Abstract: A wireless device (14) transmits, to a radio network node (12), a radio resource control (RRC) connection request (18) that requests the establishment, re-establishment, or resumption of an RRC connection (16). The RRC connection request (18) indicates a type of core network to which the wireless device (14)selects to connect. The wireless device (14) in some embodiments receives a response to the RRC connection request (18), based on the type of core network to which the wireless device (14) selects to connect. For example, the wireless device (14) may receive the response using a protocol stack determined based on the type of core network to which the wireless device (14) selects to connect.

Abstract: According to an aspect, a user equipment, UE, in a suspended state in a Radio Access Network, RAN, in response to expiration of a first timer, transmits (1910) an RRCResumeRequest message. The UE receives (1920) a reject message in response to the RRCResumeRequest message. In response to the reject message, the UE starts (1930) a second timer and subsequently transmits (1940) a further RRCResumeRequest message. The further RRCResumeRequest message is received by the network during a period bounded approximately by the lesser of a duration of the second timer and a period of the periodic UE event and the greater of the duration of the second timer and the period of the periodic UE event.

Abstract: Systems, methods, and apparatus for handling communications relating to suspending a user equipment in a radio access network (RAN) are disclosed. An example method includes receiving, by a user equipment that is operating in a connected state, a radio resource control (RRC) release message. The user equipment determines, based on an indication in the RRC release message, whether to suspend the user equipment to an inactive state or an idle state, the indication comprising a presence or absence a suspend configuration field in the RRC release message. Responsive to determining that the indication is to suspend to an inactive state, the user equipment transitions to the inactive state.

Abstract: A method and wireless device for handling a periodic RNA update timer are disclosed. A method is implemented in a wireless device (WD) for stopping an update timer based on a condition including that the WD: receives an RRC Setup message triggering transition of the WD to an RRC_CONNECTED state in response to an RRC Resume request message; receives an RRC Suspend message indicating that the WD is to stay in an RRC_INACIVE state in response to an RRC Resume Request message; receives an RRC Release message triggering transition of the WD to an RRC_IDLE state in response to an RRC Resume Request message; fails to receive an RRC Resume message, RRC Suspend message or an RRC Release message after sending an RRC Resume Request message; or the WD enters the RRC_IDLE state from the RRC-INACTIVE state without transitioning through the RRC_CONNECTED state.

Abstract: According to an aspect, a wireless device enters an RRC inactive state from a RRC connected state, in response to a message received from the wireless network. The wireless device subsequently transitions from the RRC inactive state to the RRC connected state and resumes one or more measurements according to one or more measurement configurations stored while the wireless device was in the RRC inactive state.

Abstract: A method for enabling operations for a relay node comprises receiving, at a first network node, a system information block including a first indication and a second indication, wherein the first indication indicates that a first cell is a non-standalone cell and is barred for standalone user equipments (UEs), and the second indication indicates that the first network node is able to access the first cell. The method further comprises identifying, at the first network node, whether the first network node is able to access the first cell based on the second indication in the system information block. The method may improve a performance in the network by enabling a relay node to operate in a non-standalone cell, such that both access and backhaul in E-UTRAN New Radio Dual Connectivity (EN-DC) are supported.

Abstract: A central unit (300A) and a first distributed unit (300B) of a first network node (300) and methods therein, for handling a communication with a wireless device (302) in a wireless network. The central unit (300A) sends an indication to the first distributed unit (300B) to indicate whether a current procedure for the wireless device is an inter-central unit procedure or an intra-central unit procedure. The first distributed unit (300B) is thereby able to decide whether to send information about the communication to the central unit via a user plane or via a control plane, based on a reduced amount of signalling including the indication.

Abstract: A wireless device (600, 700), a network node (800, 900) and a respective method performed thereby for performing measurements for fast setup are provided. The method (300) performed by the wireless device (130) comprises receiving (310), during a RACH procedure, a "message 4" (Msg 4), which Msg 4 may be a contention resolution, the Msg 4 comprising a trigger for performing a fast measurement. The method (300) also comprises performing (320) a fast measurement on one or more carrier(s) that the wireless device (130) receives. The method (300) may further comprise sending (330) a measurement report to the network node (111) which sent the Msg 4 to the wireless device (130).

Abstract: According to one exemplary embodiment of inventive concepts, a UE that operates in a RAN may be configured to receive (1300) new radio, NR, radio resource control, RRC, messages from a secondary network node. The NR RRC messages may each contain a number that the secondary network node added to the NR RRC messages to indicate their respective order in a sequence which the NR RRC messages were sent by the secondary network node. The NR RRC messages may each contain parameters that the UE uses to configure its communications through a NR interface with the secondary network node. The UE may send (1302) NR RRC complete messages toward the secondary network node responsive to receipt of the NR RRC messages, wherein the NR RRC complete messages each contain an indication of the NR RRC message that was received. The UE may control (1304) the sending of the NR RRC complete messages to indicate to the secondary network node whether the NR RRC messages are received in an order that is the same as the sequence.

Abstract: According to an exemplary embodiment a method may be provided to operate a central unit, CN, node that is coupled with first and second distributed unit, DU, nodes. Communication is provided (1501) between the CU node and a mobile communication device through the first DU node over a first radio link between the first DU node and the mobile communication device. A message is received (1503) at the CU node from the first DU node informing the CU node that the radio link is temporarily unavailable. Responsive to receiving the message, communication between the CU node and the mobile communication device through the first DU node is suspended (1505), wherein configuration of the first DU node to serve the mobile communication device using the first radio link is maintained while suspending communication between the CU node and the mobile communication device through the first DU node. While suspending communication between the CU node and the mobile communication device through the first DU node, communication may be provided (1507) between the CU node and the mobile communication device through the second DU node over a second radio link between the second DU node and the mobile communication device.
