Hierarchical network operation and resource control system and method for a mega satellite constellation, belonging to the field of spatial information technology, are provided. The hierarchical network operation and resource control system includes a service layer, a global organization layer, a local coordination layer and a resource layer. The service layer is used as an input to drive operation of whole system. The global organization layer is to realize “operation, measurement and control” integrated control and decision of whole network. The local coordination layer is to realize local management decision and management slice generation. The resource layer is to provide physical resource and physical device and realize resource virtualization. By deploying local coordination layer controllers on GSO or MEO satellites, the deployment of local coordination layer controllers is not limited by inability of deploying ground stations globally and therefore the control of large-scale LEO satellite constellation can be achieved.

The present document relates to methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to configuring network slice-specific aggregate maximum bit rates (AMBRs). In one exemplary aspect, a method for wireless communication is disclosed. The method includes obtaining, by a first network function, one or more maximum bit rates that are specific to network slices configured for a terminal. The method also includes transmitting, by the first network function, the one or more maximum bit rates to a second network function, wherein the second network function is configured to limit a bit rate of network flows for the terminal according to the one or more maximum bit rates.

The present disclosure relates to technique for facilitating PDCCH monitoring in carrier aggregation for lower power consumption. A UE monitors a physical downlink control channel (PDCCH) on a secondary cell (SCell). The UE stops the PDCCH monitoring on the SCell in response to a monitoring-stoppage event. Then, the UE resumes the PDCCH monitoring on the SCell in response to a monitoring-resumption event. The SCell may remain active during a period between the stopping of the PDCCH monitoring and the resuming of the PDCCH monitoring.

A method of wireless communication includes receiving a first configuration for a first uplink (UL) transmission at a first time. The first configuration indicates a first transmission configuration indication (TCI) state and a first identifier (ID). A second configuration for a second UL transmission is received at a second time. The second configuration indicates a second TCI state and a second ID. The second UL transmission has a same priority or a same type as the first UL transmission. The first UL transmission is determined to be higher in a hierarchy than the second UL transmission based on a relationship between the first ID and the second ID. The first UL transmission is transmitted with the first TCI state based on the determined hierarchy. The second UL transmission is transmitted with the first TCI state or the second UL transmission is dropped based on the hierarchy.

The invention relates to a method for efficiently discarding data packets destined to a mobile station connected to both a master base station and a secondary base station. The master base station configures a secondary discard function in a lower layer of the secondary base station, based on the master discard function in the higher layer of the master base station. The master base station forwards the data packet from the higher layer to the lower of the secondary base station. The secondary discard function of the lower layer at the secondary base station discards the received data packet upon expiry of the secondary timer started by the lower layer upon reception of the data packet from the higher layer at the master base station.

Presented are systems, methods, apparatuses, or computer-readable media for data forwarding in centralized unit (CU) and distributed unit (DU) split architectures. A DU may receive, from a CU, context information for forwarding of data from a wireless communication device that is in radio resource control (RRC) inactive state. The DU may receive, from the wireless communication device, the data from the wireless communication device that is in RRC inactive state. The DU may process the data according to the context information. The DU may send, to the CU, the processed data according to the context information.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). The present application provides a method for establishing dual connectivity to ensure data continuity in 5G architecture. Related information of a mapping of a QoS Flow to a data radio bearer (DRB) is transmitted, by a first node, to a second node; the related information of the mapping carries indication information; response information in response to the information related to the mapping is received from the second node; and based on the response information, data is transmitted to the second node. The method of the present application may correctly configure dual connectivity resources, reduce signaling interaction, avoid configuration conflicts, optimize resource configuration, and improve the reliability of transmitting user data.

A master RAN node (1) sends, to a control plane function (5) in a core network (4), a modification request for modification of a first PDU session already established between a radio terminal (3) and a user plane function (6) in the core network (4). The modification request implicitly or explicitly indicates that PDU session split is needed for the first PDU session. The modification request causes the control plane function (5) to control the user plane function (6) to move a specific one or more QoS flows of a plurality of QoS flows associated with the first PDU session from a first tunnel between the user plane function (6) and the master RAN node (1) to a second tunnel between the user plane function (6) and a secondary RAN node (2). This contributes, for example, to implementing PDU session split in a radio communication network.

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may determine a preference of the UE for a termination point between a core network and a radio access network (RAN), the core network and the RAN supporting communications for the UE via at least one or a first cell and a second cell each associated with a multi-connectivity mode of the UE. The UE may transmit, to a base station, an indication of the preference of the UE for the termination point. In some cases, the base station may determine the termination point based on receiving the indication of the preference of the UE, and the base station may transmit a message indicating a configuration for the multi-connectivity mode to the UE, the configuration indicating the determined termination point.

An example of this disclosure provides a method (500) performed by a base station control unit (CU). The method comprises receiving (502) a request from a base station distributed unit (DU) to store information for a first plurality of cells to be served by the base station DU. The method also comprises sending (504) a response to the base station DU, wherein the response indicates that storing information for the first plurality of cells would exceed a maximum number of cells that can be stored by the base station CU.
