    Abstract: Disclosed in some examples are methods, systems, and machine readable mediums which reuse existing LTE functionality to rapidly signal UEs on the availability of a LTE-U cell. Using these techniques the on/off operation can be in the order of a few milliseconds (ms). Several techniques are disclosed herein, including use of component carrier (CC) specific Discontinuous Reception (DRX) signaling, PDCCH signaling, DL assignment based signaling, Physical Hybrid Automatic Repeat Request Indicator Channel (PHICH) signaling, Beacon signaling, and the like.

    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: Technology for a user equipment (UE) operable to perform channel state information (CSI) measurements in a License Assisted Access (LAA) system is disclosed. The UE can process information received from a base station in the LAA system. The information can be received within a downlink (DL) transmission burst from the base station. The information can indicate one of: a cell-specific reference signal (CRS) or channel state information reference signal (CSI-RS) transmission power offset value for the DL transmission burst, one or more subframes in the DL transmission burst for which the UE is to perform CSI measurements, or a subframe boundary of the DL transmission burst. The UE can perform a CSI measurement for the DL transmission burst based on the information received from the base station. Subframes of the DL transmission burst can be associated with a substantially similar transmission power.

    Abstract: Techniques for transmission of a physical downlink control channel (PDCCH) or enhanced PDCCH (EPDCCH) within a partial subframe of a license assisted access (LAA) burst are discussed. One example apparatus comprises a processor configured to generate a LAA burst; generate one or more downlink control channel messages that comprise at least one of PDCCH messages or EPDCCH messages; generate a physical layer encoding of the LAA burst comprising a first partial subframe, wherein the first partial subframe comprises a physical layer encoding of the one or more downlink control channel messages; and output the first partial subframe comprising the physical layer encoding of the one or more control channel messages to transmitter circuitry for subsequent transmission via an unlicensed carrier.

    Abstract: Devices and methods of reducing overall Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) of user equipment (UE) using a large amount of carrier aggregation are generally described. The UE may receive a subframe from an enhanced NodeB (eNB). The subframe may contain a physical downlink control channel (PDCCH) formed in accordance with a Downlink Control information (DCI) format. The DCI format may comprise a Downlink Assignment Index (DAI) for Time Division Duplexed (TDD) and Frequency Division Duplexed (FDD) operation. The UE may determine, dependent on the DAI, a number and ordering of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) bits to be transmitted on a Physical Uplink Shared Channel (PUSCH) and subsequently transmit the HARQ-ACK bits.

    Abstract: A device of a User Equipment (UE) includes a soft buffer including a plurality of soft buffer partitions to store a plurality of soft bits for a number of hybrid automatic retransmission request (HARQ) processes, wherein the number of HARQ processes includes first HARQ processes corresponding to a first Time Transmission Interval (TTI) Type of a first duration (TTI Type 1), and second HARQ processes corresponding to a second TTI Type of a second duration (TTI Type 2) shorter than the first duration. The device further includes processing circuitry to communicate with a base station in a cellular network, the processing circuitry further to effect a dynamic switching between a TTI Type 1 communication mode and a TTI Type 2 communication mode, and to selectively access the soft buffer partitions to perform, based on the switching, at least one of the first HARQ processes and the second HARQ process.

    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: 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.
