Abstract
A RAN node for communicating with a UE, which is configured to receive unicast information from a RAN, receives (1502) an indication that the UE is attempting to receive MBS, and transmits (1504), to another RAN node, a message that (i) notifies the second node of a first reconfiguration of the UE at the first node, or (ii) causes, at the second node, a second reconfiguration of the UE to receive the unicast information and MBS.
Claims21
A method in a first node operating in a radio access network (RAN) for communicating with a user equipment (UE), the UE configured to receive unicast information from the RAN, the method comprising:
- receiving, by the first node, an indication that the UE is attempting to receive multicast and broadcast services (MBS);
- and
- transmitting, by the first node to a second node operating in the RAN, a message that (i) notifies the second node of a first reconfiguration of the UE at the first node, or (ii) causes, at the second node, a second reconfiguration of the UE to receive the unicast information and MBS,
- the first node being a central unit (CU) of a first distributed base station and the second node being a distributed unit (DU) of the first distributed base station or a DU of a second distributed base station.
(canceled)
A method in a user equipment (UE) configured to receive unicast information from a radio access network (RAN), the method comprising:
- transmitting, by the UE and to a first network node that is operating in the RAN and that is a central unit (CU) of a first distributed base station, an indication that the UE is attempting to receive multicast and broadcast services (MBS) from the RAN;
- receiving, by the UE and from a second network node that is operating in the RAN and that is a distributed unit (DU) of the first distributed base station or a DU of a second distributed base station, a configuration generated in view of the indication;
- and
- receiving, by the UE, the unicast information and MBS according to the configuration.
