Method for transmitting/receiving downlink data and device therefor

A user equipment (UE) for receiving downlink data in wireless communication, the UE comprising:

• a transceiver for transmitting and receiving a radio signal with a base station (BS);
• and
• a processor controlling the transceiver,
• wherein the processor is configured to:
• control the transceiver to receive information related to control resource sets for Downlink Control Information (DCI);
• control the transceiver to receive, via a higher layer, rate matching information related to reception of the downlink data in each of the control resource sets;
• and
• control the transceiver to receive the downlink data based on whether DCI is detected in the control resource sets and the rate matching information,
• wherein the downlink data is not received in a first control resource set, among the control resource sets, in which the DCI is not detected based on the rate matching information including first information,
• wherein the downlink data is received in a second control resource set in which the DCI is detected among the control resource sets based on the rate matching information including the first information, and
• wherein the first information is related to information indicating rate-matching of the downlink data for a control resource set in which the DCI is detected.

A method for transmitting downlink data by a base station (BS) in wireless communication, the method comprising:

• transmitting information related to control resource sets for Downlink Control Information (DCI);
• transmitting, via a higher layer, rate matching information related to reception of the downlink data in each of the control resource sets;
• and
• transmitting the downlink data in the control resource sets based on whether DCI is mapped to the control resource sets and the rate matching information,
• wherein the downlink data is not transmitted in a first control resource set, among the control resource sets, in which the DCI is not mapped based on the rate matching information including first information,
• wherein the downlink data is received in a second control resource set in which the DCI is detected among the control resource sets based on the rate matching information including the first information, and
• wherein the first information is related to information indicating rate-matching of the downlink data for a control resource set in which the DCI is detected.

An apparatus for receiving downlink data in wireless communication, the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive information related to control resource sets for Downlink Control Information (DCI);
• receive, via a higher layer, rate matching information related to reception of the downlink data in each of the control resource sets;
• and
• receive the downlink data in the control resource sets based on whether DCI is detected in the control resource sets and the rate matching information,
• wherein the downlink data is not received in a first control resource set, among the control resource sets, in which the DCI is not detected based on the rate matching information including first information,
• wherein the downlink data is received in a second control resource set in which the DCI is detected among the control resource sets based on the rate matching information including the first information, and
• wherein the first information is related to information indicating rate-matching of the downlink data for a control resource set in which the DCI is detected.
