Abstract: Methods and systems are provided to indicate assistance information for radio access technologies to support interface selection for New Radio (NR) Vehicle-to-Everything (V2X) processes. An upper layer entity exchanges information with lower layer entity while the upper layer can continue to use the existing interface for V2X transmission until it is not able to use the current interface. The upper layer can be a V2X layer and the lower layer can be an Access Stratum (AS) layer. The upper layer can request availability information from the lower layer for other applicable interfaces. The upper layer then instructs the lower layer to provide assistance information for one or more applicable interface(s), depending on whether mapped to the ongoing service. In providing availability information, the lower layer can continuously measure criteria, such as channel conditions, to determine the availability of relevant interfaces and indicate the availability information to the upper layer.

Abstract: Methods and apparatus are described for carrying out timing adjustments in a wireless communications network. The approach includes a user equipment (UE) that includes processor circuitry and a radio front end circuitry. The processor circuitry is configured to obtain a timing advance value for the wireless communication with a satellite base station, and to determine a transmission time for transmission of a random access channel (RACH) preamble based on the timing advance value. The radio front end circuitry transmits the random access preamble at the transmission time. Finally, the processor circuitry is further configured to receive a response to the transmitted random access preamble.

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.

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: Systems and methods of providing UE capability are described. A capability ID is associated with the same Radio Capability information for multiple UEs. If the capability ID is validated at a network node, the UE provides the capability ID to a RAN node, which obtains the capability information from the network node after providing the received capability ID to the RAN node. The capability ID is received in an RRC Setup Complete, Security Mode Complete or Reconfiguration Complete message. The network node, if the Radio Capability information is not available, requests and receives the Radio Capability information and associates it with the capability ID, and marks that the capability ID as not validated until a threshold number of the UEs have provided the same Radio Capability information. The capability ID is based on a UE device type, manufacturer and software version.

Abstract: Technology for dual connectivity is disclosed. A user equipment (UE) can identify a first physical channel that includes a first uplink control information (UCI) and a second physical channel that includes a second UCI. The UE can select a priority level for the first physical channel and a priority level for the second physical channel. The UE can apply power scaling to a first physical channel transmission or a second physical channel transmission if a total transmit power of the UE would exceed a specific value during a period of time. The UE can scale a transmit power for the second physical channel if the priority level for the first physical channel is higher than the priority level for the second physical channel depending on a type of first UCI and a type of second UCI.

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.
