Abstract: An apparatus of a source Radio Access Network (RAN) node, a system, and a method. The apparatus includes one or more processors that configures a user equipment (UE) for a conditional handover of the UE from the source RAN node to a candidate target RAN node based on at least one of a first configuration of the source RAN node or conditions to be met for execution of the conditional handover; and in response to a reconfiguration of the source RAN node to a second configuration, configure the UE for the conditional handover to the candidate target RAN node based on the second configuration by causing transmission of a message to the UE including information based on the second configuration.

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: A UE may decode a radio-resource control (RRC) reconfiguration message comprising a conditional handover (CHO) configuration (CHO-Config) which may identify a CHO configuration for at least one target candidate cell. The CHO configuration may include two or more CHO triggering events for an entry condition. The UE may monitor measurement quantities of the target candidate cell for the entry condition to determine if any of the CHO triggering events are met, start a first count-down timer when the entry condition of a first of the CHO triggering events is met and start a second count-down timer when the entry condition of a second of the CHO triggering events is met. The UE may apply the CHO configuration to the target candidate cell when both of the two CHO triggering events remain fulfilled upon expiration of the both timers.

Abstract: Technology is disclosed for an evolved node B (eNB) operable for early data transmission (EDT) in a user plane (UP) in a cellular internet of things (CIoT) evolved 5 packet system (EPS) network. The eNB can be configured to encode, at the eNB for transmission to a user equipment (UE), a message 4 (Msg4) including a resume identifier (ID) and a next-hop chaining count (NCC). The eNB can be configured to determine, at the eNB, a delivery status of the Msg4 to the UE. The eNB can be configured to encode, at the eNB for transmission to a previous eNB of the UE, one or more of an EDT failure 10 indicator or the resume ID.

Abstract: A User Equipment (UE) and a Radio Access Network (RAN) node may be configured to use multiple Scheduling Request (SR) configurations. A SR configuration may indicate to radio resources to be used to communicate a SR to the RAN node. The RAN node may provide UE with information associating logical channels to SR configurations. When the UE has data to transmit to the RAN node, the UE may determine the logical channel corresponding to the data, determine the SR configuration corresponding to the logical channel, and communicate a SR to the RAN node in accordance with the SR configuration. Upon receiving the SR, the RAN node determine the SR configuration used to transmit the SR and in turn determine the logical channel for which the SR was transmitted. The RAN node may then transmit an Uplink (UL) grant for the logical channel to 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.
