Method for transmitting or receiving wireless signal in wireless communication system and apparatus therefor

In a method for a base station to estimate redundancy version of repetition transmission of a wireless signal performed by a terminal in a wireless communication system, the method comprising:

• configuring multiple resources of the terminal for repetition transmission of the wireless signal semi-statically;
• wherein a redundancy version sequence for repetition transmission of the wireless signal is pre-configured,
• estimating, based on the redundancy version sequence, a redundancy version for repetition transmission of the wireless signal from the remaining resources except for at least one particular resource among the multiple resources, and
• estimating a redundancy version for repetition transmission of the wireless signal from the at least one particular resource based on a redundancy version value pre-configured for the at least one particular resource.

In a terminal performing repetition transmission of a wireless signal in a wireless communication system, the terminal comprising:

• a transceiver for transmitting and receiving a wireless signal;
• and
• a processor connected functionally to the transceiver,
• wherein the processor is configured to:
• receive a configuration of multiple resources for repetition transmission of the wireless signal semi-statically from a base station;
• wherein a redundancy version sequence for repetition transmission of the wireless signal is pre-configured,
• perform repetition transmission of the wireless signal based on the redundancy version sequence on the remaining resources except for at least one particular resource among the multiple resources, and
• perform repetition transmission of the wireless signal on the at least one particular resource based on a redundancy version value pre-configured for the at least one particular resource.
