The eNB may transmit traffic packets on an unlicensed channel in the unlicensed frequency band to one or more User Equipments (UEs) assigned to the unlicensed channel. The eNB may receive, on the licensed frequency band, interference indicators for the unlicensed channel from at least a portion of the UEs assigned to the unlicensed channel. In addition, the eNB may transmit, on the licensed frequency band, a multicast vacate channel control message for the unlicensed channel. The message may be for reception at one or more of the UEs assigned to the unlicensed channel.
