Abstract
In wireless communication, a device may change, add, or handover between providers (e.g. nodes) of network access. This may include a conditional cell addition/change procedure initiated by a master node. In addition, successive cell addition/changes can also be performed. The conditional procedures and/or successive procedures can reduce handover interruption time and improve reliability.
Claims20
A method for wireless communication comprising:
- sending, by a master node (MN) to a target secondary node, a secondary node (SN) addition request for a SN change from a source SN or a SN addition of the target SN, wherein the request comprises candidate cell information for the target SN;
- receiving, by the MN from the target SN, a response that includes at least one candidate cell configuration;
- and
- sending, by the MN to a user equipment (UE), a radio resource control (RRC) message with at least one candidate cell configuration and one or more execution conditions for each candidate cell to cause a change from the source SN to the target SN or a SN addition of the target SN based on a candidate cell configuration of the at least one candidate cell configuration when the one or more execution conditions for one of the candidate cells from the target SN are met.

- performing, by a UE, a change from a source secondary node (SN) to a target secondary node (SN) or a secondary node (SN) addition of the target secondary node based on the candidate cell configuration when the one or more execution conditions for one of the candidate cells from the target SN are met.
