Abstract
Disclosed are methods and apparatus for conditional handover (CHO) in network. One embodiment of the subject application provides a method performed by a user equipment includes receiving, from a serving cell, a CHO configuration and at least an associated CHO execution conditions for a candidate cell, wherein the associated CHO execution condition includes at least a time-based condition; evaluating the associated CHO execution condition; and determining whether to execute a CHO based on the evaluation.
Claims22
A user equipment (UE) for wireless communication comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive from a serving cell, a conditional handover (CHO) configuration and at least an associated CHO execution condition for a candidate cell, the associated CHO execution condition including a time-based condition;
- evaluate the associated CHO execution condition;
- and
- determine whether to execute a CHO based on the evaluation.

A processor for wireless communication, comprising:
- at least one controller coupled with at least one memory and configured to cause the processor to:
- receive, from a serving cell, a conditional handover (CHO) configuration and at least an associated CHO execution condition for a candidate cell, the associated CHO execution condition including a time-based condition;
- evaluate the associated CHO execution condition;
- and
- determine whether to execute a CHO based on the evaluation.
A method performed by a user equipment (UE), the method comprising:
- receiving, from a serving cell, a conditional handover (CHO) configuration and at least an associated CHO execution condition for a candidate cell, the associated CHO execution condition including a time-based condition;

A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive, from a serving cell, a conditional handover (CHO) configuration and associated CHO execution condition for a candidate cell, the associated CHO execution condition including at least a time-based condition, the time-based condition including a first timer and a first measurement-based condition, and the time-based condition being fulfilled upon the first timer expiry;
- start the first timer upon reception of the CHO configuration and the associated CHO execution condition;
- evaluate the first measurement-based condition upon the time-based condition being fulfilled;
- and
- determine whether to execute a CHO at least according to a state of the associated CHO execution condition.
