    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 of reducing control plane latency in a 5G IAB network are described. SRs transmitted between nodes indicate that a control plane PDU is to be transmitted. The SRs use periodic resources or OCCs reserved for control plane signaling and are initiated by an RRC message or RACH from the UE. The SRs are initiated if the LCID field in the MAC subheader of the RRC message indicates the CCCH or the DCCH logical channel. If the PDU is available after the original resource, a resource is used that is provided via another grant, which is periodically provided or automatically initiated due to failure to transmit on the original grant. The SR or RRC message can also specify a delayed timeslot for the grant. For contention-based procedures the RACH preamble is randomly selected or selected from among a set of RACH preambles assigned for RRC procedures.

    Abstract: There is are provided methods and apparatus relating to layer 2 relaying and mobility using a sidelink interface, including a remote user equipment (UE) for use in a wireless communication network, the UE comprising: a device to network (D2N) entity, a device to device (D2D) entity, and control logic to: receive a service data unit derived from an IP packet direct the service data unit to the D2N entity for communication with an eNB using a Uu interface in a first mode of operation, and direct the service data unit to the D2D entity for communication with the eNB via a first relay UE using a sidelink interface in a second, relay, mode of operation.

    Abstract: Apparatuses of wireless communication devices are disclosed. An apparatus of a user equipment includes one or more processors configured to start a first timer responsive to detection of a Radio Link (RL) failure, start a second timer and trigger a beam recovery procedure one or more times responsive to expiry of the first timer if RL recovery is not detected, and start a third timer and attempt to find a suitable cell for Radio Resource Control (RRC) connection reestablishment responsive to one or more expiries of the second timer if RL recovery fails. The one or more processors are also configured to go to an RRC idle or inactive state responsive to expiry of the third timer if a suitable cell for RRC connection reestablishment is not found.
