Abstract: A user equipment (UE) may assess a radio link quality of a plurality of frames for communication, via the interface to the RF circuitry, with a radio access network (RAN) node. When the radio link quality of a frame, of the plurality of frames, is below an out-of-sync (OOS) threshold, the UE may indicate that the frame is OOS. When the radio link quality of a frame, of the plurality of frames, is above an in-sync (IS) threshold that the frame is IS. Additionally, or alternatively, the UE may process information, received from the RAN node indicating a partial subframe, of a subframe, to be used to transmit uplink control information (UCI) to the RAN node. The UE may also perform UCI mapping for using of the partial subframe to transmit UCI via a physical uplink control channel (PUSCH), and proceed by using the partial subframe to communicate the UCI to the RAN node.

Abstract: Aspects of filtering coefficient configuration operations are described. Some aspects include a user equipment (UE) decoding a measurement configuration information element (IE) including a measurement quantity parameter, a reference signal (RS)-type filter configuration and at least one filter coefficient. In some aspects, the UE filters at least one of a cell measurement result and a beam measurement result, according to the measurement configuration IE. If the measurement quantity parameter indicates the cell measurement quantity, the UE can filter the cell measurement result according to the RS type filter configuration and the filter coefficient to determine a measurement evaluation input for a measurement reporting operation. If the measurement quantity parameter indicates the beam measurement quantity, the UE can filter the beam measurement result according to the RS type filter configuration and the filter coefficient to determine a beam measurement selection input for a beam measurement selection operation.

Abstract: An embodiment for user equipment that receives a plurality of measurement gap repetition patterns from a network. Each measurement gap repetition pattern may be assigned to a different frequency of the network. The plurality of measurement gap repetition patterns may include skipping measurement patterns. Further embodiments may include the user equipment receiving a repetition period in a measurement object frame or receiving a plurality of measurement gap repetition patterns in which the measurement gaps are non-colliding with measurement gaps of other repetition patterns assigned to the user equipment.

Abstract: Embodiments of a generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. A source gNB may operate as a master gNB (MgNB) before a handover. A target gNB may operate as a secondary gNB (SgNB) before the handover. The target gNB may operate as the MgNB after the handover. The target gNB may, as part of operation as the SgNB, transmit a first data packet received from the source gNB for relay to the UE. The target gNB may, as part of operation as the MgNB, transmit, a second data packet received from a serving gateway (SGW) for relay to the UE.

Abstract: Logic may receive an initial communication from a user device, the initial communication comprising capabilities. Logic may determine, based on an indication of a capability to support new radio frequency layers from the capabilities for the user device, a measurement gap configuration for the new radio frequency layers and a measurement gap configuration for a channel state information reference signal. Logic may send a frame with a preamble to a physical layer comprising the measurement gap configuration. Logic may send an initial communication to a physical layer, wherein the initial communication comprises capabilities for a user device. Logic may decode downlink data with a measurement gap configuration. And logic may parse the measurement gap configuration to determine at least one measurement gap identification and at least one offset for the new radio frequency layers and a channel state information reference signal.

Abstract: Systems and methods provide flow control for uplink traffic in an integrated access and backhaul network. A first relay node determines that its uplink buffer has reached an occupancy level higher than a pre-determined level. In response, the first relay node transmits, to a second relay node associated with the first relay node, a message indicating a buffer occupancy status of the uplink buffer of the first relay node.

Abstract: An apparatus of a base station (BS) of a radio access network (RAN) comprises memory and processing circuitry. The processing circuitry includes a central unit (CU) portion and a distributed unit (DUI) portion that implement a BS multi-layer protocol stack divided between the CU portion and the DU portion. The processing circuitry initiates a handover to change a serving cell of user equipment (UE). The handover includes a change in a portion of logical layers of the BS multi-layer protocol stack, and the processing circuitry encodes an information element for transmission to the UE indicating logical layers of a UE multi-layer protocol stack implemented in the UE to be reset by the UE in association with the handover.

Abstract: Briefly, in accordance with one or more embodiments, a user equipment (UE) may enter into an E-UTRAN Routing Area Paging Channel state, and is configured with an E-UTRAN Routing Area and an Anchor identifier to identify an anchor evolved Node B (eNB) for the UE. The UE selects to a new cell without performing a handover procedure, and performs a cell update procedure. The UE also may enter into a Cell Update Connected state, and is configured with an Anchor identifier. The UE selects to a new cell, performs a cell update procedure, performs a buffer request procedure, and performs a cell update procedure to download buffered data and to perform data transmission with the new cell.
