Abstract: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.

Abstract: Narrowband Physical Downlink Control Channel (PDCCH) implementations are discussed. An example Evolved NodeB (eNB) comprises a memory storing instructions, a processor configured to execute the instructions, and a transmitter circuit. The processor is configured to determine at least one of downlink or uplink scheduling for one or more machine-type communication (MTC)-enabled user equipments (UEs); to generate, based at least in part on the determined scheduling, one or more MTC-physical downlink control channel (PDCCH) signals (M-PDCCH signals) associated with the one or more MTC-enabled UEs; and to perform channel coding, multiplexing, and scrambling of the one or more M-PDCCH signals. The transmitter circuit is configured to map the one or more M-PDCCH signals to resource element groups (REGs) in order of increasing subcarrier followed by orthogonal frequency division multiplexing (OFDM) symbol and to transmit the one or more M-PDCCH signals via a narrowband bandwidth of less than 1.4 MHz.

The UE can decode a signal, received from a next generation node B (gNB), that includes a resource element group (REG) bundling size for a first CORESET. The UE can decode a signal, received from the gNB that includes a REG bundling size for a second CORESET. The UE can decode a control message contained in one or more REGs in one or more of the first CORESET or the second CORESET.

Abstract: Embodiments of a user equipment (UE) and method for resource allocation and device-to-device (D2D) discovery hopping are generally described herein. In some embodiments, the UE may receive signaling from an enhanced node B (eNB) indicating discovery resources to transmit discovery signals on within an LTE operation zone. The discovery resources may include a discovery zone which may comprise a plurality of physical resource blocks (PRBs) and a plurality of subframes. The UE may transmit a discovery signal for receipt by one or more other UEs for D2D discovery within some of the PRBs of the discovery zone. The PRBs for the transmission of the discovery signal may be determined in accordance with a hopping mode to provide increased frequency diversity within a bandwidth of the discovery zone. The hopping mode may comprise intra-subframe hopping, inter-subframe hopping or joint intra/inter-subframe hopping.

Abstract: Systems, apparatus, user equipment (UE), evolved node B(eNB), and methods are described for machine-type communications (MTC) with early termination of repeated transmissions. In MTC implementations with narrow bandwidth, significant numbers of retransmissions may be scheduled based on channel quality measurements. If data is successfully decoded at a receiving device while a significant number of retransmissions remain, system resources are wasted. Embodiments described herein thus use downlink control messaging or intermediate hybrid automatic repeat request (HARQ) messaging for early termination of repeated messages.
