Method for receiving multicast data and apparatus thereof

Abstract:

A method may be provided for receiving multicast data by an IoT terminal requiring a low power and a low cost and an apparatus thereof. The method of a terminal may include starting a single cell-point to multipoint (SC-PTM) onduration timer through a MAC when discontinuous reception (DRX) is configured for a group-radio network temporary identifier (G-RNTI); monitoring a physical downlink control channel (PDCCH) during an active time; controlling at least one of the SC-PTM onduration timer and the SC-PTM inactivity timer when the PDCCH includes information indicating downlink transmission; and repeatedly receiving the multicast data through a physical downlink shared channel (PDSCH) of one or more subframes and an apparatus thereof.
