Abstract
A distributed unit (DU) of a distributed base station including a central unit (CU) and the DU can implement a method for configuring a user equipment (UE) to receive multicast and/or broadcast services (MBS). The method may include: receiving (1002), from the CU, a CU-to-DU message identifying an MBS session and requesting that the DU configure resources for the MBS session; and transmitting (1004), to the UE in response to receiving the CU-to-DU message, configuration parameters for receiving the MBS session.
Claims20
A method implemented in a distributed unit (DU) of a distributed base station including a central unit (CU) and the DU, for configuring a user equipment (UE) to receive multicast and/or broadcast services (MBS), the method comprising:
- receiving, by a processing hardware of the DU from the CU, an MBS context setup request for an MBS session, to request that the DU configure resources for the MBS session, the MBS context setup request including a packet data convergence protocol (PDCP) configuration;
- in response to receiving the MBS context setup request, transmitting, by the processing hardware to the UE, configuration parameters for receiving the MBS session including at least the PDCP configuration.
A method implemented in a central unit (CU) of a distributed base station including a distributed unit (DU) and the CU, for configuring a user equipment (UE) to receive multicast and/or broadcast services (MBS), the method comprising:
- receiving, by processing hardware of the CU from a core network (CN), a CN-to-BS message requesting that the distributed base station configure resources for an MBS session;
- and
- transmitting, by the processing hardware to the DU, an MBS context setup request identifying the MBS session and including a packet data convergence protocol (PDCP) configuration to cause the DU to transmit, to the UE, configuration parameters for receiving the MBS session including the PDCP configuration.
A network node, configured to configure a user equipment (UE) to receive multicast and/or broadcast services (MBS), the network node operating as a distributed unit (DU) of a distributed base station including a central unit (CU) and the DU, and the network node comprising:
- a transceiver;
- and
- processing hardware, configured to:
- receive, from the CU, an MBS context setup request for an MBS session, to request that the DU configure resources for the MBS session, the MBS context setup request including a packet data convergence protocol (PDCP) configuration;
- in response to receiving the MBS context setup request, transmit, to the UE, configuration parameters for receiving the MBS session including at least the PDCP configuration.
