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: 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: 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: transmissions outside a transmission opportunity (TxOP) is disclosed. The UE can process an uplink (UL) opportunity received from an eNodeB during a defined transmission opportunity (TxOP). The UL opportunity can schedule UL information to be transmitted from the UE on one or more UL subframes that are outside the defined TxOP. The UE can initiate a listen-before-talk (LBT) procedure to be performed before the UL information is transmitted from the UE on the one or more UL subframes that are outside the defined TxOP. The UE can process the UL information for transmission to the eNodeB on the one or more UL subframes located outside the defined TxOP.

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: A method and apparatus is disclosed herein for resource allocation in a wireless communication system are disclosed. In one embodiment, the method comprises allocating portions of the resources available to a subset of base stations of the plurality of base stations to serve a subset of UTs from clusters of base stations with cluster sizes including at least one with two or more base stations, where each of the portions of resources are allocated to serve one UT via a user-dependent cluster of base stations; and scheduling UT transmissions over the subset of base stations and scheduling slots, wherein within each of the scheduling slots one or more user terminals are scheduled for transmission, each by its user-dependent cluster of base stations.
