An evolved node B, eNB, for sharing unlicensed spectrum comprising: a first wireless interface for communicating with cellular devices, UEs, (106a-106k) over a control channel; a second wireless interface for communicating with the cellular devices, UEs, (106a-106k) over a communication channel on the unlicensed spectrum; a processor configured to: select a candidate set (106a, 106d, 106g, 106i) of cellular devices, UEs, from the cellular devices, UEs, served by the eNB to receive a set of messages over the communication channel; transmit (502, 704) a request, using the control channel, to the candidate set of cellular devices, UEs, to broadcast a clear to send, CTS, message using a wireless local area network, WLAN, protocol; receive (506, 706) a report over the control channel from a first subset of the candidate set of cellular devices, UEs, indicating a successful broadcast of the CTS message; receive (506, 706) a report over the control channel from a second subset of the candidate set of cellular devices indicating a failed broadcast of the CTS message, the second subset not overlapping the first subset of the candidate set of cellular devices and transmit (508, 710), using a cellular protocol over the communication channel, a subset of the set of messages that is directed to the first subset of the set of cellular devices UE (106a-106k). a first wireless interface for communicating with cellular devices, UEs, (106a-106k) over a control channel; a second wireless interface for communicating with the cellular devices, UEs, (106a-106k) over a communication channel on the unlicensed spectrum; a processor configured to: select a candidate set (106a, 106d, 106g, 106i) of cellular devices, UEs, from the cellular devices, UEs, served by the eNB to receive a set of messages over the communication channel; transmit (502, 704) a request, using the control channel, to the candidate set of cellular devices, UEs, to broadcast a clear to send, CTS, message using a wireless local area network, WLAN, protocol; receive (506, 706) a report over the control channel from a first subset of the candidate set of cellular devices, UEs, indicating a successful broadcast of the CTS message; receive (506, 706) a report over the control channel from a second subset of the candidate set of cellular devices indicating a failed broadcast of the CTS message, the second subset not overlapping the first subset of the candidate set of cellular devices and transmit (508, 710), using a cellular protocol over the communication channel, a subset of the set of messages that is directed to the first subset of the set of cellular devices UE (106a-106k). select a candidate set (106a, 106d, 106g, 106i) of cellular devices, UEs, from the cellular devices, UEs, served by the eNB to receive a set of messages over the communication channel; transmit (502, 704) a request, using the control channel, to the candidate set of cellular devices, UEs, to broadcast a clear to send, CTS, message using a wireless local area network, WLAN, protocol; receive (506, 706) a report over the control channel from a first subset of the candidate set of cellular devices, UEs, indicating a successful broadcast of the CTS message; receive (506, 706) a report over the control channel from a second subset of the candidate set of cellular devices indicating a failed broadcast of the CTS message, the second subset not overlapping the first subset of the candidate set of cellular devices and transmit (508, 710), using a cellular protocol over the communication channel, a subset of the set of messages that is directed to the first subset of the set of cellular devices UE (106a-106k).
