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: Techniques for communication of a partial subframe and properties related to the partial subframe of a plurality of subframes in licensed assisted access (LAA) for an unlicensed frequency band are discussed. A network device (e.g., an evolved NodeB, or other cell network device) can generate a listen before talk (LBT) protocol in order to determine whether an unlicensed carrier of a secondary cell device is idle or busy. The evolved Node B (eNB) can communicate starting or ending partial subframes in a downlink transmission, and a user equipment (UE) can process partial subframes based on the communications and a scheduling policy.

Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to enable the assigning of different listen-before-talk (LBT) priority classes or levels within a same DL transmission for scheduling UL transmissions, either in the same transmission opportunity as the UL grant or another transmission opportunity outside of the UL grant. Other data elements or traffic of the DL transmission can be multiplex with the UL grant, such as LBT parameters or a PUSCH, while each can be separately and selectively assigned different or equivalent LBT priority classes. 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 on a first transmission opportunity.

Abstract: transmissions outside a transmission opportunity (TxOP) is disclosed. The UE can process an uplink (UL) opportunity received from an eNodeB during a defined transmission opportunity (TxOP). The UL opportunity can schedule UL information to be transmitted from the UE on one or more UL subframes that are outside the defined TxOP. The UE can initiate a listen-before-talk (LBT) procedure to be performed before the UL information is transmitted from the UE on the one or more UL subframes that are outside the defined TxOP. The UE can process the UL information for transmission to the eNodeB on the one or more UL subframes located outside the defined TxOP.

Abstract: Techniques for contention window size (CWS) adaptation (CWSA) are discussed. One example apparatus can comprise a processor that can receive HARQ messages UEs in response to PDSCH transmissions in one or more reference subframes. The HARQ messages can comprise HARQ-ACK values that denote a HARQ-ACK state for a transport block associated with License Assisted Access (LAA) operation, wherein each of the HARQ-ACK states is one of a DTX state, an ACK state, a NACK state, or an "any" state. The processor can also; determine a metric value for each of the HARQ-ACK states; calculate a CWS adjustment metric based on the determined metric values; increase a CWS to a next higher allowed value when the CWS adjustment metric is greater than or equal to a threshold; and reset the CWS to a minimum allowed value when the CWS adjustment metric is less than the threshold.
