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.
Claims20
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.
A wireless device, comprising:
- a transceiver;
- a receiver;
- and
- a controller which controls the transceiver and receiver thereby performing operations including:
- receiving, from a base station, 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
- 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.
An operation method of wireless device, comprising:
- receiving, from a base station, a radio resource control (RRC) signal including information on one or more allocations of a time-domain resource,

- 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.
