Abstract:
Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. A first method includes receiving feedback information from a user equipment (UE) via a primary component carrier (PCC) uplink in a licensed spectrum. A second method includes transmitting feedback information from a UE to an evolved Node B (eNB) via a PCC uplink in a licensed spectrum. The feedback information may address signals transmitted to the UE via a downlink in an unlicensed spectrum.
