Abstract: A method includes receiving (610), by a user device that has been configured for dual connectivity, preconfiguration information including information indicating a signaling radio bearer for a second network node to enable the user device to report failure of a first random access procedure between the user device and a first network node, via a second random access procedure with the second network node regardless of whether a connection has been established between the user device and the first network node: transmitting (640), by the user device to the second network node via the indicated signaling radio bearer, a radio link failure report indicating a failure of the first random access procedure with the first network node; and receiving (650) a message indicating an action to be performed by the user device in response to the failure of the first random access procedure.

Abstract: Techniques are provided for enabling user equipment (UE) context retrieval in radio resource control RRC inactive status with a shared radio access network (RAN) database (DB) within a distributed database architecture. A version indicator in an inactive Radio Network Temporary Identifier (I-RNTI) is populated by the UE to indicate one or more I-RNTI versions, defined herein, and indicates the type of data in the remainder of the I-RNTI used for communicating the location of a RAN DB that stores the UE context, to a target network node. The target network node then uses the data in the I-RNTI, further dependent on the I-RNTI version, to retrieve the UE content from the RAN database. Certain embodiments utilize a RAN DB Area (RDBA) and/or RAN DB Set Area (RDSA), and certain embodiments utilize a network node set ID.

Abstract: A method includes receiving via a serving cell that is associated with a first distributed unit of the network node, a list of conflicting physical cell identities and a request to provide an indication of whether a measured cell is intra-distributed unit or inter-distributed unit with respect to the serving cell; determining a physical cell group identifier of the serving cell; determining, by the user equipment, a physical cell group identifier of the measured cell; comparing the physical cell group identifier of the measured cell to the physical cell group identifier of the serving cell, to determine whether: the measured cell is intra-distributed unit with respect to the serving cell, or the measured cell is inter-distributed unit with respect to the serving cell; and sending a layer 1 measurement report including information indicating whether the measured cell is intra-distributed unit or inter-distributed unit with respect to the serving cell.

Abstract: Disclosed is a method for interference coordination for mobility. A first apparatus receives, from a second apparatus, a first interference coordination pattern of the second apparatus. The first apparatus transmits, to the second apparatus, a first handover request for handing over a first terminal device from the first apparatus to the second apparatus. The first apparatus receives, from the second apparatus, a first handover request acknowledgement comprising at least a first handover command. The first apparatus transmits, to the first terminal device, the first handover command based at least partly on the first interference coordination pattern of the second apparatus.
