Method and user equipment for transmitting uplink signal, and method and base station for receiving uplink signal

A user equipment for transmitting uplink data in a wireless communication system, the user equipment comprising:

• a transceiver;
• and
• a processor configured to:
• control the transceiver to receive downlink control information including information on a target code rate for the uplink data,
• determine a channel code among a plurality of channel codes based on the target code rate,
• encode the uplink data based on the determined channel code, and
• control the transceiver to transmit the encoded uplink data,
• wherein the plurality of channel codes support different ranges of code rates, respectively, and
• wherein the plurality of channel codes are low density parity check codes.

An apparatus for controlling transmission of uplink data in a wireless communication system, the apparatus comprising:

• a processor, and
• a memory that is operably connectable to the processor and that has stored thereon instructions which, when executed, cause the processor to perform operations comprising:
• receiving downlink control information including information on a target code rate for the uplink data through a transceiver,
• determining a channel code among a plurality of channel codes based on the target code rate,
• encoding the uplink data based on the determined channel code, and
• transmitting the encoded uplink data through the transceiver,
• wherein the plurality of channel codes support different ranges of code rates, respectively, and
• wherein the plurality of channel codes are low density parity check codes.
