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: Technology for a user equipment (UE) operable to determine a transport block size (TBS) is disclosed. The UE can determine a number of assigned resource elements (REs) in one or more symbols for a transport block. The UE can determine a reference number of REs per physical resource block (PRB) in the transport block based on a reference number of REs for the transport block corresponding to each PRB and an assigned number of PRBs for the transport block. The UE can determine a TBS for the transport block based at least on the reference number of REs per PRB in the transport block. The UE can encode information in a selected transport block for transmission via a physical uplink shared channel (PUSCH) to a Next Generation NodeB (gNB) in accordance with the TBS determined at the UE.

Abstract: An apparatus of a user equipment (UE) comprises one or more baseband processors to process payload size comprising a number of feedback bits for a hybrid automatic repeat request-acknowledgement (HARQ-ACK) configuration received from a New Radio (NR) NodeB (gNB) for physical uplink shared channel (PUSCH) transmission without grant, and to determine a size of reserved resource elements (REs) and mapping pattern in accordance with the configured HARQ-ACK payload size, and to transmit uplink shared channel on PUSCH without grant which is rate-matched around the reserved REs. The UE alternatively comprises one or more baseband processors to process a downlink control information (DCI) grant received from a to schedule a PUSCH transmission, wherein the one or more baseband processors are configured for dynamic DCI grant overwriting to process a dynamic indication to interrupt the scheduled PUSCH transmission.

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: User equipment (UE) provides machine type communications (MTC) through a narrowband (NB)-long term evolution (LTE) system having a downlink transmission bandwidth in a range from about 180 kilohertz (kHz) to about 200 kHz. Receive circuitry is configured to receive, through a downlink transmission of an evolved node B (eNB) in the NB-LTE system, an NB-physical synchronization channel (NB-PSCH), the NB-PSCH including a synchronization signal and having a channel structure, the synchronization signal including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), and the channel structure defined by multiple subcarriers mutually spaced apart by about 15 kHz and located entirely within the downlink transmission bandwidth. Control circuitry configured to decode the synchronization signal.

Abstract: Some embodiments of this disclosure include apparatuses and methods for multiplexing uplink (UL) and/or downlink (DL) data transmission packets in user equipment (UE). In some embodiments, the UE may receive a resource configuration from a network node including one or more parameters for establishing a communication channel. The UE may receive a command from the network node indicating a UL grant for packet transmission from the UE. While preparing to transmit a first packet corresponding to the UL grant, the UE may receive a second packet having a higher priority designation, wherein the second packet includes an overlapping symbol with the first packet. The UE may transmit the second packet in view of this higher priority.
