4. The method according to claim 1 , wherein the transmitting of the control information to the user equipment is performed by transmitting the control information including information indicating one of the indexes to the user equipment.
5. The method according to claim 4 , wherein the control information is DL assignment DL control information, and
wherein the transmitting of the control information to the user equipment is performed by transmitting the DL assignment DL control information including information indicating one of the indexes to the user equipment through a DL control channel.
6. The method according to claim 1 , wherein the OFDM symbol allocation information for the UL data channel (PUSCH) transmission/reception includes one or more starting OFDM symbols and one or more lengths.
7. The method according to claim 1 , wherein the transmitting of the time-domain resource configuration information to the user equipment is performed by transmitting the time-domain resource configuration information in the form of the table for the UL data channel (PUSCH) transmission/reception to the user equipment through user equipment-specific high layer signaling.
8. A method of a user equipment for allocating a time-domain resource for downlink (DL) data channel (PDSCH) transmission/reception or uplink (UL) data channel (PUSCH) transmission/reception, the method comprising:
allocating the time-domain resource based on a slot or a mini-slot of a subframe as a unit of an orthogonal frequency division multiplexing (OFDM) symbol and at the same time, receiving, from a base station, time-domain resource configuration information including OFDM symbol allocation information for OFDM symbols used for the DL data channel (PDSCH) transmission/reception or the UL data channel (PUSCH) transmission/reception in the slot or the mini-slot, wherein the mini-slot comprises fewer symbols than the slot; and
receiving, from the base station, control information selecting one of the symbol allocation information included in the time-domain resource configuration information,
wherein for allocating the time-domain resource for the DL data channel (PDSCH) transmission/reception, the time-domain resource configuration information includes, in the form of a table, the OFDM symbol allocation information and indexes indicating each of the symbol allocation information for each user equipment, and
wherein for allocating the time-domain resource for the UL data channel (PUSCH) transmission/reception, the time-domain resource configuration information includes, in the form of a table, the OFDM symbol allocation information and indexes indicating each of the symbol allocation information for each user equipment.
9. The method according to claim 8 , wherein the OFDM symbol allocation information for the DL data channel transmission/reception includes one or more starting OFDM symbols and one or more lengths.
10. The method according to claim 8 , wherein the receiving of the time-domain resource configuration information from the base station is performed by transmitting the time-domain resource configuration information in the form of the table for the DL data channel (PDSCH) transmission/reception by the base station to the user equipment through user equipment-specific high layer signaling.
11. The method according to claim 8 , wherein the receiving of the control information from the base station is performed by transmitting the control information including information indicating one of the indexes by the base station to the user equipment.
