Abstract: A system and method of subframe configuration in licensed-assisted access using long-term evolution (LAA-LTE) with carrier aggregation (CA). A wireless device such as an eNodeB (eNB) may transmit control information in a subframe from a secondary cell (SCell) in downlink control information (DCI) to a user equipment (UE). The SCell may operate in an unlicensed band. The control information may indicate at least one of a non-ending subframe in a data burst, an ending subframe, and a duration of the ending subframe. The duration may be one of a predefined number of orthogonal frequency-division multiplexing (OFDM) symbol durations, and the ending subframe may be a partial or full subframe. A partial ending subframe may use a time slot structure in a time division duplexing (TDD) scheme, e.g., downlink pilot time slots (DwPTS). The eNB may then transmit to the UE data in the subframe according to the control information.
