Abstract

A first network node and method therein for handling an operation mode change of a second network node for a communication device in a wireless communication network are disclosed. The communication device is configured with multi-radio dual connectivity (MR-DC) with the first network node having a first cell group and the second network node having a second cell group. The first network node receives () a request from the second network node for a change of operation mode and/or a change of configuration of the second network node and determines () whether to accept or reject the request for the change of the operation mode and/or a change of configuration. The first network node transmits () to the communication device a message including a reconfiguration or command to change the second cell group configuration and/or the operation mode of the second cell group, if it is determined that the change of operation mode of the second cell group and/or change of the second cell group configuration is accepted; or transmits () a response to the second network node with an indication indicating a rejection reason, if it is determined to reject the request for the change of the operation mode.
