Abstract: A user equipment (UE) in idle mode may use a preconfigured uplink resource for transmission, retransmission, and/or hybrid automatic repeat request (HARQ). For example, the UE may store configuration data for a preconfigured uplink resource and a radio network temporary identifier (RNTI) for idle mode communication. In idle mode, the UE generates an uplink transmission using the preconfigured uplink resource. After the uplink transmission, the UE starts a retransmission timer, and monitors physical downlink control channel (PDCCH) with the RNTI provided in the configuration data for HARQ acknowledgement/negative acknowledgement (ACK/NACK).

Abstract: Technology for a user equipment (UE), operable for monitoring a physical downlink control channel (PDCCH) is disclosed. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein the predetermined monitoring occasion has a periodicity of P slots or P symbols with an offset Os. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Os has an offset with respect to a first slot in subframe number zero (SFN #0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

Abstract: 5G methods and architectures to determine active SCells and their bandwidth parts (BWP) used in carrier aggregation (CA) are disclosed in which activating a BWP for an active SCell is performed initially according to a default value provided in initial radio resource control (RRC) messaging. After initialization, SCells and the SCell BWPs used by the user equipment (UE) are activated by RRC messaging, downlink control information (DCI) or dedicated medium access control (MAC) control elements (MAC CEs) with the initial BWP used for an activated SCell being a default value provided during initialization.

Abstract: Methods, systems, apparatus, and computer programs, for warning system notifications and acquisition. In one aspect, the method includes actions of receiving, by user equipment (UE) and from an access node, data indicating the presence of a PDSCH broadcast, configuring, by the UE and based on the received data, a narrowband (NB) to receive transport blocks in PDSCH, and receiving, by the UE, one or more transport blocks broadcast in PDSCH using the NB, the one or more transport blocks including the warning system information.

Abstract: A Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB is configurable to operate as a source gNB. The gNB is configured with logical nodes including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU comprises a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. When a handover of a User Equipment (UE) from the source gNB to a target gNB is performed, the gNB transfers, from the gNB-DU to the gNB-CU-UP, a downlink data delivery status (DDDS) message to indicate that the gNB-CU-UP is to stop transfer, to the gNB-DU, of downlink data intended for the UE.

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.

Abstract: Systems and methods of a security framework for an RRC connection are described. The UE receives a release message that comprises a current Next Hop Chaining Counter (NCC). The UE derives a new KeNB* using the current NCC and transmits an EDT RA preamble to same or a different base station. After receiving an RAR with an uplink allocation, the UE transmits a RRCConnectionResumeRequest message. The UE transmits uplink data encrypted using KeNB* if the uplink allocation includes a data allocation sufficient for the data, fall backs to a legacy RRC connection procedure in which the stored KeNB* is discarded and then KeNB* is re-derived if the data allocation is insufficient for the data due to a CE level change, and fall backs to a legacy RRC connection procedure in which the stored KeNB* is used instead of discarding KeNB* if the uplink allocation excludes the data allocation.

Abstract: Systems, methods, and apparatuses can provide or obtain scheduling information for a system information block type1-bandwidth reduced (SIB1-BR) without obtaining a master information block during handover. A user equipment (UE) can identify SIB1-BR scheduling information in a radio resource control connection (RRC) reconfiguration message. The UE can determine scheduling of an SIB1-BR for a target cell based on the RRC reconfiguration message, and process the SIB1-BR received from the target cell during the determined scheduling.
