A Method to Tailor Broadcasting and Multicasting Transmission in 5G New Radio

Abstract

Broadcast and multicast will be an important feature supported in 5G New Radio. In this paper a new transmission method is proposed to improve the receiver side User Equipment (UE) resource efficiency by using redundant multicast channels at the transmitting Base Station (BS). Transmission is tailored for UEs with different channel characteristics. A sub-grouping algorithm is designed to fast allocate UEs of a multicast group to their most suitable channels. Numeric sample calculation proves the validity of the proposed method.

Optimization of hybrid broadcast/broadband networks for the delivery of linear services using stochastic geometry

“…Further enhancements were introduced in 3GPP release-14 in order to support the television services following broadcasting industry requirements, bringing on better interference enhancements, increasing the inter-site distance, dedicating carriers for eMBMS with full broadcasting resource allocation [119]. The capabilities of MC in the 5G network was also studied in the literature like in [120][121][122] Several trial deployments were done in Europe, the United States and Australia, mainly for broadcasting sports events, between 2014 and 2016. South Korea was the first to deploy eMBMS commercially [71].…”
