receiving, by a user device, from a network device, an indication indicating:
that both of a first recovery operation via a second cell group and a second recovery operation via a secondary cell in a first cell group are allowed for a first cell group failure, and
available transmission paths for the first recovery operation and the second recovery operation;
upon a detection of the first cell group failure, determining a first transmission path for transmitting failure information based on the indication;
transmitting the failure information based on the determining of the first transmission path;
starting a guard timer; and
upon an expiry of the guard timer, transmitting the failure information based on a second transmission path.
