Successful primary secondary cell changes

Abstract

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of enabling a successful Mobility Robustness Optimization analysis for primary secondary cell (PSCell) changes. The method comprises transmitting, from a terminal device to a master node of the terminal device, information related to a node initiating a successful PSCell change for the terminal device, wherein the information is indicative of at least one of the following: whether the node initiating the successful PSCell change is either a master node or a secondary node for the apparatus; a cell identifier of the node initiating the successful PSCell change.
