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: Technology for a user equipment (UE) operable to process scheduled uplink (UL) transmissions is disclosed. The UE can process one or more uplink (UL) grants received from an eNodeB on a downlink (DL) subframe in a first transmission opportunity (TxOP). The UE can determine, based on the one or more UL grants, one or more UL subframes in at least one subsequent TxOP for an UL transmission from the UE. The UE can process the UL transmission for communication on the one or more UL subframes in the at least one subsequent TxOP.

Abstract: Technology for a Next Generation NodeB (gNB) operable to communicate over an anchor channel for Unlicensed Internet of Things (U-IoT) is disclosed. The gNB can encode control information for transmission on two discovery reference signal (DRS) subframes to a user equipment 5 (UE). The control information can be transmitted on an anchor channel having a set frequency for U-IoT in an adaptive frequency hopping system. The control information can include: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) transmission, and a system information block for MulteFire bandwidth reduced (SIB-MF10 BR).

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: Technology for a user equipment (UE) operable to perform downlink (DL) channel quality measurement reporting is disclosed. The UE can decode a system information block type y bandwidth reduced (SIBy-BR) received from an eNodeB. The SIB1-BR can instruct the UE to include a DL channel quality measurement report in a message 3 (Msg3) transmitted during a random access procedure between the UE and the eNodeB, wherein y is a positive integer greater than or equal to 1. The UE can determine a DL channel quality measurement for a DL channel between the UE and the eNodeB. The UE can encode the Msg3 for delivery over an uplink channel to the eNodeB. The Msg3 can be delivered during the random access procedure and can include the DL channel quality measurement report with the DL channel quality measurement.

Abstract: A method is provided to generate and control transmission of reference symbols in a synchronization subframe, wherein a reference symbol includes reference values mapped to a block of K subcarriers. The method includes generating data corresponding to a basic subsequence of K−R1−R2 reference values, where R1 and R2 are integers such that 1≤R1+R2

Abstract: Systems, devices, and techniques for indicating the number of repetitions for a downlink control information (DCI) message are described. A described technique includes transmitting an indication of a repetition number for a downlink control information (DCI) message having a predetermined format for transmit power control (TPC) of an uplink channel by a user equipment (UE); and transmitting, to the UE via a machine-type communications physical downlink control channel (MPDCCH), repetitions of the DCI message in accordance with the predetermined format and in accordance with the repetition number. The predetermined format can based on a DCI format 3 or 3A for bandwidth-reduced low-complexity or coverage enhanced (BL/CE) UEs.

Abstract: Methods, systems, apparatus, and computer programs, for activating cross-slot scheduling in user equipment (UE) to achieve power savings. In one aspect, the method can include actions of generating, by an access node, an RRC communication including one or more parameters that, when processed by the UE, configures the UE to forego use of computing resources to buffer for potential PDSCH transmission for a predetermined amount of time, encoding, by the access node, the RRC communication for transmission to the UE, and causing, by the access node, one or more antennae to transmit the encoded RRC communication to the UE.

Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for scheduling of multiple uplink transmissions in unlicensed spectrum. One embodiment involves receiving, at an eNB, a first uplink scheduling request from a UE, scheduling a plurality of uplink subframes on the unlicensed channel in response to the first uplink scheduling request, and initiating transmission of a first subframe to the first UE in response to the scheduling of the plurality of uplink subframes, wherein the first subframe comprises one or more downlink control indicators (DCIs) allocating the plurality of uplink subframes to the first UE.
