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.
