Abstract:
Systems, methods and apparatus are disclosed for handling conditional handover configurations by wireless devices and network nodes.
An example method performed by a wireless device includes receiving and storing one or more conditional handover configurations associated with a target cell candidate. The wireless device transitions from a connected state to a sleeping state, where the transition includes discarding the conditional handover configurations. The wireless device releases resources associated with the conditional handover configurations and performs clean up actions relating to conditional handover.
An example method performed by a network node includes providing, to a user equipment, one or more conditional handover configurations that are associated with a target cell candidate. The network node transmits, to the user equipment, a message to transition from a connected state to a sleeping state. After transmitting the message, the network node discards the conditional handover configurations.
