METHODS AND APPARATUS FOR CONDITIONAL PSCELL ADDITION/CHANGE AND CONDITIONAL HANDOVER INTERWORKING AND RLF HANDLING

The disclosure pertains to methods and apparatus configured to receive, from a first base station, conditional primary secondary cell addition configuration information indicating one or more candidate primary secondary cells of a second base station, a detection of a radio link failure on a primary cell of the first base station and a signal quality threshold associated with the one or more candidate primary secondary cells; perform a primary secondary cell addition of a primary secondary cell based on a signal quality of the primary secondary cell and the signal quality threshold; send, to the second base station, first information comprising an indication of a completion of the primary secondary cell addition; and send, to the first base station using resources of the second base station, second information comprising an indication of the radio link failure on the primary cell of the first base station.
