1. A method performed by a wireless device, the method comprising:
receiving, from a master node for multi-connectivity operation, a configuration message which includes a master configuration and one or more conditional PSCell configurations, wherein the master configuration is associated with the master node, wherein each conditional PSCell configuration comprises a PSCell configuration that the wireless device is to apply when an associated condition is fulfilled, wherein each PSCell configuration is a configuration of a primary cell of a secondary cell group associated with a secondary node for multi-connectivity operation;
transmitting a first message in response to the configuration message, wherein the first message indicates acknowledgement of receipt, applying of, and/or understanding of the master configuration; and
after transmitting the first message, when the condition for applying the PSCell configuration of at least one of the one or more conditional PSCell configurations is fulfilled, transmitting, to the master node, a second message that includes an indication indicating application by the wireless device of the PSCell configuration of at least one of the one or more conditional PSCell configurations.
