon signal subframe. adaptively designating, by a network element following a frame-based communication protocol, for use as a secondary component carrier in a carrier aggregation scheme, at least a portion of radio resources on an unlicensed band, wherein the radio resources that are adaptively designated facilitate wireless communication, wherein the portion of the radio resources is not being used by another network element following a contention-based communication protocol; and characterized in that: the network element following the frame-based protocol determines a subframe in which the network element following the contention-based protocol is scheduled to transmit a beacon signal, the determination being based on information requested from and received from a user equipment, UE, in communication with the network element following the contention-based protocol, wherein, when the network element following the frame-based protocol is scheduled to transmit a downlink subframe concurrently with the subframe in which the network element following the contention-based protocol is scheduled to transmit the beacon signal, the network element following the frame-based protocol instead transmits a coexistence subframe, wherein no transmission occurs in a portion of the coexistence subframe during which the beacon signal is scheduled to be transmitted, and wherein, during the remainder of the coexistence subframe, a coexistence subframe-based blocking signal is transmitted to prevent a contention-based protocol transmission during a subframe immediately following the beacon signal subframe.
