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.

Flow control for uplink traffic in an integrated access and backhaul network

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.

UE capability transfer and storage

A master node (MN) that determines a manner of a protocol data unit (PDU) session to be served, wherein the manner of the PDU session includes a split PDU session between the MN and a secondary node (SN) or a whole PDU session served by the MN, generates a request message to be transmitted to the SN to setup PDU session resources on the SN based on the manner of the PDU session is to be served and indicates, to the SN, the manner of the PDU session to be served. A SN that receives, from a MN, a request message to setup PDU session resources, determines a manner of the PDU session to be served, and sets up the PDU session resources on the SN, based on at least the manner of the PDU session to be served.

Split protocol data unit (PDU) session indication for multi-rat dual connectivity (MR-DC) with 5GC

A computer-readable storage medium stores instructions for execution by one or more processors of a UE. The instructions configure the UE for small data transmission (SDT) in a 5G NR network and cause the UE to perform operations comprising detecting while in an RRC_Inactive state, a radio link failure during a first SDT of UL data to a base station. A secure key for a second SDT is generated based on the radio link failure. A configuration message including an indication of the second SDT is transmitted to the base station. A response message including a UL grant is received from the base station. The UL data is encoded for the second SDT using the secure key. The second SDT is performed using the UL grant while the UE is in the RRC_Inactive state.

Small data transmission (SDT) procedures and failure recovery during an inactive state

Disclosed are systems, apparatuses, methods, and computer-readable media for use in a wireless network for facilitating radio access synchronization. The method includes receiving, from a user equipment (UE) a message having a media access control (MAC) control element (CE) format and comprising a MAC protocol data unit (PDU) structure, the message being formed by multiplexing one or more MAC service data units (SDUs). The method further includes generating a response message to the received message by multiplexing a MAC random access response (RAR) with one or more MAC SDUs. The method then transmits the response message to the UE.

Apparatus and method for generating mac format for messaging in a two-step random access procedure

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.

Generation node-B (GNB), user equipment (UE) and methods for handover in new radio (NR) systems

Some demonstrative embodiments include devices, systems and/or methods of communication over common control channels. For example, an apparatus may include logic and circuitry configured to cause a User Equipment (UE) to determine a selected Common Control Channel (CCCH) message configuration from a first predefined message configuration and a second predefined message configuration, the first predefined message configuration having a first predefined message bit-size, the second predefined message configuration having a second predefined message bit-size; to generate an Uplink (UL) CCCH message according to the selected CCCH message configuration, the UL CCCH message comprising a Medium Access Control (MAC) header comprising a Logical Channel Identify (ID) (LCID) field having a value corresponding to the selected CCCH message configuration; and to transmit the UL CCCH message to a Next Generation Node B (gNB) over a logical channel corresponding to the selected CCCH message configuration.

Apparatus, system and method of communication over common control channels

This disclosure describes systems, methods, and devices related to service function chaining in wireless networks. A communications system may include a communication control function to select one or multiple communication service functions associated with establishing service function chaining (SFC) services for telecommunications; a service orchestration and chaining function (SOCF) to establish the SFC services; and a service orchestration exposure function (SOEF) to expose the SFC services to an application function (AF) of the system.

Enhanced service function chaining in next generation cellular networks

The present disclosure relates to selecting a Local Management Function (LMF) in a wireless communication network, a next generation Radio Access Network (NG-RAN) acquires a capability from a user equipment (UE), the capability indicating whether the UE is capable of supporting LMF in Radio Access Network (RAN). An access and mobility management function (AMF) is then notified whether the UE is capable of supporting LMF in RAN. An LMF selection is then received from the AMF. Then a response is transmitted to the UE based on the received LMF selection, the response indicating whether a positioning procedure to be carried out by the UE is based on LMF in RAN. In this manner, the capabilities of the UE are taken into consideration when selecting an LMF for a positioning procedure.

Apparatus and method for support of location management functionality in a radio access network

Various embodiments herein provide techniques for integrated access and backhaul (IAB) nodes. For example, embodiments include techniques associated with: rate-proportional routing for network coding; utilizing multiple routes in IAB networks; user equipment (UE) and parent selection for efficient topology in IAB networks; establishing efficient IAB topologies; and/or adaptive coded-forwarding for network coding. Other embodiments may be described and claimed.

Techniques for integrated access and backhaul (IAB) nodes

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.

Apparatus of GNB to enable an inactive mode in dual connectivity

Methods, systems, and storage media are described for command handling for simultaneous connectivity handovers. Other embodiments may be described and/or claimed.

Command handling for simultaneous connectivity handoffs

A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a one-step paging reception or a two-step paging reception based on being in a sub-state of an idle mode. A UE can enter into an idle state to enable a decreased power consumption of battery, and further reduce power consumption by only monitoring a PDCCH in response to operating in a camped on any cell state, and eliminate processing a paging message when in the camped on any cell state.

Paging reception for user equipment in idle and inactive state

In an example method, a user equipment (UE) determines a first identifier assigned to the UE for use on a first wireless communications network and one or more first time slots for monitoring the first wireless communication networks. The UE determines a second identifier assigned to the UE for use on a second wireless communications network and one or more second time slots for monitoring the second wireless communication networks. The UE determines that the one or more first time slots at least partially overlap the one or more second time slots, and in response, transmits to the second wireless communications network, a request for a third identifier to be assigned to the UE for use on the second wireless communications network and/or a request that the one or more second time slots be offset by an interval of time.

Avoiding paging collisions in a device with multiple subscriptions

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.
