Abstract: The present application relates to user equipment (UE) aggregation. For instance, a UE aggregation group is defined based on a subscription of multiple UEs with a network. Configuration information identifying the UE aggregation group, its member UEs, the role of each UE (e.g., whether a group leader or, otherwise, a group member), and/or radio access capability signaling (RACS) is stored. Upon a registration of a UE, the UE aggregation group is indicated to the network. The network then enables an aggregated communication capability to the UEs of the UE aggregation group based on the configuration information.

Abstract: Systems and methods of providing feedback when a specific PDU is successfully delivered or transmitted are described. The node hosting PDCP entity indicates triggering of a DDDS frame from the remote corresponding node. Rather than immediately triggering transmission of a DDDS frame, the node hosting PDCP entity indicates triggering based on successful delivery of a PDU having a specific SN, as long as in-sequence delivery or transmission of PDUs up to the specific SN was successful. The DDDS frame is transmitted once the corresponding node determines that the PDU having the SN was successfully delivered or transmitted. After reporting by the DDDS frame, the QoS flow associated with the PDUs is remapped from a source DRB to a target DRB.

Abstract: Methods, systems, apparatuses, and computer programs for enhancing UE handover. In one aspect, the method can include obtaining a request for a handover event from a UE, wherein the request includes at least (i) a request for access to a primary cell group and (ii) data indicating capabilities of the UE, determining, based on the UE capabilities, that the UE is capable of maintaining communication with a secondary cell group of a base station during handover of the UE to the primary cell group of the first base station, generating based on the determined UE capability, a handover command that instructs the UE to maintain communication with the secondary cell group of the base station during handover of the UE to the primary cell group, encoding the generated handover command for transmission to the UE, and transmitting the generated handover command to the UE.

Abstract: Embodiments of a Next Generation Node B (gNB) are described herein. The gNB may be configured with logical nodes, including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may include a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. The gNB may initiate an El interface setup procedure, a bearer context setup procedure, and a UE context setup procedure to establish a UE context that includes a signaling radio bearer (SRB) and a data radio bearer (DRB) configuration. The UE context setup request message may be configured to include quality-of-service parameters for the DRB configuration.

Abstract: An apparatus of a next generation NodeB (gNB) comprises one or more baseband processors to interconnect a gNB Central Unit control-plane entity (gNB-CU-CP) with a gNB Central Unit user-plane entity (gNB-CU-UP) via an E1 control plane interface and a gNB Distributed Unit (gNB-DU) via an F1 control plane interface. Rather than relying on multiple class-1 procedures initiated by gNB-CU-CP toward gNB-CU-UP and gNB-DU, the one or more baseband processors are configured to establish or modify a bearer context and to communicate data transport tunneling and/or packet data convergence protocol (PDCP) preservation status information for a specific user equipment (UE), utilizing the direct F1 user plane interface between gNB-DU and gNB-CU-UP to avoid relaying delay. The gNB can include a memory to store the bearer context and data transport tunneling information.

Abstract: A UE may perform a location-based conditional handover (CHO) based on a region information and size parameter associated with a serving cell of a non-terrestrial network (NTN). In time-based CHO, the UE may perform CHO in response to expiration of a network-configured wait time. Alternatively, the UE may perform CHO by randomly selecting a wait time from a network configured time range. The selection may be randomized using a network provided seed or using a cell Radio Network Temporary Identifier (RNTI) value. In elevation-based CHO, the UE may perform CHO in response to the elevation angle of a satellite being less than a network configured threshold. When the UE is configured with multiple cells of the NTN, and the CHO criteria for two or more of the cells are satisfied, the UE may select a target cell for CHO based on network indicated prioritization of the cells.

Abstract: Systems and methods of setting up an E1 interface for a gNB are described, A transmitting entity of the gNB-CU-CP and gNB-CU-UP initiates the first TNL association between the gNB-CU-CP and gNB-CU-UP, and is also limited to initiating the E1 Setup procedure. The transmitting entity sends an E1 SETUP REQUEST message to set up the E1 interface. Afterwards, a message is received from the receiving entity. The transmitting entity determines that the setup of the E1 interface is successful if the message contains IEs of an E1 SETUP RESPONSE message. The types of IEs include a message type IE and a name of the transmitting entity.

Abstract: Apparatuses, systems, methods, and computer-readable media associated with F1 interface arrangement configuration within a network that implements virtualized NodeBs are disclosed herein. In embodiments, one or more non-transitory computer-readable media having instructions stored thereon, wherein the instructions, in response to execution by one or more processors, cause a centralized unit (CU) of an access node to generate a CU configuration update message, the CU configuration update message to include an indication of a transport network layer (TNL) address of the CU for which a TNL association between the CU and a distributed unit (DU) of the access node is to be added or removed, and cause the CU configuration update message to be transmitted to the DU. Other embodiments may be described and/or claimed.
