DETECTING PHYSICAL CELL IDENTIFIER (PCI) CONFUSION DURING SECONDARY NODE (SN) CHANGE PROCEDURE IN WIRELESS NETWORKS

Abstract: embodiments of the present disclosure disclose first secondary node element (-) for detecting physical cell identifier (pci) confusion during secondary node (sn) change procedure. the first secondary node element (-) receives secondary cell group (scg) failure information from ue () during handover from first secondary node element (-) to second secondary node element (-), indicating cause of failure of handover as random access channel failure. the first secondary node element (-) suspects that failure is due to pci confusion associated with pci of second secondary node element (-), based on cause, within pre-determined time period of timer configured at primary node element () for holding context of ue () at first secondary node element (-). the first secondary node element (-) performs mitigation action during subsequent handover from to secondary node elements, for ues in wireless network, when pci of one of secondary node elements is same as suspected pci.
