Abstract: A user equipment (UE) may receive, from a first network entity, an indication of a configuration for the UE to report, to the first network entity, an estimate of a first timing advance value for a second network entity. The UE may determine the estimate of the first timing advance value. The UE may transmit, to the first network entity, the estimate of the first timing advance value for the second network entity or a reference signal time difference associated with the estimate of the first timing advance value. The UE may receive, from the first network entity, an indication of an error value associated with the estimate of the first timing advance value. The UE may determine a second timing advance value based on the estimate of the first timing advance value and the error value. The UE may transmit communications using the second timing advance value.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage medium for conditional cell changes. In a method, a network device transmits, to a plurality of candidate target network devices, an indication of a plurality of candidate target cells of the plurality of candidate target network device. The network device receives, from the plurality of candidate target network devices, first information related to measurements for changes between the plurality of candidate target cells. Then the network device transmits, to a terminal device, second information related to the measurements for use in executing of the change from a first candidate target cell to a second candidate target cell among the plurality of candidate target cells after handover from a source cell to the first candidate target cell.

Abstract: Embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage media for master node centric reference configuration generation. In the methods, a master node receives, from at least one secondary node, respective cell configurations of one or more cells prepared as candidate primary secondary cells for a terminal device. Then, the master node generates a reference configuration for the one or more cells based on the respective cell configurations, and obtains respective delta configurations for the one or more cells. A delta configuration represents a difference between a cell configuration of a respective cell and the reference configuration. Moreover, the master node transmits the reference configuration and the respective delta configurations to at least one of the terminal device, or a serving secondary node of the terminal device. Thereby, the proposed solutions can advantageously minimize the signaling overhead.
