Abstract
In wireless communication, a device may change, add, or handover between providers (e.g. nodes) of network access. This may include a conditional handover procedure. In addition, successive handovers can also be performed. The conditional procedures and/or successive procedures can reduce handover interruption time and improve reliability.
Claims21
A method for wireless communication comprising:
- sending, by a source node to a target node, a conditional handover (CHO) request that includes candidate cell information;
- receiving, by the source node from the target node, at least one candidate cell configuration in a CHO request response to the CHO request;
- and
- sending, by the source node to a user equipment (UE), a radio resource control (RRC) message including at least one candidate cell configuration and one or more CHO execution conditions for each candidate cell to cause a CHO process from a source cell to a target candidate cell based on a candidate cell configuration among the at least one candidate cell configuration when the one or more CHO execution conditions for an associated candidate cell are met.
A method for wireless communication comprising:
- receiving, by a target node from a source node, a conditional handover (CHO) request that includes candidate cell information;
- sending, by the target node to the source node, at least one candidate cell configuration in a CHO request response to the CHO request;
- and
- wherein the source node sends to a user equipment (UE), a radio resource control (RRC) message including at least one candidate cell configuration and one or more CHO execution conditions for each candidate cell to cause a CHO process from a source cell to a target candidate cell based on a candidate cell configuration among the at least one candidate cell configuration when the one or more CHO execution conditions for an associated candidate cell are met.
A method for wireless communication comprising:
- receiving, by a user equipment (UE) from a source node, a radio resource control (RRC) message including at least one candidate cell configuration and one or more conditional handover (CHO) execution conditions for each candidate cell;
- and
- performing, by the UE, a CHO process from a source cell to a target candidate cell based on the candidate cell configuration when the one or more CHO execution conditions for an associated candidate cell are met.
A wireless communications apparatus comprising a processor and a memory, wherein the processor is configured to read code from the memory and implement a method:
- receiving, by a user equipment (UE) from a source node, a radio resource control (RRC) message including at least one candidate cell configuration and one or more conditional handover (CHO) execution conditions for each candidate cell;
- and
- performing, by the UE, a CHO process from a source cell to a target candidate cell based on a candidate cell configuration among the at least one candidate cell configuration when the one or more CHO execution conditions for an associated candidate cell are met.
