Abstract
Improved techniques of intra and inter distributed unit mobility include determining, by a user equipment served by a source cell, whether a target cell belongs to the same distributed unit as the source cell based on information sent by the central unit (control plane) after a connection with the network node has been established. The information sent by the network node includes, for each cell, a group identifier identifying the distributed unit with which that cell is associated. When measurement data provided by the user equipment indicates readiness for a serving cell change to a target cell, the user equipment uses the group identifier to determine whether the target cell belongs to the same distributed unit as the source cell (intra-distributed unit mobility scenario) or a different distributed unit as the source cell (inter-distributed unit mobility scenario).
