Abstract:
Aspects relate to wireless communication where a master node (MN) or a secondary node (SN) may initiate a conditional addition of a primary secondary cell (PSCell) or a conditional change from one PSCell to another PSCell. Each candidate target PSCell may provide information to be used by the MN to generate a conditional PSCell addition (CPA) configuration or a conditional PSCell change (CPC) configuration that is sent to a user equipment (UE). This information may indicate an execution condition for each candidate target PSCell and/or radio bearers that each candidate target PSCell supports or does not support. An MN may modify a master cell group (MCG) configuration for a PSCell based on information received from a target SN with an secondary cell group (SCG) configuration for the PSCell. The MN may transmit a CPA or CPC configuration including the modified MCG configuration and the SCG configuration to the UE.
