Claim of US Patent No. 10,694,511

1. A method for a terminal receiving or transmitting a signal on a plurality of component carriers (CCs) in a wireless communication system, the method comprising:performing blind decoding on multi-CC downlink control information in a search space of a specific CC, wherein the multi-CC downlink control information includes information on scheduling K number of CCs among N number of the plurality of CCs; and
receiving a downlink data channel or transmitting an uplink control channel or a data channel on the K number of CCs according to the multi-CC downlink control information,
wherein the multi-CC downlink control information includes an N-bits bitmap, a K number of scheduling information fields, and UL grant-related scheduling information,
wherein each of the N-bits bitmap informs whether each of the N number of the plurality of CCs is scheduled,
wherein each of the K number of scheduling information fields is scheduling information on each of the K number of CCs,
wherein the UL grant-related scheduling information is scheduling information on a UL CC associated with a DL CC scheduled by the multi-CC downlink control information,
wherein the multi-CC downlink control information comprises transmission mode (TM)-dependent multi-CC downlink control information or fallback multi-CC downlink control information,
wherein the multi-CC downlink control information is received when a number of the plurality of CCs is equal to or greater than a predetermined number, and
wherein N and K are positive integers, N is divisible by K, and N?K?2.
