Abstract
A communication system is disclosed in which Multicast and Broadcast Services (MBS) may be provided via multicast, for user equipment (UE) in an inactive state. A distributed unit of a base station apparatus receives, from a central unit of the base station apparatus, information identifying at least one MBS session and information identifying that the at least one MBS session is to be provided in a cell via multicast for the UE in the inactive state.

A method performed by a distributed unit of a base station for providing Multicast and Broadcast Services (MBS) in a cell for a user equipment (UE) in a Radio Resource Control (RRC) inactive state, the method comprising:
- receiving, from a central unit of the base station, MBS session information indicating whether a transmission mode via multicast to the UE in the RRC inactive state on at least one MBS session is to be activated in the cell or to be deactivated;
- and
- determining to activate the transmission mode via multicast to the UE in the RRC inactive state on the at least one MBS session in the cell or deactivate the transmission mode via multicast to the UE in the RRC inactive state on the at least one MBS session, based on the MBS information.
A method performed by a central unit of a base station for providing Multicast and Broadcast Services (MBS) in a cell for a user equipment (UE) in a Radio Resource Control (RRC) inactive state, the method comprising:
- transmitting, to a distributed unit of the base station, MBS session information identifying whether a transmission mode for the UE in the RRC inactive state on at least one MBS session is to be activated in the cell via multicast or to be deactivated, wherein
- the MBS session information is used by the distributed unit for determining to activate the transmission mode for the UE in the RRC inactive state on the at least one MBS session in the cell via multicast or deactivate the transmission mode for the UE in the RRC inactive state on the at least one MBS session.
A distributed unit of a base station for providing Multicast and Broadcast Services (MBS) in a cell for a user equipment (UE) in a Radio Resource Control (RRC) inactive state, the distributed unit comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- receive, from a central unit of the base station, MBS session information identifying whether a transmission mode for the UE in the RRC inactive state on at least one MBS session is to be activated in the cell via multicast or to be deactivated;
- and
- determine to activate the transmission mode for the UE in the RRC inactive state on the at least one MBS session in the cell via multicast or deactivate the transmission mode for the UE in the RRC inactive state on the at least one MBS session, based on the MBS session information.
A central unit of a base station for providing Multicast and Broadcast Services (MBS) in a cell for a user equipment (UE) in a Radio Resource Control (RRC) inactive state, the central unit comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- transmit, to a distributed unit of the base station, MBS session information identifying whether a transmission mode for the UE in the RRC inactive state on at least one MBS session is to be provided in the cell via multicast or to be deactivated, wherein
- the MBS session information is used by the distributed unit for determining to activate the transmission mode for the UE in the RRC inactive state the at least one MBS session in the cell via multicast or deactivate the transmission mode for the UE in the RRC inactive state on the at least one MBS session.
