METHOD AND USER EQUIPMENT FOR CONDITIONAL HANDOVER IN MULTI-RAT DUAL CONNECTIVITY NETWORK
A method performed by a UE for a conditional handover (CHO) in an MR-DC network is provided. The method receives a message including an execution condition for a PCell, a first SCG configuration for a first PSCell, an execution condition for the first PSCell, and a second SCG configuration for a second PSCell. The method stores the first SCG configuration and the second SCG configuration. The method determines whether the execution condition for the PCell is satisfied and whether the execution condition for the first PSCell is satisfied. The method applies the first SCG configuration after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is satisfied. The method applies the second SCG configuration after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is not satisfied.
1 . A method performed by a user equipment (UE) for a conditional handover (CHO) in a multi-radio access technology (RAT) dual connectivity (MR-DC) network, the method comprising:
receiving a message comprising an execution condition for a primary cell (PCell), a first secondary cell group (SCG) configuration for a first primary secondary cell (PSCell), an execution condition for the first PSCell, and a second SCG configuration for a second PSCell;
storing the first SCG configuration and the second SCG configuration;
determining whether the execution condition for the PCell is satisfied and whether the execution condition for the first PSCell is satisfied;
applying the first SCG configuration after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is satisfied; and
applying the second SCG configuration after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is not satisfied.
2 . The method of claim 1 , further comprising connecting, based on the first SCG configuration, to the first PSCell after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is satisfied.
3 . The method of claim 1 , further comprising connecting, based on the second SCG configuration, to the second PSCell after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is not satisfied.
4 . The method of claim 1 , wherein receiving the message comprises receiving the message via radio resource control (RRC) signaling.
5 . A user equipment (UE) for a conditional handover (CHO) in a multi-radio access technology (RAT) dual connectivity (MR-DC) network, the UE comprising:
one or more processors; and
at least one non-transitory computer-readable medium coupled to at least one of the one or more processors, and storing one or more computer-executable instructions that, when executed by the at least one of the one or more processors, cause the UE to:
receive a message comprising an execution condition for a primary cell (PCell), a first secondary cell group (SCG) configuration for a first primary secondary cell (PSCell), an execution condition for the first PSCell, and a second SCG configuration for a second PSCell;
store the first SCG configuration and the second SCG configuration;
determine whether the execution condition for the PCell is satisfied and whether the execution condition for the first PSCell is satisfied;
apply the first SCG configuration after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is satisfied; and
apply the second SCG configuration after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is not satisfied.
6 . The UE of claim 5 , wherein the one or more computer-executable instructions, when executed by the at least one of the one or more processors, further cause the UE to connect, based on the first SCG configuration, to the first PSCell after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is satisfied.
7 . The UE of claim 5 , wherein the one or more computer-executable instructions, when executed by the at least one of the one or more processors, further cause the UE to connect, based on the second SCG configuration, to the second PSCell after determining that the execution condition for the PCell is satisfied and the execution condition for the first PSCell is not satisfied.
8 . The UE of claim 5 , wherein receiving the message comprises receiving the message via radio resource control (RRC) signaling.
