Abstract: Embodiments include methods for a first node configured for dual connectivity with a user equipment (UE) together with a second node of a wireless network. One of the first and second nodes provides a secondary cell group (SCG) for the UE. Each of the first and second nodes includes a first unit that is one of a centralized unit (CU) and a distributed unit (DU) and a second unit that is the other of the CU and the DU. Such methods include the first unit of the first node receiving an indication of change in activation status of the SCG, and sending the indication to the second unit of the first node or to the first unit of the second node. The change in activation status is from SCG activated to SCG deactivated or vice versa. Other embodiments include first unit and first node apparatus configured to perform such methods.

Abstract: Embodiments include methods for a user equipment (UE) configured to communicate with a radio access network (RAN) via a master cell group (MCG) and a secondary cell group (SCG). Such methods include transmitting, to a RAN node configured to provide the MCG, a first message indicating an initial beam failure detected in the SCG based on a first beam failure detection (BFD) configuration and while the SCG is deactivated. Such methods include detecting one or more subsequent beam failures in the deactivated SCG after the initial beam failure and selectively transmitting to the RAN respective second messages indicating the one or more subsequent beam failures. Each second message is selectively transmitted based on one or more of the following: whether the UE has received a second BFD configuration from the RAN node configured to provide the MCG, and whether a message transmission timer is running, is stopped, or has expired.

Abstract: Techniques for inter base station handovers are provided for the case where a wireless device is operating in a PDCP packet duplication mode. The handover techniques enable the wireless device to transition from PDCP packet duplication with the source cell to DAPS and to transition back to PDCP packet duplication with the target cell when the handover is complete. In some embodiments, the RLC entities established with the source cell are preserved during the inter base station handover. The handover techniques ensure that QoS requirements for URLLC can be met during the inter base station handover.

Abstract: Methods are described for a wireless device, such as a UE, to execute a Layer-1 (LI) or Layer-2 (L2) based inter-cell mobility serving cell change, based on the fulfillment of an execution condition (e.g., based on measurements), using a conditional reconfiguration. The UE receives, from a serving network node, a message containing at least one conditional reconfiguration for L1/L2 based inter-cell mobility serving cell change. The at least one conditional reconfiguration includes at least one of an execution condition, an indication of a candidate target cell for L1/L2 mobility, and a lower layer command. When an execution condition associated to the candidate target cell for L1/L2 inter-cell mobility is fulfilled, the UE executes the conditional reconfiguration that results in a L1/L2 based inter-cell mobility serving cell change to the candidate target cell. The UE then starts to operate according to a configuration of the candidate target cell in the L1/L2 based inter-cell mobility serving cell change.

Abstract: A network node (1300) configures an activation status of a conditional reconfiguration within a User Equipment, UE (110) connected to a network via Dual Connectivity (DC) or Multi-Connectivity (MC). The activation status supports an activated state and a deactivated state. The conditional reconfiguration defines a reconfiguration of the UE (110) that is to be performed in response to a set of one or more conditions being fulfilled. The UE (110) deactivates the conditional reconfiguration in response to an event. The CE (110) refrains from performing the reconfiguration when the set of conditions is fulfilled while the conditional reconfiguration is deactivated.
