Abstract

Provided is a terminal apparatus including a receiver configured to receive an RRC message including configuration information of an MBS from a base station apparatus, and a processing unit. The configuration information of the MBS includes MBS session information. The MBS session information includes PDU session information. The processing unit, based on initiation of reception of the MBS session by the terminal apparatus, establishes a radio bearer for the MBS, and performs processing of notifying a higher layer of a part or all of the MBS session information.

Claims (14)

1. A terminal apparatus that communicates with a base station apparatus, the terminal apparatus comprising:

a receiver configured to receive a Radio Resource Control (RRC) message including configuration information of a Multicast Broadcast Service (MBS) from the base station apparatus; and

a processor, wherein

the configuration information of the MBS includes information of an MBS session,

the processor establishes an MBS Radio Bearer (MRB) to receive the MBS session, and

the processor, in a case that the MRB is established,

establishes a Packet Data Convergence Protocol (PDCP) entity for the MRB, and

establishes a Service Data Adaptation Protocol (SDAP) entity in a case that the SDAP entity for the MBS session does not exist.

2. A method performed by a terminal apparatus that communicates with a base station apparatus, the method comprising:

receiving a Radio Resource Control (RRC) message including configuration information of a Multicast Broadcast Service (MBS) from the base station apparatus, wherein the configuration information of the MBS includes information of an MBS session; and

establishing an MBS Radio Bearer (MRB) to receive the MBS session, wherein

in a case that the MRB is established, the method further comprises:

establishing a Packet Data Convergence Protocol (PDCP) entity for the MRB, and

establishing a Service Data Adaptation Protocol (SDAP) entity in a case that the SDAP entity for the MBS session does not exist.
