Method, apparatus and system relating to a mobility group indicator

Abstract

A method, e.g. performed by a user equipment (UE) connected to a first cell of a first distributed unit (DU) of a first base station is disclosed. The method comprises receiving configuration information for measuring at least part of a synchronization signal block (SSB) and/or a Channel State Information-Reference Signal (CSI-RS) associated with a physical cell ID (PCI) of a second cell and for observing information related to a mobility group indicator (MGI); measuring the at least part of SSB and/or CSI-RS that is associated with the PCI; and observing the information related to the MGI, wherein a combination of the measured at least part of SSB and/or CSI-RS and the information related to the MGI enables to determine at least one of: whether the second cell is an intra-DU cell, an inter-DU cell or an inter-base station cell with respect to the first cell. Corresponding methods performed by units of the first base station are disclosed. Further, a corresponding system and corresponding apparatuses, computer programs, and computer readable media are disclosed.
