Claim of US Patent No. 10,772,090

10. A base station (BS) for transmitting downlink data in wireless communication, the BS comprising:a transceiver for transmitting and receiving a radio signal with a user equipment (UE); and
a processor controlling the transceiver,
wherein the processor is configured to:
control the transceiver to transmit information related to control resource sets for Downlink Control Information (DCI);
control the transceiver to transmit, 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 transmit the downlink data 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.
