Abstract: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to encode a Non-scheduled Physical Uplink Control Channel (N-PUCCH) in an Uplink (UL) burst transmission, and to encode a Physical Uplink Shared Channel (PUSCH) in the UL burst transmission. The second circuitry may be operable to initiate the UL burst transmission subject to a Listen-Before-Talk (LBT) protocol on a channel of the wireless network. The UL burst transmission may be initiated without a UL grant received from the eNB.

Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for scheduling of multiple uplink transmissions in unlicensed spectrum. One embodiment involves receiving, at an eNB, a first uplink scheduling request from a UE, scheduling a plurality of uplink subframes on the unlicensed channel in response to the first uplink scheduling request, and initiating transmission of a first subframe to the first UE in response to the scheduling of the plurality of uplink subframes, wherein the first subframe comprises one or more downlink control indicators (DCIs) allocating the plurality of uplink subframes to the first UE.

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: 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.

Abstract: Described are mechanisms for eNB support of DRS in LAA, in which DRS is transmitted at one or more DRS occasions within a DMTC window, subject to LBT. In some embodiments, an eNB may include hardware processing circuitry comprising an antenna port, a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine a DMTC window of a wireless communication channel. The second circuitry may be operable to initiate one or more CCA checks through an antenna coupled to the antenna port prior to a DRS occasion within a DMTC time window. The third circuitry may be operable to initiate a DRS transmission through the antenna within the DMTC window upon a CCA check of the set of one or more CCA checks sensing that the wireless communication channel is idle. Also described are mechanisms for proactive support of DRS in LAA.

Abstract: An eNodeB (eNB), user equipment (UE) and method of providing a quasi-orthogonal multiple access (QOMA) resources are generally described. The UE receives allocation of orthogonal multiple access (OMA) and non-OMA (NOMA) resources. The UE transmits data up to a maximum NOMA rate and NOMA Modulation and Coding Scheme (MCS) using the NOMA resources without receiving an explicit transmission grant from the eNB. The eNB may allocate multiple NOMA regions associated with different maximum rates, MCSs, number of UEs, UE types, applications and sizes. If the data exceeds the NOMA conditions or the UE is unable to transmit data using the allocated NOMA resources or does not receive an acknowledgement from the eNB regarding reception of the transmitted data, the UE may request an explicit grant of the OMA resources from the eNB and, upon receiving an allocation of the OMA resources, subsequently transmit the data using the allocated OMA resources.

Abstract: Disclosed in some examples are systems, machine-readable media, methods, and cellular wireless devices which implement a Listen-Before-Talk (LBT) access scheme for a device operating according to a cellular wireless protocol in an unlicensed channel. A cellular wireless device may utilize the cellular wireless protocol in the unlicensed channel after the LBT access scheme has determined that a channel (a defined range of frequencies) in the unlicensed channel is idle for a particular period of time.

Abstract: Radio frame configuration circuitry for use in a device of a wireless communication system is provided. The radio frame configuration circuitry uses control circuitry to select between a plurality of different time-division duplex, TDD, configurations for a radio frame having slots with a configured duration. Transceiver circuitry performs TDD communications based on selections made by the control circuitry such that an average periodicity of switching between transmission of information and reception of information during the TDD communication is the same despite switching between different ones of the plurality of different TDD configurations. The radio frame configuration circuitry can be incorporated in a UE or an eNodeB or a Peer Radio Head. A corresponding method is provided.
