Certain aspects of the present disclosure provide techniques for dynamically determining an uplink data split threshold for communicating using one or more radio link control (RLC) entities of a split bearer configuration. A method that may be performed by a user equipment (UE) includes inputting a first set of parameters to a machine learning algorithm, obtaining, as an output of the machine learning algorithm based at least in part on the inputted first set of parameters, a value for a data split threshold, and transmitting the data using at least one of a first RLC entity or the second RLC entity based on the value for the data split threshold and the amount of data the apparatus has to transmit

In a data packet transmission method disclosed herein, a capability information value indicating an amount of data that can be supported by a data transmission end is determined. In response to determining that a data packet is not received correctly, a data packet to be retransmitted is determined and is retransmitted according to the capability information value.

An electronic device for a backhaul network, wherein the backhaul network comprises a first communication apparatus connected to a core network and a plurality of second communication apparatuses performing wireless communication with the first communication apparatus, includes: processing circuitry configured to perform control to cause the first communication apparatus comprising the electronic device to: operate as a primary donor; select at least one second communication apparatus of the plurality of second communication apparatuses as a secondary donor; transmit a first indicating signal to the selected at least one second communication apparatus, the first indicating signal comprising node type information indicating the secondary donor; transmit a second indicating signal to a second communication apparatus that are not selected, the second indicating signal comprising node type information indicating a member node.

Provided is a control apparatus that controls any one or all of a plurality of slave station apparatuses communicating with a terminal apparatus, a plurality of master station apparatuses that control the slave station apparatuses, and a transfer apparatus that transfers data transmitted and received between the master station apparatuses and the slave station apparatuses, the control apparatus including an information acquisition unit that acquires information regarding traffic of the data transmitted and received between the master station apparatuses and the slave station apparatuses, and a switching control unit that performs, on the basis of the information regarding the traffic acquired by the information acquisition unit, switching-control of an assignment relationship between the master station apparatus and the slave station apparatus and switching-control of a transfer path of data between the master station apparatus and the slave station apparatus.

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.

Techniques for measuring and reducing signal misalignment in a dual connectivity environment are discussed herein. When using Non-Standalone Architecture (NSA), a device initially communicates with a network using a Long-Term Evolution (LTE) connection. After the LTE connection is established, an LTE base station may instruct the device to measure signal strength of a neighboring New Radio (NR) cell during a specified LTE measurement gap. When the NR cell is implemented by an indoor NR base station, the NR signal may not be sufficiently synchronized with the LTE signal and the device may be unable to measure the NR signal during the measurement gap. In these cases, the device can determine the frame timing difference between the LTE and NR signals, obtain an adjusted measurement gap that reduces any measurement gap misalignment, and attempt to measure the signal strength of the NR cell using the adjusted measurement gap.

A method including using master cell group resources for a downlink data transmission to a user equipment, wherein the user equipment is configured with at least one secondary cell group terminated split bearer and a secondary cell group is deactivated; determining, at a centralized central unit user plane, when secondary cell group resources of the deactivated secondary cell group are needed, wherein the determining is based, at least partially, on a data volume threshold for a data radio bearer as configured by a central unit control plane; and based upon the determining that the secondary cell group resources are needed, sending a notification to the central unit control plane to trigger activation of the secondary cell group resources.

A terminal device includes an estimation unit and a distribution unit. The estimation unit estimates the radio transmission capacity of a second radio transmission path on the basis of a reception level of a radio signal from each of a first radio transmission path and the second radio transmission path. The second transmission path includes at least one radio repeater and is divided into two with the radio repeater disposed in between so that one side thereof towards the communication apparatus serves as a first radio section and the other side thereof opposite to the one side serves as a second radio section. The distribution unit distributes the data input thereto to the first radio transmission path and to the second radio transmission path on the basis of the radio transmission capacity of the first radio transmission path and the estimated radio transmission capacity of the second radio transmission path.

The present invention relates to the field of communications technologies, and in particular, to an RLC data packet offloading method and a base station, so as to solve a problem that performance of UE in a CA scenario of a non-ideal backhaul HetNet is affected due to a relatively long transmission delay between a macro eNodeB and a micro eNodeB. In embodiments of the present invention, a micro eNodeB may request a required RLC data packet before scheduling is performed; therefore, a macro eNodeB can send, to the micro eNodeB in advance, the RLC data packet required by the micro eNodeB, which reduces a transmission delay between the macro eNodeB and the micro eNodeB as much as possible, and improves receiving performance of UE.
