    Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for multi-carrier listen before talk operations. In various embodiments, a transmitting device may assign one or more primary carriers to perform listen before talk (LBT) operations, with non-primary carriers performing a channel sensing operation at the end of the LBT operations of at least one primary channel. In various embodiments, the LBT operations at the primary carriers may use a shared random countdown number or an independent random countdown.

    Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for uplink grants and hybrid automatic repeat requests (HARQ) in communications systems. Some embodiments operate to determine that an unlicensed first channel is idle based on a sensing of the first channel for a first period of time. Such an embodiment may then generate a reservation signal on the first channel and an uplink grant for a first user equipment (UE). After the uplink grant is communicated, the embodiment senses the first channel to detect a physical uplink shared channel (PUSCH) transmission associated with the uplink grant. A HARQ acknowledgment or negative acknowledgement may be sent in various embodiments following the sensing.

    Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to enable scheduling UL transmissions on transmission opportunities outside of the UL grants or for multi-carrier UL scheduling. A communication component of the device can operate to process or generate communications on an unlicensed band or a licensed band in response to UL grants and indications provided via a DL transmission for scheduling. An eNB can provide indications to a UE for processing that indicate whether a transmission opportunity is on the same transmission opportunity as the UL grants or an external/outside transmission opportunity. The indications can further trigger an listen-before-talk (LBT) protocol, which can vary between a category 4 LBT or a single LBT interval that is shorter than the category 4 LBT, depending on the indication.
