Abstract
Provided is s a method for a base station to allocate a time interval resource to transceive a downlink data channel (PDSCH) or an uplink data channel (PUSCH). The method include allocating a time interval resource for each OFDM symbol on the basis of a slot or a mini-slot, transmitting, to a terminal, time interval resource configuration information including OFDM symbol allocation data for OFDM symbols used for data channel transception in the slot or the mini-slot, and transmitting, to the terminal, control information selecting one of the symbol allocation data included in the time interval resource configuration information.

A method of a base station 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, transmitting, to a user equipment, 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
- transmitting, to the user equipment, 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.
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.
