Claim of US Patent No. 10,194,439

1. A method comprising:receiving, by a first base station from a second base station, a first message comprising one or more first parameters identifying a first plurality of subframes as a listen-before-talk (LBT) subframe of the second base station;
selecting a second plurality of subframes as an LBT subframe by the first base station based on the one or more first parameters;
transmitting, by the first base station to the second base station, a second message comprising one or more second parameters identifying the second plurality of subframes as a listen-before-talk (LBT) subframe of the first base station;
transmitting, by the first base station to one or more wireless devices, at least one radio resource control (RRC) message comprising one or more third parameters identifying the second plurality of subframes as a listen-before-talk (LBT) subframe;
performing, by the first base station, an LBT procedure in a subframe in the second plurality of subframes; and
transmitting, by the first base station, a burst when the LBT procedure indicates a clear channel; and
wherein the burst is configurable to start in the subframe if the subframe is identified as an LBT subframe.
