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
An operation method of a wireless device, the method comprising:
- receiving, by the wireless device, downlink control information (DCI) including time domain resource allocation information;
- receiving, by the wireless device, a physical downlink shared channel (PDSCH) or transmitting, by the wireless device, a physical uplink shared channel (PUSCH) based on a starting orthogonal frequency division multiplexing (OFDM) symbol and a number of OFDM symbols counting from the starting OFDM symbol in a slot, after receiving the DCI,
- wherein the time domain resource allocation information included in the DCI relates to row index information of an allocation table, and
- wherein the starting OFDM symbol and the number of OFDM symbols are identified based on the row index information of the allocation table.
A wireless device, comprising:
- a transmitter;
- a receiver;
- and
- a controller which controls the transmitter and the receiver thereby performing operations including:
- receiving downlink control information (DCI) including time domain resource allocation information;
- receiving a physical downlink shared channel (PDSCH) or transmitting a physical uplink shared channel (PUSCH) based on a starting orthogonal frequency division multiplexing (OFDM) symbol and a number of OFDM symbols counting from the starting OFDM symbol in a slot, after receiving the DCI,
- wherein the time domain resource allocation information included in the DCI relates to row index information of an allocation table, and
- wherein the starting OFDM symbol and the number of OFDM symbols are identified based on the row index information of the allocation table.
A base station, comprising:
- a transmitter;
- a receiver;
- and
- a controller which controls the transmitter and the receiver thereby performing operations including:
- transmitting downlink control information (DCI) including time domain resource allocation information;
- and
- transmitting a physical downlink shared channel (PDSCH) or receiving a physical uplink shared channel (PUSCH) based on a starting orthogonal frequency division multiplexing (OFDM) symbol and a number of OFDM symbols counting from the starting OFDM symbol in a slot, after transmitting the DCI,
- wherein the time domain resource allocation information included in the DCI relates to row index information of an allocation table, and
- wherein the starting OFDM symbol and the number of OFDM symbols are identified based on the row index information of the allocation table.
An operation method of a base station, the method comprising:
- transmitting, by the base station, downlink control information (DCI) including time domain resource allocation information;
- transmitting, by the base station, a physical downlink shared channel (PDSCH) or receiving, by the base station, a physical uplink shared channel (PUSCH) based on a starting orthogonal frequency division multiplexing (OFDM) symbol and a number of OFDM symbols counting from the starting OFDM symbol in a slot, after transmitting the DCI,
- wherein the time domain resource allocation information included in the DCI relates to row index information of an allocation table, and
- wherein the starting OFDM symbol and the number of OFDM symbols are identified based on the row index information of the allocation table.
