Abstract
In the present disclosure, CSI and/or a plurality of ACK/NACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. When the DCI trigger is received, the UE may transmit the CSI and/or GACK. In this way, HARQ feedback and/or CSI may be reliably communicated even if a CCA does not clear and/or UL subframes are unavailable. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In an aspect, the apparatus may be a UE. The apparatus monitors one or more subframes for a DCI trigger. In a further aspect, the apparatus receives the DCI trigger in a subframe. In another aspect, the apparatus transmits UCI using a subsequent subframe.
