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

A method of decoding a downlink signal in a wireless communication system, the method performed by a user equipment (UE), the method comprising:

• receiving, from a base station (BS), rate-matching pattern information indicating a rate-matching resource having a repetition period;
• and
• decoding a downlink shared channel using the rate-matching pattern information,
• wherein the rate-matching pattern information includes a first bitmap indicating a frequency resource region, a second bitmap indicating a time resource region, and a third bitmap indicating one or more time units in which a rate-matching resource indicated by the first bitmap and the second bitmap is configured among a plurality of time units within the repetition period.

A method of transmitting a downlink signal in a wireless communication system, the method performed by a base station (BS), the method comprising:

• transmitting, to a user equipment (UE), rate-matching pattern information indicating a rate-matching resource having a repetition period;
• performing resource element mapping for a downlink shared channel based on the rate-matching pattern information;
• and
• transmitting the downlink shared channel,
• wherein the rate-matching pattern information includes a first bitmap indicating a frequency resource region, a second bitmap indicating a time resource region, and a third bitmap indicating one or more time units in which a rate-matching resource indicated by the first bitmap and the second bitmap is configured among a plurality of time units within the repetition period.

A user equipment (UE) for decoding a downlink signal in a wireless communication system, the UE comprising:

• a transmitter and a receiver;
• and
• a processor configured to control the transmitter and the receiver,
• wherein the processor is configured to receive rate-matching pattern information indicating a rate-matching resource having a repetition period from a base station (BS) through the receiver, and to decode a downlink shared channel using the rate-matching pattern information, and
• wherein the rate-matching pattern information includes a first bitmap indicating a frequency resource region, a second bitmap indicating a time resource region, and a third bitmap indicating one or more time units in which a rate-matching resource indicated by the first bitmap and the second bitmap is configured among a plurality of time units within the repetition period.

A base station (BS) for transmitting a downlink signal in a wireless communication system, the BS comprising:

• a transmitter and a receiver;
• and
• a processor configured to control the transmitter and the receiver,
• wherein the processor is configured to transmit, to a user equipment (UE), rate-matching pattern information indicating a rate-matching resource having a repetition period, to perform resource element mapping for a downlink shared channel based on the rate-matching pattern information, and to transmit the downlink shared channel, and
• wherein the rate-matching pattern information includes a first bitmap indicating a frequency resource region, a second bitmap indicating a time resource region, and a third bitmap indicating one or more time units in which a rate-matching resource indicated by the first bitmap and the second bitmap is configured among a plurality of time units within the repetition period.
