There is provided an apparatus, comprising means for performing: receiving a first message, the first message indicating information for at least one network slice identity in one or more radio network areas; receiving a second message, the second message indicating configuration information for one or more network slices; determining a configuration to be used for a given network slice based on the first and second messages.

Configuration indication

A method for a transfer of a UE context within a secondary network from a source secondary network node to a target secondary network node. The UE is served by a master network node and the source secondary network node. The method includes the following steps performed by the UE: receiving a first message indicative of a secondary network node measurement configuration; based on the measurement configuration, performing measurements of potential candidates for a target secondary network node; and sending a second message comprising a measurement report indicative of the measurements of potential candidates for a target secondary node.

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for transferring traffic in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first Central Unit-Control Plane (CU-CP) of a first IAB donor transmits, to a second CU-CP of a second IAB donor, a request to transfer target traffic via a Distributed Unit (DU) of the second IAB donor. The request comprises first information of the target traffic. The first CU-CP receives, from the second CU-CP, second information to be used for configuring the target traffic. This solution can improve the reliability and robustness of the IAB communication.

A Master Node (MN)and a method therein for handling of a Secondary Cell Group (SCG) for a UEoperable in a dual connectivity mode with the MN and a Secondary Node (SN)operating in a network. A Master Cell Group (MCG) is 5 associated with the MN and the SCG is associated with the SN. The MN decides to perform a first operation relating to a suspension or a resumption of the SCG independently from a second operation relating to a suspension or a resumption of the MCG. The MN transmits, to the UE, an indication indicating the first operation and indicating the second operation. Further, the MN transmits, to the SN, an indicationindicating the first operation relating to the suspension or the resumption of the SCG.

In some embodiments, a method performed by a wireless device in a cellular communications system comprises transmitting measurements with a first message to a network node. The first message is a request to resume a connection of the wireless device with a target cell, and the measurements are measurements performed by the wireless device while in a dormant state. Corresponding embodiments of a wireless device are also disclosed. Embodiments of a method of operation of a wireless device for reception of a request for early measurements in association with a paging message and corresponding embodiments of a wireless device are also disclosed. Embodiments of methods of operation of a network node and corresponding embodiments of a network node are also disclosed.

A wireless device operates with dual connectivity to a Master node and a Secondary node, which are both New Radio, NR, nodes. It receives measurement and/or reporting configuration information from a network. It determines whether the received 5 configuration information relates to a MCG or a SCG. Specifically, it is determined that the received configuration information relates to the MCG if the configuration information is received directly within an RRCReconfiguration message received via SRB1, or that the received configuration information relates to the SCG if the configuration information is received directly within an RRCReconfiguration messagereceived via SRB3, or alternatively if the configuration information is received in an RRCReconfiguration message that is embedded within an RRCReconfiguration message received via SRB1.

A method performed by a User Equipment, UE, for handling a Secondary Cell Group, SCG, configuration in a wireless communications network is provided. The UE receives () from a network node, an SCG configuration and a trigger condition related to the signal quality of a cell associated with the SCG configuration. The UE then performs () signal quality measurements of a cell associated with the SCG configuration. When the trigger condition of the cell is fulfilled according to the received SCG configuration, the UE applies () the SCG configuration associated to the cell fulfilling the trigger condition.

Handling a secondary cell group configuration

According to an aspect, one or more network nodes of a wireless communication system sends, to a wireless device operating in the wireless communication system, mobility reference signal (MRS) configuration information, the MRS configuration information specifying one or more parameters for each of a plurality of MRS configurations. The network node subsequently sends, to the wireless device, an activation command indicating that at least a first one of the MRS configurations is to be used by the wireless device, the activation command including an index identifying the first one of the MRS configurations from among the plurality of MRS configurations. The wireless device receives the MRS configuration information and the activation command.
