    Abstract: Embodiments of a next generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. A gNB may be configurable to operate as a master gNB (MgNB). The MgNB may transmit radio-resource control (RRC) signaling to provide information for dual connectivity to allow the UE to utilize radio resources of both a master cell group (MCG) associated with the MgNB and a secondary cell group (SCG) associated with a secondary gNB (SgNB). The MgNB may transmit, to the SgNB, an SgNB release request message that indicates a partial suspension of the dual connectivity, wherein: a first portion of a configuration for the SCG is to be maintained and a second portion of the configuration for the SCG is to be released.

    Abstract: Apparatuses, systems, and methods for a handling uplink listen before talk (LBT) procedure failures in unlicensed bands of 5G NR. A wireless device may count a number of failed transmissions due to LBT procedure failures, e.g., that may occur in one or more transmit/receive occasions. The wireless device may determine that the count has met a threshold, e.g., that a number of failed transmissions has reached the threshold. The wireless device may initiate a recovery procedure based on determining that the count has met the threshold.

    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 and methods of increasing paging opportunities when the unlicensed band is used are described. The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PDSCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.

    Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to memory, where to configure the UE for communication of data in a New Radio-Unlicensed (NR-U) spectrum, the processing circuitry is to decode RRC signaling from a base station. The RRC signaling includes configuration information to configure a listen-before-talk (LBT) timer and a scheduling request (SR) prohibit timer. An LBT procedure is performed while the LBT timer is activated. An SR is encoded for transmission to the base station, based on detecting an unoccupied transmission resource within the NR-U spectrum during the LBT procedure. The SR transmission activates the SR prohibit timer. An uplink grant from the base station is decoded in response to the SR, the uplink grant received while the SR prohibit timer is activated. A buffer status report (BSR) is encoded for transmission to the base station based on the uplink grant.
