Abstract
A radio access network (RAN) node (11) is configured to send, to another RAN node (12), first control information regarding at least one of one or more bandwidth parts (BWPs) configured in a system bandwidth. It is thus, for example, possible to contribute to inter-radio access network (RAN) node (e.g., inter-gNB) signaling enhanced to handle bandwidth parts.

1-4. (canceled)
A method for a gNB Distributed Unit (gNB-DU) hosting a Physical (PHY) layer and a Medium Access Control (MAC) layer, the method comprising:
- communicating with a User Equipment (UE);
- and
- sending, via an F1 interface, a message to a gNB Central Unit (gNB-CU) hosting a Radio Resource Control (RRC) layer, the message including first information indicating one or more bandwidth parts to be configured for the UE and second information indicating at least one of the one or more bandwidth parts to be activated for the UE.
A method for a gNB Central Unit (gNB-CU) hosting a Radio Resource Control (RRC) layer, the method comprising:
- communicating with a User Equipment (UE);
- and
- receiving, via an F1 interface, a first message from a gNB Distributed Unit (gNB-DU) hosting a Physical (PHY) layer and a Medium Access Control (MAC) layer, the first message including information indicating one or more bandwidth parts to be configured for the UE and information indicating at least one of the one or more bandwidth parts to be activated for the UE.
A gNB Distributed Unit (gNB-DU) configured to host a Physical (PHY) layer and a Medium Access Control (MAC) layer, the gNB-DU comprising:
- an F1 interface configured to connect the gNB-DU to a gNB Central Unit (gNB-CU) hosting a Radio Resource Control (RRC) layer;
- and
- a processor configured to send to the gNB-CU, via the F1 interface, a message including first information indicating one or more bandwidth parts to be configured for a User Equipment (UE) and second information indicating at least one of the one or more bandwidth parts to be activated for the UE.
A gNB Central Unit (gNB-CU) configured to host a Radio Resource Control (RRC) layer, the gNB-CU comprising:
- an F1 interface configured to connect the gNB-CU to a gNB Distributed Unit (gNB-DU) hosting a Physical (PHY) layer and a Medium Access Control (MAC) layer;
- and
- a processor configured to receive from the gNB-DU, via the F1 interface, a message including information indicating one or more bandwidth parts to be configured for a User Equipment (UE) and information indicating at least one of the one or more bandwidth parts to be activated for the UE.
