Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

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: Embodiments described herein include user equipment (UE), evolved node B (eNB), methods, and systems for narrowband Internet-of-Things (IoT) communications. Some embodiments particularly relate to control channel communications between UE and eNB in narrowband IoT communications. In one embodiment, a UE blind decodes a first control transmission from an evolved node B (eNB) by processing a first physical resource block comprising all subcarriers of the transmission bandwidth and all orthogonal frequency division multiplexed symbols of a first subframe to determine the first control transmission. In various further embodiments, various resource groupings of resource elements are used as part of the control communications.

Abstract: An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) system is disclosed. The apparatus comprises a processing circuit configured to determine an NR-physical uplink control channel (PUCCH) resource to be utilized by the UE, for a transmission of a hybrid automatic repeat request (HARQ)-acknowledge (ACK) feedback message to a gNodeB, wherein the determined NR-PUCCH resource comprises a HARQ-PUCCH resource. In some embodiments, the HARQ-ACK feedback message comprises a feedback message generated at the UE in response to processing a downlink (DL) data transmission signal comprising data received from the gNodeB. In some embodiments, the processing circuit is further configured to generate a transmission of the HARQ-ACK feedback message using the determined HARQ-PUCCH resource.

Abstract: An apparatus configured to be employed in a gNodeB associated with a new radio (NR) communication system that support resource sharing between NR physical downlink shared channel (PDSCH) and NR physical downlink control channel (PDCCH) is disclosed. The apparatus comprises a processing circuit configured to generate a PDSCH dynamic rate matching resource set configuration signal comprising information on one or more overlap resource sets, wherein each the one or more overlap resource sets comprises time-frequency resources on which any overlapping PDSCH may or may not be mapped, based on an indication provided within a PDSCH rate matching indicator signal. The apparatus further comprises a radio frequency (RF) interface, configured to provide the generated PDSCH dynamic rate matching resource set configuration signal, to an RF circuitry, in order to subsequently provide the PDSCH dynamic rate matching resource set configuration signal to a user equipment (UE), in order to enable the UE to identify the one or more overlap resource sets.

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.

Abstract: Embodiments of a User Equipment (UE) and methods for device-to-device (D2D) communication are generally described herein. In some embodiments, the UE may transmit a scheduling assignment (SA) control message that indicates time transmission intervals (TTIs) to be used for a D2D transmission of a data payload by the UE to a receiving UE during an SA cycle. The UE may transmit the data payload during the TTIs indicated in the SA control message. The TTIs used for the transmission of the data payload may be included in a group of D2D TTIs reserved for D2D transmissions. In some embodiments, a time resource pattern for transmission (T-RPT) may indicate a sequence of TTI indexes for the TTIs used for the transmission of the data payload.

Abstract: Embodiments may be directed to techniques to determine physical downlink control channel (PDCCH) candidates to assign to a user equipment (UE) based on one or more aggregation levels, each PDCCH candidate in a highest aggregation level of the one or more aggregation levels assigned by a random distribution over a whole control channel element (CCE) domain, and each PDCCH candidate in one or more non-highest aggregation levels of the one or more aggregation levels assigned a random distribution over one or more CCEs utilized by PDCCH candidates of the highest aggregation level. Embodiments also include selecting at least one of the PDCCH candidates to utilize to send downlink control information (DCI) to the UE, and causing transmission of the DCI to the UE via the PDCCH candidates selected.
