Document Type and Number:
WIPO Patent Application WO/2023/022478
Kind Code:
A1
Abstract:
The present disclosure provides a method for conditional handover by a user equipment (UE) in a 5G communication network. The method may include: receiving, by the UE, a conditional handover command, and an associated condition from the source cell; receiving, by the UE, a plurality of target cell configurations, from the source cell, having details for a plurality of target cells meeting a conditional handover criterion; evaluating, by the UE, the received associated condition for the conditional handover; and assigning priority to the received target cells configured in the conditional handover during the cell selection procedure. The method may include selecting one target cell for conditional handover from among the plurality of target cells based on the assigned priority.
