Title:
METHODS AND APPARATUS OF MULTICAST RADIO BEARER ESTABLISHMENT FOR NR MULTICAST AND BROADCAST SERVICES
Document Type and Number:
WIPO Patent Application WO/2021/159229
Kind Code:
A1
Abstract:
Apparatus and methods are provided to support the establishment of Radio Bearer (s) at Base Station and UE to support Multicast data transmission corresponding to a Multicast session modified or established as request by 5GC. In one novel aspect, the UE establishes one SDAP entity for one Multicast session established as request by 5GC. The Base Station establishes one SDAP entity for one Multicast session established as request by 5GC, when the Base Station decides to use PTM RB to transmit the Multicast data. The Base Station sends a RRC message e. g. RRC Reconfiguration message including security configuration structure to the UE to configure the RB for Multicast data delivery.
