Abstract
A method is presented in which a central unit of a distributed base station apparatus in a cellular communication system sends to a distributed unit of the distributed base station apparatus a first message comprising an information element for requesting the distributed unit of the distributed base station to provide a current distributed unit configuration. The central unit receives, from the distributed unit of the distributed base station apparatus, configuration information for the current distributed unit configuration in a second message sent in response to the first message.

A method performed by a gNB Central Unit, gNB-CU, in a communication system, the method comprising:
- sending, to a gNB Distributed Unit, gNB-DU, a user equipment, UE, CONTEXT MODIFICATION REQUEST message comprising an GNB-DU Configuration Query information element, IE, which is used to request the gNB-DU to provide configuration information for the gNB-DU;
- and
- receiving, from the gNB-DU, configuration information comprising a cell group configuration of the gNB-DU in a UE CONTEXT MODIFICATION RESPONSE message sent in response to the UE CONTEXT MODIFICATION REQUEST message.
A gNB Central Unit, gNB-CU, in a communication system, the gNB-CU comprising:
- a transceiver;
- and
- a controller configured to control the transceiver to:
- send, to a gNB Distributed Unit, gNB-DU, a user equipment, UE, CONTEXT MODIFICATION REQUEST message comprising an GNB-DU Configuration Query information element, IE, which is used to request the gNB-DU to provide configuration information for the gNB-DU;
- and
- receive, from the gNB-DU, configuration information comprising a cell group configuration of the gNB-DU in a UE CONTEXT MODIFICATION RESPONSE message sent in response to the UE CONTEXT MODIFICATION REQUEST message.
