    Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for license assisted access (LAA) communications on an unlicensed channel. The eNB determines if a subframe to be transmitted is a partial subframe, and if the subframe is not a partial subframe, constructs the subframe to contain both a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) at fixed symbol positions within the subframe. In further embodiments, the eNB determines if a last subframe of a downlink (DL) transmission burst to be transmitted is a partial subframe, and if the subframe is not a partial subframe, constructs the subframe to contain a discovery reference signal (DRS) for transmission.

    Abstract: Licensed assisted access (LAA) uplink (UL) transmissions can be performed using UL scheduling, enhanced node B (eNB) listen before talk (LBT), and user equipment (UE) LBT. A scheduling of a UE for UL transmission can include different procedures for a UE to perform LBT before UL transmission. These procedures can be classified as: i) a scheduled UE performing no LBT for UL transmission, ii) a scheduled UE performing fast LBT (as compared to the eNB) with a more aggressive choice of parameters than the eNB and iii) a scheduled UE performing LBT using parameters as used by the eNB for LBT. In some embodiments, the UL grant transmission by the eNB occurs in the unlicensed band after a successful LBT procedure at the eNB.

    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: Techniques for channel state information (CSI) reporting are discussed. One example apparatus at a user equipment can derive, for one or more subframes of a license assisted access (LAA) secondary cell (SCell), one or more channel measurements based on reference signals (e.g., cell-specific reference signals (CRS) or CSI reference signals (CSI-RS)), in those subframes; generate CSI that comprises a channel quality indicator (CQI) based on an average of the one or more channel measurements from multiple subframes comprising a first subframe and a later second subframe, wherein each orthogonal frequency division multiplexing (OFDM) symbol of a second slot of the first subframe is occupied, wherein each of a first three OFDM symbols of the second subframe are occupied, and wherein each OFDM symbol between the first subframe and the second subframe is occupied; and generate a CSI report that indicates the set of CSI parameters.

    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: 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.
