Mobility-Enabled Dynamic Grouping for Multicast Broadcast Service

Abstract

3GPP has established the Multicast Broadcast Services (MBS) standard to accommodate the escalating bandwidth demands of emerging applications like mixed reality and online gaming. MBS offers an efficient means of simultaneously delivering content to different users through the same wireless resources. However, the efficacy of grouping is intricately linked to user mobility and the channel quality of the weakest link. Notably, it is identified that handovers can cause significant interruptions in MBS transmissions. To address this, our paper introduces a novel dynamic grouping scheme capable of adapting to user mobility. Our results demonstrate superior performance compared to state-of-the-art methods without introducing much signaling overhead associated with MBS group management.
