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.

An apparatus of a Radio Access Network (RAN) node, a system, and a method. The apparatus includes one or more processors to generate a conditional handover (CHO) execution message to a user equipment (UE), the CHO execution message including a plurality of execution conditions to trigger execution of a handover (HO) of the UE from the RAN node to a target RAN node; and causing transmission of the CHO execution message to the UE.

Embodiments of a generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may receive, from the UE, a first measurement report that indicates a first signal quality measurement based on new radio synchronization signals (NR-SS). The gNB may determine, based on reception of the first measurement report, a transmission direction for transmission of channel state information reference signals (CSI-RS) for a second RRM measurement at the UE based on the CSI-RS. The gNB may receive, from the UE, a second measurement report that indicates a second signal quality measurement based on the CSI-RS. The gNB may determine, based at least partly on the first and second signal quality measurements, whether to initiate a handover of the UE from a serving cell to a neighbor cell.

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.

Methods and arrangements for measurement gap configuration

Techniques to configure a user equipment (UE) for a multi-connectivity handover with a source base station (SBS) and a target base station (TBS) include encoding a measurement report for transmission to the SBS. The measurement report is triggered based on a measurement event configured by the SBS. Radio resource control (RRC) signaling from the SBS is decoded, the RRC signaling including a handover command in response to the measurement report. The handover command includes an indication for multi-connectivity support by the SBS and the TBS during the handover. A first protocol stack associated with the SBS and a second protocol stack associated with the TBS are configured at the UE. A packet data convergence protocol (PDCP) protocol data unit (PDU) received at the UE during the handover is processed using the first protocol stack or the second protocol stack.

The UE capability information indicates the UE supports the TDM-based multi-connectivity handover. A measurement report is encoded for transmission to the SBS, the measurement report triggered based on a measurement event configured by the SBS. RRC signaling from the SBS is decoded, which includes a handover command in response to the measurement report. The handover command indicates a TDM pattern for multi-connectivity with the SBS and the TBS during the handover. UL data is encoded for transmission to the SBS. Transmission of the UL data to the SBS is time-division multiplexed with communications between the UE and the TBS during the handover based on the TDM pattern.
