Classification: CPC H | IPC H

Claim 3:
4. A wireless device adapted to operate in a wireless communication system, the wireless device comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, performs operations comprising:
receiving, from a network via the at least one processor, a Conditional Handover (CHO) configuration including one or more conditions of one or more candidate cells,
wherein the one or more conditions are based on any one of (i) a first event in which a candidate cell becomes amount of an offset better than the serving cell, or (ii) a second event in which the serving cell becomes worse than a first threshold and a candidate cell becomes better than a second threshold,
wherein the CHO configuration includes one or more configurations of each of the one or more candidate cells;
evaluating the one or more conditions of each of the one or more candidate cells;
considering the first event or the second event to be not fulfilled;
detecting a radio link failure upon expiry of a timer in the serving cell,
wherein the timer starts upon receiving N number of consecutive out-of-sync indications for the serving cell from lower layers;
performing a cell selection; and
(i) if the cell selection is triggered by detecting the radio link failure, and (ii) if a selected cell is one of the one or more candidate cells, applying a configuration associated to the selected cell,
wherein the selected cell is selected based on fulfilling a cell selection criterion S,
wherein the cell selection criterion S is different from the one or more conditions, and
wherein the cell selection criterion S is fulfilled when:
Srxlev>0 AND Squal>0
where:

SrxleV=Qrxlevmeas−(Qrxlevmin+Qrxlevminoffset)−Pcompensation−Qoffsettemp 

Squal=Qqualmeas−(Qqualmin+Qqualminoffset)−Qoffsettemp 

where:
Srxlev denotes a cell selection reception (RX) level value, Qrxlevmeas denotes a measured cell RX level value, Qrxlevmin denotes a minimum required RX level value in a cell, Qrxlevminoffset denotes an offset to the Qrxlevmin, Pcompensation denotes a parameter related to additionalPmax, Qoffsettemp denotes an offset temporarily applied to the cell, Squal denotes a cell selection quality value, Qqualmeas denotes a measured cell quality value, Qqualmin denotes a minimum required quality level value in the cell, and Qqualminoffset denotes an offset to the Qqualmin.
