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 number of embodiments can describe the operation of a UE in an unlicensed spectrum. Operating a UE in an unlicensed spectrum can include processing a PDCCH transmission provided by an eNodeB to identify a resource for a transmission of the SR message and based on the resource identified in the PDCCH, generating a PUCCH transmission comprising the SR message for the eNodeB.

Abstract: A base station for secondary-cell (S-cell) operation in an unlicensed band is subject to listen-before-talk (LBT) rules. The apparatus generates S-cell discovery reference signal (DRS) that includes a primary synchronization signal (PSS) based on a cell ID associated with the base station, a secondary synchronization signal (SSS), a cell-specific reference signal (CRS), and optionally CSI-RS. Solutions are described for generating portions of the DRS to accommodate the placement of the DRS in arbitrary subframes.

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: 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: A User Equipment (UE) device operates to directly determine a target small cell for access or handover with the assistance of a macro cell network. The UE directly generates the connection and selects which small cell to access from among a subset of small cells chosen of a set of candidate small cells. The UE is provided dedicated assistance information from the evolved node B (eNB) or macro network device. The dedicated assistance information enables the UE to measure data from the candidate small cells within a heterogeneous network environment. The UE shares the measured data and connects directly to the selected small cell for an access or handover operation.

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: 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: Techniques for mobile communication in 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 LBT protocol can be generated as a one shot LBT within a two symbol duration of a potential downlink (DL) transmission burst, or multiple times within the two symbol duration. In response to an idle state detection, a discovery reference signal (DRS) can be transmitted. In response to the LBT protocol and the DRS transmission being misaligned, a reservation signal can be generated to reserve the unlicensed carrier for the DL transmission.
