Classification: CPC H | IPC H

Claim 10:
11. A base station operating in a wireless communication system, the base station comprising:
at least one transceiver;
at least one processor; and
at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
transmitting, to a user equipment (UE), resource reservation configuration information that includes i) information for slot level resource reservation and ii) information for symbol level resource reservation;
transmitting, to the UE, downlink control information (DCI) which includes resource reservation information,
wherein at least one NarrowBand (NB)-Internet of Things (IoT) DownLink (DL) subframe is determined based on the resource reservation configuration information and the resource reservation information,
wherein, based on the resource reservation information being set to “0”, all of OFDM symbols in the at least one NB-IoT DL subframe are reserved,
wherein, based on the resource reservation information being set to “1”, some of OFDM symbols in the at least one NB-IoT DL subframe are reserved; and
transmitting, to the UE, a Narrowband physical downlink shared channel (NPDSCH) based on the at least one NB-IoT DL subframe.
