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: Embodiments of efeMTC synchronization signals for enhanced cell search and enhanced system information acquisition are described. In some embodiments, an apparatus of a base station (BS) is configured to generate a length-x sequence for an efeMTC synchronization signal, the length-x sequence configured for repetition in frequency domain within 6 physical resource blocks (PRB). In some embodiments, to generate the length-x sequence, the BS may be configured to select any one index of the set of root indices {1, 2, 63}, excluding the root indices 25, 29 and 34, to correspond to a different physical-layer cell identity (PCID). In some embodiments, the BS may be configured to encode RRC signaling to include a System Information Block (SIB) comprising configuration information for transmission of the efeMTC synchronization signal, and transmit the length-x sequence as the efeMTC synchronization signal in frequency resources according to the SIB.

Abstract: Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive, from a gNB, a narrowband physical downlink control channel (NPDCCH) that indicates a number of narrowband internet-of-things (NB-IoT) downlink subframes for a downlink scheduling delay of a narrowband physical downlink shared channel (NPDSCH) in one or more radio frames configured for time-division duplexing (TDD) operation. Subframes of the one or more radio frames may include uplink subframes, NB-IoT downlink subframes for downlink NB-IoT transmissions, and downlink subframes for other downlink transmissions. The UE may determine the downlink scheduling delay based on an earliest subframe for which a count of NB-IoT downlink subframes is equal to the number of NB-IoT downlink subframes indicated in the NPDCCH.

Abstract: Machines or networked devices such as internet of things (IoT) devices operate to generate an unlicensed IoT (U-IoT) communication or enhanced Machine Type Communication (eMTC) based on frequency hopping operations on different channels. An anchor channel can be configured to carry system information and paging messages for the U-IoT/eMTC communication on the different channels. The system information and paging messages can include essential system information such as a system information block MulteFire (SIB-MF) message. Physical channels can be configured to enable component carriers anchored to a long term evolution (LTE) licensed band, and entirely comprise unlicensed carrier components that are unanchored to any LTE component carrier in a standalone configuration to enable transmission of the U-IoT communication in standalone communications in an unlicensed band.

Abstract: Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a narrowband physical downlink control channel (NPDCCH) that includes an uplink scheduling parameter. The UE may determine an uplink scheduling delay for transmission of a narrowband physical uplink shared channel (NPUSCH) in accordance with time-division duplexing (TDD). The uplink scheduling delay may be based on a sum of a predetermined first number of subframes and a variable second number of subframes. The second number of subframes may be based on a window of variable size that starts when the first number of subframes has elapsed since reception of the NPDCCH, and ends when a number of uplink subframes has elapsed since the start of the window. The number of uplink subframes may be indicated by the uplink scheduling parameter.

Abstract: Downlink transmissions can be generated to schedule one or more Internet of Things (IoT) devices for communication on unlicensed channels via frequency hopping operations/procedures. An evolved NodeB (eNB) or a next generation NodeB (gNB) can perform a listen before talk (LBT) on the unlicensed channels that are scheduled for transmission by at least one of: one or more IoT devices or one or more user equipments (UEs). A preamble or a common physical downlink control channel (CPDCCH) can be transmitted to reserve the unlicensed channels for the IoT devices/UEs. The preamble or the PDCCH can include a duration of the duration to provide notice to other eNBs/gNBs or trigger the IoT devices of a successful LBT corresponding to the unlicensed channels.

Abstract: User equipment (UE) includes processing circuitry. To configure the UE for early data transmission (EDT), the processing circuitry is to encode a physical random access channel (PRACH) preamble for transmission to a base station as a PRACH procedure Message 1 (MSG1), the PRACH preamble including a request for EDT. A random-access response (RAR) message is decoded, the RAR message received from the base station as a PRACH procedure Message 2 (MSG2) and including an uplink (UL) grant for the EDT with a transmission block size (TBS) indicator. A TBS is selected from a plurality of available TBSs corresponding to the TBS indicator. UL data is encoded for the EDT to the base station as a PRACH procedure Message 3 (MSG3) using the UL grant and the selected TBS.
