Channel availability is uncertain when employing an unlicensed carrier. In particular, it may be difficult to schedule grants in advance because of the uncertainty associated with future channels availability. Accordingly, scheduling UL and/or DL grants exclusively using self-scheduling or exclusively using cross-carrier scheduling for utilizing an unlicensed carrier may result in wasted communication opportunities. Aspects disclosed herein whereby an eNB may use licensed and unlicensed carriers to communicate downlink grants and uplink grants for an unlicensed carrier to a UE. In one aspect, the eNB may use an unlicensed carrier to communicate downlink grants for downlink communication on the unlicensed carrier, and may use a licensed carrier to communicate uplink grants for uplink communication on the unlicensed carrier.
