Problems solved by technology

As a result, LTE SC-PTM does not support retransmissions, because different SC-MTCHs are not uniquely identifiable, and thus the UE cannot indicate to the base station which data to retransmit
Furthermore, LTE SC-PTM is a multicast / broadcast only system, and communications cannot be switched between multicast / broadcast and unicast, such as for retransmissions to a single UE or individual retransmissions to a small group of UEs

Abstract

In general, various aspects of the present disclosure relate to wireless communications. In some aspects, a user equipment (UE) may receive an indication of a pattern for mapping a multicast broadcast quality of service (MB-QoS) flow to a logical channel identifier and a group radio network temporary identifier (G-RNTI); identifying an MB-QoS flow from a medium access control (MAC) transport block (TB) based at least in part on the indicated pattern; and decoding the data included in the MB-QoS stream. Various other aspects are provided.
