Document Type and Number:
WIPO Patent Application WO/2023/245346
Kind Code:
A1
Abstract:
This disclosure describes methods and apparatus to support multicast reception for UE in RRC INACTIVE state. A particular procedure is introduced to receive MRB configuration from the network, perform MRB establishment and update multicast MTCH information. When UE joins the multicast session when the session is not start yet, the network sends UE to RRC INACTIVE state by RRCRelease with suspendconfig. In one embodiment, the multicast MRB configuration is delivered in the suspendconfig, and UE stores the configuration in buffer. The UE will perform multicast MRB configuration procedure according to the stored configuration when UE receives the group paging notification for the multicast session.
