Abstract:
Systems and techniques for changing between secondary cells in dual connectivity communication. A user device (110A) operating in dual connectivity with a master base station (102) and a source base station (106A) transmits a change request to a target secondary base station (106B), seeking a connection change to a target base station that is to be used as the secondary base station. The target base station (106B) notifies the master base station (102) of the change request, and the master base station performs changeover operations—for example, notifying the source base station (106A) that it is no longer to be used in dual connectivity with the user device (110A) making the request, and notifying the user device (110A) that the change request has been accepted, with the user device (110A) then proceeding to establish connection with the target secondary base station (106B).

Abstract:
The present disclosure relates to a machine-learning (ML) orchestrator entity that provides distributed, flexible, and efficient parameter initialization for ML agents installed on network nodes operating under similar radio conditions. For this end, the ML orchestrator entity instructs two or more of the network nodes to run two or more ML agents in a training mode, which results in generating two or more sets of parameters. Then, the ML orchestrator entity uses the sets of parameters to derive a common set of parameters for the network nodes. The common set of parameters is to be used in an inference mode of the ML agent at each of the network nodes. The transmission of the common set of parameters to the network nodes may be subsequently initiated by the ML orchestrator entity itself or by each of the network nodes independently.
Abstract:
An apparatus performs classifying received data frames into a plurality of classes based on parameters of the received data frames, and determining a class from the plurality of classes for a next data frame based on the parameters of the previously received data frames. The determination is performed before the next data frame has arrived. A scheduling configuration is determined from a plurality of scheduling configurations based on the determined class of the next data frame. Each of the plurality of scheduling configurations comprises at least one parameter. The at least one parameter of the selected scheduling configuration is adjusted based on i) the determined class of the next data frame, and ii) information about previous communications of data frames by the network entity. The selected scheduling configuration is activated in the terminal with the at least one adjusted parameter.
Abstract:
There is provided an apparatus, said apparatus comprising means for, at a first network entity, determining that first resources scheduled for use by a first cell for communication with a user equipment are available at a second cell, receiving an indication from the user equipment to trigger handover from the first cell to the second cell and causing handover of the user equipment from the first cell to the second cell such that the second cell uses the first resources for communication with the user equipment.
Abstract:
Methods and apparatuses for Orthogonal Frequency Division Multiplexing (OFDM) based communication are disclosed. In a method at least some least important bits derived from data to be transmitted are mapped into at least one portion of an OFDM transmission unit, the at least one portion being reserved for the least important bits. More important bits derived from said data are mapped into a different portion of the ODFM transmission unit.
Abstract:
A technique includes making a decision to perform a handover of a user device from a source cell to a target cell at a scheduled handover time, determining, by a source base station associated with the source cell, an estimated data rate for transmitting data from the source cell to the user device between a time of the handover decision and the scheduled handover time, determining, based on the estimated data rate and a difference between the time of the handover decision and the scheduled handover time, a portion of data stored in a data buffer associated with the source cell for the user device to be forwarded to the target cell before the scheduled handover time, and forwarding, from the source cell to the target cell before the scheduled handover time, the portion of data stored in the data buffer for the user device.
Abstract:
This document discloses a solution of interference coordination in wireless communication systems where a base station may request a specified load report from another base station. A first base station may store load information of terminal devices associated with the identifier of strongest interference source for each terminal device. The first base station may receive a load report request from a second base station. The first base station may respond to the second base station with a load report including load information of only terminal devices whose strongest interference source is the second base station. The second base station may receive the load report further and provide communication resources on the basis of the received load report.
