Abstract: Described are mechanisms for eNB support of DRS in LA A, 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.

The processing circuitry may be configured to perform a listen-before-talk (LBT) procedure on one or more channels of an unlicensed spectrum of a secondary cell (SCell).

Abstract: Disclosed herein is an apparatus of a user equipment (UE) configured to communicate with an evolved Node B (eNB). The UE may include memory and processing circuitry coupled to the memory. The processing circuitry may be configured to decode control information received on one or more channels of unlicensed spectrum. The control information includes indication that a grantless uplink (UL) transmission is allowed without a prior UL grant. The processing circuitry is further configured to perform a listen-before-talk (LBT) procedure on the one or more channels of the unlicensed spectrum to determine if one of the channels is available. Upon determining the channel is available, the processing circuitry can encode UL control information and data for transmission using the grantless UL transmission. The grantless uplink transmission is an unscheduled transmission, performed on the channel without an UL grant.

Abstract: Technology for a user equipment (UE) operable to perform a physical random access channel (PRACH) procedure with an eNodeB is disclosed. The UE can select a PRACH preamble for transmission to an eNodeB during the PRACH procedure. The UE can perform a listen-before-talk (LBT) to determine whether an unlicensed channel is available. The UE can detect a LBT failure at the UE. The LBT failure can indicate that the unlicensed channel is unavailable to transmit the PRACH preamble during a PRACH opportunity. The UE can select new PRACH resources for a subsequent PRACH opportunity. The UE can be configured to perform a PRACH preamble transmission during the subsequent PRACH opportunity when the UE is not subject to the LBT failure.

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.

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.
