Method and device for allocating data channel resource for next-generation wireless access network
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.
1. A base station, comprising:
a transceiver;
a receiver; and
a controller which controls the transceiver and receiver thereby performing operations including:
transmitting, to a wireless device, a radio resource control (RRC) signal including information on one or more allocations of a time-domain resource,
wherein the time-domain resource includes at least one or more orthogonal frequency-division multiplexing (OFDM) symbols,
wherein, based on the information, a number of OFDM symbols are determined for a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH), and
wherein the determined number of OFDM symbols is smaller than or equal to a number of OFDM symbols included in a slot; and
transmitting, to the wireless device, downlink control information (DCI), including a field including a bit string,
wherein the bit string in the field relates to a row index of an allocation table, and
wherein the allocation table includes information on a starting OFDM symbol and the number of the OFDM symbols which is smaller than or equal to the number of OFDM symbols included in the slot.

8. A wireless device, comprising:
a transceiver;
a receiver; and
a controller which controls the transceiver and receiver thereby performing operations including:

wherein the time-domain resource includes at least one or more orthogonal frequency-division multiplexing (OFDM) symbols,
wherein, based on the information, a number of OFDM symbols are determined for a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH), and
wherein the determined number of OFDM symbols is smaller than or equal to a number of OFDM symbols included in a slot; and
receiving, from the base station, downlink control information (DCI), including a field including a bit string,
wherein the bit string in the field relates to a row index of an allocation table, and
wherein the allocation table includes information on a starting OFDM symbol and the number of the OFDM symbols which is smaller than or equal to the number of OFDM symbols included in the slot.
