Method and device for transmitting or receiving multicasting data channel for NB-IoT terminal

Abstract:

Provided is a method of supporting Single Cell Point-to-Multi-point (SC-PTM) for a Bandwidth reduced Low complexity/Coverage Enhancement (BL/CE) terminal or an NB-IoT terminal, which are for a Machine Type Communication (MTC) application defined in a 3GPP LTE/LTE-A system. The method may include receiving configuration information of an NPDCCH search space from a base station, wherein the NPDCCH search space is separately configured to receive scheduling control information for the multicasting data channel; receiving the scheduling control information for the multicasting data channel through the NPDCCH search space configured based on the configuration information; and receiving the multicasting data channel based on the scheduling control information.
