    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: A mobile communication device includes a table component, a table selection component, a control information component, and a communication component. The table component is configured to maintain two or more tables each having entries for a plurality of available modulation schemes. The table selection component is configured to select a selected table from one of the default table and the secondary table based on one or more of RRC layer signaling and MAC layer signaling and further based based on a control information format for control information received from the eNB. The control information component is configured to receive control information indicating a modulation and coding scheme from the selected table, and the communication component is configured to receive and process a communication from the eNB based on the modulation and coding scheme from the selected table.

    Abstract: Embodiments of the present disclosure may include monitoring, at a physical layer, for a physical uplink shared channel (PUSCH) trigger for a PUSCH transmission, determining, at the physical layer, the PUSCH trigger is not received, wherein a wireless communication device is not to perform the PUSCH transmission based on the determination that the PUSCH trigger is not received, and considering, at a medium access control (MAC) entity, the PUSCH transmission to have been performed. Other embodiments may be described and/or claimed.

    Abstract: Technology for a user equipment (UE), operable for an uplink partial subframe transmission on an unlicensed carrier is disclosed. The UE can select one or more uplink (UL) partial subframe configurations based on one or more prospective lengths of a listen before talk (LBT) period, wherein each prospective length of the LBT period provides a prospective starting time. The UE can encode data for each of the one or more UL partial subframe configurations to form one or more UL partial subframe configuration encodings. The UE can identify an actual LBT period. The UE can select one of the one or more UL partial subframe configuration encodings for UL transmission of the data on the unlicensed carrier based on the actual LBT period and a corresponding prospective starting time.

    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.
