Abstract: A method of a base station may comprise: transmitting, to a terminal, a higher layer message including a first table mapping between cell groups and indicators each indicating the cell groups; transmitting, to the terminal, multi-cell scheduling control information; transmitting, to the terminal, data through multiple cells based on the higher layer message and the multi-cell scheduling control information; and receiving, from the terminal, a response message for the data transmitted through the multiple cells based on the multi-cell scheduling control information, wherein the multi-cell scheduling control information includes first information indicating one cell group at least among the cell groups and uplink resource allocation information.
