Support of SC-PTM based multicasting for BL/CE and NB-IoT UEs
Support of Single-Cell Point-To-Multipoint (SC-PTM) for narrowband (UEs) and low complexity (BL) UEs can is implemented at both the physical layers and the higher layers. For example, in one implementation, a UE may transmit, to a Single-Cell Point-To-Multipoint (SC-PTM) base station, multicast service preference information, including at least one of a Coverage Enhancement (CE) mode or a maximum Transport Block Size (TBS) of the UE. The UE may also monitor a common search space (CSS) of a MTC Physical Downlink Control Channel (MPDCCH) or Narrowband Physical Data Control Channel (NPDCCH) for the scheduling of a Physical Downlink Shared Channel (PDSCH) or a Narrowband Physical Downlink Shared Channel (NPDSCH), respectively, to obtain downlink control information (DCI) that includes configuration information relating to a Single-Cell Multicast Control Channel (SC-MCCH).
