    Abstract: Described is an apparatus of an Evolved Node-B (eNB) operable to communicate with a User Equipment (UE) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process one or more configuration transmissions from the eNB carrying one or more parameters for Grantless Uplink (GUL) transmission. The second circuitry may be operable to determine one or more GUL subframes of an acquired Maximum Channel Occupancy Time (MCOT) on time-domain resources allocated for GUL transmission from the UE. The third circuitry may be operable to generate a GUL transmission during the one or more GUL subframes of the acquired MCOT in accordance with the one or more parameters for GUL transmission.

    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: 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: Technology for an eNodeB operable to perform downlink (DL) transmissions using a Long Term Evolution (LTE) control region of a subframe for enhanced machine type communication (eMTC) is disclosed. The eNodeB can encode a system information block type 1 bandwidth reduced (SIB1-BR) for transmission 5 to a bandwidth reduced low complexity or coverage enhancement (BL/CE) user equipment (UE). The SIB1-BR can include an indication that the LTE control region in the subframe includes information for at least one of a machine type communication (MTC) physical downlink control channel (MPDCCH) transmission or a physical downlink shared channel (PDSCH) transmission. 10 The eNodeB can encode at least one of the MPDCCH transmission or the PDSCH transmission for delivery in a downlink over the LTE control region in the subframe to the BL/CE UE.

    Abstract: The present disclosure provides for a user equipment (UE) operating in an unlicensed spectrum in time division duplex (TDD). Operating a UE in an unlicensed spectrum in TDD can comprise generating a bitmap message. Generating a bitmap message can include accessing a bitmap comprising a plurality of positions based on a plurality of supported HARQ processes including the HARQ process, mapping a HARQ process identifier (ID) of the HARQ process to a position from the plurality of positions of the partitioned bitmap, and generating a bitmap message comprising the ACK/NACK message in the position of the bitmap corresponding to the HARQ process ID.

    Abstract: Systems and methods of enabling sub-PRB allocation for an efeMTC UE are described. The efeMTC UE transmits to an eNB or gNB support for a sub-PRB PUSCH transmission in a capability information element of a RRC message. The RRC message is transmitted after transmission of message 3 of the RACH procedure. The efeMTC UE receives semi-statistical dedicated RRC signaling that contains a sub-PRB configuration that is dependent on a sub-PRB maximum PUSCH channel bandwidth, a CE mode, a RL configured for the PUSCH and a TDD configuration and a sub-PRB PUSCH transmission allocation. The efeMTC UE transmits a sub-PRB PUSCH transmission on the sub-PRB PUSCH transmission allocation.
